1. A lighting device for directing source light within a predetermined source wavelength range in a desired output direction, the lighting device comprising:
- a micro electromechanical system (MEMS) device that includes at least one operative surface to receive and redirect the source light towards the desired output direction;
a conversion coating, that includes a phosphorous wavelength coating material, applied to the at least one operative surface to convert the source light into a converted light within a predetermined at least one converted wavelength range;
wherein the MEMS device is a digital micromirror device (DMD) that includes an array of mirrors positionable between multiple angles to reflect the converted light; and
wherein the predetermined source wavelength ranges includes a plurality of wavelength ranges that are selectively enabled.

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.
