SUMMERY OF THE UTILITY MODEL

Problem to be solved by utility model

In the vehicle lamp using the organic EL panel as the Light source as described above, the organic EL panel is disposed by being attached to the mounting body, but since the organic EL panel is a planar Light source, the area occupied by the organic EL panel in the lamp chamber is likely to be larger than other Light sources such as a Light Emitting Diode (LED) used as the Light source, and accordingly, the size of the mounting body is likely to be larger.

Therefore, the mounting body is easily conspicuous in the lamp chamber, and there is a possibility that visibility of the vehicle lamp by a viewer may be reduced.

Therefore, the present invention aims to improve visibility.

Means for solving the problems

In a first aspect, a vehicle lamp according to the present invention includes: a lamp housing having an opening; a cover for sealing the opening; an organic electroluminescent panel having a light-emitting surface; and a mount body on which the organic electroluminescence panel is mounted, the mount body being formed to be transparent.

Thus, since the transparent attachment body is disposed in the internal space formed by the lamp housing and the cover, the attachment body is less likely to be conspicuous.

In a second aspect, in the vehicle lamp according to the present invention, it is preferable that an insertion hole is formed in the mounting body, and the organic el panel is mounted to the mounting body with a portion thereof inserted into the insertion hole.

Thereby, the organic electroluminescence panel is held by the mounting body so that a part of the organic electroluminescence panel is inserted into the insertion hole.

In a third aspect, in the vehicle lamp according to the present invention described above, it is preferable that the vehicle lamp is provided with a light source that emits light, and the light emitted from the light source is transmitted through the attachment body.

Thus, light emitted from the light source passes through the mounting body, and light emitted from the light source and light emitted from the organic electroluminescence panel are emitted to the outside.

In a fourth aspect, in the vehicle lamp according to the present invention, it is preferable that at least a part of each of the inner surface of the lamp housing and the surface of the attachment body be a reflecting surface.

In a fifth aspect, in the vehicle lamp according to the present invention, it is preferable that at least a part of the attachment body is a light guide body that conducts light emitted from the light source.

Thereby, the light emitted from the light source is transmitted through a part of the mounting body and emitted.

In a sixth aspect, in the vehicle lamp according to the present invention as set forth in the above, it is preferable that the mounting body is provided with a mounting portion to which the organic el panel is mounted, one surface of the mounting portion is formed as a mounting surface to which the organic el panel is mounted, and the other surface of the mounting portion opposite to the mounting surface is formed as a light emitting surface from which light emitted from the light source is emitted.

In this way, since the organic el panel is mounted on the mounting portion and light is emitted from the light exit surface of the mounting portion, light can be emitted toward both sides of the mounting portion.

In a seventh aspect, in the vehicle lamp according to the present invention, it is preferable that the organic el panel is one turn larger than the mounting surface.

In an eighth aspect, in the vehicle lamp according to the present invention, it is preferable that the organic el panel is attached to the attachment body in a bent state.

Thereby, light is emitted from the curved organic electroluminescence panel.

Effect of the utility model

According to the present invention, since the transparent attachment body is disposed, the attachment body is less likely to be conspicuous, and it is difficult to recognize the presence of the attachment body from the outside of the vehicle lamp, and thus the visibility can be improved.

Detailed Description

Hereinafter, a mode for implementing the vehicle lamp according to the present invention will be described with reference to the drawings.

In the embodiments described below, the vehicle lamp according to the present invention is applied to a vehicle lamp such as a tail lamp disposed at a rear end portion of a vehicle body. Furthermore, the present invention can be widely applied to various lamps for vehicles, such as a head lamp, a tail lamp, a width indicator lamp, a turn signal lamp, a brake lamp, a daytime running lamp (daytime running lamp), a turn signal lamp (turning lamp), a hazard lamp, a position lamp, a backup lamp, a fog lamp, or a combination lamp in which the lamps are combined.

In the following description, the vehicle lamp is set to show the front-rear, up-down, left-right directions in a state where the vehicle lamp is disposed at the rear end portion of the vehicle body. However, the front-back, up-down, left-right directions shown below are set for convenience of explanation, and the present invention is not limited to the above-described directions. Although the following description will describe an example of a vehicle lamp using an organic electroluminescence panel as a light source, the organic electroluminescence panel includes an organic electroluminescence display for displaying characters, graphics, and the like.

Integral structure of vehicle lamp

First, the overall configuration of the vehicle lamp 1 will be described (see fig. 1 to 5).

The

vehicle lamps

1 and 1 are disposed, for example, at both left and right end portions of a rear end portion of the vehicle body 100 (see fig. 1). The vehicle lamp 1 is configured by, for example, a first lamp portion 2 disposed in a non-movable portion such as a body portion 101 of a vehicle body 100 and a second lamp portion 3 disposed in a movable portion such as a trunk lid 102.

In the present invention, the vehicle lamp may be configured only by the first lamp unit 2, or may be configured only by the second lamp unit 3.

As described above, the vehicle lamp 1 has the first lamp unit 2 disposed on the body 101 and the second lamp unit 3 disposed on the trunk lid 102, and the first lamp unit 2 and the second lamp unit 3 are positioned so as to be adjacent to each other in a state where the trunk lid 102 is closed.

In the above description, the example in which the first lamp unit 2 is disposed on a non-movable part such as the main body 101 and the second lamp unit 3 is disposed on a movable part such as the trunk lid 102 is shown, but conversely, the first lamp unit 2 may be disposed on a movable part such as the trunk lid 102 and the second lamp unit 3 may be disposed on a non-movable part such as the main body 101. Further, both the first lamp unit 2 and the second lamp unit 3 may be disposed on the movable portion, or both the first lamp unit 2 and the second lamp unit 3 may be disposed on the non-movable portion.

The first lamp unit 2 includes a lamp housing 4 that is open rearward, and a cover 5 that closes the opening of the lamp housing 4 (see fig. 2 and 3). The lamp housing 6 is constituted by the lamp case 4 and the cover 5, and an inner space of the lamp housing 6 is formed as a lamp chamber 6 a.

An attachment body 7 is disposed in the lamp chamber 6a, and the attachment body 7 is attached to, for example, the lamp housing 4 in the lamp chamber 6 a. The attachment body 7 is formed to be transparent, and has a base portion 8 located on the front side, and

attachment portions

12, 12 projecting obliquely upward and rearward from the base portion 8, respectively.

The base portion 8 is formed in a step shape, and an upper step portion 9, a middle step portion 10, and a lower step portion 11 are continuous in order from above.

The

attachment portions

12, 12 are formed in a horizontally long flat plate shape, and protrude from rear end portions of the respective upper end portions of the upper stage portion 9, the middle stage portion 10, and the lower stage portion 11, respectively. The lower surface of the mounting portion 12 is formed as a mounting surface 12 a.

First organic EL panels (organic electroluminescence panels) 13, and 13 are attached to the attachment surfaces 12a, and 12a of the attachment body 7, for example, by bonding.

The first

organic EL panels

13, 13 are larger than the mounting surfaces 12a, respectively, and have outer peripheral portions partially protruding from the mounting surfaces 12a, respectively, in a state of being mounted on the mounting

portions

12, 12.

Since a part of the outer peripheral portion of the first organic EL panel 13 protrudes from the mounting surface 12a, the mounting body 7 is less likely to be visually recognized from the outside, and visibility is improved. Further, by forming the first organic EL panel 13 to have a size in which a part of the outer peripheral portion protrudes from the mounting surface 12a, the irradiation range of light emitted from the first organic EL panel 13 can be enlarged, and the luminance can be improved.

The first organic EL panel 13 is formed in a flat plate shape, and a surface opposite to the surface attached to the mounting surface 12a is formed as a light emitting surface 13 a.

In the first lamp unit 2 configured as described above, light emitted from the first

organic EL panels

13, and 13 passes through the cover 5 and is mainly emitted rearward.

In the first lamp unit 2, at least a part of the inner surface of the lamp housing 4 and the surfaces of the mounting body 7 may be formed as a reflecting surface, and in this case, a part of the light emitted from the first

organic EL panels

13, and 13 is reflected by the reflecting surface and mainly irradiated rearward.

The second lamp unit 3 includes a lamp housing 14 that is open rearward, and a cover 15 that closes the opening of the lamp housing 14 (see fig. 2 and 4). The lamp housing 16 is constituted by the lamp housing 14 and the cover 15, and an internal space of the lamp housing 16 is formed as a lamp chamber 16 a.

An attachment body 17 is disposed in the lamp chamber 16a, and the attachment body 17 is attached to, for example, the lamp housing 14 in the lamp chamber 16 a. The attachment body 17 is formed to be transparent and has a base portion 18 positioned on the front side, a first attachment portion 19 projecting rearward from a position near the lower end of the base portion 18, a connection portion 20 projecting obliquely upward and rearward from a position near the rear end of the first attachment portion 19, and a second attachment portion 21 continuous with the upper end of the connection portion 20.

The base portion 18 is formed in a flat plate shape that is horizontally long in the front-rear direction.

The first mounting portion 19 is formed in a plate shape extending in the left-right direction and facing in the up-down direction, and the rear surface is formed as a mounting surface 19 a. The mounting surface 19a is a surface facing obliquely downward and rearward.

The second attachment portion 21 protrudes obliquely downward and rearward from the upper end portion of the connection portion 20, and has an upper surface formed as an attachment surface 21 a. The mounting surface 21a is gently curved so that an intermediate portion in the front-rear direction is obliquely upwardly and rearwardly convex.

A second organic EL panel (organic EL panel) 22 is attached to the attachment surface 19a of the first attachment portion 19 by, for example, bonding.

The second organic EL panel 22 is larger than the mounting surface 19a, and at least a part of the outer peripheral portion thereof protrudes from the mounting surface 19a in a state of being mounted on the first mounting portion 19.

Since at least a part of the outer peripheral portion of the second organic EL panel 22 protrudes from the mounting surface 19a, the mounting body 17 is less likely to be visually recognized from the outside, and visibility is improved. Further, by forming the second organic EL panel 22 to have a size such that at least a part of the outer peripheral portion thereof protrudes from the mounting surface 19a, the irradiation range of light emitted from the second organic EL panel 22 can be enlarged, and the luminance can be improved.

The surface of the second organic EL panel 22 opposite to the surface attached to the attachment surface 19a is a light emitting surface 22 a.

A third organic EL panel (organic EL panel) 23 is attached to the attachment surface 21a of the second attachment portion 21 by, for example, bonding.

The third organic EL panel 23 is larger than the mounting surface 21a, and at least a part of the outer peripheral portion thereof protrudes from the mounting surface 21a in a state of being mounted on the second mounting portion 21.

Since at least a part of the outer peripheral portion of the third organic EL panel 23 protrudes from the mounting surface 21a, the mounting body 17 is less likely to be visually recognized from the outside, and visibility is improved. Further, by forming at least a part of the outer peripheral portion of the third organic EL panel 23 to have a size protruding from the mounting surface 21a, the irradiation range of light emitted from the third organic EL panel 23 can be enlarged, and the luminance can be improved.

The surface of the third organic EL panel 23 opposite to the surface attached to the attachment surface 21a is a light emitting surface 23 a. The third organic EL panel 23 is attached to the second attachment portion 21 in a state where an intermediate portion in the front-rear direction of the light emitting surface 23a is gently curved so as to be convex obliquely upward and rearward.

In a state where the second organic EL panel 22 and the third organic EL panel 23 are attached to the first attachment portion 19 and the second attachment portion 21, respectively, an upper end portion of the second organic EL panel 22 and a lower end portion of the third organic EL panel 23 overlap in the front-rear direction.

By thus placing the upper end portion of the second organic EL panel 22 and the lower end portion of the third organic EL panel 23 in a state of overlapping in the front-rear direction, the mounted body 17 is not easily viewed from the outside, and visibility is improved.

In the second lamp unit 3 configured as described above, light emitted from the second organic EL panel 22 and the third organic EL panel 23 passes through the cover 15 and is mainly emitted rearward.

In the second lamp unit 3, at least a part of the inner surface of the lamp housing 14 and the surface of the mounting body 17 may be formed as a reflection surface, and in this case, a part of the light emitted from the second organic EL panel 22 and the third organic EL panel 23 is reflected by the reflection surface and mainly irradiated rearward.

As described above, in the vehicle lamp 1, since the attachment body 7 and the attachment body 17 are formed to be transparent, the attachment body 7 and the attachment body 17 are less likely to be conspicuous, and the presence of the attachment body 7 and the attachment body 17 is less likely to be recognized from the outside of the vehicle lamp 1, so that the visibility can be improved.

In particular, since the mount 7 and the mount 17 are less likely to be conspicuous, the second organic EL panel 22 and the third organic EL panel 23 are easily recognized as being in a floating state, and the design and visibility can be improved.

Further, since mounting body 7 and mounting body 17 are formed to be transparent, reflection of light is less likely to occur on the surfaces of mounting body 7 and mounting body 17, light affecting the light distribution is less likely to occur, and a desired light distribution can be secured.

Further, in the second lamp unit 3, since the third organic EL panel 23 is attached to the attachment body 17 in a bent state, light is emitted from the bent third organic EL panel 23, and a necessary light distribution can be secured while a sufficient light irradiation range is secured.

In addition, although the example in which the third organic EL panel 23 is bent is shown in the above description, the first organic EL panel 13 and the second organic EL panel 22 may be mounted on the mounting body 7 and the mounting body 17, respectively, in a bent state.

In addition, although the example in which three organic EL panels are arranged in the first lamp unit 2 and two organic EL panels are arranged in the second lamp unit 3 has been described above, the number of the organic EL panels arranged in the first lamp unit 2 and the second lamp unit 3 may be one or more, respectively, and the number thereof may be any number.

In addition, an antireflection treatment such as an antireflection film for preventing reflection of light may be applied to the mounting body 7 and the mounting body 17 (see fig. 5). Taking the mounting body 7 as an example, the antireflection films 24, … may be applied to the rear surface 9a of the upper stage portion 9, the rear surface 10a of the middle stage portion 10, the upper surface 10b of the middle stage portion 10, the rear surface 11a of the lower stage portion 11, and the upper surface 11b of the lower stage portion 11, respectively. The antireflection films 24, … may be applied to the upper surfaces 12b, 12b of the mounting

portions

12, 12 located at the center in the vertical direction and at the lowermost positions, respectively.

By thus applying the antireflection treatment to the mounting body 7 and the mounting body 17, the light emitted from the first organic EL panel 13, the second organic EL panel 22, and the third organic EL panel 23 is not reflected on the surface subjected to the antireflection treatment, and therefore the mounting body 7 and the mounting body 17 become less conspicuous, and further improvement in visibility can be achieved.

< modification of mounting body or the like >

Next, various modifications of the mounting body and the like will be described (see fig. 6 or 12).

In the following modifications, when the same structure as the mounting body 7, the mounting body 17, the first organic EL panel 13, the second organic EL panel 22, or the third organic EL panel 23 is adopted, the same reference numerals as those described above are given, and detailed description thereof is omitted.

The first modification is an example in which an organic EL panel is inserted into a mounting body 7 and held by the mounting body (see fig. 6).

Projections 25, 25 projecting obliquely upward and rearward from the base portion 8 are provided on the lower side of the

attachment portions

12, 12 of the attachment body 7, respectively, and the projecting amounts of the projections 25, 25 from the base portion 8 are set smaller than the projecting amounts of the

attachment portions

12, 12 from the base portion 8. The space between the mounting portion 12 and the projecting portion 25 is formed as an insertion hole 7 a.

A part of the outer peripheral portion of the first organic EL panel 13 is inserted into the insertion hole 7a and attached to the attachment surface 12a by, for example, bonding.

By thus attaching a part of the first organic EL panel 13 to the mounting body 7 in a state of being inserted into the insertion hole 7a, the part of the first organic EL panel 13 is inserted into the insertion hole 7a and held by the mounting body 7, and therefore, it is possible to improve workability in mounting the first organic EL panel 13 to the mounting body 7.

Further, a structure having an insertion hole may be applied to the mounting body 17.

The second modification is an example in which the coupling portion 20 is coupled to the first mounting portion 19 to form the mounting body 17 (see fig. 7).

The first mounting portion 19 is formed with a coupling hole 19b opened upward. The coupling portion 20 and the second attachment portion 21 are provided as parts of a member 26 separate from the base portion 18 and the first attachment portion 19, and the attachment body 17 is configured by inserting the coupling portion 20 into the coupling hole 19b and coupling the member 26 to the first attachment portion 19.

In the above configuration, the first mounting portion 19 on which the second organic EL panel 22 is mounted in advance is coupled to the member 26 on which the third organic EL panel 23 is mounted in advance, thereby configuring the mounting body 17 on which the second organic EL panel 22 and the third organic EL panel 23 are mounted. Therefore, it is possible to improve the workability in the mounting operation of the second organic EL panel 22 and the third organic EL panel 23 to the mounting body 17 without mounting the second organic EL panel 22 and the third organic EL panel 23 on the same member.

In particular, in a configuration in which a part of the second organic EL panel 22 and a part of the third organic EL panel 23 overlap in the front-rear direction, there is a possibility that both of them interfere with the mounting operation of the second organic EL panel 22 and the third organic EL panel 23. Therefore, by configuring such that the second organic EL panel 22 and the third organic EL panel 23 are mounted on separate members as described above, the mounting operation of the second organic EL panel 22 and the third organic EL panel 23 to the mounting body 17 can be easily and smoothly performed.

Further, a structure in which a separate member is coupled to another member may be applied to the mounting body 7.

The third modification is an example in which another light source is applied to the organic EL panel (see fig. 8 and 9).

In the above example, for example, the mounting body 27 is used. The attachment body 27 is formed to be transparent, and has a base portion 28 formed in a substantially flat plate shape that is horizontally long in the vertical direction, a first attachment portion 29 that protrudes diagonally upward and rearward from a front end portion of the base portion 28, and a second attachment portion 30 that protrudes diagonally downward and rearward from the front end portion of the base portion 28.

The front surface of the base portion 28 is formed as a light incident surface 28a, and the rear surface of the base portion 28 is formed as a light emitting surface 28 b. The outer peripheral surface of the base portion 28 between the light incident surface 28a and the light emitting surface 28b is formed as a reflection surface 28 c. The reflecting surface 28c has a function of internally reflecting (totally reflecting) the light transmitted through the base portion 28, and for example, the reflecting surface 28c may have a stepped shape for internally reflecting the light.

The first attachment portion 29 and the second attachment portion 30 are gently curved so that, for example, the center portions in the front-rear direction thereof are convex rearward, and the surfaces thereof facing the base portion 28 are formed as attachment surfaces 29a and 30a, respectively.

Organic EL panels

31 and 31 are attached to the attachment surface 29a of the first attachment portion 29 and the attachment surface 30a of the second attachment portion 30, for example, by bonding.

The

organic EL panels

31 and 31 are larger than the mounting

surfaces

29a and 30a, and in a state of being mounted on the first mounting portion 29 and the second mounting portion 30, a part of the outer peripheral portions thereof protrude from the mounting

surfaces

29a and 30a, respectively.

The surfaces of the

organic EL panels

31 and 31 opposite to the surfaces attached to the attachment surfaces 29a and 30a are formed as light emitting

surfaces

31a and 31a, respectively. The

organic EL panels

31 and 31 are attached to the first attachment portion 29 and the second attachment portion 30 in a state of being gently curved so that the center portions thereof in the front-rear direction are convex toward substantially the rear, for example. The lower end of the organic EL panel 31 attached to the first attachment portion 29 is flush with the rear end of the upper surface of the base portion 28, and the upper end of the organic EL panel 31 attached to the second attachment portion 30 is flush with the rear end of the lower surface of the base portion 28.

A light source 32 is disposed in front of the mounting body 27 at a position facing the light incident surface 28 a. The light source 32 is disposed on, for example, an unillustrated disposing member. The Light source 32 is, for example, a Light Emitting Diode (LED).

In the above configuration, light emitted from the

organic EL panels

31 and 31 passes through the cover and is mainly emitted rearward. The light emitted from the light source 32 enters the base portion 28 from the light entrance surface 28a, is internally reflected by the reflection surface 28c, is transmitted toward the light exit surface 28b, is emitted from the light exit surface 28b, and is emitted rearward through the cover.

Since the light emitted from the light source 32 passes through the base portion 28 of the attachment 27 and the light emitted from the light source 32 and the light emitted from the

organic EL panels

31 and 31 are radiated to the outside, the light emitted from the organic EL panels 31 and the light emitted from the light source 32 are radiated as illumination light, and it is possible to improve the luminance, and it is possible to improve the degree of freedom in design and secure a desired light distribution.

Further, since the base portion 28, which is a part of the attachment body 27, functions as a light guide for guiding the light emitted from the light source 32, the light emitted from the light source 32 is guided and emitted by a part of the attachment body 27, and thus the number of components can be reduced and the degree of freedom in design can be improved by improving the functionality of the attachment body 27.

Further, since the

organic EL panels

31 and 31 are attached to the attachment body 27 in a bent state, light is emitted from the bent

organic EL panels

31 and 31, and a necessary light distribution can be secured while a sufficient light irradiation range is secured.

The fourth modification is an example in which another light source is used in addition to the organic EL panel in the configuration using the mounting body 7 (see fig. 10).

Lens steps 8a, and 8a are formed on the rear surface of the base portion 8 of the attachment body 7 so as to be vertically separated. The lens steps 8a, 8a are, for example, diffusion steps.

A support plate 33 is disposed on the front side of the attachment body 7 at a position facing the base portion 8. The support plate 33 is vertically distributed and has flat plate-like

vertical portions

33a, 33a facing in the front-rear direction. On the rear surfaces of the vertical portions 33a,

substrates

34, 34 having circuit patterns, and light sources 35, … mounted on the rear surfaces of the

substrates

34, 34 are arranged, respectively. As the light source 35, for example, a light emitting diode is used.

In the above configuration, the light emitted from the first

organic EL panels

13, and 13 passes through the cover 5 and is mainly emitted rearward. The light emitted from the light sources 35, … enters the base portion 8 of the attachment body 7, is diffused by the lens steps 8a, and is irradiated rearward through the cover 5.

Since the light emitted from the light sources 35, and … passes through the base portion 8 of the attachment 7 and the light emitted from the light sources 35, and … and the light emitted from the first organic EL panel 13 are radiated to the outside, the light emitted from the first organic EL panel 13 and the light emitted from the light sources 35, and … are radiated as illumination light, and thus it is possible to improve the luminance, improve the degree of freedom in design, and secure a necessary light distribution.

The fifth modification is an example in which another light source is used in addition to the organic EL panel in the configuration using the mounting body 17 (see fig. 11).

Lens steps 18a, 18a are formed on the rear surface of the base portion 18 of the attachment body 17 above and below the first attachment portion 19. The lens steps 18a, 18a are, for example, diffusion steps.

A support plate 36 is disposed on the front side of the attachment body 17 at a position facing the base portion 18. On the rear surface of the support plate 36 are disposed:

substrates

37, 37 having circuit patterns in front of the lens steps 18a, respectively; and light sources 38, … mounted on the rear surfaces of the

substrates

37, 37. As the light source 38, for example, a light emitting diode is used.

In the above configuration, the light emitted from each of the second organic EL panel 22 and the third organic EL panel 23 passes through the cover 15 and is mainly emitted rearward. The light emitted from the light sources 38, … enters the base portion 8 of the attachment body 7, is diffused by the lens steps 18a, and is emitted rearward through the cover 15.

Since the light emitted from the light sources 38, and … passes through the base portion 18 of the mounting body 17 and the light emitted from the light sources 38, and … and the light emitted from the second organic EL panel 22 and the third organic EL panel 23 are radiated to the outside, the light emitted from the second organic EL panel 22 and the third organic EL panel 23 and the light emitted from the light sources 38, and … are radiated as illumination light, and thus it is possible to improve the luminance, increase the degree of freedom in design, and secure a desired light distribution.

The sixth modification is an example in which another light source is used in addition to the organic EL panel (see fig. 12 and 13).

In the above example, for example, the mounting body 39 is used. The mounting body 39 is formed to be transparent, and has: a base portion 40 formed in a substantially flat plate shape and laterally long in the front-rear direction; and a mounting portion 41 projecting substantially rearward from the base portion 40. Further, a plurality of mounting portions 41 are provided at intervals in the left-right direction.

A part of the front surface of the base portion 40 is formed as a light incident surface 40 a. The base portion 40 may be formed in a flat plate shape, and the intermediate portion in the left-right direction may be gently curved so as to be convex forward or rearward.

The mounting portion 41 is formed in a shape in which the vertical width decreases as the direction goes to the rear, for example, and is gently curved so that the curved direction is one of the left and right directions. The mounting portion 41 is slightly inclined so that the rear end thereof is positioned more laterally than the front end thereof. One surface of the mounting portion 41 in the lateral direction (thickness direction) is formed as a mounting surface 41a, and the other surface of the mounting portion 41 in the lateral direction is formed as a light exit surface 41 b.

The surface of the outer surface of the mounting portion 41 other than the light exit surface 41b is formed as a reflection surface 41c that internally reflects (totally reflects) light transmitted through the inside of the mounting portion 41. The reflecting surface 41c may have a stepped shape for internally reflecting light, for example.

The organic EL panel 42 is attached to the attachment surface 41a of the attachment portion 41 by, for example, bonding.

The organic EL panel 42 is larger than the mounting surface 41a, and a part of the outer peripheral portion thereof protrudes from the mounting surface 41a in a state of being mounted on the mounting portion 41.

The surface of the organic EL panel 42 opposite to the surface attached to the attachment surface 41a is a light emitting surface 42 a. The organic EL panel 42 is attached to the attachment portion 41 in a gently curved state such that the curved direction is one of the left and right directions.

A light source 43 is disposed in front of the mounting body 39 at a position facing the light incident surface 40 a. The light source 43 is disposed on, for example, an unillustrated disposing member. The Light source 43 is, for example, a Light Emitting Diode (LED).

In the above configuration, the light emitted from the organic EL panel 42 is transmitted through the cover and mainly irradiated rearward. The light emitted from the light source 43 enters the base portion 40 through the light incident surface 40a, is internally reflected by the reflection surface 41c, is transmitted through the mounting portion 41, is emitted from the light emitting surface 40b, and is emitted rearward through the cover.

In order to irradiate the light emitted from the light emitting surface 42a of the organic EL panel 42 and the light emitting surface 41b of the mounting portion 41 rearward, for example, a reflection process or the like may be applied to the rear surface of the base portion 40 so that part of the light emitted from the light emitting surface 42a and the light emitting surface 41b is reflected by the rear surface of the base portion 40.

Since the light emitted from the light source 43 passes through the mounting body 39 and the light emitted from the light source 43 and the light emitted from the organic EL panel 42 are radiated to the outside, the light emitted from the organic EL panel 42 and the light emitted from the light source 43 are radiated as illumination light, and thus it is possible to improve the luminance, improve the degree of freedom in design, and secure a necessary light distribution.

Further, since the mounting portion 41, which is a part of the mounting body 39, functions as a light guide body that guides light emitted from the light source 43, the light emitted from the light source 43 is guided and emitted by the part of the mounting body 39, and thus the number of components can be reduced and the degree of freedom in design can be improved by improving the functionality of the mounting body 39.

Further, one surface of the mounting portion 41 is formed as a mounting surface 41a on which the organic EL panel 42 is mounted, and the other surface of the mounting portion 41 on the opposite side of the mounting surface 41a is formed as a light emitting surface 41b that emits light emitted from the light source 43.

Therefore, since the organic EL panel 42 is mounted on the mounting portion 41 and light is emitted from the light emitting surface 41b of the mounting portion 41, light can be emitted toward both sides of the mounting portion 41, so that it is possible to improve the degree of freedom in design and to sufficiently secure the irradiation range of light.

Further, since it is recognized that light is emitted from both surfaces of the mounting portion 41, a viewer can recognize a three-dimensional light emission state, and design can be improved.

Further, since the organic EL panel 42 is attached to the attachment body 39 in a bent state, light is emitted from the bent organic EL panel 42, and a necessary light distribution can be secured while a sufficient light irradiation range is secured.

Although the mounting portion 41 may be formed as a part of the mounting surface 41a and the reflection surface 41c, and the mounting surface 41a may have a stepped shape for internally reflecting light, a surface of the organic EL panel 42 mounted on the mounting portion 41 opposite to the light emission surface 42a may be formed as a reflection surface, and light incident on the mounting portion 41 may be internally reflected.
