Abstract
The utility model provides a kind of LED circuit board antistatic attachment structure, including a LED circuit board and a radiator, the LED circuit board and a plurality of connecting holes of radiator formation mutual cooperation are simultaneously connected with each other by the connecting hole, the one Lu Tong areas of LED circuit board formation, the Lu Tong areas connect the earth terminal of the radiator and the LED circuit board internal circuit.A kind of LED circuit board antistatic attachment structure of the present utility model, has the advantages that simple in construction and anti-static effect is good.
Description
Technical field
The utility model is related to vehicle lamp field, more particularly to a kind of LED circuit board antistatic attachment structure.
Background technology
At present, LED/light source turns into the main stream light sources of automobile lamp.LED theoretical service lives length of about 100,000 hours, but
Actual life is more closely bound up using factors such as design, production process, use environments with LED.Wherein, static discharge
(ESD) LED electrostatic damages and electrostatic breakdown are the Main Patterns of current LED failure caused by, and static discharge has following features：
It is disguised：Electrostatic is ubiquitous, and is difficult to be perceived.
Randomness：Influence of the electrostatic to LED entirely produces and used process through it, and randomness is very big.
Potentiality：Electrostatic causes LED partial properties parameter to occur slight deterioration without influenceing its function, but can be in the later stage
Show in.
Still lack a kind of preferable LED circuit board attachment structure of antistatic performance at present.A kind of existing LED circuit board with
The mounting structure of radiator is referring to Fig. 1, be not provided with electrostatic prevention structure in LED circuit board, LED circuit board 1 and radiator 2 pass through
The cold riveting structure 21 for being formed at radiator 2 is connected, manufacturing procedure and more, the process line of processing needed for cold riveting structure 21
It is complex, while the conformity of the LED circuit board and radiator after the connection that is relatively hard to keep.
The content of the invention
For above-mentioned deficiency of the prior art, the utility model provides a kind of LED circuit board antistatic attachment structure, tool
Have the advantages that simple in construction and anti-static effect is good.
To achieve these goals, the utility model provides a kind of LED circuit board antistatic attachment structure, including a LED
A plurality of connecting holes of wiring board and a radiator, the LED circuit board and radiator formation mutual cooperation simultaneously pass through institute
State connecting hole interconnection, the one Lu Tong areas of LED circuit board formation, the Lu Tong areas connection radiator and the LED
The earth terminal of wiring board internal circuit.
Preferably, the Lu Tong areas are arranged at connecting hole periphery at least described in one.
Preferably, the Lu Tong areas are annular in shape.
Preferably, the LED circuit board and the radiator are close by the metallic screw being arranged in the connecting hole
Laminating is connected.
The utility model makes it have following beneficial effect as a result of above technical scheme：
Lu Tong areas connect radiator and are grounded so that the electrostatic charge of product can pass through on radiator and LED circuit board
Earth terminal is discharged, so that playing prevents the effect of electrostatic.The LED circuit board and the radiator are described by being arranged in

Refer to Fig. 2 and Fig. 3, a kind of LED circuit board antistatic attachment structure that the utility model is implemented, including a LED
The radiator 2 of wiring board 1 and one, LED circuit board 1 and radiator 2 form a plurality of connecting holes 31 of mutual cooperation and by wearing
It is connected with each other in the screw 32 in connecting hole 31, one Lu Tong areas 11 of the formation of LED circuit board 1, in the present embodiment, Lu Tong areas 11 are set
In the periphery of a connecting hole 31, Qie Lutong areas 11 are annular in shape, and the connection radiator 2 of Lu Tong areas 11 and the internal circuit of LED circuit board 1 connect
Ground terminal.
The connection radiator 2 of Lu Tong areas 11 is simultaneously grounded so that the electrostatic charge of product can be with radiator 2 and LED circuit board 1
Discharged by earth terminal, so that playing prevents the effect of electrostatic.LED circuit board 1 and radiator 2 are by being arranged in connecting hole
Metallic screw in 31 is brought into close contact connected, it is ensured that Lu Tong areas 11 and the connection of radiator 2, it is ensured that electrostatic discharged stabilization
Degree, while simplifying manufacturing procedure and process line, improves production efficiency.And with simple in construction, mould modification is convenient
The good advantage with anti-static effect.
The utility model is described in detail above in association with accompanying drawing embodiment, those skilled in the art can root
Many variations example is made to the utility model according to described above.Thus, some of embodiment details should not be constituted to this practicality
New restriction, the utility model regard the scope defined using appended claims as protection domain of the present utility model.
