Abstract
The utility model relates to the technical field of radiating devices, in particular to the radiating device of an LED lamp, which comprises a radiating body in the hollow tube shape, wherein, a plurality of radiating fin groups are formed on the outer lateral surface of the radiating body; the radiating fin groups are in the circular radial shape; the radiating fin groups in the radial shape have larger contact area with the air, that is, the radiating area is larger, the heat accumulated can be rapidly dissipated so as to ensure high radiating efficiency; therefore, the radiating device can be mounted in the LED lamp, so as to rapidly and timely transfer a great amount of heat generated during the operation of the LED.
Description
Technical field:
The utility model relates to the heat abstractor technical field, relates in particular to a kind of LED lamp heat-radiating device.
Background technology:
Because long service life, the energy consumption of LED (Light Emitting Diode, light emitting diode) are low, energy savings is remarkable, LED 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 to provide a kind of radiating efficiency high LED lamp heat-radiating device 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 a plurality of radiating fin groups, the rounded radiation shape of described a plurality of radiating fin groups.
Wherein, described radiating fin group is to be formed by connecting by two curved radiating fins.
Wherein, the medial surface of described heat radiator body forms projection, offers screw on the projection.
The utility model beneficial effect is:
A kind of LED lamp heat-radiating device that the utility model provides comprises the heat radiator body that is hollow tube-shape, the lateral surface of described heat radiator body forms a plurality of radiating fin groups, the rounded radiation shape of described a plurality of radiating fin groups, owing to the contact area of radiating fin group that is radiation shape 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.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described, see shown in Fig. 1,2, the utility model comprises the heat radiator body 1 that is hollow tube-shape, the lateral surface of described heat radiator body 1 forms a plurality of radiating fin groups 2, the radiation shape that described a plurality of radiating fin group 2 is rounded, because it is bigger with the contact area of air to be the radiating fin group 2 of radiation shape, promptly area of dissipation is bigger, the heat of assembling promptly can be distributed the radiating efficiency height.
The radiating fin group 2 of present embodiment is to be formed by connecting by two curved radiating fins 3, this structure can further increase the area of dissipation of heat abstractor, certainly, described radiating fin group 2 also can be formed by connecting by the radiating fin 3 of multi-disc, is not limited to two curved radiating fins 3 and is formed by connecting.
The medial surface of the heat radiator body 1 of present embodiment forms projection 4, offers screw 5 on the projection 4, so that fixedly connected with the shell of LED light fixture.
The utility model when in use, be to be fixedlyed connected with the shell of the LED light fixture of being made by aluminium alloy in the top of heat radiator body 1 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 group 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.
