Definitions

  • the invention relates to operating devices for lighting means and methods for suppressing glowing of a lighting means.
  • the invention relates in particular to operating devices and methods in which the operating device has a radio interference suppression element.
  • Energy-saving lights can use light-emitting diodes (LEDs) as light sources. Such lamps can also be excited to glow by small currents. When using lights with light-emitting diodes as a light source, the effect can occur that the light is still lit when it is switched off. This effect can occur, for example, as so-called ghost light after the lamp has been switched off. In general, the lighting of the lamp when it is switched off is referred to here as glowing.
  • One cause of such a glow can be, for example, line capacitances or a capacitive coupling within the operating device, but also other capacitive or inductive couplings. From the pamphlet US20070267984 a capacitance as a radio interference element between the primary side and the secondary side of an operating device is already known.
  • the object of the invention is to provide an operating device for a lamp and a method with which the glow of a lamp can be effectively suppressed, i.e. reduced, when the lamp is in a switched-off state.

Since the anti-glow device is provided in the operating device for the lighting means, the use of a separate unit for residual light suppression, which is connected, for example, between the operating device and the lighting means, is no longer necessary. Accordingly, the losses that can be caused by such a separate unit between the operating device and the lighting means can also be avoided.
