Embodiment
As shown in figure 1, be the structural representation of the flashlight of the present invention with new pattern laser light source, the torch
Cylinder includes flashlight cylinder 10, switch part 20, Battery 30, power supply part 40, light source part 50 and lens part 60, opens
Close part 20 to be connected and fix with cylinder 10 by way of rotation, switch part 20 connects the negative or positive electrode of battery 30, electricity
Another pole in pond 30 is connected with power supply 40, and the line drawn from the end of power supply 40 is connected power supply, such as Fig. 2 with light source 50, wherein, the light
Source part 20 is that a kind of stimulated light excites the light-emitting device for changing into white light, including light conversion medium 1 and laser beam emitting device 2,
The laser light emitting device sends blue laser and changes into white light by being excited after light conversion medium.The light of the blue laser
Wavelength is between 420-470nm；The blue laser of above-mentioned wavelength can directly be produced by LD chips；Also can be led to by more LD chips
Cross series, parallel or connection in series-parallel it is mixed after connect after, then produced after closing speed by optical fiber；Or produced by current single LD light source or array
It is raw；Wavelength can certainly be used as caused by other modes as 420-470nm blue laser.
The smooth conversion medium can be any of glass, crystalline ceramics, monocrystalline；Light described in the present embodiment
For conversion medium using crystalline ceramics, the body of the crystalline ceramics is in yellow or yellow green, and its launch wavelength is adjusted
For 520-760nm, it is seen that when light transmission rate is more than more than 80%, the phototranstormation efficiency that it is obtained is optimal.In order to improve light conversion
Effect, the smooth conversion medium are polished and coating film treatment being excited fermentation.Meanwhile the beam projecting face of the smooth conversion medium
