PWMdimning
PWM dimming, or Pulse Width Modulation dimming, is a method used to control the brightness of lighting devices, particularly LEDs, by adjusting the duty cycle of a digital signal. In PWM dimming, the light is rapidly turned on and off at a high frequency, with the ratio of "on" time to the total cycle duration determining the perceived brightness. For example, a 50% duty cycle means the light is on half the time and off half the time, resulting in approximately half brightness.
This technique offers several advantages, including high efficiency and precise control. Since the light source is
PWM dimming is widely used in LED lighting systems, display screens, and electronic circuits. It allows for
However, there are some limitations to PWM dimming. At very low duty cycles, the switching noise can
Overall, PWM dimming remains a popular and effective method for controlling light intensity in various electronic
