Abstract
The utility model discloses a light-emitting diode (LED) lamp with a high heat dissipation effect, which comprises a substrate for fixing an LED lamp cap, and a uniform-temperature heat dissipation device, wherein the substrate is connected with the uniform-temperature heat dissipation device, and a high radiation heat dissipation coating layer is coated on a heat dissipation surface of the uniform-temperature heat dissipation device. The high radiation heat dissipation coating layer is coated on a heat dissipation surface of the uniform-temperature heat dissipation device, so that the heat dissipation effect of the LED lamp is greatly enhanced, and the heat dissipation requirement of the high-power LED lamp can be met.
Description
Technical field:
The utility model relates to field of illumination lamp technology, especially relates to a kind of LED lamp.
Background technology:
Because the progress of science and technology, lighting apparatus is also higher by brightness, service life is long and LED lamp that power consumption is lower replaces traditions of the past lamp source, and is applied in each different field in large quantities.
Be provided with circuit base plate in the LED lamp, generally speaking, circuit base plate is aluminium base or ceramic substrate normally, but these two kinds of substrates all have the defective in the use to exist.The defective of aluminium base is that thermal conductivity and proof voltage are poor, causing heat radiation to be difficult for, and influences the service life of LED; Though and ceramic substrate has good thermal conductivity, manufacturing cost is higher, quality is frangible.In addition, along with the power of LED lamp is increasing, to the also raising day by day of requirement of heat radiation, traditional LED lamp can't satisfy powerful heat radiation requirement, has big potential safety hazard in the actual use.
In view of this, the applicant develops a kind of LED lamp that can solve high-power heat dissipation problem through the years of researches experience.
The utility model content:
The purpose of this utility model is the weak point that exists at prior art and a kind of LED lamp with high radiating effect is provided that it has the advantages that radiating effect is good, can satisfy high-power heat radiation requirement.
For achieving the above object, LED lamp with high radiating effect of the present utility model includes substrate and the temperature uniforming heat radiation device that is used for fixing the LED lamp holder, substrate links to each other with the temperature uniforming heat radiation device, is coated with high heat loss through radiation dope layer on the radiating surface of described temperature uniforming heat radiation device.
Preferred as technique scheme, described substrate is aluminium base or ceramic substrate.
Preferred as technique scheme, described temperature uniforming heat radiation device is a tabular.
Preferred as technique scheme, described temperature uniforming heat radiation device is the lampshade shape.
Preferred as technique scheme, the thickness of described high heat loss through radiation dope layer is between 1 micron～300 microns.
The beneficial effects of the utility model are: owing to be coated with a floor height heat loss through radiation coating on the radiating surface of temperature uniforming heat radiation device, make the radiating effect of LED lamp greatly promote, can satisfy the heat radiation needs of high-powered LED lamp.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the structural representation of the utility model preferred embodiment;
Fig. 2 is the local enlarged diagram at A place among Fig. 1.
The specific embodiment:
Therefore the following stated only for embodying the preferred embodiment of the utility model principle, does not limit protection domain of the present utility model.
See illustrated in figures 1 and 2: the LED lamp with high radiating effect of the present utility model includes aluminium base (also can be ceramic substrate) 10 that be used for fixing LED lamp holder 20 and the temperature uniforming heat radiation device 30 of lampshade shape (also can be tabular), substrate 10 links to each other with temperature uniforming heat radiation device 30, be coated with high heat loss through radiation dope layer 40 on temperature uniforming heat radiation device 30 and the radiating surface that air contacts, the thickness of this high heat loss through radiation dope layer is best results between 1 micron～300 microns.
