Abstract
The present invention incorporates a series of light emitting diodes which transmit an ultra-violet region of the electromagnetic spectrum to a bed of phosphorous to provide a fluorescent light source.
Claims3
A lighting assembly comprising:
- (1) a housing;
- (2) a source of electric power transmitted within the housing;
- (3) a series of light emitting diodes mounted within said housing and sufficient in output wavelength for excitation of phosphorous receptive to an ultra-violet region of the electromagnetic spectrum;
- (4) transforming means to convert power into a known voltage for use by a plurality of said light emitting diodes;
- (5) a light emitting transparent surface having an interior surface area;
- and
- (6) a coating of ultra-violet excitable phosphorous and placed on the interior surface area of said transparent enclosure, whereby when said phosphorous coating is excited by light emitted from said diodes, a light spectrum visible to the naked eye is produced by said coating and through the transparent surface.
