在專門舞臺燈光調試過程中,常會遇到燈光鋪設不均勻、舞臺燈光噪音過大、面光刺眼等問題,現結合
山東舞臺燈光廠家多年經驗,把經常遇到的問題做了匯總并提供常規的解決辦法:
In the process of debugging special stage lighting, we often encounter problems such as uneven lighting laying, excessive noise of stage lighting, and dazzling surface light. Based on years of experience of Shandong stage lighting manufacturers, we summarize the problems we often encounter and provide conventional solutions:
1、燈光鋪設不均
1. Uneven lighting
在舞臺布光時,燈具數量明明很多,布置的燈光總有陰影區,鋪設不均勻。主要有三種起因:一,燈排數過少燈具擺放分布不均勻;二燈具光束角度過小;三,燈具位置過低。
During stage lighting, the number of lamps and lanterns is obviously large, and the lighting arrangement always has a shadow area, which is uneven. There are three main causes: first, the number of lamp rows is too small, and the lamps are unevenly placed; 2 The beam angle of the lamp is too small; 3、 The lamp position is too low.
1、在設計時要明確清楚舞臺尺寸及舞臺上方燈具可擺放位置的高度;
1. During the design, the size of the stage and the height at which the lamps can be placed above the stage shall be clearly defined;
2、根據舞臺照度及效果需求,選擇合適的光束角度的燈具;
2. According to the requirements of stage illumination and effect, choose the lamps with appropriate beam angle;
3、根據舞臺的高度及燈具光束角度距離,計算燈具之間的距離與數量;
3. Calculate the distance and number of lamps according to the height of the stage and the beam angle distance of lamps;
4、后:確實沒法改變燈具位置和光束角度,交叉調節各個燈排上燈具的投射角度,也可達到目的。
4. Rear: It is really impossible to change the lamp position and beam angle, and cross adjust the projection angle of lamps on each lamp row, which can also achieve the goal.
2、舞臺燈光噪音過大
2. Excessive noise of stage lighting
在舞臺燈光系統搭建完畢后,只要開啟燈光,噪音過大。主要原因:舞臺燈光功率高在使用時會產生大量的熱量,燈具通過風扇散熱產生噪音。燈具可安裝位置太低,周邊沒有做吸聲處理,這個問題更加突出。
After the stage lighting system is set up, as long as the lights are turned on, the noise is too loud. Main reasons: The high power of stage lighting will generate a lot of heat when in use, and the lamps will generate noise through fan heat dissipation. The installation position of the lamp is too low, and the surrounding area has not been provided with sound absorption treatment. This problem is more prominent.
1、在舞臺燈光設計的時候,應當結合項目實際情況:如舞臺上方空間矮、使用場景以話劇等對噪音要求比較高的需求時,應當選擇無需風扇散熱的靜音燈具、燈位布置盡量遠離舞臺輻射區等,可以有效降低舞臺燈光帶來的噪音;
1. In the stage lighting design, the actual situation of the project should be taken into consideration: for example, when the space above the stage is low, and the use scene is high in noise requirements, silent lamps without fan cooling should be selected, and the lamp position should be arranged as far away from the stage radiation area as possible, which can effectively reduce the noise caused by stage lighting;
2、無法更換靜音燈具,燈具安裝位置盡可能提高,燈具周邊做吸聲處理。
2. Silent lamps cannot be replaced, the installation position of lamps shall be improved as much as possible, and sound absorption treatment shall be conducted around the lamps.
3、面光刺眼
3. The face light is dazzling
面光布置不當,容易出現刺眼問題。問題原因在于面光需要保證舞臺具有足夠的覆蓋,距離舞臺較遠,高度一定的話,投射角度不夠,導致射眼睛。
Improper arrangement of surface finish may cause dazzling problems. The reason for the problem is that the surface light needs to ensure that the stage has enough coverage. If it is far from the stage and has a certain height, the projection angle is not enough, causing eye shooting.
面光燈具數量盡可能的多,保證面光覆蓋;面光投射方向與水平方向具有45度夾角即可,角度過小容易刺眼,角度過大臉部下方具有陰影區。
The number of surface light fixtures shall be as large as possible to ensure surface light coverage; The angle between the surface light projection direction and the horizontal direction is 45 degrees. If the angle is too small, it is easy to be dazzling. If the angle is too large, there is a shadow area under the face.
The general solution to the problems in the stage lighting debugging process is from three aspects. If you have any needs or questions, please come to our website http://www.zkvd.cn Look at the information!
