Definitions

  • the interface device can have at least one switch which switches the respective signal path to the associated input port of the control device.
  • a switch can be self-controlled, as in the described example of the zener diode. It is also possible to use a switch with a control input, which can be controlled in particular via the external control input signal of the interface device or via a signal derived therefrom.
  • a switch 60 connected to mains voltage N, L, external control signals are generated, i. for the duration of the closing of the switch 60, a sinusoidal mains current is emitted.
  • a push-button instead of a switch, a push-button may be used, and the push-button or switch may also switch another voltage such as a constant voltage.
  • the external control signal generated in this way is generally used in the electronic ballast according to the invention in those cases in which the electronic ballast is used as an independent light control device.
  • the supplied external control signals are interpreted by the microcontroller 30 as brightness control information, for example for switching on or off or for dimming the lamp.
  • the transistor 79 is turned on, whereby the transistor 71 blocks, so that the first-described signal path is interrupted is. If the external control signal has a sequence of rectangular voltage pulses with an amplitude which is greater than the threshold voltage of the zener diode 80, it is ensured at any time that only one of the two described signal paths to the input port 32 or to the input port 31 is opened.
  • an external digital control signal for example a DALI signal
  • the zener diode 80 blocks the non-normally-off switch 90 because the capacitor C1 initially has no voltage.
  • the bridge rectifier 70 outputs an average positive voltage at which the capacitor C1 is charged. After the voltage across the capacitor has been reached in order to drive the transistor 90 for conduction, the signal path for the digital signal is enabled, ie opened, and thus lies against the input port 31 of the microcontroller 30.
