Description

LED lamp with heat sinking function

Technical field

The utility model relates to a kind of LED lamp, and is special relevant with its heat sinking function structure.

Background technology

In the prior art; The structure of LED lamp is as shown in Figure 1; Mainly be made up of lamp holder 10, case 20, drive circuit 30 and led light source 40, case 20 covers on the lamp holder 10, and drive circuit 30 is installed in the lamp holder 10; Led light source 40 is installed in the inboard of lamp holder 10 and is in the case 20, and led light source 40 is connected with drive circuit 30.During use, after the energising, luminous by drive circuit 30 control led light sources 40, light sees through case 20, reaches the illumination effect.

It is not difficult to find after careful observation that this LED lamp is that the plane is provided with because of led light source 40, and has only a LED to form spot light usually, its luminous intensity distribution angle has only 60～90 degree, and the effective rate of utilization of light is low, and energy loss is big.

The inventor researchs and develops out a kind of facade light-source structure of LED lamp, as shown in Figures 2 and 3 to the problems referred to above; Comprise facade lamp bracket 50 and some LED lamp plates 60; How much stage bodies of facade lamp bracket 50 for arching upward, the surface of these how much stage bodies forms mount pad, fixed L ED lamp plate 60 on the mount pad.This facade light source is the same with existing led light source to be mounted on the lamp holder 10 and to be in the case 20, and is connected with drive circuit 30.After this structure will have led light source now and be converted into the facade light source by planar light source, the three-dimensional light distribution of whole light source was 300 degree by expanding maximum to below the 120 original degree, and the effective rate of utilization of light is greatly enhanced, and energy loss significantly reduces.

But; So many LED lamp plate 60 shown in Figure 3 adds the heat that the drive circuit 30 that is electrically connected with these LED lamp plates 60 produces in the course of the work; The heat that the drive circuit 30 that is far longer than existing planar LED light source 40 shown in Figure 1 and is electrically connected with it produces in the course of the work; A large amount of heats can't directly influence the service life of LED lamp in time to external diffusion.

As a result, the inventor improves the heat abstractor of LED lamp specially, and this case produces thus.

The utility model content

The purpose of the utility model is to provide a kind of LED lamp with heat sinking function, so that heat radiation in time, avoids temperature too high and influence service life of LED lamp.

To achieve these goals, the solution of the utility model is:

LED lamp with heat sinking function comprises lamp holder, case, drive circuit, facade lamp bracket and led light source, and the facade lamp bracket is how much stage bodies that arch upward; The surface of how much stage bodies forms mount pad, fixed L ED light source on the mount pad, and led light source is connected with drive circuit; Drive circuit is installed in the lamp holder, and the below of facade lamp bracket forms radiating part, has some fins on the radiating part; Be Openworks shape between the fin; The bottom of radiating part is fixed on the lamp holder, and case covers on the top of radiating part, and facade lamp bracket and led light source are in the case.

The edge, front and back of adjacent fin is stacked in the said radiating part.

In the said radiating part, form perforation at least one fin, led light source interts in perforation with the electric wire that is connected between the drive circuit.

Said lamp holder is formed by lamp head shell and the engaging of resin loam cake, and drive circuit is installed between lamp head shell and the resin loam cake.

Buckle one adapter sleeve on said facade lamp bracket and the led light source, led light source is fixed on the mount pad of facade lamp bracket by adapter sleeve.

After adopting such scheme; The utility model can promote the circulation of air that the LED lamp is inner with extraneous through the fin engraved structure of radiating part; The heat that in time led light source and drive circuit is produced in the course of the work has better heat radiating effect to external diffusion, effectively avoids temperature too high and influence service life of LED lamp; Simultaneously, the fin engraved structure of radiating part also makes LED lamp external form more attractive in appearance.

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
