According to technical scheme provided by the invention, in the side of cooling stand led light source is set, it is characterized in that: cooling stand is strip, curved of its end face, several led light sources are positioned at the one or both sides of cooling stand.
Lower side at cooling stand has bottom face, adheres to phosphor powder layer on bottom face.The bottom face that is attached with fluorescent material is coarse surface.
Lower side at cooling stand has bottom face, and some micro-grooves are set on bottom face.Bottom face is parallel with the pin of led light source.
Article one, cooling stand forms a group with the two row led light sources that are positioned at its both sides, and a plurality of groups are arranged in juxtaposition, and form an illuminating module.The degree of depth of micro-groove is 7: 1 with the ratio of width.In the bottom of radiator bearer the fold type spacer is set.Described led light source is arranged on the substrate (as pcb board), and the white reflection layer is set on described substrate.
Advantage of the present invention is: employing has the curved face type cooling stand and the led light source of heat radiation, light reflection and light multiplication multi-functional and forms the integrated form plane luminous module, a kind of new way that solves the heat dissipation problem of power modules not only is provided, has also solved the problem of the inhomogeneous generation hot spot of spot light power-type LED module colour mixture.Widened the high light efficiency life cycle of LED illuminating module, improved the light efficiency nearly 20% more than of optical mode group, also improved the ratio of performance to price of optical mode group, for LED high-power illumination light fixture is introduced the high-power type illuminating module of the curved face reflecting type LED that a kind of feasible high light efficiency is provided to the market.

The specific embodiment
In the side of cooling stand 5 led light source 2 is set, cooling stand 5 is strip, curved 1 of its end face, and several led light sources 2 are positioned at the one or both sides of cooling stand 5.Described cooling stand 5 is installed on the underframe 7 to spaced and parallel respectively with led light source 2.
Lower side at cooling stand 5 has bottom face 4, adheres to phosphor powder layer on bottom face 4.The bottom face 4 that is attached with fluorescent material is coarse surfaces.
Lower side at cooling stand 5 has bottom face 4, and some micro-grooves are set on bottom face 4.Bottom face 4 is parallel with the pin 3 of led light source 2.
Article one, cooling stand 5 forms a group with the two row led light sources 2 that are positioned at its both sides, and a plurality of groups are arranged in juxtaposition, and form an illuminating module.The degree of depth of micro-groove is 7: 1 with the ratio of width.In the bottom of radiator bearer 5 fold type spacer 6 is set.Described led light source 2 is arranged on the substrate, and the white reflection layer is set on described substrate.
As shown in Figure 1, the optical mode group matrix of forming by the led light source 2 of 10 groups of 40 Ф 5mm, between each matrix, make cooling stand 5 with thick 2mm curved face type aluminium alloy plate in, also possess following two functions.On the one hand, the emergent light that makes led light source 2 is done the light reflection of led light source 2 optical mode group emergent lights by the curved surface 1 of cooling stand 5.On the other hand, be coated with on the basis of white reflection layer at the PCB that the LED matrix is installed, on the bottom face 4 of cooling stand 5, adhere to layer of fluorescent powder, and this bottom face 4 that has adhered to fluorescent material carried out roughening treatment, the scattered light of led light source 2 makes LED optical mode group do efficiency light output by bottom face 4.
Installing and fixing of curved surface cooling stand 5 is that fold type spacer 6 by cooling stand 5 bottoms is realized.Another effect of spacer 6 is that the heat on the curved surface cooling stand 5 is conducted to heat conduction pad on the PCB substrate of module bottom to make the usefulness of heat radiation conduction by it.
Secondly in order further to strengthen the radiating effect of curved surface cooling stand 5, for more taking away the heat on the LED pin 3, bottom design aspect partly at curved surface cooling stand 5, the present invention has specially designed the bottom face 4 that parallels with LED pin 3, and to have made dark, wide ratio on this bottom face 4 be 7: 1 micro-groove, utilize this micro-groove heat radiation, to strengthen heat radiation and the thermal convection current between curved surface cooling stand 5 and the LED illuminating module pin 3, can take away the heat on the LED pin 3 so more, thereby prolong the high light efficiency life cycle of LED optical mode group.
The present invention integrates the designing technique of having quoted advanced optics, calorifics, structure, material, makes it have features such as heat radiation, light reflection, light multiplication.In invention is made, optical mode group structure whole heat radiation and optical design have been carried out from system perspective.
Optical mode group of the present invention is in when work, not only the surface temperature of the Ф 5mmLED light source 2 of epoxy packages and the temperature of pin 3 distributed by curved face type cooling stand 5, improves and widened the operating temperature characteristic of led light source 2.Moreover the emergent light of LED optical mode group is except that direct ejaculation, and refract light that module is outer and the scattered light of LED back-reflections and LED reflect by the reflective of the reflective matsurface on the curved face type cooling stand 5 or after repeatedly reflecting again and project light.
The technology of the present invention key is two aspects:
One, apposition fluorescence reflectorized material on the reflection of curved surface cooling stand 5 is faced the wall and meditated.Through the fluorescent material of roughening treatment not only its coarse surface uneven the normal direction of incident light is differed and causes light diffusion; But also the light of light firing angle degree outside critical angle also can be closed in the angle by repeatedly refracting to, make module obtain more bright dipping.Secondly, because after the curved face type shape of reflecting surface made scattered light pass through repeatedly to reflect again, the directed shoot mode of making emergent light by curved surface had reduced module outgoing diffusion of light.It does not only injure the electric light feature of LED point luminescent device, but also makes the light emission rate of module improve more than 20%.Moreover, also make the optical uniformity of optical mode group emergent light better.
Optical mode group of the present invention has higher performance, be that it has unique curved face type heat radiation, light reflection and light and doubles in the optical mode prescription formula of one and electric light source efficient efficiently, and good optical uniformity and the tangible price advantage that has, make it have more market value.For the commercial practicality of LED large-power lamp now provides the brand-new group of optical mode efficiently---a curved face reflecting type LED power optical module group.
