1. What is the reason for the flickering of the led panel light

There are usually several reasons for the flickering of Led Panel Lights:

1. The chip of the power supply is overheated and the heat dissipation is not good. If the driver has an over-temperature protection function, but the heat dissipation performance of the lamp material cannot meet the requirements, the over-temperature protection of the driver will start to work and there will be a phenomenon of flickering, for example: 20W floodlight The shell is used to assemble 30W lamps, and this will happen if the heat dissipation is not done well.

2. The LED lamp bead does not match the LED drive power supply

Normally, a single full 1W lamp bead can withstand current: 280-300mA, voltage: 3.0-3.4V, if the lamp bead chip is not of sufficient power, it will cause the light source to flicker, and the lamp bead will turn on and off when the current is too high. In serious cases, the gold wire or copper wire built into the lamp bead will be burnt, causing the lamp bead to not light up.

3. The drive power is broken

If the drive power supply is broken, just replace it with another good drive power supply, and it will stop flashing.

4. Poor power capacitor

When there is a bad power supply capacitor, turn on the light for a while, and the capacity will drop, which will cause the light to flash.

5. Water enters the lamps and lanterns

If the outdoor lamps also flicker on and off, it means that the lamps have entered the water. The consequence is that it will not light up after flashing. The lamp bead and driver are broken. If the driver is waterproof, it is only necessary to break the lamp bead and replace the light source.

2. How to repair the Led Flat Panel Light strobe

1. Whether the LED light is on or not, you first need to check whether the circuit is good and connected, and use a pencil to check whether there is current or voltage in the circuit.

2. If there is no problem with the circuit, then check the LED light driver.

3. After powering on the LED lamp, the bulb still does not light up, you can use another driver to check whether it is on.

4. If it flickers when it is turned off, you need to eliminate the problem of the circuit first, the switch is in contact with the live wire, and the neutral wire is in contact with the electrical appliance.

3. Four common problems of LED panel lights

1. Packaging failure refers to the quality damage of components caused by incorrect packaging design or production process. The epoxy resin material used for packaging will deteriorate during the use of Dongguan LED panel lights, resulting in a decrease in the service life of the LED panel lights. It will also cause problems such as refractive index, light transmittance, hardness, expansion coefficient, air permeability, water permeability, and filler function.

2. Chip failure refers to the failure of the chip itself or other reasons. This is why LED panel light manufacturers control the low price of LED panel lights by purchasing chips with very poor quality.

3. Electrical overstress failure means that if the LED light source is used under overcurrent (EOS) or electrostatic shock damage (ESD), the chip will be damaged, resulting in an open circuit of the chip, resulting in electrical overstress failure.

4. The important factor affecting the optical properties of LEDs due to thermal overstress failure has always been temperature. This is because under the premise that the thermal resistance of the LED system remains unchanged, the temperature of the solder joints of the package pins increases, and the junction temperature will also increase accordingly. , which then causes the LED to fail prematurely.
