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.
