WS2812B is popular last two years,and most of us are using the white face
ws2812b smd leds,
but sometimes we need some more choice for the black finish smd
led,here are the new choice for you,it is the best chioce to match
the black pcb for ws2812b led strips.
Features and Benefits
l Intelligent reverse connect protection, the power supply reverse
connection does not damage the IC.
l The control circuit and the LED share the only power source.
l Control circuit and RGB chip are integrated in a package of 5050
components, form a complete control of pixel point.
l Built-in signal reshaping circuit, after wave reshaping to the
next driver, ensure wave-form distortion not accumulate.
l Built-in electric reset circuit and power lost reset circuit.
l Each pixel of the three primary color can achieve 256 brightness
display, completed 16777216 color full color display, and scan
frequency not less than 400Hz/s.
l Cascading port transmission signal by single line.
l Any two point the distance more than 5m transmission signal
without any increase circuit.
l When the refresh rate is 30fps, cascade number are not less
l Send data at speeds of 800Kbps.
l The color of the light were highly consistent, cost-effective..
l Full-color module, Full color soft lights a lamp strip.
l LED decorative lighting, Indoor/outdoor LED video irregular
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
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.
