HIGH INTENSITY WHITE LIGHT SOURCE

摘要

A white light source (100) comprising a first light source (102) adapted to emit first light, a reflecting wavelength converting element (108) arranged to receive first light from the first light source (102) and at least partly convert it to converted light, and a second light source (104) adapted to emit blue light which in use combines with the converted light to generate white light. The white light source further comprises a beam shaping element (116) adapted to adjust the intensity profile of the blue light emitted by the second light source (104) to match the intensity profile of the converted light. Thereby, a white light source (104) which generates a high intensity uniform white light with a desired color distribution is provided.
