WS2813B is a set of control circuit and lighting circuit in one of the smart external control LED light source. Its shape and a same 5050LED lamp beads, each element is a pixel. Pixels contained within an intelligent digital interface data latch signal shaping amplification drive circuit further includes a high-precision internal oscillator and programmable 12V high-voltage constant current control section, to ensure the effective pixel light color highly consistent.
NRZ data protocol uses a single line of communication, the pixels in POR, DIN terminal receiving the data transmitted from the controller, the first to send over the 24bit pixel data is extracted the first point, to the internal pixels data latch, the remaining data processing circuit through the internal plastic shaping amplified through the DO output port begins forwarding to the next cascaded pixels, each pixel through a transmission, the signal reduction 24bit. Pixel using automatic forwarding shaping technology, making the number of pixels of the cascade unlimited signal transmission, signal transmission speed is only limited.
LED has a low voltage driving, high energy saving and environmental protection, brightness, scattering angle, consistency, low power, long life and other advantages. The control circuit is integrated in the LED above the circuit becomes more simple, small, easy to install even more
