Detailed description of the invention:

Below in conjunction with accompanying drawing, this utility model is further described, see shown in Fig. 1 ~ 3, LED down of the present utility model, it includes radiator 1, closely be sticked the LED light source plate 2 on radiator 1 front end face, it is fixed on the face ring 3 of radiator 1 front end, shade is at the diffuser 4 in LED light source plate 2 front, diffuser 4 is arranged in the middle part of face ring 3, radiator 1 offers multiple louvre 10 running through radiator 1 front/rear end, this utility model utilizes multiple louvre 10 can considerably increase the area of dissipation of radiator 1, and through louvre 10 can produce stack effect, strengthen cross-ventilation effect, substantially increase radiating effect, and simple in construction, processing is simple, easy to assembly。

The gross area of multiple louvres 10 accounts for the 60% ~ 90% of radiator 1 area of section, it is ensured that the area of dissipation of radiator 1 is sufficiently large, and radiating effect is better。Radiator 1 includes outer portion 11, it is positioned at the internal ring portion 12 within outer portion 11, it is positioned at the heat dissipation base 13 within internal ring portion 12, it is connected by multiple interior fin 15 between internal ring portion 12 with heat dissipation base 13, multiple interior fin 15 are uniformly distributed along heat dissipation base 13 circumference, spatial separation between internal ring portion 12 with heat dissipation base 13 is become multiple louvre 10 by multiple interior fin 15, it is connected by multiple outer fin 16 between outer portion 11 with internal ring portion 12, multiple outer fin 16 are uniformly distributed along internal ring portion 12 circumference, spatial separation between outer portion 11 with internal ring portion 12 is become multiple louvre 10 by multiple outer fin 16, the radiator 1 of this structure has bigger area of dissipation, radiating effect is better。

Offer cable-through hole 14 in the middle part of heat dissipation base 13, facilitate LED light source plate 2 wiring。Face ring 3 circumferentially uniformly offers multiple through hole 31 connected with louvre 10 so that through hole 31 connects formation heat dissipation channel with louvre 10, strengthens cross-ventilation effect, and radiating effect is better。Forming cylindrical portion 32 in the middle part of face ring 3, cylindrical portion 32 rear end extends to LED light source plate 2 place, and diffuser 4 is fixed in cylindrical portion 32, and LED light source plate 2 can be covered by cylindrical portion 32, it is prevented that side light leak, luminous efficiency is better。

Certainly, the above is only better embodiment of the present utility model, therefore all equivalences done according to the structure described in this utility model patent claim, feature and principle change or modify, and are all included in this utility model patent claim。
