方に導かれる。FIG. 1 is a cross-sectional view of the rear lamp viewed from above the vehicle,
FIG. 2 is a sectional view taken along line AA. 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. The light from the bulb 2 is reflected by the parabolic reflector 1a in parallel to the opening of the housing 1 as shown in the figure. Further, a bulb 2 as a light source is attached to a rear end of the housing 1 via a bracket 3, and light emitted from the bulb 2 is reflected by a reflector.
The light is reflected by 1a and guided toward the opening of the housing 1. A red transparent lens 4 is mounted on the front surface of the housing 1 so as to cover the opening thereof.

る。Reference numeral 5 denotes a hollow hemispherical concealing member 5 that covers the front part of the bulb 2, and a rod-shaped mounting member 6 is integrally provided on the concealing member 5 so as to protrude as shown in FIG. When the mounting member 6 is fitted to the bracket 3, the concealing member 5 is held at the illustrated position. This concealing member 5 is formed of a white translucent member such as frosted glass, for example.
It is attached to the front of a line connecting the valve 2 and the peripheral portion 1b of the reflector 1a. Here, the peripheral portion 1b of the reflector 1a is the outermost portion 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, since the bulb 2 is covered with the white concealing member 5, the position where the light source is located looks dark through the lens 4. There is no. Also, when the bulb 2 is turned on, of the light from the bulb 2, the light emitted from the front of the reflector 1 a is guided to the lens 4 side via the concealing member 5, so that the position where the bulb 2 is located when viewed from the outside Does not have high brightness.

材６は十分細いので照明光に何ら悪影響を与えない。Further, since the concealing member 5 is provided ahead of a line connecting the bulb 2 and the peripheral edge 1b of the reflector 1a,
Emission of light from the bulb 2 to the reflector 1a is not hindered by the concealing member 5, and there is no shadow on the light emitted to the outside. Furthermore, the light from the bulb 2 is slightly blocked by the mounting member 6 of the concealing member 5, but the mounting member 6 is sufficiently thin to have no adverse effect on the illumination light.

えばヘッドランプに適用することもできる。In addition, since only the bulb 2 is concealed, the parabolic surface of the reflector 1a can be seen through the lens 4 better than when a translucent member is arranged on the entire inner surface side of the lens 4.
The lamp gives a sense of depth and looks good. The concealing member 5 is not limited to white as long as it is translucent, and may be, for example, the same color as the lens. In the above description, an example is shown in which the reflector is integrally formed on the inner surface of the housing. However, the present invention can be applied to a housing having a reflector separate from the housing. Further, the rear lamp has been described, but the invention can be applied to, for example, a headlamp.

が可能となる。G. Effects of the Invention According to the present invention, a translucent concealing member that covers the front of the light source is provided in front of the line connecting the light source and the peripheral edge of the reflector. The lighted portion does not look dark and looks the same color as the surroundings, and when the light source is lit, the brightness of the portion where the light source is located and its surroundings are almost the same. Therefore, the appearance of the lamp when the light source is turned off and when it is turned on can be improved with a simple configuration without any adverse effect on the illumination light.
