Stage Television lights (design for stage.
Guangzhou stage lighting: in stage performances and film shooting, in order to achieve certain lighting effects lighting and the use of a class of lamps It helps content of the performance of the program, reflecting the author's creative intent, express artistic atmosphere, and. audience, photography (image) machine to get the right color perception and exposure. with other lamps is different, most of these lamps have to change the angle of beam spread and extent of soft light and color features, and is equipped with a focus, aperture, filter color frame and other special institutions.
A Brief History
The earliest development stage lights, movie lights, followed by television lights later. The early show with natural light torches, oil lamps, candles and other illumination appear .17 century picture frame stage, stage lights by the uncontrolled development to be able to control the light source and light intensity Easy color lamps. 1804, there has been heated to the combustion of acetylene gas quicklime reach incandescence new light and lighting for stage lighting .19 century, the stage lights have used gas lamps, kerosene lamps and electric light, in terms of lighting appears spotlight and floodlight lamps (floodlights), and dispersed in the centralized control of lighting inside and outside the arena, so the stage lighting gradually into the art lighting .20 1960s, the stage lights has tended serialization, systematization and automation, lighting adopt a comprehensive approach and computer control, and extensive use of laser and voice effects.
Early film incandescent lamp, a carbon arc lamp and high-pressure mercury lamp as a light source for shooting in black and white .20 1960s began using halogen lamps, a color temperature of 3200k, CRI 99, to ensure that the color reproduction of color film. the early 1970s, China invented the DC dysprosium, holmium lights, color temperature 5500k, the color rendering index of 80 or more, and with no stroboscopic exchange, etc., to ensure that the daylight-type color film color reproduction and interior outdoor photo.
TV lamp is developed in the 1950s on the basis of stage, film lights on. Because of the sensitivity of the camera tube rising, the lamp power corresponding decrease in television, especially the rapid development of small studios and CCTV, to TV lights presents special requirements, there has been the lever control lights, electric lights.
Composition
Guangzhou Television head light stage light from a light source, optical components, mechanical parts and electrical components .① sources have incandescent, halogen and metal halide lamps and other. Their luminous lanes dot, strip or rectangular and other geometric shapes, color temperature 3200k, 5500k are two, color rendering index of 80 or more .② optical component according to the shape of the body and the light source lighting, imaging, effects, and use requirements, reflector, a field lens (condenser), an objective lens and other mechanical components constituting the optical system .③ There envelope and block light, heat, insulation and so on, and ensure a stable and reliable optical systems play a variety of functions, including light beam angle zoom and received a small, ordinary lens or focusing zoom lens, the effect of the motor mechanical transmission, etc. .④ electrical components including power supply, light attachment (trigger, ballast, rheostat, etc), dimmers and the effects of the drive motor continuously variable control of electrical lines and so on.
Feature
Stage lights can help the audience to directly see the whole scene or part of the scene on the stage, setting the stage looks so lifelike, better demonstration of the artistic level of the writers and works of creative intent, large-scale changes in light and shade, lighting The area is also large. Television lights use in the studio, the studio or field scene, the audience "is a movable camera or camcorder and for technical processing, close-range and more, in addition to artistic lighting effects lighting but also have the imaging tube or film the role of correct exposure, especially for color reproduction is good, in the light (interior shot) requires light color temperature of 3200k, a color rendering index of 90 or more, under the sun (on location) to 5500k and 80 above.
Television stage light beam emitted according to their characteristics into the spotlight, astigmatism lights and effects lights three categories.
Spotlight
Get local projection lamp light effect. Beam angle adjustable, the light is more concentrated, there is a spot edge with color filter frame according to the clarity of the edge contour of the spot can be divided into the following three kinds .① Soft Spotlight contour light soft, commonly Fresnel lens, also known as the Fresnel lens spotlight .② plano-convex spotlight contour clearer light, the intensity is also large, is a commonly used lighting on stage spotlight .③. using imaging principle , the projection of the beam to produce a significant boundary between light and dark spot on the stage, used to track the performers or projection lighting local scope.
Astigmatism lights
Beam spread angle, even without edge soft spot traces of a type lamps, it does use a reflector, and with a filter frame. There grid lights, foot lights, canopy lights astigmatism, day sheet astigmatism lights, quadruple and six of astigmatism lights, exterior lights astigmatism and many other varieties.
Effect Light
Guangzhou searchlight use of lighting, a combination of mechanical and electrical drive control, cast a variety of scenery, the weather changes and illusory nature scene of a film class stage lights. Can exhibit a variety of stationary and movable scenery scene rain, snow, flame, cloud , wave, lightning, the sun rises, etc., can also be used as a background dynamic shadow show various changes in the landscape, like mine.
