  • Patent number: 6979105
    Abstract: A light fixture having a light reflector, a light source mounted on the reflector, and a photonic filter mounted on the reflector in a position such that light emitting directly from the light source and light from the lamp reflecting from the light source impinges on a surface of the filter, the filter configured to transmit therethrough light of a selected range of wavelengths and to attenuate light of wavelengths outside of the selected range. The light source may be a fluorescent lamp, an incandescent lamp, a HID lamp, or an LED, and may be one of a plurality of light sources. The filter may be formed in a semiconductor substrate and may have an LED light source formed in the same substrate and positioned such that the light produced propagates in a direction away from the filter and toward the reflector, where it is reflected back to the filter.

  • Patent number: 6851834
    Abstract: A light fixture consists of one or more light emitting diode (LED) packaging systems within a housing. Each LED packaging system includes one or more LED light sources that simultaneously shines onto opposing reflecting surfaces, then shines forward through encapsulation material. The housing consists of a cluster of prewired sockets with an outer reflective surface. Electrical wiring runs from the rear of the first socket and then to an adjacent socket in a daisy chain fashion. Each socket includes connectors configured to provide each LED packaging system with a source of electricity. The housing has diffusers that adjust the light to an evenly distributed appearance.

  • Publication number: 20030117798
    Abstract: A light fixture consists of one or more light emitting diode (LED) packaging systems within a housing. Each LED packaging system includes one or more LED light sources that simultaneously shines onto opposing reflecting surfaces, then shines forward through encapsulation material, to present a softer appearance. The housing consists of a cluster of prewired sockets with an outer reflective surface. Electrical wiring runs from the rear of the first socket and then to an adjacent socket in a daisy chain fashion. Each socket includes connectors configured to provide each LED packaging system with a source of electricity. The housing has diffusers that adjust the light to a softer and evenly distributed appearance. The light fixture will operate with reduced energy consumption and little maintenance.
