Abstract
The utility model discloses an LED radiating device comprising a heat collecting part, a heat conducting part and a radiating fin terminal; the heat collecting part is arranged on the top part of the radiating fin terminal and is fixedly connected with the radiating fin terminal; and the heat conducting part is arranged inside the heat collecting part and the radiating fin terminal. In the utility model, the LED radiating device has simple structure, is convenient for manufacturing and installation, achieves the effect of quickly conducting and cooling the temperature of the LED lamp and LED luminaire by being arranged on a single high-power LED lamp, and enhances the service life and light efficiency of the LED lamp and the LED luminaire.
Description
Technical field
The utility model relates to heat abstractor, relates in particular to a kind of LED heat abstractor.
Background technology
Fluorescent lamp is to miniaturization, high power development at present, and the surface loading of lamp increases, thereby the lamp wall temperature is increased, and too high temperature causes the luminous efficiency of lamp and life-span to descend.This phenomenon is comparatively remarkable on the LED lamp.
Summary of the invention
For solving above-mentioned middle problem and the defective that exists, the utility model provides a kind of LED heat abstractor.Described technical scheme is as follows:
A kind of LED heat abstractor comprises:
Long-pending thermal part, conducting-heat elements and radiating fin post, described long-pending thermal part is arranged on the top of radiating fin post, and is connected to one with the radiating fin post; Described conducting-heat elements is arranged on the inside of long-pending thermal part and radiating fin post.
Described conducting-heat elements is arranged on the centre position of long-pending thermal part and radiating fin post inside.
Described radiating fin post is to be made of a plurality of radiating fins, and the radiating fin post that described a plurality of radiating fin is formed is circular.
Also be provided with the drift bolt hole on the long-pending thermal part at described thermal column top, will amass the fixing also driving fit of thermal column of thermal part connection on the LED lamp plate by the drift bolt hole of its setting.
The beneficial effect of the technical scheme that the utility model provides is:
Simple in structure, manufacturing and easy for installation by being arranged on single the high-capacity LED lamp, reach the temperature of quick conduction and cooling LED lamp and LED light fixture, but also have strengthened the life-span and the light efficiency of LED lamp and LED light fixture.
Description of drawings
Fig. 1 is overall structure figure of the present utility model;
Fig. 2 is the long-pending thermal part structural representation of the utility model;
Fig. 3 is the utility model conducting-heat elements structural representation;
Fig. 4 is the utility model thermal column profile.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, the utility model embodiment is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, showed overall structure of the present utility model, this structure comprises long-pending thermal part 13, conducting-heat elements 12 and radiating fin post 11, wherein, long-pending thermal part 13 adopts long-pending hot aluminium flake, is arranged on the top of LED thermal column 11, and is connected to one with the radiating fin post; The radiating fin post is made of a plurality of radiating fins 41, and constitutes a circular radiating fin post (as shown in Figure 4).There are a square or circular port in middle part at long-pending hot aluminium flake and radiating fin post, to place its conducting-heat elements.Conducting-heat elements adopts heat conduction copper post screw (as shown in Figure 3), be arranged on the centre position, inside of long-pending hot aluminium flake and radiating fin post, and its conducting-heat elements is that the higher material of thermal conductivity factor is made.Also be provided with drift bolt hole 21 (as shown in Figure 2) on the long-pending hot aluminium flake at described thermal column top, will amass the fixing also driving fit of thermal column of hot aluminium flake connection on the LED lamp plate by the drift bolt hole of its setting.
The above is preferred embodiment of the present utility model only, is not limited to the utility model, and is all within spirit of the present utility model and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
