AL-72RD感應(yīng)開(kāi)關(guān)
感應(yīng)開(kāi)關(guān)是指人體紅外智能感應(yīng)開(kāi)關(guān),是一種當(dāng)有人從紅外感應(yīng)探測(cè)區(qū)域經(jīng)過(guò)而自動(dòng)啟動(dòng)的開(kāi)關(guān)。 人體濾光片增強(qiáng)后聚集到紅外感應(yīng)源上。紅外感應(yīng)源通常采用熱釋電元件,這種元件在接收到人體紅外輻射溫度發(fā)生變化時(shí)就會(huì)失去電荷平衡,向外釋放電荷,后續(xù)電路經(jīng)檢測(cè)處理后就能觸發(fā)開(kāi)關(guān)動(dòng)作。人不離開(kāi)感應(yīng)范圍,開(kāi)關(guān)將持續(xù)接通;人離開(kāi)后或在感應(yīng)區(qū)域內(nèi)長(zhǎng)時(shí)間無(wú)動(dòng)作,開(kāi)關(guān)將自動(dòng)延時(shí)關(guān)閉負(fù)載
