차량 지붕을 위한 투명 지붕 조립체는 투명 영역을 가지는 패널, 패널에 광을 제공하도록 배열된 광원, 및 패널의 투명 영역의 표면 상에 배열된 아웃 커플링 패턴을 포함한다. 아웃 커플링 패턴은, 패널 내로 도입되고 패널에서 전파되는 광의 아웃 커플링을 위한 광 재지향 재료의 도트들을 포함하며, 여기서 도트들은 각각 150 미크론 이하, 바람직하게 80 미크론 이하의 대표 지름을 가지며, 아웃 커플링 패턴의 도트들의 전체 도트 표면적은 투명 영역의 전체 표면적의 10%보다 작다. 그러므로, 투명 영역은 주간 동안 차량의 내부로부터 차량의 외부로 투명하게 보이고, 광원이 켜지면 충분한 광이 내부로 제공된다.

    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.
