OPTICAL TRANSMISSION ELEMENT FOR CAPTURING AND REDIRECTING INCIDENT RADIATION

摘要

An optical element comprising a plurality of transparent layers comprising one or more passive layers (11) and one or more active layers (12) wherein said passive layers (11) facilitate the transmission of electromagnetic radiation in a substantially unaltered form and the at least one active layers (12) include an active material dispersed through the active layer and having the capacity to intercept electromagnetic radiation of at least one first predetermined wavelength or range of wavelengths and redirect at elast a portion of energy of the intercepted radiation into the interior of the optical element, said layers being in face-to-face relationship and being optically coupled to each other.
