  • Photo luminescent light source
    Patent number: 8040028
    Abstract: An apparatus for providing a photoluminescent light source is disclosed. In one embodiment, the apparatus comprises a light source that emanates light of a particular spectrum, photoluminescent material which converts light from the light source to light of another spectrum, and a selective mirror which reflects light generated by the light source and transmits light generated by the photoluminescent material. The photoluminescent material may be arranged so as to provide a plurality of light sources that emanate light of various colors.

  • Multicolored Linear Light Source
    Publication number: 20100283376
    Abstract: A multicolored linear light source is disclosed. In an embodiment the multicolored linear light source (100) comprises a linear light source (100) emanating light of a first spectrum, and regions of photoluminescent material (102,104,106). The light of the first spectrum interacts with regions of photoluminescent material (102,104,106) to give light of a different spectrum. The composition of different regions of photoluminescent material is different, providing light of different spectra in different regions.
