Abstract: A daylight illumination system for integration into a building or larger vehicle comprises a translucent facade element (800) containing a glass sheet and a light redirection element (302 or 708), and a light transport channel (801) for guiding light about horizontally into an interior of the building, the light transport channel comprising one opening attached to the interior side of said facade element and at least one opening towards the interior of the building, characterised in that the light redirection element (302 or 708) is formed as a structured polymer film or sheet attached to a glass sheet of the facade element (800) and is configured for changing the direction of incident light into the about horizontal light transport channel.
