  • Patent number: 7157860
    Abstract: A control for a flashlight system in an airport, includes flash units which are connected to an energy supply line and, on the output side, to respective flashlights of the flashlight system via a light cable. In order to avoid unwanted high voltages, each flash light unit includes an energy-integrating low-voltage capacitor which can be supplied by a current source having a corrected power factor and which is connected to the flashlights embodied as low-voltage lights. The energy transmitted to the flashlights can be electronically controlled. A connection device connecting the flash units to a local master control system is embodied as a local field bus system, in such a way that different, conventionally arranged, simultaneous or mixed flash configuration patterns can be produced by way of the same electrical installation.

  • Publication number: 20050017659
    Abstract: A control device is for flashlight systems in airports. The control device includes flash units which are connected, on the input side, to an energy supply line and, on the output side, to respectively one flashlight of the flashlight system via a light cable. The flash units respectively include a PCB (printed circuit board) for controlling the flashlight, a local master control system, and a connection device by which the local master control system is connected to the flash units. In order to avoid unwanted high voltages, each flash light unit includes an energy-integrating low-voltage capacitor which can be supplied by a current source having a corrected power factor and being connected to the flashlights embodied as low-voltage lights. The energy transmitted to the flashlights can be electronically controlled in order to regulate the light intensity and to stabilize the same against voltage source variations and power impedance variations.
