Publication number: 20150380986Abstract: The system contains a first operation module connected to AC mains and a second operation module connected to a lighting device. The first operation module contains an activation switch, a first electricity detection unit, and a wireless transmitter. The second operation module contains a second electricity detection unit, a reset switch, and a wireless receiver. The first and second operation modules communicate through the wireless transmitter and receiver. When electricity provision is normal, the second operation module plays a dominant role in a wired mode. When the activation switch is engaged, the second operation module releases the dominant role to the first operation module, where the uninterruptible power supply system enters a wireless mode. To switch back to the wired mode, the second operation module is reset by the reset switch. The uninterruptible power supply system as such can be freely alternated between the wired and wireless modes.Type: ApplicationFiled: June 27, 2014Publication date: December 31, 2015Inventor: Ching-Nan Yang
