Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a vehicular lamp, and more particularly to a lamp effective for preventing false lighting.

[Problems to be solved by conventional techniques and devices]

FIG. 9 shows a conventional lamp with a reflector, in which a reflector 4 is formed on the inner peripheral surface of a lamp body 2, and light from a bulb 6 which is a light source arranged in front of the reflector 4 is reflected by the reflector 4. The front lens 8 attached to the front opening of the lamp body emits light.

However, in the above-mentioned conventional technique, the entire front lens 8 attached to the front opening of the lamp body emits light, and the effective light emitting area of the lens 8 is wide. Moreover, the lamp chamber space around the bulb 6 is made large in order to prevent the heat of the bulb 6, that is, the vertical height H of the lamp body 2 is made high, and the front lens 8 is made large accordingly. Therefore, as shown by reference numeral l in FIG. 9, external light such as sunlight enters the lamp body 2 through the lens 8 and is reflected by the reflector 4 to cause the lens 8 to emit light, so-called pseudo lighting. Is a problem. In order to prevent this pseudo lighting, the depth of the lamp body 2 may be made sufficiently large, but there is a restriction from the viewpoint of downsizing the lamp.
