What is RGB Lighting?

What is RGB Lighting?

RGB lighting is a common term in lighting systems. Regardless if you’re in the field of technology, construction, or entertainment, it is a common recommendation because of the huge number of lighting opportunities is offers.

What is RGB Lighting?

Simply put, RGB stands for the primary colors red, green, and blue. When applied to lighting, it produces a vibrant color system that can be mixed in different proportions to achieve almost any kind of color in the spectrum.

The red, green, and blue lights can range from 0 to 100% in terms of intensity. These three colors are blended together by RGB LED products to be able to create more than 16 million shades of light.

However, not every color is possible. Colors like brown and pink are not easy, or even impossible, to achieve.

To further understand the RGB system of colors, there must be a better understanding of light first. Light is made up of energy waves, which when combined are called spectrum. The different lights that we see are composed of diverse colors. At the end of every spectrum, there is a short wavelength, and that is the color blue. On the other end of the spectrum is one more wavelength, which is the color red. The other lights that we see in the spectrum are between red and blue.

What are the Uses of the RGB Lighting System?

The RGB lighting system is what gives LED lights the ability to produce many different colors, but that depends on the angle of the wavelength of the spectrum. That is the primary reason why LED lights are very useful in the production of multi-colored lights. These lights can be used in the entertainment industry, as well as in different other occasions.

This lighting system is already being used in smartphones, where the same light is able to change its color depending on the user’s actions or the situation that is taking place. For example, when a smartphone’s battery is already getting low, its light becomes amber, which indicates that its battery level is below normal. When the smartphone’s battery is already on critical level, the light will change to red. Once the battery is fully charged, the light will then become green.

LED lights, with the application of RGB lighting, are transforming the way lighting applications are used across many different hi-tech industries. As a matter of fact, the lighting application is not just used on our smartphones, but on different vehicles as well. It can be used on any gadget or equipment regardless of the size.

The Additive Color System

The additive color system is created by blending various light colors. Mixing two primary colors results in a lighter color; whereas when mixing the three primary colors, which are red, green and blue, the result would be white light.

The additive color system can be seen on televisions and computer screens. When you try to use a clear magnifying glass, you can see that every pixel is made up of a red, green, and blue sub-pixel. Playing with the brightness of these sub pixels will let you create colors in lights.

What is shown in the table below is the mixing scheme of the additive color system.

Three Types of RGB LED Strips


This is a LED strip that has four diodes with red, green, blue, and white on one diode. This type of LED stripe delivers fine and evenly distributed lighting in any color.


This is a type of LED strip that has three diodes with red, green, and blue on one diode. It has a separate white diode intended for pure white light. An evenly distributed light is not assured because of the greater distance in the middle of the two diodes of the same color. The dissimilarity between the different light beams will not be difficult to see with this type of RGB LED strip.

Classic RGB

This type of LED strip has three diodes with red, green, and blue on one diode. These three diodes are used all at the same time to produce white light. However, the white light may perhaps contain traces of other colors. Also, this white light will not be able to have the equal brightness of the white light from a true white LED.

Because of RGB lighting, most perceivable colors can be created by way of blending different amounts of the three primary colors. This process makes it possible to produce exact and vibrant colors.
