Selection of top-level chips, switch transistors, and use of fire emergency lights: Summary of fire emergency lighting system: The fire emergency lighting system mainly includes accident emergency lighting, emergency exit signs, and indicator lights. It is set up to guide trapped personnel to evacuate or carry out firefighting and rescue operations after the normal lighting power is cut off in the event of a fire. However, in daily inspections, it was found that there are many problems in the selection, installation, and use of fire emergency lighting fixtures in the unit. Therefore, the reasonable selection of power supply control and wiring methods for the emergency lighting system, as well as daily maintenance work, directly affects the effectiveness of the fire emergency lighting system. Theme: Installation and maintenance of emergency lighting power supply control methods. The advantages include reliable operation, high stability, and long service life. It is suitable for high-rise buildings such as factories, hotels, shopping malls, and buildings.
