    Abstract: A fluorescent lamp (2), in particular a backlight lamp of a display device, is supplied with an alternating voltage, a frequency and an amplitude of which being greater during ignition than during normal operation of the lamp. The voltage (V) across the lamp and the current (I) through the lamp are measured to provide a measured voltage value and a measured real lamp current value. From the alternating voltage there is derived a voltage (V2). The measured voltage value is multiplied by the sum of the measured real lamp current value and the derived voltage. The multiplication result (P=V*(I+V2)) is compared with a reference value (Ref), which results in a difference or error value. The error value is used to control the frequency and the amplitude of the alternating voltage (V), such that the error value is minimized.

    Abstract: A method for bonding a lighting device to a first lighting system, in which the first system comprises a master controller, which is remote from the lighting device and which may control a slave controller of the lighting device if the slave controller has stored therein an identification (ID) of the system. Upon powering up, if the slave controller contains such an ID, it tries to communicate with a master controller of the system. If the slave controller does not succeed in establishing such a communication it enters a state in which it can change it settings, in particular clearing said ID, upon receiving, during a time window with reduced communication security level, a message for allowing such changing of its settings.

    Abstract: In a digital interface comprising a current limiter, a reference voltage proportional to the bus voltage is generated and the current limiter is switched on when the incoming digital signal is higher than the reference voltage and switched of when the incoming signal is smaller than the reference voltage. The “high/low-ratio” of the digital signal at the output of the interface is substantially improved by the use of the reference voltage.
