Embodiment Construction

[0043] Such as figure 1 As shown, it is a light-emitting device that is excited by laser and converted into white light according to the present invention, including a light-converting medium 1 and a laser emitting device 2. The laser light-emitting device emits blue light and is excited and converted into white light after passing through the light-converting medium. . The optical wavelength of the blue laser is between 420-470nm; the blue laser of the above wavelength can be directly generated by the LD chip; it can also be connected by multiple LD chips in series, parallel or series-parallel, and then combined by optical fibers Produced; or produced by a single LD light source or an array at present; it can also be produced by frequency doubling or frequency mixing after gaining through a pump light source; of course, blue lasers with a wavelength of 420-470nm produced by other methods can also be used.

[0044] The light conversion medium can be any one of glass, transpar...

Abstract

The invention belongs to the technical field of illuminating, and particularly relates to a method and a device for converting laser into white light under laser excitation as well as a specific application of the method and the device in the illuminating field. The method for converting laser into white light under laser excitation comprises the following step of exciting a light conversion medium through blue laser and converting the laser into white light, wherein light wavelength of the blue laser ranges from 420 nm to 470 nm, and the blue laser can be directly generated through an LD chip, also can be generated through optical fiber beam combination after a plurality of LD chips are connected in series, in parallel or in a series-parallel hybrid mode, or is generated through an existing single LED light source or array, also can be generated in a mode of frequency doubling or mixing of a pump light source after gaining, or is blue laser with wave length ranging from 420 nm to 470 nm generated by other ways; and the light conversion medium can be any one of glass, transparent ceramic and single crystal.

Description

technical field [0001] The invention belongs to the technical field of lighting, and in particular relates to a method for converting ceramics or crystals into white light by using laser light. 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. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a transparent fluorescent ceramic, which can be converted into white light after being dir...
