Abstract
【解決手段】照明装置1は、直管形の蛍光灯10と、2次電池11と、蛍光灯10を点灯する点灯回路部13と、信号線2を通して制御装置3から制御信号を受信したり、制御装置3に対して応答信号を送信する通信部14と、上流側並びに下流側の信号線2A,2Bが接続される通信端子台15とを備える。信号線2A,2Bは一対の信号線路2b,2cとシールド線2aを有する。2つの信号線2A,2Bのシールド線2aをコンデンサ16を介して接地したため、コンデンサ16によって2つの信号線2A,2Bを直流的に絶縁しつつ、接地電位を他の照明装置1と高周波的に揃えることができる。その結果、交流電源ACに放出される雑音端子電圧を低減することができる。
