The specific embodiment
Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast accompanying drawing and describe the specific embodiment of the present utility model in detail.
Shown in Fig. 1～3, a preferred embodiment that provides for the utility model, a kind of LED Down lamp, comprise lampshade 1, be arranged on the optical diffusing plate 2 on the lampshade 1 and be arranged on LED illumination module in the lampshade 1, constitute light-source chamber between lampshade 1, optical diffusing plate 2 and the LED illumination module, also comprise the supply unit 4 that is arranged on the outer and radiator 3 of fixedlying connected of light-source chamber and fixedlys connected with radiator 3 and power for the LED illumination module with the LED illumination module.
Preferably, the utility model adopts the supply unit 4 of constant current constant voltage.
Further, radiator 3 is arranged on outside the light-source chamber, fixedlys connected by screw with pcb board 7; Be set with support column 10 on the radiator 3, support column 10 is provided with screwed hole, and radiator 3 is connected and fixed by support column 10 with power pack.
Further, support column 10 is slightly high with the fin 5 of radiator 3, and fin 5 is not directly contacted with power pack, thereby reduces the interference that power pack is subjected to temperature.
