Abstract
A light-emitting diode module comprises several groups of light-emitting diodes and a radiator, wherein the radiator comprises a base and a plurality of fins which are arranged on one side of the base, a plurality of heat pipes which are in the same plane with the side surface of the base are embedded on the other side of the base in the radiator, a heat conducting plate is attached on the other side of the base to contact with the heat pipes, and the light-emitting diode module is attached on the heat conducting plate. The heat pipes are embedded on the other side of the base of the radiator, and have the same plane with the base, thereby guaranteeing the whole structure of the light-emitting diode module compact and light. The heat conducting plate is attached on the other side of the base and is contacted with the heat pipes, thereby facilitating heat energy concentrated on the heat conducting plate to be transferred to the fins through rapidly passing through the base and the heat pipes, and guaranteeing the higher heat radiating efficiency of the light-emitting diode module.

Background technology
Light-emitting diode (Light Emitting Diode, be called for short LED), it is a kind of light emitting semiconductor device, it is to utilize semiconductor chip as luminescent device, by charge carrier compound energy of emitting surplus taking place causes photo emissions in semiconductor, directly send versicolor light such as white, indigo plant, the led lighting product utilizes light-emitting diode as the produced ligthing paraphernalia of light source exactly, is widely used in fields such as communication, illumination, traffic, billboards.But, high brightness, High Power LED then can Yin Wendu rising and cause luminous efficiency obviously to descend, even cause the damage of assembly, therefore, how the working temperature with led lamp keeps within the specific limits to avoid the generation of above-mentioned phenomenon, is the present urgent problems of people.At present, the common way of industry is sticked radiator to distribute its heat below LED circuitboard, as U.S. Pat 6,517, promptly disclosed a kind of light emitting diode module 218B2 number, it comprises a pedestal and the several dissipation fins of extending on this pedestal, because the simple radiating fin that relies on dispels the heat, the radiating efficiency of this heat abstractor is restricted.In order to improve radiating efficiency, can increase radiating fin quantity or increase the fin size, but made the volume of light emitting diode module excessive so, heavy.
Summary of the invention
In view of this, be necessary to provide a kind of light emitting diode module that has than high cooling efficiency and compact conformation.
A kind of light emitting diode module, comprise some groups of light-emitting diodes and a radiator, described radiator comprises a pedestal and is formed at some fin of pedestal one side, described radiator is embedded with some heat pipes with this side surface coplane of pedestal in the opposite side of pedestal, the be sticked opposite side of this pedestal and contact with heat pipe of one heat-conducting plate, described light emitting diode module is sticked on heat-conducting plate.
Above-mentioned heat pipe be embedded at radiator base opposite side and with its coplane, guarantee the integrally-built compactness of light emitting diode module, light and handy; Heat-conducting plate is attached at the opposite side of pedestal and contacts with heat pipe simultaneously, makes the heat that concentrates on heat-conducting plate reach fin by pedestal and heat pipe fast, guarantees that light emitting diode module has than high cooling efficiency.

Embodiment
See also Fig. 1 to Fig. 2, be the light emitting diode module of a preferred embodiment of the present invention, comprise that some groups of light-emitting diodes 100 reach in order to the heat abstractor (not label) to its heat radiation.This heat abstractor comprises a radiator 220, is sticked at the some heat pipes 240 of radiator 220 and the heat-conducting plate 260 of be sticked simultaneously radiator 220 and heat pipe 240.Light-emitting diode 100 heat-conducting plate 260 that closely is sticked, as light emitting source, it comprises some circuit boards 120 and the some light-emitting diodes 124 (only showing among the figure) that is parallel to each other, be interval with plurality of holes 122 on each circuit board 120, these light-emitting diodes 124 evenly are installed in the hole 122 of this circuit board 120 and electrically connect with this circuit board 120.
Radiator 220 adopts the metal or alloy of high thermal conductivity, make as copper, aluminium or albronze material, comprise the pedestal 222 of a horizontal positioned, rectangular plate shape and be formed at a side of pedestal 222, be the basal surface of pedestal 222 and the fin 224 that extends vertically downward, the opposite side of this pedestal 222, the top surface that is pedestal 222 is provided with some grooves 226 along its length direction is parallel, so that accommodate heat pipe 240 in wherein.
Each heat pipe 240 all is flat, comprise top surface 242 and the basal surface (scheme do not show) relative with top surface 242, this heat pipe 240 is weldingly fixed in the groove 226 of pedestal 222 of radiator 220, makes the top surface 242 of heat pipe 240 and the top surface coplane of pedestal 222.
This heat-conducting plate 260 is a rectangle, and its material is the metal or alloy that adopts high thermal conductivity, as copper, aluminium or albronze.This heat-conducting plate 260 is provided with first surface 262 and and first surface 262 opposing second surface (figure does not show).The second surface of this heat-conducting plate 260 closely is sticked at the top surface 242 of above-mentioned heat pipe 240 and the top surface of pedestal 222.Closely the be sticked basal surface of circuit board 120 of light emitting diode module 100 of the first surface 262 of this heat-conducting plate 260 is so that the heat that fast Absorption light-emitting diode 124 produces.
See also Fig. 3 and Fig. 4, during light emitting diode module work, the heat of its generation is at first absorbed by heat-conducting plate 260 and heat pipe 240, conducted to afterwards on the pedestal 222 of radiator 220, then, heat is dispersed in the surrounding air along the fin 224 of radiator 220 and goes, and realizes heat radiation.
