ABSTRACT:
A vehicular lamp employing a plurality of LED light sources and arranged to emit light using indirect illumination wherein the total light emittance in the front direction of the lamp is increased by more effectively using the light from the LED light sources. The LED light sources are arranged in a line in the vertical direction such that their direction of light emission is toward the rear of the lamp. The reflecting surface of the reflector is divided into right and left reflecting areas by a boundary line. With this arrangement, a large portion of the light from each LED light source contributes to the light reflected by the reflector. The reflecting areas are divided into a plurality of small reflecting surfaces, preferably two for each LED light source. Thus, it is possible to separately control the reflection of the light from each LED light source by the small reflecting surfaces on both sides of the LED light sources. When the lamp is observed from the front, the number of illuminated areas is greater than the number of LED light sources.
