Abstract
The invention discloses an LED radiating module. The LED radiating module comprises an aluminum radiating fin bonded with an LED lamp and coated with a nanometer coating layer on the surface, wherein a heat conducting glue layer is arranged between the LED lamp and the aluminum radiating fin; the nanometer coating layer is 0.15-0.2 mm thick; and the heat conducting glue layer is 0.15-0.2 mm thick. The LED radiating module can transfer the heat gathered in the operation of LED to surrounding air with the fastest speed. Compared with a general radiator, under the same power, the volume of the radiator can be decreased, the weight of the radiator can be lightened, and the material can be saved. The most important is that a high-heat-conductivity aluminum alloy substrate and a novel auxiliary radiating material are reasonably combined and applied to achieve the purpose of improving the radiating efficiency.
Description
Technical field
The present invention relates to field of LED illumination, specifically, a kind of LED heat radiation module.
Background technology
LED illumination lamp is the general designation of LED lamp, and along with the further maturation of LED technology, LED will obtain how better development at the room lighting Design of Luminaires development field.The room Design of Luminaires of 21 century will be designed to main flow with LED lamp, fully demonstrates the illumination development trend of energy-saving, health, art up and hommization simultaneously, becomes the leading of room light culture.In new century, LED illumination lamp will illuminate everyone room, changes everyone life, becomes the once great of light fixture development and Design and changes.
LED lamp amasss little light weight, and can select the various modules that different photochromic LED combination becomes illumination soft, be arranged on arbitrarily in room, the light source of the room lighting light fixture may derive from ground, metope, windowsill, furniture, jewelry etc.Therefore, following the room lighting will no longer be confined to single light fixture, and will be converted into the shadowless lamp of the integral illumination effect without ligthing paraphernalia sense by single lamp lighting.Different photochromic and brightness can produce different impacts to the physiology of people with psychology, and people do not need very bright white light under many circumstances, and the light of possible gold-tinted or other color is more suitable for the needs of physiology and psychology.Three-primary color LED can realize brightness, gray scale, the continuous transformation of color and selection, makes to throw light on to expand to the light of multiple color from the white light universal significance.
When the power of LED chip and COB does larger and larger, require also more and more higher to the radiating efficiency of radiator.For adapting to high-power LED illumination application, need the LED heat radiation module designing a kind of superelevation rate of heat dissipation.
Summary of the invention
The object of the invention is to the above problem overcoming prior art existence, a kind of LED heat radiation module is provided.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of LED heat radiation module, comprise and the aluminum radiating fin that LED is fitted, surface spraying has nano coating, be heat conduction glue-line between described LED and described aluminum radiating fin, described nano coating thickness is 0.15-0.2mm, and described heat-conducting glue layer thickness is 0.15-0.2mm.
The invention has the beneficial effects as follows:
1, the heat assembled when LED can work by the present invention conducts to surrounding air with the fastest speed.Compared with common radiator, the volume of radiator can be reduced under Same Efficieney, alleviate heatsink weight, save material.
2, mainly the reasonable combination of high heat conduction aluminum alloy base material and novel auxiliary heat sink material is applied, and improves radiating efficiency object to reach.
3, the heat transfer of LED and aluminum radiating fin is replaced with the heat-conducting glue of ultra-high conducting heating rate (thermal conductivity is 30W/m.K) by traditional heat conduction adhesive tape (thermal conductivity is at 1-3W/m.K) or heat-conducting silicone grease (thermal conductivity is at 1.5-5W/m.K).
4, the contact surface of aluminum radiating fin and air increases nano-spray coating.
5, by above two significant improvement, the radiating efficiency of radiator is greatly improved.Contrast traditional heat-dissipating mode, can make the average temperature rising of light fixture reduce 10-18 DEG C under equal conditions.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present invention.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
