SPOT LIGHTING SYSTEM WITH ADJUSTED SYMMETRY Russian patent published in 2014 - IPC F21V7/00 F21K99/00 F21Y101/02 

FIELD: electricity.

SUBSTANCE: invention relates to lighting engineering. Spot lighting system (1, 30, 40, 60, 70, 90) contains a tubular reflecting element (3,31,61,91) with reflecting inner surface having input (9) and output (10) apertures, at that output aperture is more than input aperture, and a group of light sources (2, 33, 41, 63, 71, 93) comprising a plenty of light sources placed in configuration of the physical light sources in order to emit light to tubular reflecting element at its input aperture. The tubular reflecting element (3, 31, 61, 91) comprises an odd number of reflecting surfaces (14a-g) more than 3, and each surface is made to generate the primary inverted image of the group of light sources, at that the primary inverted image has configuration of primary inverted image of light sources, and at that the group of light sources (2, 33, 41, 63, 71, 93) is made so that for each of primary inverted image at least half of all secondary inverted images of the light sources being result of the primary inverted image reflection by the reflecting surfaces (14a-g) demonstrates configurations of the secondary inverted images of the light sources, which are different from configuration of physical light sources.

EFFECT: improving homogeneity of emitted light.
