Description

technical field [0001] The invention relates to a lighting device, in particular to an emergency lighting device. Background technique [0002] In emergency lighting equipment, due to the low voltage of the battery, the mains power needs to be rectified and lowered before charging, which is quite complicated. When the battery is used in uninterruptible power supply equipment, the electric energy provided by the battery needs to be converted and boosted to supply power to the load, which is not conducive to timely response in emergency situations. In addition, batteries use chemical reactions to store and release electrical energy, and their energy storage density is low, and their energy storage characteristics deteriorate over time. In addition, the battery also has certain requirements on the environmental conditions. For example, an increase in the ambient temperature will increase the chemical activity inside the battery, thereby shortening the life of the battery, and ...

Problems solved by technology

In addition, the storage battery uses chemical reactions to store and release electrical energy, its energy storage density is small, and its energy storage characteristics deteriorate over time

In addition, the battery also has certain requirements on the environmental conditions. For example, an increase in the ambient temperature will lead to an increase in the internal chemical activity of the battery, thereby shortening the life of the battery, and there may also be chemical liquid leakage, which may cause safety hazards.

[0003] Due to the above-mentioned shortcomings, some people in the industry use magnetic capacitor batteries to replace traditional storage batteries. Magnetic capacitor batteries have wide-voltage charging and discharging characteristics, thereby simplifying the charging and discharging process and improving equipment use efficiency. However, this improvement is only The way of storing the electric capacity of the battery is changed, and the circuit is not improved. Therefore, even if the electric capacity in the rechargeable battery has reached saturation, the current still flows through the rechargeable battery all the time. Damage the rechargeable battery and reduce the service life of the rechargeable battery
