| 摘要 |
The present invention relates to a light redirection device (1) for redirecting and concentrating direct sunlight (31) into buildings, said device comprising at least one transparent element (10) having a substantially planar top surface (10) in an x-y-plane and a substantially planar bottom surface (14), wherein said top (11) and bottom (14) surfaces are arranged in an angle α to each other around the x-axis, and a light reflector (20) for each transparent element (10) having a planar surface, wherein said planar surface of said light reflector (20) is arranged substantially parallel and adjacent said bottom surface (14) of said transparent element (10), wherein said reflective surface is spaced apart (12) from said transparent element by a transparent medium having lower refractive index than the transparent element (10), so that incident light (31) to the device is refracted by each material transition interface and reflected by the reflecting element (20). The invention further relates to a method for redirecting and concentrating direct sunlight (31) into buildings, using a device (1) according to any of the preceding claims, the method comprising the step of: arranging said device (1) substantially perpendicular to the direct sunlight (31) at noon, having one of its edges adjacent a building wall or window (40). |

1. Light redirection device for redirecting and concentrating direct sunlight into buildings, the device comprising:
a transparent element having a substantially planar top surface in an x-y-plane and a substantially planar bottom surface, wherein the top and bottom surfaces are arranged in an angle to each other around the x-axis, and a light reflector having a reflective surface that is arranged substantially parallel and adjacent to the bottom surface of the transparent element, wherein the reflective surface is spaced apart from the transparent element by a transparent medium having a lower refractive index than the transparent element, so that direct sunlight incident on the light redirection device is refracted by each material transition interface and reflected by the light reflector. |
