The combination manner of the heat conduction and the heat dissipation is adopted, the temperature conduction plate and the heat conduction plate absorb heat generated when the integrated LED plate emits light, the heat is transmitted to the two groups of heat conduction pipes through the heat-conducting plate; the absorbent heat is dissipated through radiating fins of the heat conduction blocks on the left section and the right section of the two groups of heat conduction pipes and the two groups of radiating fins; and all dissipated heat in the lamp body is finally dissipated through radiating windows on the upper cover and the lower cover of the lamp body, so that the quick heat conduction and dissipation of the high-power LED street lamp is realized, and the service life of the street lamp is prolonged.

Description

A kind of high-power LED street lamp heat conduction and heat radiation structure

Technical field

The utility model belongs to the lighting technical field, relates to a kind of LED modulated structure, is specifically related to a kind of high-power LED street lamp heat conduction and heat radiation structure.

Background technology

LED in the lighting technical field, has advantages such as energy consumption is low, the life-span is long as light source applications of new generation.But LED can produce heat in the course of the work, if heat is not in time derived, can cause thermal accumlation, causes the shortening in LED life-span, the aggravation of LED light decay, and the bulk life time of light fixture reduces.Especially at present high-power LED street lamp has become city indispensable lighting installation at night, and high-power LED street lamp need be worked under various different external environments for a long time, and its heat dissipation problem just becomes the matter of utmost importance that influences its life-span.For solving the heat dissipation problem of high-power LED street lamp, many people have been installed fin additional at high-power LED street lamp, but the heat-transfer rate of the fin that is installed additional itself is slow, can not in time heat be derived and distribute, and improved effect does not still reach the requirement of anticipation.

Summary of the invention

The purpose of this utility model provides the structure that is suitable for a kind of high-power LED street lamp heat conduction and heat radiation, adopts the mode of heat conduction and heat radiation combination, and by heat-conductive plate and heat-conducting plate, the heat that LED is produced is delivered to heat pipe; Radiating fin and two groups of fin by heat-conducting block on the heat pipe distribute the heat that absorbs again, and the heat of LED generation distributes fully by the heat radiation window of street lamp housing the most at last, has solved the problem of existing high-power LED street lamp heat radiation.

The technical scheme that the utility model adopted is, a kind of high-power LED street lamp heat conduction and heat radiation structure, comprise integrated LED plate and driving power in the loam cake, lower cover, lamp body of road lamp body, integrated LED backboard face in the described lamp body connects heat-conducting plate through a heat-conductive plate, type groove by heat-conducting plate and heat-conducting block is with the left side section clamping of two groups of heat pipes and be fixed in loam cake, and the right section of two groups of heat pipes is set with two groups of fin; The position that described loam cake is corresponding with being placed on down two groups of fin is provided with the heat radiation window.

High-power LED street lamp heat conduction and heat radiation structure described in the utility model, its feature also be,

Described heat-conducting block is provided with radiating fin.

Heat-conducting liquid is filled in described heat pipe inside.

The utility model high-power LED street lamp heat conduction and heat radiation structure, adopt the mode of heat conduction and heat radiation combination, integrated LED backboard face in lamp body connects heat-conducting plate through heat-conductive plate and absorbs the luminous heat that produces of integrated LED plate, and the left side of the two groups of heat pipes of type groove clamping by heat-conducting plate and heat-conducting block section is delivered to heat pipe with heat; Radiating fin and two groups of fin by the heat-conducting block on the section about two groups of heat pipes distribute the heat that absorbs again; all distribute heats finally distribute through the heat radiation window of street lamp lamp body loam cake lower cover in the lamp body; realize the heat radiation of high-power LED street lamp quick conductive, the effect of having played the protection high-power LED street lamp and having prolonged its service life.
