Abstract: An assembly and a method is provided where the LED module includes a plurality of module units interconnected between common connection lines in a sequential order with increasing distances towards a connection terminal of the LED module. The circuit assembly includes an output terminal having a first output terminal portion and a second output terminal portion, a main power supply for supplying an operation voltage potential to a first output terminal portion, a control device for generating a pulse width modulation signal, and an electronic switch coupled to the control device and configured to obtain the pulse width modulation signal and arranged to connect and disconnect a second output terminal portion to/from a reference potential in accordance with the pulse width modulation signal, such as to supply a pulse width modulated voltage to the output terminal. A pulse shaping unit is coupled to the control device.
