The Science of LED Flickering

LED lights flicker when dimmed primarily due to mismatches in the electrical supply and control mechanisms. Unlike incandescent bulbs that dim by simply lowering the voltage, LEDs require a constant current to operate efficiently. Dimming is achieved by rapidly switching the LED on and off, a process not visible to the human eye when done correctly.

However, if the frequency of this switching is too low, or if there is instability in the current supply, it results in visible flickering.

Power Supply Compatibility:

The power supply plays a crucial role in maintaining a steady current to the LEDs. An incompatible or low-quality power supply can introduce fluctuations in the voltage, leading to flickering, especially when combined with dimming. It’s essential to use a power supply that matches the voltage requirements of your LED strips and can handle the dimming process without destabilizing the current.

Dimmer Compatibility:

Not all dimmers are created equal, and using one that’s not specifically designed for LED technology can cause flickering. LED-compatible dimmers often use Pulse Width Modulation (PWM) to achieve smooth dimming, turning the LEDs on and off at a frequency high enough to appear as a continuous light to the human eye.

Ensuring your dimmer switch is compatible with your LED strips is key to eliminating flicker, as it provides the precise control needed to maintain a constant current even when dimming.

By understanding and addressing these two critical factors—power supply and dimmer compatibility—you can significantly reduce or eliminate flickering in your dimmable LED strip lights, paving the way for a more stable and pleasant lighting environment.
