LIGHTING SYSTEM WITH WAVELENGTH CONVERTING ELEMENT SIDE HOLDING HEAT SINK

摘要

PROBLEM TO BE SOLVED: To provide a technology about wavelength conversion of light generated by a high-brightness light source containing a semiconductor light-emitting device.

SOLUTION: The lighting system includes a light source, such as one or more light-emitting diodes in an array, that produces light having a first wavelength range. A different wavelength converting element is mounted to receive the light emitted by the light source. The wavelength converting element is physically separated from the light source along a beam path. The wavelength converting element converts the light having a first wavelength range into light having a second wavelength range. In one embodiment, a color separation element is directly coupled with the wavelength converting element. The color separation element is also physically separated from the light source. In another embodiment, the wavelength converting element is held by a heat sink by the sides.
