Look at the cleanliness of the surface of the LED strip. If the SMT process production of LED lamp belt, its surface cleanliness is very good, do not see what impurities and stains. However, if the copycat LED lamp strip produced by hand welding process is adopted, its surface will remain stains and cleaning traces no matter how it is cleaned. At the same time, it will help solder flux and tin residue remain on the surface of FPC. Look at the packing. The regular LED lamp belt will use anti-static coil packaging, usually 5 meters a roll or 10 meters a roll, and then the outside of the anti-static moisture-proof packaging bag seal.

Relevant data show that compared with traditional lighting, LED consumption is very low, can save about 70%. It also lasts longer than traditional lamps. Although the research and development cost in the early stage is high, the energy saving effect in the later stage can fully compensate for the investment in the early stage. The many advantages of LED energy-saving lamp are also the main reason for its long-term development. The daylight of LED lights, from a visual point of view, gives people a softer feeling, even, easy to accept.

The shape of copper outlet sheet is improved to reduce the mechanical stress caused by thermal expansion. The cracks on the LED chip, the improper use of the LED, the LED is burned after overcurrent, if the current of the LED device exceeds the limit that the device itself can withstand, it will burn the device. The main sources of high current are: the external forward voltage is too large; LED characteristics degradation; Improper heat dissipation causes device heat rush.
LED bonding wire overcurrent overheating fuse, chip cracking after overheating, LED electrostatic breakdown.
