Apparatus for collection and trasmission of light

Abstract

An apparatus is presented for capture and transfer of sunlight. The apparatus comprises a light capturing section, an optical fibre which comprises a first end, a second end and a light transferring section arranged between the ends, which light transferring section along its entire length has an essentially constant crosssectional area and which first end is connected to the light capturing section, and a body with essentially the same refractive index as the light transferring section. The second end of the optical fibre is connected to a first end of the body, the second end of the body, which is opposite the first end of the body, has a larger crosssectional area than the light transferring section and first and second ends of the body are essentially plane parallel.

Dependencies are inferred from the claim text.
