Basic knowledge of dance lighting design 1

Common knowledge of stage lighting design 1. Commonly used light positions of stage lighting If you want to configure professional stage lights, you must first understand the common light positions of stage lighting fixtures. This is an important step in selecting the correct configuration. 1. Surface light: the light projected from the top of the audience to the stage. Its main function is the front lighting of the characters and the basic light spreading of the entire stage. 2. Slap: Located on both sides of the stage entrance, the light is cast obliquely on the stage. It is divided into upper and lower layers. It mainly assists surface light, strengthens facial lighting, and increases the three-dimensional sense of characters and scenery. 3. Column light (also called side light): The light projected from both sides of the stage is mainly used to illuminate the two sides of characters or scenery to increase the sense of three-dimensionality and outline. 4. Top light: The light projected from the top of the stage to the stage is divided into one row of top light, two rows of top light, three rows of top light... etc. from front to back. It is mainly used for general lighting of the stage, enhances the stage illumination, and has The fixed-point illumination of many scenery and props is mainly solved by top lighting. 5. Backlighting: Light projected from the opposite direction of the stage (such as top light, bridge light, etc.) can outline the outlines of characters and scenery, enhance the sense of three-dimensionality and transparency, and can also be used as a specific light source. 6. Bridge light: The light projected onto the stage from the overpasses on both sides of the stage is mainly used to assist the column light to enhance the three-dimensional effect. It is also used in other directions where the light position is inconvenient to project, and can also be used as a specific light source. 7. Footlight: The light projected from the platform in front of the proscenium to the stage mainly assists the surface lighting and eliminates the shadows formed by the characters' faces and jaws illuminated by surface lights and other high positions. 8. Sky-to-ground light emission: The light projected from the top and bottom of the canopy to the canopy is mainly used for lighting and color changes of the canopy. 9. Flowing light: Located on the flowing light stands on both sides of the stage, it mainly assists the bridge light and supplements the light on both sides of the stage or other specific light. 10. Chasing light: The light position required from the auditorium or other locations. It is mainly used to track actors’ performances or highlight a specific light. It is also used for the host. It is a close-up stroke of stage art and provides the finishing touch. effect. 2. Commonly used lamps and characteristics 1. Spotlight: It is one of the most widely used main lamp types in stage lighting. Currently, there are 1KW and 2KW on the market, with 2KW being the most widely used. It irradiates concentrated light, and the edge of the spot outline is relatively clear, which can highlight a part, and can also enlarge the spot to illuminate an area. As the main light source of the stage, it is often used for surface light, slap, side light and other light positions. 2. Soft light: The light is soft and well-proportioned, which can highlight a certain part without any harsh light spots, making it easy to connect several lights. Common ones are 0.3KW, 1KW, 2KW, etc. It is mostly used for close-range light positions such as column light and flowing light. 3. Backlight: It is a reflective lamp, which is characterized by hard light quality, high illumination and long range. It is an economical and efficient strong light. The common ones are 0.5KW, 1KW, 2KW, etc., with 2KW being used the most. 4. Astigmatism lamp: The light is diffuse, symmetrical, and has a large projection area. It is divided into sky-dispersed astigmatism and ground-dispersed astigmatism. The common ones are 0.5KW, 1KW, 1.25KW, 2KW, etc., which are mostly used for canopy illumination and can also be used for theater chairs. General lighting of the stage. 5. Modeling light: The principle is between the following light and the spotlight. It is a special lamp mainly used for modeling projection of people and scenery. 6. Footlights (also called strip lights): soft light and wide area. Mainly used for lighting and coloring in mid-scenes and netscapes, and can also be used as auxiliary surface lighting at the entrance of the stage. 7. Beam column lamp (also known as downlight): currently widely used, such as PAR46, PAR64 and other models. It can be used to illuminate characters and scenery in all directions. It can also be installed directly on the stage and exposed to the audience to form a light array, which serves the dual functions of stage decoration and lighting. 8. Projection slides and canopy effect lights: can form an overall picture on the stage canopy, as well as various special effects, such as: wind, rain, thunder, electricity, water, fire, smoke, clouds, etc. 9. Computerized light: This is a kind of intelligent lamp controlled by DMX512 or RS232 or PMX signal. Its light color, spot and illumination are better than the above conventional lamps. It is a kind of intelligent lamp developed in recent years. It is often installed in surface lights, The running color, shape, picture, etc. of the top light, steps behind the stage, etc. can all be programmed to run. Due to the different power levels, the use on the stage should be different. Generally, low-power computer lights are only suitable for use in dance halls. On the stage, low-power computer light lines and spots are often blurred by stage spotlights, backlights, etc., so special attention should be paid to their selection. 10. Follow spotlight: It is a stage lighting fixture. It is characterized by high brightness and the use of lens imaging, which can present a clear spot. By adjusting the focal length, the virtual spot can be changed. There is a movable light bar, which can easily change the color, and the lamp body can run freely, etc. There are many varieties on the market, and the indicators are marked in different ways. Those based on power are: 1KW tungsten halogen light source, 1KW dysprosium light source, 1KW metal halide light source, 2KW metal halide light source, etc. There are also light chasing based on distance. Lights (light intensity and illumination at a specific distance), such as 8-10m follow-up light, 15-30m follow-up light, 30-50m follow-up light, 50-80m follow-up light, etc., and are functionally divided into: For mechanical follow-up lights, the focus adjustment, diaphragm, and color change are all done manually; the other type is the computer follow-up light, whose focus adjustment, diaphragm, color change, and color temperature adjustment are all done automatically by pushing and pulling electrical appliances, so in When choosing, you must carefully select various indicators.
