PULSE WITH MODULATION (PWM)
Pulse Width Modulation (PWM) refers to the concept of rapidly pulsing a digital signal through electrical wiring. PWM provides the ability to ‘simulate’ varying levels of power by oscillating the output from the microcontroller.
Problem: Poor PWM lighting controls create flicker. Flicker can impact your health, mood, and performance throughout the day. Flicker also triggers headaches, migraines, fatigue, epilepsy, and other neurological responses and in general, becomes a distraction.
AWA has created a database of lighting control specifications that can:
- Prevent flickering in the lighting systems
- control the fading in and out of LEDs without any adverse health impact
- Drive LEDs with DC supply to eliminate PWM
