Abstract

The utility model provides a light-emitting diode (LED) light radiator. The LED light radiator comprises an LED light source module, a heat conducting plate and a heat dissipation body, wherein the heat conducting plate and the heat dissipation body are fixedly mounted below the light source module. An air inlet is arranged in the center of the heat dissipation body, multiple vortex airways are distributed in spiral divergence mode on the periphery of the air inlet, and the multiple vortex airways begin with the central air inlet and end with air outlets in the lateral wall of the heat dissipation body. The width of each airway is gradually increased from the beginning to the end, and the heat conducting plate is fixedly mounted on the lateral side of the heat dissipation body with the vortex airways. The LED light radiator is beneficial to the formation of air flow, cool air enters from the center of the heat dissipation body, and heat dissipation of the center is facilitated. Compared with the prior art, under the condition of the same heat dissipation efficiency, the size of the LED light radiator can be greatly reduced, the structure of an LED light is enabled to be more compact, smaller and more exquisite, few materials are used, heat dissipation effect is good, and the LED light radiator can be widely used in LED lights of various power.

Description

A kind of LED lamp radiator

Technical field

The utility model relates to a kind of LED lamp, especially a kind of radiator of LED lamp.

Background technology

Along with the development of new light sources technology, led light source is low in energy consumption because of it, the extremely market favor of the characteristic of long service life, is applied in lighting field more and more widely.Though led light source has the incomparable advantage of conventional light source, the thing followed is light source heating and a heat dissipation problem in use; The heating of LED can cause the decay of led light source, brightness deterioration, damage lamp body when serious; Reduce its service life greatly; And,, badly influenced promotion and application because heating problem is outstanding for the high-power LED light source.

On the other hand, in order to improve the heat dispersion of led light source, prior art is normally quickened to dispel the heat through the surface area that increases fin quantity or increasing radiator; Belong to a kind of passive heat radiation; And the radiator volume is big, causes the lamp body of whole LED lamp also bigger, simultaneously; Radiator edge heat distributes fast and the middle part still is difficult for heat radiation, can produce heat and concentrate and cause led light source group temperature to raise.

Summary of the invention

In order to overcome the deficiency of prior art, the utility model provides a kind of volume LED lamp little, good heat dissipation effect radiator.

The utility model solves the technical scheme that its technical problem adopted:

A kind of LED lamp radiator; Comprise the led light source group, be fixedly mounted on the heat-conducting plate and the radiator of light sources below; It is characterized in that: said radiator center is provided with air admission hole, is dispersed twist to periphery by air admission hole to be distributed with a plurality of swirl air passages, and said a plurality of swirl air passages start from the center air admission hole; Terminate in the gas outlet of radiator sidewall, and the width of air flue becomes big from initiating terminal to clearing end gradually; Said heat-conducting plate is fixedly mounted on the side that radiator has swirl air passage.

The beneficial effect of the utility model is: because radiator dispersed twist to periphery by the center air admission hole and be distributed with a plurality of swirl air passages, and the width of air flue becomes greatly to clearing end from initiating terminal gradually, when led light source group temperature acquires a certain degree; Produce pressure reduction in the swirl air passage,, make that the air-flow trend is moving from middle mind-set peripheral flow because more greatly then pressure is more little away from center width more in the air flue; Constantly air admission hole flows into Cryogenic air from the center, discharges from the air flue gas outlet, takes away heat; Simultaneously, because air flue is designed to spiral helicine swirl air passage, the gas that the gas outlet went out can produce eddy current; Thereby create the negative pressuren zone in exit; Effectively with the gas sucking-off in the runner, thereby improve the radiating rate of radiator, formed active heat removal; And spiral helicine air flue is long than linearity, and heat-conducting area is bigger, and the gas differential pressure in the runner is also bigger, more helps flowing rapidly of air.The radiator of the utility model. help the formation of air-flow, and cold air gets into from the center; More help distributing of center heat, compared to prior art, reach same radiating efficiency; Volume can dwindle greatly, and the structure that makes whole lamp is compact more, and materials are few; Good heat dissipation effect can be adaptable across the LED lamp of various power.

Description of drawings

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

Fig. 1 is the overall diagram of the utility model;

Fig. 2 is the fractionation structural representation of Fig. 1.

The specific embodiment

With reference to Fig. 1, Fig. 2; A kind of LED lamp radiator comprises led light source group 1, is fixedly mounted on the heat-conducting plate 2 and the radiator 3 of light sources 1 below, and said radiator 3 centers are provided with air admission hole 31; Disperse twist to periphery by air admission hole 31 and to be distributed with a plurality of swirl air passages 32; Said a plurality of swirl air passage 32 starts from center air admission hole 31, terminates in the gas outlet 33 of radiator sidewall, and the width of air flue becomes big from initiating terminal to clearing end gradually; Said heat-conducting plate 2 is fixedly mounted on the side that radiator 3 has swirl air passage 32.

Because radiator 3 is dispersed twist to periphery by center air admission hole 31 and is distributed with a plurality of swirl air passages 32, and the width of air flue becomes greatly to clearing end from initiating terminal gradually, when led light source group temperature acquires a certain degree; Produce pressure reduction in the swirl air passage 32,, make that the air-flow trend is moving from middle mind-set peripheral flow because more greatly then pressure is more little away from center width more in the air flue; Constantly air admission hole 31 flows into Cryogenic air from the center, and 33 discharge from the air flue gas outlet, take away heat; Simultaneously, because air flue is designed to spiral helicine swirl air passage, the gas that gas outlet 33 is gone out can produce eddy current; Thereby create the negative pressuren zone in exit; Effectively with the gas sucking-off in the runner, thereby improve the radiating rate of radiator, formed active heat removal; And spiral helicine air flue is long than linearity, and heat-conducting area is bigger, and the gas differential pressure in the runner is also bigger, more helps flowing rapidly of air.

As the preferred implementation of the utility model, the preferred 1.5mm ~ 3mm of the thickness of heat-conducting plate 2, the heat-conducting plate thin thickness can make heat conduction faster of led light source group.

The radiator of the utility model help the formation of air-flow, and cold air gets into from the center; More help distributing of center heat, compared to prior art, reach same radiating efficiency; Volume can dwindle greatly, and the structure that makes whole lamp is compact more, and materials are few; Good heat dissipation effect can be adaptable across the LED lamp of various power.
