White light laser light source packaging method

Abstract

The invention belongs to the technical field of lighting, and particularly relates to a white light laser light source packaging method. The white light laser light source packaging method comprises the following steps that (1) a laser chip is welded to a ceramic support in an inversion or eutectic manner, or the chip is pasted to the ceramic support through glue in a positive mounting manner; (2)the ceramic support is covered with a light conversion medium for converting laser light into white light; and (3) the laser light transmitted by the laser chip and passing through blue light is triggered by the light conversion medium to be converted into white light, wherein the light conversion medium can be any one of transparent fluorescent glass, transparent fluorescent ceramic and fluorescent crystal. A real white light laser light source can be provided, and the extremely-high economic value is achieved.

Description

technical field [0001] The invention belongs to the technical field of illumination, and in particular relates to a light source emitting white light based on a laser chip. Background technique [0002] At present, the most advanced technology used in the field of lighting is LED lighting. Compared with traditional incandescent lamps and energy-saving lamps, LED lighting can save 50-70% of electricity; and laser lighting, as the next-generation lighting technology of LED, can save 50-50% of electricity compared with LED. 80%, will become the replacement product of LED. As for laser lighting, currently some manufacturers have only explored projection and car lights, and usually use RGB or color chips, which are complicated in process and low in efficiency. With the development of laser technology, white light-emitting light sources based on laser chips will be used in large quantities. However, the current technology can only produce laser light sources packaged into blue, g...

Problems solved by technology

As for laser lighting, some manufacturers have only explored projection and car lights at present, and usually use RGB or color chips. The process is complicated and the efficiency is low.

With the development of laser technology, white light sources based on laser chips will be used in large quantities. However, the current technology can only produce laser light sources packaged into blue, green or red light, and there is no real laser white light source.
