    Hello :

    1. The new type of [LED] panel lamp is powered by [high-frequency transformer].

    2. The reason for the failure is the instability of the output voltage of the high-frequency transformer.

    3. Please [replace] the transformer of the same specification, pay attention to the [same specification].

    If the drive is broken, take it off and buy one as it is (the same output current and voltage) and replace it.

    The quality is not good, the fault of the voltage regulator circuit, replace it with a new one, there is no maintenance value.

    You can buy LED light sources and electrical appliances directly on Taobao, and the lamp shell can also be used, which is the most cost-effective.

    The analysis is as follows:

    There are four possible situations that cause the LED light source to flicker or turn on and off

    1. LED lamp beads do not match the LED driving power supply, normal single full 1W lamp beads withstand current: 280-300mA, voltage: if the lamp bead chip is not full power, it will cause the light source strobe phenomenon, the current is too high The lamp beads can not withstand the light on and off, and the serious phenomenon will burn the gold wire or copper wire built in the lamp beads, resulting in the lamp beads not lighting up.

    2. It may be that the drive power supply is broken, as long as it is replaced with another good drive power supply, it will not flash.

    3. If the drive has an over-temperature protection function, and the material heat dissipation performance of the lamp cannot meet the requirements, the over-temperature protection of the drive will also flash and go out, for example: the 20W flood light shell is used to assemble a 30W lamp, and the heat dissipation work is not done well.

    4. If the outdoor lamps also have the phenomenon of strobe on and off, it means that the lamps are flooded. The consequence is that it doesn't light up when it flashes. If the drive is waterproof, it is just a matter of breaking the lamp beads and replacing the light source.
