Hello everyone, I am a dream. Today, let ’s introduce the problem of how to repair the LED lamp beads on the lights flashing the LED lamp. The following is the summary of this issue and related issues. Look.

1. How to fell after the LED light is turned on and the LED lights are fired after the lamp is turned on. 3. How to solve the light of the LED light. What is the problem with a flash?

LED Flash after turning on the lights. Flashing situations and so on. You can remove the LED light, turn on the case, and replace the LED drive power. Drive the power damage and try to replace it with professionals, so as not to operate improper lamps and more seriously damage

2. Frequent flashes of LED lights may also be due to the aging of lamp beads for a long time. Which lamp beads on the LED lamp board failed and replaced the broken lamp beads. Do not destroy the aluminum substrate when replacing the beads. The new lamp beads must be firmly fixed with the aluminum substrate

3. The frequent flashes of LED lights may also be due to the error of the fire and the neutral line. We can first remove the switch. The switch and wire are firmly connected together. Everyone loose the screws at the wiring and reintegrate the cable and the scarm. We can distinguish the fire and zero wire through the color of the wire insulation layer. If we cannot distinguish from the color, we can use the universal meter to detect the resolution of the fire line

4. The frequent flashing of the LED light may be caused by the poor heat dissipation of the lamp. Everyone can replace the lamp shell with better heat dissipation, or we paint radiation heat dissipation materials at the lamp case to strengthen the heat dissipation of the lamp.

In addition, the unstable voltage in the home will also cause the lamp to flash frequently. We can install the voltage of the regulator to stabilize the home voltage

LED light. LED lights may be due to a problem with the circuit: if the LED light is turned off, there is still a flashing situation because the neutral line fire is connected. You can re -connect the zero line and line of the switch socket. The zero lines and fire cables can be distinguished by various ways such as electrical pens, universal meters, and wires to distinguish the neutral line fire.

2, LED lights flashing may be a problem with the driving power supply: for example, the lamp beads, the driver's power does not match, you can replace a suitable driver power. Or the heat dissipation performance of the lamps is not good, resulting in too high the temperature of the lamp, and the driving power supply can open the overheating protection function. You can enhance heat dissipation by applying heat sink coatings in the lamp case.

Today's headlines

LED lamp bead flashed a flash. What are the causes of the cause of LED flashing:

1, LED lamp beads do not match the LED driver power, if the lamp chip is not enough power, it will cause Lighting light sources are frequent.

2, the LED driver has a problem with the power supply, as long as you replace it with another good driver power, you will not flash.

3. If the driver has a temperature protection function, and the material heat dissipation performance of the lamp can not meet the requirements, the driver's over -temperature protection starts to work at the beginning of work.

4. If the outdoor lamp has a frequent flashing phenomenon, it may be that the lamps are in water.

The above is the editor of Tiancheng's lighting of the LED lamp beads that flash the LED lamp.
