Most common power failure lights and emergency lights are low-power embedded, portable, and hanging. Due to the limited range of lighting angles, it is not easy to turn off the power when the hanging is too high, and some still cannot. It is even more inconvenient to turn it off until the storage current is exhausted. It is a common product that only lights up when the power is off, but fails when it is really needed. Often it is not known that it is a problem with the lamp or the storage device, so it cannot be used.

Therefore, whether it is an emergency lighting application regulated by laws and regulations, or the efficacy of automatic discharge maintenance lighting, its structural design, lighting and durability are the most important, and the storage capacity of the power storage device depends on the light emitted by the lighting device. One of the keys to time, if due to the above-mentioned lacks, coupled with lack of charging, inaccurate detection, and formalization, each power-off device becomes useless, thus losing the meaning of emergency lighting settings, and it may also be due to The lack of lighting will cause troubles for people to escape, and even loss of life and property.
