Description

The LED photo engine module that electric heating separates

Technical field

The utility model relates to electrical category, the LED photo engine module that particularly a kind of electric heating separates.

Background technology

As everyone knows, light-emittingdiode has been most important a kind of light emitting source in recent years, because light-emittingdiode has luminous efficiency height, long service life, not fragile, advantage such as power consumption is few, environmental protection and volume are little, early stage because luminosity deficiency usually is used in indicator lamp and display board luminous, but in recent years because the breakthrough of material and technology, the luminosity of light-emittingdiode has had very many liftings, especially the appearance of white light LED more makes the present conventional illumination device of light-emittingdiode replacement gradually.

Yet, light-emittingdiode is when long-time the use, the energy that it sent must utilize radiator effectively to discharge, shown in accompanying drawing 1 and accompanying drawing 2, general LED commonly used heat radiation module 1 includes radiator 11, aluminium base 12 and LED illuminating module 13, wherein aluminium base 12 in the form of sheets, aluminium base 12 is arranged on the radiator 11, and aluminium base 12 is provided with one deck tool insulation characterisitic and the good dielectric layer of heat-conducting effect, aluminium base 12 is provided with circuit, LED illuminating module 13 is arranged on the aluminium base 12, and LED illuminating module 13 is extended with at least one contact jaw 131, and this contact jaw 131 can electrically connect circuit; Wherein, 12 of LED illuminating module 13 and aluminium bases are coated with one deck thermal grease 132, use obtaining preferable heat-conducting effect;

By said structure, LED illuminating module 13 can utilize circuit to finish connection in series-parallel, and the heat of LED illuminating module 13 also can conduct to radiator 11 to dispel the heat by dielectric layer.

But above-mentioned LED heat radiation module 1 is in use, still has following point:

Though LED heat radiation module 1 one, commonly used can utilize aluminium base 12 to reach the effect that electrically connects and dispel the heat simultaneously, but its hot conduction sequence is to conduct to thermal grease 132 by LED illuminating module 13 earlier, thermal grease 132 conducts to heat aluminium base 12 again, aluminium base 12 conducts to heat the purpose that radiator 11 reaches heat radiation again, but the media of heat conduction is many more, amount has further caused the not good problem of radiating effect after the heat that is distributed by radiator 11 is but few more;

Though two, aluminium base 12 has the effect of electric connection and heat radiation simultaneously, but aluminium base 12 has also caused price very expensive because have the characteristic of this kind excellence, can cause the manufacturing cost height like this, all be a burden greatly to manufacturer and consumer, need be improved.
