The forward voltage of the LED is also determined by its forward current. When the voltage exceeds a certain threshold, the current will rise exponentially, thereby breaking down the LED PN junction. Generally, the reverse characteristic curve changes steeply. That is, the characteristics of the current flowing through the LED PN junction with voltage. ![]() Regarding the LED dimmer switch, we must first understand the volt-ampere characteristics of the LED. Although variable voltage devices can be used for various purposes, this regulation is aimed at controlling lighting. By reducing or increasing the rms voltage, the light output of different intensities produced by the average power lamp is promoted. The purpose of the dimmer is to adjust the different brightness of the light. ![]() LED dimmer switch is an electrical device that changes the luminous flux of the light source in the lighting device and adjusts the illuminance level.
