When the LED chandelier light strip in the living room is turned on alone, it flickers on and off, a

Obviously, it is current induction, the live wire in the switch of your LED spotlight is connected with the live wire of the other two switches, and the zero line is connected, if the LED spotlight switch is only the on/off of the zero line of the control, this induced current will be more obvious, and the LED will be slightly bright; If the control is the on-off of the live wire, the induced current will be very small, generally will not cause LED light, if it is still bright, two reasons: 1 is that there is a problem with the design of your LED spotlight power supply controller (this is more esoteric, I don't understand it very well, mainly when the zero live wire has an access circuit, that is, the switch only controls the on-off of one line, but the whole circuit is still disconnected) 2, it is the wiring of the other two ways in your home that happens to be with the line of the LED spotlight, Roughly in the same direction or side by side, winding, so that the induced current will be generated. In general, your LED spotlight controller is too simple.

Answer: There are many types of LED lights, and the situation of LED lights in the living room you said is estimated to be several: 1. The LED lamp itself is caused by the driving power supply of the LED lamp is mostly a switching power supply, and the driver is generally composed of a driver IC inside, and the self-protection of the IC will be considered when the IC is designed in general, automatic protection when the current is too large, automatic protection when the temperature is too high, self-protection when the instantaneous voltage changes too much, or the electrolytic capacitor aging ...... of the driving power supplyWait a minute! The problem in your living room, according to the current LED lamp problem, may be that the temperature of the lamp is too high, resulting in, because, the LED lamp has a characteristic, when the temperature of the LED lamp bead is too high, the VF value (driving voltage) of the LED chip will rise accordingly, the current LED lamps and lanterns are more than a certain number of LED lamps and lanterns in string and form a circuit structure, when the VF value of the LED lamp beads rises, the protection of the switching power supply is triggered, resulting in the LED lamp suddenly "extinguished"; It may also be caused by the aging of the driven electrolytic capacitor; 2. Caused by poor contact of the switch in your living room.
