Beschreibung
Zusammenfassung:	An optical deflection tape (10) attachable on a lightguide (20) is provided, comprising a substrate (10A) and at least one pattern (11) formed with a number of periodic pattern features (12) embedded in the substrate (10A) and configured as optically functional cavities (12) filled with a material having a refractive index different from the refractive index of the material of the substrate (10A) surrounding the cavity (12). The pattern (11) is configured to adjust direction of light received thereto such, that light incident at the pattern (11) is deflected to acquire a propagation path through a lightguide medium (20) via a series of total internal reflections and, by virtue of said at least one pattern (11), the optical deflection tape (10) is configured to control distribution of light propagating through the lightguide (20). A method for manufacturing the tape (10) and related uses are further provided.
