ABSTRACT:
A light-emitting electronic component is described that includes at least one light-emitting element intended for the emission of light with a predetermined spectral distribution, at least one filter element arranged in a beam path of the light with the predetermined spectral distribution, the transmission property of the filter element with respect to the light with the predetermined spectral distribution determining the spectral distribution of the light emitted by the light-emitting component, with the transmission property of the filter element being tunable during operation of the light-emitting electronic component. The color of the light emitted by the component can be tuned by tuning the transmission property of the filter element.
