A converter (10) for supplying current to a light emitting means (9) has an input (11, 12) configured to receive a direct current supply voltage. The converter (10) has at least one controllable switch (21, 22; 41-44) coupled to the input (11, 12). The converter (10) has a first diode (14) and a second diode (15) connected in series. The converter (10) has an inductor (13) having a terminal coupled to the at least one controllable switch (21, 22; 41-44) and another terminal coupled to an anode of the first diode (14) and a cathode of the second diode (15). |
