可控硅調光器的(de)照(zhao)明系統主(zhu)要采用(yong)(yong)的(de)是(shi)調(diao)(diao)(diao)光(guang)(guang)(guang)器(qi)(qi)，而調(diao)(diao)(diao)光(guang)(guang)(guang)器(qi)(qi)的(de)實(shi)質就是(shi)電(dian)(dian)子(zi)(zi)元(yuan)(yuan)件(jian)(jian)的(de)交(jiao)(jiao)流(liu)(liu)(liu)調(diao)(diao)(diao)壓器(qi)(qi)。在(zai)(zai)(zai)傳(chuan)統的(de)調(diao)(diao)(diao)光(guang)(guang)(guang)器(qi)(qi)使用(yong)(yong)過(guo)程中(zhong)，舊(jiu)式(shi)的(de)變壓器(qi)(qi)和變阻(zu)器(qi)(qi)在(zai)(zai)(zai)調(diao)(diao)(diao)光(guang)(guang)(guang)的(de)過(guo)程中(zhong)給主(zhu)要是(shi)采用(yong)(yong)了調(diao)(diao)(diao)節(jie)(jie)電(dian)(dian)子(zi)(zi)元(yuan)(yuan)件(jian)(jian)內(nei)部的(de)運作的(de)電(dian)(dian)壓、電(dian)(dian)流(liu)(liu)(liu)的(de)運作頻率和幅(fu)度來(lai)實(shi)現(xian)照(zhao)明的(de)調(diao)(diao)(diao)節(jie)(jie)工作。比如說在(zai)(zai)(zai)一(yi)個電(dian)(dian)子(zi)(zi)元(yuan)(yuan)件(jian)(jian)的(de)調(diao)(diao)(diao)光(guang)(guang)(guang)使用(yong)(yong)過(guo)程中(zhong)，一(yi)個在(zai)(zai)(zai)元(yuan)(yuan)件(jian)(jian)內(nei)部的(de)沒有經過(guo)電(dian)(dian)壓器(qi)(qi)進行(xing)調(diao)(diao)(diao)壓的(de)交(jiao)(jiao)流(liu)(liu)(liu)電(dian)(dian)呈(cheng)現(xian)了220V頻率的(de)波形(xing)，在(zai)(zai)(zai)傳(chuan)統的(de)調(diao)(diao)(diao)光(guang)(guang)(guang)器(qi)(qi)的(de)調(diao)(diao)(diao)壓之后的(de)，交(jiao)(jiao)流(liu)(liu)(liu)電(dian)(dian)的(de)電(dian)(dian)壓波形(xing)幅(fu)度變小(xiao)，導致(zhi)這樣(yang)的(de)燈(deng)光(guang)(guang)(guang)變暗。在(zai)(zai)(zai)這種傳(chuan)統的(de)調(diao)(diao)(diao)光(guang)(guang)(guang)模式(shi)中(zhong)，調(diao)(diao)(diao)光(guang)(guang)(guang)器(qi)(qi)雖然在(zai)(zai)(zai)應用(yong)(yong)上(shang)實(shi)現(xian)正弦交(jiao)(jiao)流(liu)(liu)(liu)電(dian)(dian)的(de)幅(fu)值的(de)改變，但是(shi)并沒有真正地實(shi)現(xian)改變電(dian)(dian)流(liu)(liu)(liu)呈(cheng)現(xian)波形(xing)的(de)性質。
