智能外控集成 LED 光源

WS2812D-F8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)F8 LED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 ● 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)8mm直徑的圓頭四腳直插封裝的燈珠中，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，掃描頻率不低于\r\n400Hz/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)傳傳輸距離在不超過(guò)2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;
