Zusammenfassung:LED light source, comprising a series connection of at least two LED strings, wherein each of the at least two LED strings corresponds to a single LED or comprises at least two LEDs, wherein at least one ohmic resistive element is connected in series with a first LED string of the at least two LED strings, and at least one switching element is connected in parallel to the series connection of the at least one ohmic resistive element and the first LED string, wherein the at least one switching element is configured to bypass in its conductive state the series connection of the at least one ohmic resistive element and the first LED string.
