Abstract

An optoelectronic device for emitting electromagnetic radiation with a controllable emission intensity comprises, at least one optoelectronic component (100) which is adapted for generating, in operation, electromagnetic radiation (90), a first electronic element (200) and a second electronic element (300). The first electronic element (200) is adapted for controlling the emission intensity of the electromagnetic radiation (90), generated by the optoelectronic component (100), within a first intensity range, and the second electronic element (300) is adapted for controlling the emission intensity of the electromagnetic radiation (90), generated by the optoelectronic component (100), within a second intensity range.
