There are a variety of stages in the theater, including ordinary framed stage, extended stage, island stage, and stage called black box. Because the stage forms are different, the configuration requirements of the stage lighting are also different. . For the sake of convenience, I take the ordinary mirror-framed stage as an example. This kind of stage has been more in the past or in the reconstruction and newly built theaters. Therefore, it is extremely necessary and necessary to talk about the lighting configuration of this stage.
 　The stage (refers to the framed stage, the same in the following text) will have different lighting requirements due to the different repertoires being performed. Therefore, we must know what kind of repertoire is the main performance on this stage before equipping the lamps, so that the configuration of the lamps will have clearer goals and intentions. If some stage is positioned to perform traditional operas and ballets, the configuration of lamps must be configured according to the requirements of operas and ballets. If special programs such as large-scale singing and dancing, miscellaneous and other special programs are the main ones, in addition to the basic requirements of beam lights and pattern lights, special lighting positions and lighting configurations should be added according to the specific program requirements, so it is more difficult to describe here.

     Therefore, I will only talk about the basic lighting configuration of the theater stage. According to this configuration, it can meet the general requirements of local dramas such as opera, dance drama, ballet, drama, and Peking opera.
 　Before configuring lamps, you should first understand the types of lamps and their main functions and uses. I will briefly introduce the performance of some lamps and lanterns for selection when configuring the lamps and lanterns.
   1. Spotlight-The spotlight used on the stage refers to the use of a plano-convex condenser in front of the lamp. Compared with the 230W beam lamp, this kind of lamp can adjust the spot size, the beam beam out is more concentrated, and the diffused light next to it is relatively small. There are many kinds of 0.5W to 5KW, and the focal length is long, medium and short. The distance of the viewing distance can be selected according to the needs.
   2. Ribbed lights-or soft lights, but in the TV industry they call this kind of lights a spotlight. On the stage, in order to distinguish the above flat-convex spotlight or beam light, the threaded light is diffuse and soft, so it has a large diffusion area. Sometimes in order to control the diffused light, a title page is added to the front of the mirror to block it. Its characteristic is light. The area is large, unlike spotlights or beam lights, which have obvious spots, the shooting distance is relatively short, and the power is 1KW, 2KW, etc.
 　　3. Back light-this kind of light has no lens in the front, and the light is completely emitted by the larger reflector at the back. With the same 2KW bulb, its brightness is brighter than that of the spotlight, so it is used when strong light source and brightness are required on the stage. Its effect is better than other lamps. The characteristic is that the beam is strong, but the focus point should be paid attention to when dimming. It is not advisable to adjust the focus point on the colored paper or curtain, which will easily cause burning. In addition, black centers often appear in the center during dimming. In order to avoid black center, a ring-shaped baffle is added to the center of the front end of the lamp, which emits a large light spot and is not easy to close. Now a new kind of coating on the reflector to make the outer line of the line transmit backwards to reduce the temperature in front of the lamp, the use effect is very good, the name is cold light super spotlight, the actual structure of the lamp is the same as that of the return light.
 　　4. Imaging lights-or shaped lights, ellipsoid spotlights. There are many beam angles that can be selected and applied according to needs. The main feature is that it can cut the spot into various shapes such as squares, diamonds, triangles, etc., or project various patterns and patterns, and the power is also 1KW, 2KW, etc. Optional configuration.
 　　 5. Simple lamp-also known as PAR lamp, or beam lamp, its structure is to install a mirror bulb in the cylinder and also use a reflective bowl with bromine tungsten bulbs. The main feature is to emit a relatively fixed beam, with a variety of beam angles and light spots. The size cannot be adjusted.
 　　 6. Sky row lamp-high-power astigmatism lamp, used to illuminate the sky curtain from top to bottom, requiring bright and balanced light, and a large illuminated area.
 　　7. Ground row lights-high-power astigmatism lights, used to put on the stage, the lower part of the canopy illuminates upwards, and the light irradiated by the sky row lights are connected evenly.
   8. Astigmatism strip light-long strip, divided into multiple grids, generally can be divided into three or four colors, each grid uses incandescent bulbs with a power of about 200W, and various colors are required to be connected and evenly used for large-area illuminating screens or painting screens , It can also be used for large-area balanced spreading. Various colors of light can also be used at the same time to call out different colored light beams.
   9. General astigmatism lamps-such as iodine tungsten lamps and ordinary floodlights, are mainly used to evenly illuminate a certain area or some scenery.　

　 The above-mentioned lamps and lanterns are the basic lamps and lanterns used in general stage, but other kinds of lamps should be equipped due to different repertoire forms.

For example, the singing and dancing party uses a large number of downlights in addition to the basic lamps, computer lamps, hose lamps, board lamps, various effect lamps, and even smokers, dry ice machines, strobe lights, lasers and projection slides, as well as supporting use For rear projection, to reduce light source spots, special seamless plastic screens, etc., I will not give examples one by one here.
 　　The stage lighting configuration is divided into two parts, the outside of the station and the inside of the station, with the mouth as the boundary
 　　 One. General face light, slap, bag box (building), and long-distance chasing room outside the platform.
   1. According to the scale of the theater stage, there are one surface lighting, two surface lighting, or even three surface lighting. The configuration of the surface light should be based on the different distances, and the spotlights and imaging lights with different collection distances should be configured, and the power should be above 2KW. The first surface light is closer to the proscenium, and some 2KW rib lights and return lights can also be added. Follow spot lamps with suitable focal length and power should be added to the left, middle and right positions of one surface light and two surface lights. The brightness and color change can be controlled by the follower individually.
   2. The slaps are arranged symmetrically on the left and right sides of the proscenium. According to the scale of the theater stage, each side of the slap can be set with one or two slaps, equipped with lamps, mainly spotlights, and a small amount of imaging lights, rib lights, because the slaps are located on the side wall of the auditorium. Very close, when using the rib light, the diffused light often illuminates the nearby wall very brightly, which affects the atmosphere of some scenes, so it is better to use less. A set of follow-up lights should be set in each slap on the left and right for arbitrary control by the follow-up personnel.
 　　3. The foot light is generally outside the proscenium by the side of the orchestra, with a foot light lag, built-in four-color astigmatic light, color separation control, and its length is slightly smaller than the width of the proscenium.
 　　4. The long-distance chasing room is generally located on the left and right of the back of the auditorium, equipped with gas discharge lamps such as xenon lamps, and all control is operated by the chasing staff. If there is no special chasing room, it is often on the left and right sides of the building. Follow spot lights are set in the rear area.
