Abstract

In various embodiments, an optoelectronic component device is provided. The optoelectronic component device may include a linear regulator designed for providing an electric current; an optoelectronic component formed for converting the electric current into an electromagnetic radiation; and an electrothermal transducer designed for converting the electric current into a temperature difference. The electrothermal transducer is thermally coupled to the optoelectronic component, and the optoelectronic component and the electrothermal transducer are electrically coupled in series with the linear regulator.
