I will take you to learn what power of emergency lights, and for everyone to introduce the relevant knowledge of emergency lights in detail.


   In general, emergency lights with dual power supply, mainly refers to the alternating current and battery backup. The backup battery is charged when the AC power is on. And once the AC power to stop, the backup battery will start to the emergency light power supply, through a certain circuit will be low-voltage battery into lamps available voltage, thus lighting.

In our country, the control methods of emergency lights mainly include two types: self-contained power supply independent control and centralized power supply centralized control. Under normal circumstances, the normal power supply comes with power emergency light ordinary lighting power supply circuit, usually on the battery charge, the normal power cut off, the battery automatically powered. Centralized centralized control means that there is no backup power in each emergency light. If the line fails, the emergency light will not work normally. If you adopt this kind of centralized control method, you need to conduct a certain fire prevention on the whole circuit.


Emergency light maintenance methods

1.Regularly check the appearance of emergency lights whether there is deformation of the phenomenon of damage, whether it can work properly, and to be replaced.
2.The protection of emergency light circuit voltage is normal, and within the specified range.

Regular emergency lights to charge, and to ensure that once every three months up to 20 minutes of discharge operation. Especially for a long time without emergency lights, the battery should be emptied.chinalighting fair
