[080] The cabin is defined by a floor element 61, a ceiling element 63, a side wall element 65, a window 70, and an internal window frame element, which covers the vicinity of that window 70. In this cabin , a seating device 80, installed on the floor element 61, and a luggage platform 90, installed on a ceiling above the seating device 80, are arranged.

[083] The luggage platform 90 is arranged above each of the sets of two seating devices 80, arranged in the right and left directions. The luggage platform 90 includes a pallet body 91, having an opening 92 provided on one side of the aisle, and a cover 93, which closes the opening 92 of the pallet body 91.
[084] First embodiment [085] A lighting device, according to a first embodiment of the present invention, will be described using Figures 1 to 5.
[086] The lighting device of this embodiment includes an organic EL lighting panel 10, and a panel drive circuit 30, which drives that organic EL lighting panel 10, according to an instruction from a control device 35, as illustrated in Figure 4.
[087] The EL organic lighting panel 10 includes several light-emitting units 11, a charge-generating layer 15 arranged between the various light-emitting units 11, a pair of electrodes (a positive electrode 17a and a negative electrode 17b), supplying power from the panel drive circuit 30 to a stacked body 16, including the light-emitting units 11 and the load-generating layers 15, a transparent substrate 18 disposed on the side opposite the negative electrode 17b of the positive electrode 17a , with respect to positive electrode 17a, a sealing substrate 18b disposed on a side opposite to the side of the
14/48 positive electrode 17a from negative electrode 17b, with respect to negative electrode 17b, a thermal radiation plate 19 disposed on the opposite side to the side of positive electrode 17a, with respect to sealing substrate 18b, and a sealing element 21, which seals an outer periphery of the stacked body 16 and the electrodes 17a and 17b.
[088] The light-emitting unit 11 includes a light-emitting layer 12, which includes a fluorescent organic material or a phosphorescent organic material, a gap transport layer 32 that supports gaps, and an electronic transport layer 14 that carries electrons . The various layers 12, 13 and 14 are stacked in a stacking direction of the stacked body 16 described above. In addition, in this embodiment, the light-emitting unit 11 includes the light-emitting layer 12, the electronic transport layer 14 and the gap transport layer 13, but that embodiment of the present invention is thus not limited. For example, the light-emitting unit can include a gap transport layer, and a light-emitting layer can include a gap injection layer, a gap transport layer, a light-emitting layer and an electronic transport layer , or it can include a gap injection layer, a gap transport layer, a light-emitting layer, an electronic transport layer and an electronic injection layer.
[089] The positive electrode 17a is, for example, a transparent electrode, formed from ITO (Tin Oxide and Indium), or similar. In addition, negative electrode 17b is a reflection electrode formed of Ag, Al or the like. The thermal radiation plate 19 is formed, for example, from an aluminum plate, the surface of which is subjected to an insulation process. The transparent substrate 18 is formed from a transparent glass plate, a plastic plate or the like. The sealing substrate 18b acts as a cover for sealing on the side of the negative electrode 17b, towards the stacked body 16 and the electrodes 17a and 17b. The sealing substrate 18b is formed by a glass plate,
15/48 a plastic plate or the like. In the stacking direction of the stacked body 16, a slight gap is fixed between the sealing substrate 18b and the negative electrode 17b. The gap is filled with a moisture absorber. In addition, for example, the gap can be filled with an inert gas, such as nitrogen or silicone oil, instead of the moisture absorber.
[090] The sealing element 21 is provided to prevent the stacked body 16 from deteriorating, due to external oxygen or water. This sealing element 21 is arranged, for example, on the outer periphery of the stacked body 16 and the electrodes 17a and 17b, between the transparent substrate 18 and the sealing substrate 18b, and connects the substrates 18 and 18b.
[091] In this embodiment, a multiple photoemission structure (MPE), having the various light-emitting units 11, and the charge-generating layer 15, disposed between the various light-emitting units 11, is adopted. The organic EL lighting panel can include a light-emitting unit 11. However, in this embodiment, the MPE structure is adopted as a lighting device for the passenger aircraft, in order to increase reliability and obtain a long service life and low energy consumption.
[092] It is not necessary for the light-emitting layers 12 of the various light-emitting units in the MPE structure to be the same between the light-emitting units 11. The light-emitting layer 12 of each of the various light-emitting units 11 in the MPE structure it can be a combination of a light-emitting layer 12, for emitting red light, a light-emitting layer 12, for emitting green light, and a light-emitting layer 12, for emitting blue light, or a combination of a light-emitting layer 12, for emitting orange light, and a light-emitting layer 12, for emitting blue light. The light-emitting layer 12 emits, as a whole, white or similar light according to the light color mixing action, due to the combination. Besides that,
16/48 two light-emitting layers 12 can be provided for the light-emitting unit 11, one light-emitting layer 12 of two light-emitting layers 12 is for one of red, green and blue, another light-emitting layer 12 is for one of the two remaining colors, and an additional light-emitting layer 12, for the remaining color, can be provided in the other light-emitting unit 11, to produce white light emission by means of a combination of the light-emitting units 11. In addition, a light-emitting layer 12 for red, green and blue can be provided in a light-emitting unit 11, to produce white light emission with the single unit, and several light-emitting units 11 can be combined to constitute a stacked structure.
[093] New materials for each layer constituting the light emitting unit 11 are being developed one by one. Therefore, a known material can be properly selected and used as the material of each layer constituting the light-emitting unit 11. In addition, the organic material of the light-emitting layer 12 can be a low molecular weight base material or polymeric base. In addition, if a phosphorescent organic material is used as the organic material of the light-emitting layer 12, it is possible to obtain 4 times the luminous efficiency of a fluorescent organic material.
[094] For example, an electrically insulating layer, having a specific resistance of 1.0 x 10 ² Q.cm, or a semiconductor layer or a conductive layer, having a specific resistance of 1.0 x or less 10 ² Q.cm, is used as the load-generating layer 15. This load-generating layer 15 includes a layer or several layers. Each layer of the charge-generating layer 15 is formed from a single organic material, an inorganic oxide (molybdenum oxide, vanadium oxide or the like) or a mixture of them. The load-generating layer 15 may have a structure in which a
17/48 organic layer, doped with n-type organic material, and an organic layer, doped with p-type organic material, are stacked. In addition, the load-generating layer 15 may have a structure in which an electrically insulating layer, having a specific resistance of 1.0 x 10 ² Q.cm, is inserted between an organic layer, doped with an organic material. of type n, and an organic layer, doped with an organic material of type p, in order to eliminate the interactions between them, so that the load-generating layer 15 can promote a good release of a current.
[095] In the EL organic lighting panel 10, having an MPE structure, the same current flows in the respective light emitting units 11, and each light emitting unit 11 contributes to emission. In this way, it is possible to emit a lot of light, even with less current, compared to a normal organic EL lighting panel, including a light emitting unit 11.
[096] For example, on the EL organic lighting panel 10, having three light emitting units 11, it is possible to emit the same light as on the EL organic lighting panel, including a light emitting unit 11, even when a current is flowing in the organic EL lighting panel 10 is reduced to 1/3.
[097] Thus, in the EL organic lighting panel 10 having the MPE structure, the same amount of light is obtained with a current lower than the current in the EL organic lighting panel 10, including one of the light emitting units 11, and, in this way, a load of all organic layers is reduced. Therefore, it is possible to increase reliability and obtain a long service life and low energy consumption, as described above.
[098] In current technology, when the time until the luminance reaches 70% of the initial luminance is defined as a lifetime, the lifetime of the organic EL lighting panel 10, of which a color temperature is a neutral white type in an MPE structure, is about 300,000 hours, about 50,000
18/48 hours, about 18,000 hours and about 10,000 hours, when an initial luminance is 300 cd / m ² , 1,000 cd / m ² , 2,000 cd / m ² and 3,000 cd / m ² , respectively, as shown in Figure 5. In addition, the life span of the organic EL lighting panel, of which a color temperature is a type of bulb color in the MPE structure, is about 25,000 hours, about 9,000 hours and about 5,000 hours, when initial luminance is 1,000 cd / m ² , 2,000 cd / m ² and 3,000 cd / m ² , respectively.
[099] A thickness of each of the layers, constituting the light-emitting unit 11, a thickness of the charge-generating layer 15 arranged between the light-emitting units 11 and the thickness of the positive electrode 17a and the negative electrode 17b are tens at hundreds of nm. Therefore, when several light emitting units 11 are included, the thickness of the stacked body is in the order of submicron to micron. In addition, a thickness of the transparent substrate 18 of the thermal radiation plate 19 is about 0.5 to 0.9 mm. Therefore, a thickness of the organic EL lighting panel 3 can be 3 mm or less. Even when another layer, sheet, plate or the like is added, according to other design requirements, such as a high rigidity of the organic EL lighting panel 10, the thickness of the organic EL lighting panel can be 5 mm or less .
[0100] With the EL organic lighting panel, various shapes, such as a square, a rectangle, a circle or a special symbolic shape, however produced as its shape, according to its purpose or place of installation. In addition, with the EL organic lighting panel, for example, various sizes, such as a small organic EL lighting panel, such as 5 x 5 cm ² , and a relatively large organic EL lighting panel, such as 10 x 10 cm ² , 15 x 15 cm ² or 30 x 30 cm ² , can be produced as your size, when the panel is a square. In addition, various sizes, such as an EL lighting panel
19/48 small organic, such as 3 x 15 cm ² , and a relatively large organic EL lighting panel, such as 6 x 30 cm ² , 7.5 x 30 cm ² or 10 x 30 cm ² , can be produced as its size, when the panel is a rectangle. For example, the organic EL lighting panel 10 includes, in an outer peripheral part of the transparent substrate 18, an element, such as a frame including connections for supplying power from the panel drive circuit 30 to the electrode pair 17a and 17b. Therefore, about 70% of the external size of the organic EL lighting panel 10 becomes an area of light emission.
[0101] In the organic EL lighting device, the drive circuit is generally provided entirely with this organic EL lighting panel behind the organic EL lighting panel as described above. However, in this embodiment, the organic EL lighting panel 10 and the panel drive circuit 30 are installed in separate locations distant from each other.
[0102] In this embodiment, the organic EL lighting panel 10 is installed on a surface on the floor side in the pallet body 91 of the luggage platform 90, so that the transparent substrate 18 of the organic EL lighting panel is directed to the floor , as illustrated in Figures 1 to 3. In addition, the panel drive circuit 30, which drives this EL organic lighting panel 10, can be provided, for example, in a position relatively close to the EL organic lighting panel 10, such as a side plate facing opening 92 in the platform body 91, or between the luggage platform 90 and the ceiling, but it can be provided in a relatively distant position from the organic EL lighting panel 10, such as an element defining a luggage compartment.
[0103] The EL organic lighting panel 10 is curved along and fixed to a curved surface on the floor side of the pallet body 91 with an adhesive medium, such as an adhesive or double-sided tape or fixing medium such
20/48 as screws. In addition, when the EL organic lighting panel 10 is attached to the curved surface, and the radius of curvature of that surface is relatively large, a glass plate can be used as the transparent substrate 18. On the other hand, if the radius of curvature is relatively small, a highly flexible plastic plate is preferably used instead of the glass plate. Furthermore, even in the embodiments to be described below, when the surface on which the EL organic lighting panel is fixed is curved, that EL organic lighting panel can be curved along and fixed on the surface.
[0104] Eventually, the cabin illuminance criteria for a passenger aircraft are determined as industry standards by SAE Aerospace, which is an aerospace series published by the Society of Automotive Engineers (hereinafter referred to as SAE). In SAE Aerospace's Aerospace Information Report 512 (hereinafter AIR 512), the illuminance in a seating area on a lower surface of a baggage platform is defined as equal to or greater than 53.83 Ix at the time of boarding, and equal to or greater than 21.53 Ix, during a night flight.
[0105] In this embodiment, to satisfy the illuminance criteria described above, in a space 1 m directly under the luggage platform 90, for example, two organic EL lighting panels 10, having a luminance of 1,000 to 2,000 cd / m ² and an external size of 7.5 x 30 cm ² , are installed side by side in a longitudinal direction on the surface of the floor side of the luggage platform 90.
[0106] The luminance and external size of the EL organic lighting panel 10, illustrated above, were obtained using equations (1) and (2) below.
[0107] In addition, the light intensity I (cd) of the light source and the illuminance E (Ix) of a lighted part of the light source are inversely proportional to a square of a distance R (m), as illustrated in equation (1)
21/48 below.
E = l / R ² (1) [0108] In addition, the light intensity I (cd) of the light source is a product of the luminance L (cd / m ² ) of the light source and an area S (m ² ) of an appearance seen directly under the light source, as shown in equation (2) below.
I = LS (2) [0109] In addition, equation (1) is an equation used for calculating illuminance in a point light source, but it is applied in a case of an organic EL lighting panel, which is a source flat light for simple calculation. In addition, as the area S (m ² ) of an appearance seen directly under the light source, the light emitting area (m ² ) of the organic EL lighting panel is used instead. In addition, since the light emitting area is about 70% of the external size of the organic EL lighting panel 10, as described above, 70% of the external size is the light emitting area.
[0110] If the initial luminance of the EL organic lighting panel 10 is 2,000 cd / m ² , the life span of the EL organic lighting panel 10 is around 18,000 hours, if the EL organic lighting panel 10 is a neutral white type, and about 9,000 hours if the organic EL lighting panel 10 is a bulb color type, as described above. In this way, this EL organic lighting panel 10 is an alternative to a fluorescent lamp having a life span of around 10,000 hours, on an illuminance basis.
[0111] As described above, in this embodiment, since the organic EL lighting panel 10, having a thickness of 5 mm or less, is installed on the floor side of the luggage platform 90, it is possible to illuminate the seat part 82 of the floor surface, without substantially reducing the space between the luggage platform 90 and the seat part 82 of the seat 81, directly under the luggage platform 90, and a space between the luggage platform 90 and the surface
22/48 floor, directly under the luggage platform 90. In addition, on existing generic passenger aircraft, to avoid substantially reducing the space between the luggage platform and the seat part of the seat directly under the luggage platform , a lighting device, such as a fluorescent lamp, is not installed on a surface on the floor side of the luggage platform. Therefore, on existing generic passenger aircraft, for example, a reading light is used in its place to illuminate the luggage platform and the seat part of the seat directly under the luggage platform.
<Example of modification of the first embodiment [0112] In the following, an example of modification of the first embodiment, described above, will be described using Figures 6 and 7.
[0113] In the lighting device of this modification, a through opening 92a or a lowered part is formed in a pallet plate on the floor side in the pallet body 91 of the luggage pallet 90, as illustrated in Figure 6. In this example of As a modification, the organic EL lighting panel 10a is installed on the floor board on the floor side in the floor body 91, so that the transparent substrate 18 is directed towards the floor side.
[0114] Even in this modification example, once the EL organic lighting panel 10a is installed on the floor side of the luggage platform 90, it is possible to obtain the same effects as those in the first embodiment described above.
[0115] In addition, when the through opening 92a is formed in the platform plate on the floor side in the platform body 91 of the luggage platform 90 and the organic EL lighting panel 10a is inserted into the through opening 92a, it is necessary ensure relatively high rigidity, since the luggage load on the luggage shelf 90 is applied to the organic EL lighting panel 10a. Therefore, in this case, it is preferable to collect the transparent substrate 18, the plate
23/48 of thermal radiation 19, and the various light emitting units 11 arranged between them, and provide a frame 22, which covers its outer peripheries and a rear surface side of the thermal radiation plate 19, as illustrated in Figure 7. In addition, in frame 22, a through hole can be formed in a part covering the rear surface side of the thermal radiation plate 19, in order to guarantee a thermal radiation effect of the thermal radiation plate 19. Furthermore, even when frame 22 is provided to ensure relatively high rigidity, the thickness of the organic EL lighting panel 10a can be eliminated to a value of 5 mm or less, as described above.
Second embodiment [0116] In the following, a lighting device, according to a second embodiment of the present invention, will be described using Figures 1 and 8.
[0117] The lighting device for this embodiment includes an organic EL lighting panel, and a panel drive circuit that drives that organic EL lighting panel, according to a control device instruction, similarly to the first embodiment. .
[0118] The EL organic lighting panel and the panel drive circuit have the same structure as the structure shown in the first embodiment or in its modification example.
[0119] In this embodiment, the organic EL lighting panel 10b is installed in a part of the ceiling element 63, defining the upper part of the cabin, which is a part directly above the aisle 61 p, so that a transparent substrate 18 of the organic EL lighting panel 10b is directed to the floor, as shown in Figures 1 and 8.
[0120] Several organic EL lighting panels 10b are installed side by side in a longitudinal direction of the aisle 61 p, in a part of the ceiling element 63 directly above the aisle 61 p. The various EL lighting panels
Organic 24/48 10b can be arranged linearly in the longitudinal direction of the aisle 61 p, or can be arranged in the longitudinal direction of the aisle 61 p and shifted to the right and left, as shown in Figure 8, in order to optimize the design characteristics of an aircraft space.
[0121] Eventually, in the AIR 512 described above, the corridor illuminance is defined as being equal to or greater than 21.53 Ix, when boarding and during a night flight, and equal to or greater than 1.08 Ix at night, when passengers are sleeping.
[0122] In this embodiment, to satisfy the illuminance criterion in a space 2 m directly under the ceiling surface, for example, the organic EL lighting panel 10b, having a luminance equal to or greater than 2,000 cd / m ² and a size external 10 x 30 cm ² , is installed in the ceiling element 63. The luminance and the external size of the EL organic lighting panel 10b, illustrated in this specification, were obtained using the equations (1) and (2) presented above.
[0123] If the initial luminance of the 10b EL organic lighting panel is 2,000 cd / m ² , the life span of the 10b EL organic lighting panel is about 18,000 hours, when the 10b EL organic lighting panel is a noon white type, and about 9,000 hours if the organic EL lighting panel 10 is a bulb color type. Thus, this organic EL 10b lighting panel is an alternative to a fluorescent lamp having a life span of around 10,000 hours.
[0124] As described above, in this embodiment, since the organic EL lighting panel 10b, having a thickness of 5 mm or less, is installed in the ceiling element 63, directly above the aisle 61 p, it is possible to illuminate the floor, or the like, without substantially reducing the space between the ceiling surface and the floor, directly under the ceiling surface, in other words,
25/48 without substantially reducing an interval between the head of a passenger (also including the crew as passengers) walking in the aisle 61 p and the ceiling surface.
[0125] Therefore, it is quite preferable that this embodiment be adopted in a small regional jet, in which a space, between a ceiling surface and a floor, directly under the ceiling surface, is small.
[0126] In addition, a structure in which minimal organic EL elements, on a micron scale, that emit single color light, such as red, green and blue, are arranged in parallel in a matrix shape or a line shape , in other words, the same structure of the organic EL lighting panel can be adopted as a structure of the organic EL lighting panel 10b. By adopting this structure, several colors, including white, can be represented due to the moderate color mixing effects of three colors, and a toning function can be optimized. However, with this structure, since the number of connections between the organic EL lighting panel 10b and the panel drive circuit increases, the connection is complicated. Thus, it is preferable that the panel drive circuit, which drives the EL organic lighting panel 10b, is installed close to the EL organic lighting panel 10b.
[0127] Furthermore, although the example in which the various organic EL lighting panels 10b are installed only in the part of the ceiling element 63, directly above the aisle 61 p, has been described above, the organic EL lighting panel 10b can be installed in the part of the ceiling element 63, except in the part directly above the aisle 61 p.
Third embodiment [0128] In the following, a lighting device, according to a third embodiment of the present invention, will be described using Figures 1,9 and 10.
26/48 [0129] The lighting device of this embodiment includes an organic EL lighting panel, and a panel drive circuit that drives that organic EL lighting panel, according to a control device instruction, in a similar manner to the embodiments described above. Even in this embodiment, the organic EL lighting panel and the panel drive circuit have the same structure as the structure illustrated in the first embodiment or in its modification example.
[0130] In this embodiment, an organic EL lighting panel 10c is installed on an inner side of the bed frame 91 on the cover 93 of the luggage bed 90, so that a transparent substrate 18 is directed to the inner side of the bed body 91 , as illustrated in Figures 1,9 and 10.
[0131] Eventually, in the AIR 512 described above, the illuminance of the luggage platform is defined as equal to or greater than 53.82 Ix.
[0132] In this embodiment, to satisfy the illuminance criterion in a space 30 cm directly under the cover, in a state in which the cover 93 of the luggage platform 90 is fully open, for example, the organic EL lighting panel 10c, having a luminance equal to or greater than 300 cd / m ² and an external size of 7.5 x 30 cm ² , it was considered to be installed in this coverage 93.
[0133] The luminance and external size of the EL organic lighting panel 10c, illustrated in this specification, were obtained by equations (1) and (2) presented above. In addition, when the initial luminance is 300 cd / m ² , the life span of the organic EL lighting panel 10c is around 30,000 hours, regardless of the color temperature, as described above.
[0134] As described above, in this embodiment, since the organic EL lighting panel 10c, having a thickness of 5 mm or less, is installed on the inside of the cover 93 of the luggage platform 90, the inside
27/48 of the luggage platform 90 is illuminated, without substantially reducing the internal space of the luggage platform 90. Therefore, in this embodiment, it is possible to improve the visibility on the luggage platform 90 and contribute to reduce the time spent for confirmation on the internal side. baggage platform 90 for crew and prevent passengers from forgetting their luggage. Furthermore, when the cover 93 of the luggage compartment 90 is fully open, not only the internal space of the luggage compartment 90, but also the aisle 61 p can be illuminated, and the loading and unloading of the luggage to and from the luggage compartment 90 luggage by passengers can be easily carried.
[0135] In addition, in this embodiment, the organic EL lighting panel 10c can be connected in response to the control circuit instruction in the take-off and landing time zones, or the organic EL lighting panel 10c can be connected accordingly with the opening and closing of the luggage compartment cover 90. In this case, it is preferable that the opening and closing of the door (the luggage compartment cover 90) are detected by a key, and the organic EL lighting panel 10c can be turned on when the door is open and turned off when the door is closed.
Fourth embodiment [0136] In the following, a lighting device, according to a fourth embodiment of the present invention, will be described using Figures 1 and 11 to 13.
[0137] The lighting device of this embodiment includes an organic EL lighting panel, and a panel drive circuit, which drives that organic EL lighting panel, according to a control device instruction, similarly to the embodiments described above.
[0138] In this embodiment, an EL organic lighting panel 10d is installed in a part of the floor element 61, defining the bottom of the cabin,
28/48 which is a part of the corridor 61 p, so that a transparent substrate 18 of the organic EL lighting panel 10d is directed towards the ceiling, as illustrated in Figures 1 and 11. More specifically, the organic EL lighting panel 10d is installed in a position in the aisle 61 p next to the seat on the side of the aisle 61 p, between the two seat devices 80, arranged at a gap in the right and left directions, and a position in the aisle 61 p next to the seat in the side of the aisle 61 p on the other seating device 80, located on an opposite side with the aisle 61 p interposed between them.
[0139] In the organic EL lighting panel 10d of that embodiment, a light storage layer 23, including a light storage material, is added to the organic EL lighting panels 10 and 10a, in the first embodiment and in its modification example (Figures 4 and 7), as illustrated in Figure 12. Examples of the light storage material include a material based on zinc sulfide, a material based on strontium aluminate and an oxide based on alumina. The light storage layer 23 is formed of an ink containing a light storage material, or an element in which a light storage material is covered with a foil.
[0140] Since the light storage layer 23 has a small thickness and optical transparency, the light storage layer 23 can be arranged, for example, on a surface opposite the side of the transparent substrate 18, on which the positive electrode 17a is disposed, or between the positive electrode 17a and the transparent substrate 18. Furthermore, this light storage layer 23 can be disposed between the negative electrode 17b and the thermal radiation plate 19. Specifically, the Light storage 23 can be arranged between negative electrode 17b and sealing substrate 18b, or between sealing substrate 18b and organic EL lighting panels 19. In this case, negative electrode 17b must be a transparent electrode, so
29/48 similar to positive electrode 17a. Furthermore, when the light storage layer 23 is disposed between the sealing substrate 18b and the thermal radiation plate 19, it is necessary that the sealing substrate 18b is transparent. In addition, it is preferable that a surface of the thermal radiation plate 19, on the side on which the light storage layer 23 is arranged to be a reflection surface. Furthermore, since the thickness of the light storage layer 23 is substantially equal to the thickness of the other layers, the thickness of this organic EL lighting panel 10d does not exceed 5 mm, even when the light storage layer 23 is added .
[0141] Eventually, in the AIR 512 described above, the illuminance in the corridor is defined as equal to or greater than 21.53, when boarding and during a night flight, and equal to or greater than 1.08 Ix, when passengers are sleeping.
[0142] In this embodiment, to satisfy the illuminance criterion in a space of 10 cm, directly above the floor surface, for example, the organic EL lighting panel 10d, having a luminance equal to or greater than 15 cd / m ² and an external size of 7.5 x 30 cm ² , was considered to be installed on the floor element 61. The luminance and external size of the EL organic lighting panel 10d illustrate, in this case, that they were obtained using the equations (1 ) and (2) mentioned above. In addition, when the initial luminance is equal to 15 cd / m ² , the useful life period is equal to or greater than 300,000 hours, regardless of the color temperature, as described above.
[0143] As described above, in this embodiment, since the organic EL lighting panel 10d, having a thickness equal to or greater than 5 mm, is installed in the aisle 61 p, as described above, the aisle 61 p can be shown without disrupt a passenger's floor. Furthermore, since the organic EL lighting panel 10d includes the light storage layer 23, the organic EL lighting panel 10d can show the 61p corridor, even in a
30/48 emergency, when all the power on the aircraft is turned off, and in this way, the organic EL lighting panel 10d can serve as a guide light.
[0144] In addition, the EL organic lighting panel 10d serves as a signal light for a seat number, when a letter, indicating the seat number, is applied to the EL organic lighting panel 10d, as illustrated in Figure 13 In that case, a sheet with a seat number can be added to the organic EL lighting panel 10d, as will be described in the tenth and eleventh embodiments, which will be described using Figures 26 to 28. Generally, the number of seat on the passenger aircraft is often attached to the luggage platform. In this way, when the EL organic lighting panel 10d, functioning as the signal light for the seat number, is installed in the aisle 61 p, a small person or a child, who cannot easily recognize the seat number on the platform luggage 80, you can be sure of the seat number when the aisle is full of people, such as before take-off and after landing.
Fifth embodiment [0145] In the following, a lighting device, according to a fifth embodiment of the present invention, will be described using Figures 1 and 14.
[0146] The lighting device of this embodiment includes an organic EL lighting panel, and a panel drive circuit, which drives the organic EL lighting panel, according to a control device instruction, similarly to all the embodiments described above. Even in this embodiment, the organic EL lighting panel and the panel drive circuit have the same structure as that shown in the first embodiment of the modification example.
[0147] In this embodiment, the EL organic lighting panel 10e is installed on the floor side of the seat part 82 of the seat device 80, and,
31/48 more specifically, on the floor side of the seat part support beam 88a, supporting the seat part 82, so that the transparent substrate 18 is directed to the floor, as illustrated in Figures 1 and 14.
[0148] Eventually, in the AIR 512 described above, the illuminance in the corridor is defined as equal to or greater than 21.53, when boarding and during a night flight, and equal to or greater than 1.08 Ix, when passengers are sleeping, but the illuminance in a foot space of a lower part of the seat is not defined in the AIR 512. However, it is also preferable that the same illuminance as that in the aisle is guaranteed in the foot space of the lower part of the seat.
[0149] In this embodiment, to satisfy the criterion of illumination in the 61 p corridor, in a space 30 cm directly under the seat, for example, for example the EL organic lighting panel 10e, having a luminance equal to or greater than 150 cd / m ² and an external size of 7.5 x 30 cm ² , was considered to be installed in the support beam of the seat part 88a. The luminance and external size of the EL organic lighting panel 10e illustrated in this case were obtained using equations (1) and (2) mentioned above. In addition, when the initial luminance is equal to 150 cd / m ² , the useful life period is equal to or greater than 300,000 hours, regardless of the color temperature, as described above.
[0150] As described above, in this embodiment, since the organic EL lighting panel 10e, having a thickness of 5 mm or less, is installed on the floor side of the support beam of the seat part 88a, as described above , the bottom of the seat can be illuminated without substantially reducing the space at the bottom of the seat, which is the luggage space or foot space. Therefore, in this embodiment, it is possible to improve visibility at the bottom of the seat, and easily load or unload luggage at the bottom
32/48 bottom of the seat and easily confirm lost items and obstacles at the time of passage. Furthermore, in this embodiment, once the foot space is clear, the foot space appears to be wider for the passenger, and their comfort can be improved.
[0151] Furthermore, in this embodiment, although the EL organic lighting panel 10e is provided on the support beam of the seat part 88a, the EL organic lighting panel 10e can be installed directly on the floor side surface of the seat 82 from seat 81, provided that the light is not blocked by the support beam of the seat part 88a.
Sixth embodiment [0152] Next, a lighting device, according to a sixth embodiment of the present invention, will be described using Figures 15A to 19.
[0153] The lighting device of this embodiment includes a 10f organic EL lighting panel, and a panel drive circuit 30, which drives the 10f organic EL lighting panel, according to a control device instruction, so similar to all embodiments, as illustrated in Figure 16. Furthermore, the lighting device of that embodiment includes a panel connector 31, which secures the organic EL lighting panel 10f to a back support surface 83a of the back support part. back 83 on seat 81, a light shield plate 32, which blocks the diffusion of light from the organic EL lighting panel 10f, and a switch 33, which turns the organic EL lighting panel 10f on or off.
[0154] The EL organic lighting panel 10f of this embodiment is basically the same as the EL organic lighting panel 10a (Figure 7), which is an example of modifying the first embodiment. The EL organic lighting panel 10f is a panel with relatively high rigidity, having a frame.
[0155] The EL organic 10f lighting panel is attached to a part for
33/48 back support 83, so that it is able to be opened or closed, in a closed state, in which the transparent substrate 18 of the EL organic lighting panel 10f faces the back surface 83a of the back support part 83 , as shown in Figure 15A, and an open state, in which the transparent substrate 18 forms an angle with respect to the rear surface 83a, as illustrated in Figure 15B, by means of the panel connector 31 described above. For example, a friction joint capable of maintaining an angle when the passenger causes the organic EL 10f lighting panel to be at a desired angle with respect to the backrest part 83, so that it is adopted by the panel connector 31.
[0156] This panel connector 31 pivots to the organic EL lighting panel 10f on the backrest part 83, with respect to a virtual axis along the back surface 83a of the backrest part 83 and parallel to the floor surface , thereby promoting the opening and closing of the EL organic lighting panel 10f. The organic EL lighting panel 10f is, in this example, a rectangle, and is attached to the backrest part 83 by panel connector 31 with one of a pair of long sides of the rectangle being parallel to the floor surface.
[0157] The light shield plate 32 described above is attached at both ends of the EL organic lighting panel 10f, in a direction in which the virtual axis described above, that is, a direction to the right and left of the fuselage, in order to be able to open and close, between a closed state, in which the light shield plate 32 faces the transparent substrate 18, and an open state, in which the light shield plate 32 forms a angle to the transparent substrate 18. In this embodiment, both end parts of the EL organic lighting panel 10f, in the right and left direction of the fuselage, are the short sides of the EL organic lighting panel 10f
34/48 rectangular.
[0158] The key 33 described above is arranged on the side of the rear surface of the backrest part 83 of the seat 81 and on a part covered with the EL organic lighting panel 10f, which is in the closed state. This switch 33 is provided in a connection, which connects the panel drive circuit 30 with the organic EL lighting panel 10f. This switch 33 detects the opening or closing of the EL organic lighting panel 10f, electrically connects the panel drive circuit 30 with the EL organic lighting panel 10f in the open state, and electrically disconnects the panel drive circuit 30 from the panel 10f organic EL lighting system in closed state.
[0159] In this embodiment, when the passenger seated in his seat 81 reads or similar, the organic EL lighting panel 10f, attached to the backrest part 83 of the front seat 81, is forced to remain in the open state. When the 10f organic EL lighting panel enters the open state, switch 33 detects that state and electrically connects the 10f organic EL lighting panel with the panel drive circuit 30, to make the 10f organic EL lighting panel stay on. in an ON state.
[0160] As the angle of the organic EL lighting panel 10f, with respect to the backrest part 83, increases, an amount of light that reaches a hand of the passenger of the organic EL lighting panel 10f becomes large. Therefore, when the passenger wants the space of his hand (including the table space) to be clear, the passenger can increase the angle of the EL organic lighting panel 10f with respect to the backrest part 83.
[0161] In addition, for example, when it is desired that the light of the organic EL lighting panel 10f does not reach an adjacent sleeping passenger, the angle of the light shield plate 32, with respect to the organic EL lighting panel 10f, can adjusted accordingly.
35/48 [0162] Eventually, in the Aerospace Recommended Practice 378 (hereinafter, ARP 378) of SAE Aerospace, mentioned above, the minimum illuminance of 269 lx and the maximum illuminance of 519 lx are defined in the central part a of table 84, inside the table surface, and the minimum illuminance of 54 lx and the maximum illuminance of 215 lx are defined at the table end position 84, inside the table surface, as illustrated in Figure 19.
[0163] In addition, a maximum of 16 lx is set in position f, off the 114 mm table, in a right and left direction from the d end position of table 84, on the extended surface of the table. In ARP 378, the illuminance criteria are presented in units of fc, that is, pellets, while the illuminances are presented in this case in units of lx, using a conversion equation of 1 fc = 10.75 lx.
[0164] In this embodiment, when a distance between the 10f organic EL lighting panel and the table surface is 30 cm, in a state in which the 10f organic EL lighting panel, having an external size of 10 x 30 cm ² , is open to the table surface, the luminance of the EL organic 10f lighting panel is equal to or greater than 2,000 cd / m ² , in order to satisfy the above-mentioned illuminance criterion.
[0165] The luminances of the EL organic lighting panel 10f, illustrated above, were obtained using equation (3) presented below. Specifically, firstly, several luminances are considered as the luminances of the organic EL lighting panel, and the illuminance E _h in the various positions a to f on the table surface and on its extended surface, in the respective luminances, is obtained using equation (3) shown below. Then, it is determined whether the illuminance E _h , in the various positions a to f on the table surface and on its extended surface, satisfies the illuminance criterion mentioned above, and the luminance of the organic EL lighting panel, when the illuminance criterion is satisfied. , is determined
36/48 as the luminance of a 10f organic EL lighting panel, to be adopted.
[Equation 1]Λ l, i, ..... V · 1 -I ^ώ 2 v x ·% / r ) , 7 Δ ² T.fe ² 5 'A
[0166] In this case, in equation (3), E _h + horizontal illuminance (lx), and L: luminance (cd / m ² ) from a surface light source. Furthermore, in equation (3), a specific position of the table surface and its extended surface is an origin p, an axis of coordinates in the left and right direction of the fuselage is x, an axis of coordinates in the direction longitudinal axis of the fuselage is u, and a coordinate axis in an up and down direction of the fuselage is h, as illustrated in Figure 17. In addition, in equation (3), an angle of the rectangular surface light source L is considered as being at x = 0, y = 0 and h = h. In other words, in equation (3), this angle of the rectangular surface light source L is considered to be directly above a position in which the illuminance is to be obtained.
[0167] However, as illustrated in Figure 19, in this embodiment, in positions a to f, which are positions on the table surface and on its extended surface, and in which the illuminance will be obtained, there is no angle of the surface light source directly above the positions. Therefore, the luminance E _h of each of the positions caf on the table surface is obtained using equation (4) mentioned below, and the luminance E _h of each of the positions a and b on the table surface and its extended surface is obtained using equation (5) mentioned below.
Eh = Ehi - Eh2 - Eh3 + Eh4 (4)
Eh = Ehi - E _h2 + Eh 3- E _h4 (5) [0168] In this case, equation (4) is an equation of when there is no source of superficial light in the y and y directions of the p position, in which the illuminance
37/48 will be obtained, as in the caf positions in Figure 19. That is, equation (4) is an equation of the state illustrated in Figure 18A. In addition, equation (5) is an equation of when there is no source of surface light in the x direction of position p, in which the illuminance will be obtained, as in positions a and b in Figure 19, but there is a source of surface light in the y direction. That is, equation (5) is an equation in the state illustrated in Figure 18B. In addition, E _h i indicates the illuminance of an origin p, when there is an angle of the virtual surface light source directly above a position (origin) p, in which the illuminance will be obtained, and there is, in a position 1, an angle of the virtual surface light source, located at a diagonal angle from that angle, and E _h 2 indicates illuminance of the source p, when there is an angle of the virtual surface light source directly above the source p, and there is, in a position 2 , an angle of the virtual surface light source located at a diagonal angle from that angle. Next, the same applies to E _h 3 θ E _h4 · In addition, the values of E _h i, Eh2, E _h3 θ E _h4 are all obtained using equation (3).
[0169] When the 10f organic EL lighting panel, having an external size of 10 x 30 cm ² and a luminance equal to or greater than 2,000 cd / m ² , described above, is used, the illuminance criterion mentioned above is substantially satisfied in all positions from a to d, as shown in Figure 19. However, the illuminance in the e and e positions, outside the table on its extended surface, exceeds the maximum illuminance criterion, defined in ARP 378. That is, when the lighting panel Organic EL 10f is used, the lateral scattering of the light increases.
[0170] Therefore, in this embodiment, the light shield plate 32 is provided at both the right and left ends of the EL organic lighting panel 10f, so that the lateral scattering of light from the EL organic lighting panel 10f can be eliminated . Specifically, when an oc angle of the light shield plate 32, with respect to the organic EL lighting panel 10f, is 45 ^Q , the illuminance in position f, outside the table on its extended surface,
38/48 is 16 Ix, which satisfies the initial illuminance criterion, defined in the ARP for that position f.
[0171] If the initial luminance of the EL organic 10f lighting panel is 2,000 cd / m ² , the life span of the EL organic 10f lighting panel is about 18,000 hours, when the EL organic 10b lighting panel is a neutral white type, and about 9,000 hours if the 10f organic EL lighting panel is a bulb color type. In this way, this EL organic 10f lighting panel is an alternative to a fluorescent lamp having a life span of around 10,000 hours.
[0172] As described above, in this embodiment, since the organic EL lighting panel 10b, having a thickness of 5 mm or less, is installed on the rear surface 83a of the backrest part 83 of the front seat, it is possible illuminate a passenger hand space by sitting on seat 81, without substantially reducing that hand space. Furthermore, in this embodiment, since the EL organic lighting panel 10f is installed in a position close to the passenger's hand space, it is possible to minimize the diffusion of light to the passenger by sitting on the adjacent seat 81. In addition, in this embodiment, since the light shield plate 32 is provided on the organic EL lighting panel 10f, it is possible to safely prevent light scattering for the passenger by sitting on the adjacent seat 81.
Seventh embodiment [0173] Next, a lighting device, according to a seventh embodiment of the present invention, will be described using Figure 20.
[0174] The lighting device of this embodiment includes an organic EL lighting panel, and a panel drive circuit, which drives that organic EL lighting panel, according to an instruction from a device
39/48 of control, similarly to all the embodiments described above. Even in this embodiment, the organic EL lighting panel and the panel drive circuit have the same structure as that shown in the first embodiment, or in its modification example.
[0175] In this embodiment, an organic EL lighting panel 10g is installed on the inner side of a shade shade 72, provided along a window 70, on its inner side 70, so that the transparent substrate 18 is directed inwards of the aircraft.
[0176] Eventually, in the AIR 512 described above, the illuminance in a seat space is defined as being equal to or greater than 53.82 Ix, when boarding, and equal to or greater than 21.53 Ix, during an overnight flight .
[0177] In this embodiment, to satisfy the illuminance criterion in a space 30 cm directly next to the shade 72, for example, the organic EL lighting panel 10g, having a luminance equal to or greater than 300 cd / m ² and an external size of 15 x 15 cm ² , was considered to be installed in shade 72. The luminance and external size of the EL organic lighting panel 10g, illustrated in this case, were obtained using equations (1) and ( 2) mentioned above. In addition, when the initial luminance is equal to 300 cd / m ² , the life span of the 10g organic EL lighting panel is equal to or greater than about 300,000 hours, regardless of the color temperature.
[0178] Generally, when direct sunlight is very strong, the passenger lowers the shade 72, However, in this case, the interior of the aircraft becomes very dark. In addition, when the shade 72 is lowered, the view from window 70 is prevented, and in this way, the passenger feels a little choking or little space. In this embodiment, since the 10g organic EL lighting panel, having a thickness equal to or less than 5 mm and emitting a light that is not very strong, is installed on the inner side of the shade 72, it is possible to prevent the side internal of
40/48 aircraft is very dark, without substantially reducing the internal space of window 70, even if the shade 72 is lowered when sunlight enters the aircraft. In addition, since the 10g organic EL lighting panel has a sense of depth when emitting light other than a fluorescent lamp, it is possible to prevent passengers from feeling suffocation or little space when the shade 72 is lowered .
[0179] In addition, it is preferable that the passenger's surroundings are dark, when the passenger lowers the shade 72 to sleep, and, therefore, that a key, to turn the 10g organic EL lighting panel on or off, be provided separately. In that case, it is preferable that the key is provided in the inner window frame element 71, covering the vicinity of the window 70, the armrest part 84 of the seat 81, or the like.
Example of modification of the seventh embodiment [0180] Next, an example of modification of the seventh embodiment, described above, will be described using Figure 21.
[0181] In the lighting device of this modification example, an organic 10H EL lighting panel is installed on an upper part of an inner window frame element 71 covering the vicinity of the window 70, so that a transparent substrate 18 is directed into the aircraft.
[0182] In this modification example, the organic EL lighting panel 10h is installed on top of the internal window frame element 71. Consequently, even if the shade 72 is lowered when sunlight enters the aircraft, it is It is possible to prevent the internal side of the aircraft from becoming too dark, without substantially reducing the internal space of the window 70, similarly to the seventh embodiment.
Eighth embodiment [0183] Next, a lighting device, according to the eighth
41/48 embodiment of the present invention, will be described using Figures 22 to 24.
[0184] The lighting device of this embodiment includes an organic EL lighting panel, and a panel drive circuit, which drives this organic EL lighting panel, according to a control device instruction, similarly to all the embodiments described above. Even in this embodiment, the organic EL lighting panel and the panel drive circuit have the same structure as that shown in the first embodiment, or in its modification example.
[0185] In this embodiment, an organic EL lighting panel 10i is installed on a mirror 100 of a washbasin, so that a transparent substrate 18 is directed in a direction in which the mirror 100 reflects light, that is, the internal part of the washbasin, as shown in Figure 22. This EL organic lighting panel 10i is installed in the respective positions on the right and left sides of an upper part and in the respective positions on the right and left sides of a lower part of the mirror 100. The lighting panels Organic EL 10i, installed on the top of the mirror 100, basically serve to illuminate a passenger face and its surroundings. On the other hand, the EL organic lighting panels 10i, installed at the bottom of the mirror 100, basically serve to illuminate the passenger's hands, a tap and its surroundings.
[0186] Mirror 100 is generally formed from a transparent plate 101, such as a transparent glass plate, and a reflection layer 102 applied to a surface of the transparent plate 101, as illustrated in Figures 23 and 24. The lighting panel Organic EL 10i can be installed on the side of the transparent plate 101, on which the reflection layer 102 is formed, as shown in Figure 23, or it can be installed on the side of the transparent plate 101, on which the reflection layer 102 is not formed. , as illustrated in Figure 24. However,
42/48 when the EL organic lighting panel 101 is installed on the side of the transparent plate 101, on which the reflection plate layer 102 is formed, it is necessary to prevent the reflection layer 102 from being between the transparent plate
101 and the EL organic lighting panel 101. Furthermore, regardless of whether the EL organic lighting panel 101 is installed on the side of the reflection layer
102 of the transparent plate 102 or on its opposite side, a recessed part can be formed on the installation side of the transparent plate 101, and the EL organic lighting panel 101 can be buried in the recessed part, or the EL organic lighting panel 101 can simply be glued to the installation side of the transparent plate 101.
[0187] Eventually, in the AIR 512 described above, the illuminance of a useful space in the sink is defined as 215.28 to 322.92 Ix.
[0188] In this embodiment, to satisfy the illuminance criterion in a space 50 cm under a panel installation position, for example, the organic EL lighting panel 101, having a luminance equal to or greater than 2,000 cd / m ² and a external size of 7.5 x 30 cm ² , was considered to be installed in mirror 100. The luminance and external size of the EL organic lighting panel 101, illustrated in this specification, were obtained using equations (1) and (2) presented above. In addition, if an initial luminance of the EL organic lighting panel 101 is 2,000 cd / m ² , the life span of the EL organic lighting panel 101 is around 18,000 hours, if the EL organic lighting panel 101 is a neutral white type, and about 9,000 hours if the organic EL lighting panel 101 is a bulb color type, as described above. Thus, this EL organic 101 lighting panel is an alternative to a fluorescent lamp having a life span of around 10,000 hours on an illuminance basis.
[0189] As described above, in this embodiment, since the panel of
43/48 EL organic lighting 101, having a thickness of 5 mm or less, is installed on mirror 100 in the washbasin, it is possible to sufficiently illuminate the useful space for hand washing, or similar, in the washbasin, without substantially reducing the useful space .
[0190] In addition, when three mirrors 100, 105 and 105 are installed in different directions in the sink, as shown in Figure 22, a depth of illumination is spread and the inside of the sink can be displayed in an excellent way.
[0191] Furthermore, in this embodiment, a sensor, which detects the presence of the passenger in the washbasin, can be provided, and a key, which causes the organic EL lighting panel 101 to be in a connected state, when the presence of the passenger in the lavatory is detected by this sensor, it can be provided.
Ninth embodiment [0192] In the following, a lighting device, according to a ninth embodiment of the present invention, will be described using Figure 25.
[0193] The lighting device of this embodiment includes an organic EL lighting panel, and a panel drive circuit, which drives that organic EL lighting panel, according to a control device instruction, similarly to all the embodiments described above. Even in this embodiment, the organic EL lighting panel and the panel drive circuit have the same structure as that shown in the first embodiment, or in its modification example.
[0194] In this embodiment, an organic EL lighting panel 10j is installed inside a small room 110 of an on-board kitchen, so that the transparent substrate 18 is directed inwards.
[0195] Eventually, in the AIR 512 described above, the illuminance on the platform
44/48 of luggage is defined as equal to or greater than 53.82 Ix, but the illuminance in the small room 110 of the on-board kitchen is not defined separately. However, it is preferable that the same illuminance on the luggage rack is guaranteed in an internal space of the small room 110 of the on-board kitchen.
[0196] As described above, in this embodiment, to satisfy the illuminance criterion in a space 30 cm from the EL organic lighting panel 10j, for example, the EL organic lighting panel 10j, having a luminance equal to or greater than 300 cd / m ² and an external size of 7.5 x 30 cm ² , was considered to be installed inside the small room 110. The luminance and external size of the EL organic lighting panel 10j, illustrated in this specification, were obtained by using equations (1) and (2) presented above. In addition, when an initial luminance is 300 cd / m ² , the life span of the 10j organic EL lighting panel is about 300,000 hours, regardless of the color temperature, as described above.
[0197] As described above, in this embodiment, once the organic EL lighting panel 10j, having a thickness of 5 mm or less, is installed inside the small room 110 of the on-board kitchen, it is possible to illuminate the internal part of the small room 110, without substantially reducing the internal space of small room 110. Therefore, in this embodiment, it is possible to improve visibility in small room 110 and increase the operational efficiency of the crew in the on-board kitchen.
[0198] Furthermore, in this embodiment, the organic EL lighting panel 10j can be connected, according to the opening and closing of door 111 of small room 110. In this case, it is preferable that the opening and closing of door 111 are detected by a key, and the organic EL lighting panel 10 is turned on when door 111 is opened and off when door 111 is closed.
45/48
Eleventh and eleventh embodiments [0199] Next, a lighting device, according to the eleventh and eleventh embodiments of the present invention, will be described using Figures 26 to 28.
[0200] The lighting device of the tenth and eleventh embodiments includes an organic EL lighting panel 10, and a panel drive circuit 30, which drives that organic EL lighting panel 10, according to an instruction from a lighting device. control 35, similarly to all of the embodiments described above.
[0201] The EL organic lighting panels 10m and 10n of the tenth and eleventh embodiments play a role as a signal light. Specifically, the EL organic lighting panel 10m from the tenth embodiment is installed inside the aircraft of a wall element 121, circling around an emergency exit 120, so that the transparent substrate 18 is directed towards the inside of the aircraft, as shown in Figure 26, and serves as a signal light indicating an emergency exit position 120. This EL organic 10m lighting panel is rectangular in shape, in which the words EMERGENCY EXIT are written. In addition, the EL organic lighting panel 10n of the eleventh embodiment is installed on a partition wall element 130, towards the cabin, so that the transparent substrate 18 is directed into the cabin, as shown in Figure 27, and it serves as a signal light indicating whether a washbasin is in use. This EL organic 10n lighting panel is circular in shape with an image of a person.
[0202] Therefore, it is preferable that the organic EL lighting panels 10m and 10n, which serve as the signaling light, have text and figure indicative of the content to inform passengers, depending on the content and in a way
46/48 dependent on the content such as the signal light.
[0203] In each of the 10m and 10n organic EL lighting panels of the tenth and eleventh embodiments, a sheet 25, with a figure or text indicating the content to be informed to passengers, is added to the EL organic lighting panel 10 ( Figure 4) of the first embodiment, as illustrated in Figure 28. for example, that sheet 25 is a transparent resin sheet and is bonded to the transparent substrate 18.
[0204] Eventually, in SAE Aerospace Recommended Aerospace Practice 503 (hereinafter ARP 503), mentioned above, the illuminance of a signal light in the vicinity of an emergency exit is defined as being 86 lx or greater, and the illuminance of the signal light in a partition between the cabins is defined as being equal to or greater than 1.3 Ix. Therefore, in the 10m and 10n organic EL lighting panels serving as the signal light, an initial luminance of around 100 cd / m ² is sufficient. In addition, when the initial luminance is equal to 300 cd / m ² , a life span of 10m and 10n organic EL lighting panels is equal to or greater than 300,000 hours, regardless of the color temperature, as described above.
[0205] As described above, in the tenth and eleventh embodiments, it is possible to make the organic EL lighting panels 10m and 10n function as the signal light, even when an installation space is not substantially guaranteed within a wall or in a space divided by that wall. In addition, the signal light is a source of surface light, and uniform luminance is required in the respective positions on the surface, in order to avoid non-recognition of information content for passengers. Since the 10m and 10n organic EL lighting panels, of the tenth and eleventh embodiments, meet these requirements, making the 10m and 10n organic EL lighting panels work as a signal light is very useful, as
47/48 in the tenth and eleventh embodiments.
[0206] Furthermore, since it is preferable for the signal light to be switched on, even during an emergency, when all of the aircraft's power supply fails, a light storage layer can be added to the organic EL lighting panel, as in the fourth embodiment described using Figure 12. Furthermore, the light storage layer can be added similarly to the organic EL lighting panels in the other embodiments.
[Industrial applicability] [0207] According to this lighting device, it is possible to illuminate the internal space of the fuselage, without substantially reducing the internal space of the fuselage.
