A lamp chamber 11 is formed between the lamp body 9 and the translucent cover 10, and a lamp unit 12 that illuminates the front of the lamp is housed in the lamp chamber 11. The lamp unit 12 guides the light from the LED light source 13 with the light guide 14, reflects the light emitted from the light guide 14 with the main reflector 15, and passes the reflected light through the diffuser lens 16 and the inner lens 17 to cover the translucency. It is designed to emit light from 10 to the front of the lamp (rear of the vehicle).

The second lamp 5 is provided with a translucent cover 20 on the front surface of the lamp body 19, and a lamp unit 22 for illuminating the front of the lamp is housed in a lamp chamber 21 between the lamp body 19 and the translucent cover 20. Similar to the lamp unit 12 of the first lamp 3, the lamp unit 22 guides the light from the LED light source 23 by the light guide 24, reflects the light emitted from the light guide 24 by the reflector 25, and reflects the reflected light by the diffuser lens 26. And through the inner lens 27, the light is emitted from the translucent cover 20 to the front of the lamp.

In the first and second lamps 3 and 5, the translucent covers 10, 20 and / or the inner lenses 17 and 27 of the lamps 3 and 5 are red so that the functional colors as tail and stop lamps, that is, red light can be emitted. It is molded with the transparent resin of. The translucent cover 10 of the first lamp 3 is formed so that the extension portion 29 extends rearward from the front surface of the lamp at the inner end in the vehicle width direction, and the light emitting portion 30 is at the rear end of the extension portion 29. It is provided so as to overhang on the lamp 5 side. When the translucent cover 10 is red, the extending portion 29 and the light emitting portion 30 are also integrally molded with the same red resin.

The back surface of the light emitting portion 30 is textured, and the textured portion 31 makes the light emitting portion 30 opaque (see FIG. 1). Then, the textured portion 31 emits light from the light guide 24 into the lamp chamber 11, and illuminates the gap 7 between the first lamp 3 and the second lamp 5 from a position behind the front of the lamp. ing. The textured portion 31 is a portion that makes the light emitting portion 30 opaque, and the processing method thereof is not particularly limited, and a method of transferring the rough surface of the mold surface to a transparent resin and polishing the transparent resin after molding. , Painting, method of making opaque by chemical treatment, etc. can be exemplified.

As shown in FIGS. 2 and 3, the lamp unit 12 of the first lamp 3 includes, in addition to the main reflector 15, a sub-reflector 32 that reflects the light from the light guide 14 toward the light emitting unit 30. In this embodiment, the sub-reflector 32 is integrally provided inside the main reflector 15 in the vehicle width direction, but the two reflectors 15 and 32 can be separated and provided separately. Both the main reflector 15 and the sub-reflector 32 are arranged below the light guide 14, and are formed so that the main reflector 15 spreads toward the front of the lamp and the sub-reflector 32 spreads toward the light emitting portion 30.

The light guide 14 is formed with a first step 33 that emits light guided inside the light guide 14 toward the main reflector 15 and a second step 34 that emits light inside the light guide toward the sub-reflector 32. The first step 33 is formed on the upper surface of the light guide 14 over substantially the entire length, and the second step 33 is formed on the side surface or the front surface thereof only at the distal end portion of the light guide 14. Therefore, at the distal end of the light guide 14, the first and second steps 33 and 34 are arranged at different positions in the circumferential direction. The main reflector 15 is formed with a notch 35 for passing the light from the second step 34 through the sub-reflector 32. Further, the tip surface of the light guide 14 has a curved surface 36 that prevents internal light from escaping to the outside.

In the rear combination lamp 1 having the above configuration, when the tail & stop lamp 6 is turned on, the light from the LED light source 13 is guided by the light guide 14, and most of the light guide is emitted from the first step 33 toward the main reflector 15. The reflected light of the main reflector 15 is emitted from the translucent cover 10 to the front of the lamp through the diffuser lens 16 and the inner lens 17. Further, a part of the light guide by the light guide 14 is emitted from the second step 34 toward the sub-reflector 32, the reflected light of the sub-reflector 32 is incident on the textured portion 31 of the translucent cover 10, and the light emitting portion 30 It emits light.

At this time, since the light passing through the textured portion 31 is gentler or softer than the light transmitted through the conventional transparent portion, the gap 7 between the first lamp 3 and the second lamp 5 is filled with these lamps 3, By illuminating with the same brightness as 5, it is possible to eliminate the discontinuity from the appearance of the two lamps 3 and 5 and improve the appearance of the tail & stop lamp 6. In particular, by forming the light emitting portion 30 on a part of the red translucent cover 10, the color uniformity of the tail & stop lamp 6 is also increased. Further, since the first and second steps 33 and 34 are provided at different positions in the circumferential direction at the distal end of the light guide 14, the light from one LED light source 13 is effectively used to the front of the lamp. And can be distributed to the light emitting unit 30.

In the rear combination lamp of the second embodiment, as shown in FIG. 4, the light emitting unit 40 is provided on the inner lens 17 of the first lamp 3. An extension 39 extends to the rear of the lamp at the inner end of the inner lens 17 in the vehicle width direction, and a light emitting portion 40 projects toward the second lamp 5 at the rear end of the extension 39. Then, an opaque textured portion 41 is provided on the front surface or the back surface of the light emitting portion 40, and also on the side surface of the extending portion 39 if necessary, and the light emitted from the second step 34 of the light guide 14 causes the sub-reflector 32. It is incident on the light emitting unit 40 through the light emitting unit 40, and the gap 7 between the two lamps 3 and 5 is illuminated from a position behind the front surface of the lamp by the light emitted from the textured portion 41.

Therefore, according to the rear combination lamp of the second embodiment, especially when the colorless translucent cover 10 is used and the inner lens 17 is colored red, the gap 7 looks good with the red light from the light emitting unit 40. It can be illuminated well. Further, since the inner lens 17 is covered with the translucent cover 10 from the front of the lamp, there is an advantage that the light emitting portion 40 is not easily contaminated by mud or oil smoke. Other configurations and effects are the same as in Example 1.

In the rear combination lamp of the third embodiment, as shown in FIG. 5, the light emitting unit 50 is provided on the opaque lamp body 9. In the lamp body 9 of the first lamp 3, an opening 52 is formed in a side wall 49 on the inner side in the vehicle width direction, and a cap member 53 made of a red transparent resin so as to cover the opening 52 from the outside of the lamp chamber 11. Is fixed by welding or adhesion. The cap member 53 protrudes from the side wall 49 toward the second lamp 5, and the front portion located behind the gap 7 serves as the light emitting portion 50. On the back surface of the light emitting portion 50, a textured portion 51 that makes the light emitting portion 50 opaque is provided, and a reflector 54 is arranged inside the cap member 53 so as to diagonally face the textured portion 51. ..

Then, a smooth exit surface 55 is formed at the tip of the light guide 14, and the light guided through the inside of the light guide 14 is emitted from the exit surface 55 toward the opening 52, and is textured through the reflector 54. When incident on 51, the light emission of the light emitting unit 50 illuminates the gap 7 between the first and second lamps 3 and 5 from a position behind the front surface of the lamp. Therefore, according to the rear combination lamp of the third embodiment, in particular, the opaque side wall 49 of the lighting fixture body 9 functions as a shade of the light emitting portion 50, so that the mixing of light leaked from the translucent cover 10 is suppressed and controlled. The gap 7 can be illuminated with good appearance by the light.

In the rear combination lamp of the fourth embodiment, as shown in FIG. 6, the first lamp 3 includes a dedicated light source 58 for causing the light emitting unit 30 to emit light. The dedicated light source 58 is mounted on the substrate 59 and is optically shielded from the lamp unit 12 of the first lamp 3 by the light-shielding wall 60 of the substrate 59. Then, the light from the dedicated light source 58 is reflected by the reflector 61, the reflected light is incident on the textured portion 31, and the light from the light emitting portion 30 illuminates the gap 7 between the two lamps 3 and 5. ing. Therefore, according to the rear combination lamp of the fourth embodiment, the gap 7 can be illuminated relatively brightly by using a dedicated light source 58 separate from the light source 13 of the lamp unit 12.
