RGB Screen Light consists of two chips of different color with common anode and common cathode connection, so they are scattered pins. When the two chips are illuminated separately, they show two colors, and when the two chips are illuminated together, the colors are mixed, so this is called a three-color LED.

What is the light emission principle of RGB Screen Light?

The terminal voltage of the PN transition in RGB Screen Light represents a certain potential barrier. When the preload is applied in the forward direction, the potential barrier falls and the majority carriers in the P-region and the N-region diffuse to each other. Since the electron mobility is much greater than the hole mobility, a large number of electrons diffuse into the P-range, which represents the injection of minority charge carriers into the P-range. These electrons recombine with holes in the valence band, and the energy obtained during recombination is released in the form of light energy. This is the principle of PN transition light emission.

What is the structure of RGB Screen Light?

RGB Screen Light places three red, green and blue chips in a lamp bead or a PCB or IC in the ordinary two foot lamp bead to control the order and frequency of flashing. Either it is a lamp bead with four feet, one foot is the common cathode or anode of the three chips, and one foot of the other three feet is connected to a chip, and the light is switched on by the current of the three feet controlled or not. Such light can radiate: red, green, blue, red-green, red-blue, green-blue, red-green-blue (i.e. white light), a total of seven colors or four-legged lights. If you want, RGB Screen Light can also control the flow of. The brightness of a particular color is controlled by the flow of different color chips, which leads to a change in the color of the mixed light. In this way, a lamp can theoretically emit an infinite number of colors.

What is the physical principle of RGB Screen Light?

In RGB Screen Light, the three color channels red, green and blue are divided into 256-brightness levels. At 0, the "light" is the weakest–it is off, and at 255, the "light" is the brightest.If the tricolor grayscale values are the same, gray tones with different grayscale values are generated, that is, if the tricolor grayscale is all 0, it is the darkest black tone; if the tricolor grayscale is 255, this is the brightest white tone.

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