Abstract

PROBLEM TO BE SOLVED: To provide a lamp device for a vehicle of which, a luminous area of each lamp can be enlarged, and does not become an emergency lighting even in a daytime. SOLUTION: As the lamp device has both of a red light source R1 and a yellow light source Y, it becomes a tail lamp lighting in red color when only the red light source R1 is lighted, and becomes a turn lamp lighting in amber color when both of the red light source R1 and the yellow light source Y is lighted. As one lamp is functioning as a tail lamp, a turn lamp, and a stop lamp, a luminous area is enlarged, and the visibility of the lamp is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a tail lamp,
The present invention relates to a vehicle lamp device such as a turn lamp and a stop lamp.

[0002]

2. Description of the Related Art A lamp device called a so-called rear combination lamp is attached to a rear portion of an automobile. This type of lamp device is combined with a tail lamp, a turn lamp, and a stop lamp (as similar technologies, Japanese Utility Model Laid-Open No. 6-36116, Japanese Utility Model Laid-Open No.
No. 69803).

[0003]

However, in such a conventional lamp device, since there are many types of lamps to be combined, the light emitting area of each lamp is reduced accordingly. In addition, stop lamp and turn lamp,
Although the tail lamps are lit during the daytime, the tail lamps are of the type that is lit only at night. Therefore, the tail lamps that are not always lit during the daytime stand out, lack a sense of unity with other lamps, and improvements are desired.

The present invention has been made by paying attention to such a conventional technique, and provides a vehicular lamp device which can increase the light emitting area of each lamp and does not remain unlit even in the daytime. .

[0005]

According to the first aspect of the present invention,
Inside a housing attached to the rear part of the vehicle, two reflectors integrated with or separate from the housing are provided side by side,
A structure in which a red light source is mounted on one reflector, a yellow light source is mounted on the other reflector, and a colorless outer lens is mounted on the opening of the housing. When the lamps are lit simultaneously, the lamp emits amber light.

According to the first aspect of the present invention, since both the red light source and the yellow light source are provided, if only the red light source is turned on, all the large outer lenses emit a red light such as a tail lamp or a stop lamp. When both the red light source and the yellow light source are turned on, all of the large outer lenses become lamps such as amber light emitting turn lamps. With one lamp device, all of the large outer lenses can emit light with the three functions of the tail lamp, the turn lamp, and the stop lamp. Therefore, the light emitting area of the outer lens is increased, and the visibility of the lamp is improved.
In addition, at least it has a turn lamp function and is lit even in the daytime, so there is a sense of unity with other stop lamps.

According to the second aspect of the present invention, a shade is provided between the red light source and the yellow light source.

According to the second aspect of the invention, there is no light that directly enters from one light source to the other light source side, and is once reflected by its own reflector and then spread to the other light source side. No light emitting state is obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A preferred embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows a rear combination lamp 3 in which an upper lamp 1 and a lower lamp 2 are combined. The upper lamp 1 is a lamp device according to the present invention.

Each of the upper lamp 1 and the lower lamp 2 has two reflectors 4a, 4b and a reflector 5a,
The housings 4 and 5 have a structure in which the housings 5b are connected side by side. The rear openings of the housings 4 and 5 are closed by colorless outer lenses 6 and 7, respectively. A partition wall 8 is formed between the upper lamp 1 and the lower lamp 2,
No light leaks.

At the bottom of each reflector 4a, 4b of the upper lamp 1, a red light source R1 and a yellow light source Y are mounted, respectively. Shades 9 are set up inside red light source R1 and yellow light source Y, respectively. Red light sources R2 and R3 are attached to the bottoms of the reflectors 5a and 5b of the lower lamp 2, respectively.

FIG. 4 shows a lighting pattern of the rear combination lamp 3. First, in (A), only the red light source R1 of the upper lamp 1 was turned on, and only one red light source R2 of the lower lamp 2 was turned on. Then, the upper lamp 1 and the lower lamp 2 become large tail lamps that emit red light as a whole, and the visibility is improved. Even with the upper lamp 1 alone, the red light emitted from the red light source R1 is once reflected by the reflector 4a and reaches the reflector 4b side of the yellow light source Y, so that the light emitting area is increased.

Next, in the state (A), when the driver steps on the brake, another red light source R3 of the lower lamp 2 is pressed.
, And the lower lamp 2 becomes a stop lamp having a red light emission pattern brighter than the upper lamp 1. The upper lamp 1 remains a tail lamp.

Then, when the driver operates the turn signal switch in the state (A), the yellow light source Y of the upper lamp 1 is also turned on and is simultaneously turned on with the red light source R1, so that the upper lamp 1 is amber. It becomes a turn lamp with a light emission pattern of (orange). At this time, since the shade 9 is provided between the red light source R1 and the yellow light source Y, the red light or the yellow light emitted from the red light source R1 or the yellow light source Y may directly enter the opposite reflectors 4a and 4b. Not
The light is once reflected by its own reflectors 4a and 4b and then spreads out to the opposite side, so that a uniform and uniform light emitting state can be obtained. Also, since the upper lamp 1 has at least a turn lamp function, it will emit light even in the daytime,
In the daytime, it is not always turned off, and there is a sense of unity with the lower lamp 2.

In this embodiment, the housings 4, 5
Although the example provided with the reflectors 4a, 4b, 5a, and 5b integral with the above, the present invention may be applied to a type provided with another reflector inside the housings 4, 5. The upper lamp 1 and the lower lamp 2 both have two reflectors 4.
a, 4b and the housings 4, 5 having a structure in which the reflectors 5a, 5b are connected side by side have been described. However, the present invention is not limited to the side by side, and may be vertical or oblique.

Further, the setting directions of the respective central axes formed on the reflectors 4 and 5 may be arranged in parallel or may cross each other. If the direction is set to cross, color unevenness is less likely to occur.

[0017]

According to the present invention, since both the red light source and the yellow light source are provided, if only the red light source is turned on, the tail lamp emits red light, and both the red light source and the yellow light source can be turned on. For example, it becomes a turn lamp emitting amber light. Since one lamp has a function of a tail lamp and a turn lamp stop lamp, the light emitting area is increased, and the visibility of the lamp is improved. In addition, at least it has a turn lamp function and it lights up even in the daytime,
There is a sense of unity with other lamps.
