Beschreibung
Zusammenfassung:	The utility model relates to the technical field of LED illumination, and discloses an LED light source configuration circuit, an LED drive circuit and an LED lamp. The LED light source configuration circuit comprises a first lamp set, a second lamp set and a switching device, the switching device is connected with the input end and the output end of the first lamp set and the input end and the output end of the second lamp set, and the output end of the first lamp set and the input end of the second lamp set are connected so that the first lamp set and the second lamp set can be connected in series. Or the input end of the first lamp group and the input end of the second lamp group are connected, and the output end of the first lamp group and the output end of the second lamp group are connected, so that the first lamp group and the second lamp group are connected in parallel. The embodiment of the utility model can be adapted to at least two driving voltages, and the phenomenon that the driving voltages are
