Electromagnetic interference reducing device for fluorescent illumination device, such as fluorescent tube, has capacitor element for conducting HF energy from electronic ballast unit to ground potential

摘要

The electromagnetic interference reducing device has capacitor elements (22a-22c) for conducting high frequency (HF) energy from an electronic ballast unit (14) to ground potential (10). The electronic ballast unit controls illumination of a fluorescent tube (4) and is mechanically compatible to a starter unit of the fluorescent illumination device. The electronic ballast unit determines a connection position of a filter unit (16). Independent claims are also included for the following: (1) a fluorescent arrangement; a fluorescent illumination element; and (2) a method of reducing electromagnetic interference of a fluorescent illumination device.
