Abstract
A lighting device is described for receiving source light within a 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.
Claims24
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;
- a conversion coating applied to the at least one operative surface;
- wherein the at least one operative surface receives the source light, converts the source light into a converted light within a at least one converted wavelength range and redirects the source light towards the desired output direction.
A method of using a lighting device comprising a micro electromechanical system (MEMS) device having at least one operative surface and a conversion coating applied to the at least one operative surface, the method comprising:
- receiving a source light on the at least one operative surface;
- converting the source light received on the at least one operative surface into a converted light within at least one converted wavelength range;
- and
- reflecting the converted light towards a desired output direction.
