WS2813B is a set of control circuit and light-emitting circuit in one intelligent external control LED light source. Its appearance and a 5050LED lamp beads the same, each component is a pixel. The pixel contains intelligent digital interface data latch signal shaping amplifier driver circuit, also includes a high-precision internal oscillator and 12V high-voltage programmable current control section, effectively ensure the color of the pixel light of the same height.
Data protocol using single-line return to zero code communication, pixel reset after power-on, DIN side to accept the data transmitted from the controller, first sent over 24bit data is extracted by the first pixel, sent to the internal pixel Data latches, the remaining data through the internal plastic processing circuit plastic amplification amplified through the DO port output forwarded to the next cascade of pixels, each passing a pixel transmission, the signal is reduced by 24bit. Pixels using auto-shaping forwarding technology, making the number of pixels cascaded from signal transmission restrictions, only the limited signal transmission speed requirements.
LED with low-voltage drive, environmental protection and energy saving, high brightness, scattering angle, consistency, low power, long life and so on. The control circuit integrated in the LED above, the circuit has become more simple, small size, easier to install.
