Fire emergency light capable of automatically displaying battery faults

Abstract

The invention discloses a fire emergency light capable of automatically displaying battery faults. A left illuminating light and a right illuminating light are fixed to the top of a shell, a switch is installed in the middle of the top of the shell, a power indicator light, a charging indicator light and a fault indicator light are installed on the upper left corner of the obverse side of the shell, a fuse and an inspecting button are installed on the lower left corner of the obverse side of the shell, a circuit board is installed in the shell, and a battery is installed under the circuit board, wherein the battery is a chargeable battery, and the fault indicator light is a light emitting diode. According to the fire emergency light, by additionally arranging the circuit capable of automatically displaying the battery faults in the fire emergency light and installing the battery fault indicator light on the shell, the problem that for many fire emergency lights which are hung on the wall for several years, the conditions that the battery leaks liquid, a battery spring is rusted, and the battery is expanded and can not normally achieve charging and discharging can occur due to air humidity if the battery placing time is too long is solved, therefore, people can conveniently overhaul the fire emergency light in time and replace an aged and bad battery, and then the purpose that safety is weightier than the Mount Tai is achieved.

Description

technical field [0001] The invention relates to a fire-fighting facility, in particular to a fire-fighting emergency light which adds a circuit capable of automatically displaying battery failure in the fire-fighting emergency light and which is equipped with a battery failure indicator light on the casing. Background technique [0002] Fire emergency lights are a very important fire-fighting tool in our lives, especially in some high-rise buildings, shopping malls, entertainment venues and other crowded places. Many fire emergency lights are hung on the wall for several years. If the battery is left for too long due to air humidity, the battery will leak, the battery spring will be corroded, the battery itself will swell, and the battery will not be able to charge and discharge normally. If in case of special circumstances such as a power outage, the fire emergency light cannot work normally when it is most needed in an emergency. It usually uses an external power supply f...
