Abstract:
1. A light source unit for a vehicular lamp, comprising: a semiconductor light-emitting element disposed on an optical axis of said light source unit with its light output directed in a predetermined direction substantially orthogonal to said optical axis, and a reflector provided on a forward side in said predetermined direction with respect to said semiconductor light-emitting element, said reflector having a first reflecting surface to collect and reflect a light emitted from said semiconductor light-emitting element forward in a direction of said optical axis, said first reflecting surface being formed in such a manner that a distance in said predetermined direction from said semiconductor light-emitting element to said first reflecting surface is 20 mm or less; and a projection lens provided at a predetermined position on a forward side in said direction of said optical axis with respect to said reflector; wherein said reflector further comprises a light control member for shielding a part of light reflected by said first reflecting surface, said light control member being provided at a predetermined position on a forward side in said direction of said optical axis with respect to said semiconductor light-emitting element; wherein said first reflective surface is substantially dome shaped.
