4-Pin Board WS2812B Rgb Full Color SMD Led chip With Heatsink
IC Introduction
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. 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.

Advantage
LED has the advantages of low voltage drive, environmental
protection and energy saving, high brightness, large scattering
Angle, good consistency, ultra-low power, ultra-long life and so
on.The control circuit is integrated on the LED, making the circuit
more simple, smaller and easier to install.
