Description
Technical field
The present invention relates to portable lighting technical fields, more particularly, to a kind of Portable multi-color laser illumination system.
Background technique
In portable lighting, there are flashlight, ceiling lamp, emergency light and desk lamp etc. using more.
And in flashlight application, illuminating source uses LED luminescence chip.Now in entire application end, there is use
Reflector collimates out light, also has and goes out light using collimated, but in the application end of flashlight, few people use the LED of polychrome
Flashlight, and in LED flashlight system, increases multiple colors, when will lead to the output of flashlight total power, caused by light mixing it is uneven
Phenomena such as.
It in LED flashlight, is collimated using reflector, the effect of illumination spot is poor, the practical hot spot of light out
It makes a circle outside, it may appear that halation ring, this phenomenon can not be eliminated directly by reflector.
When using lens to collimate, if the entire flashlight light-emitting angle of demand in this way is small, irradiation distance is remote, light out
Spot effect can show the picture of LED surface, and it is not fine for causing the experience sense of vision.
In the field of LED flashlight, due to the very little of light-emitting window diameter limitation, most flashlight can not all accomplish collimation
By force, CIE colour gamut is wide, excitation purity is high and the preferable product of light mixing effect in polychrome.
And in laser portable lighting, largely use that be all blue laser light source obtain plus wavelength shifter is white
Light, color are single.In portable laser illumination, the strong advantage of collimation in order to play laser completely, laser passes through wavelength
Hot spot very little on converter, energy are very strong, it is easy to burn wavelength shifter, and wavelength shifter is when temperature is higher,
The efficiency of conversion can also reduce.In laser portable lighting, more laser light sources, the temperature tolerance of wavelength shifter are set
It is required that it is higher, and the probability for burning wavelength shifter is also bigger.
Summary of the invention
The present invention is directed to overcome above-mentioned defect in the prior art, a kind of Portable multi-color laser illumination system is provided, no
But light-emitting angle is sufficiently small, can form the multicolour effect of even light mixing, and relative to existing laser portable lighting, will not burn
Ruin the device in lighting system, when the temperature tolerance without considering wavelength shifter is too high with light intensity caused by wavelength shifter burn
Or the consequences such as light efficiency for reducing wavelength shifter.
In order to achieve the above objectives, the technical solution adopted by the present invention is that: a kind of Portable multi-color laser illumination system is provided,
Including laser light source, light path regulating device, light mixing device and receive optical lens；Laser light source includes at least three for being located at more optical axises

The hot spot of laser beam is expanded the light beam for circular light spot to realize first time light mixing, after first time light mixing by piece, diffusion sheet
It is incident to total reflection mirror and is totally reflected mirror and is all-trans again and be incident upon diffusion sheet, diffusion sheet carries out second of light mixing to light beam, through the
Light beam after secondary light mixing is incident on receipts optical lens and is converged out light by it.
Compared with prior art, the invention has the benefit that
It is a variety of by being issued to more lasers since narrow, the monochromatic color excitation purity of the spectrum of laser is high, gamut range is wide
After the laser beam of color carries out optical path adjusting, light mixing is carried out directly on light mixing device, so that light-emitting angle is sufficiently small, it can shape
At the multicolour effect of even light mixing, and relative to existing laser portable lighting, the device in lighting system, nothing will not be burnt
It need to consider that wavelength shifter caused by when the temperature tolerance and too high light intensity of wavelength shifter burns or reduce the light of wavelength shifter
The consequences such as effect.
