    • The invention relates to an optoelectronic device for emitting mixed light comprising light in a first and a second wavelength range. Said device comprises in particular a first semiconductor light source (1) with a first light-emitting diode (11), which during operation emits light in the first wavelength range with a first intensity, a second semiconductor light source (2) with a second light-emitting diode (21), which during operation emits light in the second wavelength range with a second intensity, the first and the second wavelength ranges being different from one another, and a resistance element (3) comprising a temperature-dependent electric resistor. The first wavelength range and/or the first intensity of the light emitted by the first semiconductor light source (1) has or have a first temperature dependence and the second wavelength range and/or the second intensity of the light emitted by the second semiconductor light source (2) has or have a second temperature dependence that differs from the first temperature dependence, the resistance element (3) and the first semiconductor light source (1) form a series circuit (4) and the series circuit (4) and the second semiconductor light source (2) form a parallel circuit (5).
