    Abstract: A pre-conditioner circuit comprising first and second pre-conditioner modules (10, 12), each having an input (Vin1, Vin2) and an output (Vout1, Vout2), the outputs (Vout1, Vout2) being coupled to respective load modules (14, 16). The output (Vout1, Vout2) of each pre-conditioner module (10, 12) is serially connected to the input (Vin2, Vin1) of the other pre-conditioner module (12, 10), such that an arbitrary series of parallel connection of the load modules (14, 16) can be achieved, depending on the rout voltage (Vin). Thus, low voltage components can be used in pre-conditioner modules (10, 12) and the load modules (14, 16), without the need for over-dimensioning.

    Abstract: The invention relates to an electronic circuit and to a method of operating a high-pressure lamp in various operational modes. The circuit comprises a DC-AC converter consisting of two bridges (110-1) and (110-2). A series circuit comprising a first coil L1, the high-pressure lamp (120), and a second coil L2 is connected between the outputs (112-1) and (112-2) of these two half bridges. The invention has for its obeject to develop such a known circuit further such that it is equally suitable for an ignition mode and for a normal operational mode of the high-pressure lamp, without individual components having to be overdimensioned. According to the invention, this object is achieved in that a first capacitor C1 is connected in a path from the junction point of the first coil L1 and the high-pressure lamp (120) either to a reference potential (-) or to an operating potential (+), and in that a second capacitor C2 is connected in the path from the junction point of the high-pressure lamp (120) and the second coil L2 either to the reference potential (-) or to the operating potential (+) or in parallel to the high-pressure lamp (120).

    Abstract: A system (100) for controlling a plurality of light sources (104a-f) by means of light groups, wherein each light group synchronously controls a subset of the plurality of light sources. The system (100) comprises: a central controller (102); a plurality of light sources (104a-f) wired to the central controller (102); and a light sensor (106a-c) wired to the central controller (102). The central controller (102) is configured to: receive a measurement signal from the light sensor; based on the received measurement signal, determine a subset of light sources that are in optical contact with the light sensor; and include the subset of light sources in a light group associated with the light sensor.
