Patent ID: 7255467

Claim:
A vehicular headlamp, comprising: a semiconductor light emitting device facing in a direction substantially perpendicular to a forward direction; a reflector configured in a curved shape having an aperture in a front side to surround said semiconductor light emitting device, wherein said reflector has an optical center thereof in proximity of said semiconductor light emitting device, and reflects light incident from said semiconductor light emitting device toward the front side; and a light transmitting member configured to cover said semiconductor light emitting device, wherein said light transmitting member comprises a rear sealing part shaped like a quarter sphere and a front sealing part shaped such that a radius of curvature of a surface in a cross section parallel to the forward direction is smaller than a radius of curvature of a surface of the rear sealing part, wherein the front sealing part deflects a portion of light generated by said semiconductor light emitting device toward the front side and the rear sealing part transmits a portion of said light generated by said semiconductor light emitting device toward said reflector.
