<p>[Problems to be solved] To solve a problem that introducing electric appliances such as a transmitter for transmitting micro radio waves such as Bluetooth and RFID, a transmitter for transmitting infrared rays, and a camera for capturing an image into an in-house requires a high cost. [Means to solve the problems] Energy is acquired from a magnetic field that is generated by a current for turning on a fluorescent lamp of a lighting equipment so as to drive the electric appliances such as a transmitter for transmitting micro radio waves such as Bluetooth and RFID, a transmitter for transmitting infrared rays, and a camera for capturing an image.</p> |
