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.

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, a camera, and a selective mirror placed between the light source and camera. The selective mirror transmits light of a spectrum detected by the camera and reflects light of a spectrum generated by the light source. The light source is transparent to light incident on its face.
