Abstract: A method for operating an optoelectronic semiconductor device. The semiconductor device includes a first optoelectronic semiconductor chip for generating, for example, blue light, an optional second optoelectronic semiconductor chip for generating, for example, green light, and a third optoelectronic semiconductor chip for generating, for example, red light. The semiconductor device also includes a driver unit which supplies the semiconductor chips with current during operation. The third semiconductor chip is operated on the basis of a temperature-brightness characteristic curve stored in the driver unit. The temperature-brightness characteristic curve is configured for a minimum color location deviation over an intended operating temperature range, relative to at least one reference color location.
