Description
Technical field
The utility model belongs to laser technology field, and in particular to a kind of high colour gamut laser white light source.
Background technology
High colour gamut is to show the direction of pursuit, after it experienced the transitional products such as electricity-saving lamp, LED and transom point, laser
High colour gamut (can reach 150%) receives the consistent accreditation in market, and laser is extremely narrow due to emission spectra, there is very excellent colour gamut table
Present worth, and typically realized at present by the way of RGB, RGB is different due to the light intensity of each color, it is very difficult to match,
Simultaneously as the cost of green laser is too high, the cost for causing light source can be in any more, is unfavorable for large-scale industrialization life
Production.
The content of the invention
Technical problem to be solved in the utility model is to provide based on a kind of green transparent ceramics, is swashed by blue light
Light and red laser excite green glow ceramics to emit white light, and realize that the light source of high stability matches and reduced the system cost of light source with this
High colour gamut laser white light source and preparation method thereof.
The utility model is realized using following technical proposals：
A kind of high colour gamut laser white light source, it is characterised in that：Including heat abstractor, green glow ceramics, in the radiating dress
Put and be at least fixed with one or many blue light LD and feux rouges LD, or packaged blue light and red-light source, green glow ceramics are solid
The top of described heat abstractor is scheduled on, blue light LD and feux rouges LD or packaged blue light and red-light source are sent out after powered up
The light gone out shines directly into green glow ceramic surface, is excited by green glow ceramics and obtains high colour gamut laser white light source.
Further, in order to which the light for strengthening green glow ceramics changes stimulation effect, the green glow ceramics are planes or made
Radian or taper with angle, its visible light transmissivity are not less than 85%, and launch wavelength is between 520-540nm.
Further, stimulation effect is changed in order to strengthen the light of green glow ceramics, green glow ceramics are in blue light and red light irradiation
The plane of incidence is coated with anti-reflection film.
Meanwhile, the invention also discloses a kind of preparation method of high colour gamut laser white light source, it is characterised in that：
Step one, on a heat abstractor, one or many blue light LD and feux rouges LD is at least fixed with, or it is packaged
Blue light and red-light source；
Step 2, green glow ceramics is fixed on the top of described heat abstractor, after powered up, blue light LD and feux rouges LD or
Packaged blue light and red-light source, which lights, shines directly into green glow ceramic surface；
Step 3, blue laser and red laser are excited by green glow ceramics and obtain high colour gamut laser white light source.
Further, in order to which the light for strengthening green glow ceramics changes stimulation effect, the green glow ceramics are planes or made
Radian or taper with angle, its visible light transmissivity are not less than 85%, and launch wavelength is between 520-540nm.
Further, stimulation effect is changed in order to strengthen the light of green glow ceramics, green glow ceramics are in blue light and red light irradiation
The plane of incidence is coated with anti-reflection film.
The utility model has advantages below：
1st, realized with using RGB modes in the prior art, RGB is different due to the light intensity of each color, very
It is difficult to match, green glow is directly excited using blue light LD and feux rouges LD or packaged blue light and red-light source in the utility model
Ceramics, the light intensity parameter of a variety of colors can be good according to Xu's designed in advance, therefore matching is stronger.
2nd, simultaneously, in the prior art because the cost of green laser is too high, the cost for causing light source can be in any more, no
Beneficial to large-scale industrial production；, will not be under conditions of high temperature and the utility model employs resistant to elevated temperatures green glow ceramics
Failure, and doping fluorescent material or rare earth material in the preparation are produced, ceramic body is just in yellow or yellow green, not only may be used
See that light transmission rate is high, after polishing and surface coating processing, light extraction efficiency is higher, it is possible to achieve high transformation efficiency.
