  • LIGHTING DEVICE WITH INACTIVATION FUNCTION
    Publication number: 20240148931
    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.

  • Wireless apparatus, wireless communication system, control method, and control program
    Patent number: 8116688
    Abstract: A wireless apparatus which can realize a DFS function that avoidance of interference with radar is considered in an Ad-Hoc mode under a multihop circumstance is provided. A Beacon frame is transmitted at a shorter interval than a previously set interval when radar is detected by wireless apparatuses N1 to N6 which have a DFS function which perform avoidance of interference with radar.
