Abstract:
A signal lamp for vehicles comprising:a light source;a reflector having a reflective surface for reflecting forward light emitted from the light source, the reflective surface being composed of a plurality of diffusing reflection elements, each reflection element comprising a reflecting region which reflects light emitted from the light source in an optical axis direction of the reflector, where an area ratio of the reflecting region, for a particular reflection element, to a total area of said particular reflection element is based on the illuminance of said particular reflection element of said plurality of diffusing reflection elements, with respect to the incident light emitting from the light source, such that the area ratio of the reflecting region to the reflection element is lower for reflection elements with a high illuminance than for reflection elements with a low illuminance; anda lens arranged in the front of the reflector.
