EMERGENCY LIGHTING DEVICE

To provide an emergency lighting device that can improve performance during emergency lighting by sufficiently activating the battery at the same time as inspecting it.SOLUTION: An emergency lighting device according to the present disclosure includes a light source unit, a battery that supplies power to the light source unit, a normal power supply circuit that charges the battery from an external power supply, an emergency power supply circuit that lights the light source unit with the power of the battery during a simulated power outage, and a control unit that performs a battery inspection process by controlling the normal power supply circuit and the emergency power supply circuit. The inspection process is performed from the start of the simulated power outage to its release, and includes a process of determining that the battery has reached the end of its life when the battery voltage reaches a battery life determination threshold before a specified time has elapsed since the start of the simulated power outage, a process of determining that the battery is normal when the battery voltage does not reach the battery life determination threshold before a specified time has elapsed since the start of the simulated power outage, and a process of releasing the simulated power outage after the battery voltage reaches the battery life determination threshold.SELECTED DRAWING: Figure 2 【課題】本開示は非常用照明装置に関し、点検と同時に電池の活性化を十分に行うことで、非常点灯時のパフォーマンスを改善できる非常用照明装置を提供することを目的とする。【解決手段】本開示の非常用照明装置は、光源部と、光源部に電力を供給する電池と、電池を、外部電源により充電するための常用電源回路と、疑似停電時に電池の電力により光源部を点灯させる非常用電源回路と、常用電源回路及び非常用電源回路を制御することで、電池の点検処理を実施する制御部とを備える。点検処理は、疑似停電の開始から解除まで実施され、疑似停電の開始から規定時間が経過する前に、電池電圧が電池寿命判定閾値に達した場合、電池が寿命であると判断する処理と、疑似停電の開始から規定時間が経過する前に、電池電圧が電池寿命判定閾値に達しなかった場合、電池が正常であると判断する処理と、電池電圧が電池寿命判定閾値に達した後に、疑似停電の解除を実施する処理とを含む。【選択図】図２
