  • Patent number: 9719012
    Abstract: A tube lamp has a tubular portion that serves both as a light guide for energy from a solid state source and as a container for a material bearing a nanophosphor that is pumped by the energy from the source as the energy traverses the light guide. However, the tubular portion of the light guide also allows emission of light produced by the phosphor when excited. The material with the nanophosphor dispersed therein may appear either clear or translucent when the lamp is off and the nanophosphor is not excited by energy from the source.
