LED PLANAR LIGHT SOURCE AND LOW-PROFILE HEADLIGHT CONSTRUCTED THEREWITH

摘要

A light source ( 10 ) includes a light emitting semiconductor device ( 12 ). A support substrate ( 14 ) has a generally planar reflective surface ( 28 ) that supports the semiconductor device ( 12 ). The light emitting semiconductor device heat sinks via the support substrate. A curved reflector ( 16 ) has a concave parabolic reflective surface. The light emitting semiconductor device ( 12 ) is arranged between the support substrate ( 14 ) and the curved reflector ( 16 ). The support substrate ( 14 ) and the curved reflector ( 16 ) together define a light aperture ( 18 ) through which light produced by the light emitting semiconductor device ( 12 ) passes.
