General description
WS2812B
is a intelligent control LED light source that the control circuit and
RGB chip are integrated in a package of 5050 components. It internal
include intelligent digital
port
data latch and signal reshaping amplification drive circuit. Also
include a precision internal oscillator and a 12V voltage programmable
constant curre-nt control part,
effectively ensuring the pixel point light color height consistent.
The
data transfer protocol use single NZR communication mode. After the
pixel power-on reset, the DIN port receive data from controller, the
first pixel collect initial 24bit
data
then sent to the internal data latch, the other data which reshaping
by the internal signal reshaping amplification circuit sent to the next
cascade pixel through the DO
port.
After transmission for each pixel?the signal to reduce 24bit. pixel
adopt auto resha-ping transmit technology, making the pixel cascade
number is not limited the signal
transmission, only depend on the speed of signal transmission.
LED with low driving voltage, environmental protection and energy
saving, high brightness, scattering angle is large, good consistency,
low power, long life and other
advantages. The control chip integrated in LED above becoming more simple circuit, small volume, convenient installation.
