Abstract
The utility model discloses an LED lamp heat radiation device. The heat radiation device (2) is arranged on the outer circumference of a lamp holder (1) and at least one LED lamp (3) is arranged inside the lamp holder (1). The heat radiation device (2) is formed by a plurality of axially arranged radiating fins (20). The radiating fins (20) are inclined and bent toward the same circumference direction so as to form a cylindrical structure. The arc-shaped transition segments of the radiating fins (20) are in different diameters of the cylindrical structure. According to the utility model, the radiating fins (20) in different diameters of the cylindrical structure adopt the arc-shaped transition mode. Therefore, the length of the radiating fin in the same diameter of the cylindrical structure is increased and the heat radiation effect of the LED lamp is improved.
Description
Technical field
The utility model relates to the LED technical field of lamps, relates in particular to a kind of LED heat sink for lamp.
Background technology
Improve constantly along with what lighting effects were required, the LED light fixture has obtained using widely, and the heat radiation solution of LED light fixture is the key factor in the LED lamp applications.
In the prior art, the radiating effect of LED light fixture mainly dispels the heat through fin, and the heat that the LED lamp produces in the course of the work is passed to fin, through fin heat is discharged.In LED lamp heat radiation process, the size of fin is one of key factor of radiating effect, and under all identical situation of other factors, the radiating effect of large scale fin is superior to the radiating effect of small size fin.And the overall structure of fin needs and the structure of LED lamp is complementary, and therefore, on the basis that does not change existing LED lamp design, the size that how to improve fin becomes assistant officer's technical problem to be solved in the prior art to improve its radiating effect.
The utility model content
Said based on prior art, the utility model provides a kind of LED heat sink for lamp, it has good LED lamp radiating effect.
To achieve these goals; The utility model provides a kind of LED heat sink for lamp; Heat abstractor 2 is arranged on the excircle of lamp holder 1, and at least one LED lamp 3 is set in lamp holder 1, and heat abstractor 2 is made up of axial arranged multi-disc fin 20; Multi-disc fin 20 constitutes cylindrical structural along same circumference direction oblique bending, and every fin 20 is that arc is excessive at the different-diameter place of cylindrical structural.
Preferably, fin 20 constitutes for metal material.
A plurality of fin constitute cylindrical structural along same circumference direction oblique bending; Each fin is that arc is excessive at the different-diameter place of cylindrical structural; Under two sections body diameters and all identical situation of size of the prior art; The excessive mode of the circular arc of each fin has improved the length of fin in the utility model, thereby has improved the radiating effect of LED lamp.
Description of drawings
Fig. 1 is the structural representation of a kind of LED heat sink for lamp of the utility model proposition.
Fig. 2 is the explosive view of a kind of LED heat sink for lamp of the utility model proposition.
The specific embodiment
To combine the accompanying drawing in the utility model below, the technical scheme in the utility model is carried out clear, complete description, obviously, described embodiment is a part of embodiment of the utility model, rather than whole embodiment.Based on the embodiment of the utility model, the every other embodiment that those of ordinary skills are obtained under the prerequisite of not making creative work belongs to the scope that the utility model is protected.
As shown in Figure 1, the structural representation of a kind of LED heat sink for lamp that proposes for the utility model embodiment, as shown in Figure 2, the explosive view of a kind of LED heat sink for lamp that proposes for the utility model embodiment.
With reference to accompanying drawing, the LED lamp comprises lamp holder 1, lamp socket 4 and Cap casing 5, wherein, at least one LED lamp 3 is set in lamp holder 1, and lamp holder 1 is fixedly connected with lamp socket 4, and lamp socket 4 electrically connects as 3 power supplies of LED lamp with supply unit, is provided with Cap casing 5 at the front end of lamp holder 1.
In order to solve the defective that exists in the prior art; The utility model provides a kind of LED heat sink for lamp; Heat abstractor 2 is arranged on the excircle of lamp holder 1; Heat abstractor 2 is made up of axial arranged multi-disc fin 20, and multi-disc fin 20 constitutes cylindrical structural along same circumference direction oblique bending, and every fin 20 is that arc is excessive at the different-diameter place of cylindrical structural.As shown in the figure; Multi-disc fin 20 forms two sections column structures of different-diameter; The appearance and size of column structure that diameter is bigger and lamp holder 1 is complementary; The appearance and size of column structure that diameter is less and lamp socket 4 is complementary, and every fin 20 is that circular arc is excessive at the different-diameter place of two sections cylindrical structurals.
A plurality of fin 20 constitute for metal material in the utility model.
In the utility model; The multi-disc fin constitutes cylindrical structural along same circumference direction oblique bending; Every fin is that arc is excessive at the different-diameter place of cylindrical structural, and under two sections body diameters and all identical situation of size of the prior art, the excessive mode of the circular arc of its fin has improved the length of fin; In the LED lamp course of work; The heat that the LED lamp produces is passed to fin and realizes that it has better LED lamp radiating effect in the process of radiating effect, thus the service life of having improved the LED lamp.
Combine accompanying drawing that the utility model has been carried out exemplary description above; Obviously the realization of the utility model does not receive the restriction of aforesaid way; As long as adopted method design of the utility model and the various improvement that technical scheme is carried out; Or the design of the utility model and technical scheme are directly applied to other occasion without improving, all in the protection domain of the utility model.
