Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Below in conjunction with specific embodiment, specific implementation of the present utility model is described in detail:
Please refer to Fig. 3 ~ 5, the utility model embodiment provides a kind of LED lamp, comprise heat sink body 1 and lamp holder 2, this heat sink body 1 comprises integrated first radiator 11 and the second radiator 12 two parts, with further reference to Fig. 6,7, the tubular groove 111 that first radiator 11 comprises bottom flat and the annulus 112 extended out from the edge of tubular groove 111, this annulus 112 is provided with several the first through holes 113, and these first through holes 113 are preferably uniformly distributed.The bowl-type of the second radiator 12 in open at both ends, it docks compared with the outer of big open end end with the annulus 112 of the first radiator 11, and less opening end docks with lamp holder 2.Lamp holder 2 comprises shell 21 and LED illuminating module 22, and after assembling, LED illuminating module 22 is positioned at the bottom of tubular groove 111.First radiator 11 both as radiator, again as the supporting body of LED illuminating module 22 and translucent cover, simultaneously as a part for lamp outer casing, as a part for radiator and lamp outer casing the while of the second radiator 12.The shell 21 of lamp holder 2 docks with the second radiator 12, this shell 21 is provided with several second through holes 211, second through hole 211 is preferably uniformly distributed in the identical At The Height on shell 21, the second through hole 211 on first through hole 113 of the first radiator 11 and lamp holder 2 shell 21 is mutually through, forms cross-ventilated passage therebetween.The tubular groove 111 of above-mentioned first radiator 11, annulus 112, first through hole 113 and all one-shot formings in same technique of the second radiator 12, and the metal of the preferred perfect heat-dissipating of the material of heat sink body 1.
