演播室灯光系统主要由专用配电系统、调光系统、灯具等组成。目前根据节目制作的需要有直播和录播两种方式:即直播型灯光系统和录制型灯光系统。直播型演播室要求节目直播时,调光设备和供配电系统的运行要保证绝对的安全可靠,不能够出现任何问题。如果灯光系统运行出现故障时则该系统应有补救措施。因此,在设计直播型演播室的灯光系统方案时,就应从设计和设备上考虑有应急备份系统。当主系统出现故障时,备份系统可立时启动运行,并尽可能地缩短出现故障的时间。所以,设计直播型演播室的灯光系统时,建议可从以下几方面来考虑灯光系统的备份措施。
Studio lighting system mainly by a dedicated power distribution system, dimming systems, lamps and other components. At present, according to the needs of program production live and recorded in two ways: the live-type lighting system and recording light system. Live studio broadcast programs require live, dimming equipment and power distribution system to ensure the operation of absolute safety and reliability, can not be any problem. The system should have a remedy if the lighting system fails in operation. Therefore, when designing a lighting system solution for a live studio, an emergency backup system should be considered in terms of design and equipment. When the primary system fails, the backup system can start up immediately and minimize the time it takes to fail. Therefore, the design of live studio lighting system, it is recommended from the following aspects to consider lighting system backup measures.
