Abstract:
1. A lamp for producing visible light, comprising: a solid state source for producing energy in a wavelength range having an upper limit of 460 nm; a container formed of optically transmissive material, coupled to receive electromagnetic energy from the solid state source; a liquid or a gas at least substantially filling an interior volume of the container; one or more doped semiconductor nanophosphors dispersed in the liquid or gas material in the container, the or liquid bearing the doped semiconductor nanophosphor in suspension, each doped semiconductor nanophosphor being of a type excited in response to electromagnetic energy of one or more wavelengths in the range having an upper limit of 460 nm from the solid state source for re-emitting visible light of a spectrum having substantially no overlap with an absorption spectrum of any of the one or more doped semiconductor nanophosphors; circuitry for driving the solid state source to emit the electromagnetic energy into the container to excite the one or more nanophosphors; a housing enclosing at least the circuitry; and a lighting industry standard lamp base mechanically connected to the housing and electrically connected to provide electricity to the circuitry for driving the solid state source.
