Abstract

Non-imaging radiation collecting and concentrating devices, and assemblies, are disclosed. The non-imaging radiation collecting and concentrating devices comprise an entrance aperture for receiving incoming radiation, an exit aperture located opposite to the entrance aperture for outputting concentrated radiation, and one or more concaved reflectors arranged between the entrance and exit apertures. The concaved reflectors define an acceptance angle of the device relative to an optical axis thereof and configured such that their optical focuses are located between edges of the exit aperture and the optical axis, thereby substantially preventing escape of the incoming radiation received in the entrance aperture within the acceptance angle and providing substantial uniform radiation collection at the exit aperture of the device.

Abstract

An electromagnetic radiation collecting device is presented, which is particularly useful for the collection of solar radiation, providing optimal radiation collection throughout the daytime, and throughout yearly seasonal changes. The collector entails a redundant number of static collectors arranged in such a manner as to provide maximal and chronologically evened collection outline.

Abstract

An electromagnetic radiation collecting device (10) is presented, which is particularly useful for collection Sun radiation and provides for optimal radiation collection throughout the day hours. The device comprises a base side (14) having a curved surface of A-shaped configuration defined by two tilted arms (11, 12) located in two intersecting planes and presenting radiation collecting surfaces of the device for collection of radiation and directing collected radiation to one or more radiation receiving elements (not shown here) located within a receiving plane (18); and two opposite sides extending from the base side (14), the opposite sides comprising reflectors (11a, 12a; 11b, 12b) on their inner surfaces facing one another, for collecting incoming radiation and reflecting collected radiation towards the one or more radiation receiving elements.

Abstract

The present invention provides a passive solar lighting system, which is designed to produce a balanced flux throughout the day, by effecting increased sunlight collection in the earlier and later hours of the day when solar radiation is scarce, while compromising performance during midday when solar radiation is abundant.
