What Are The Disadvantages Of Pwm (pulse Width Modulation) Dimming?

Answer»

Following are the disadvantages of PWM dimming:

  • Relatively more expensive.
  • Flicker perceived in peripheral vision if the DRIVER is run below 100Hz frequency.
  • Stroboscopic effect evident in FAST MOVING environments when the driver frequency is low.
  • Electromagnetic INTERFERENCE (EMI) ISSUES due to rise and fall of the current in PWM dimming.
  • Performance issues arise when the driver is mounted remotely from the light source.
