What are the lighting methods, lighting types and emergency lighting equipment? Seek an answer

There are three kinds of lighting methods: general lighting, general lighting in residential areas and local lighting. The classified name of' mixed lighting' is not used in the lighting mode, because it is easily confused with the lighting of natural light and artificial light, or with the lighting method of mixed light of two different artificial light sources. District general lighting is a kind of lighting mode in which lamps are relatively concentrated (uneven) in order to improve the illumination in a certain area. Using this lighting mode in civil buildings can save energy and lighting costs. Local lighting alone can not form comfortable ambient brightness in the field of vision, thus reducing visual comfort, easily causing visual fatigue and affecting work efficiency. Therefore, Shenzhen decoration experts suggest that local lighting places must be matched with general lighting systems. Lighting types are divided into normal lighting, emergency lighting, duty lighting, guard lighting and obstacle lighting. Emergency lighting includes three different lighting purposes: (1) evacuation lighting. The ground horizontal illumination of evacuation lighting should not be less than 5% to meet the requirements of crowd evacuation. (2) Safety lighting. The brightness of safety lighting in the workplace should not be less than 5% of the general vision in the workplace. (3) standby lighting. The brightness of the standby lighting is 10% of the total vision or the total vision of the partition. The brightness of duty lighting depends on the importance of its position. Under normal circumstances, when the requirements are not high, emergency eyes can be used as duty lighting.
