Why is solar street light damaged and what are the reasons1

1. Sudden rise in power supply voltage. There are many reasons for the sudden increase of the power supply voltage. For example, the quality of the power supply of Shenzhen Best Optoelectronics Co., Ltd., or the improper use of the user, etc., may cause the power supply voltage to suddenly increase. 2. The short circuit of a component or printed line or other wire in the line forms a partial short circuit of the LED power supply path, which increases the voltage in this place. 3. A certain LED is damaged due to its own quality and thus forms a short circuit, and its original voltage drop is transferred to other LEDs. 4. The temperature in the lamp is too high, which makes the characteristics of the LED strip brand deteriorate. 5. Water has entered the interior of the lamp, and the water is conductive. 6. The anti-static work was not done well during assembly, so that the interior of the LED has been damaged by static electricity. Although normal voltage and current values u200bu200bare applied, it is very easy to cause damage to the LED. These reasons will cause a significant increase in the LED current, and soon the LED chip will be burned due to overheating. According to our experience, most of the LEDs are short-circuited after burning, and a few are open-circuited. Each LED has a voltage drop of about 3.2V. If it is burned out, if the LED is disconnected, the LED will not emit light. If the voltage is short-circuited, it will be transferred to other LEDs, resulting in a larger current of other LEDs, other LEDs will be burned faster, and even the power supply will be critical. Originally, a small damage can easily lead to a major accident. LEDs are generally installed at high places, which is not easy to install, and even more difficult to maintain. Therefore, the protection of LEDs is an actual demand, but at present, the definition, use, supply and purchase information and industry information of LED lamp beads have not been taken seriously by everyone, and it is also a problem that many people have no choice but to solve.
