Abstract
A lighting device is described for receiving source light within a predetermined source wavelength range, converting the source light into a converted light, and reflecting the converted light to a desired output direction. The lighting device may use a micro electromechanical system (MEMS) device to receive and redirect the source light to the desired output direction. A conversion coating may be applied to the operative surface of the MEMS device to convert the source light into a converted light.
