Abstract (en)
[origin: US2009051301A1] An interconnected arrangement of a light-emitting diode chip arrangement having individual modules as luminous elements in a parallel circuit. Each module is provided with at least one light-emitting diode chip, and the modules are arranged in a parallel circuit. A respective linear constant current circuit connects each light-emitting diode chip arrangement to a common, current-carrying voltage source. At the start of an operation, the voltage source continuously increases the supply voltage over an operating range assigned to it. When a constant total current flowing over the parallel circuit is reached, the current-carrying voltage source fixes the associated supply voltage and maintains it unaltered.
