Abstract

The utility model relates to a heat-radiating device of a combined high-power LED street lamp. A heat-radiating plate comprises a plurality of single-row high-low alternate cactus-shaped heat-radiating sheets (4), and the heat-radiating plate, a bracket seat (1), a lateral beam (2), a heat-conducting soleplate (3), a sealing plate (6) and the like form an integral lamp frame; an LED baseplate (7) is installed on the front surface of the heat-conducting soleplate (3) corresponding to the heat-radiating sheets (4), so that screws (9) for installing the baseplate are interlocked with the heat-radiating sheets (4) through the heat-conducting soleplate (3), and both ends of each heat-radiating sheet (4) are fixed on the lateral beam (2) through screws (5). Thus, the heat energy generated by a high-power LED lamp (8) is conducted to the heat-radiating sheets (4) after the heat soaking of the metal baseplate (7) and the heat-conducting soleplate (3), and the heat exchange process of the heat-radiating sheets (4) in special shapes is finished through natural convection and heat radiation to achieve the heat-radiating action of a high-power LED.

Description

A kind of heat abstractor of combined high-power LED street lamp

Technical field

The utility model belongs to the electric lighting technical field, relates to a kind of heat abstractor of combined high-power LED street lamp.

Background technology

At present, the exploitation of high-power LED light source has tended to one hundred daysization with application, and replacing conventional light source has also become a kind of trend and inevitable; Yet the energy of LED can transfer to the luminous energy except a part, wherein suitable most still to transfer heat energy to, so heat dissipation problem remains and influences that great power LED is used and a major issue of development; And this problem also directly has influence on manufacturing cost and the energy-saving effect and the service life of high-power LED lamp.

The radiating mode of the current employing of high-power LED illuminating lamp mainly contains: the integrated Natural Heat Convection of lamp socket and radiating fin, install fan forced heat radiation, heat pipe and loop heat pipe heat radiation etc. additional.Yet, it is big that the integrated Natural Heat Convection mode of lamp socket consumes wealth, weight is too heavy, give to install and use brings certain danger, and the layout of light fixture radiating fin is not considered the occupation mode of light fixture well mostly, only emphasizes heat conduction link, the harmony of ignoring heat loss through convection and heat transfer, thereby influence the performance of fin effect, also increased production cost and mounting hardness virtually, limitation is bigger; Install then system complex of fan forced heat radiation mode additional, reliability is low, needs often to safeguard, is used less so make; Though heat pipe and the cost of loop heat pipe radiating mode heat pipe own are higher and technology is complicated, good heat dissipation effect, weight are also light, and, the oxidized easily and corrosion in heat pipe surface under the condition in the open is so the heat radiation that is not suitable as street lamp is used.

Street lamp have use at outdoor night, radiating surface is positioned at towards the restricted advantage that helps the natural convection air heat radiation such as less of terrace and build, so high-power LED street lamp is more suitable for selecting the Natural Heat Convection mode.

The utility model content

The purpose of this utility model is to provide a kind of heat abstractor of combined high-power LED street lamp, with its pointed structural design for improving above-mentioned existing in prior technology defective and not enoughly provide a new solution, thereby help promoting the further application and the development of great power LED.

For achieving the above object, solution of the present utility model is:

The heat radiation plate is made up of the fin of the alternate celestial being's palmate of a plurality of single height, and the heat radiation plate can make up according to the watt level of LED lamp.Single unit system is: the base plate cover is embedded in the groove of two curb girders, and carrier base and shrouding use bolting in the two ends of curb girder; The corresponding back side that is installed on conductive sole plate of arranging of the array position of LED lamp on a plurality of fin and the positive LED lamp substrate makes the screw of installation base plate see through conductive sole plate and fin to locking, and two of fin is fixed on the curb girder with screw.Like this, the heat energy that produces by great power LED by the samming of metal substrate and lamp holder base plate after conduction give fin, the fin with special shape is finished heat exchanging process by Natural Heat Convection, thereby reaches the thermolysis of LED.

After adopting said structure, compared with prior art, the utlity model has following progressive advantage:

1, simple in structure, compact, the natural heat dissipation permeability is good, the efficient height;

2, good looking appearance;

3, volume is little, and is in light weight, and cost is low;

4, combination is flexible, easy for installation.
