Moreover, the LED radiating module containing the carbon materials is concise in structure and convenient to assemble.
Description
Technical field
The present invention relates to LED technical field of heat dissipation.
Background technology
LED is a kind of can be the semiconductor of visible ray by electric energy conversion, and its energy consumption is only 1/10 of incandescent lamp, 1/4 of common energy-saving lamp.LED, except the advantage with environmental protection and energy saving, also has the plurality of advantages such as the life-span is long, light efficiency is high, radiationless.Therefore, the upgraded product that LED throws light on as the next generation is the new industry with great potential.But, the light decay of LED and life-span and its junction temperature directly closely related, LED heat radiation is bad, and junction temperature is just high, and the life-span is just short.Visible, the heat radiation module of LED no-float, improves radiating effect, and the junction temperature of control LED is most important for LED product.
Summary of the invention
The present invention needs the problem solved to be to provide a kind of LED heat radiation module with the carbonaceous material of excellent heat dispersion performance.
The technical scheme that the present invention takes is as follows: a kind of LED heat radiation module of carbonaceous material, comprise radiator, for carrying the printed substrate of LED lamp bead, carbon based metal composite plate is set below described printed substrate, carbon based metal composite plate and the tight pressing of printed substrate; Carbon based metal composite plate contacts with radiator and realizes dispelling the heat.
Described carbon based metal composite plate comprises the carbon-based material of phosphorus content more than 80%, the metal material of less than 20%.
Described metal material comprises copper, aluminium, gold, silver or tin.
The fin that described radiator comprises loop connecting portion and is located in loop connecting portion, carbon based metal composite plate is located in ring-type installation portion, and carbon based metal composite plate outer ring surface and ring-type installation portion inner surface are closely crimped together.
Compared with prior art, beneficial effect of the present invention is:
(1) LED of described carbonaceous material dispels the heat in module and adopts carbon based metal composite plate as heat sink, graphite and metal are all highly heat-conductive materials, the two is better in conjunction with radiating effect according to suitable proportioning, the heat that LED can be made to produce is derived fast and is dissipated, effectively improve radiating efficiency, effectively extend LED service life;
(2) the LED heat emission module structure of described carbonaceous material is succinct, easy to assembly.
Accompanying drawing explanation
Fig. 1 is the LED heat radiation module detonation configuration figure of carbonaceous material of the present invention.
Detailed description of the invention
For the ease of the understanding of those skilled in the art, below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
As shown in Figure 1, the LED heat radiation module of the carbonaceous material described in the present embodiment comprises radiator 20, for carrying printed substrate 10, the carbon based metal composite plate 30 of LED lamp bead.Radiator 20 comprises an annular connecting portion 21, annular connecting portion 21 one end arranges fin 22, printed substrate 10 fits tightly in carbon based metal composite plate 30, the two is located in ring-type installation portion jointly, carbon based metal composite plate 30 outer ring surface 31 contacts with ring-type installation portion inner surface, carries out heat transmission.
Wherein, carbon based metal composite plate comprises the carbon-based material of phosphorus content more than 80%, the copper of less than 20%, aluminium, the metal material that the thermal conductivity such as gold, silver or tin is good.
The LED heat radiation module of carbonaceous material of the present invention, adopts carbon based metal composite plate, realizes good heat conductive and heat sinking function.When carbon based metal composite plate makes, by after graphite base again with metal ion compound, graphite and metal ion combine density and the intensity that can improve composite, and heat-conducting effect is better, and material with carbon element can be reused, and can not produce pollute environment.
Above-described embodiment is preferrred embodiment of the present invention; it should be noted that; when not deviating from the present invention's spirit and essence thereof; those of ordinary skill in the art are when making various corresponding change and distortion according to the present invention, but these change and are out of shape the protection domain that all should belong to the claim appended by the present invention.
