Integrated multi-colored LED light source with heatsink and collimator

摘要

A LED light source is integrated with a heatsink and a collimator. Four isolated heatsinks form an optical taper in which a single color LED is mounted. The LEDs are arranged to form a reflective light recycling cavity. Up to four different colors can be combined inside the light recycling cavity to form a uniform and homogenous mixing of the colors at the exit aperture of the light recycling cavity and/or the exit aperture of the collimator/heatsink.
