Above-mentioned integrated form high-power LED light source is formed the capillary that the cooling matchmaker is flowed by copper is husky in the middle of the wherein said vacuum heat-conduction matrix, and is filled with refrigerant, and is evacuated.Described vacuum heat-conduction matrix has plume vacuum heat-conduction matrix, heat-tube vacuum heat conduction substrate and three kinds of forms of heat-conducting plate.
Above-mentioned integrated form high-power LED light source, wherein said led chip group are mixed with the transparent adhesive tape water layer sealing of fluorescent material.
Major technique effect of the present utility model:
1, adopts the series connection high-power LED chip to form the LED group, reach real constant current.
2, adopt vacuum heat-conduction matrix heat dissipation technology, can improve radiating rate greatly, improve the LED light efficiency, life-saving.
3, adopt square ceramic insulation seat, the shortcoming of can avoid the distortion of conventional plastic frame, becoming flexible, separate, the sealing effectiveness height extends working time.
4, adopt every led chip, very receive pipe for one in parallel, can puncture conducting when single LEDs chip damages, can not influence the work of whole LED group, life-saving.
Below in conjunction with the drawings and specific embodiments technical solutions of the utility model are elaborated.

The specific embodiment
Fig. 1 gets up the led chip series connection, and one in parallel of every LED very receives pipe (5) and forms the LED group, after a led chip damage, can not influence the work that LED organizes by very receiving the pipe conducting like this.Square ceramic insulation seat (2) electrode layer and led chip group are joined
Fig. 2 comprises the square ceramic insulation seat of led chip (1) (2) and vacuum heat-conduction matrix (3) and type free toroidal lens (4).The led chip series connection is got up, one in parallel of every LED very receives pipe (5) and forms the LED group, and square ceramic insulation seat (2) centre is ceramic layer (7), and the upper strata is electrode layer (8), join with the led chip group, lower floor is that copper layer (9) is welded on the vacuum heat-conduction body (3).The led chip group is fixed on the vacuum heat-conduction body that is positioned at square ceramic insulation seat.And the transparent adhesive tape water layer (6) that is mixed with fluorescent material seals.Type free curved surface optical lens (4) is installed in its top.
The vacuum heat-conduction matrix has plume, heat pipe and three kinds of forms of heat-conducting plate, and is shown in Figure 5 as Fig. 3 Fig. 4.
The vacuum heat-conduction matrix is made by metals such as copper, the capillary that the inner cooling coal of being made up of the husky sintering of copper flows, and be filled with refrigerant such as distilled water therein, and be evacuated by liquefaction vaporization circulation side, derive rapidly.The heat that the LED group of high density cluster produces, the temperature that reduces light source extends working time, and reduces the aging and xanthochromia of fluorescent material fluid sealant.The vacuum heat-conduction matrix is divided into plume, heat pipe and heat-conducting plate form, links to each other with external heat sink, can derive heat rapidly.Square ceramic insulation seat is that pottery is made, and has effectively avoided the temperature distortion of traditional square plastic insulation seat, causes loosening, the appearance of segregation phenomenon, guarantee the effect of light source water proof and dust proof high-seal, improve service life, the utility model compared with prior art has obvious advantage and beneficial effect.
The above, it only is preferable enforcement example of the present utility model, be not that utility model is done any pro forma restriction, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified to the equivalent embodiment of equivalent variations, but every utility model technical scheme content that do not break away from,, all still belong in the scope of utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did according to technical spirit of the present utility model.
