Patent ID: 8446100

Claim:
An interconnected arrangement of at least two light-emitting diode chip arrangements having individual modules as luminous elements in a parallel circuit, wherein each of said individual modules is provided with at least one light-emitting diode chip, and said modules are arranged in a parallel circuit, said arrangement further comprising: a single, common, current-carrying voltage source; and a respective linear constant current circuit for each of said light-emitting diode chip arrangements, wherein each of said light-emitting diode chip arrangements is connected to said common, current-carrying voltage source via said constant current circuit, further wherein said common voltage source is configured to provide to each of said constant current circuits the same voltage, further wherein at the start of an operation said voltage source continuously increases a supply voltage over an operating range assigned to said voltage source, and wherein when a constant total current flowing over the parallel circuit is reached, said common, current-carrying voltage source fixes the associated supply voltage and maintains said supply voltage unaltered, wherein if the total current that is supplied drops by a preset value at said common, current-carrying voltage source, said voltage source is configured to switch off and to immediately again increase the supply voltage over the operating range of said voltage source.
