Abstract
Various embodiments include a multi-color micro-LED array light source that enables well-overlapped light beams of different colors. The multi-color micro-LED array light source includes a thermally conductive substrate and multiple arrays of different color micro-LEDs integrated on the thermally conductive substrate. The micro-LEDs within each array are electrically connected so that they can all be driven in unison. The multi-color array light source also includes a controller that is electrically coupled to and that drives the arrays of micro-LEDs. The controller drives the micro-LEDs in a manner that produces an output light distribution with a spatial wavelength and angular distribution that is suitable for use as a light source.
