說到贛州舞臺燈光大家都(dou)是不陌(mo)生的，平(ping)常(chang)在(zai)我們的日常(chang)生活中(zhong)就能經常(chang)看到，只是對于它(ta)的維(wei)護和(he)注意(yi)事(shi)項我們了解的沒有那(nei)么的清楚，今天就來和(he)大家分享一下關于舞臺燈(deng)光要注意(yi)的點。

1、 開場(chang)前半小時，打(da)開所(suo)(suo)有(you)設(she)備(bei)，進行低溫(wen)預熱，同時檢測(ce)所(suo)(suo)有(you)設(she)備(bei)及線路。低溫(wen)狀態(tai)是指(zhi)燈光微亮即可；

2、 開機預熱十五(wu)分鐘后將所有設備歸(gui)零，讓設備散(san)熱，散(san)熱時間不(bu)低(di)于十五(wu)分鐘；

3、 散(san)熱后，即可正(zheng)式(shi)進入音樂演出階段(duan)；

4、 演出結束(shu)、客人離(li)場后，燈(deng)光(guang)師應(ying)關(guan)閉所有(you)所有(you)設(she)備，并讓設(she)備散熱十五至二十分鐘，然(ran)后將(jiang)設(she)備進行(xing)封存或遮罩，燈(deng)光(guang)師方可離(li)場。

舞(wu)臺(tai)燈光音(yin)(yin)響(xiang)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)匹配：從原則(ze)上來(lai)(lai)講，音(yin)(yin)箱(xiang)額(e)定(ding)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)與(yu)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)放(fang)(fang)(fang)額(e)定(ding)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)不一(yi)致時，舞(wu)臺(tai)燈光音(yin)(yin)響(xiang)對(dui)于功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)放(fang)(fang)(fang)來(lai)(lai)說，它的功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)大(da)小只與(yu)音(yin)(yin)箱(xiang)阻抗有(you)關，而與(yu)音(yin)(yin)箱(xiang)額(e)定(ding)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)無(wu)關。無(wu)論音(yin)(yin)箱(xiang)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)與(yu)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)放(fang)(fang)(fang)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)是(shi)否(fou)相同，對(dui)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)放(fang)(fang)(fang)工(gong)作無(wu)影響(xiang)，只是(shi)對(dui)音(yin)(yin)箱(xiang)本身安全(quan)有(you)關。如果音(yin)(yin)箱(xiang)阻抗符合匹配要求(qiu)，舞(wu)臺(tai)燈光音(yin)(yin)響(xiang)而承受功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)比功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)放(fang)(fang)(fang)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)小，則(ze)推動功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)充足，聽起(qi)來(lai)(lai)很舒服。這就是(shi)常說的功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)放(fang)(fang)(fang)儲備功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)要大(da)，才能充分地表現出(chu)音(yin)(yin)樂(le)(le)全(quan)部內涵，尤其是(shi)音(yin)(yin)樂(le)(le)中(zhong)的低(di)頻部分，表現更(geng)為生動、有(you)力。這是(shi)一(yi)種較好的匹配。如果音(yin)(yin)箱(xiang)的額(e)定(ding)阻抗大(da)于功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)放(fang)(fang)(fang)的額(e)定(ding)功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)，雖然二者(zhe)都能安全(quan)的工(gong)作，但這時功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)放(fang)(fang)(fang)大(da)器推動功(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)(gong)率(lv)(lv)(lv)顯得(de)不夠，舞(wu)臺(tai)燈光音(yin)(yin)響(xiang)會覺得(de)響(xiang)度不足，往(wang)往(wang)出(chu)現已經開到飽和(he)狀態，失真(zhen)加劇(ju)，仍感到力不從心。
