Definitions

  • Dimming is also a concern for white LED emitters, since standard TRIAC -based dimming schemes applicable to incandescent lamps are not directly applicable to LEDs. LED dimming is typically done through pulse width modulation (PWM), rather than TRIAC -based dimming (which delays turning on energy to a bulb following every zero crossing of an AC power source).
  • PWM pulse width modulation
  • TRIAC -based dimming which delays turning on energy to a bulb following every zero crossing of an AC power source.
  • a driver circuit such as the National Semiconductor LM3445
  • Such driver circuitry is also desirably implemented with components mounted to a PCB.
