    [0001] This paper relates to a flashing light.
    [0002] As disclosed in Japanese Patent Laid-open Publication No. 2003312359a, a flashing light has been proposed in which an outside mirror is removed and a camera capable of acquiring an image towards the rear of a vehicle is mounted in place of the flashing light. The inventors have planned to improve the visibility of such a flashing light by installing a light guide in the flashing light. However, when the camera and the light guide are mounted in the flashing light, the flashing light is enlarged so that the aerodynamic drag of the vehicle can increase. Accordingly, it is an object of this disclosure to provide a flashing light that includes a camera and a light guide and avoids increasing aerodynamic drag. According to the present disclosure, a flashing light comprises: a body of fire; an outer cover that forms a fire chamber with the body of fire; a light source installed inside the fire chamber; a light guide installed within the fire chamber and configured to guide light emitted from the light source; and a camera installed inside the fire chamber and including an image capture device. When the flashing light is attached to a vehicle surface, at least a portion of the light guide is formed in an area extending from the camera in a direction following a vehicle surface. In a case where a flashing light is mounted on a vehicle, and the flashing light greatly exceeds the vehicle surface, the aerodynamic drag of the vehicle increases, or the aesthetic character of the vehicle is degraded. However, it has been found that, even if the flashing light is slightly enlarged in a direction following a vehicle surface, the flashing light may barely protrude from the vehicle surface so that the aerodynamic drag can hardly be increased. In addition, the flashing light can hardly degrade the aesthetic character of the vehicle.
    [0003] When a flashing light element is disposed in the area extending from the camera in the direction following the vehicle surface, the flashing light may barely be enlarged in a direction in which the flashing light is protruding from the vehicle surface . Therefore, the increase in aerodynamic drag by the flashing light can be avoided by arranging the light guide of the area extending from the camera in the direction that follows the vehicle surface. In the flashing light, the light guide may comprise: a thick portion, at least a portion of which is formed in an area extending from the camera in the direction following the vehicle surface as well as in at least one one direction up and one direction down when the flashing light is attached to the vehicle; and a thin portion, at least a portion of which is formed in an area extending from the camera in a forward and a backward direction. The thin part is thinner than the thick part. Since the large light guide which includes the thick portion and the thin portion may be located in the fire chamber using the area extending from the camera in the direction following the vehicle surface and in at least one from the upward direction and the downward direction as well as an area that extends from the camera in the fore-aft direction, the visibility can be further improved while avoiding to enlarge the flashing light in the direction wherein the flashing light is protruding from the vehicle surface. In the flashing light, the thick portion and the thin portion may be formed integrally with each other. Since the thick part and the thin part can be illuminated by a single source of light, the magnification of the flashing light can be avoided while improving the visibility. The flashing light may further include an extension installed in the fire chamber, and configured to protect at least a portion of an interior surface of the fire body, the light source, the light guide, or the camera of the outside. An image capture device cache portion may be disposed on the extension to prevent light emitted from the light guide or the light source from being introduced into the image capture device. Since the light emitted from the light source does not enter directly or indirectly into the image capture device, the image information can be acquired in a good manner. In the flashing light, the extension may include in one piece a camera cover portion that protects the camera except for the image capture device from the outside.
    [0004] In the flashing light, the extension may comprise in one piece a light source cover portion which protects the light source from the outside.
    [0005] According to the present disclosure, a flashing light is provided which includes a camera and a light guide and avoids the increase of the aerodynamic drag.

A pair of left and right flashing lights 10 is installed on a surface on the right side and a surface on the left side of the vehicle. 1, respectively. The vehicle 1 illustrated in FIG. 1 does not include a wing mirror or a door mirror. The observation function of the rear side, which is provided by the wing mirror or the door mirror, is performed by a camera 50 installed in the flashing light 10 which will be described below. The right flashing light, which is installed on the surface of the right side of the vehicle 1, includes a straight camera on the inside. The left flashing light, which is installed on the surface of the left side of vehicle 1, includes a left camera inside. Each of the right camera and the left camera acquires image information about the rear of the vehicle 1.
    [0008] Figure 2 is a block diagram of the right flashing light and the left flashing light. As illustrated in FIG. 2, the vehicle 1 comprises an electrical control unit 5 connected to a right camera 50R and to a left camera 50L. The vehicle 1 comprises a right camera control screen 6 and a left camera control screen 7, which are connected to the electrical control unit 5 in a vehicle compartment. The right camera 50R and the left camera 50L transmit acquired image information to the electrical control unit 5.

The right camera control screen 6 displays the image information acquired by the right camera 50R. The electrical control unit 5 transmits the acquired image information from the left camera 50L to the left camera control screen 7. The left camera control screen 7 displays the image information acquired by the camera. left camera 50L. For example, the left camera control screen 7 displays an image shown in FIG. 3. On the other hand, the right camera control screen 6 and the left camera control screen 7 may be control screens which are independent of each other. Alternatively, the right camera control screen 6 and the left camera control screen 7 may be a single, common control screen, and the single control screen may be divided into left and right parts so as to allow on the control screen to display the image from the right camera 50R and the image from the left camera 50L. The flashing light 10 according to the first exemplary embodiment of the present disclosure will then be described in detail.
    [0009] Moreover, FIG. 4 in FIGS. 13A and 13B illustrate the right flashing light. Since the left flashing light and the right flashing light have the same configuration, only the right flashing light will be described. In the following description, the right flashing light is simply called flashing light unless otherwise specified. In addition, in the following description, a top-bottom direction, a left-right direction, and a front-back direction refer to directions in the case where the flashing light is seen from the driver in a state where the The flashing light 10 is attached to the vehicle 1. Figure 4 is a side view of the flashing light 10 according to the first exemplary embodiment of this disclosure. FIG. 5 is an exploded perspective view of the flashing light 10 illustrated in FIG. 4. As illustrated in FIGS. 4 and 5, the flashing light 10 comprises a fire body 11, an outer cover 12, a light-emitting diode (FIG. LED) 20 (an example of a light source), a light guide 30, an extension 40, and a camera 50. A fire chamber S (see FIG. 7) is formed by the fire body 11 and the outer cover 12. The light-emitting diode 20, the light guide 30, the extension 40 and the camera 50 are installed in the fire chamber S. The light-emitting diode 20 is mounted on a mounting substrate 21. The light-emitting diode 20 is fixed on the fire body 11 through the mounting substrate 21. Although an example in which the light-emitting diode 20 is used as the light source has been described in the present exemplary embodiment, for example, a light bulb filament, a discharge lamp, an organic electroluminescent device (EL), or a laser diode (LD) can be used as the light source, instead of the light emitting diode 20. The light guide 30 is a transparent resin element which guides the light emitted by the light-emitting diode 20. The light guide 30 is a U-shaped element rotated 90 ° in a side view. The light guide 30 is fixed on the mounting substrate 21 of the light-emitting diode 20 in an orientation where the lower part 30a of the letter U is directed towards the front part of the vehicle 1.
    [0010] The light guide 30 includes an incidence portion 31, a main light guide portion 32 (an example of a thick portion), and a light guide portion 33 (an example of a thin portion) of one piece. The incidence portion 31 is connected to the lower portion 30a of the letter U, and covers the light emitting diode 20. The main light guiding portion 32 has a forked shape which is divided from the lower portion 30a of the letter U at upper and lower portions along the outer edge of the letter U. Rear end portions 34 of the light guide 30 are formed at rear ends of the main light guiding portion 32. rear end 34 has a rear end surface, the normal direction of which extends rearwardly. The secondary light guiding portion 33 is formed between the upper portion of the main light guiding portion 32 and the lower portion of the main light guiding portion 32. The thickness of the secondary light guiding portion 33 in FIG. the left-right direction is smaller than the thickness of the main light-guiding portion 32 in the left-right direction. On the other hand, at least one of a slightly concave portion 33a or a slightly convex portion 33a may be formed on at least one of the surface of the secondary light guide portion 33 at the outer cover side 12 and the surface of the outer cover 12 at the secondary light guide portion side 33. The light guided from the secondary light guide portion 33 may be reflected to a lateral side of the vehicle by the slightly concave portion 33a or the slightly convex 33a. With this, the visibility of the flashing light 10 from the side of the vehicle can be improved. The light emitted from the light-emitting diode 20 is introduced into the incidence portion 31 of the light guide 30. Part of the light introduced into the incidence portion 31 is emitted from a surface of the light-guiding portion main 32, and the remainder is guided to the rear end portions 34 to be emitted backward from the rear end portions 34. A law-prescribed light distribution pattern is formed by the light emitted from the rear end portions 34. In addition, a portion of the light introduced into the incidence portion 31 is also guided to the secondary light guiding portion 33 to be emitted from the surface of the portion of the Secondary light guidance 33. As described above, the flashing light 10 improves visibility by bringing the main light guiding portion 32 and the secondary light guiding portion 33 to emit light while forming the law-prescribed light distribution pattern by light emitted from the rear end portions 34.
    [0011] In this exemplary embodiment, the light emitting diode 20 emits white light. The light guide 30 is orange. The outer cover 12 is colorless and transparent. When the light-emitting diode 20 is turned on, the light guide 30 is tinted in orange, thus functioning as a flashing light. The extension 40 is an element which protects at least a portion of an element disposed on an inner surface of the light guide. body of fire 11 or inside the fire chamber S from the outside. On the other hand, the inner surface of the fire body 11 relates to the surface on the forming side of the fire chamber S. In the present exemplary embodiment, the element disposed within the chamber of fire light S indicates at least one of the light-emitting diode 20, the light guide 30, and the camera 50. The extension 40 comprises a frame portion 41 which has a shape which follows an outer edge of the fire body 11, a a camera cache portion 42 which covers the camera 50, a light source cache portion 43 which protects the light emitting diode 20 from the outside, and a light transmitting portion 45. The front end of the cache portion camera 42 has a shape corresponding to the rear end of the secondary light guide portion 33 of the light guide 30. In this manner, the extension 40 and the light guide 30 give an impression of a single body, which improves the design.
    [0012] The light source cover portion 43 covers the light emitting diode 20 from outside the incident portion 31 of the light guide 30. As a result, the light source cover portion 43 protects the light source emitting light from the light-emitting diode in the form of dots on the light guide 30 from the outside, thus improving the appearance. The light transmitting portion 45 transmits light directed from the surface of the main light guiding portion 32 or the surface of the secondary light guiding portion 33 to the lateral side of the vehicle. The light transmitting portion 45 may be configured as an opening or a transparent area using a transparent material.
    [0013] The camera 50 includes an image pickup device 51, and a support substrate 52 that supports the image pickup device 51. The camera 50 is attached to the fire body 11 in an orientation in which the direction of capture image of the image capture device 51 is directed rearwardly. The camera 50 is installed behind the light emitting diode 20. The camera 50 is installed at the rear end between the upper portion of the main light guiding portion 32 and the lower portion of the main guiding portion 32 of the light guide 30. The image capture device 51 is located between the upper rear end portion 34 and the lower rear end portion 34 of the light guide 30. The image capture device 51 of the camera 50 is exposed to the rear from the rear end of the camera cache portion 42. The power supply of the camera 50 is implemented by a power line (not shown) extending, for example, from the unit. electrical control 5 (see, for example, Figure 2) of the vehicle. The camera 50 transmits image capture data to the electrical control unit 5 via a transmission line (not shown).
    [0014] Fig. 6 is a perspective view illustrating the flashing light 10 illustrated in Fig. 4 in a state in which the outer cover 12 is removed. As shown in FIG. 6, in the flashing light 10 according to the present exemplary embodiment, the upper rear end portion 34 of the light guide 30 is located behind the lower rear end portion 34. virtual line E is a virtual line extending in the vertical direction through the rear end of the upper rear end portion 34. The image capture device 51 of the camera 50 is behind the virtual line E. That is, the image pickup device 51 is behind the rear end portion 34 of the light guide 30. As a result, the rear end portions 34 of the light guide 30 are not included in a viewing angle of the image pickup device 51 so that the image pickup device 51 can acquire good image information.
    [0015] Fig. 7 is a sectional view taken along the line VII-VII of Fig. 4. As shown in Fig. 7, the extension 40 includes a pair of upper and lower image capture device cache portions 44 , whose perpendicular extends in the downward direction. The image capture device cache portions 44 are installed between the upper rear end portion 34 of the light guide 30 and the image capture device 51 of the camera 50 and between the lower rear end portion. 34 of the light guide 30 and the image capture device 51 of the camera 50, respectively. The image capture device cache portions 44 block the light that is emitted from the rear end portions 34 of the light guide 30 and introduced into the image capture device 51. With this, the device image capture 51 can acquire good image information. <Active Effect> As illustrated in Fig. 7, in the present exemplary embodiment, the surface of the front fender 4 (an example of the vehicle surface), on which the flashing lights 10 are attached, is inclined with respect to the vertical direction. In Fig. 7, a virtual line C is a line extending in a direction following the surface of the front wing 4 through the left end of the camera 50. A virtual line D is a line extending in the direction that follows the surface of the front wing 4 through the right end of the camera 50. A virtual line A is a line extending in a direction perpendicular to the virtual line C through the upper end of the camera 50. A virtual line B is a line extending in the direction perpendicular to the virtual line C through the lower end of the camera 50. The area between the virtual line C and the virtual line D is an area which is extends from the camera 50 in the direction that follows the surface of the front fender 4. The area between the virtual line A and the virtual line B is an area that extends in a direction that exceeds the surface of the front wing 4 because of the camera 50. Moreover , the virtual lines A, B, C and D are lines that pass through the four corners of the support substrate 52 of the camera 50, respectively. In Figure 7, however, the virtual lines A to D are drawn as if they did not pass through the four corners of the support substrate 52 of the camera 50 to make the figure easy to see. As illustrated in FIG. 7, when the flashing light 10 is attached to the vehicle 1, the upper rear end portion 34 of the light guide 30 is formed in a space above the camera 50 between the virtual line. C and the virtual line D, and the lower rear end portion 34 of the light guide 30 is formed in a space below the camera 50 between the virtual line C and the virtual line D. That is, say that the upper and lower rear end portions 34 of the light guide 30 are formed in an area extending from the camera 50 in the direction following the surface of the front wing 4.
    [0016] When the relatively large light guide 30 is installed inside the fire chamber S as in the flashing light 10 according to the present exemplary embodiment, a light emitting area is increased, which can improve the visibility. However, when the camera 50 is to be installed inside the fire chamber S in addition to the large light guide 30, the flashing light 10 may be enlarged to accept them. In a case where the flashing light 10 is mounted in the vehicle 1, the aerodynamic drag of the vehicle 1 is increased or the aesthetic character of the vehicle is degraded when the flashing light 10 greatly exceeds the surface of the front wing 4.
    [0017] However, the inventors who have made this presentation have found that the aerodynamic drag is barely increased, and moreover, the aesthetic character of the vehicle 1 is hardly degraded, even if the flashing light 10 is relatively enlarged in the following direction the front wing surface 4. Thus, with the flashing light 10 according to the present exemplary embodiment, the light guide 30 is disposed in the area extending from the camera 50 in the direction following the front wing surface 4. When at least a portion of the light guide 30 is disposed in the area extending from the camera 50 in the direction following the surface of the front wing 4, the flashing light 10, which includes the camera 50 and the light guide 30, is barely increased in size in the direction in which the flashing light 10 protrudes from the surface of the front fender 4. Therefore, said blinker light 10, which includes the guide of light of g size 30 and the camera 50, has a high visibility, and avoids the increase in aerodynamic drag.
    [0018] As shown in FIG. 6, in the flashing light 10 according to the present exemplary embodiment, at least a portion of the main light guiding portion 32 of the light guide 30 is formed in the area which extends from the camera 50 in the direction that follows the surface of the front wing 4 and also in at least one of the upward direction and the downward direction when the flashing light 10 is attached to the vehicle 1. From further, at least a portion of the secondary light guide portion 33 of the light guide 30 is formed in the area extending from the camera 50 in the fore-and-aft direction when the flashing light 10 is attached to the vehicle 1 That is, the large light guide 30, which includes the main light guide portion 32 and the secondary light guide portion 33, is within the fire chamber S , using the area that extends from the cam ra 50 in the direction following the surface of the front wing 4 and also in at least one of the upward and downward direction and the area extending from the camera 50 in the forward direction. back. Since no large portion is present in any single area, it is possible to limit an increase in the overall size of the flashing light 10. Therefore, through the use of the large light guide 30, the visibility is further increased while the magnification of the flashing light 10 is suppressed in the direction where the flashing light is protruding from the surface of the front wing 4. In addition, the "area extending from the camera 50 in at least one of the upward direction and the downward direction, "mentioned here, is a concept that includes an area that extends from the camera 50 in the vertical direction as well as an area that extends from the camera 50 in a direction having an acute angle of 0 to 30 degrees with respect to the vertical direction. Further, in the flashing light 10 according to the present exemplary embodiment, the extension 40 includes the image capture device cache portions 44, which prevent light emitted from the end portion 34 of the light guide 30 to be introduced into the image capture device 51 of the camera 50. The camera 50 can acquire good image information because the light emitted from the light emitting diode 20 not directly or indirectly into the light-emitting element 51, by virtue of the image-capture-device cache portions 44. In the flashing light 10 according to the present exemplary embodiment, the guide portion main light 32 and the secondary light guide portion 33 are formed integrally with each other. Therefore, the main light guiding portion 32 and the secondary light guiding portion 33 can be illuminated simultaneously by the single light emitting diode 20 such that the magnification of the flashing light 10 is avoided while improving visibility. On the other hand, for example, the shape of the light guide 30, the shape of the camera 50, or the positional relationship between the light guide 30 and the camera 50 are not limited to the exemplary embodiment described herein. -above. Thus, flashing lights 10A through 10E according to second to sixth exemplary embodiments of the present disclosure will be described. The same components as those in the flashing light 10 according to the first exemplary embodiment are designated by the same references, and the descriptions thereof will be omitted. <Second exemplary embodiment> Fig. 8 is an exploded perspective view of the flashing light 10A according to the second exemplary embodiment of this disclosure. As illustrated in FIG. 8, the flashing light 10A according to the present exemplary embodiment is different from the first exemplary embodiment in terms of the shape of a light guide 30A. The light guide 30A does not include a secondary light guide portion. The flashing light 10A according to the present exemplary embodiment can allow the main light guiding portion 32A to emit more brilliant light because the main light guiding portion 32A can be illuminated with light. the light that would otherwise be used to illuminate the secondary light guide portion 33 in the flashing light 10 according to the first exemplary embodiment.
    [0019] Even in this exemplary embodiment, the light guide 30A is in the area extending from the camera 50 in the direction that follows the surface of the front fender 4. Therefore, the increase in the aerodynamic drag caused by the flashing light 10A is avoided while improving visibility. <Third Exemplary Embodiment> Fig. 9 is an exploded perspective view of the flashing light 10B according to the third exemplary embodiment of this disclosure. As illustrated in FIG. 9, the flashing light 10B according to the present exemplary embodiment is different from the first exemplary embodiment in terms of the shape of a fire body 10E, a light guide. light 30B, an extension 40B, and the outer cover 12.

The secondary light guiding portion 333 is a plate-shaped area that extends downward from the main light guiding portion 32B. The secondary light guide portion 33B is formed with a slot extending in the up-down direction. The thickness of the secondary light guide portion 33E in the left-right direction is smaller than the thickness of the main light guide portion 32E in the left-right direction. In this exemplary embodiment, as illustrated in FIG. 9, the camera 50 includes a light shielding member 54 made of an opaque material. The light shielding member 54 is installed between the rear end portion 34B of the light guide 30E and the image pickup device 51.

Furthermore, in a case where the rear end portions 34A of the light guide 30A are located above and below the capture device Fig. 51 as illustrated in Fig. 8, a cylindrical light shielding member configured to surround the image pickup device 51 may be used, and light shielding elements may be used. They must be installed above and below the image capture device 51, respectively. In addition, three or more light shielding elements can be provided. The extension 403 includes a frame portion 41E that has a shape that follows the outer edge of the fire body 11B, and a camera cache portion 42B that covers a portion of the camera 50. The camera cache portion 42B protects the support substrate 52 of the camera 50 from the outside and exposes the image capture device 51 to the rear. Of the inner surfaces of the light body 118, the surface facing the secondary light guide portion 33E of the light guide 30B is formed with a deposited metal film 111E. The light emitted from the secondary light guide portion 33B to the fire body 11B is reflected by the deposited metal film 111B and is emitted externally through the light guide 308. Light utilization efficiency is increased, and the visibility of the flashing light 10E is improved. Even in this exemplary embodiment, the rear end portion 343 of the light guide 30B is formed above the camera 50, and the light guide 30B is in the area extending from the camera 50 in the direction that follows the surface of the front wing 4. Therefore, the increase in aerodynamic drag caused by the flashing light 10B is avoided while improving visibility. <Fourth Exemplary Embodiment> Fig. 10 is an exploded perspective view of the flashing light 10C according to the fourth exemplary embodiment of this disclosure. As illustrated in Fig. 10, the flashing light 10C according to the present exemplary embodiment is different from the third exemplary embodiment in that the second main light guiding portion 350 is formed on the guide. The second main light guiding portion 35C connects a portion of a main light guiding portion 320 to the front of the camera 50 at an incidence portion 310, and is located below the main light guiding portion 320.

The light guide 30F is an approximately U-shaped transparent resin member. When the flashing light 10F is attached to the vehicle 1, the light guide 30F is installed in front of the four light-emitting diodes 22 to 25. The guide 30F is fixed on the fire body 11 in an orientation in which the lower part 30Fa of the letter U is at the front side. The light guide 30F includes a main light guiding portion 32F having a fork shape which is divided into upper and lower portions along the outer edge of the letter U, and a secondary light guiding portion 33F formed between the upper portions. and lower splitters of the main light guiding portion 32F. The thickness of the secondary light guiding portion 33F in the left-right direction is smaller than the thickness of the main light guiding portion 32F in the left-right direction. The upper front light emitting diode 23 and the lower front light emitting diode 25 are attached to the light body 11 in an orientation in which the upper and lower light emitting diodes 23, 25 emit light forwards.

On the other hand, instead of the bearing portions 12a, inner lenses can be installed in spaces between the upper rear light-emitting diode 22 and the lower rear light-emitting diode 24 and an inner surface of the outer cover 12. With the inner lenses, a model desired light distribution can be formed by controlling the light emitted by the upper rear light-emitting diode 22 and the lower rear light-emitting diode 24. In addition, fine irregularities such as, for example, streaks can be formed in an area of the cache 12 through which light directed towards the lateral side of the vehicle passes. With fine irregularities, the light emitted from the secondary light guide 33F is scattered and emitted towards the lateral side of the vehicle. Thus, the visibility of the flashing light 10F can be further improved. In this way, in the flashing light 10F according to the present reference example, a large light emitting area is provided by the light guide 30F of the light emitting element 60, and a light distribution pattern. desired is formed by the upper rear light-emitting diode 22 and the lower rear light-emitting diode 24 of the light-emitting element 60 so that visibility is improved.
