Emergency lighting

The use of batteries is only used in places where it is inconvenient to access the power supply, such as night market vendors, trains, ships, buses, field lighting, due to short life of emergency lamps, low luminous efficiency, short lamp life and electrophoresis. Therefore, there is no one to use under the normal conditions of AC power supply. At present, some manufacturers apply this technology to the eye protection table lamp, and the AC power is stored through the battery. Because the output current is unstable, the stored power is unstable, and stroboscopic and stroboscopic Radiation, very unsuitable for high-use eye environment. Not recommended for use in the case of electricity.
