Abstract
The arrangement comprises several trough-shaped parabolic concentrators (3,4,8), filled with a light-refracting medium. The longitudinal axis of the trough is aligned parallel to the direction of the light to be guided. The trough has an acceptance angle of at least 45 deg. , and has maximum light concentration consistent with total reflection. A metallic reflector (6) is positioned at the smaller end of the concentrator (3), separated from it by a very narrow air gap (5). Additional concentrators (4,8) separated by air gaps, consist of a material of a higher refractive index than the first concentrator, and-or have an acceptance angle of almost 90 deg. . USE - Systems with very high degree of reflection. To reflect daylight into the interior of buildings. ADVANTAGE - Reduces reflection losses.
