Abstract

The utility model relates to a heat-dissipation device of a high-power LED head lamp; a lamp holder and a heat-dissipation plate are embedded, a bottom plate is sheathed in a groove of two side beams,a supporting base and a closing plate are fixed at two ends of the side beam by bolts to form a lamp holder body; the heat-dissipation plate is composed of a plurality of single-row cactoid heat-dissipation fins which are arranged at interval in a high-low way, a plurality of the heat-dissipation fins are arranged on the back surface of the bottom plate of the lamp holder, and the heat-dissipation fins can be combined according to the power level of an LED lamp; the front surface of the lamp holder and the heat-dissipation fins are provided with an LED base plate and a lamp shade correspondingly; by adopting the structure, heat produced by the high-power LED can be transmitted to the heat-dissipation fins after being temperature-equalized through a metal base plate and the bottom plate ofthe lamp holder, and the heat-dissipation fins with special shape can carry out heat exchange process by thermal convection, thereby having heat-dissipation function of the LED. The heat-dissipationdevice has the characteristics of simple structure, artistic appearance, compact structure, good permeability of natural heat dissipation and high efficiency and the like.

Description

A kind of heat abstractor of high-power LED illuminating lamp

Technical field

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

Background technology

Since white light LEDs in 1998 was succeeded in developing, people just expectation can use led light source and replace conventional light source, particularly in recent years along with the rapid lifting of the lumen number of LED, had just promoted the realization of these wonderful dreams of people more apace.

At present, the exploitation of high-power LED light source has been tended to one hundred daysization with using, 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 high-power LED illuminating 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:

A kind of heat abstractor of high-power LED illuminating lamp mainly is made up of curb girder, carrier base, shrouding, base plate, fin, LED lamp substrate, LED lamp and lampshade etc.Lamp socket and heat radiation plate are mosaic combined structure, and lamp socket is divided into carrier base, curb girder, base plate and shrouding, and the heat radiation plate is made up of the fin of the alternate celestial being's palmate of a plurality of single height, and fin 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 in the two ends of curb girder, make it to form lamp socket integral body with bolting; A plurality of fin are arranged the back side that is installed on lamp holder base plate, positive corresponding installation LED substrate with fin of lamp socket and lampshade.

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, reasonable in design, compact conformation, 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, easy for installation;

5, combination is flexible, applied widely.
