A light collection system for use in buildings consisting of a concave mirror with a convex mirror aligned on the focal axis of the concave mirror (10) inside the focal point of the concave mirror (10). The convex mirror (12) radiates light directed onto it from the concave mirror (10) as a substantially parallel beam of light which passes through a central aperture (20) of the concave mirror (10) and through a cylindrical flange (21) located behind the concave mirror (10). Temperature sensors (32) monitor the position of the substantially parallel beam so that the concave mirror/convex mirror assembly can be controlled to ensure that the parallel beam of light is centred along the focal axis of the concave mirror and along the central axis of a light distribution system connected to the cylindrical flange (21). |
