Abstract
Provided is a lighting device with an inactivation function, the lighting device allowing the addition of an inactivation function while being equal to conventional lighting devices in device size. The lighting device with the inactivation function includes: a UVC light source to emit ultraviolet light having a peak wavelength in a wavelength range from 200 nm to 230 nm; an LED light source to emit visible light; a single unit of an AC/DC converter to convert an AC voltage derived from an external power source into a DC voltage and output the DC voltage; a UVC light source-specific circuit part to convert the DC voltage output from the AC/DC converter into a voltage for lighting the UVC light source; and an LED light source-specific circuit part to convert the DC voltage output from the AC/DC converter into a current for lighting the LED light source.
