Description of drawings

Fig. 1 is the sketch map of the said high-power LED lamp structure of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further detailed description, can implement according to this with reference to the specification literal to make those skilled in the art.

As shown in Figure 1, the described high-power LED lamp structure of the utility model comprises metal base 1 and LED light-emitting component 2, and wherein, said metal base 1 can adopt aluminium or aluminium alloy or other light weight and the metal of perfect heat-dissipating is processed.Offer chamber 3 at the top of said metal base 1, this chamber 3 can punching press, or utilize milling cutter to process.The bottom surface 4 of said chamber 3 is an exiting surface, and the internal face 5 of chamber 3 is a light-emitting area, and said LED light-emitting component 2 is set on the exiting surface; On the opposite face of this LED light-emitting component 2, also protecting glass 9 can be set, this protecting glass 9 is arranged in the top of metal base 1, so that LED light-emitting component 2 is carried out insulation blocking.Because pedestal 1 is to adopt the metal material processing and fabricating to form, therefore, the heat that LED light-emitting component 2 is produced when luminous can directly be absorbed and conduction fast by pedestal 1.In the utility model; For overcoming the problem of LED light-emitting component poor heat radiation in the prior art; Special periphery at metal base 1 coats coolant jacket 6; Then be full of cooling fluid 7 in the cavity space between said coolant jacket 6 and the said metal base 1, said cooling fluid 7 can adopt cooling water or cooling wet goods to possess the liquid medium of refrigerating function.In the described high-power LED lamp structure of the utility model, through coolant jacket being set, and making in the cavity space between coolant jacket and the metal base and be full of cooling fluid in the metal base periphery; Make this cooling fluid capable of using quicken cooling to metal base as the heat conduction media; Also promptly the LED light-emitting component is carried out fast cooling, its cooling effect is superior to natural wind cooling mode of the prior art greatly, therefore; Can significantly reduce the temperature of LED light-emitting component; Improve the service time and the brightness of LED light fixture, and the mode of utilizing cooling fluid to cool off also can reduce the volume of LED light fixture, increase LED light fixture convenience that carries and the convenience of installing and using.

As shown in Figure 2, in the described high-power LED lamp structure of the utility model, also can comprise transparent cover 8, this transparent cover 8 is arranged at the periphery of metal base 1 and coolant jacket 6, so that metal base 1 and coolant jacket 6 are covered with wherein.For example, the LED irradiation headlight that is applied to vehicle front promptly is this class formation, said LED light fixture is installed in vehicle body after, the outer again Transparent lamp shade that covers.
