Abstract:
1. An emitter, comprising: a light source which emits a first spectrum of light; and a hemispheric conversion material region formed separately from said light source and including conversion particles distributed uniformly throughout said hemispheric conversion material region, said conversion material region mounted to a surface above and spaced apart from said light source and positioned in proximity to said light source such that at least some of said light source light passes through said conversion material region, said conversion material region shaped such that all of said light passing through travels through substantially the same thicknesses of said conversion material region, said conversion particles absorbing at least some of said light source light passing through said conversion material region and emitting a second spectrum of light, wherein said first spectrum of light and said second spectrum of light are combined within said conversion material region, said emitter emitting a combination of said first and second spectrums at a substantially uniform color and intensity.
