Abstract
An LED reading light, in particular for a passenger transport vehicle, such as an aircraft, a road vehicle, a ship or a rail car, is disclosed that has a plurality of illuminating LED's and in operation provides a desired light intensity for a set supply current, wherein the LED reading light comprises two power supply terminals connectable to a power supply for receiving the set supply current, and at least one lighting strand coupled between the two power supply terminals. Each of the at least one lighting strand comprises at least one voltage drop diode, with the at least one voltage drop diode in operation not contributing to the desired light intensity, and at least one of the illuminating LED's. The illuminating LED's are distributed among the at least one lighting strand and connected such that they jointly provide the desired light intensity for the set supply current.
