Abstract: An apparatus for the measurement or visual matching of colors and color effects on a flat or slightly curved sample is proposed, with a lighting apparatus, a sample support and an observer location, wherein the direction of observation of a sample is adjustable by translational displacement of the sample and in the process the lighting direction of the light which illuminates the sample surface remains constant to the sample surface.

Abstract: An advisory lighting with a luminous body has at least one light-radiating light outlet surface. The light outlet surface is divided up into part surfaces radiating in various colours. A light source arrangement radiates light into the luminous body, wherein the luminous body has a light conducting plate arrangement or a hollow body arrangement with limiting walls. The luminous body is composed of light conducting plates or hollow bodies arranged above, next to and/or in each other and having various part surfaces. Various light sources are assigned to the light conducting plates or hollow bodies, corresponding to the part surfaces radiating in various colors, which light sources radiate variously coloured light into the respective light conducting plates or hollow bodies.

Abstract: This invention concerns a device for visually inspecting the surface condition of large-dimension surfaces to be matched, in particular painted bodywork, with substantially vertical and horizontal surfaces to be matched or painted surfaces. Provided at a lateral spacing from the object are vertically disposed luminous elements whose principal radiation direction, viewed in horizontal planes, is directed at an oblique angle to the substantially vertical surfaces to be matched. The luminous elements are protected against being looked at directly from an observation position (B), located in the space between the object (1) and the luminous elements at least from direction R2 of the normals of the vertical surface to be matched.

Abstract: An apparatus is proposed for the color matching or colorimetry of colored samples, which are arranged in a sample support. It comprises a lighting device which illuminates the sample in a main beam direction and an observer provided at an observation position or a measuring device arranged at an observation position, the sample and observation position having a fixed coordination with each other. The sample and the lighting device are arranged in fixed coordination with each other and, to set different angles of observation between the direction of observation from the observation position to the sample and the main beam direction, the sample and the lighting device are pivotable about a common axis of rotation.
