By understanding the nuances of LED dimming, you'll be on your way to creating the perfect ambiance in every room.
Understanding LED Dimming Technology
When it comes to LED dimming, understanding the underlying technology is vital. LED dimming works differently from traditional incandescent bulbs, which simply reduce the voltage to lower light output.
LEDs, however, use a technique called pulse-width modulation (PWM) or constant current reduction (CCR) to achieve dimming effects.
PWM rapidly switches the LED on and off at a high frequency, creating the illusion of dimmed light. The longer the "off" periods, the dimmer the light appears. CCR, on the other hand, reduces the current flowing through the LED, directly lowering its light output.
You'll encounter two main types of LED dimming: leading-edge and trailing-edge. Leading-edge dimmers were designed for incandescent bulbs and may not always be compatible with LEDs.
Trailing-edge dimmers are more suited for LED technology and often provide smoother dimming performance.
