Abstract: A vehicular signal lamp providing a uniformly bright appearance even when the lamp is observed in a lateral direction. A reflecting surface of a reflector is composed of a plurality of reflecting elements for diffusing and reflecting in right and left directions the light from a light source bulb. A left direction maximum diffusion angle of the respective reflecting elements is set to a smaller value the nearer the reflecting element is located to the left end portion of the reflecting surface, and a right direction maximum diffusion angle R of the respective reflecting elements is set to a smaller value the nearer the reflecting element is located to the right end portion of the reflecting surface. Thereby, when the light is observed in a lateral direction by moving the viewing position from the light front direction to the right or left, the entire reflecting surface appears bright within a certain light viewing angle.

Abstract: The luminaire has a molded reflector body (1) comprising a reflective coating (3) with light reflective particles (10) and a binder (11) and having a substrate side (12) and an outer surface (13). The coating (3) has a smooth optical waveguiding surface due to the absence of particles (10) at its outer surface (13) and to the light-transmission properties of the binder (11). Owing to these properties, the coating (3) has a high degree of specular reflection, thereby both increasing the lumen output ratio and improving the light directional properties of the luminaire.

Horizontal cut line forming steps 12aH out of a plurality of light distribution steps 12a constituting a reflecting surface 12 extend over such upper and lower areas as to interpose phantom lines Lh1, Lh2 on the reflecting surface 12 therebetween. The phantom lines will correspond to the horizontal cut lines.

As a result, the horizontal cut line forming steps 12aH can be reduced into a single step without steps and bends.
