What is a LED Dimmer Driver? Two Dimming Techniques You Need to Know

Light-emitting diode (LED) lighting is highly customizable. But because LEDs work on direct current, dimming an LED would require the use of LED dimmer drivers, which can function in two ways.

What is a LED Dimmer Driver?

Because LEDs run on low voltage and in direct current, one must control the amount of electricity flowing into an LED by adjusting the LED’s driver.

Both of low voltage and high voltage LED strip needs LED dimmer driver,so popular in Electronic business platform will include LED strips,LED dimmer driver and controller,some will have connectors.So  for dimming led strip,it’s necessary.

Because the LED driver is the one responsible for controlling the electricity that flows into the LED, it is by modifying this device that the LED can be dimmable. This modified LED driver, also known as an LED dimmer driver, adjusts the brightness of the LED.

When in the market for a good LED dimmer driver, it’s important to pay attention to its ease of use. Having a LED dimmer driver with dual in-line package (DIP) switches in front allows users to easily change output current, therefore, adjusting the brightness of the LED.

Not only for dimming led strip,also for RGB RGBW strips,we have pixel driver.Controller also is important,traic,daynamic pixel and CCT.Customer like it small and multifunctional,oh,dont forget the DMX contro also.The most popular scene is KTV，club and Outdoor lighting project,Of course, it is also quite good to adjust the atmosphere at home.

Another feature to look out for is the compatibility of the LED dimmer driver with Triode for Alternating Current (TRIAC) wall plates and power supplies. This ensures you can control the amount of electric current flowing into the LED at high speed, and your dimmer will serve whatever project you have in mind.

Pulse width modulation (PWM) involves shortening the amount of leading current going through the LED.

The current flowing into the LED is the same, but the driver regularly turns the current on and off and on again to regulate the amount of current powering the LED. This really quick exchange results in dimmer lighting, with an imperceptible flicker too quick for the human eye to catch.

Amplitude modulation (AM) involves reducing the electric current flowing into the LED. With less power comes dimmer lighting. Similarly, with lower current comes lower temperature and higher efficacy for the LED. This method also eliminates the risk of flicker.

Do note, however, this method of dimming does risk altering the color output of the LED, especially at low levels.
