Abstract: The invention relates to an incorporation of a current limiting/regulating circuit on a luminaire board for ensuring that the luminaire board will automatically operate at its desired current after a replacement. Since the current control at the luminaire board causes an initial mismatch between the current supply of the driver and the demand of the luminaire board, the driver output voltage will drift towards the maximum output voltage of the driver. When the maximum output voltage is reached, the driver is configured to operate in constant-voltage (CV) mode, sense the output current and reduce its output current to the same value as consumed by current-controlled luminaire board. Alternatively, the driver may gradually reduce the setpoint of the output current until it just leaves the CV mode and stay at that setpoint. In this way, the driver will automatically operate at the correct current of a newly installed luminaire board without any action from the user.

Abstract: The invention relates to an integration of a programmable memory device in a luminaire for storing service-related information such as drive parameters, repair history information and the like.

The driver can thus learn about the service-related information before starting to drive the luminaire.

A stored voltage-current profile of an initial powering phase of a powered device (22) is provided. A voltage level provided to the powered device (22) in a subsequent initial powering phase of the powered device (22) is adjusted as long as a value corresponding to a current voltage level of a voltage-current profile of the subsequent initial powering phase deviates less than a predetermined threshold level from its corresponding value of the stored voltage-current profile of the initial powering phase of the powered device (22) and until a predetermined voltage level is reached. This can allow detecting whether a previously connected powered device (22) was replaced by another powered device (22) and to immediately start-up an unchanged powered device (22) with previously used operation parameters.
