How Does RGB LED Work?

RGB LED is composed of three primary colors, red, green, and blue. Each color is made up of a certain number of sub-colors. For example, the RGB LED is composed of three primary colors: red (R), green (G), and blue (B).

RGB LED technology works by passing an electric current through the LED in a specific sequence. The sequence corresponds to the levels of each color in an RGB LED. When current is passed through the LED in this sequence, it produces light that is composed of those levels of red, green, and blue. You can also opt to RGB LED Lights UK – Color Lighting by LIGMAN.

There are several advantages to using RGB LEDs over traditional incandescent lighting. First and foremost is that RGB LEDs consume far less electricity than traditional incandescent lamps. In fact, an RGB LED consumes only about one-thousandth of the amount of electricity as a traditional incandescent light bulb.

This makes them ideal for use in applications where conservation or cost of energy is critical, such as the lighting in public spaces. In addition to consuming less electricity, RGB LEDs are also more efficient than traditional incandescent lamps, producing light that is up to 80% brighter as measured in lumens per watt.

In general, the brightness of an LED can be controlled by its current and voltage levels. Higher voltage and current levels will produce higher brightness. This can be seen when comparing the lumen output of traditional incandescent lamps versus a typical LED.

The following chart shows this comparison: As expected, the LED produces greater lumen output at lower voltage and current levels.

For example, a 10-Watt halogen lamp (1/12th the value of an incandescent 100-Watt lamp) produces only around 600 lumens. A 10-Watt LED will produce about 1,100 lumens at the same current level. In contrast, a typical incandescent lamp that is rated for 100-Watts but may actually produce up to 200-Watts will produce about 250 lumens at the same voltage and current levels.

The brighter light produced by the LED can be seen in the following chart: The brightness of LEDs also varies depending on their color temperature or color quality. This is because LEDs use red, green, and blue phosphors in their manufacture, which are all different from each other in terms of their spectral output and color temperature.
