Abstract: The present invention relates in general terms to a lighting device to simulate natural lighting, thus capable of generating at least two light components with different angular distributions having different correlated colour temperature or CCT. The lighting device to simulate natural lighting thus conceived is able to generate a light with two chromatic components having different angular distributions, however effectively preventing the light at a higher colour temperature (bluish light) from generating glare effects or from giving the environment an unnatural colouring that the natural light of the sky and the sun would not produce.

Abstract: The invention relates to a luminaire element (10, 11) for an inspection tunnel (100), in particular for checking shiny surfaces, in particular painted surfaces, comprising at least two, preferably strip-like, arrangements (12) of light sources (13) in a luminaire housing (14) having at least two edge regions (15) lying opposite one another along a longitudinal extension (L) of the luminaire housing (14), wherein the strip-like arrangements (12) of the light sources (13) are formed along the longitudinal extension (L) at the edge regions (16), wherein a light exit surface (20) of the luminaire housing (14) has a higher radiation intensity along the edge regions (16) than in a central region (30). The invention further relates to a luminaire strip (50) having an arrangement of luminaire elements (10, 11) of this kind and to an inspection tunnel having an arrangement of a plurality of luminaire strips (50).

Abstract: A domestic refrigeration device includes a thermally insulated body with an internal compartment delimiting an interior coolable food storage space, a refrigeration apparatus cooling the interior space, a door leaf closing the interior space in a closed state and making the interior space accessible in an open state, and an interior lighting configuration illuminating the interior space with the door leaf open. The interior space has side walls with a depth, edges facing the door leaf, a ceiling and a rear wall rearwardly closing the interior space. The lighting configuration includes a first partial interior lighting configuration illuminating the interior space only at least approximately starting from a distance or space measured from the edges of the side walls facing the door leaf to the rear wall, and a second independent partial interior lighting configuration illuminating only a front region of the interior space facing the door leaf.

Abstract: A refrigeration appliance includes a door having a door rack or racks on the inside of a door leaf and a surface luminaire or lighting fixture disposed substantially perpendicular to the door leaf. The surface luminaire extends in the vertical direction beyond the door rack or racks and serves to illuminate an interior storage space. The surface luminaire is preferably an OLED.

Abstract: A domestic refrigeration appliance includes a thermally insulated body having an internal container which delimits a coolable interior provided for the storage of food, a refrigeration apparatus for cooling the coolable interior space and a door leaf which is provided to close the coolable interior in a closed state and to make the coolable interior accessible in an open state. An interior lighting system includes at least one lighting device for at least partially lighting the coolable interior when the door leaf is open. A light color of light generated by the interior lighting system can be set or adjusted.

Abstract: An illumination apparatus includes at least one illumination device and an elongated optical waveguide. The optical waveguide has a length, two ends, a back side and a front side opposite the back side. One of the two ends is optically coupled to the at least one illumination device, or each of the two ends is optically coupled to at least one illumination device. The back side of the optical waveguide has a coupling-out structure, which is an integral component of the back side of the optical waveguide and is configured to couple the light coupled into the optical waveguide out of the optical waveguide at least over a majority of the entire length of the optical waveguide through the front side of the optical waveguide. A domestic refrigeration appliance having such an illumination apparatus as an interior illumination apparatus is also provided.
