How to design emergency lights in stairwells?
In an emergency, the fire protection design cannot be sloppy, and the fire corridor is related to the safe evacuation of people's lives and property. Since it is a ladder room with fire escape, it is necessary to carry out fire protection design in accordance with relevant standards. In particular, poorly designed emergency lights can increase the likelihood of a major accident during an evacuation. And the fire escape has lost its emergency function.
Emergency lights, also known as emergency lighting, are lighting devices that are often used to facilitate the evacuation of people and allow them to continue working if there is a problem with the normal lighting system. Emergency lights are generally divided into three types: evacuation lighting, backup lighting and safety lighting. The role of evacuation lighting is to help people find the exit direction of the building well when the normal lighting system fails. Backup light fixtures are light fixtures designed to help people continue to function normally in a critical situation. Safety lighting is when people enter a dangerous place. Please ensure your own safety in the event of a normal lighting failure.
Design requirements for intelligent fire emergency lighting manufacturers
As the core of the building, the stairwell is not only a place where people are relatively concentrated and prone to accidents, but also plays an important role in emergency evacuation. In the event of a fire or a sudden power failure, emergency lights in stairwells play an important role, so great care must be taken when designing emergency lights in stairwells. GB50016-2014 "Code for Fire Protection Design of Buildings" stipulates that fire emergency lights should be turned off or installed in smoke-proof stairwells, and the emergency evacuation illuminance (usually low-level illuminance) of stairwells also has essential requirements. It must be higher than the ground 5.0lx). In addition, in the process of emergency light design, it is necessary to reasonably select the power control method of the emergency light system. You need to use the calculation method to check whether the lighting of the emergency light meets the requirements of the standard requirements and the needs of the standard value.
