Description
Technical field
The invention 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 has very excellent colour gamut table because emission spectra is extremely narrow
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 matches,
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
The technical problems to be solved by the invention are based on providing a kind of green transparent ceramics, by blue laser and
Red laser excites green glow ceramics to emit white light, and realizes that the light source of high stability matches and reduced the height of the system cost of light source with this
Colour gamut laser white light source and preparation method thereof.
The present invention is realized using following technical proposals：
A kind of preparation method of high colour gamut laser white light source, it is characterised in that：
Step 1, on a heat abstractor, one or more 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 are fixed on to 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 to obtain high colour gamut laser white light source.
Further, stimulation effect is changed in order to strengthen the light of green glow ceramics, the green glow ceramics are planes or made
Radian or taper with angle, its visible light transmissivity is 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 high colour gamut laser white light source, it is characterised in that：Including heat abstractor, green
Light ceramic, is at least fixed with one or more blue light LD and feux rouges LD on the heat abstractor, or packaged blue light and
Red-light source, green glow ceramics are fixed on the top of described heat abstractor, after powered up blue light LD and feux rouges LD or packaged
Blue light and the light that is sent of red-light source shine directly into green glow ceramic surface, excite to obtain high colour gamut by green glow ceramics and swash
Light white light source.
Further, stimulation effect is changed in order to strengthen the light of green glow ceramics, the green glow ceramics are planes or made
Radian or taper with angle, its visible light transmissivity is 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 present invention has advantages below：
1st, with the prior art realized using RGB modes, RGB is because the light intensity of each color is different, very
It is difficult to match, directly excites green glow to make pottery using blue light LD and feux rouges LD or packaged blue light and red-light source in the present invention
Porcelain, 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；And present invention employs resistant to elevated temperatures green glow ceramics, it will not be produced under conditions of high temperature
Failure, and doping fluorescent material or rare earth material in the preparation, ceramic body are in just yellow or yellow green, not only visible ray
Transmitance is high, through polish and surface coating processing after, light extraction efficiency is higher, it is possible to achieve high transformation efficiency.
