Abstract
A signal lamp for vehicles has a reflector that acts to diffuse light from a light source within the lamp. The reflector is made up of multiple diffusing reflective elements having a reflecting region that reflects light emitted from the light source in a direction of an optical axis of the lamp. A lens is positioned in front of the reflector. The reflecting region of each diffusing reflective element is varied, such that an area ratio of the reflecting region for portions of the reflector with a high reflective illuminance is less than other portions having lower illuminance.
