Description

The LED lamp radiating module

Technical field

The utility model relates to a kind of heat abstractor, particularly a kind of radiating module as the heat radiation of LED light fixture.

Background technology

Under the leading of new material and technology, light emitting diode has developed into now has that volume is light and handy, reaction speed reaches advantages such as pollution-free soon, thereby makes light emitting diode be used in gradually in the various fields.Though the brightness of early stage of development light emitting diode still has deficiency slightly, lead down in the exploitation of more new materials, the advantage that replaces traditional lighting has gradually been arranged.

The particularly present High Power LED that develops, under the influence of new material, in order to make the best luminous benefit of High Power LED performance, its required electric current also increases day by day, the effect heat that is produced also significantly promotes relatively, because too much heat accumulation can shorten the service life of light emitting diode, therefore select suitable heat radiation countermeasure to become a considerable ring.

For now, radiator fan is to be modal heat dissipation, by the forced draft that fan produced, can be fast with the effect torrid zone that electronic building brick produced from, to reach the thermolysis that it has, though fan has pretty good radiating effect, fan has certain volume, but is not suitable for the light and handy light emitting diode of volume.

Therefore known technology is just taked another kind of common radiating mode, and promptly the radiator of forming by a plurality of fin with conduction of heat is used as the heat radiation countermeasure of light emitting diode.Via the heat conduction property of radiator itself,, produce heat exchange action via radiating surface and the outside air that a plurality of fin had again, to reach the thermolysis that it is had fast with after the effect heat absorption that light emitting diode produced.Yet, because the radiating efficiency of radiator depends on the number of heat transfer efficiency and area of dissipation, the circulation that cooperates outside air simultaneously with the heat band from, though known radiator has enough area of dissipations, but because the conduction efficiency of radiator is not enough to deal with a large amount of heats of generation, thereby make its thermolysis have a greatly reduced quality, certainly will will seek another kind of heat radiation countermeasure again and solve the difficulty that is met with at present.

The utility model content

At above-mentioned defective, main purpose of the present utility model is to provide a kind of LED lamp radiating module with high conduction efficient

In order to reach above-mentioned purpose, the utility model provides a kind of LED lamp radiating module, described modular structure mainly comprises radiator, heat pipe, heat-conducting seat and press body, wherein said radiator is made up of a plurality of fin, offer at the middle position of each fin and to wear groove, described heat pipe is a U type pipe, have heat absorbing end and condensation end on it, described condensation end is arranged on the described radiator, and described heat-conducting seat is in the form of annular discs, and with the heat absorbing end of heat pipe paste mutually to, the last described body that presses combines with described heat-conducting seat, and fix the heat absorbing end of described heat pipe and the relative position of heat-conducting seat, thereby finish the thermolysis of LED light fixture fast.

Compared with prior art, the beneficial effects of the utility model are, by heat pipe is arranged on the radiator, the heat-conducting seat of high thermal conductivity coefficient of arranging in pairs or groups simultaneously absorbs the heat that the LED light fixture is produced, to quicken heat conduction efficiency, thereby the effect heat that the LED light fixture is produced outwards derives fast, carries out the air cooling thermolysis by formed radiating surface of fin and outside air more at last.
