Patent ID: 7144131

Claim:
A lighting system, for emitting visible light so as to be humanly perceptible, the lighting system comprising: an energy source package, for emitting radiant energy of a first wavelength; a reflector outside the energy source package, having a reflective surface arranged to receive radiant energy from the energy source package, wherein the reflective surface exhibits a diffuse reflectivity and forms an optical integrating cavity with an aperture for emission of combined radiant energy; at least one phosphor doped within the reflector, such that radiant energy of the first wavelength from the energy source package excites the at least one phosphor to emit visible light, comprising visible light energy of at least one second wavelength different from the first wavelength, wherein at least some of visible light emitted by the at least one phosphor is reflected by the reflective surface of the reflector; and a deflector having an inner reflective surface coupled to the aperture of the optical integrating cavity, wherein the lighting system directs at least the visible light emitted by the at least one phosphor so that it can be perceived by a person.
