用される。01 Means for Solving the Problems The present invention will be explained in conjunction with FIG. 1 showing an embodiment of the invention. and a reflector 1a that reflects the light from the light source 2 toward the opening of the lamp housing 1.
The present invention is applied to a vehicle lamp including a lens 4 that covers the entrance portion and transmits the reflected light from the reflector 1a and guides it to the outside.
そして、光源２とリフレクタ１ａの周縁部１ｂとを結ぶ
線よりも前方に、光源２の前部を覆う半透明の隠蔽部材
５を設け、これにより上記問題点を解決する。A translucent concealing member 5 covering the front part of the light source 2 is provided ahead of the line connecting the light source 2 and the peripheral edge part 1b of the reflector 1a, thereby solving the above problem.
Ｅ０作用
半透明の隠蔽部材５が光源２の前部を覆っているので、
光源消灯時には、レンズ４を通して光源２の位置する箇
所が黒ずんで見えることがない。Since the E0 effect translucent concealing member 5 covers the front part of the light source 2,
When the light source is turned off, the area where the light source 2 is located does not appear dark through the lens 4.
また光源点灯時、上記光源光のうちリフレクタ１ａより
も前方に射出される光は、隠蔽部材５を介してレンズ４
に導かれるので、外部から見たとき光源２の位置する箇
所が高輝度となることがない。Further, when the light source is turned on, the light emitted from the light source in front of the reflector 1a is transmitted to the lens 4 through the concealing member 5.
Therefore, when viewed from the outside, the area where the light source 2 is located will not have high brightness.

体に形成されている。FIG. 1 is a cross-sectional view of this rear lamp viewed from above the vehicle, and FIG. 2 is a cross-sectional view taken along the line A--A. Reference numeral 1 denotes a lamp housing (lamp housing) having an opening on the front surface, and a parabolic reflector 1a is integrally formed on the inner surface of the housing 1.

ズ４を透過して外部、すなわち車両後方に導かれる。The parabolic reflector 1a reflects the light from the bulb 2 in parallel to the opening side of the housing 1 as shown. Further, a bulb 2 as a light source is attached to the rear end of the housing 1 via a bracket 3, and the light emitted from the bulb 2 is reflected by a reflector 1a and guided to the opening side of the housing 1. . A red transparent lens 4 is placed on the front of the housing 1 to cover the opening.
is attached, and the light reflected by the reflector 1a is transmitted through this lens 4 and guided to the outside, that is, to the rear of the vehicle.

分である。Reference numeral 5 designates a hollow hemispherical concealing member 5 that covers the front portion of the bulb 2, and a rod-shaped mounting member 6 is integrally provided on this concealing member 5 to protrude as shown in FIG. By fitting this attachment member 6 to the bracket 3, the concealing member 5 is held in the illustrated position. This concealing member 5 is formed of a white semi-transparent member such as frosted glass, and is attached ahead of a line connecting the bulb 2 and the peripheral edge 1b of the reflector 1a. Here, the peripheral edge part 1b of the reflector 1a is the outermost part of the paraboloid that forms the parallel light.

箇所が高輝度になることがない。According to the above configuration, when the rear lamp is viewed from the outside when the bulb 2 is turned off, the bulb 2 is covered with the white concealing member 5, so the area where the light source is located appears dark through the lens 4. Furthermore, when the bulb 2 is turned on, the light emitted from the bulb 2 forward from the reflector 1a is guided to the lens 4 side via the concealing member 5, so the bulb 2 is not visible when viewed from the outside. The location will not have high brightness.

。Furthermore, since the concealing member 5 is provided forward of the line connecting the bulb 2 and the peripheral edge 1b of the reflector 1a, the concealing member 5 prevents the light from the bulb 2 from being emitted to the reflector 1a. There is no problem, and there is no shadow in the light irradiated to the outside.Furthermore, the light from the bulb 2 is somewhat blocked by the mounting member 6 of the concealing member 5, but the mounting member 6 is sufficiently thin so that it does not have any negative effect on the illumination light. not give.

The concealing member is not limited to white, as long as it is semitransparent, and may be the same color as the lens. In the above, the reflector is integrally formed on the inner surface of the housing. Although an example has been shown, the present invention can also be applied to a structure having a reflector separate from the housing. Further, although the description has been made regarding rear lamps, the present invention can also be applied to headlamps, for example.

が可能となる。G3 Effects of the Invention According to the present invention, a translucent concealing member that covers the front part of the light source is provided in front of the line connecting the light source and the peripheral edge of the reflector, so when the light source is turned off, the position of the light source can be seen through the lens. The area where the light source is located does not appear dark and appears to be the same color as the surrounding area, and when the light source is turned on, the area where the light source is located and the area around it have approximately the same brightness. Therefore, it is possible to improve the appearance of the lamp when the light source is turned off and when the light source is turned on with a simple configuration without any adverse effect on the illumination light.
