Light beams mixing device for use in optical system to emit mixed light, has outlet for emitting mixed light, and reflecting surface for deviating light reflected by another reflective surface toward inlet of mixer

摘要

The device (10) has an inlet (7) for receiving light from two light sources (2) i.e. LEDs, and an outlet (6) for emitting mixed light. One of the light sources is provided at an end of collectors, where another end of each collector is connected to the inlet of a mixer (5). The latter end of each collector is equipped with a reflecting surface (31) deviating the light in a direction of a central axis of the mixer. Another reflecting surface (32) deviates the light reflected by the former reflective surface toward the inlet of the mixer.
