WS2812E

智能外控集成 LED 光源; ● IC控制电路与LED点光源共用一个电源。\r\n● 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。\r\n● 内置信号整形电路，任何一个像素点收到信号后经过波形整形再输出，保证线路波形畸变不会累加。\r\n● 内置上电复位和掉电复位电路。\r\n● 每个像素点的三基色颜色可实现256级亮度显示，完成16777216种颜色的全真色彩显示。\r\n● 端口扫描频率2KHz/s。\r\n● 串行级联接口，能通过一根信号线完成数据的接收与解码。\r\n● 任意两点传输距离在不超过5米时无需增加任何电路。\r\n● 当刷新速率30帧/秒时，级联数不小于1024点。\r\n● 数据发送速度可达800Kbps。\r\n● 光的颜色高度一致，性价比高。;

WS2812B是一个集控制电路与发光电路于一体的智能外控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能数字接口数据锁存信号整形放大驱动电路，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。\r\n\r\n 数据协议采用单线归零码的通讯方式，像素点在上电复位以后，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，剩余的数据经过内部整形处理电路整 形放大后通过DO端口开始转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 采用自动整形转发技术，使得该像素点的级联个数不受信号传送的限制，仅受限信号传输速度要求。 高达 2KHz 的端口扫描频率，在高清摄像头的捕捉下都不会出现闪烁现象，非常适合高速移动产品的使用。\r\n\r\n 280μs以上的RESET时间，出现中断也不会引起误复位，可以支持更低频率、价格便宜的MCU。 LED具有低电压驱动、环保节能、亮度高、散射角度大、一致性好超、低功率及超长寿命等优点。将控制电路集成于LED上面，电路变得更加简单，体积小，安装更加简便。
