The Research On Building Fire Evacuation Lighting System

With the rapid development of city construction in China, the volume of modern buildings are expanding. The function of the building is more complexity; personnel density and the flow of people are increasing in the building. To provide of scientific and standardized emergency lighting system for the people in the use of complex internal features in the building is necessary. When the power supply interrupted,especially the fire caused by the power interruption, the importance of fire emergency lighting will ensure evacuation in the building and personal safety, in order to prevent the accident caused regeneration, therefore, the position of emergency lighting cannot be replaced.Firstly, this dissertation discusses the research status of the emergency lighting technology, and analysis the series factors in influence of the quality of emergency lighting, that include the power supply, light source, battery, lamps, wire laying and protection, especially works on the light source and the battery technology that could impact directly to the reliability of using emergency lighting. Then it studies on the differentiation of new and old Code for design of automatic fire alarm system to analyses the development of evacuation lighting technology and produced in the building design changes.Combined with the practical cases, the discussion of civil building design of fire emergency power supply, power supply system, line laying, arrangement of fire-fighting equipment, and control of the fire lighting are designed.
