  • Zener diodes 54 and 55 and a resistor 56 serve as a voltage limiter.
  • a resistor 57 serves to establish an operating point of the field effect transistor 52.
  • a light-emitting diode 58 with a series resistor 59 provides optical information as to whether the circuit is operating correctly.
  • a fuse 60 arranged near the field effect transistor 52 interrupts the current supply in the event of overheating of the field effect transistor 52, so that a thermal fuse is provided.
  • FIG. 3 shows a further arrangement for energy-saving operation of a T5 fluorescent tube, in contrast to the arrangement according to FIG. 1 between the arranged on the first adapter adapter 9 electronic circuitry 38 and arranged on the second adapter adapter 11 electronic ballast 16 no optical signal transmission path is formed.
  • the task of the electronic circuit 38 in the first adapter adapter 9 to supply the second heating coil 33 of the T5 fluorescent tube 1 in case of need with a heating current is met by an electronic circuit arrangement, for which in FIG. 4 an embodiment is shown.
  • FIG. 4 shows an embodiment of the for use in the arrangement according to FIG. 3 provided electronic circuitry 38 in detail. Same reference numerals in the FIGS. 4 and 2 denote the same characteristics.
  • a capacitor 61 is arranged parallel to the second coil 43.
  • a parallel resonant circuit is formed, which is tuned so that between a point 62 and a point 63, a maximum voltage amplitude occurs at the high frequency of the lamp current at which the T5 fluorescent tube 1 generates a maximum amount of light.
  • the frequency for operating the t5 fluorescent tube is further increased. In such a case, the voltage amplitude occurring between the points 62 and 63 decreases.
  • This voltage amplitude affects the voltage difference between the gate and source of the field effect transistor 52.
  • the parallel resonant circuit formed by the second coil 43 and the capacitor 61 thus replaces the function of the photosensitive photodiode 51 of the circuit FIG. 2 .
  • the electronic circuitry of the FIG. 4 Diodes 64 and 65, which prevent flow back. Otherwise, the operation of the electronic circuitry of the FIG. 4 identical to the above FIG. 2 described electronic circuitry.
  • a low frequency current (50 Hz mains current) flows through the half coils 41 and 42 and the second filament 33, which is connected to the terminals 36 and 37.
  • a high-frequency current flows through one of the two half-coils 41, 42.
  • the charging capacitor 45 is charged, and the voltage applied to the charging capacitor 45 Voltage is smoothed by means of the resistor 46 and the capacitor 47.
  • the capacitor 47 also serves for time delay.
  • the voltage induced in the parallel resonance circuit causes a positive voltage difference between the gate and the source of the field effect transistor 52.
  • the field effect transistor 52 is turned on and closes via the bridge rectifier 53, the second filament 33 (in FIG. 4 not shown) between the terminals 36 and 37 short. In the switched-through state of the field effect transistor 52, therefore, no heating current flows through the second filament 33 connected to the terminals 36 and 37.
  • the frequency with which the T5 fluorescent tube is operated is increased. This reduces the voltage induced in the resonant circuit. A decrease in the induced voltage at the same time causes a reduction in the voltage difference between the gate and the source of the field effect transistor 52. If the voltage difference between the gate and source decreases, the field effect transistor 52 begins to block. In this case, the second filament 33 (in FIG. 4 not shown) is no longer short-circuited via the bridge rectifier 53, so that again a heating current through the connected to the terminals 36 and 37 second filament 33 can flow.
  • the branch with the field effect transistor can be assigned a resistance value which is of the order of the resistance value of the incandescent filament. Thus, part of the current flows through the FET and part through the filament. The heating current flowing through the second incandescent filament 33 is thus inversely proportional to the current flowing through the field effect transistor 52.
