The emergency lighting conversion time is determined according to the actual project and relevant regulations.
(1) The conversion time of standby lighting should not exceed 15s;
(2) The conversion time of evacuation lighting should not exceed 15s;
(3) The conversion time of safety lighting should not exceed 0.5s;
The conversion time is determined mainly from the necessary operations, handling and possible accidents and economic losses. Some places require shorter conversion time. For example, the checkout counter in the mall center should not be larger than 1.5s; for the production sites with serious dangers, It should be determined according to the actual needs of its production. For automatic lighting and standby lighting, automatic conversion is easy. Even if a diesel generator set is used as the emergency power source, automatic start and automatic conversion are achievable. For safety lighting, the conversion time is very short for 0.5s, so the diesel generator set cannot be used as the emergency power source, and the fluorescent lamp cannot be used as the light source. The incandescent lamp that is instantaneously ignited must be used and must be automatically converted.
