Abstract: A cooktop is designed to be operated either in a cooking operation or in a lighting operation, with the modes of operation not being able to occur together. Within cooking operation, the cooktop controller controls heating devices of the cooktop and light sources of the cooktop in a cooking lighting mode, wherein a luminosity of the light sources is limited to a cooking luminosity below the maximum luminosity in the process. Within lighting operation, the light sources are not controllable by the cooktop controller but can only be controlled by the light controller in an illumination lighting mode, wherein to this end the light controller receives the corresponding commands for the light sources from an external control apparatus by way of a communications device. In this case, a luminosity of the light sources can be maximal.
