  Product Description:   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.
