Abstract
An optoelectronic component with a desired color impression in the switched-off state includes, in particular, a semiconductor layer sequence with an active region, that during operation radiates electromagnetic radiation with a first spectrum, and a wavelength conversion layer that is disposed downstream from the semiconductor layer sequence in the beam path of the electromagnetic radiation with the first spectrum, and that at least partially converts a subspectrum of the electromagnetic radiation with the first spectrum into electromagnetic radiation with a second spectrum, and a filter layer that reflects at least a part of the radiation incident from outside onto the optoelectronic component.
