Common light levels of stage lighting If you want to configure professional stage lighting, you must first understand the common light levels of stage lamps. This is an important link in the correct selection of configuration. 1. Surface light: the light projected from the front of the audience to the stage, which is mainly used to illuminate the front of the characters and spread the whole base light. 2. Slap in the face: The light obliquely projected from the stage on both sides outside the podium is divided into upper and lower layers, which mainly assist the surface light, strengthen the facial lighting, and increase the three-dimensional sense of people and scenery. 3. Column light (also called side light): The light projected from both sides of the platform entrance is mainly used to illuminate both sides of people or scenery to increase the three-dimensional sense and outline sense. 4. Top lights: The lights projected from the top of the stage are divided into one row of top lights, two rows of top lights and three rows of top lights. From front to back, it is mainly used for general lighting of the stage to enhance the illumination of the stage, and there are many fixed-point lighting of scenes and props, which are mainly solved by overhead lights. 5. Backlight: The light projected in the opposite direction of the stage (such as overhead lights and bridge lights) can outline the names of people and scenes, enhance the three-dimensional sense and transparency, and can also be used as a specific light source. 6. Bridge light: the light projected onto the stage at the overpass on both sides of the stage, which is mainly used to assist the column light and enhance the three-dimensional sense. It is also used in other directions where the light level 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 stage to the stage, which mainly assists the surface lighting to eliminate the shadow formed by the surface lighting on people's face, chin and other heights. 8. Light of heaven and earth: The light projected up and down the canopy is mainly used for illumination and color change of the canopy. 9. Streamer: Located on the floating 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 lights. 10, light chasing: the light level required from the audience or other positions, mainly used to track the performance of actors or highlight some light, but also used for the host. It is a close-up pen of stage art, which plays the role of making the finishing point. Second, common lamps and features 1, spotlight: it is one of the most widely used main lights in stage lighting. At present, there are 1KW and 2KW in the market, among which 2KW is the most widely used. It focuses the light, and the outline edge of the light spot is clear, which can highlight a part and enlarge the light spot to illuminate an area. As the main light source of the stage, it is often used for surface light, slap in the face, side light and other light levels. 2. Soft light lamp: the light is soft and symmetrical, which can not only highlight a certain part, but also have no blunt spot, which is convenient for connecting several lamps, such as 0.3KW, 1KW, 2KW, etc. It is mostly used for short-distance light levels such as column light and streamer light. 3. Back light: it is a reflective lamp, 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. , and 2KW is the most used. 4. Astigmatic lamp: The light is diffused, evenly distributed and has a large projection area. It can be divided into sky astigmatism and ground astigmatism. Common ones are 0.5KW, 1.25KW, 2KW, etc. , mostly used for skylight lighting, but also can be used for general lighting of the theater podium. 5. Modeling lamp: The principle is between spotlight and spotlight. It is a special kind of lamp, which is mainly used for modeling projection of people and scenery. 6. Footlight (also known as strip light): soft light and wide area. It is mainly used to distribute light and color to the middle scene and Netscape, and can also be used to assist the surface lighting of the platform entrance. 7. Column lamp (also called downlight): It is widely used at present, such as PAR46, PAR64 and other models. It can be used to illuminate people and scenery in all directions, or it can be directly installed on the stage and exposed to the audience to form a light array, which has the dual functions of stage decoration and lighting. 8. Projection slide and ceiling effect light: It can form a whole picture and various special effects on the stage ceiling, such as wind, rain, thunder, electricity, water, fire, smoke and clouds. 9. Computer lamp: This is an intelligent lamp controlled by DMX5 12 or RS232 or PMX signals, and its light color, spot and illumination are superior to the above conventional lamps. It is an intelligent lamp developed in recent years, and is often installed in the headlights, ceiling lamps and back steps of the stage. And its color, shape and chart can be programmed during operation. Because of the different strength, the application on the stage is also different. Ordinary low-power computer lights are only suitable for ballroom use. On the stage, the light and facula of low-power computers are often ignored by stage spotlights and return lights, so special attention should be paid when choosing. 10, spotlight: it is a stage light, characterized by high brightness, and can present a clear spot by using lens imaging. By adjusting the focal length, the spot can be changed. There is a movable diaphragm, which can easily change color and the lamp body can run freely. At present, there are many varieties on the market, and the labeling methods are different, such as: 1KW tungsten halogen light source, 1KW dysprosium light source, 1KW metal halide light source, 2KW metal halide light source, etc. And there are distance-based spotlights (light intensity and illumination at a specific distance), such as 8-65438+. The other is computer spotlights, whose focusing, aperture, color change and color temperature adjustment are all done automatically by pushing and pulling electrical appliances, so we must carefully select various indicators when choosing. Third, the design and promotion of stage lighting color changer greatly simplifies the number of stage lamps, reduces the labor intensity of lighting workers and saves the investment amount. It is an indispensable instrument for stage configuration at present. At present, there are mainly mechanical color changers and electric color changers on the market. Supplement: 1. Stage mechanical color changer: the mainstream product in the mid-1980s and 1990s, with simple design and low price, has been nearly eliminated at present. 2. Stage computer color changer: It is a new color changer developed in recent years. It adopts the international standard DMX-5 12 signal output, which can be controlled by a special controller or connected to a computer dimmer. With the characteristics of multi-mode, high precision, large capacity and long control distance, it has become the mainstream product of color changer in the market at present. Four. Lighting control equipment At present, the dimmers on the market mainly include analog dimmers and digital dimmers, and their characteristics are: 1. The analog dimmer adopts analog dimming technology, and the output signal is 0- 10V, with one-to-one output. The general analog dimmer has simple design, few controller circuits and poor dimming curve, but the market price is low and it is easy to learn and master. It was the mainstream product from the late 1970s to the mid-1990s. There are three, six, nine, 12, 18, 24, 60, 120, etc. Each power is 8KW, but there are 2KW, 4KW, etc. The number of paths is mostly integrated machines, and the number of roads is mostly split machines. 2. Digital dimmer: The digital signal is DM5 12, and the recorder technology is adopted. Digital dimming meter is easy to use (especially in large loop), and its dimming function, backup function, grouping function and dimming curve are better than analog dimming meter, and its performance and price are reasonable, which is very popular with users. Common roads are 12, 36, 72, 120, 240 and 1000, which are 2KW, 4KW, 6KW and 8KW respectively. After knowing the position, characteristics, control equipment and color changer of the lamp, we can design the correct use scheme according to their respective characteristics, the size of the use scale and the complexity of using the lamp.
