Abstract
The utility model discloses a silicon rubber heat radiation structure for a light emitting diode (LED) aluminum base plate. The silicon rubber heat radiation structure comprises an aluminum base plate, an insulation circuit board pattern layer, an LED lamp bead and a base, wherein the LED lamp bead is welded on the insulation circuit board pattern layer through a lead-out pin, the heat radiation surface arranged at the bottom of the base is tightly pasted on the upper surface of the aluminum base plate, a silicon rubber layer is paved on the upper surface of the aluminum base layer, and the silicon rubber layer wraps the outer circumference surface of the base. The silicon rubber layer is paved on the upper surface of the aluminum base layer, the silicon rubber layer covers the outer circumference surface of the base, heat generated by the LED lamp bead can be radiated out through the aluminum base plate arranged at the bottom and can also be radiated out through a heat conducting silicon rubber layer on the periphery, and then, the heat is conducted onto the aluminum base plate through the heat conducting silicon rubber layer, so that the heat radiation efficiency of the silicon rubber heat radiation structure is greatly improved, and the temperature in a lamp body is reduced. Experiments prove that after the structure is adopted, the temperature inside the lamp body and the temperature outside the lamp body are basically identical.
Description
Technical field
The utility model relates to the LED lighting field, is specifically related to a kind of LED aluminium base silica gel radiator structure.
Background technology
Whether the work of LED lamp stablizes, LED lamp pearl life-span length; Most important with lamp body heat radiation itself, the welding natural heat dissipation is all adopted in the heat radiation of high-powered LED lamp in the market; Lamp pearl base local temperature is seriously higher; Reduced the whole service life of LED light fixture like this, radiating effect is unsatisfactory, and " energy-conservation " two words are had a greatly reduced quality.Therefore the LED light fixture that led light source is made is made up of LED, radiator structure, driver, lens, and heat radiation also is a part and parcel, if LED can not finely dispel the heat, its life-span also can receive very big influence.Because heat concentrates in the small-sized chip, chip temperature raises, and causes the sharp decrease in efficiency of penetrating of non-uniform Distribution, chip light emitting efficient and phosphor powder of thermal stress; When temperature surpassed certain value, the component failure rate is index law to be increased.Statistics shows, 2 ℃ of the every risings of component temperature, reliability decrease 10%.When a plurality of LED dense arrangement were formed lighting system, the dissipation problem of heat was more serious.Solve thermal management issues and become the prerequisite that great power LED is used.
Adopted at present entire column type LED street lamp to replace traditional incandescent lamp street lamp on the market; This entire column type LED street lamp comprises lamp body, is installed in lamp body outer power supply, LED lamp pearl and is installed in the lamp body back side respectively and positive aluminium radiating fin and Transparent lamp shade; Heat radiation for ease; LED lamp pearl is installed on the aluminium base through base, and the heat that LED lamp pearl is distributed directly exports to the main body aluminium section bar from the aluminium base of bottom and dispels the heat.Even if yet adopting so many radiator structure, this LED light fixture is in when work, and still at least 5 ℃ of its lamp body internal-external temperature differences are more than-10 ℃, and such temperature difference has had a strong impact on the service life of LED lamp pearl.
Summary of the invention
The utility model problem to be solved is, to the deficiency of above-mentioned technology, designs a kind of simple in structure, long service life, can effectively guarantee the corresponding to LED aluminium base of internal and external temperature silica gel radiator structure.
The utility model is that the technical scheme that its problem of solution is adopted is:
A kind of LED aluminium base silica gel radiator structure; Comprise aluminium base, insulating circuit board figure layer, LED lamp pearl and base; LED lamp pearl is welded on the insulating circuit board figure layer through leading foot; The radiating surface of base bottom is close to the upper surface of aluminium base, and the upper surface of said aluminium base is equipped with a silica gel layer, and this silica gel layer wraps the outer circumference surface of base.
In the utility model, the height of said silica gel layer is parallel to the height of base.
In the utility model, said silica gel layer is made up of heat conductive silica gel.
The beneficial effect of the utility model is: the utility model is equipped with a silica gel layer at the upper surface of aluminium base; This silica gel layer wraps the outer peripheral face of base, and the heat that LED lamp pearl is produced not only can shed through the aluminium base of bottom, also can shed through the thermal conductive silicon glue-line of periphery; The thermal conductive silicon glue-line conducts heat on the aluminium base rapidly again; Thereby improved its radiating efficiency greatly, reduced the temperature in the lamp body, through the experiment proof; After adopting this structure, the lamp body internal-external temperature difference is consistent basically.Further, be equipped with a silica gel layer at the upper surface of aluminium base, waterproof, protection against the tide, antirust effect are played, the service life that a nearlyer step ground improves the whole LED lamp in the bottom of the also salable LED lamp of this silica gel layer pearl.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the structural representation of present embodiment;
Fig. 2 is A-A direction cutaway view of Fig. 1.
The specific embodiment
With reference to Fig. 1, Fig. 2; That the utility model provided was a kind of simple in structure, long service life, can effectively guarantee the corresponding to LED aluminium base of internal and external temperature silica gel radiator structure; Comprise aluminium base 1, insulating circuit board figure layer 2, LED lamp pearl 3 and base 4, LED lamp pearl 3 is welded on the insulating circuit board figure layer 2 through leading foot, and the radiating surface of base 4 bottoms is close to the upper surface of aluminium base 1; The upper surface of said aluminium base 1 is equipped with a silica gel layer 5, and this silica gel layer 5 wraps the outer circumference surface of base 4.
As preferred embodiment, the height of said silica gel layer 5 is parallel to the height of base 4, in the present embodiment, and the height basic horizontal of the height of silica gel layer 5 and base 4.
Further, said silica gel layer 5 is made up of heat conductive silica gel.This heat conductive silica gel can be worked under-40 ℃ ~ 250 ℃ environment, and adaptability is strong.After silica gel solidified, air-tightness was good, can play waterproof, protection against the tide, antirust effect.Further, silica gel surface smooth degree is high, and reflecting effect is good, can further improve the efficient of illumination.
Certainly, the utility model is except above-mentioned embodiment, and other equivalent technical solutions also should be within its protection domain.
