RGB LED lights are made by mixing red, green and blue. The three primary colors are combined to form an image. In addition, there are also blue LEDs with yellow phosphors, and ultraviolet LEDs with RGB phosphors. The colors of some LED backlights are particularly clear and bright, even to the extent of high-definition TVs. This situation is precisely the characteristics of RGB, which advertises the characteristics of red as red, green as green, and blue as blue. In terms of color mixing, it has more diverse characteristics.

What are the applications of RGB LED lights?

Most of the current monitors use the RGB color standard.

On the display, colors are produced by hitting the red, green, and blue light-emitting poles of the screen with an electron gun. Currently, computers can generally display 32-bit colors, and there are more than 10 million colors.

All the colors on the computer screen are made up of the three colors of red, green and blue mixed in different proportions. A set of red, green and blue is the smallest display unit. Any color on the screen can be recorded and expressed by a set of RGB values.


What is the principle of RGB LED lights?

RGB LED lights are designed from the principle of color luminescence. In layman's terms, its color mixing method is like red, green, and blue lights. When their lights overlap each other, the colors are mixed, and the brightness However, it is equal to the sum of the brightness of the two, and the more the mixture is mixed, the higher the brightness is, that is, additive mixing.

For the superposition of red, green and blue lights, the brightest superposition area of the central three colors is white, and the characteristics of additive mixing: the more superposition, the brighter.

The three color channels of red, green, and blue are divided into 256 levels of brightness for each color. At 0, the "light" is the weakest - it is turned off, and at 255, the "light" is the brightest. When the three-color grayscale values are the same, gray tones with different grayscale values are generated, that is, when the three-color grayscale is all 0, it is the darkest black tone; when the three-color grayscale is 255, it is the brightest white tone .


How do RGB LED lights show different colors?

The color of an RGB LED light is called an additive color because you create white by adding R, G, and B together (that is, all the light is reflected back to the eye). Additive colors are used in lighting, television and computer monitors. For example, displays produce color by emitting light from red, green, and blue phosphors. The vast majority of the visible spectrum can be represented as a mixture of red, green, and blue (RGB) light in varying proportions and intensities. When these colors overlap, cyan, magenta, and yellow are produced.


Rainmin also offers its own advanced light control software, LightShow Pro, which can be used with any of the Rainmin RGB controllers to create your own effects or program the lights to music.
