  • Patent number: 8439520
    Abstract: A collimated light source with solid-state light emitters in which the solid-state light emitter is optically coupled to a high refractive index reflector optic, which reduces the cone angle of the light input to the reflector optic. Reducing the cone angle allows the reflective surface of the reflector optic to be reduced in size compared with a conventional reflector in air. The solid-state light emitter is mounted near the light output surface to further reduce the size of the collimated light source. The highly collimated light beams of different colors generated by multiple collimated light sources enable the lighting assembly to use a decussate optical filter having dichroic filter elements to combine the light beams to provide the compact lighting assembly having a configurable output light color.

  • Patent number: 8439536
    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.
