Vehicular lamp |
摘要 |
A vehicular lamp in which a luminous flux utilization factor is enhanced by a structure of a light-emitting element that is disposed to face forward with respect to a vehicular lamp and covered from its front side with a translucent member. The circumferential region of the translucent member forms a reflected light control portion that allows light from the light-emitting element which has impinged on the translucent member to be internally reflected by the rear face of the translucent member and turned into parallel light which travels forward, and the reflected light control portion further allows the parallel light to emit forward from the front face of the reflected light control portion.
