Abstract: A tubular skylight, comprising a tubular body (2) provided with an inner reflecting surface (3), a light collector (4) mounted to a first end of the tubular body (2) and a light diffuser (6) mounted to a second end of said tubular body (2). The skylight further comprises a source of artificial light (9) external to the tubular body (2) to enable it not to interfere with the natural light, and mounted in the vicinity of the diffuser (6). This artificial-light source (9) is preferably defined by a plurality of LEDs positioned around the diffuser (6) itself.

Abstract: A tubular skylight for lighting rooms with natural light, comprising a tubular body with a reflective inner surface which leads into a room and has, at its external end, a natural light collector assembly and, at its internal end, a light diffuser. The collector assembly comprises, inside an optically transparent dome arranged so as to close the tubular body, a mirror-finished body which is substantially shaped like a cylindrical band with mirror-finished inner and outer surfaces. 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 that surrounds said mirror.
