Abstract: The invention relates to an arrangement (100) comprising a lighting system (110) and a target object (120), wherein the lighting system (110) is arranged to illuminate a target surface of the target object (120) with a primary light output (111) and with a secondary light output (112). Each of these light outputs has an illumination spectrum representing a color. The two illumination spectra are different, but the two colors are substantially the same. The target surface has a first target surface area and a second target surface area. When the first and second target surface areas are illuminated with the primary light output (111), they have a contrast that is lower than when they are illuminated with the secondary light output (112). The arrangement of the invention can be used for atmosphere creation or for attracting attention to the target object (120).

Abstract: A lighting system (10) is provided that enhances the perceived surface lighting effects on specular and refractive objects (14). Light sources (12) are arranged in spatial distribution to one another above, below, or in at least partially surrounding relation to the specular and/or refractive object to be illuminated. A controller (16) is configured, programmed and/or structured to drive each light source with a temporal variation in a lighting parameter (18), such as the intensity, color, or spectral content of each light source, while maintaining a uniform level of illuminance at the object's surface. The geometric arrangement of the light sources coupled with the controller produces a visually perceptible sparkle at the surface of the object.
