Abstract
The utility model provides a heat radiation structure of LED (light emitting diode) lamps. An LED bead and a heat radiator are connected through a fixing column; heat generated by the LED bead is transmitted to the whole heat radiator by the fixing column, thereby improving the heat radiation efficiency. Furthermore the heat radiator composed of a plurality of fins has high heat exchange efficiency with air; and the whole lamp has a good hear radiation effect.
Description
Technical field
The utility model relates to a kind of radiator structure, particularly relates to a kind of LED lamp cooling structure.
Background technology
Along with the LED development of technology, also adopt LED in the lighting more and more at present as light source, but because the demand of lighting environment, the power of LED is done bigger and bigger, and the heat radiation that thereupon produces is also increasingly high, and high temperature has had a strong impact on the service life of LED.Though present high-power LED lamp has also been taked cooling measure, receive the restriction of traditional processing technology thoughtcast, the contact area of substrate and radiator that LED lamp pearl is installed is limited; Heat is difficult to reach entire radiator; Can not make full use of the heat exchange area of radiator, so traditional heat-dissipating mode radiating effect is relatively poor, radiating rate is slow; The heat that accumulates on the LED assembly is difficult to dissipate fast; LED lamp pearl temperature constantly raises, and has influenced the service life of LED lamp pearl, even just it has been burnt out at short notice.
The utility model content
The utility model technical problem to be solved provides a kind of LED lamp cooling structure, adopt this LED lamp cooling structure after, the heat that LED lamp pearl produces can spread all over entire radiator very soon, and the heat exchanger effectiveness of radiator and air is higher.
The technical scheme that the utility model technical solution problem is adopted is: this LED lamp cooling structure comprise radiator and and substrate, also comprise fixed leg, an end installation base plate of said fixed leg, the other end insert radiator.Fixed leg is sent to the heat that LED lamp pearl produces on the entire radiator, has improved radiating efficiency.
Said radiator is made up of several fins, and the space between the fin helps air flows, and has increased heat exchange area.
For further improving the flowability of air between the fin, said fin is provided with at least one through hole.
Said fin and the welding of said fixed leg are fixing, have guaranteed the seamless link of fin and fixed leg, and heat-conducting effect is better.
The beneficial effect of the utility model is: after adopting this kind LED lamp cooling structure, the heat that LED lamp pearl is produced is transmitted on the radiator more quickly, and radiator adopts the mode of fin; The area of dissipation of fin is big; Higher with the heat exchanger effectiveness of air, so radiating rate is fast, LED lamp pearl is heated up slow; Temperature can be not too high yet, thereby prolonged the service life of LED lamp pearl and whole light fixture.It is more smooth and easy that through hole on the fin flows the air between the fin, and heat can loose in air quickly, has further improved radiating efficiency.
Description of drawings
Fig. 1 is to use the front view of the light fixture of the utility model LED lamp cooling structure.
Fig. 2 is the cutaway view along A-A line among Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2; The substrate 1 that LED lamp pearl 2 is installed is fixed on an end of fixed leg 3; The other end of fixed leg 3 is inserted in the radiator, has changed the mode that LED lamp pearl in the past is fixed on radiator one end, and the heat that LED lamp pearl 2 produces is transmitted on the radiator by fixed leg 3; Fixed leg 3 is big with the contact area of radiator, has made full use of the area of dissipation of radiator.Radiator is made up of some fins 4, and these fins 4 are welded on the fixed leg 3, has both improved the heat transfer efficiency between fixed leg 3 and the fin 4, has increased the whole fastness of light fixture again.Several through holes 5 on the fin can make the air flow property between the fin 4 better, and speed air flow is fast, and air dissipates the heat on the fin 4 quickly.
Claims (4)
1.LED lamp cooling structure comprises radiator and substrate (1), it is characterized in that: also comprise fixed leg (3), an end installation base plate (1) of said fixed leg (3), the other end inserts in the radiator.
