Abstract
The utility model discloses an LED (Light-Emitting Diode) lamp with high-efficient heat dissipation. The LED lamp comprises a lampshade, wherein an aluminum substrate and an LED lamp source on one end surface of the aluminum substrate are arranged in the lampshade. A first copper magnetic heat dissipation fin is arranged on the end surface of the aluminum substrate, and an aluminum second magnetic heat dissipation fin is arranged on the outer surface of the lampshade. An annular heat conduction pipe is arranged on the second magnetic heat dissipation fin and is a pipe body in a sealing state, and anti-freezing cooling liquid is arranged in the pipe body. The first magnetic heat dissipation fin and the second magnetic heat dissipation fin can be respectively increased or decreased according to the actual requirement, and the magnetic heat dissipation fins have the advantages that the magnetic heat dissipation fins can be conveniently and firmly installed and be conveniently disassembled and the like. The LED lamp overcomes the defects of more impurities, serious environmental pollution, low mechanical property, short service life, high falling possibility and the like. The mechanical strength and the purity of the heat dissipation fins are greatly increased, the service life is long, and the heat dissipation fins are not fall off and have a good heat dissipation effect to the LED.
Description
Technical field
The utility model relates to a kind of LED light fixture of high efficiency and heat radiation, relates in particular to a kind of LED light fixture that can rapidly and efficiently dispel the heat.
Background technology
Along with developing rapidly of microelectronics integrated technology and high density PCB package technique, packing density improves rapidly, and thousands of times of ground of the volume of LED element dwindle, and LED instrument and equipment are day by day towards light, thin, short, little future development.Can discharge higher heat when LED is luminous, the working heat environment of LED is mobile rapidly to the high temperature direction; At this moment, the heat run-up, the increase that produce when LED is luminous under the environment for use temperature, make LED still can work on high efficient and reliable ground, and heat-sinking capability becomes the critical limitation in LED light decay and service life thereof the factor that affects timely.Reliability when ensureing that LED is luminous needs to use the material of the excellent combination properties such as high reliability, high thermal conductivity, adds efficient radiator structure.The heat transferred radiator of like this could be rapidly, in time LED being gathered makes LED in time dispel the heat, and ensures that LED's is normally luminous.
Present employed heat sink material substantially all is aluminium alloy, but the thermal conductivity factor of aluminium is not very high (237W/mK), and the heat conductivility of Jin Heyin is higher, but price is too high, and the thermal conductivity factor of copper takes second place (398W/mK), but weight of copper is large, easily oxidation, and price is not low yet.
Summary of the invention
Technical problem to be solved in the utility model is the defective that overcomes prior art, provide a kind of to LED have no adverse effects, non-environmental-pollution, prepared fin machinery intensity is high, long service life, adeciduate LED light fixture.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of LED light fixture of high efficiency and heat radiation, comprise lampshade, be provided with aluminium base, the LED lamp source on aluminium base one end face in the lampshade, the end face of described aluminium base is provided with the first copper magnetic heat radiator, and the outer surface of lampshade is provided with the second magnetic heat radiator of aluminium matter; The second magnetic heat radiator is provided with annular heat pipe.Described annular heat pipe is the body that is in sealing state, is provided with anti-freeze cooling liquid in the body.The first magnetic heat radiator and the second magnetic heat radiator all can be because actual needs increase and decrease to some extent, and the benefit of magnetic heat radiator is conveniently to install, installs firmly and convenient disassembly etc.
Heat pipe is copper pipe, heat pipe has good heat transfer performance, can be delivered to rapidly the other end from the heat of an end, in heat pipe, be loaded with anti-freeze cooling liquid, just realized the hot transfer process an of the best, this transfer process is not only by the metal transferring heat, but utilizes the interior anti-freeze cooling liquid of copper pipe as heat-exchange medium, the heat conductivity of anti-freeze cooling liquid is about 200 times of copper, and cooling fluid has good thermo-responsive.This heat pipe also has stable cooling effect, different from method (using water proof sheet and cooling tube) in the past, heat pipe is seldom because getting rusty and the reason such as incrustation scale makes anti-freeze cooling liquid reduce causing cooling effect to descend, do not worry that anti-freeze cooling liquid can evaporate and leak yet, reduced a large amount of maintenances and maintenance work, the temperature range that heat pipe uses is 50 ℃ to 200 ℃; When heat pipe dispels the heat, can be shaped circulation cooling and shorten heat radiation time more than 30% (at a high speed heat absorption and cooling).The luminous heat that sends in LED lamp source is delivered to rapidly the first magnetic heat radiator from aluminium base, again heat is passed to lampshade, again by the heat radiation of the second magnetic heat radiator, can reach the effect of LED lamp source quick heat radiating and maintenance low temperature.
In sum, LED light fixture of the present utility model is compared with the LED lamp source of use common radiator of the prior art, has overcome that the impurity that exists among traditional preparation technology is many, environmental pollution is large, mechanical property is low, service life is short, and the defective such as easily come off.Non-environmental-pollution in process of production, its mechanical strength and purity improve greatly, and long service life does not come off; Heat radiation to LED has very superior radiating effect.
