Can you make a LED light dimmable?

When it comes to LED lighting people often wonder if LED lighting is dimmable. The short answer to this question is: Yes, LED lighting is certainly dimmable!

What is the purpose of LED dimmer circuit?

First, you can use the LED dimmer circuit to control the luminance of the light source. For example, if you want to have illumination that is not too bright, you can dim the LED to the desired level. It is especially applicable in amphitheaters and performance stages where dimming is necessary.

How does a 12v LED dimmer work?

PWM dimming works by sending pulses of current to your LEDS, the time span of each pulse is varied so that you can sufficiently control the current that flows to your LEDs.

Can I use a potentiometer to dim LED lights?

One of the simplest and most affordable solutions to dim with the LED drivers is to use a simple 100k Ohm potentiometer. This is a variable resistor that easily attaches to the dimming wires for a cost-effective solution. See figure 1 for how to hook up a potentiometer to the dimming wires of a Mean Well HLG.

How do you control the brightness of an LED?

To change the brightness by adjusting the resistor value – just add a potentiometer in series with the LED. When you adjust the knob of the resistor, the brightness of the LED will change. Another method is to turn the LED on and off fast.

How do you dim LED with a resistor?

Back to dimming LEDs If you simply reduce the voltage to a resistor-LED series combination, you will dim the LED. The slight hiccup is that the LEDs will not begin to light up until there’s about 1.5 volts across each LED.

What happens if I dim a non dimmable LED?

So what happens if you use non-dimmable LEDs on a dimmer? Well, at best the bulb just won’t dim properly. At worst, though, you might damage the bulb. You see, dimmable LEDs have special circuitry inside that allows them to respond to varying current levels or “pulsing” current waves to produce a dimming effect.

How to design a simple LED circuit?

Simple LED Circuit Diagram.

Finding the Polarity of LED: If you look at the LED carefully you can find one leg of the LED is bigger than another.

Choosing the Resistor Value for LED: Resistor is very important component here,if you connect LED to the Battery without any resistor,then your LED will burn immediately.
