An optoelectronic module for a light barrier for fill height monitoring of an ice collection container in a household ice maker includes a module housing, which bears a light passage surface located at the boundary between the optoelectronic module and the space outside the module for the passage of a beam of light of the light barrier. The module further has a printed circuit board accommodated in the module housing, an optoelectronic component mounted on the printed circuit board, serving as a light transmitter or receiver, with a main lobe axis, and a cylindrical light-guiding element for guidance of the light beam located in the beam path between the light passage surface and the optoelectronic component, and at a distance from the component.

A domestic laundry-washing appliance including an optical measuring device for obtaining measured values which are representative of a spectral transmission signature of a washing liquid used during operation of the laundry-washing appliance for cleaning textiles, and a control device which is adapted to categorise a cleaning agent contained in the washing liquid in respect of its chemical properties on the basis of the spectral transmission signature obtained, and to control the operation of the laundry-washing appliance in dependence on the categorisation result. The categorisation result can indicate, for example, a distinction between a heavy-duty detergent containing bleach and another bleach-free detergent.

A pyrolytic oven comprises a housing and a muffle delimiting a cooking chamber inside the housing. A lighting module serves to illuminate the cooking chamber, wherein the lighting module has a cooling structure with an arrangement of cooling extensions formed in particular as pins or ribs, which project into a gap between housing and muffle and have a convection effect in a cooking mode of the oven. A fan device of the oven is configured and controlled to generate an air flow encountering the cooling structure in the gap in a pyrolytic mode of the oven. The cooling structure of the lighting module further has a wall formation, which in pyrolytic mode generates a wind shadow relative to the air flow for a number of cooling extensions of the cooling structure arranged distributed in a transverse plane to the flow direction of the air flow.

A light bar includes an arrangement of several light elements reciprocally spaced behind one another in the longitudinal bar direction where each light element produces a light beam, a reflection surface formed on a light-impermeable reflector body and producing a diffuse scattering effect where a first portion of the light beam of each light element is directed at the reflection surface, a light-permeable window element at which light produced by the light elements exits the light bar. A second portion of the light beam that is different from the first portion is directed past the reflection surface onto the light exit window. The light radiated by the light bar is composed of a direct light proportion and a scattered light proportion, the relative ratio of which in a suitable configuration of the reflector body and the window element can be different in different radiation directions of the light bar.

A domestic refrigerator has a cold chamber delimited by walls, and a lighting module inserted into a wall opening of a delimiting wall of the cold chamber. The lighting module has a planar, transparent light outlet pane arranged parallel to the delimiting wall, a frame inserted into the wall opening, at least one light-emitting diode which, in a projection perpendicular to the pane plane of the light outlet pane, is arranged so that it is concealed, and a light reflection surface, arranged behind the light outlet pane and irradiated by the light-emitting diode where the light reflection surface, in a region that is visible through the light outlet pane when viewed perpendicularly to the pane plane, has all over a roughness depth Rz of between 2.5 &#x3bc;m and 8.0 &#x3bc;m and an arithmetical mean roughness value Ra of between 0.63 &#x3bc;m and 2.4 &#x3bc;m.

A shelf for a domestic cooling device has a base plate with an edge face, an edge strip extending along the edge face of the base plate where the edge strip has a strip body covering the edge face, and at least one light source element where the strip body forms a light reflection surface which is arranged in a propagation path of the light of the at least one light source element and has a diffuse reflecting effect for at least a portion of the light that is incident thereon.

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.

A domestic refrigeration device comprises an interior for storing foods, a light source arrangement which is configured to emit light, in particular white light, of different spectral characteristics into the interior, and a sensor unit which is configured to optically detect light emitted by the lit interior, to allocate to the detected light a value that is characteristic of the color of the emitted light, and to control the light source arrangement in such a manner that light of a specific spectral characteristic, which is dependent on the value that is characteristic of the color, is emitted.
