Abstract
An illumination system () for spot illumination comprising: a tubular reflector () with a reflective inner surface, the tubular reflector having an entrance aperture (), and an exit aperture () being larger than the entrance aperture; and a light-source array () comprising a plurality of light-sources arranged in a physical light-source configuration to emit light into the tubular reflector at the entrance aperture thereof. The tubular reflector () comprises a plurality of reflective surfaces (-) each being arranged to provide a primary mirror image of the light-source array, the primary mirror image having a primary mirror image light-source configuration; and the light-source array () is configured in such a way that, for each of the primary mirror image, at least half of all secondary mirror images of the light-source array resulting from reflection of the primary mirror image by the reflective surfaces (-) exhibit secondary mirror image light-source configurations that are different from the physical light-source configuration.
