Anonymous users2024-01-24Generally, the electrical parameters of the LED lamp beads used in the lamp are the same, and the dimming principle is only to reduce the power supply voltage to the LED lamp beads to reduce the current, so that the LED lamp beads emit light and dim to reduce the brightness of the lamp. Usually there is no need to configure a special LED to achieve low brightness, if the brightness of the lamp beads is obviously different in the same control state, the dark LED is either the quality or the power supply line is problematic.
Normally, it is because after turning off the light, the charge stored in the capacitor in the ballast is slowly released, so the weak current lights up the L E D and glows.
Reline, cancel several groups, or add segmented controllers, group control.
It is three threads if it is in accordance with the specification. Having roots is the bottom line. There is a bottom line on the downlight and the light strip.
Hard strip light, generally 5730LED lamp beads are welded on the aluminum substrate with SMD technology.
If the relay contacts in the top plate controller of the lighting are damaged, it is recommended to find the merchant for warranty.
