Abstract

The invention provides a radiator used for an LED lamp. The radiator comprises a radiator body. A hollow pipe body is arranged in the middle of the radiator body. The radiator body is provided with radiating fins connected with the outer wall of the hollow pipe body. The radiating fins is in the Y shape. Each radiating fin comprises a first radiating fin body, a second radiating fin body and a third radiating fin body. The radiating fins of the radiator are designed to be in the Y shape, so that ventilation between all the radiating fins is facilitated. The structure is simple, production is easy, and the radiating size is reduced at the same radiating efficiency.

Description

A kind of heat radiator for LED lamp

Technical field

The invention belongs to LED technical field, be specifically related to a kind of heat radiator for LED lamp。

Background technology

LED illumination has three advantages main: energy-saving and environmental protection, green illumination。This makes LED become one of light source of new generation substituting conventional light source in the world today。In LED operation process, owing to being PN junction work, LED chip has fever phenomenon and produces, so heat dissipation design must be carried out for this situation。The heat produced after LED illumination lamp luminescence conducts mainly through LED-baseplate and the heat abstractor being arranged on LED。And good heat dissipation design can significantly extend the service life of LED, therefore the performance of LED light source is played vital effect by heat dissipation design。

The method solving heat dissipation problem mainly has two kinds: (1) improves the quality of lamp interior LED chip, improves the internal quantum efficiency of chip light emitting under same operating current, thus improving the luminous efficiency of chip；(2) improve the heat dissipation design outside light fixture, configure rational heat abstractor, to accelerate radiation processes。

Summary of the invention

Goal of the invention: the LED fin of a kind of perfect heat-dissipating is provided。

Technical scheme: a kind of heat radiator for LED lamp, including radiator body, it it is the body of hollow in the middle of described body, described radiator body is provided with fin, described fin is connected with the outer wall of hollow tube, described fin is Y type, and described fin includes the first fin, the second fin, the 3rd fin。The fin of Y type adds area of dissipation when not increasing heat radiation volume, is conducive to improving radiating efficiency。

Preferred as the present invention, the first described fin is provided with heat radiation projection, and heat radiation is protruding also for when not affecting air circulation, increases area of dissipation。

Preferred as the present invention, the second described fin and the 3rd fin be undulate respectively, and corrugated fin has better radiating effect than the fin of plane。

Preferred as the present invention, the described prominent place plane 1～3mm of heat radiation projection。

Preferred as the present invention, described first fin is " it " font。

Preferred as the present invention, the angle of the first fin and tube wall is 8～15 °, and the fin of Y type can be arranged on the body of hollow with the angle of inclination of 8～15 °, thus strengthening ventilation effect。

Preferred as the present invention, described first fin, the second fin, the 3rd fin length ratio be 1:2:2, increase the length of second and fin the 3rd fin, be effectively increased area of dissipation。

Beneficial effect:

The invention provides a kind of radiator for LED light device, the heat sink design of this radiator is Y type, is conducive to the air circulation between a fin, and simple in construction is readily produced, and reduces heat radiation volume under same radiating efficiency。

Detailed description of the invention

According to following embodiment, it is possible to be more fully understood that the present invention。But, as it will be easily appreciated by one skilled in the art that the content described by embodiment is merely to illustrate the present invention, and should without the present invention described in detail in restriction claims。

In Fig. 1～Fig. 3,1 is the body of hollow, and 2 is fin, and 3 is heat radiation projection, and 21 is the first fin, and 22 is the second fin, and 23 is the 3rd fin。

In Fig. 1, a kind of radiator for LED light device, including radiator body, it it is the body 1 of hollow in the middle of described body, described radiator body is provided with fin 2, described fin is connected with the outer wall of hollow tube 1, and described fin 2 is in Y type, and described fin includes first fin the 21, second fin the 22, the 3rd fin 23。

The first described fin 21 is provided with heat radiation protruding 3, and heat radiation protruding 3, also for when not affecting air circulation, increases area of dissipation。

The second described fin 22 and the 3rd fin 23 undulate respectively, corrugated fin has better radiating effect than the fin of plane。

The described prominent place plane 1～3mm of heat radiation protruding 3。

Described first fin 21, in " it " font, the first fin of "the" shape can also be uniformly distributed heat radiation protruding 3。

The angle of the first fin 21 and tube wall is 8～15 °, and the fin of Y type can be arranged on the body of hollow with the angle of inclination of 8～15 °, thus strengthening ventilation effect。
