Abstract

The utility model discloses a light emitting diode (LED) lamp heat radiation structure, which is formed on a heat conducting upper cover, wherein the heat conducting upper cover at least comprises two layers which are sheathed at the inner side and the outer side, a gap is formed between the inner layer and the outer layer, vent holes which are penetrated at the inner side and the outer side are respectively formed on the inner layer and the outer layer, and the positions of the vent holes of the inner layer and the outer layer are mutually staggered. When the air circulation heat radiation is ensured by the structure, dust entering the LED lamp is reduced, and in addition, the exposure of internal components is avoided.

Description

A kind of LED lamp radiator structure

Technical field

The utility model relates to a kind of LED lamp radiator structure.

Background technology

In the prior art; The LED lamp mainly is made up of driver circuit plate and translucent cover that heat conduction loam cake, substrate, the electricity of band LED connect substrate and driving substrate; The driver circuit plate is installed in the heat conduction loam cake; Substrate is fixed in the lower port of heat conduction loam cake, and cap surface directly offers the air-vent that runs through inside and outside a plurality of and is used for heat radiation in the heat conduction, and translucent cover covers on the LED.

This structure is by the inside and outside air-vent that runs through, and can accelerate the hot gas outflow really, accelerates to inhale in the cold air, promotes the circulation of heat conduction loam cake inner air and outer air, in time with the heat that produces in the substrate and the driver circuit plate course of work to external diffusion, have better heat radiating effect.

But this structure has following weak point because air-vent exists:

One, air-vent not only helps gas communication, also helps dust and passes in the air-vent entering heat conduction loam cake, but be difficult to dust is blown out from the heat conduction loam cake; So, after use a period of time, will produce laying dust in the heat conduction loam cake; Laying dust covers the driver circuit plate, directly influences radiating effect;

Two, outside from the LED lamp, the air-vent that runs through inside and outside can seeing through is seen in the heat conduction loam cake, makes internals exposures such as driver circuit plate, makes LED lamp external form attractive in appearance inadequately.

In view of this, the inventor improves the radiator structure 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 radiator structure, when guaranteeing the circulation of air heat radiation, reduces dust and gets in the LED lamp, and avoid internals to expose.

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

A kind of LED lamp radiator structure; Be formed in the heat conduction and cover, it is two-layer that the heat conduction loam cake is nested with inside and outside comprising at least, forms the gap between internal layer and the skin; At each air-vent that runs through inside and outside forming on internal layer and the skin, and stagger each other in the air-vent position on internal layer and the skin.

Said air-vent is rounded, oval, long strip type or other shapes.

The internal layer of said heat conduction loam cake is processed with the outer material of commaterial or differing texture that adopts.

After adopting such scheme, the utlity model has following advantage:

One, by the air-vent of inside and outside layer, can promote the circulation of heat conduction loam cake inner air and outer air equally, in time with the heat that produces in the substrate and the driver circuit plate course of work to external diffusion, have better heat radiating effect;

Two, after the air-vent of inside and outside layer staggers each other, only help gas communication, but the structure that staggered hinders, dust is difficult to get in the heat conduction loam cake, has effectively reduced dust and has got in the LED lamp, avoids producing laying dust, and radiating effect is better;

Three, outer field air-vent is stopped by internal layer, makes can't see in the heat conduction loam cake from LED lamp outside, avoids internals to expose, and LED lamp external form is more attractive in appearance.

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

Fig. 2 is the sectional view of the utility model.

Label declaration

Heat conduction loam cake 1 air-vent 11

Gap 12 LED 2

Substrate 3 driver circuit plates 4

Translucent cover 5.

The specific embodiment

Seeing also Fig. 1 to Fig. 2, is a kind of LED lamp radiator structure that the utility model discloses.

The LED lamp is still mainly connect on driver circuit plate 4 and the translucent cover 5 of substrate 3 and driving substrate 3 by substrate 3, the electricity of heat conduction loam cake 1, band LED 2 to be formed.

The improvement of the utility model is: it is two-layer that heat conduction loam cake 1 is nested with inside and outside comprising at least; This paper is that example describes with two-layer, and internal layer can adopt the material of commaterial or differing texture to process with outer as required, and has the effect of better heat radiation; Form gap 12 between internal layer and the skin; At each air-vent 11 that runs through inside and outside forming on internal layer and the skin, and 11 positions of the air-vent on internal layer and the skin stagger each other, and promptly the air-vent 11 on internal layer and the skin does not have to align or overlapping part; Outside from the LED lamp, outer field air-vent 11 is stopped by internal layer.Wherein, air-vent 11 can be circle, ellipse, long strip type or other shapes, is long strip type shown in the figure.

Like this, the utility model can promote the circulation of heat conduction loam cake 1 inner air and outer air equally by the air-vent 11 cooperation internal layers of inside and outside layer and the gap 12 between the skin, has better heat radiating effect; But 11 of the air-vents that inside and outside layer staggers each other help gas communication, but can effectively reduce dust and get in the LED lamp, avoid producing laying dust, and radiating effect is better; In addition, make and to see in the heat conduction loam cake that avoid internals to expose, LED lamp external form is more attractive in appearance from LED lamp outside.

Product form of the foregoing description and graphic and non-limiting the utility model and style, the those of ordinary skill of any affiliated technical field all should be regarded as not breaking away from the patent category of the utility model to its suitable variation or modification of doing.
