for the following reasons
1. The power cable is in poor contact.
2. The constant current IC of the driver power supply is faulty.
3, the internal electrolyte of the filter capacitor dries up, and the filtering capacity decreases. Just follow these steps to get back to normal. 1. Open the suspended ceiling and reconnect the power cable. 2, replace the same type of constant current drive power supply or filter capacitor! led constant current drive power supply is to convert the power supply into a specific voltage current to drive LED light voltage converter, under normal circumstances: LED drive power input includes high voltage frequency AC (i.e. mains), low voltage DC, high voltage DC, low voltage high frequency AC (such as electronic transformer output). The output of the LED driver power supply is mostly a constant current source that can change the voltage with the change of the LED forward voltage drop value. A. The output current of the constant current drive circuit is constant, and the output DC voltage changes within a certain range with the different size of the load resistance, the load resistance is small, the output voltage is low, the greater the load resistance, the higher the output voltage. b, constant current circuit is not afraid of load short circuit, but it is strictly prohibited to completely open the load. c, constant current drive circuit drive LED is more ideal, but relatively high price. d, should pay attention to the use of the maximum withstand current and voltage value, which limits the number of LED use.
Integrated light flashing failure may have a variety of reasons, such as power supply voltage instability, lamp life expiration, line failure, etc. Here are some solutions:
< br >
Check whether the power supply voltage is stable. If it is unstable, repair or replace the power supply.
< br >
Check whether the lamp has expired. If so, replace the lamp.
< br >
Check whether the circuit is faulty, such as short circuit or open circuit, and repair or replace the circuit.
< br >
Check whether the lamp has poor contact or fixing problems, need to repair or re-fix the lamp.
< br >
If the above problems are eliminated, the integrated light controller may be faulty, and the controller needs to be repaired or replaced.
The following table describes how to rectify the blinking fault of the integrated indicator
1. Check the power connection: Ensure that the power connection of the integrated lamp is firm, and there is no loose or poor contact
2. Replace the bulb: If the integrated lamp uses a replaceable bulb, try replacing the new bulb to make sure it is compatible with the lamp holder and works properly
3. Check the switch or dimmer: If the integrated light is controlled by a switch or dimmer, check whether it works properly. Damaged switches or dimmers may need to be replaced
4. Check the circuit connection: Check the circuit connection of the integrated lamp, including the line and plug, to ensure that they are not damaged or poor contact
5. Check voltage stability: Use a voltage tester to check the stability of the power supply voltage to ensure that the voltage is within the normal range.

When the integrated ceiling light keeps flashing, we must first find the reason. It is possible that the power supply wire contact is loose, and the ceiling needs to be opened. Check again if the power cord is loose and replace it. In addition, there may be a problem with the drive power supply, and you must choose the same model to replace it.

There is also the current voltage is unstable, in this case will also lead to a flickering problem, can only wait until the voltage is normal, can avoid a flickering. It can also be allowed by the power supply bureau to install a voltage regulator in the circuit equipment in the home, which can ensure that the voltage is stable and will not affect the lamps in the home.
