WS2812B is an intelligent controlled LED light source where the control circuit and RGB chip are integrated into a 5050 component package. Its internal parts include intelligent digital port data latching and amplification drive signal shaping. It also includes an internal precision oscillator and a 5V voltage programmable constant current control part, effectively ensuring that the light color height of the pixel point is consistent. The data transmission protocol uses a single NZR communication mode. After pixel power-off, the DIN port receives data from the controller, the first pixel collects the initial 24-bit data, and then sends it to the internal data latch, the other data converted by the internal signal conversion amplifier circuit is sent to the next cascade pixel through the DO port. After transmission for each pixel, the signal is reduced to 24 bits. The pixel uses automatic reshaping transmission technology, meaning the pixel cascade count is not limited to signal transmission, depending only on the signal transmission rate. Low drive voltage LED, environmental protection and energy saving, high brightness, wide dispersion angle, good consistency, low power consumption, long lifespan, and other advantages. The control chip integrated into the LED above becomes a simpler circuit, small volume, convenient installation.
