Abstract
A vehicular lamp which radiates light by indirect illumination using a plurality of LED light sources and which has an improved appearance when the lamp is lit. Light from a plurality of LED light sources is formed into parallel light fluxes by a plurality of Fresnel lenses, and the parallel light fluxes are reflected toward the front of the lamp by a segmented reflector. The LED light sources and the lenses are divided into first and second groups which form respective light fluxes directed in orthogonal directions in a front view of the lamp. The reflecting surface of the reflector is divided into a plurality of segments, and first and second reflective elements, which reflect the parallel light fluxes from the respective lens groups, are provided in each of the segments. With this structure, a portion of all reflective elements can be seen brightly when viewing the lamp from a position directly in front of the lamp and within certain angular limits.
