Abstract
The utility model relates to a LED lamp self-heat radiation device which comprises a LED, radiation fins, a radiation chamber, an air inlet and an air outlet, wherein, the radiation chamber is communicated with the atmosphere through a conduit or directly communicated with atmosphere, and the air outlet is arranged above the air inlet. The utility model adopts double radiation technology of radiation fins and radiation chamber, on the one hand radiation fins are exposed in atmosphere directly to dissipate heat; on the other hand, air in radiation chamber absorbs heat generated by the LED, because of thermal expansion and cold shrinkage, the heat generated by the LED can be effectively and timely emitted into environmental air through directional flow generated by air in the atmosphere through conduits. The self-heat radiation device has the advantages of heat radiation by air directional flow, good heat radiation effect, simple structure and lower cost, and can effectively solve the problem of heat radiation of the LED lamp. The utility model can be widely applied to various LED lamps.
Description
Technical field
The utility model belongs to a kind of heat abstractor, relates in particular to a kind of LED lamp self-heat irradiation device.
Background technology
From the end of the nineties in last century, white light LEDs has obtained fast development, its be expected to become the 4th generation illumination light source.Different with the luminescence mechanism of traditional lighting light sources such as incandescent lamp, fluorescent lamp, LED belongs to electroluminescent (EL) device, and its heat can not heat loss through radiation, thereby causes device temperature too high.At present, power type white light LED can only be converted into luminous energy with about 20% electric energy, and remaining 80% energy changes into heat energy.Along with the increase of LED power, quantity of heat production increases, and bad if heat dissipation problem solves, heat concentrates in the small-sized chip, makes that the chip internal temperature is more and more higher.The too high meeting of chip temperature brings many problems: (1) quickens device aging, reduction of service life, even also can cause chip to burn; (2) make the wavelength generation red shift of blue-ray LED, and colourity, the colour temperature of white light LEDs produced material impact,, departed from the absworption peak of fluorescent material, will cause the fluorescent material quantum efficiency to reduce, influence light extraction efficiency if wavelength shift is too much; (3) temperature also has a significant impact the radiation characteristic of fluorescent material, along with temperature rises, the fluorescent material quantum efficiency reduces, bright dipping reduces, radiation wavelength also can change, the change of fluorescent material radiation characteristic also can cause the variation of white light LEDs colour temperature, colourity, and higher temperature also can be quickened the aging of fluorescent material.This shows that one of bottleneck of great power LED development is the heat radiation of device.
At present, the LED lamp heat-radiating device generally adopts monolithic construction, adopts the aluminium alloy moulding, be band LED lamp installed surface heat radiation rack on one side, another side is provided with the polylith fin, one or more LED lamps can be fixed on the heat radiation rack, by the fin heat radiation, be installed in the lamp housing.Yet there is high material consumption in the monoblock type heat abstractor, and production cost high the deficiency that bothers is installed, and weight is bigger, is difficult to be applied in these occasions strict to weight such as street lamp, garden lamp, suspension lamp when being combined into light fixture.In addition, install the radiating efficiency that fan also can improve fin additional, but can increase the cost of LED light fixture like this, and cause the waste of the energy, also science not.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes above-mentioned prior art, and a kind of free air guided mobile heat radiation, good heat dissipation effect, simple in structure, lower-cost LED lamp self-heat irradiation device of utilizing is provided.
For achieving the above object, the technical solution adopted in the utility model is: the LED lamp self-heat irradiation device, including LED, fin, LED is connected with fin, this heat abstractor has a heat radiation chamber, there is air inlet in the heat radiation chamber, the heat radiation chamber is communicated with atmosphere by conduit or directly communicates with atmosphere, is formed with the gas outlet above air inlet.
The heat radiation chamber is formed by the fin sealing.
Heat radiation surface, chamber is fixed with heat radiating fin structure.
Heat radiation chamber or conduit are at least one.
Fin directly forms outer shelly, as the shell of light fixture.
Fin is one or more in metal fin, ceramic heat-dissipating sheet, the alloy fin.
Because utility model has adopted the dual heat dissipation technology of fin with the heat radiation chamber, fin is directly exposed in the atmosphere and dispels the heat on the one hand; On the other hand, the heat that absorption of air LED produces in the heat radiation chamber produces directed flow owing to expand with heat and contract with cold by the air in conduit and the atmosphere, can effectively be dispersed into the heat that LED produced in the surrounding air timely.The utility model can effectively solve the heat dissipation problem of LED light fixture, and simple in structure, cost is lower, can be widely used in the various LED light fixtures.
