The main problems are as follows:
< br >
1.led power driver has problems.
< br >
2. There are problems with LED lamp beads and led power driver.
< br >
3. Virtual connections exist. Solution: 1. The first switch control is the neutral line, if all the lights have this problem, the load line under the main brake is switched, if the individual flash, the flash of the light to the neutral line change, let the switch control the fire line; The other one is the one with a little light on the switch, the one that lights up when you turn it off, just take it off. The quality of the lamp bead is general, if you find that the lamp is not bright, there is no black spot in the drive power supply, you can replace the lamp bead. 2. If there is a problem with the LED lamp constant current, you need to replace the new constant current. Hardware store to buy a suction hook, adsorbed in the ceiling buckle corner, gently pull, you can pull down, you can repair LED lights. 1.LED lamps and incandescent lamps are not the same, incandescent lamps are filament heat generated photons, emitted light warm light, longer wavelength, will not be harmful to the human body. The LED lamp does not have a filament, and the principle of luminescence is to use a blue chip with various colors of phosphor to emit light. 2. The LED emitting blue light can be obtained directly by using the blue light chip, or the blue phosphor that can emit fluorescence can be obtained by using the ultraviolet chip. 3. LED lights emitting green light can be obtained by using ultraviolet chips and green phosphors.

4. LED lights emitting yellow light, ultraviolet chip plus yellow phosphor can be obtained.

5. White LED lights are a little special, mainly using three primary colors for color matching and configured into white light. You can use blue chip green phosphor red phosphor.
1, when installing the ceiling light, pay attention to it, be sure to install it in place, if the neutral line and the fire line are connected to the wrong, it is easy to flash the problem. The lamp must be connected to the fireline, if the neutral line is received, the power is turned off, and the ceiling lamp will not stop flashing.
2, it may be that the lamp and the current through, and some electric lights will produce self-inductive current, in this case we need to replace the ceiling lamp, for example, into an ordinary incandescent lamp, or directly buy a relay, the relay in series to the circuit, you can make the current absorption, no flashing problems.
1, replace the ceiling lamp, such as an ordinary incandescent lamp, or directly buy a relay, the relay in series to the circuit, you can make the current absorption, there will be no flashing problems.
2, if you really can not find out the reason, only can be replaced, and the price of the ceiling lamp is not particularly expensive, you can choose an LED ceiling lamp.
for the following reasons
This may be caused by poor contact of the ceiling light switch. Solution: Replace the ceiling light switch.
It may also be caused by poor contact between the ceiling lamp bulb and the lamp head. Solution: Turn off the ceiling light switch, unscrew the ceiling light bulb, pry out the fire wire spring blade in the middle of the lamp head, and screw on the bulb.
