Vehicular signal lamp having a plurality of light-emitting diodes
 A signal lamp for a vehicle is composed of a plurality of LED lamps as a light source, a reflecting surface corresponding to the light-emitting surface of the signal lamp, a housing for accommodating the LED lamps and the reflecting surface, and an outer lens disposed in opposing relation to the reflecting surface. The LED lamps are arranged along the periphery of the light-emitting surface such that the illuminating direction thereof is toward the center of the reflecting surface. The reflecting surface is partitioned into segments corresponding in number to the LED lamps. Preferably, the reflecting surface has a circular configuration. The segments into which the reflecting surface is partitioned are arranged radially around the center of the reflecting surface. In this case, the LED lamps are arranged in an annular configuration along the periphery of the reflecting surface. As the LED lamps, there are used plural pairs of LED lamps, each pair of LED lamps being disposed in opposing relation to each other with the center axis of the reflecting surface interposed therebetween. In this case, the reflecting surface is composed of two types of reflecting portions being alternately arranged, one for reflecting a light beam from one of each pair of opposing LED lamps and the other for reflecting a light beam from the other of each pair of opposing LED lamps. A shade for blocking direct light beams from the LED lamps is provided adjacent the LED lamps.
