Abstract
Official abstract text for this publication.
A lighting device according to another embodiment of the invention for directing source light within a source wavelength range in a blue wavelength range in a desired output direction may comprise a MEMS device that may include a DMD that includes an array of MEMS cells, each MEMS cell including an operative surface to receive and redirect the source light towards the desired output direction. The array of MEMS cells may include first and second pluralities of MEMS cells including first and second conversion coatings applied to the operative surfaces thereof configured to convert source light into first and second wavelength ranges. Furthermore, the repositionable surface of each MEMS cell may be positionable between multiple angles to reflect the converted light. The lighting device may comprise a third plurality of MEMS cells where the operative surfaces thereof is devoid of a conversion coating, or, alternatively, comprises a third conversion coating.
