LED emergency lights must be equipped with emergency devices - inverter (inverter). Inverter is the DC power (battery, battery) into alternating current (usually 220v50HZ sine or square wave). Emergency power supply, the general is the DC battery into 220V AC. In general, an inverter is a device that converts direct current (DC) into alternating current (AC). It consists of inverter bridge, control logic and filter circuit.
When the mains AC is supplied normally, the inverter makes the emergency lighting battery pack in the charging and standby state. When the utility power is interrupted or the earthquake, attack, explosion or other emergency or other emergency caused the sudden interruption of the electricity, the inverter immediately Start, convert to battery power to continue to light the lamp, the conversion time is less than 0.1 seconds.
