Emergency lighting is different from ordinary lighting, which includes three types: backup lighting, evacuation lighting, and safety lighting. The conversion time is determined based on actual engineering and relevant regulations. Emergency lighting is an important safety facility in modern public and industrial buildings, which is closely related to personal safety and building safety. When a fire or other disaster occurs in a building and the power supply is interrupted, emergency lighting plays an important role in personnel evacuation, fire rescue work, and the continued operation or necessary operational disposal of important production and work.
