Motor vehicle headlight according to the projection principle look

机译:汽车大灯按投影原理看

摘要

A projector-type headlamp comprises a concave mirror (6) having a reflecting inner surface (10), a lamp bulb and a convex lens which project forwardly the rays of light emitted from the lamp bulb and reflected at the concave mirror. The reflecting inner surface (10) has formed in at least a portion thereof a light diffusion area (12) consisting of a portion of each of different curved conical surfaces (12c,12d). Since the light diffusion area (12) diffuses light rays at a higher rate in the area (d) near the central portion of the concave mirror (6) than in the peripheral area (c) thereof, it is possible to alleviate the driver's feeling that the luminosity in the hot zone formed near the center of the luminous intensity. distribution pattern is too strong.
