Abstract:
1. A lighting apparatus, comprising: a first source of light of a first wavelength; a second source of light of a second wavelength, the second wavelength being different from the first wavelength; a third source of light, wherein the third source produces substantially white light; an optical cavity having a diffusely reflective interior surface for receiving and combining light of the first and second wavelengths and the substantially white light, from the sources of light, to form white light of a desired spectral characteristic, and having an aperture for allowing emission of the white light of the desired spectral characteristic; and an optical processing element coupled to the aperture of the optical cavity, wherein the optical processing element comprises a deflector having a reflective inner surface coupled to the aperture to deflect at least some of the combined light.
