1. A LED assembly comprising:

  • a plurality of LEDs arranged in groups, each group comprising at least one LED,a control circuit for driving the LEDs, the control circuit comprising a sensing device for sensing an operative parameter of the LEDs,the control circuit being arranged to;

    a) operate at least one group of the LEDs;

    b) sense by the sensing device a value of the operative parameter of the at least one group;

    c) repeat a) and b) for at least a different one of the groups;

    d) assign to each of the groups of LEDs a value of the operative parameter from the sensed operative parameter values; and

    e) control the driving of the groups of LEDs from the assigned operative parameter values.
