Abstract

The utility model discloses an LED (light emitting diode) lamp with a radiating coating. According to the LED lamp with the radiating coating, a heat-conducting coating is arranged at the outer side of the surface, which is in contact with air, of an aluminum radiator of the LED lamp. According to the LED lamp disclosed by the utility model, a layer of heat-conducting material is sprayed on the surface, which is in contact with the air, of the aluminum radiator, so that naturally formed oxide films are prevented, therefore the radiation of the LED lamp is further improved; and meanwhile, the sprayed coating has two colors, namely white and black, so that the situation that the traditional LED lamp is always in a monotonous color, namely aluminum-slivery, is also changed, therefore the lamp becomes more beautiful.

Description

A kind of LED light fixture with heat radiation coating

Technical field

The utility model relates to a kind of LED light fixture, refers in particular to a kind of LED light fixture with heat radiation coating.

Background technology

Since LED light fixture utility model; Its heat radiation is a global technical task always, and the light fixture of main flow heat radiation now all adopts metallic aluminium to dispel the heat, because except noble metal; Copper and aluminium are the best materials of heat radiation; Though and copper is better than the heat radiation of aluminium, because it is much more expensive than aluminium, so finally still adopted the heat sink material of aluminium as the LED light fixture.

Yet aluminium also has a characteristic that is prone to oxidation at normal temperatures, and this layer oxide layer has an effect of protection on the surface of aluminium to aluminium, but for heat conduction, has also formed the non-conductor of one deck heat, thereby reduced heat dispersion.

Summary of the invention

In order to overcome above-mentioned prior art problems, the utility model provides a kind of LED light fixture with heat radiation coating.

In order to achieve the above object, the outer side surface that contacts with air of a kind of aluminium radiator of LED light fixture with heat radiation coating of providing of the utility model is provided with heat conducting coating.

According to the utility model provide LED light fixture one optimal technical scheme with heat radiation coating be: the Heat Conduction Material that said heat conducting coating adopts is a nanostructured zinc oxide.

Beneficial effect: the utility model is at surface spraying one deck Heat Conduction Material that the aluminium radiator of LED light fixture contacts with air; Thereby avoided the oxide-film of natural formation; Therefore further improved the heat radiation of LED light fixture, simultaneously, all right adularescent of the coating of this spraying and two kinds of colors of black; The situation that also to have changed traditional LED light fixture all be this a kind of dull color of aluminium silver color makes light fixture more attractive in appearance.

Description of drawings

The coating structure sketch map of the LED light fixture with heat radiation coating of Fig. 1 the utility model specific embodiment.

The specific embodiment

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

With reference to Fig. 1, in the present embodiment, the outer side surface that said aluminium radiator 1 with LED light fixture of heat radiation coating contacts with air is provided with heat conducting coating 2; The Heat Conduction Material that said heat conducting coating 2 adopts is a nanostructured zinc oxide.

Technological process: the aluminium shell of light fixture (aluminium radiator 1) is gone up spraying one deck Heat Conduction Material; For strengthening the adhesive strength of coating, need do blasting treatment to the aluminum hull surface earlier, after the processing; Spray Heat Conduction Material with spray gun, in high temperature oven, do 8 hours baking and curing at last.

Above content is the further explain that combines optimal technical scheme that the utility model is done, and can not assert that the practical implementation of utility model only limits to these explanations.Under the utility model, the those of ordinary skill of technical field, under the prerequisite of the design that does not break away from the utility model, can also make simple deduction and replacement, all should be regarded as the protection domain of the utility model.

Claims

1. the LED light fixture with heat radiation coating is characterized in that, the outer side surface that said aluminium radiator (1) with LED light fixture of heat radiation coating contacts with air is provided with heat conducting coating (2).

2. the LED light fixture with heat radiation coating according to claim 1 is characterized in that the Heat Conduction Material that said heat conducting coating (2) adopts is a nanostructured zinc oxide.
