說到贛州舞臺燈光大(da)家都(dou)是不陌生的(de)(de)，平常在我們的(de)(de)日常生活(huo)中就能經(jing)常看到，只是對于它的(de)(de)維護和注意(yi)事項我們了解(jie)的(de)(de)沒有(you)那么(me)的(de)(de)清(qing)楚，今天就來和大(da)家分(fen)享一(yi)下(xia)關(guan)于舞臺燈光(guang)要注意(yi)的(de)(de)點。

1、 開場前半小(xiao)時(shi)，打開所有設備(bei)，進行低(di)溫預熱，同時(shi)檢測所有設備(bei)及線路(lu)。低(di)溫狀態(tai)是指(zhi)燈光微亮即可；

2、 開(kai)機預熱(re)(re)十(shi)五分鐘(zhong)后將所(suo)有設備歸零(ling)，讓設備散(san)熱(re)(re)，散(san)熱(re)(re)時間不低于(yu)十(shi)五分鐘(zhong)；

3、 散熱(re)后，即(ji)可正式進入(ru)音樂演出階段；

4、 演(yan)出結束、客人離場后，燈光(guang)師應關閉所有(you)所有(you)設備(bei)，并讓設備(bei)散(san)熱十五至二十分(fen)鐘(zhong)，然后將(jiang)設備(bei)進行封存或遮罩，燈光(guang)師方可離場。

舞(wu)(wu)臺(tai)燈(deng)光(guang)音(yin)(yin)響(xiang)功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)匹配(pei)：從(cong)原則上來講，音(yin)(yin)箱(xiang)(xiang)額(e)定(ding)功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)與(yu)功(gong)(gong)(gong)(gong)(gong)放(fang)(fang)(fang)額(e)定(ding)功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)不(bu)一(yi)致時，舞(wu)(wu)臺(tai)燈(deng)光(guang)音(yin)(yin)響(xiang)對于(yu)功(gong)(gong)(gong)(gong)(gong)放(fang)(fang)(fang)來說，它(ta)的(de)功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)大小(xiao)只(zhi)與(yu)音(yin)(yin)箱(xiang)(xiang)阻(zu)(zu)抗有關(guan)，而(er)與(yu)音(yin)(yin)箱(xiang)(xiang)額(e)定(ding)功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)無關(guan)。無論音(yin)(yin)箱(xiang)(xiang)功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)與(yu)功(gong)(gong)(gong)(gong)(gong)放(fang)(fang)(fang)功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)是否相(xiang)同，對功(gong)(gong)(gong)(gong)(gong)放(fang)(fang)(fang)工作(zuo)無影響(xiang)，只(zhi)是對音(yin)(yin)箱(xiang)(xiang)本身安全有關(guan)。如果音(yin)(yin)箱(xiang)(xiang)阻(zu)(zu)抗符合匹配(pei)要(yao)求，舞(wu)(wu)臺(tai)燈(deng)光(guang)音(yin)(yin)響(xiang)而(er)承(cheng)受功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)比功(gong)(gong)(gong)(gong)(gong)放(fang)(fang)(fang)功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)小(xiao)，則推動功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)充(chong)足，聽起來很舒(shu)服。這就是常(chang)說的(de)功(gong)(gong)(gong)(gong)(gong)放(fang)(fang)(fang)儲備功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)要(yao)大，才能充(chong)分地(di)表現出音(yin)(yin)樂(le)(le)全部內涵，尤(you)其是音(yin)(yin)樂(le)(le)中的(de)低(di)頻部分，表現更(geng)為生動、有力。這是一(yi)種較好的(de)匹配(pei)。如果音(yin)(yin)箱(xiang)(xiang)的(de)額(e)定(ding)阻(zu)(zu)抗大于(yu)功(gong)(gong)(gong)(gong)(gong)放(fang)(fang)(fang)的(de)額(e)定(ding)功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)，雖然二者都能安全的(de)工作(zuo)，但這時功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)放(fang)(fang)(fang)大器推動功(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)顯得不(bu)夠，舞(wu)(wu)臺(tai)燈(deng)光(guang)音(yin)(yin)響(xiang)會覺得響(xiang)度不(bu)足，往(wang)(wang)往(wang)(wang)出現已經開到(dao)飽(bao)和狀態，失真加劇，仍(reng)感到(dao)力不(bu)從(cong)心(xin)。
