Abstract
The utility model relates to the technical field of heat dissipation devices, in particular to a heat dissipation device of a light-emitting diode (LED) lamp, which comprises a hollow cylindrical heat dissipation body, wherein heat dissipation fins which are arranged at equal intervals are formed on the outer side surface of the heat dissipation body, the contact area between the heat dissipation fins and air is larger, namely the heat dissipation area is larger, the gathered heat can be rapidly dissipated, and the heat dissipation efficiency is high; therefore, will the utility model discloses install in LED lamps and lanterns, can in time rapidly lead away a large amount of heats that the LED during operation produced.
Description
Technical field:
The utility model relates to the heat abstractor technical field, relates in particular to a kind of heat abstractor of LED light fixture.
Background technology:
In recent years, LED (Light Emitting Diode, light emitting diode) has been widely used in the daily life as light source, as lightings such as cup lamp, shot-light, auto lamps.Yet along with the increase of LED quantity in the LED light fixture and high-power, high-brightness LED etc. are developed successively, the heat that is produced during the work of LED light fixture is just progressively upwards soaring.Therefore, the heat that how the LED light fixture is produced looses rapidly, becomes the significant problem that present LED light fixture technology must solve.
The radiator structure of existing LED light fixture, mainly be that shell by the aluminium base that installs and fixes LED, aluminium alloy manufacturing constitutes, aluminium base and shell utilize the heat conductivility of self, and the heat that produces when LED is worked is led away, still, because the volume of aluminium base is less, cause radiating efficiency not high, and the shell of LED light fixture, owing to be subjected to the restriction of face shaping, its radiating effect is relatively poor, and a large amount of heats that produce in the time of can not in time promptly LED being worked are led away.
The utility model content:
The purpose of this utility model is exactly the heat abstractor that the high LED light fixture of a kind of radiating efficiency is provided at the deficiency of prior art existence.
To achieve these goals, the technical solution adopted in the utility model is:
It comprises the heat radiator body that is hollow tube-shape, and the lateral surface of described heat radiator body forms two-layer radiating fin of being no less than of equidistant arrangement.
Wherein, described radiating fin is annular.
Wherein, offer screw on the radiating fin of described heat radiator body top layer.
Wherein, offer locating slot on the radiating fin of described heat radiator body top layer.
The utility model beneficial effect is:
The heat abstractor of a kind of LED light fixture that the utility model provides comprises the heat radiator body that is hollow tube-shape, the lateral surface of described heat radiator body forms two-layer radiating fin of being no less than of equidistant arrangement, the contact area of described radiating fin and air is bigger, be that area of dissipation is bigger, the heat of assembling promptly can be distributed the radiating efficiency height.Therefore, the utility model is installed in the LED light fixture, a large amount of heats that produce in the time of can in time promptly LED being worked are led away.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a vertical view of the present utility model;
Fig. 3 is the A-A cutaway view of Fig. 2.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described, see shown in Fig. 1,2,3, the utility model comprises the heat radiator body 1 that is hollow tube-shape, the lateral surface of described heat radiator body 1 forms two-layer radiating fin 2 of being no less than of equidistant arrangement, and wherein, described radiating fin 2 is annular, because radiating fin 2 is bigger with the contact area of air, be that area of dissipation is bigger, the heat of assembling promptly can be distributed the radiating efficiency height.Therefore, the utility model is installed in the LED light fixture, a large amount of heats that produce in the time of can in time promptly LED being worked are led away.
The utility model when in use, be the radiating fin 2 of heat radiator body 1 top layer to be fixedlyed connected with the shell of the LED light fixture of being made by aluminium alloy by screw, thereby the heat that produces when making LED work can reach heat radiator body 1 by the shell of LED light fixture, is in time promptly distributed by the radiating fin 2 that is molded over heat radiator body 1 lateral surface again.
Certainly, the above only is preferred embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
