ABSTRACT:
A white light emitting lamp is disclosed comprising a solid state ultra violet (UV) emitter that emits light in the UV wavelength spectrum. A conversion material is arranged to absorb at least some of the light emitting from the UV emitter and re-emit light at one or more different wavelengths of light. One or more complimentary solid state emitters are included that emit at different wavelengths of light than the UV emitter and the conversion material. The lamp emits a white light combination of light emitted from the complimentary emitters and from the conversion material, with the white light having high efficacy and good color rendering. Other embodiments of white light emitting lamp according to the present invention comprises a solid state laser instead of a UV emitter. A high flux white emitting lamp embodiment according to the invention comprises a large area light emitting diode (LED) that emits light at a first wavelength spectrum and includes a conversion material. A plurality of complimentary solid state emitters surround the large area LED, with each emitter emitting light in a spectrum different from the large area LED and conversion material such that the lamp emits a balanced white light. Scattering particles can be included in each of the embodiments to scatter the light from the emitters, conversion material and complimentary emitters to provide a more uniform emission.
