Patent attributes
The present invention discloses a laser stimulated white light lighting system, it includes a hemispherical reflector, a light-permeable board, a wavelength conversion layer, a reflective layer and plural heat-radiating structures, wherein the laser light emitted by a laser light source passes through a first light entrance hole of the hemispherical reflector and subsequently through the wavelength conversion layer to produce white light. With the implementation of the present invention, complex production process or equipment is not required thus reduce the system cost, the lighting system is capable of accurately outputting white light and promoting photon recycling effect to raise illumination efficiency. With the addition of a second light entrance hole, wavelength-division or angular division multiplexing can be carried out to raise the intensity of the output white light without increasing the etendue of the source light, thereby widening the range of application of the lighting system.
