    LIGHTING DEVICE AND METHOD OF MANUFACTURING A LIGHTING DEVICE
    FIELD OF THE INVENTION
    The present invention relates, in general, to lighting devices and, more specifically, to a lighting device that comprises at least one light source to provide light arranged in an elongated hollow tubular member with a light-emitting surface for the light provided by the light source. The present invention also relates to a method of manufacturing such a lighting device.
    BACKGROUND OF THE INVENTION
    Recently, as lighting devices that comprise light emitting diodes (LEDs) are used as a replacement for traditional lighting devices such as conventional lamps, they also start being directed towards the application of fluorescent tubes. United States Patent No. 7,114,830 B2 describes this lighting device, which comprises an elongated hollow rigid tube in which several LEDs are inserted. The elongated hollow tube provides a light mixing chamber with a light output surface for light provided by the LEDs. The tube is rigid and typically made of glass or robust plastic, which limits the flexibility of manufacturing and installing the LEDs and other features of the lighting device in the tube. The lighting device is intended for use as a direct replacement for a conventional fluorescent lamp in a conventional fluorescent lighting installation.
    SUMMARY OF THE INVENTION
    It is the object of the present invention to provide an alternative and improved lighting device that can be manufactured and assembled flexibly and at low cost.
    According to a first aspect of the present invention,
    2/17 these and other objects are struck with a lighting device that comprises at least one light source to provide light and an elongated hollow tubular member. The light source is disposed within the tubular member and the tubular member comprises a light-emitting surface for light provided by the light source. The tubular member is formed by a set of at least partially flexible sheet comprising a base part which has an upper side on which the light source is arranged and at least a transparent or translucent part to provide the light output surface . The sheet assembly is adapted to be rolled into a tube in such a way that the light source is arranged inside the tube.
    In this way, a tube-shaped lighting device is provided that instantly provides the optical and mechanical properties necessary for easy assembly and the functionality of a light device. The tube formed by the flexible sheet assembly provides a light mixing chamber for light provided by the light source. The sheet assembly can be designed to provide the necessary stiffness and an appropriate thermal interface, for easy assembly, for example, with a transparent outer tube. The sheet assembly can be totally or partially flexible. This means that it can contain a rigid part around which the flexible part of the sheet assembly is folded to form the tubular member. Basically, all the necessary features for the lighting device can be integrated on the flexible sheet assembly. This can be conveniently accomplished using 2d processing methods with precise thickness control. In addition, as the light source is arranged inside the tube-shaped sheet assembly, the arrangement inherently provides electrical safety, as direct access to the source of light is avoided.
    3/17 light by a user.
    According to an embodiment of the lighting device, the lighting device additionally comprises a first optical layer arranged in the transparent part 5. The first layer is preferably supplied to the flexible sheet assembly in an uncoiled state, that is, while the sheet assembly is substantially arranged in the form of a flat sheet, which is advantageous. This allows for easier optical lamination or lamination of 10 larger surfaces that can be cut for later dimensioning. This is advantageous for the mass production of flexible sheet sets.
    According to an embodiment of the lighting device, the first optical layer is one of a diffusion layer 15 and a wavelength conversion layer, which is advantageous for providing a soft light emission or a desired wavelength of light from the lighting device. The diffusion layers and the wavelength conversion layers can be integrated into a film or 20 added in the form of separate films, or each can be added in several layers, allowing for diffusion or graduated light conversion capability. As mentioned above, the advantage of assembling film and sheet materials is ease of processing (2d) and is also very important for controlling thickness. The thickness of a wavelength conversion layer typically needs to be within +/- 2%, which is really difficult using other processes.
    According to an embodiment of the lighting device, the first optical layer is applied to the transparent or translucent part by means of lamination, deposition or in the volume of the transparent or translucent part by means of ‘extrusion or coextrusion, which is advantageous. It is still possible
    4/17 combine the diffusion functionality and conversion of wavelengths into one component.
    According to an embodiment of the lighting device, the transparent or translucent part is arranged in the form of a separate sheet which is interconnected to an end of the base part to form the flexible sheet assembly. This allows different optical properties for each part.
    According to an embodiment of the lighting device, the transparent or translucent part is additionally arranged with one of a diffuse surface, semitransparent film and reflection pattern, or which comprises diffuse or reflective particles. As an example, opaque particles with high reflection typically used in volume diffuser components can be integrated into the film. This allows the elaboration of the lighting distribution of the exit window and the reduction of the brightness of the LED source.
    According to an embodiment of the lighting device, the flexible sheet assembly additionally comprises a reflective layer disposed beside or near the light source. This increases the performance of the light source, that is, the lighting device, as no external reflector is needed. In addition, the light distribution of the lighting device can be designed to bring about higher efficiency in different applications. In addition, the reflective layer may comprise a heat dissipation functionality for thermal administration.
    According to an embodiment of the lighting device, the base part is reflective or incorporates a reflective functionality. This allows the use of fewer * components to form the lighting device, in
    5/17 compared to the addition of a reflective sheet on the transparent base.
    According to an embodiment of the lighting device, the base part is a sheet that is totally or partially transparent or translucent. This is advantageous if it is necessary to diffuse some light (such as to increase the cosmetic appearance of luminaires).
    According to an embodiment of the lighting device, the lighting device additionally comprises a transparent hollow outer body. The leaf assembly is disposed inside the outer body. In this embodiment, the flexible sheet set offers a pre-set in which all the necessary electrical and optical functionalities can be integrated into a sheet set that is advantageous from the manufacturing point of view and that can be easily assembled with the external body, such as a glass tube, for final assembly. The use of a glass tube then provides an additional layer of electronic insulation and mechanical protection for the lighting device. In addition, when providing, for example, a glass tube replacement, the appearance of the lighting device when it has a glass envelope increases the similarity of the product.
    According to an embodiment of the lighting device, the external body is arranged with a reflective part and / or a translucent part of diffusion, which can be advantageous from the cost point of view.
    According to an embodiment of the lighting device, the light source comprises at least one LED light emitting diode or LED mold.
    According to an embodiment of the lighting device, the external body is hermetically sealed after being evacuated, filled with gas or filled with liquid or
    6/17 solidifying material such as silicones. A controlled atmosphere inside the lighting device can be beneficial for the light source, such as the LED, and / or the performance of the wavelength conversion layer and / or service life. This can be achieved by providing, for example, a dry atmosphere, an inert atmosphere or a reactive atmosphere that eliminates oxygen.
    In accordance with a second aspect of the present invention, a method of manufacturing a lighting device is provided which comprises providing a set of at least partially flexible sheet by mounting at least one light source to an upper surface of a sheet. totally or partially flexible, which provides a transparent or translucent part for the flexible sheet, providing an optical layer for an upper surface of the transparent or translucent part and then wrapping the flexible sheet assembly in a tube, such that the light source is arranged inside the tube. The tube provides a light mixing chamber and the transparent or translucent part provides a light output surface from the tube for light provided by the light source.
    According to an embodiment of the method, the method additionally comprises closing the tube, in order to provide a closed tubular envelope that provides electronic insulation to living parts. By closing the tube, an independent lighting device is formed. The independent lighting device is also suitable for insertion into an external body, such as a glass tube as described above. The flexible sheet formed in a tube that is closed before insertion in the outer tube provides additional electronic insulation, which is advantageous in case of breakage of the outer tube.
    It is noted that the present invention relates to
    7/17 all possible combinations of the characteristics indicated in the claims.

    DETAILED DESCRIPTION
    A lighting device 101 according to the concept of the present invention is illustrated in Fig. 1a in an unrolled state. The lighting device comprises a sheet assembly 100 which is based on a carrier sheet
    8/17
    120 which, at present, is a transparent flexible sheet. The transparent carrier sheet is typically made of an appropriate polymer, which is either transparent or diffuse. In addition, the carrier sheet may be a stacked sheet, which comprises several layers. A light source 111, which at present comprises a linear set of light-emitting diodes (LED) for light generation, is arranged on an upper side 121 of the carrier sheet 120. The light source 111 is composed of a circuit board (PCB) with packaged LEDs. The light source 111 is attached to the carrier sheet 120 by means of an adhesive, such as silicone or a two-component thermal compound. Any suitable adhesive, which preferably has good thermal conductivity, is applicable. Alternatively, the light source can be fixed by means of mechanical fixation such as a coiled spring. Appropriate electrical connection means (not shown) for the light sources are provided at the ends of the assembly, either in the form of an electrical connector on the PCB or as a welding pad. The electrical connection means are additionally arranged to be electrically connected for individual application to an applicable energy source.
    With the light source 111 in place, the lighting device 100 is wrapped around a tube, that is, an elongated hollow tubular member, as shown in Fig. 1b. To fix the tube shape, the ends of the carrier sheet 120 that come into contact with each other as the tube is formed are glued together or welded along the tube.
    Alternatively, the tube shape can be maintained, for example, by arranging supports such as rings on the end parts of the tube (not shown) or clamps on the end parts of the tube (not shown). The sheet assembly can also be rolled up and attached to the
    9/17 final rigid shape, with the two sides fixed together to form a rigid tube before its insertion in an external body, as will be described below. In this case, the rigid tube can be folded and unfolded in a certain area before and after insertion, respectively.
    By fixing the tube shape, an independent lighting device 100 is formed. The rigidity of the carrier sheet 120 is preferably selected in such a way that the lighting device 101 has sufficient mechanical properties for handling and providing protection of the electronic circuit contained in the inside the tube.
    As explained above, carrier sheet 120 is the basis of a sheet assembly that is adapted for winding in a tube. The need for the sheet assembly to be rolled into a tube indicates that it is at least partially flexible so that a portion of it can be rolled up to allow the sheet assembly to form a hollow tube. One possible solution, for example, is that a base part, which is defined as the part of the sheet set on which the light source is placed, is rigid, while the transparent part is flexible, so that it can be rolled up. on the base part. The opposite is also applicable, that is, that base part is flexible while the transparent part is rigid.
    The sheet set is based on the present on a single carrier sheet. The sheet assembly may, however, be a stack of several sheets. In alternative embodiments (not shown), different optical properties are provided on each side of the carrier sheet. The carrier sheet can be, for example, partially white on the upper side 121 and partially black on the lower side. In addition, the carrier sheet can contain text, such as the
    10/17 company logo, technical data and alignment markers to facilitate additional processing during the manufacture of the lighting device. The carrier sheet can be reflective or even absorbent. Additionally, the carrier sheet can be equipped directly with an electrically conductive surface or electrically conductive tracks to supply electrical energy to the light sources.
    The light source 111 on the upper side 121 of the carrier sheet 120 is disposed within the tube formed by the sheet assembly. The tube provides a light mixing chamber for light provided by the light source 111. A transparent part 122 which, at present, is a part of the transparent carrier sheet 120 is arranged on an opposite side of the tube with respect to the light source 111 The transparent (or, alternatively, translucent) part 120 provides a light-emitting surface of the tube.
    In one embodiment of the lighting device 201, see Fig. 2, the sheet assembly 200 comprises a carrier sheet 220. The upper side 221 of the carrier sheet 220 is arranged with conductive tracks of electricity (not shown) to which a light source 211. Light source 221 comprises white LEDs. In addition, a transparent part 222 disposed on the side of the base part of the carrier sheet 220 has an optical layer 230 disposed on the top side 221. The optical layer 230 is a white diffuse film applied to the carrier sheet 220 by means of lamination. The color of the diffuse film can be selected for each individual application of the lighting device. In Fig. 2b, the sheet assembly 200 is rolled up in a tube, such that the light source 211 is arranged inside the tube and is in the opposite position to the transparent part 222 with the diffusing layer 230. In this realization of the device
    11/17 lighting, the sheet assembly 200 is additionally inserted into a transparent hollow outer body, a glass tube 24 0, see Fig. 2c. The outer body can also be made of a suitable transparent polymer material. Preferably, the outer body is dimensioned to match the size of the tube formed by the sheet assembly 200, both in terms of the diameter of the tube and the length of the tube.
    sheet assembly 200 is arranged to expand diametrically after insertion into the outer glass tube 240 due to its own elastic strength, in order to achieve good contact with the inner wall of the glass tube 240.
    In one embodiment, the sheet assembly is glued to the inner surface of the outer body. The glue can be selected to increase the heat transfer of the lighting device or be selected with an adapted refractive index to reduce Fresnel reflection.
    Alternatively, the leaf assembly is assembled, for example, with coiled springs or with solid shapes (not shown) that support the leaf assembly in the desired shape. Solid forms may have additional functionality such as electrical contact between the carrier sheet and the lamp covers.
    When inserting the rolled sheet assembly into an outer body, fixing the tube shape of the sheet assembly is no longer necessary. However, it may be advantageous to secure the sheet assembly so that it is an independent unit for a few different reasons. First, the independent closed sheet assembly provides additional security in the event of a breakdown of the outer body. The closed sheet assembly provides an insulation conductor and any electrical wires inside the sheet assembly can be considered double insulated by the outer body and the sheet assembly
    12/17 closed. In this way, in case of breakage of the external body, such as an external glass tube, the closed sheet assembly still guarantees safety. The need for drivers isolated from the power grid can then be less. In addition, the leaf assembly can be closed on itself to simplify assembly with an external tube or to prevent the carrier leaf from bending over the life of the lamp.
    An additional advantage of the concept of the present invention is the fact that disassembly at the end of life becomes easier, as the outer body can be recycled after removing the sheet assembly.
    The assembly of a lighting device 301 according to the concept of the present invention is described below with reference to Figs. 3a and 3b. A transparent carrier sheet 320 is provided first. A base portion of the carrier sheet is designed to guide the light source of the device. A phosphorous material 330 is deposited on approximately half of the upper surface of the carrier sheet 320, where that part is intended to be the light output of the lighting device 301. The phosphorous material is a wavelength conversion material used in combination with LEDs to produce visible light. This is known to those skilled in the art and will not be discussed further in the present. An adhesive, preferably filling spaces, 350 is applied to the base part on the upper surface of the carrier sheet 320, where that adhesive is used to fix a light source 311, a blue LED on a PCB, to the carrier sheet 320. The adhesive is selected to ensure a good thermal and mechanical connection from the PCB to the carrier sheet 320. The PCB, in this embodiment, is a metal core PCB (MC), but any suitable type is applicable. A high-reflection white mask 360 is added to light source 311 that substantially covers the
    13/17 base part of the carrier sheet 320. In addition, the mask 3 60 is adapted in such a way that only the blue LED is exposed upwards in relation to the upper surface of the carrier sheet 311, that is, the PCB and the adhesive the light sheet is covered. The reflective mask 360 is, at present, a self-adhesive sheet. The reflective mask 360 is advantageous for masking parts of the light source that do not need to be exposed, for example, when the light source is a set of LEDs arranged on a relatively wide front panel or PCB, which is applicable to increase the surface of heat trap of the light source. In addition, if, for example, silicone glue is used to fix the light source to the carrier sheet, any excess dosage of silicone can flow under the mask, where it is kept for further curing.
    In Fig. 3b, the sheet set 300 formed by the carrier sheet 320, the light source 311, the phosphor layer 330 and the reflective mask 360 was rolled into a tube and inserted into a glass tube 340. The ends of the sheet carrier 320 that come into contact with each other as the tube is formed are not fixed to each other at present. When the mask 360 is a self-adhesive sheet, it can, in alternative embodiments, be used to also fix the tube shape, when it is dimensioned to overlap the ends of the carrier sheet that come into contact with each other.
    An embodiment of a lighting device 401 in accordance with the concept of the present invention and an alternative way of manufacturing the lighting device are illustrated with reference to Figs. 4a and 4b. At this point, a light source 411, which comprises a blue LED, is fixed directly to an opaque sheet 420, which integrates the optical reflector functionality, which was introduced by
    14/17 white reflective mask in the example above, on the carrier sheet itself. The opaque sheet 420 may be a metallic sheet, such as Al, and is preferably selected to provide sufficiently high light reflection capability in the blue spectrum (when using a blue light source). A separate transparent carrier sheet 422 is equipped with a wavelength conversion sheet 430 over the entire length by lamination.
    The separate transparent carrier sheet or the transparent part of a common carrier sheet is, in alternative embodiments, equipped with the phosphorous material or a different or additional optical layer such as a diffusing surface, a semitransparent film, a reflective pattern etc. through deposition, lamination, extrusion or co-extrusion according to methods known in the field. In this way, several different optical features can be conveniently integrated into the sheet set. It is a specific advantage to provide the optical layers on a flat film because it allows the deposition of wavelength conversion material such as inorganic matches or organic matches or quantum dots with high control of thickness and uniformity. The wavelength conversion layers or other optical layers can be deposited in a single layer, in multiple layers or in mixed layers. The combination of a wavelength conversion sheet and a semitransparent sheet or reflector pattern can be used to control the intensity of light emission from the lighting device and to locally regulate the luminescence of the lighting device. You can also use a semitransparent sheet without adding a wavelength conversion material.
    The transparent carrier sheet 422 and the opaque sheet 420 are then interconnected by means of a joint
    15/17 welded to form a sheet assembly. Alternatively, the interconnection is provided by means of an adhesive, tape or other suitable means.
    The sheet assembly 400 is formed in a tube which is inserted into an external glass tube 440, see Fig. 4b. As shown in Fig. 4b, the tube is closed, that is, the transparent carrier sheet 422 and the opaque carrier sheet 42 0 are interconnected by means of welded joints on each end, forming longitudinal connections, which are strong enough to provide electrical security if the glass tube breaks.
    The interconnection between separate carrier sheets can alternatively be provided by welding at points of several marked flexible sheets stacked.
    In one embodiment of the lighting device 501 as described with reference to Figs. 5a and 5b, instead of using LEDs over an interconnect, molds 513 are arranged on a track of conductive wires 512 and equipped with a protective silicone dome 511. The resulting light source subset 514 is glued onto a transparent carrier sheet 520 with an adhesive 550. The carrier sheet 520 is equipped with a phosphorous material 530 as described above. The resulting sheet set 50 0 is rolled into a tube and inserted into an outer tube 54 0, which is a TLD Reflex 54 0 tube, that is, a glass tube that is arranged with a reflective layer typically provided in circumference around half of its inner surface 541 along the tube and which has a transparent surface 542 on the opposite half. The coiled tube is positioned in such a way that the light source 514 is arranged on that reflecting surface of the outer tube 540.
    The insertion of the carrier sheet in an external body can be carried out in different ways. An effective way
    16/17 of inserting a carrier sheet in an external body according to the concept of the present invention is to make use of a Teflon insertion sheet. The sheet set is placed over the insertion sheet. The sheet assembly and the insertion sheet are then made up into a roll or tube and inserted into the outer body. The insertion sheet is then extracted again, allowing the accommodation of the sheet assembly inside the outer body. If the sheet set is closed on itself, it can be inserted without an insert sheet, for example, by sliding or blowing into the external body.
    In some embodiments, after mounting the leaf assembly and the outer body, the cavity of the lighting device is evacuated or filled with a gas and sealed. Alternatively, the cavity of the lighting device can be filled with a liquid or solidifying material, such as silicones.
    The outer body can be cylindrical, but other tubular shapes are possible. In Fig. 6, an elliptical cross section of the outer body 640 is illustrated. By providing a flexible but still elastic carrier sheet, the sheet assembly 600 will adapt to the shape of the outer body 640. In addition, as illustrated in the device of Fig. 6, the set of LEDs does not necessarily have to be an isolated line over the LEDs. Several lines of 611 LED sets are displayed, with significant distance between them. The elliptical cross section of the lighting device 601 is advantageous at present to provide low luminescence and reduced brightness.
    Alternatively, the linear assembly may consist of a PCB with chip LEDs or it may be a linear front frame with LED molds and wired joints that can be additionally overmoulded with silicone locally or
    17/17 along the entire length. LEDs or LED molds can be combined with wavelength conversion material. The linear assembly can also be based on a sheet with an electrically conductive surface. LEDs in a linear array are suitable for the concept of the present invention, but other provisions also apply. The linear assembly, in embodiments of the present invention, is equipped with separate lenses or a common linear lens.
    In addition, in alternative embodiments of the lighting device, the light sources can be combined with light sources arranged on the inner side of the external body (not shown). The construction of the light sources on the side of the transparent hollow outer body can be a part of the leaf assembly, but they can alternatively be separate light sources or be integrated with other parts such as lamp covers. You can add LEDs on the side for decorative purposes, accent lighting or, for example, a night light. For these purposes, the LEDs on the side can be equipped with separate connections and the directives to the mains.
    Those skilled in the art understand that the present invention is in no way limited to the preferred embodiments described above. On the contrary, many modifications and variations are possible within the scope of the attached claims.
