Embodiment Construction

[0021] It is convenient to note that the current and voltage levels indicated in this specification refer to their root mean square (rms) values. Thus, 1A means 1A rms current and 1V means 1V rms voltage.

[0022] It is also convenient to note that the terms 'rated power', 'rated current' or 'rated voltage' mean maximum operating power, current or voltage respectively.

[0023] figure 1 A schematic diagram of a CCR 10 according to the invention is depicted, with a power line input 11 for connection to the mains and a power output 12 for connection to a series connection 9 of lighting lamps. The series connection circuit 9 is generally constituted by series circuit transformers 92 whose primary coils are connected to the series connection circuit 9 and whose secondary coils are connected to the lamp 91 .

[0024] The CCR 10 is formed of modular units 13 - 1 , 13 - 2 to 13 - n hereinafter referred to as power modules 13 . The power modules 13 are connected to the power line i...

Abstract

Constant current regulator (10) for supplying a series circuit (9) of a lighting installation with an output electrical power corresponding to a predetermined output power, comprising a plurality of modules (13) electrically connectable for simultaneous operation to jointly provide the output power, the modules being each configured for providing a module output power contributing to the output power of the regulator. Each module comprises its proper transformer (135) for providing galvanic insulation as required by local standards, and a microcontroller (231) for controlling operation of the module. The constant current regulator comprises a data communication network (17) configured to be connected to the microcontrollers (231) of the modules (13), wherein the microcontrollers (231) are operable to exchange data over the data communication network (17) so as to make the constant current regulator (10) modular, meaning that one or more of such modules (13) can be added to or removed from the constant current regulator.

Description

technical field [0001] This invention relates to constant current regulators (CCRs), and more particularly to regulators for providing electrical power to airport lighting. Background technique [0002] A CCR of the above type is known, for example, from US 2010 / 283400. The purpose of the CCR is to regulate the current output level around an operating point which can be set by the operator or the airport control tower. The current output level should be as constant as possible around a preset operating point in order to ensure that the airfield lights emit light with a constant luminous intensity. Since it is desirable to use different intensities depending on the environment (eg, day or night, good or low visibility), the operating point may change and the CCR must be able to adapt the current output level accordingly. [0003] Airfield lights are often set up in long series connections. The length and number of lights in such a series and the power supplied to them can ...
