Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

As shown in fig. 1-2, the utility model provides a preferred embodiment's a LED lamp, include casing 1 and locate radiator 2, light source subassembly 3, fan 4 and the subassembly 5 that zooms in the casing 1, radiator 2 sets up the one end of casing 1, the subassembly 5 that zoos sets up the other end of casing 1, fan 4 sets up the top of radiator 2, light source subassembly 3 is located radiator 2 with zoom between the subassembly 5, and connect on radiator 2, the bottom of casing 1 corresponds light source subassembly 3 reaches radiator 2 is equipped with air intake 11, the top of casing 1 corresponds fan 4 is equipped with air outlet 12, the center of radiator 2 is equipped with the intake 21 that link up, intake 21 with air intake 11 intercommunication.

Based on the LED lamp with the above technical features, the through air inlet hole 21 is formed in the center of the heat sink 2, and the air inlet hole 21 is communicated with the air inlet 11, so that more air passes through the heat sink 2 (see arrow indication in fig. 2 for a specific air path), and is discharged from the air outlet 12 under the action of the fan 4 to achieve a better heat dissipation effect, thereby ensuring normal use and service life of the lamp. The utility model discloses simple structure, excellent in use effect easily uses widely.

Referring to fig. 3-5, in the present embodiment, the heat sink 2 includes a fin assembly, the air inlet 21 is disposed in the center of the fin assembly, a plurality of copper tubes 22 are uniformly distributed on the periphery of the air inlet 21, and a distance between the uppermost copper tube 22 and the uppermost end of the fin assembly is smaller than a distance between the lowermost copper tube 22 and the lowermost end of the fin assembly. Through with the top copper pipe 22 and the distance of the top of fin subassembly set to be less than the distance of the bottom copper pipe 22 and the fin subassembly of bottom, thereby make the fin subassembly lower extreme can make full use of lamp inner space, and the upper end of fin subassembly is shorter, conveniently is used for the installation fan 4 to the radiating effect has been improved.
