Abstract

A transparent roof assembly for a vehicle roof (1) comprises a panel (2) with a transparent area (25), a light source (21, 22) arranged to provide light into the panel (2) and an out-coupling pattern (20) arranged on the surface of the transparent area of the panel (2). The out-coupling pattern (20) comprises dots (23) of a light-redirecting material for out-coupling of light introduced into the panel (2) and propagating in the panel (2), wherein the dots (23) each have a representative diameter of 150 microns or less, preferably 80 microns or less and wherein a total dot surface area of the dots of the out-coupling pattern is smaller than 10% of a total surface area of the transparent area (25). Thus, the transparent area appears transparent during daytime looking from an interior of the vehicle to an exterior of the vehicle, while sufficient light is provided into the interior when the light source is switched on.
