The LED reading light, in particular for a passenger transportation vehicle such as, for example, an airplane, a bus, or a ship, is provided with two power supply connections (17) for connection to a power supply unit (16), an LED light means for giving off light with a desired light intensity, and a coding component (14), in particular a coding resistor, which is connected to at least one of the power supply connections (17), where the electrical parameter of the coding component (14) specifies the magnitude of a power supply current which can be provided for the LED light means by the power supply unit (16). Furthermore, the LED reading light is provided with a current controller (18) which is connected between the coding component (14) and the LED light means (12) and provides an operating current for the operation of the LED light means (12). The coding component (14) exhibits the electrical parameter for the provision of the maximum possible power supply current and the current controller (18) adjusts the operating current to a value at which the LED light means (12) gives off light with the desired light intensity.
