Description

There is the lamp power structure preventing Copper Foil solder joint from coming off

Technical field

The utility model relates to the circuit board tubular construction technical field in light fixture, espespecially between its circuit board and electronic building brick point be provided with location a kind of of colloid there is the lamp power structure preventing Copper Foil solder joint from coming off.

Background technology

Along with the continuous progress of human civilization, lighting device in order to illuminate human lives also constantly improves always, wherein, after Mr. Thomas Edison (ThomasAlvaEdison) invention bulb, namely mankind's lighting technology is no longer only the mode that illuminated by flame and presents, and the substitute is the bulb or lamp luminescence effect that are produced by the mode of energising.

And up to modern age, after light-emitting diode (Light-EmittingDiode, LED) lighting technology is invented, it is the same just like the invention of bulb originally, has also started the use revolution of the mankind for lighting device.In the middle of, because LED lamp tube or bulb adopt light-emitting diode as light emitting source, make its luminous efficacy higher, more energy-conservation and longer service life more environmental protection.Therefore, the most ideal product that present stage replaces fluorescent tube or bulb is namely become.
