Use of fire emergency lights

Use of fire emergency lights

The emergency lighting system is mainly based on the independent control of its own power supply. The normal power supply is connected to the general lighting power supply circuit, and the emergency light battery is usually charged. When the normal power supply is cut off, the backup power supply (battery) automatically supplies power. This form of emergency light has a large number of electronic components such as voltage transformation, voltage stabilization, charging, inverter, and storage battery inside each lamp. The emergency light needs to be charged and discharged during use, maintenance, and failure.

The other is the centralized control type of centralized power supply. There is no independent power supply in the emergency lamps. When the normal lighting power supply fails, the centralized power supply system supplies power. In this form of emergency lighting system, the complicated electronic circuits inside all lamps are omitted, emergency lighting lamps are no different from ordinary lamps, and the centralized power supply system is set in a dedicated room.
Compared with emergency lamps with independent control of their own power supply, centralized control of emergency lamps with centralized power supply has the advantages of convenient centralized management, user self-inspection, fire supervision and inspection, prolonging lamp life, improving emergency evacuation efficiency, etc. The system has good reliability and service life. long, convenient maintenance and management, low system price. However, since there is no backup power supply (battery) in the centralized power supply centralized control type emergency lighting fixture, if the power supply line fails, it will directly affect the normal operation of the emergency lighting system, so the power supply line is laid with special fire protection requirements.
