LED emergency lights must be equipped with emergency equipment - inverter (inverter). The inverter converts the DC energy (battery, storage bottle) into power flow (usually 220v50HZ sine or square wave). Emergency power supply, usually DC battery reverse into 220V AC. In popular terms, an inverter is a device that converts a direct current (DC) into an alternating current (AC). The utility model is composed of an inverter bridge, a control logic and a filtering circuit
Electric AC normal supply, inverter the battery charging, emergency lighting group is in standby state; when power cut or attacks, earthquakes, explosions and other accidents or other emergencies caused by electric AC suddenly interrupted when the inverter was launched into battery power to light lamps, the conversion time of less than 0.1 seconds. Matching different capacity of the battery, can achieve 1-3 hours of emergency lighting time, adapt to the needs of different occasions. Can be used in the -25 - +70 temperature environment.
