Abstract
An LED array has a plurality of LED chains, which each have at least one LED and are connected in parallel. The LED array has at least one output for feeding back radiation generated to a power supply unit. Preferably, at least one reference LED chain is connected in parallel with the LED chains and a photosensitive component is provided, the photosensitive component detecting the radiation emitted by the reference LED chain. The photosensitive component generates a measurement signal in a manner dependent on the radiation generated by the reference LED chain, which signal serves for providing feedback to the power supply unit.
