In order to realize the present invention better, be respectively arranged with first wire welding area and second wire welding area on the both sides platform of said bullion cantilever tip platform; Said two groups of above LED point-source of lights are through first wire welding area and second wire welding area being electrically connected with realization and outside.First wire welding area and second wire welding area can be for the bonding wire platforms of any conductor manufacturing or can be realized other modes of being electrically connected making things convenient for the LED point-source of light to realize being electrically connected.
Said first wire welding area and second wire welding area are meant the conductor bar on the both sides platform that is separately fixed at bullion cantilever tip platform; Said two groups of above LED point-source of lights are through conductor bar being electrically connected with realization and outside.
The plane of the plane, top of said conductor bar and bullion cantilever tip platform is same horizontal plane.The area (conductor simultaneously also can transmit heat) of conductor bar to increase heat radiation placed in the space that can make full use of the both sides platform so on the one hand; On the other hand conductor bar can with " mouth " shape of bullion support formation rule, convenient whole encapsulation.
In said two groups of above LED point-source of lights, all LED point-source of light parallel connections in every group of LED point-source of light; Connect between the group.The connected mode of all LED point-source of lights can be with current uniform in every group of LED point-source of light; Be distributed to a plurality of parallel circuitss; Reduce of the influence of the fault of single LEDs point-source of light: promptly adopt such connected mode to whole light source; Individual point light source in same group breaks down, and can not influence the luminous of entire chip.
In said two groups of above LED point-source of lights, every group of interior LED point-source of light quantity of LED point-source of light equates.Can make the light-emitting line of the LED luminescence chip that the LED point-source of light forms average, consistent like this.
As preferably, said bullion support is meant the aluminum metal support.The perfect heat-dissipating of aluminum metal uses it can reduce the production cost of LED lamp as metallic support simultaneously.
A kind of LED lamp that is formed by above-mentioned New LED luminescence chip assembling, it is characterized in that: the New LED luminescence chip by more than two is composed in series.
The present invention uses like this: shown in Fig. 4 New LED luminescence chip internal circuit schematic diagram; Two groups of above LED point-source of lights are connected successively; All LED point-source of light parallel connections are electrically connected in every group of LED point-source of light; Circuit power is arranged on the left side of LED luminescence chip, and the sense of current through the LED luminescence chip is from left to right.LED lamp by the assembling of New LED luminescence chip forms then is composed in series by the New LED luminescence chip more than two successively.
The present invention possesses following outstanding advantage and effect with respect to prior art:
1, New LED luminescence chip of the present invention is when assembling; Only need the LED point-source of light more than two groups is adjacent on the bullion support that is arranged in heat radiation; Draw to encapsulate behind the lead again and get final product, it is simple for assembly process, can improve the packaging efficiency of LED luminescence chip greatly.
2, the present invention has changed the radiating mode of LED point-source of light, has improved the heat dispersion of LED luminescence chip, thereby prolongs the useful life of LED luminescence chip.
3, reaching on the basis of identical radiating effect, radiating mode of the present invention has been saved 50% heat conduction aluminium section bar than the radiating mode that existing use paster lamp pearl adds aluminium base, has reduced the production cost of LED luminescence chip.
