Abstract
A vehicle light can include a matrix type semiconductor light source, an imaging lens and a reflector. The light source can project an enlarged matrix light on the reflector via the imaging lens. The reflector can include a matrix reflex surface having horizontal curvatures. Each of the horizontal curvatures of the reflex surfaces arranged in columns can be configured such that the corresponding column light is extended gradually in a wider range as the corresponding column light approaches from a central column light toward both edge column lights. Accordingly, a magnification of light projected from the reflector can become gradually large as approaching from the central column toward both edge columns. Thus, the disclosed subject matter can provide vehicle headlights that can form favorable light distribution patterns for a low beam and a high beam having a bright central portion in a wide range of a smooth light distribution pattern.
