吊扇燈接線圖 遙控吊扇燈光控制電路圖

如圖是一(yi)種豪華吊扇(shan)(shan)（吊燈）調光(guang)、調速遙控(kong)電路(lu)。此電路(lu)可(ke)以開啟燈光(guang)，并(bing)實(shi)(shi)施(shi)無級調光(guang)、且亮(liang)度(du)可(ke)以記(ji)憶。開啟風(feng)扇(shan)(shan)（吊扇(shan)(shan)），并(bing)可(ke)以分高(gao)、中、低三擋(dang)調速，實(shi)(shi)施(shi)風(feng)扇(shan)(shan)的(de)正轉和反轉。其稍加改動后還可(ke)以控(kong)制窗(chuang)簾的(de)啟閉及音響室背景燈的(de)亮(liang)度(du)，配有(you)遙控(kong)手(shou)機，使用非常方便。

電(dian)(dian)(dian)路(lu)原理(li)：遙控發射(she)(she)器(qi)(qi)(qi)電(dian)(dian)(dian)路(lu)如(ru)圖所示，它使(shi)用(yong)三菱公司的(de)錄像(xiang)機、電(dian)(dian)(dian)視(shi)機上(shang)專(zhuan)用(yong)的(de)30功能紅(hong)外線遙控發射(she)(she)專(zhuan)用(yong)大規模集(ji)成(cheng)電(dian)(dian)(dian)路(lu)M50110BP，其內部由鍵(jian)盤輸入編碼器(qi)(qi)(qi)、指令譯碼器(qi)(qi)(qi)、振蕩(dang)器(qi)(qi)(qi)、定時(shi)信(xin)號發生(sheng)器(qi)(qi)(qi)、掃描信(xin)號發生(sheng)器(qi)(qi)(qi)、編碼調制和(he)輸出緩沖器(qi)(qi)(qi)等部分組(zu)成(cheng)。此(ci)芯片(pian)使(shi)用(yong)3V低壓供電(dian)(dian)(dian)，且振蕩(dang)器(qi)(qi)(qi)在(zai)未(wei)按(an)下任(ren)何鍵(jian)之前不起振，可以(yi)節省用(yong)電(dian)(dian)(dian)。本電(dian)(dian)(dian)路(lu)有5X6鍵(jian)盤矩陣，共發射(she)(she)30條指令。
