You have probably come across LEDs (Light-Emitting Diodes)<\/a> of varying brightness intensity. This feature is unique to LEDs. The main upside of using a LED<\/a> is that you can easily change its brightness intensity. You can choose to make it brighter or dimmer depending on your preferences. You can also dim a bunch of LEDs that are in the same circuit. Nonetheless, you must primarily understand how a led dimmer circuit operates.<\/p>\n\n\n\n

If you would like to know how this works, read on.<\/p>\n\n\n

The fundamental LED dimmer circuit working principle is that LEDs are current-driven devices. It implies that their brightness intensity depends on the current that passes through them.<\/p>\n\n\n\n

You only need a simple circuit to control the LED brightness level. For example, most simple LED dimmer circuits to consist of a resistor connected in series with the LED. It is one of the ways of dimming the LED.<\/p>\n\n\n\n

You can also use a microcontroller<\/a> such as Arduino or PICAXE. You can use this method when you want to dim a LED straightforwardly. A microcontroller such as Arduino does not require you to create a circuit from scratch.<\/p>\n\n\n

What is the Purpose of the LED Dimmer Circuit?<\/h2>\n\n

There are several key purposes of a 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.<\/p>\n\n\n\n

You can also use a LED dimmer circuit to control the energy consumption of the system. When you dim a LED, you are controlling the amount of current that it is using. As a result, you save energy.<\/p>\n\n\n
