The main reason is the failure of filter capacitor

1.what is corn row led lights bead does not match the led driving power supply, normal single foot 1w lamp bead to withstand the current: 280-300ma, voltage: 3.0-3.4v, if the lamp bead chip is not sufficient power, it will cause the light source strobe phenomenon, the current is too high, the lamp bead can not bear a light off, serious phenomenon will burn the gold or copper wire inside the lamp bead, resulting in the lamp bead is not bright.

2 May be the driving power is bad since, as long as the replacement of another good driving power, it will not flash.

3. If the drive has the function of over-temperature protection, and the heat dissipation performance of the lamp material can not meet the requirements, the drive drive over temperature protection will start to work there will be a flicker and off phenomenon, such as: 20w projection lamp shell used to assemble 30w lamps, heat dissipation work is not done.

4. If outdoor lamps and lanterns also have staphyloscopic brightness and extinction, that is, lamps and lanterns are in water. The result is a twinkle and no light. Lamp beads and drive is broken, drive waterproof do good, it is just broken lamp beads, replace the light source.

what is corn row led lights flashing solution:

The occurrence of lights off after flashing, the first to confirm the line problem, the most likely problem, is the switch control of the zero line, this time to correct in time, so as to avoid danger, the correct way is to switch control fire line, zero line connected to the light.

If there are no problems with the circuit, it is possible that what is corn row led lights are generating self-induced current. The easiest way is to buy a 220V relay, the coil and the lamp in series, can be solved.

Note:

what is corn row led lights bead does not match LED drive power supply, normal single foot 1W lamp bead to withstand current: 280-300mA, voltage :3.0-3.4V, if the lamp bead chip is not enough power will be created into the light source staphylling phenomenon, the current is too high lamp bead can not bear a light off, serious phenomenon will be the lamp bead built-in gold wire or copper wire burned off, resulting in lamp bead is not bright.
