Abstract
A device and method for an ultraviolet light (UV) light based visible light generator is disclosed. The UV light source emits a beam of UV light that may be scattered or reflected onto surfaces including UV light reactive materials that produces visible light when exposed to UV light. The UV light may be coherent or non-coherent light. The UV light reactive material may include quantum dot material.
Claims8
A method for producing visible light from ultraviolet (UV) light in a commercial lighting fixture, the method comprising:
- (i) emitting a beam of UV light from a UV emitting light emitting diode (LED) into a planar type visible light apparatus,
- said apparatus having a plastic body (415) and an interior portion,
- said interior portion configured as multiple inner surfaces selected from a first surface (403), a second surface (403a), a third surface (403b), and a fourth surface (425), said inner surfaces each comprising a UV light mirror,
- said interior portion having a UV light reactive surface (420) comprising a UV light reactive composition,
- said apparatus having a horizontal axis and said UV emitting LED configured at a first angle wherein the beam of UV light incident on said inner surfaces and on said UV light reactive surface produce visible light in substantially one direction perpendicular to the horizontal axis;
- wherein the apparatus is mounted in a commercial lighting fixture selected from the group consisting of a ceiling light, a lamp, and a decorative light;
- (ii) causing scattered UV light incident on the UV light reactive composition to emit visible light from said apparatus in a direction substantially perpendicular to the horizontal axis.
