Description
Technical field
The present invention relates to a kind of direct insertion laser white light source, apply in lighting field.
Background technology
At present, the technology the most advanced that lighting field uses is LED illumination, and LED illumination is compared with conventional incandescent and energy-conservation
Lamp can be with power saving 50-70%；And laser lighting is as the follow-on lighting engineering of LED, compared with LED can also power saving 50-80%, will be into
For LED alternative product.Existing light source luminescent part is more using LED or using the RGB or color chips in laser lighting
The mode of (colour wheel), its backward in technique, complex process, efficiency are low and application is inconvenient.Therefore it is simple, luminous to provide a kind of technique
Efficiency high and stable luminescence, using it is convenient, beneficial to large-scale production direct insertion laser white light source oneself turn into when business urgently.
The content of the invention
In order to overcome existing conventional light source luminous component due to using LED or using the RGB or color in laser lighting
Backward in technique, complex process, efficiency caused by the mode of piece (colour wheel) are low and the shortcomings that application is inconvenient, and the present invention provides a kind of
Direct insertion laser white light source, have technique is simple, luminous efficiency is high, using it is convenient, beneficial to large-scale production the advantages of.
Technical scheme is as follows：
A kind of direct insertion laser white light source, including direct insertion blue laser emitter, light conversion medium and fixed dress
Put；The direct insertion blue laser emitter upper surface is laser emitting end, and lower surface is provided with pin；The smooth conversion medium
The laser emitting end surfaces of direct insertion blue laser emitter are fixed on by fixing device；The direct insertion blue laser hair
The blue laser that injection device is launched changes into white light by being excited after light conversion medium.
Existing light source luminescent part is due to using LED or using the RGB in laser lighting or color chips (colour wheel)
Mode, its backward in technique, complex process, efficiency are low, and are unfavorable for applying and large-scale production.And the direct insertion laser of the application
The blue laser that white light source is launched using light conversion medium by direct insertion blue laser emitter can be by it after exciting
Change into white light.The laser white light source packaging technology and structure are simpler efficient.The laser white light source is made directly simultaneously
The formula of inserting, it can be ensured that the standardization of products, stabilisation and the large-scale production of application end.
The smooth conversion medium is any of fluorescent glass, transparent fluorescent ceramic, fluorescence monocrystalline.
Because the energy of blue laser is higher, if light conversion medium adds the fluorescence made by silica gel using traditional fluorescent material
Piece, it, in the case where receiving blue laser irradiation, understands high temperature caused by stimulated light and color change and failure occurs for a long time,
Shorten the life-span of light source, cause light quality unstable.And if light conversion medium is using fluorescent glass, transparent fluorescent ceramic or glimmering
Any of light monocrystalline, its visible light transmissivity is high and property is stable, the light that efficiently and stably can be sent blue light source
Be converted into it is a kind of can standard application white light, the long lifespan and light extraction steady quality of light source, greatly save cost.
Visible light transmissivity >=80% of the smooth conversion medium.
The smooth conversion medium is polished and coating film treatment being excited fermentation.
The processing causes the light transmittance of light conversion medium to increase.
The outgoing for being shaped as plane, the conical surface, cambered surface, wherein cambered surface and the conical surface in the beam projecting face of the smooth conversion medium
Angle is 1-150 °.
The design of the shape in the light conversion medium beam projecting face so that light conversion medium light-out effect is good, beneficial to raising
Light conversion efficiency.
The wavelength of the blue laser of the direct insertion blue laser emitter transmitting is 420-470nm.
The direct insertion blue laser emitter is the blue laser light source encapsulated by TO forms.
The fixing device is metal frame, and the metal frame, which encloses, is located at light conversion medium and direct insertion blue laser emitter
Around and both fixed positions, and metal frame upper and lower surface is all provided with the beam projecting face that hole is used to expose light conversion medium
With the pin of direct insertion blue laser emitter.
Fixed using metal frame, there is the characteristics of packaging technology and simple in construction, light handy, fixation, durable.
The direct insertion laser white light source also includes being arranged on the convex lens above the beam projecting face of light conversion medium
Mirror.
The setting of the convex lens can play the effect of optically focused, can reduce ejecting white light angle, enhancing beam brightness.
The convex lens are glass material, acrylics PMMA or other kind of glue in addition to acrylics PMMA
Body class material.
Convex lens spotlight effect is more preferable made of the material.
Compared with prior art, the present patent application has advantages below：
1) different from the mode in the prior art using RGB modes or color chips (colour wheel), the present invention realizes single
Directly conversion after blue laser excites, light extraction steady quality, packaging technology and structure are also simpler efficient；
2) the painting phosphor process of conventional white light light source does not ensure that three primary colours white light laser is easy for the life-span of light source
There is color change by the decay of one of which light, cause light quality also not ensure；And present invention employs high temperature resistant
Fluorescent glass, transparent fluorescent ceramic or fluorescence monocrystalline, it will not produce failure under conditions of high temperature, pass through colloid more now
It is more stable for the flourescent sheet being mixed with fluorescent material, it can be ensured that non-discolouring in the case of a high temperature, color does not float, to ensure light extraction
The stabilization of quality, and due to the stable performance of fluorescent glass, fluorescent crystal and transparent fluorescent ceramic, will not by temperature change and
Change, therefore also extend the service life of light source；
3) high-efficient transparent light conversion medium is employed, the body of fluorescent glass, fluorescent crystal and transparent fluorescent ceramic is in Huang
Color or yellow green, not only visible light transmissivity is high, and after polishing and surface coating is handled, light extraction efficiency is higher, realizes height
Phototranstormation efficiency；
4) the laser white light source of the application is made direct insertion, not only improves production efficiency, and may insure to answer
With the standardization of products, stabilisation and large-scale production at end.
