Abstract

A lamp for a vehicle uses a plurality of LED light sources to irradiate light through indirect lighting, so that not only the entire reflecting surface of a reflector looks roughly the same brightness, but also the degree of freedom of the shape of the lamp is increased. In the vehicle lamp, a plurality of LED light sources (28, 48) are arranged back to back in a row to form first and second LED light source groups (22, 24). A plurality of Fresnel lenses (32, 52) that change the light from each LED light source (28, 48) into parallel light are arranged in a row for each LED light source group (22, 24) to converge into parallel light direction to form the first and second lens groups (24, 44). Also provided are first and second reflection mirrors (26, 46) for reflecting parallel light from each lens group (24, 44). In this way, not only the whole reflective surface of the reflector looks roughly the same brightness, but also the end shapes of the first and second reflectors (26, 46) can be relatively freely set.

Description

technical field [0001] The invention relates to a vehicle lamp with a plurality of LED light sources, in particular to a vehicle lamp for light irradiation through indirect illumination. Background technique [0002] In recent years, automotive lamps with LED light sources have been widely used. At that time, as described in Japanese Unexamined Patent Publication No. 11-306810, by disposing an LED light source that cannot be seen from the front of the lamp, it was a method of making people feel that the lamp is softly emitting light with an indirect lighting effect. Furthermore, as described in German Patent Application Publication No. 19638081, this indirect lighting type vehicle lamp has an LED light source and a Fresnel lens. [0003] The vehicle lamp structure described in the German patent application publication is that a plurality of downward LED light sources are arranged on the upper end of the lamp, and a plurality of upward LED light sources are arranged on the l...
