PURPOSE:To decrease the intensity of an electric field within the restriction of the law and prevent an evil influence such as radio wave trouble by making the length of a lead line as short as possible and wiring it in close contact with a fluorescent discharge tube. CONSTITUTION:The major part of a fluorescent lamp 21 is covered with a lamp heater 25 except a part where the light is emitted, and clamps 26 and 27 for fixing the heater 25 to the fluorescent lamp 21 are provided. A heat-resisting cable 24 is brought into contact with the heater 25 by cable stoppers 30 and 31 to reduce the thin and long rectangular area formed of the fluorescent lamp 21, sockets 22 and 23, and cable 24 as much as possible, decreasing the intensity of the electric field produced by this fluorescent discharging device. Thus, an evil influence such as radio wave trouble is prevented. |
