Patent number: 8884786Abstract: The invention relates to a light sign (10) for displaying an instruction and/or guidance for ground airplane traffic at an airport, comprising a casing (20) with a transparent display panel (21) for representing an instruction and/or guidance symbol (Z), and a light source arranged inside the casing (20) with at least one luminescent diode (32) for illuminating the display panel (21). A diffusion panel (22) is made for scattering and/or back-scattering incident light, wherein the light source is arranged between the display panel and the diffusion panel. The at least one luminescent diode (32) is aligned on the diffusion panel (22) so that the display panel (21) is not illuminated directly, but indirectly by back-scattering of the light emitted from the at least one luminescent diode by the diffusion panel (22).Type: GrantFiled: April 30, 2010Date of Patent: November 11, 2014Assignee: ADB BVBAInventors: Martijn Beukema, Pierre Tremouroux

Patent number: 8651686Abstract: The invention relates to a lighting unit for lighting airfields on an airport, in particular for delivering signals to an airplane. It comprises a light source, which has at least one light-emitting diode for generating light to be emitted, electrical components for supplying and actuating the light source, optical components for influencing the light generated by the light source, and an outer housing for receiving the light source and the electrical and optical components, which has a light exit opening through which light influenced by the optical components exits. According to the invention, the light source is arranged with the electrical and optical components in a cassette module closed in a gas-tight manner. Said module is integrated in the outer housing, wherein the outer housing is likewise closed in a gas-tight manner, so that the components disposed in the cassette module have double sealing protection.Type: GrantFiled: September 30, 2010Date of Patent: February 18, 2014Assignee: ADB BVBAInventors: Martijn Beukema, Ludo Moons

Patent number: 8284751Abstract: The invention relates to a communications system for airport signalling devices. In said system, the series or parallel circuits used for supplying electricity to the signalling devices are used for the communication between a control device, a central communication device and signalling devices. The OFDM method is preferably used to transmit signals and decentralised communications devices, which are assigned to the signalling devices and preferably have elements for preparing the signals, are dynamically configured in an adaptive manner during the active operation of the system by a central communication device.Type: GrantFiled: July 17, 2003Date of Patent: October 9, 2012Assignee: ADB BVBAInventor: Klaus Kock

Patent number: 8138683Abstract: Disclosed is a method for controlling a series circuit current of a lighting installation at an airfield or the like, in which case the series circuit current which flows through transformers which are arranged on the secondary side of an output transformer and are connected in series, in order to supply lighting appliances is controlled by means of a thyristor module, which is arranged on the primary side of the output transformer and has a variable trigger angle, in which case, when a control unit is in a constant-current mode, the trigger angle is set in such a manner that a series circuit current which corresponds essentially to a rated output current flows. The invention also relates to a constant-current regulator for carrying out the method.Type: GrantFiled: October 9, 2006Date of Patent: March 20, 2012Assignee: ADB BVBAInventors: Pierre Catoul, Daniel Tessens, Jean-Claude Vandevoorde
