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 memory device can be read out by the same connectivity used for driving the luminaire, so that the driver can be informed about required operation conditions. The driver can thus learn about the service-related information before starting to drive the luminaire.

Method and system for supporting serviceability of luminaires

The invention is directed to electrical load grouping based on measurements of an electrical parameter at electrical load sensors (A,B). An electrical load grouping device () is configured for receiving a changed value of the electrical parameter from one or more of the electrical load sensors (A,B) in reaction to a changed power consumption of a respective electrical load (A, . . . ,C). The electrical load grouping device () is further configured for assigning the respective electrical load (A, . . . ,C) to a group (A,B) of electrical loads associated to an electrical load sensor (A,B) or groups of electrical loads associated to electrical load sensors based on which electrical load sensor (A,B) or which electrical load sensors measured the changed value of the electrical parameter received in reaction to the changed power consumption of the respective electrical load (A, . . . ,C).

Electrical load grouping

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.

Method and system for setting a driving current of luminaires
