<p>A tubular skylight for lighting rooms with natural light, comprising a tubular body (2) with a reflective inner surface which leads into a room and has, at its external end, a natural light collector assembly (3) and, at its internal end, a light diffuser (30). The collector assembly (3) comprises, inside an optically transparent dome (4) arranged so as to close the tubular body (2), a mirror-finished body (10) which is substantially shaped like a cylindrical band with mirror-finished inner and outer surfaces (10a, 10b). The axial width of the band-like body varies gradually from a minimum-width point to a maximum-width point, which lie diametrically to each other. It is also possible to provide a cylindrical refracting body (20) that surrounds said mirror (10). <IMAGE></p> |
