OPTICAL SYSTEM UNIT AND VEHICULAR LAMP

摘要

The present invention enables miniaturization of luminaires while accommodating a plurality of optical system units for different purposes inside a lantern. A projection lens (10) is arranged on the front inside of a first semiconductor light emitting device (6) with a configuration of emitting an incident light from the rear side to the front side. A first reflector (7) reflects some of the light exited from the first semiconductor light emitting device (6) to be focused on the rear side of the projection lens (10). A light guide member (15) is arranged to traverse the front side of the projection lens (10) and exits the incident light from a second semiconductor light emitting device (13) in a pre-set direction. A second reflector (14) reflects some of the light reflected by the first reflector (7) toward the projection lens (10). The incident light reflected by the second reflector (14) and incident on the projection lens (10) is exited from the projection lens (10) avoiding the light guide member (15).
