Abstract

蛍光管と反射板とを有する照明装置に取り付けられ、蛍光管の内部を流れる交流電流が発生する磁界から電磁誘導によって電力を取得する電力取得装置であって、電力取得装置は、前記蛍光管を取り囲むように取り付けられると共に、蛍光管の表面から垂直な方向の厚さと、蛍光管の長さ方向に平行な方向の長さとの少なくとも一方が一様でない。蛍光管の表面に垂直な方向に反射板が存在する領域を第１領域とし、蛍光管の表面に垂直な方向に前記反射板が存在しない領域を第２領域としたとき、第１の領域と第２の領域とで、蛍光管の表面から垂直な方向の厚さと、蛍光管の長さ方向に平行な方向の長さとの少なくとも一方が一様でないようにする。
