Patent ID: 7157860

Claim:
A control device for a flashlight system at an airport, comprising; flashlight units, connected on an input side to a power supply line and each respectively connected on an output side to a respective flash lamp of the flashlight system via a lamp cable, each of the flashlight units including; a printed circuit board (PCB), including a circuit to control the respective flash lamp and a power-integrating low-voltage capacitor; a local master controller; and a field bus system, by which the local master controller is connected to the flashlight units, wherein the power-integrating low-voltage capacitors are, supplied with power by a power factor-corrected power source connected to the flash lamps, wherein the power transferred to the flash lamps is electronically controlled to regulate luminous intensity and to stabilize the luminous intensity with respect to voltage-source and line-impedance fluctuations, and wherein at least one of simultaneous and mixed flashlight configuration patterns is realized.
