OPTOELECTRONIC LIGHTING DEVICE AND METHOD FOR CONTROLLING AN OPTOELECTRONIC LIGHTING DEVICE

摘要

An optoelectronic lighting device comprises a plurality of optoelectronic semiconductor components (11, 12, 13), each of which are designed to generate light of a specific color, and a control unit (15) for controlling the current flow through the optoelectronic semiconductor component (11, 12, 13), wherein the control unit (15) generates a current through the optoelectronic semiconductor component (11, 12, 13) in order to generate a desired optical output power of one of the optoelectronic semiconductor components (11, 12, 13), which current corresponds to the quotient of the desired optical output power and the voltage dropping across the optoelectronic semiconductor component (11, 12, 13) multiplied by a predefined factor 1/η and added to a defined current value I _Offset, and wherein the values for η and I _Offset depend on the color of the light generated by the optoelectronic semiconductor component (11, 12, 13).
