The Quzhou Broadcast Television Transmission Center Studio Light Engineering Design Analysis

衢州广电传输中心演播室灯光工程是涉及单人、双人新闻,访谈,综合性文艺等多种节目类型的一个系统工程。灯光设计方案要具有先进性、实用性、可靠性、经济性以及较强扩展性。演播室拍摄色温为3000至3200K。按国家标准,演播室的综合垂直照度应达到2000LX。由于摄像机灵敏的提高,新闻访谈类节目的照度在1200LX左右,综艺类节目的照度在1600LX左右即可。小型演播室灯具选用电动垂直吊杆来悬挂灯具,综艺演播室则采用电动的水平吊杆来悬挂灯具。水平吊杆采用复式提升结构,极大的提高吊杆的承载能力和稳定性。随着电视技术的日益发展,灯光设计的创作已经发展到讲究艺术创新的阶段。通过光效对比,光束造型,色调调整等,使演播室灯光效果具有艺术美感和艺术创造力。

The Quzhou Broad Electricity Transmission Center studio light project is involves the single, the two person news, the interview, comprehensive literary arts and so on a many kinds of program type systems engineering. The light design proposal must have the sophistication, the usability, the reliability, the effieieney as well as the strong extension. The studio photography color temperature is 3000 to 3200K. According to the national standards, the studio synthesis vertical degree of illumination should aehieve 2000LX. As a result of camera keen enhaneement, news interview class program＇ s degree of illumination about 1200LX, synthesis sill class program＇ s degree of illumination about 1600LX then. The small studio lamps and lanterns select the electrically operated vertieal suspension bar to be hanging the lamps and lanterns, the synthesis skill studio use the eleetrieally operated back bar to be hanging the lamps and lanterns. The baek bar uses the multiple promotion structure, enormous sharpens suspension bar＇ s bearing capacity and the stability. Along with television teehnology＇ s flourishing more and more daily, the light design＇ s creation already developed is fastidious about the artistie innovation the stage. The light effect eontrast, the light beam modelling, the hue eontrol and so on, enables the studio lighting effects to have the artistie esthetie sense and the artistie ereativity.
