智½外控集成

LED

光源

主要特点

● IC控制电路与LED点光源公用一个电源。

● 控制电路与RGB芯片集成在一个5050封装的元器件

中，构成一个完整的外控像素点。

● 内½信号整½电路，

任½一个像素点收到信号后经

过波½整½再输出，保证线路波½畸变不会累加。

● 内½上电复½和掉电复½电路。

● 每个像素点的三基色颜色可实现256级亮度显示，

完成16777216种颜色的全真色½显示，扫描频率

不½于400Hz/s。

● 串行级联接口，

½通过一根信号线完成数据的接收

与解码。

● 任意两点传传输距离在不超过3米时无需增加任½

电路。

● ½刷新速率30帧/秒时，级联数不小于1024点。

● 数据发送速度可达800Kbps。

● 光的颜色高度一致，性价比高。

主要应用领域

● LED全½发光字灯串,LED全½模组， LED全½½灯

条硬灯条,LED护栏管。

● LED点光源，LED像素屏，LED异½屏，各种电子产

品，电器设备跑马灯。

产品概述

WS2812B是一个集控制电路与发光电路于一½的智½外控LED光源。其外型与一个5050LED灯珠相同，每

个元件即为一个像素点。

像素点内部包含了智½数字接口数据锁存信号整½放大驱动电路，还包含有高精度的内

部振荡器和可编程定电流控制部分，有效保证了像素点光的颜色高度一致。

数据协议采用单线½零码的通讯方式，像素点在上电复½以后，DIN端接受从控制器传输过来的数据，首先

送过来的24bit数据被第一个像素点提取后，送到像素点内部的数据锁存器，剩½的数据经过内部整½处理电路

整½放大后通过DO端口开始½发输出给下一个级联的像素点，每经过一个像素点的传输，信号减少24bit。像素

点采用自动整½½发技术，½得该像素点的级联个数不受信号传送的限制，仅仅受限信号传输速度要求。

LED具有½电压驱动，环保节½，亮度高，散射角度大，一致性½，超½功率，超长寿½等优点。将控制电

路集成于LED上面，电路变得更加简单，½积小，安装更加简便。
