智能外控集成 LED 光源

WS2815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、高精度的內(nèi)部振蕩器和高精度恒流控制模塊，有效保證了像素點(diǎn)光的顏色高度一致。實(shí)現(xiàn)雙路信號(hào)傳輸，在單個(gè)像素點(diǎn)損壞的情況下，不影響整體色彩的顯示。\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來的數(shù)據(jù)，首先送過來的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)過內(nèi)部整形處理電路整形放大后通過DO端口開始轉(zhuǎn)發(fā)輸出給下一個(gè)級(jí)聯(lián)的像素點(diǎn) ● 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● 12V供電電壓，有效降低整個(gè)像素點(diǎn)的工作電流，降低線路板壓降，最大限度保證像素點(diǎn)在很遠(yuǎn)距離傳輸時(shí)\r\n達(dá)到良好的混光一致性。\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)過波形整形再輸出，保證線路波形畸變不會(huì)累加。\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。\r\n● 串行級(jí)聯(lián)接口，能通過一根信號(hào)線完成數(shù)據(jù)的接收與解碼。\r\n● 斷點(diǎn)續(xù)傳，額外增加一路信號(hào)線，實(shí)現(xiàn)雙路信號(hào)傳輸，在單個(gè)像素點(diǎn)損壞的情;
