Modular lighting application

A modular system comprising a first component comprising an LED driver and a second component comprising a light engine,

• the LED driver comprising:
• a switched mode power converter configured to output a supply current;
• a first control unit configured to control a switch of the switched mode power converter, thereby controlling the supply current;
• the light engine comprising:
• an LED assembly configured to receive the supply current, the LED assembly comprising a plurality of LEDs or LED groups and one or more switches arranged in series or in parallel with one or more LEDs or LED groups of the plurality of LEDs of LED groups, and
• a second control unit configured to control the one or more switches of the LED assembly, thereby controlling a supply of the supply current to the plurality of LEDs or LED groups of the LED assembly;
• wherein the first control unit and the second control unit are configured to co-operate and control the supply current and the supply of the supply current to the LED assembly in accordance with a desired illumination characteristic, and wherein the first and second control unit are configured to synchronize a switching operation of the switch of the switched mode power converter with a switching operation of the one or more switches of the light engine,
• wherein the first control unit and the second control unit are configured to control the LED assembly to generate a desired illumination characteristic by controlling the switch and the one or more switches within a predetermined modulation time window and
• wherein the first control unit and the second control unit are configured to synchronize the switching operation of the switch of the switched mode power converter with the switching operation of the one or more switches of the light engine by receiving a common clock signal or by exchanging a synchronization signal.
