Emergency lighting power can be roughly divided into the following:

(1) from the feeder lines separate power network effectively and the normal power supply.

(2) diesel generator.

(3) batteries: mainly emergency lamp with built-in battery, battery and battery set the partition set set.

(4) combined power supply. That is, any of the above two and above to the combination of three power supply mode.

Conversion time according to the provisions of the actual engineering and relevant specifications: standby lighting conversion time should not be greater than 15s; evacuation lighting conversion time should not be greater than 15s; safety lighting conversion time should not be greater than 0.5s. According to the different switching time of the lighting, the corresponding emergency power supply should be selected to achieve the best emergency response. For shopping malls and other large space due to different decoration styles, can be used in the decoration of the lamps and batteries, but also can be set separately and usually do not light the emergency lighting.
