說到贛州舞臺燈光大(da)家都(dou)是(shi)不陌(mo)生(sheng)的(de)，平常在我們的(de)日(ri)常生(sheng)活(huo)中就能(neng)經常看到，只是(shi)對于它的(de)維護和(he)注意事項我們了解的(de)沒有那(nei)么的(de)清楚，今天就來和(he)大(da)家分享(xiang)一(yi)下關(guan)于舞臺燈光(guang)要注意的(de)點(dian)。

1、 開場前半小(xiao)時，打開所有(you)設備，進行低溫(wen)預熱，同(tong)時檢測所有(you)設備及(ji)線路。低溫(wen)狀(zhuang)態是(shi)指燈光微亮(liang)即(ji)可；

2、 開機預熱(re)十五分鐘后將所有設備(bei)(bei)歸零，讓(rang)設備(bei)(bei)散熱(re)，散熱(re)時間不低(di)于十五分鐘；

3、 散熱后，即(ji)可正式進入音(yin)樂演出階段；

4、 演出(chu)結束、客人離場后(hou)，燈光師應(ying)關閉(bi)所(suo)有(you)所(suo)有(you)設備(bei)(bei)，并(bing)讓設備(bei)(bei)散熱十五至二十分鐘(zhong)，然后(hou)將設備(bei)(bei)進行封存或遮罩，燈光師方可(ke)離場。

舞(wu)臺(tai)燈(deng)(deng)光(guang)音(yin)響(xiang)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)匹配：從(cong)原則上(shang)來(lai)(lai)講，音(yin)箱(xiang)(xiang)(xiang)額定功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)與功(gong)(gong)(gong)(gong)(gong)(gong)放(fang)(fang)額定功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)不(bu)一致時(shi)，舞(wu)臺(tai)燈(deng)(deng)光(guang)音(yin)響(xiang)對(dui)于(yu)功(gong)(gong)(gong)(gong)(gong)(gong)放(fang)(fang)來(lai)(lai)說，它的(de)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)大(da)(da)小只(zhi)與音(yin)箱(xiang)(xiang)(xiang)阻(zu)抗(kang)有(you)關，而與音(yin)箱(xiang)(xiang)(xiang)額定功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)無(wu)關。無(wu)論音(yin)箱(xiang)(xiang)(xiang)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)與功(gong)(gong)(gong)(gong)(gong)(gong)放(fang)(fang)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)是(shi)否相同，對(dui)功(gong)(gong)(gong)(gong)(gong)(gong)放(fang)(fang)工(gong)作(zuo)無(wu)影響(xiang)，只(zhi)是(shi)對(dui)音(yin)箱(xiang)(xiang)(xiang)本(ben)身安全有(you)關。如(ru)果音(yin)箱(xiang)(xiang)(xiang)阻(zu)抗(kang)符合(he)匹配要求，舞(wu)臺(tai)燈(deng)(deng)光(guang)音(yin)響(xiang)而承(cheng)受(shou)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)比功(gong)(gong)(gong)(gong)(gong)(gong)放(fang)(fang)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)小，則推動功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)充(chong)足，聽(ting)起來(lai)(lai)很(hen)舒(shu)服。這(zhe)就是(shi)常(chang)說的(de)功(gong)(gong)(gong)(gong)(gong)(gong)放(fang)(fang)儲備功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)要大(da)(da)，才能充(chong)分(fen)地表(biao)現(xian)(xian)出音(yin)樂(le)全部內涵，尤其是(shi)音(yin)樂(le)中的(de)低頻(pin)部分(fen)，表(biao)現(xian)(xian)更為生動、有(you)力。這(zhe)是(shi)一種較好的(de)匹配。如(ru)果音(yin)箱(xiang)(xiang)(xiang)的(de)額定阻(zu)抗(kang)大(da)(da)于(yu)功(gong)(gong)(gong)(gong)(gong)(gong)放(fang)(fang)的(de)額定功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)，雖然二者都能安全的(de)工(gong)作(zuo)，但這(zhe)時(shi)功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)放(fang)(fang)大(da)(da)器推動功(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)顯得(de)不(bu)夠，舞(wu)臺(tai)燈(deng)(deng)光(guang)音(yin)響(xiang)會覺得(de)響(xiang)度不(bu)足，往往出現(xian)(xian)已經開到飽和狀(zhuang)態，失真加(jia)劇，仍(reng)感到力不(bu)從(cong)心。
