There are many types of stages in theaters: ordinary proscenium stage, extended stage, island stage, and also called black box stage. Because the stage forms are different, the lighting configuration will definitely be different. Among them, ordinary proscenium stage is more common in the past or present, whether it is rebuilt or newly built theaters, so this kind of stage lighting configuration is even more necessary.
The stage (proscenium stage) has different lighting requirements due to different repertoires performed, so before using the lights, it is necessary to know which repertoires are mainly performed on this stage, so that the configuration of the lights will have clear goals and intentions. For example, some stages are positioned to perform traditional operas or ballets, so the configuration of lamps must be configured according to the requirements of operas and ballets. For example, if the main programs are large-scale singing and dancing, acrobatics, etc., in addition to the basic requirements, special lamp positions and lights, or other effect stage lights should be configured according to the specific program requirements.
Before configuring the lights, you should first understand the types, main functions and uses of the lights. Here, the author briefly introduces some lighting performances for selection when configuring the lights.
1. Spotlight: The spotlight used on the stage is LED Leko Spot Stage Light or Led Profile Light. This kind of lamp can adjust the size of the light spot, the beam angle ranges from 15° to 55°, the diffuse light on the side is relatively small, the power ranges from 200W to 600W, the focal length is divided into long, medium and short, and the distance of the light spot can be selected according to the needs; the light spot can be cut into various shapes such as square, diamond, triangle, etc. This light produced by Grace Stage Lighting has many characteristics: CRI＞95/96, PWM, HSIC control, etc.
2. Studio light: or soft light. This light will have a larger irradiation area than Led Profile Light. Sometimes, in order to control its diffuse light, a cover leaf is added in front of the mirror to block it. Its characteristic is that the light area is large, unlike the spotlight with obvious light spots, the irradiation distance is closer, and the power is 200W, 400W, 600W, etc.
3.LED Par can: also known as LED PAR light, emits a relatively fixed beam: ranging from 10° to 60°, the beam angle width and narrowness are various, and the Zoom LED par light can be used to adjust the spot size.
4. Ceiling lights: high-power diffuser lights, used to illuminate from top to bottom, requiring bright and balanced light, and a large irradiation area.
5. Floor lights: high-power diffuser lights, used to be placed on the stage surface, with the lower part of the sky curtain irradiating upward, connecting with the light irradiated by the ceiling lights, and evenly irradiating from top to bottom.
6. Diffuser strip lights: long strips, divided into multiple grids, generally can be divided into three or four colors, each grid uses an incandescent bulb with a power of about 200W, requiring various colors to be evenly connected, for large-area irradiation of curtains or painting curtains, and can also be used for large-area balanced paving. Various colors of light can also be used at the same time to adjust different color beams.
7. General diffuser lights: such as iodine tungsten lamps and ordinary floodlights, mainly used to evenly illuminate a certain area or some scenery.
The lamps introduced above are only the basic lamps for stage lighting. Due to the different performances, other types of lamps should be configured. For example, in addition to the basic lamps, a large number of par lights, moving head lights, hose lights and other effect lamps are used in song and dance evenings. Even fog machines, dry ice machines, strobe lights, lasers and projection slides are also required, as well as matching post-projection, light source spot reduction, special seamless plastics, etc.
