The content of the invention

Technical problem to be solved in the utility model is to provide one kind directly to receive indigo plant using solid-state light conversion medium Ray laser can change into white light after exciting, and for a long time receiving in the case that laser irradiates, will not Stimulated Light produce High temperature and laser that color change and failure occur changes into the light-emitting device of white light, and the light-emitting device is in lighting field Concrete application.

The utility model is realized using following technical proposals：

A kind of Stimulated Light based on glass excites the light-emitting device for changing into white light, including laser beam emitting device and solid-state Light conversion medium, the laser light emitting device is sent blue laser and is excited after light conversion medium and changes into white light, enters one Step ground, the smooth conversion medium is glass；

Further, between a length of 420-470nm of the light wave of the blue laser；

Further, the blue laser of above-mentioned wavelength can directly be produced by LD chips；

Also after connecting after being mixed by series, parallel or connection in series-parallel by many LD chips, then produced after optical-fiber bundling；

Or produced by current single LD light source or array；

Also can be by frequency multiplication or the mixing generation after gain by pump light source；

Or the wavelength of other modes generation is the blue laser of 420-470nm.

Further, the visible light transmissivity of the smooth conversion medium is more than more than 80%；

In yellow or yellow green, its launch wavelength is 520-760nm to the body of the smooth conversion medium.

Further, in order to improve light conversion effect, the smooth conversion medium is polished and coating film treatment being excited fermentation.

The beam projecting face of the smooth conversion medium is shaped as plane, the conical surface, cambered surface, the wherein outgoing of cambered surface and the conical surface Angle is 1-150 degree angle；Or the smooth conversion medium is the lens with light-out effect.

Above-mentioned Stimulated Light excites the light-emitting device for changing into white light, can be applied in following fields：

A kind of white light source, including described Stimulated Light excites the light-emitting device for changing into white light.

A kind of lighting, including described Stimulated Light excites the light-emitting device for changing into white light as light source.

A kind of projection arrangement, including described Stimulated Light excites the light-emitting device for changing into white light as light source.

The utility model has advantages below：

1 is different from the mode that RGB modes or color chips are used in prior art, and the utility model realizes single indigo plant Directly convert after color laser excitation, go out light quality and stablize, packaging technology and structure are also simpler efficient；

The technique of the 2nd, traditional painting fluorescent material does not ensure that three primary colours white light laser is easily by wherein for the life-span of light source A kind of decay of light and there is color change, cause light quality also not ensure；And the utility model employ it is resistant to elevated temperatures Glass, crystal and ceramics, will not produce failure under conditions of high temperature, more now by colloid and fluorescent material be mixed with it is glimmering Mating plate is more stable, it can be ensured that nondiscolouring in the case of a high temperature, not color drift, due to the stable performance of glass, crystal and ceramics, will not Changed by the change of temperature, therefore also not there is a problem of service life,

3rd, employ high-efficient transparent light conversion medium, its body after the completion of preparation just in yellow or yellow green, not only Visible light transmissivity is high, and Jing after polishing and surface coating are processed, light extraction efficiency is higher, and realizes high phototranstormation efficiency.
