Is It Dangerous When the Light Is Off but Still Glows Slightly?
1 Answers
It is quite common for the light to still glow slightly when turned off. The reasons are as follows: 1. Capacitor step-down current limiting method: The driver of this LED light uses a very simple capacitor step-down current limiting method, rather than a dedicated and standard isolated switching constant current source; 2. Induced electricity: Although the switch is installed on the live wire, the neutral wire is only at 0 potential relative to the live wire and actually may still have a certain voltage, or induced electricity generated by other circuits. Combined with the high luminous efficiency of small-power LED lights; 3. Discharge causing flickering: After the power is turned off, the fluorescence or accumulated induced electricity discharges to a certain extent, resulting in flickering, which is understandable.
