自动备用照明警示灯与应急灯的研究与设计

Research and Design of Automatic Standby Lighting Warning Lamp and Emergency Lamp

针对建筑工地危险地段警示、道路施工临时警示、海上灯塔警示等可能需要整晚照明,地下通道需要24小时照明,这些特殊地段的照明灯具是不允许"损坏的"。为了解决这个难题,可以使用应急灯电路,但应急灯一般不能坚持多长时间照明;另一个思路,设计一套备用照明电路,利用干簧管检测主灯具的通断,通断信号控制备用灯具点亮,同时发出声音报警,提醒工作人员及时更换损坏的主灯具,实现只要供电正常可以24小时不间断提供照明服务。该设计不同于应急灯模式。

Aiming at the construction site, construction of temporary road danger area warning warning, warning the sea lighthouse may require night lighting, underground channels require 24 hours lighting lighting, these sections are not allowed to ＂damage＂ . In order to solve this problem, you can use the emergency lamp circuit, but not how long emergency lamps for general lighting： another idea, design a set of spare lighting circuit, using reed detection lamp switch on-off signal control standby lamp is lighted, and voice alarm, to remind staff to replace the damaged main lamp in time, as tong as the normal power supply can achieve 24 hours of uninterrupted service to provide lighting. The design is different from the emergency light mode.
