Abstract: The present invention relates to a surface-mounted light and/or camera (1) for arrangement on a wall (5), in particular an inside wall of a machine, having a housing (10) with a front side area (12), a rear side area (14) and side walls (13), at least one illuminant (50) and/or at least one camera (60), with at least one recess (20) being provided in the rear side area (14), in which at least one fastening means (30) is arranged, wherein the fastening means (30) in the recess (20) forms a trap which is beveled towards the rear side area (14). The present invention also relates to a connecting pin (2) for fastening the surface-mounted light and/or camera (1) to a wall (5) and a surface-mounted light and/or surface-mounted camera fastening system (3).

Abstract: The present invention relates to a built-in light and/or camera (1) for arrangement in an installation opening (4) of a wall (5), in particular an inner wall of a machine, having a housing (10) with a front side area (12), a rear side area (14) and side walls (15, 16, 17, 18), wherein at least one camera (30) and/or at least one light source (40) is arranged in the front side area (12), wherein a stop (20) is arranged in the front side area (12), wherein at least one fastening (50) is provided that protrudes over one of the side walls (15, 16, 17, 18), and wherein the at least one fastening (50) is configured to form a spring-loaded form fit of the wall (5) between the stop (20) and the at least one fastening (50) like a trap when inserted into the installation opening (4).

Abstract: A luminaire (1) having a preferably flat light exit region (2) that is surrounded by a rectangular light frame (10), wherein the luminaire frame (10) spans a first plane (E) and has a frame height (H) that is perpendicular to the first plane (E) and, at one of its corners (11), a beveled surface (12) in which a plug contact (30) is arranged, and an electromechanical plug connector for a luminaire of this kind are provided.

Abstract: A device for disinfecting liquids, comprising at least one photosensitizer and at least one bypass which comprises radiation sources and which is arranged such that light emitted from the radiation sources passes through the liquid. The bypass has at least one layer in which the radiation sources are arranged, and the radiation sources emit visible light and a method for disinfecting liquids using a device, wherein the light emitted from the radiation sources excites the at least one photosensitizer from a base state into an excited state, and reactive oxygen species are formed by means of the energy dispensed by the photosensitizer when transitioning from the excited state into an energetically lower state.

Abstract: Light with housing, a plurality of illuminants arranged in the housing, a covering disc that closes the housing in the direction of radiation and a film for altering the radiation characteristics of the illuminants, which is arranged in front of the illuminants in the direction of radiation, wherein the film is arranged between the covering disc and a supporting disc, wherein the film is in direct contact with the two discs.
