EMERGENCY LIGHTING EQUIPMENT

To provide an emergency lighting device capable of sufficiently securing a lighting time at an emergency lighting at the same time of performing an activation of a battery by a discharge.SOLUTION: An emergency lighting device of the present disclosure, comprises: a light source part; a battery that supplies a power to the light source part; a normal power supply circuit that charges the battery by an external power supply; an emergency power supply circuit that makes the light source part turn on by the power of the battery; and a control part that executes an activation processing of the battery by controlling the normal power supply circuit and the emergency power supply circuit. The activation processing is a processing for repeatedly and alternately executing a first discharge processing and a second charging processing after a first charging processing. The first charging processing is a charging processing for charging a regulation battery capacity. The first discharge processing is a discharging processing for remaining the regulation battery capacity. The regulation battery capacity is a battery capacity that can light the light source part for a time longer than a regulation time as a predetermined emergency lighting time.SELECTED DRAWING: Figure 2 【課題】本開示は非常用照明装置に関し、放電による電池の活性化を行うと同時に、非常点灯時の点灯時間を十分に確保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、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、電池の活性化処理を実施する制御部とを備える。活性化処理は、第一の充電処理の後、第一の放電処理と第二の充電処理を交互に繰り返し実施する処理であり、第一の充電処理は、規定電池容量を充電させる充電処理であり、第一の放電処理は、規定電池容量を残存させる放電処理であり、規定電池容量は、予め設定された非常点灯時間である規定時間よりも長く光源部を点灯できる電池容量である。【選択図】図２
