Abstract
A vehicle light () produces low-beam output using generally spherical distribution light source () with increased efficiency. The vehicle light () includes transmissive lens () through which light exits vehicle light (); concave reflector (); light occluding member () defining first sub-reflector (); cut-off edge (); and second sub-reflector (). Concave reflector () extends upward above light occluding member () and directs low-beam light toward transmissive lens (). Light occluding member () is disposed horizontally proximate a longitudinal axis of the vehicle light and low-beam light is reflected between concave reflector () and light occluding member () toward transmissive lens (). A second sub-reflector () disposed below generally spherical distribution light source () has a concave reflecting surface (), preferably shaped as a wedge of a sphere, to reflect low-beam light, emitted downwardly from generally spherical distribution light source (), towards concave reflector ().
