At present, vertical structure LED can be divided into GaP - based LED, GaN - based LED and ZnO - based LED according to materials. The leds are electrically connected to the heat sink or the positive and negative electrodes (red and black respectively) on the PCB or circuit board.

Need to pay attention to the electric iron to use anti-static iron, at the same time maintenance personnel must also be ready to anti-static measures (such as wearing electrostatic ring and anti-static knuckles, etc.). Continuing high temperature, the LED lamp strip consists of two main components, LED and FPC.

Second, the problem of massive transfer, mass production requires that the bad point rate of transfer is less than one in a million, but at present, it only reaches one in 100,000, and the repair cost is relatively large. Third, the electrode connection problem, the electrode connection flip process cost is too high, the current domestic can only use formal process, reduce the reliability of the product; Fourth, the driving problem, it is urgent to develop refined PCB backboard manufacturing and TFT backboard driving technology; Fifth, the splicing problem, the existing splicing process can only achieve remote visual seamless, smooth seamless splicing is more difficult.

The lamps have the function of dust prevention and rain prevention, but it can not reach the level of immersion in water, so we must pay attention to the installation, then the exposed wiring we are generally directly docking with the main line at the scene, and the LED lamp outlet line is about 30-50cm long. How to ensure water resistance and leakage after connecting with the main line connector? The engineering solutions are, In the LED wiring position, install a waterproof junction box wire head in the junction box, which can play a double protection.
