Abstract: The aim of the invention is to determine an operating point (220) of an AC/DC converter and optionally of a DC/DC converter, fed by the AC/DC converter, for feeding an operating DC voltage into a luminaire bus system in such a way that a power loss (202) of the luminaire bus system is reduced. This aim is achieved according to the invention in that a plurality of calibration DC voltages (282) are sequentially fed into the luminaire bus system, and a corresponding power consumption of the luminaire bus system is determined for each calibration DC voltage (282). The operating point can then be determined based on the power consumptions.

Abstract: The invention relates a system for determining a change in a room (1). The invention comprises in particular a self-teaching illuminating system which detects a presence of an individual in an illuminated area. The system comprises lighting means (2) which output light, control means (3) which control the luminous output from the lighting means (2), measuring means (4) which determine a luminous intensity, and an evaluation means (6) which evaluates the luminous intensity determined by the measuring means (4). The evaluation means (6) is designed to detect a change of an object/individual in the room (1), starting from a determined luminous intensity at at least one first time, at which the lighting means (2) outputs no light, and a luminous intensity at at least one second time, at which the lighting means (2) outputs light.

Abstract: The invention relates to a clocked flyback converter circuit for directly operating lighting means comprising: a transformer (5), which has a primary winding (4), which is coupled to a controllable switch (7), and a secondary winding (6), to which the lighting means (11) can be coupled; a control unit (14) for controlling the switch (7); and means (8) for directly or indirectly sensing the current through the switch (7) in the switched-on state and for feeding a signal and reflecting said current to the control unit (14). The control unit (14) is designed to switch off the switch (7) if the signal reflecting the current has reached a variable switch-off threshold (Is), to change the switch-off threshold (Is) in order to change the power transmitted by the flyback converter circuit (3), and to reduce the switch-off threshold (Is) for the current signal only down to a minimum value and to switch from operation in the limit mode to discontinuous operation in order to achieve a further reduction in the power transmitted by the flyback converter circuit (3) while the switch-off threshold (Is) is fixed.
