Abstract:
A dimmable LED reading light unit, in particular for a passenger transportation vehicle, such as an airplane, a bus or a ship, comprises an input which is connectable to a potentiometer that outputs a direct voltage having a voltage intensity corresponding to a selected potentiometer position; a load current source being configured to generate a predetermined load current; a current controller providing an operating current for operating at least one LED; and an electronic measuring and control unit; wherein the load current source and the current controller are connected to the input in parallel.
