Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rear combination lamp mounted on a rear panel of an automobile.

[0002]

2. Description of the Related Art Conventionally, rear combination lamps are:
A stop lamp, a turn lamp, a back lamp and a tail lamp, each lamp being colored by an outer lens, an inner lens or a colored cap lamp, respectively, for example, the stop lamp and the tail lamp are red, the turn lamp is yellow, and The back lamp is colored white. Each of the lamps is divided so as to prevent light of another color from leaking, and each of the lamps is independently emitted by a bulb (incandescent lamp).

FIGS. 11 and 12 show an example of a rear combination lamp. That is, in FIG. 11, the rear combination lamp 1 is configured to include a tail stop lamp 2 serving also as a tail lamp and a stop lamp, a turn lamp 3, and a back lamp 4 in a rear region of the vehicle. I have.

Further, a rear combination lamp 1
As shown in the sectional view of FIG. 12, the lamps 2, 3, and 4 are mounted in a mounting portion 5a formed on the rear panel 5 of the automobile.
, A housing 7 partitioned into sections corresponding to the housing 6, a valve 7 disposed in each section of the housing 6, and a housing 6
And an outer lens 8 attached so as to cover the opening.

Here, the lead wire 7a of each valve 7
Is drawn out to the rear side of the rear panel 5 through a through hole 5b provided in the rear panel 5 of the automobile, and is connected to a wire harness (not shown) via a connector (not shown). . Here, the rear side of the rear panel 5 is entirely covered with the trim 9.

In the illustrated case, the outer lens 8 is colored red as shown by hatching in the upper tail stop lamp 2 and colorless, that is, transparent or transparent, in the lower turn lamp 3 as shown in the figure. It is formed translucent. On the other hand, the bulb 7 corresponding to the turn lamp 3
Is provided with a yellow colored cap 7b on the front surface thereof.

According to the rear combination lamp 1 configured as described above, each bulb 7 in the section of the housing 6 corresponding to each of the lamps 2, 3, and 4 emits light, so that each of the lamps 2, 3 and 4 respectively. Lights up. That is, when the bulb 7 corresponding to the tail stop lamp 2 emits light, the white light from the bulb 7 passes through the red portion of the outer lens 8 and turns on red. When the bulb 7 corresponding to the turn lamp 3 emits light, white light from the bulb 7 is supplied to the colored cap 7b.

[0008]

However, in the rear combination lamp 1 configured as described above, a bulb 7 of a normal heating wire type is used as a light emitting source. For this reason, the depth in the front-rear direction is large, and therefore, a relatively large space is required on the rear side of the rear part of the vehicle, so that the trim 9 protrudes largely into the cabin, and the trunk volume of the vehicle is reduced. There was a problem. In addition, since the valve 7 has a relatively short life and consumes a large amount of power, it needs to be replaced in a relatively short period of time and has a problem that a large capacity battery is required.

Further, the bulb 7 takes a long time to emit light, and in particular, in the case of a stop lamp, the lighting of the stop lamp informs the following vehicle of the brake timing.
A faster emission rate is desired. In addition, each lamp 2,
Since the housings 3 and 4 are each limited to emitting light of a single color by dividing the housing, the design is limited, and the turn lamps 3 and the back lamps 4 are particularly tail-stop lamps 2. However, there is a problem that the area is smaller than that of the above and the visibility is slightly lowered.

[0010] In view of the above, the present invention can be made thin with a simple structure, and has a low power consumption, a long life, a high light emission speed, and a variety of designs. It is intended to provide a combination lamp.
