Abstract
A color mixing illumination device and method of using the same. The color mixing illumination device includes a printed circuit board (PCB) having a PCB surface with a reflective portion; a multi-color light source attached to the PCB, such as a red-green-blue light emitting diode (RGB LED); and a reflector with a reflector surface. The PCB surface and the reflector surface are configured to mix light from the multi-color light source in a mixing region and then direct mixed light out of the device from an exit region. In one embodiment, the color mixing illumination device is a multi-color indicator lamp for a vehicle.
