1. WS2813BIt is a set of control circuit and lighting circuit in one of the intelligent external controlLEDlight source. Its shape and a5050LEDSame 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 and12VProgrammable high voltage constant current control section ,Effectively guarantee the color of the pixel spot light uniform height.
2. NRZ data protocol uses a single line of communication, the pixels on the POR,DINReceives data transmitted from the controller over the first sent over24bitAfter the data is first extracted pixel , to the pixel data of the internal latch , the remaining data after the shaping process through the internal circuit is amplified by shapingDOOutput port begins forwarding to the next cascaded pixels , each pixel through a transmission , the signal reduction24bit. Pixel using automatic forwarding shaping technology, making the number of pixels of the cascade unlimited signal transmission , signal transmission speed is only limited .
3. LEDHaving a low-voltage driving , environmentally friendly energy , high brightness, large angle scattering , consistency , low power, long life and other advantages . The control circuit is integrated inLEDAbove, the circuit becomes more simple, small , easy to install even more .
