Zusammenfassung:To provide a lighting device with a deactivation function capable of adding the deactivation function while having a device scale equivalent to that of a conventional lighting device.SOLUTION: A lighting device with a deactivation function includes a UVC light source that emits ultraviolet rays having a peak wavelength in the wavelength range of 200 nm to 230 nm, an LED light source that emits visible light, a single AC/DC converter that converts the AC voltage derived from an external power supply to a DC voltage and outputs the voltage, a UVC light source circuit that converts the DC voltage output from the AC/DC converter into a voltage for lighting the UVC light source, and an LED light source circuit that converts the DC voltage output from the AC/DC converter into an LED light source lighting current.SELECTED DRAWING: Figure 5 【課題】従来の照明装置と同等の装置規模でありながらも、不活化機能を付加することのできる、不活化機能付き照明装置を提供する。【解決手段】不活化機能付き照明装置は、200nm~230nmの波長域にピーク波長を有する紫外線を出射するUVC光源と、可視光を出射するLED光源と、外部電源に由来する交流電圧を直流電圧に変換して出力する単一のAC/DCコンバータと、AC/DCコンバータから出力された直流電圧をUVC光源の点灯用電圧に変換するUVC光源用回路部と、AC/DCコンバータから出力された直流電圧をLED光源の点灯用電流に変換するLED光源用回路部とを備える。【選択図】図5
