In one embodiment, the optoelectronic semiconductor device comprises a carrier having electrical connection surfaces on a carrier upper side. At least four semiconductor chips are configured to emit light of different colors from each other. The semiconductor chips are mounted close to each other on the connection surfaces so that a distance between adjacent semiconductor chips is at most 100 &#x3bc;m in a top view on the carrier upper side.

Optoelectronic semiconductor device and flashlight

A lighting device for lighting an interior of a domestic electrical appliance is configured to be operated in different lighting modes which differ from one another by the spectral composition of the light of the lighting device delivered into the appliance interior. In some embodiments, the lighting device comprises two light-emitting diodes which differ from one another in terms of the spectral content of the light delivered thereby. The different lighting modes of the lighting device differ from one another by a different operating combination of the light-emitting diodes. By varying the duty cycle and the pulse frequency of a pulse-width-modulated control signal, a control assembly is able to transmit two different pieces of control information to the lighting module in order to control the two light-emitting diodes individually.
