具有放电灯的照明装置
摘要：
本发明的放电灯具有：多个放电灯；照度检测部，其检测从多个放电灯照射的照明光的照度；以及照度控制部，其根据检测出的放电灯的照度，调整针对多个放电灯的输入电力，照度控制部针对多个放电灯中的、具有超过了根据基准照度值而确定的允许阈值的照度值的放电灯，以使照度朝向在允许阈值与基准照度值之间确定的鲁棒阈值而变化的方式进行电力调整。
摘要（英）：

This discharge lamp is provided with: a plurality of discharge lamps; a plurality of illuminance detection units that detect the illuminance of illuminating light irradiated by the plurality of discharge lamps; and an illuminance control unit that adjusts the input electric power for the plurality of discharge lamps on the basis of the discharge lamp illuminance that is detected. The illuminance control unit adjusts the electric power such that illuminance changes for discharge lamps having illuminance values that exceed an allowable threshold value determined on the basis of a reference illuminance value, out of the plurality of discharge lamps, toward a robust threshold value determined between the allowable threshold value and the reference illuminance value.
