Vehicle low-beam headlamp with concave reflector and sub-reflector having two concave reflecting surfaces

Fuente: WIPO "rice"
A vehicle light (1, 11) produces low-beam output using generally spherical distribution light source (7) with increased efficiency. The vehicle light (1) includes transmissive lens (2) through which light exits vehicle light (1); concave reflector (3); light occluding member (100) defining first sub-reflector (6); cut-off edge (4); and second sub-reflector (5). Concave reflector (3) extends upward above light occluding member (100) and directs low-beam light toward transmissive lens (2). Light occluding member (100) is disposed horizontally proximate a longitudinal axis of the vehicle light and low-beam light is reflected between concave reflector (3) and light occluding member (100) toward transmissive lens (2). A second sub-reflector (5) disposed below generally spherical distribution light source (7) has a concave reflecting surface (18, 18a, 18b), preferably shaped as a wedge of a sphere, to reflect low-beam light, emitted downwardly from generally spherical distribution light source (7), towards concave reflector (3).
