Fluorescent tubes e.g. T-5 fluorescent tubes, operating system, has shielding module including output electrically connected with electronic ballast input and one input linked with one connector of respective end cap of tube

摘要

The system has an electronic ballast (8) with an input for supplying alternating current, and a high frequency output connected with respective connectors of two end caps of a fluorescent tube. A shielding module has an output, electrically connected with an input of the ballast. The input of the module is connected with one of the two connectors of one cap. Spiral wound filaments are attached to the connectors of the respective caps.
