  • Publication number: 20130069519
    Abstract: A multicolored linear light source is disclosed. In an embodiment, the multicolored linear light source comprises a linear light source emanating light of a first spectrum, and regions of photoluminescent material. The light of the first spectrum interacts with regions of photoluminescent material 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. Coupled to each region of photoluminescent material is a columnar light guide such that light produced by the regions traverses respective columnar light guides and gets extracted.
