智能外控集成 LED 光源; ● IC控制電路與LED點(diǎn)光源共用一個(gè)電源。\r\n● 控制電路與RGB芯片集成在一個(gè)5050封裝的元器件中，構(gòu)成一個(gè)完整的外控像素點(diǎn)。\r\n● 內(nèi)置信號(hào)整形電路，任何一個(gè)像素點(diǎn)收到信號(hào)后經(jīng)過(guò)波形整形再輸出，保證線路波形畸變不會(huì)累加。\r\n● 內(nèi)置上電復(fù)位和掉電復(fù)位電路。\r\n● 每個(gè)像素點(diǎn)的三基色顏色可實(shí)現(xiàn)256級(jí)亮度顯示，完成16777216種顏色的全真色彩顯示。\r\n● 端口掃描頻率2KHz/s。\r\n● 串行級(jí)聯(lián)接口，能通過(guò)一根信號(hào)線完成數(shù)據(jù)的接收與解碼。\r\n● 任意兩點(diǎn)傳輸距離在不超過(guò)5米時(shí)無(wú)需增加任何電路。\r\n● 當(dāng)刷新速率30幀/秒時(shí)，級(jí)聯(lián)數(shù)不小于1024點(diǎn)。\r\n● 數(shù)據(jù)發(fā)送速度可達(dá)800Kbps。\r\n● 光的顏色高度一致，性價(jià)比高。;

WS2812B是一個(gè)集控制電路與發(fā)光電路于一體的智能外控LED光源。其外型與一個(gè)5050LED燈珠相同，每個(gè) 元件即為一個(gè)像素點(diǎn)。像素點(diǎn)內(nèi)部包含了智能數(shù)字接口數(shù)據(jù)鎖存信號(hào)整形放大驅(qū)動(dòng)電路，還包含有高精度的內(nèi)部 振蕩器和可編程定電流控制部分，有效保證了像素點(diǎn)光的顏色高度一致。\r\n\r\n 數(shù)據(jù)協(xié)議采用單線歸零碼的通訊方式，像素點(diǎn)在上電復(fù)位以后，DIN端接受從控制器傳輸過(guò)來(lái)的數(shù)據(jù)，首先 送過(guò)來(lái)的24bit數(shù)據(jù)被第一個(gè)像素點(diǎn)提取后，送到像素點(diǎn)內(nèi)部的數(shù)據(jù)鎖存器，剩余的數(shù)據(jù)經(jīng)過(guò)內(nèi)部整形處理電路整 形放大后通過(guò)DO端口開(kāi)始轉(zhuǎn)發(fā)輸出給下一個(gè)級(jí)聯(lián)的像素點(diǎn)，每經(jīng)過(guò)一個(gè)像素點(diǎn)的傳輸，信號(hào)減少24bit。像素點(diǎn) 采用自動(dòng)整形轉(zhuǎn)發(fā)技術(shù)，使得該像素點(diǎn)的級(jí)聯(lián)個(gè)數(shù)不受信號(hào)傳送的限制，僅受限信號(hào)傳輸速度要求。 高達(dá) 2KHz 的端口掃描頻率，在高清攝像頭的捕捉下都不會(huì)出現(xiàn)閃爍現(xiàn)象，非常適合高速移動(dòng)產(chǎn)品的使用。\r\n\r\n 280μs以上的RESET時(shí)間，出現(xiàn)中斷也不會(huì)引起誤復(fù)位，可以支持更低頻率、價(jià)格便宜的MCU。 LED具有低電壓驅(qū)動(dòng)、環(huán)保節(jié)能、亮度高、散射角度大、一致性好超、低功率及超長(zhǎng)壽命等優(yōu)點(diǎn)。將控制電路集成于LED上面，電路變得更加簡(jiǎn)單，體積小，安裝更加簡(jiǎn)便。
