How does RGB LED strip work

Before we talk about how an RGB LED strip light works, what is an RGB LED. In the LED light strip industry, the most common RGB LED bead is SMD 5050 RGB LED, which has 3 chips with different colors, red, green, and blue. Various colors light can be obtained through the combination of the light of these three chips. In addition to decorative lighting, RGB LEDs are also applied to display screens, signal lamps, etc.

RGB LED strip light is a lighting fixture in which RGB LEDs are mounted on the felxible or rigid strip PCB, mainly using for decorative lighting. Unlike the PCB of the normal white light LED lamp, the RGB PCB has 3 independent circuits that drive each chip, providing the physical basis for the color changing effect. In order to achieve multicolor lighting effects and dimming also need the external controller, adjusting the current of each circuit.

Multicolor LED strip lights are an irreplaceable part of the decorative lighting market for their colorful lighting effect and adjustability. Although the RGB strip lights have a good performance, they still can not completely replace the white light LED lights. Compare with color changing LED strips, white light LED strips have lower prices, higher brightness, and uniform white light effect.
