Question 1

In general, what is the main reason for LED street light flickering?

Accepted Answer

When the LED driver fails, the LED light will flicker or not light up at all. At this time, if you have a spare LED driver, it is recommended that you replace the LED driver in accordance with the relevant safety manual to observe whether the flickering phenomenon disappears. If the fault still exists, it is recommended to consult a professional.

Question 2

Why did my LED burn out?

Accepted Answer

LEDs are often very sensitive to temperature and high voltage. When a lot of heat accumulates inside the LED chips and exceeds its maximum allowable junction temperature, it often causes the LED to break down. Similarly, excessive voltage can also cause LEDs to burn out, especially when the power supply voltage suddenly increases or there is a voltage spike, the high voltage can cause the LED to overload and break down. In addition, the LED drive current is too high, the positive and negative poles are connected in reverse, and static discharge generated by the human body or equipment can also directly damage the LED, eventually leading to lamp failure.

Question 3

How to repair a burnt out LED?

Accepted Answer

The damage to the LED module is irreversible, and once the damage occurs, you can only replace it. Take the LED street light as an example. After ensuring that there is no problem with the power supply, remove the glass, screws and connections, and replace the LED module with a new one. Reconnect the wiring, assemble the glass back, and ensure that there is no problem with the waterproof performance of the lamp. Finally, power it on and check if it works properly.
