<P>PROBLEM TO BE SOLVED: To provide a lamp unit for a vehicle capable of preventing or reducing generation of a gap (a part darker than the surroundings) among a plurality of illumination areas which are individually controlled for lighting on and off. <P>SOLUTION: In the lamp unit for a vehicle provided with a projection lens arranged on an optical axis extended in a vehicle front-back direction and a light source unit arranged at a further backward side than a back-side focal plane of the projection lens, the light source unit is provided with a plurality of solid light guide lens parts structured in a shape in which an outer peripheral surface between an emission surface and a light-incident surface is narrowed like a nearly conical shape as it is headed from the emission surface arranged at a vehicle front side to the light-incident surface arranged at a vehicle rear side, and a plurality of light-emitting elements emitting light each of which is incident into the light guide lens part from the light incident surface, internally reflected on the outer peripheral surface and emitted from the emission surface. The emission surfaces of the plurality of light guide lens parts are adjoiningly arranged in a nearly horizontal direction in the vicinity of the focal plane of the projection lens, and the plurality of light guide lens parts structure a light guide lens body with the adjoining emission surfaces among each of their emission surfaces coupled with each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
