The stage lighting is configured in the theater
Inside the theater stage, there are a variety of stage, have a common frame type stage, has thrust stage, have island type stage, there are also known as the black box of the stage, because the stage forms are different, so the configuration requirements of lamps and lanterns is not the same. For convenience, I here only talk about the ordinary frame type stage, the stage no matter in the past or is now rebuilding and new theatre are more, so talk about this kind of stage lighting configuration is much needed and necessary.
The stage (the frame is the frame stage, the post all the same) because the play that plays is different to the requirement of the lamps and lanterns will be different also. So we have to be clear in front of the lighting fixtures that there is a more specific target and purpose in this stage. If the stage is located in the traditional opera, the ballet is the main, the configuration of the lamps and lanterns must be configured according to the requirements of opera and ballet. Such as large-scale song and dance, miscellaneous Nv is the special programs such as lighting in addition to the basic requirements for configuration, should according to the specific program requirements, to add special lamp and the configuration of lamps and lanterns, so here it is difficult to clear narrative. So I am here only talk about theatre stage, the basic configuration of lamps and lanterns of in accordance with this configuration, can satisfy the general jiang, such as opera, ballet, ballet, drama, Peking Opera and other local operas.
Before configuration lamps and lanterns, should understand the type of lamps and lanterns and their main function and usage. I am here simply to introduce the performance of some lamps and lanterns to provide the time potential choice for lamps and lanterns.
1. Spotlight - with spotlights on the stage is to point to in front of the lamp use flat convex condenser is concerned, this kind of lamps and lanterns can adjust the light spot size, the beam more concentrated, next to the diffuse light is small, power is 0.5 W to 5 kw of kinds, has short, medium and long focal length, depending on the range of distance, according to the need to choose.
The luowen lamp, or soft light, is called the spotlight in television. On stage in order to distinguish the flat convex spotlights loose and soft, so use the diffuse area, sometimes in order to control its diffuse light through the block in front of the mirror with the cover page, its characteristic is light district area is large, don't like the feeling together joy lamp have obvious spot, target range, power is 1 kw, 2 kw, etc.
3. The back light -- the light in front of the lens, the light completely on behind a larger reflector injection, with the same 2 kw of light bulbs, its brightness is concentrated to bright, so to be strong on the stage light and brightness. Its effect is better than other lamps and lanterns, is characterized by strong light beam, but the dimming should pay attention to its focal point, is unfavorable to focus on the color paper or curtain, such easy to cause burns, and often appear in the center of the dimmer when "dirty", in order to avoid the "dirty", adding a ring baffle in the center of the lamp front-end, the injection of light and not easy to fold. Now a new reflective bowl on coating line the perimeter backward transmission, to reduce the light in front of the temperature, the use effect is very good, the name of cold light super spotlight, the actual structure and back into the light of the lamp is the same.
An image lamp -- or a shaped lamp, an ellipsoid light. Can choose according to need the beam Angle has a variety of applications, the main feature is like the slideshow will flare shapes of cutting square, diamond, triangle, or casting required all sorts of design patterns, power is 1 kw, 2 kw and other optional configuration.
5. Jane lamp - also called PAR lamp, or light beam, its structure is within the cylinder under the mirror light bulbs also useful reflective bowl of bromine tungsten bubble, main feature is that penetrate the fixed beam, beam Angle width of the light spot size can adjust.
Skylights -- large, diffused light lamps are used to illuminate the canopy of the sky, which requires light and balance and large area of exposure.
Floor lamp -- the light of a large power, which is used for the stage face, and the lower part of the canopy of the sky is illuminated by the light from the light of the sky.
Article 8. Astigmatism, elongated, divided into multiple, generally can be divided into three or four kinds of color, in each case with incandescent light bulb 200 w, require all sorts of color from the following, for large area light curtain or curtain use, also can be used for large area equilibrium spread the use of light, all sorts of color of light can also be used at the same time, bring up different colored light.
General astigmatism lamps, such as iodine tungsten lamps and ordinary floodlights, are mainly used to light up a certain area, or some set of scenery. The lamps and lanterns described above are the basic lamps used for the general stage, but different kinds of lamps should be configured for different forms of play. Such as singing and dancing party in addition to the basic lamps and lanterns of extensive use of tube light, light, tube light, want to plate lamp, the effect of all kinds of lamps and lanterns, and even provide a fog machine, dry ice machine, the flashing light, laser and projection slideshows, and used for cast light after use, reduce light spots, special seamless plastic curtain, etc., not for one by one here.
The stage lamps and lanterns are configured with the mouth as the boundary and two large parts of the stage
One, the outside of the table is usually divided by the light, the face, the box (building block), the long distance pursuit room.
The surface light is based on the scale of the stage of the theater, and there is a light, two surfaces, or even three levels of light. The configuration of the face light lamp should be based on the distance from the distance, the lamp of different sets, the image lamp, the power should be over 2KW. The first surface of the light is closer to the mouth of the platform, and it can also be added with some 2KW rib lights and a backlight. The light of a surface and two surfaces in the left, middle and right positions should be equipped with the suitable focal length suitable for the lighting lamps, which can be controlled by the person who is in charge of the light and color.
2. Slap on both side entablature symmetric Settings, according to the size of the stage, each ear, light can be set up one or two, the configuration of lamps and lanterns, give priority to with the spotlight, lamp, rib lamp, can be a small amount of configuration imaging as a slap in the face by the audience hall side walls are very close, the light use rib, the diffuse light often near the walls as very bright, affect some scene atmosphere, so appropriate use fewer is better. Each one of the face should be set up for the light of the light to be used for the control of the light.
The foot light is normally on the edge of the platform in the area of the music pool, set foot light bad, the built-in four-color scattered light, the color control, its length is slightly less than the width of the station mouth.
4. The distance the spotlight chamber, generally in the audience around the back of a hall, configuration in gas discharge lamp, such as xenon lamp, all control by the spotlights personnel operations, such as room cannot be set for the spotlight, after is often at the left and right sides of the floor area is set to follow spot.
