Vehicular Lamp
First Claim
1. A vehicular lamp comprising:
- a plurality of first semiconductor light emitting elements disposed in a spaced manner;
a plurality of light guide portions which respectively correspond to the plurality of first semiconductor light emitting elements, and to which first emission light that is emitted from the first semiconductor light emitting elements enters; and
a first reflecting portion for reflecting second emission light, which is emitted from the first semiconductor light emitting elements but does not enter the light guide portions, toward a radiation direction, whereinthe plurality of light guide portions are provided spacedly in a first direction that intersects the radiation direction, and configured such that the first emission light entering therein is guided toward the radiation direction, andthe first reflecting portion is configured such that at least a portion of the reflected second emission light passes therethrough and radiates from an area between the plurality of light guide portions.

Abstract
A vehicular lamp including a plurality of first semiconductor light emitting elements and a plurality of first light guide portions respectively corresponding to the first semiconductor light emitting elements, so that first emission light emitted from the first semiconductor light emitting elements enters the first light guide portions. Second emission light emitted from the first semiconductor light emitting elements but does not enter the first light guide portions is reflected in a radiation direction of the lamp by respective segmented reflecting portions. The first light guide portions are provided spacedly in a first direction that intersects the radiation direction and configured such that the first emission light entering therein is guided in the radiation direction. The segmented reflecting portions are configured such that at least a portion of the reflected second emission light passes therethrough and radiates from an area between the plurality of first light guide portions.
