Description

  The present invention relates to a vehicular lamp in which a plate-like light emitter is housed in a lamp chamber as a light source.

  In the automotive lamp industry in recent years, a lamp can be made thin by using a plate-like organic EL illuminant as a light source.

  For example, in Patent Document 1 below, in a lamp room defined by a lamp body and a front cover, a first light emitting surface facing the front-rear direction (axle direction) of an automobile and a side of the automobile adjacent to the first light emitting surface are disclosed. A vehicular lamp is described in which a bent plate-shaped organic EL illuminator having a second light emitting surface facing the surface is disposed as a light source. The light emitted from the lamp is guided over a wide range from the direction along the axle to the side of the vehicle, and the visibility of the lamp is excellent.

  The plate-shaped organic EL light emitter, which is a light source, has a structure in which the organic EL display element, which is a light source body, is in close contact with the translucent substrate. The organic EL display element is organic between a pair of electrode layers. It has a laminated structure in which a light emitting layer is sandwiched.

JP 2013-45523 A (see paragraphs 0015 and 0016, FIGS. 1 and 2)

  However, when Patent Document 1 is applied to a marker lamp such as a tail lamp, a stop lamp, or a clearance lamp, the first light-emitting surface of the bent plate-shaped organic EL light emitter is directed in the axle direction. A first problem is that the light is reflected from the first light emitting surface of the light emitter in the marker lamp and may act as glare light on the driver of the following vehicle.

  In particular, when the back electrode layer of the organic EL light emitting element is made of metal, the metal gloss surface of the back electrode layer becomes a mirror surface to increase the reflectivity at the first light emitting surface, and the generation of glare light. It becomes even more obvious.

  Moreover, in the said patent document 1, since light emission in the light emission surface of a plate-shaped light-emitting body is planar, there also exists the 2nd problem that only light emission without a feeling of depth is obtained.

The present invention has been made in view of the above-described problems of the prior art.
To provide a vehicular lamp that does not cause glare light to the succeeding vehicle even if the light of the headlamp of the succeeding vehicle is reflected by the light emitting surface of the plate-like light emitter in the lamp chamber, and that can produce novel light emission with a sense of depth. It is in.

In order to achieve the above object, in the present invention (Claim 1), at least two plate-like light emitters as light sources are arranged in the lamp chamber defined by the lamp body and the front cover. In vehicle lamps arranged adjacent to each other,
The light emitting surfaces of the plate light emitters are arranged to face different predetermined directions that are inclined with respect to the axle, respectively, and the light emission surfaces of at least one other plate light emitter are adjacent to each other. It was constructed so that the light emission of the surface was reflected as a virtual image.
(Operation) For example, when the present invention is used as a marker lamp attached to the rear part of a vehicle body, each of the light emitting surfaces of the plurality of plate-like light emitters arranged in the lamp chamber does not face the axle. Even if the light of the headlamp of the following vehicle is reflected by the respective light emitting surfaces of the plate-like light emitters, the reflected light from any of the light emitting surfaces is directed away from the driver of the following vehicle and No glare light.

  Further, since the light emission of the light emitting surface of another adjacent light emitter appears as a virtual image on the light emitting surface of at least one light emitter, the light emission of the light emitting surface of the plate-like light emitter can be seen three-dimensionally through the front cover.

  Further, in order for the light emission surface of one of the other light emitters to be reflected as a virtual image on the light emitting surface of one light emitter, the adjacent light emitting surfaces are arranged at a predetermined angle. After the light of the headlamp of the following vehicle is reflected by the light emitting surface of one plate-like light emitter, it may be reflected by the reflective surface of another adjacent light emitting device and directed to the driver of the following vehicle. Since the energy of light is weakened by reflection, it does not become glare light.

  According to claim 2, in the vehicular lamp according to claim 1, the plate-like light emitter includes a translucent substrate constituting the light emitting surface, and a front electrode layer integrated with the substrate. An organic EL display element which is a light source body in which an organic light emitting layer and a back electrode layer are laminated, and the back electrode layer of at least one plate-like light emitter is formed of a reflective layer having a metallic gloss surface.

  (Operation) The back-side electrode layer of at least one plate-like light emitter is composed of a reflective layer having a metallic gloss surface, and the organic light-emitting layer emits light efficiently from a light-transmitting substrate that is the light-emitting surface of the plate-like light emitter. It is comprised so that it may radiate | emit.

  Further, in the plate-like light emitter in which the back-side electrode layer is composed of a reflective layer having a metallic glossy surface, the back-side electrode layer acts as a mirror surface, and the light-emitting surface of the plate-like light emitter is adjacent to the plate-like light emitter. Since the light emission from the light emitting surface appears as a clear virtual image, the light emission from the light emitting surface of the plate-like light emitter can be seen more three-dimensionally through the front cover.

  According to a third aspect of the present invention, in the vehicular lamp according to the first aspect, the plate-like light emitter includes a translucent substrate that constitutes the light emitting surface, and a front electrode layer that is integrated with the substrate. An organic EL display element which is a light source body in which an organic light emitting layer and a back side electrode layer are laminated, and the back side electrode layer of at least one plate-like light emitter is configured to be transparent.

  (Operation) When the back side electrode layer of one plate-like light emitter is composed of a reflective layer having a metallic glossy surface, as explained in the operation of claim 2, the back side electrode layer acts as a mirror surface, The light emission surface of one plate-like illuminant is effective in that the light emission from the light emission surface of another adjacent plate-like illuminant appears as a clear virtual image, giving a sense of depth to the light emission of the lamp. However, it is not preferable in that the back-side electrode layer acts as a mirror surface to increase the reflectance on the light emitting surface of the plate-like light emitter and suppress the generation of glare light.

  That is, when the light of the headlamp of the following vehicle is sequentially reflected by the light emitting surface of the adjacent plate-like light emitter in the lamp chamber and heads for the driver of the following vehicle, the intensity of the light is reduced to some extent by the two reflections, Reflected light on the light emitting surface of the plate-like light emitter is reflected light on the translucent substrate surface constituting the light emitting surface and reflected light on the metallic glossy surface (mirror surface) of the back-side electrode layer of the plate-like light emitter. Since the added light has an intensity close to glare light, it is not preferable for the driver of the following vehicle.

  However, in claim 3, since the back side electrode layer of one plate-like light emitter is transparent, the headlamp incident on the organic EL display element from the translucent substrate that is the light-emitting surface of the one plate-like light emitter. Since most of the light transmitted through the transparent back-side electrode layer and reflected by the back-side electrode layer is negligible, the light that is sequentially reflected by the light-emitting surface of the adjacent plate-like light emitter and directed toward the driver of the following vehicle The intensity is surely reduced and no glare light is generated.

  According to a fourth aspect of the present invention, in the vehicular lamp according to the third aspect of the present invention, the second light source is arranged behind a plate-like light emitter in which the back side electrode layer is configured to be transparent.

  (Operation) Since the plate-like illuminant having the back side electrode layer made transparent can transmit light, light emission of the second light source can be seen through the plate-like illuminant emitting light of a predetermined color. That is, the light emission of the light emitting surface of the plate-like light emitter can be seen three-dimensionally through the front cover, and the light emission of the second light source can be seen behind the plate-like light emitter.

  For example, the tail-and-stop lamp is configured so that the light emission of the plurality of plate-like light emitters corresponds to the lighting of the tail lamp, and the light emission of the plurality of plate-like light emitters and the light emission of the second light source correspond to the lighting of the stop lamp. can do.

  As apparent from the above description, according to the present invention (Claim 1), the light of the headlamp of the succeeding vehicle reflected on the light emitting surfaces of the plurality of light emitters in the lamp chamber is all from the driver of the succeeding vehicle. It goes in the direction of deviation, or light that has been reduced in intensity by two reflections and goes to the driver of the following vehicle, so it does not become glare light for the driver of the following vehicle. That is, the first problem of the prior art that the light of the headlamp of the following vehicle is reflected on the light emitting surface of the plate-like light emitter in the lamp chamber and becomes glare light for the following vehicle is solved.

  In addition, the light emitted from the other light emitting surface adjacent to the light emitting surface is reflected as a virtual image on at least one light emitting surface, and the light emitted from the light emitting surface of the plate-like light emitter can be seen three-dimensionally through the front cover. It will be a novel thing. That is, the second problem of the prior art that only light emission without a sense of depth can be obtained is solved.

  According to claim 2, the light emission of at least one plate-like light emitter is reflected as a clear virtual image on the light-emitting surface of the other plate-like light emitter, and the light emission of the light-emitting surface of the plate-like light emitter is transmitted through the front cover. Since it looks more three-dimensional, the light emitted from the lamp becomes more innovative and deep.

  According to claim 3, even if the light of the headlamp is sequentially reflected on the light emitting surface of the adjacent plate-like light emitter in the lamp chamber and becomes light directed to the driver of the following vehicle, the light emitting surface of the plate-like light emitter Due to the low reflectivity, the glare will not be generated for the driver of the following car.

  According to the fourth aspect, the light emission of the light emitting surface of another adjacent plate light emitter appears as a virtual image on the light emitting surface of at least one plate light emitter through the front cover, and Since the light emission of the second light source can be seen in the back, the light emission of the lamp becomes even more innovative with a sense of depth.

(A)-(d) is a longitudinal cross-sectional view of the tail and stop lamp which is the 5th, 6th, 7th, 8th Example of this invention.

  Hereinafter, embodiments of the present invention will be described based on examples.

  1 to 4 show a first embodiment in which the present invention is applied to a tail lamp.

  In FIG. 1, reference numeral 10 denotes a tail lamp attached to the left and right corners of the rear part of the automobile. The tail lamp 10 is disposed in a lamp chamber S defined by a lamp body 12 and a front cover 14 as shown in FIG. 2. A pair of plate-like light emitters 20A and 20B, which are light sources, are arranged so as to face each other vertically.

  The plate-like light emitting body 20A (20B) is formed in a rectangular plate shape that is horizontally long when viewed from the front, and as shown in FIG. 3, the transparent surface constituting the light emitting surface 20a (20b) of the light emitting body 20A (20B). The substrate 22 includes an organic EL display element 24 that is a light source body laminated and integrated so as to be in close contact with the back surface of the substrate 22, and an opaque resin cover 23 that covers the display element 24.

  The organic EL display element 24 has a structure in which a front-side electrode layer 25 serving as an anode, an organic light-emitting layer 26 and a back-side electrode layer 27 serving as a cathode are laminated, and is integrated so that the front-side electrode layer 25 is in close contact with the substrate 22. It has become. The front side electrode layer 25 and the organic light emitting layer 26 are both made of a transparent material, and the back side electrode layer 27 is made of a reflective layer having a metallic gloss surface, so that the organic light emitting layer 26 emits red light. The light is efficiently emitted from the light emitting surface 20a (20b), that is, the surface of the substrate 22 (see the arrow in FIG. 3).

  Specifically, when a lighting switch (not shown) of the tail lamp 10 is turned on, a DC voltage is applied to the organic EL display element 24, and holes are transferred from the front electrode layer 25 and electrons are transferred from the back electrode layer 27. The organic light emitting layer 26 emits red light when injected into the organic light emitting layer 26 and holes and electrons are combined. That is, in the tail lamp 10, the light emitting surfaces 20a and 20b of the plate-like light emitters 20A and 20B emit red light, and the light is distributed to the rear of the vehicle through the transparent front cover 14.

  In addition, as shown in FIGS. 2 and 4, the organic EL light emitters 20A and 20B have light emitting surfaces 20a and 20b facing rearward in parallel with the axles X and inclined 45 degrees with respect to the horizontal, that is, 90 degrees relative to each other. When the tail lamp 10 is viewed from the rear of the vehicle, the light emitted from the other light emitting surfaces 20b and 20a is reflected on the other light emitting surfaces 20b and 20b.

  For example, as shown in FIG. 4, the light emission La at a predetermined position Pa of the light emitting surface 20a of the plate-like light emitter 20A is reflected on the light emitting surface 20b of the adjacent plate-like light emitter 20B (a position Pa corresponding to the light emitting surface 20a ′). On the other hand, the light emission Lb at a predetermined position Pb of the light emitting surface 20b of the plate-like light emitter 20B is reflected on the light emission surface 20a of the adjacent plate-like light emitter 20A, corresponding to the virtual image (light emission surface 20b '). The light emission Lb ′) at the position Pb ′ is reflected, and all these light emission La, La ′, Lb, and Lb ′ are seen stereoscopically through the front cover 12.

  In particular, since the back-side electrode layer 27 of the plate-like light emitters 20A and 20B (the organic EL display element 24) is formed of a reflective layer having a metallic gloss surface, the back-side electrode layer 27 acts as a mirror surface, and the plate Since the light emission surfaces 20a and 20b of the plate-like light emitters 20A and 20B appear to have the light emission Lb and La of the light emission surfaces 20b and 20a of the adjacent plate-like light emitters 20B and 20A reflected as clear virtual images Lb 'and La'. The tail lamp 10 emits a sense of depth.

  Further, the light emitting surfaces 20a and 20b of the plate-like light emitters 20A and 20B are all directed toward the rear of the vehicle, but both are inclined with respect to the axle X, so that the light of the headlamp of the following vehicle is plate-like. Even if the light is reflected by the light emitting surface 20a of the light emitting body 20A or the light emitting surface 20b of the plate-like light emitting body 20B, each reflected light is directed in a direction other than the driver of the following vehicle. The light is reflected by the light emitting surface 20a of the light emitting body 20A or the light emitting surface 20b of the plate-like light emitting body 20B and does not directly act on the driver of the following vehicle as glare light.

  However, since the light emitting surfaces 20a and 20b of the plate-like light emitters 20A and 20B are both directed toward the rear of the vehicle and inclined 45 degrees with respect to the axle X, respectively, for example, as shown in FIG. After the light L of the headlamp is reflected by the light emitting surface 20a of the plate-like light emitter 20A and further reflected by the light emitting surface 20b of the plate-like light emitter 20B, the light L2 is directed toward the driver of the following vehicle.

In particular, in the plate-like light emitter 20A (20B), the back side electrode layer 27 of the plate-like light emitter 20A (20B) acts as a mirror surface, so that the reflection on the light emitting surface 20a (20b) of the plate-like light emitter 20A (20B). The light is a light obtained by adding the reflected light on the metallic gloss surface (mirror surface) of the back-side electrode layer 27 of the organic EL display element 24 to the reflected light on the surface of the transparent substrate 22 constituting the light emitting surface 20a (20b). And it has an intensity close to glare light. That is, when the reflected light from the light emitting surface 20a of the plate-like light emitter 20A or the light emitting surface 20b of the plate-like light emitter 20B directly hits the driver of the succeeding vehicle, the glare light is surely obtained.
However, the light reflected by the light emitting surfaces 20a and 20b of the plate-like light emitters 20A and 20B and directed toward the driver of the following vehicle is emitted from the light emitter 20A as indicated by reference numerals L1 and L1 ′ in FIG. After being reflected by the surface 20a and the back-side electrode layer 27, as indicated by reference numerals L2 and L2 ′, the light further reflected by the light-emitting surface 20b and the back-side electrode layer 27 of the plate-like light emitter 20B, that is, twice The light whose energy is weakened by the reflection of the light does not become glare light for the driver of the following car, and does not cause trouble for the driver of the following car.

  5 and 6 show an embodiment in which the present invention is applied to a tail and stop lamp.

  In FIG. 5, a tail and stop lamp 10A according to a second embodiment of the present invention is provided in the lamp chamber S defined by the lamp body 12 and the front cover 14, and the tail lamp 10 of the first embodiment described above. Similarly, a pair of plate-like light emitters 20C and 20D, which are light sources, are arranged so as to face each other vertically, and the light emitting surfaces 20c and 20d are arranged so as to be inclined 45 degrees with respect to the axle X, respectively.

  The plate-like light emitters 20C and 20D are formed in a rectangular plate shape that is horizontally long when viewed from the front, similarly to the light emitters 20A and 20B (see FIG. 3) constituting the tail lamp 10 of the first embodiment, and are shown in FIG. As described above, the transparent substrate 22 constituting the light emitting surface 20c (20d) of the light emitter 20C (20D), the organic EL display element 24A laminated and integrated on the back surface of the substrate 22, and the opaqueness covering the display element 24A A resin cover 23 is provided.

  Further, in the organic EL display element 24A, as in the organic EL display element 24 of the first embodiment described above, a front side electrode layer 25 serving as an anode, an organic light emitting layer 26, and a back side electrode layer 27A serving as a cathode are laminated. The structure is different from the plate-like light emitters 20A and 20B (the organic EL display element 24) of the first embodiment described above in that the back electrode layer 27A is transparent.

  And LED28 which is a 2nd light source is each arrange | positioned with the irradiation axis facing the front behind the plate-shaped light-emitting bodies 20C and 20D which are comprised transparently as a whole.

  Therefore, when a tail lamp lighting switch (not shown) is turned on, the light emitting surfaces 20c and 20d of the plate-like light emitters 20C and 20D emit red light, respectively, and are adjacent to the light emitting surfaces 20c and 20d. The red light emission of the light emitting surfaces 20d and 20c of the plate-like light emitters 20D and 20C is reflected as a virtual image, the red light emission of these light emitting surfaces 20c and 20d and the light emitting surfaces 20d and 20c reflected as a virtual image on the light emitting surfaces 20c and 20d. The red light emission appears as three-dimensional through the front cover 12 as the light emission of the tail lamp.

  In addition, since the back side electrode layer 27A of the plate-like light emitters 20C and 20D is configured to be transparent, the reflection due to the mirror surface action of the back side electrode layer 27 of the plate-like light emitters 20A and 20B of the first embodiment. Although not noticeable, since the interior of the lamp chamber S behind the plate-like light emitters 20C and 20D is dark, the light emission surfaces 20c and 20d of the plate-like light emitters 20C and 20D are reflected in the light emission of the adjacent light-emitting surfaces 20d and 20c. To some extent.

  Further, when a stop lamp lighting switch (not shown) is turned on by depressing the foot brake, the LED 28 as the second light source is turned on, and the light emitting surfaces 20c and 20d emit red light and the light emitting surface 20c. In addition to the red light emission of the light emitting surfaces 20d and 20c reflected as a virtual image in 20d, the red strong light emission L28 of the LED 28 behind the transparent plate-like light emitters 20C and 20D is three-dimensionally through the front cover 12 as the light emission of the stop lamp. appear.

  Further, since the back-side electrode layer 27A of the organic EL display element 24A is configured to be transparent, most of the headlamp light incident on the organic EL display element 24A from the light emitting surfaces 20c and 20d of the plate-like light emitters 20C and 20D. Since the light transmitted through the transparent back electrode layer 27A and reflected by the back electrode layer 27A is negligible, the light is sequentially reflected by the light emitting surfaces 20c and 20d of the adjacent plate-like light emitters 20C and 20D, and The intensity of the light toward the driver will definitely decrease, and it will not become glare light.

  For example, as shown in FIG. 5, a part of the light L of the headlamp of the following vehicle that has entered the lamp chamber S is reflected by the light emitting surface 20c of the plate-like light emitter 20C, as indicated by reference numeral L1. As shown by the symbol L1 ″, most of the light passes through the plate-like light emitter 20C (the back side electrode layer 27A). The light L1 reflected by the light emitting surface 20c of the plate-like light emitter 20C is indicated by the symbol L2. As described above, a part of the light is reflected by the light emitting surface 20d of the plate-like light emitter 20D, but most of the light passes through the plate-like light emitter 20D (the back side electrode layer 27A thereof) as indicated by reference numeral L2 ″.

  Therefore, the light L2 toward the driver of the following vehicle is reflected by the light L of the headlamp of the following vehicle being sequentially reflected by the light emitting surface 20c of the plate-like light emitting body 20C and the light emitting surface 20d of the plate-like light emitting body 20D. In addition to the light whose energy has been reduced due to the reflection of the light, the light corresponding to the light L1 "and L2" transmitted through the plate-like light emitters 20C and 20D has been reduced in energy. It cannot be light.

  FIGS. 7A and 7B are longitudinal sectional views of tail lamps according to third and fourth embodiments of the present invention.

  In these drawings, the tail lamps 10B and 10C are disposed in a lamp chamber S defined by a lamp body 12 and a front cover 14 so that a pair of plate-like light emitters 20A and 20B as light sources face each other vertically. Configured.

  Further, the structure of the plate-like light emitters 20A, 20B is the same as that of the plate-like light emitters 20A, 20B (see FIG. 3) constituting the tail lamp 10 of the first embodiment, and the duplicate description thereof is omitted. .

  Further, in the tail lamp 10B, the light emitting surface 20b is inclined at an angle of 45 degrees with respect to the axle X below the plate-like light emitting body 20A disposed horizontally above the lamp chamber S with the light emitting surface 20a facing downward. The plate-like light emitter 20B is arranged so as to face upward.

  For this reason, when the tail lamp 10B is turned on, the light emission surface 20b of the upper plate-like light emitter 20A appears to be reflected on the light emission surface 20b of the lower plate-like light emitter 20B. Get out.

  On the other hand, in the tail lamp 10C, the light emitting surface 20a is inclined at an angle of 45 degrees with respect to the axle X above the plate-like light emitter 20B disposed horizontally below the lamp chamber S with the light emitting surface 20b facing upward. The plate-like light emitter 20A is arranged so as to face downward.

  For this reason, when the tail lamp 10C is turned on, the light emission surface 20b of the lower plate-like light emitter 20B appears to be reflected on the light emission surface 20a of the upper plate-like light emitter 20A. Get out.

  Further, as shown in FIGS. 7A and 7B, the light L of the headlamp of the following vehicle is reflected by the light emitting surface 20b of the light emitting body 20B (the light emitting surface 20a of the light emitting body 20A), and then the light emitting body 20A. The light-emitting surface 20a (the light-emitting surface 20b of the light-emitting body 20B) is reflected, and further reflected by the light-emitting surface 20b (the light-emitting surface 20a of the light-emitting body 20A) of the light-emitting body 20B. The energy of the light is weakened by reflection, and it does not become glare light for the driver of the following car.

  8A to 8D are longitudinal sectional views of tail and stop lamps according to fifth, sixth, seventh and eighth embodiments of the present invention.

  In these drawings, the tail and stop lamps 10D to 10G are arranged such that a pair of plate-like light emitters 20A and 20C as light sources are vertically opposed in a lamp chamber S defined by a lamp body 12 and a front cover 14. It is arranged and configured.

  The plate-like light emitters 20A and 20C have the same structure as the plate-like light emitters 20A and 20C (see FIGS. 3 and 6) constituting the tail lamp 10 and the tail-and-stop lamp 10A of the first and second embodiments. They are the same, and redundant description thereof is omitted.

  In the tail-and-stop lamp 10D shown in FIG. 8 (a), the light emitting surface 20c is disposed below the plate-shaped light emitter 20A disposed horizontally above the lamp chamber S with the light emitting surface 20a facing downward. On the other hand, the plate-like light emitter 20C is arranged so as to incline at an angle of 45 degrees and face upward.

  Further, an LED 28 as a second light source is disposed behind the lower transparent plate-like light emitter 20C.

  For this reason, when the tail lamp is turned on, the light emission surface 20c of the lower plate-like light emitter 20C appears to be reflected in the light emission surface 20c of the lower plate-like light emitter 20C.

In addition, when the stop lamp is lit, the light emitting surface 20c of the plate-like light emitting body 20C emits red light, and in addition to the red light emission of the light emitting surface 20a of the upper light emitting body 20A appearing on the light emitting surface 20c, Since the light emitted from the LED 28 behind the plate-like light emitting body 20C can be seen through, the stop lamp emits a sense of depth.
In the tail and stop lamp 10E shown in FIG. 8 (b), the light emitting surface 20c is disposed above the plate-like light emitter 20A disposed horizontally below the lamp chamber S with the light emitting surface 20a facing upward. The plate-shaped light emitter 20C is arranged so as to be inclined downward by 45 degrees with respect to the surface.

  For this reason, the light emission surface 20c of the upper plate-like light emitter 20C appears to be reflected on the light emission surface 20a of the lower plate-like light emitter 20A, thereby giving a sense of depth to the light emission of the tail lamp 10C.

  Further, an LED 28 as a second light source is disposed behind the lower transparent plate-like light emitter 20C.

  For this reason, when the tail lamp is turned on, the light emission of the light emitting surface 20a of the lower light emitter 20A is reflected on the light emitting surface 20c of the upper plate-shaped light emitter 20C, thereby giving a sense of depth to the light emission of the tail lamp.

Further, when the stop lamp is lit, the light emitting surface 20c of the plate-like light emitter 20C emits red light, and the light emission surface 20c appears to reflect the red light emission of the light emitting surface 20a of the lower plate-like light emitter 20A. Since the light emitted from the LED 28 behind the plate-like light emitter 20C can be seen through, the stop lamp emits light with a sense of depth.
In the tail-and-stop lamp 10F shown in FIG. 8 (c), the light emitting surface 20a is disposed on the axle X above the plate-like light emitter 20C disposed horizontally below the lamp chamber S with the light emitting surface 20c facing upward. On the other hand, the plate-like light emitter 20A is arranged so as to incline at an angle of 45 degrees and face downward.

  For this reason, when the tail lamp is turned on, the light emission surface 20c of the lower plate-like light emitter 20C appears to be reflected on the light emission surface 20a of the upper plate-like light emitter 20A, thereby giving a sense of depth to the light emission of the tail lamp.

  When the stop lamp is lit, the light emitting surface 20a of the plate-like light emitter 20A emits red light, and the light emitting surface 20a transmits the red light emitted from the light emitting surface 20c of the lower plate-like light emitter 20C and the plate-like light emitter 20C. Since the red light emitted from the LED 28 appears to be reflected, the stop lamp emits a sense of depth.

  In the tail-and-stop lamp 10G shown in FIG. 8 (d), the light emitting surface 20a is disposed below the plate-like light emitting body 20C disposed horizontally above the lamp chamber S with the light emitting surface 20c facing downward. The plate-shaped light emitter 20A is arranged so as to be inclined at an angle of 45 degrees with respect to the upper surface.

  For this reason, when the tail lamp is turned on, the light emission surface 20c of the upper plate-like light emitter 20C appears to be reflected on the light emission surface 20a of the lower plate-like light emitter 20A.

  When the stop lamp is lit, the light emitting surface 20a of the plate-like light emitter 20A emits red light, and the light emitting surface 20a transmits the red light emitted from the light emitting surface 20c of the upper plate-like light emitter 20C and the plate light emitter 20C. Since the red light emitted from the LED 28 appears to be reflected, the stop lamp emits a sense of depth.

  In the first and second embodiments described above, when the indicator lamps are directly opposed, the light emission of the other adjacent light emitting surface is reflected on each light emitting surface of the two adjacent plate-like light emitters. So that the light emitting surfaces of the two adjacent plate-like light emitters are arranged at 90 degrees, and in the third to eighth embodiments described above, when the indicator lamps are directly opposed, The light emitting surfaces of two adjacent plate light emitters are arranged at 45 degrees so that the light emission of the other light emitting surface adjacent to each other appears on one light emitting surface of the plate light emitter. Any angle can be used as long as the light emission of the light emitting surface of the other plate-shaped light emitter adjacent to the light emitting surface of the one plate-shaped light emitter is reflected when the marker lamp is directly opposed. .

  Further, in the above-described embodiment, a description is given of a marker lamp in which two adjacent plate-like light emitters are accommodated in a lamp chamber. However, a marker lamp in which three or more plate-like light emitters are adjacently arranged in a lamp chamber. It goes without saying that can be applied as well.
