Preferably, above-mentioned heat conduction support chip is copper sheet or aluminium flake, and above-mentioned protective layer is the aluminium layer, and illuminator is the LED of lighting at two sides or the double-side LED that two LEDs constitute back-to-back.

Particularly, above-mentioned heat conduction supporting layer one is rectified the reverse side punching press has said round table-like groove, and said line layer is provided with to heat conduction supporting layer other end direction from slot opening.

Further; Above-mentioned line layer comprises illuminator link, power connector end and connects the circuit of the two; Said illuminator link is provided with along said slot opening edge, and said protective layer covers said circuit, and said power connector end is exposed to said protective layer termination so that and electric power connecting.

Again further, above-mentioned protective layer length is less than said heat conduction support chip, and an end of this protective layer extends along heat conduction support chip length direction with the concordant setting of said heat conduction support chip, the other end.

Preferably, above-mentioned copper sheet thickness is 2mm, and depth of groove is 0.5mm, directly is 2.2mm at the bottom of the groove, and bore is 2.6mm, and said aluminium layer thickness is 0.45mm, and Circularhole diameter is 5mm.

Can know by above-mentioned description, compare the utility model tool with prior art the utility model structure

Following advantage is arranged:

1, the direct insertion support of this novel lighting at two sides light source can directly be fixed on chip on the heat transfer support plate, and it is simple and compact for structure, and is easy for installation, and the volume that takes up room is little.

2, this direct insertion support has adopted the positive and negative punching press that the heat conduction support chip of round table-like groove is arranged; Can switch on electric power connecting after only need fixing chip; Need not to adopt aluminium base and solder(ing) paste or heat conductive silica gel; Its thermal resistance significantly reduces, and thermal diffusivity is good, has solved existing LED application end and has made thermal resistance become big, the not good problem of radiating effect on the aluminium base because use solder(ing) paste or heat-conducting cream are welded on LED.

3, the equal punching press of the positive and negative of this light source bracket copper sheet has the fixedly round table-like groove of illuminating source; Only need a heat conduction support chip can realize that 360 ° on two sides is luminous; Light extraction efficiency is good, has also reduced the bonding process of traditional copper coin when having saved material, has reduced production cost.
