Abstract: The invention relates to a switching regulator for operating luminaires, comprising a control circuit (4). The control circuit (4) is designed to operate, by triggering the switch (5) that is coupled to a coil, the switching regulator (3) in a limit mode of operation when the load generated by the luminaire (2) is so high that the resulting switching-off threshold exceeds a predefined minimum switching-off value, and operate the switching regulator in a discontinuous mode of operation at the minimum switching-off value when the load generated by the luminaire (2) is so low that the switching-off threshold in a limit mode of operation would lie below the predefined minimum switching-off value. The signal representing the current is fed to the control circuit (4) in both the limit mode of operation and the discontinuous mode of operation without being subjected to any external mean value generation.

Abstract: The invention relates to a method for testing whether at least two gas discharge lamps (L1, L2) to be operated with an electronic ballast (V) are the same type. The coil voltage and the coil current of each hot coil (W1b, W2b) of each gas discharge lamp (L1, L2) is measured in relation to a first time point and the coil resistances (R1cold, R2cold) are calculated therefrom. The absolute differential resistance (IRdiff I) is then calculated from both coil resistances (R1cold, R2cold). This is compared to a higher and a lower reference value (Ref1, Ref2), said comparison providing an indication as to whether both of the gas discharge lamps (L1, L2) are the same type.

Abstract: The invention relates to a method for allocating an operating address to an operating device for luminous means, in which the operating address is transmitted to the operating device in digitally coded form via an interface which is configured to connect a light sensor. The operating address is allocated by a user using a handheld device to transmit optical digital signals to a light sensor or infrared sensor which is connected to the interface.

Abstract: The invention relates to a method for activating at least one LED, which is supplied with a direct current voltage or a rectified alternating current voltage and which by means of a coil (L1) and a first switch (S1) clocked by a control/regulating unit (SR) provides a supply voltage for at least one LED, wherein when the first switch (S1) is switched on the coil (L1) temporarily stores energy that discharges via a diode (D1) and at least one LED when the first switch (S1) is switched off and wherein the control unit (SR) activates the first switch (S1) by means of a dimming signal. Said method is characterised in that the dimming signal is generated by externally combining a low-frequency signal and a high-frequency signal, wherein the pulse width (TON*LF) of the low-frequency signal is selected as an integral multiple of the cycle duration of the high-frequency signal.
