Design Description
The top light and location of the stage lighting position form a light distribution array, and each part of the stage has a light distribution point to eliminate dead zones and can be combined flexibly on demand.
Top light system design configuration
The function of the top light is to illuminate the performance space in the depth of the stage. The various lamps used in the top light configuration greatly improve the light transmittance, and can be used for stage top lighting or dyeing.
The distribution of configuration lamps is as follows:
Above the stage, there are a total of 20 ceiling light booms. Each top light uses a different number of lamps
- Arrangement and projection method of lamps:
The first top light and the surface light connect to illuminate the main performance area. Pay attention to the height of the characters when connecting. The first top light can be used as a fixed-point light and special effect lights, and some lights can be selected to enhance the lighting of the fulcrum of the performance area; The road to the tenth road can be projected directly behind the stage, or projected vertically downward, which can enhance the lighting of the stage characters and the scenery space. The front and rear rows of lights are connected to make the stage performance area obtain a more uniform color and brightness.
- Scanner design configuration
The computer lights are mainly arranged on the overhead light pole above the stage, and the projection angle, brightness, changing pattern, beam size, color and other functions of the lights can be adjusted arbitrarily to ensure that the performance of the computer lights change requirements.
- Design configuration of light color changer
The color changer installed on part of the lamps plays a role in stage lighting, dyeing, color change, and setting off the plot to achieve colorful effects.
Stage lighting design process
Light
Multi-point lighting and three-dimensional lighting are used at the same time to meet the lighting needs of different performances on the stage. Surface lighting, top lighting, side lighting, backlighting, slap lighting, and flowing light are set.
1) Make two stage face lights directly in front of the stage, which are used as the main light of the stage. The face lights are mainly used to meet the characters’ need to face the light and highlight the character’s expressions, and more vividly outline the performance characteristics of the actors. Because the surface light is far away from the stage, the surface light uses 16 2KW spotlights and 20 2KW return lights produced by our factory; the spotlight has a long projection distance and strong light; the return light has a wide projection angle and a large spot suitable for large areas. The light improves the stage illuminance; and a surface light color changer is installed to change the color of the light to highlight the stage plot scene.
2) Make two overhead lights above the stage to illuminate the top of the characters and part of the scenery. Choose 12 2KW spotlights and 12 2KW soft lights. The spotlight lighting effect is strong to highlight the characteristics of people and objects; the soft light lighting softly restores the essential colors of people and objects; at the same time, coupled with the application of grouping changes in the dimmer, it can produce different lighting effects.
3) The side lights are located on both sides of the stage and are used to depict and suppress the dark shadow areas of the left and right outlines of people and objects. 6 2KW spotlights and 6 2KW return lights are selected. Use the strong spot of the spotlight and the return light to make the outline more prominent and delicate.
4) Two backlights are set behind the top light. A total of 24 1KW PAR beam lights (bottle lights) and 8 2KW return lights are selected to use their strong light to highlight the overall contours of people and objects.
5) In order to make up for the dark side caused by the lack of face light, top light, side light and backlighting to the contours of characters and objects, and to improve the clarity, slap and flowing light are set on the stage. The distance between the slap and the stage is far away. 6 sets of 2KW spotlights and 6 sets of 2KW return lights are selected for about; 8 sets of 2KW return lights are used for mobile light, equipped with mobile brackets that are randomly placed on the left and right sides of the stage to supplement the lighting of each light. In place.
6) In order to reproduce the stage performance truly, stage background lights are set up, and 8 sets of 1250W sky curtain lights and 8 sets of 1250W ground row lights are selected to achieve a uniform background lighting effect.
7) In order to avoid the dull and unremarkable stage performances, some lamps are equipped with professional color changers, and the timely use of the lighting console grouping will make the performance achieve the remarkable effect of both reality and fantasy.
The above lighting system configuration refers to the relevant national industry standards such as JGJ57-2000, GB/14076-93, GYJ45-92, GBTXXX, GB500116-98.
Hanging Machinery
According to the drawings provided by you, combined with the lighting system, and according to the actual construction situation of your building, the configuration of the hanging equipment is designed as follows:
1) Conference pole 1: Set on the inner side of the platform, used to display the conference slogan and highlight the theme of the conference (it can also play a role in preventing the audience from entering the field of vision over the stage).
2) Stage curtain 1: Located behind the monogram, the curtain has the form of uniform telescoping, stepless speed regulation split, uniform speed split, butterfly curtain, etc. We have chosen the uniform speed split for you The big curtain system; the big curtain is the gateway to the stage and one of the main curtain facilities on the stage. It is mainly used for the opening and closing of the beginning and end of the performance, and is sometimes used as a scene.

5) 5 stage lighting poles: the lighting poles are used to install stage lamps to meet the replacement of lamps during different performances, saving time and effort, and convenient and quick. On the stage, there are 2 top polished poles, 2 backlight poles, and 1 background light pole.
6) Stage side light is very important in stage lighting. Its position is installed in the side light frame and above the left and right sides of the stage.
7) 3 side curtain rods and 3 side curtain rods: used to hang the side curtains. The side curtains are curtains on both sides of the stage. They play a role in covering the audience’s sight on both sides of the stage. The aesthetic design also enhances the audience’s three-dimensional sense of the stage. The curtain is the proscenium of the upper edge of the stage, blocking the audience’s view of the sky above the stage, thus setting off the beauty of the stage.
8) 14 scene bars: the scene bars are used to hang the scene curtain, which is the necessary mechanical equipment (props) for the stage performance. The reasonable use according to the specific situation will make the performance present a vivid effect.
The configuration of the above hanging system is based on: JGJ57-2000, GB/14076-93, GYJ45-92, GBTXXX, GB500116-98, SJ2112XX and other relevant national industry standards.
