摘要:
The invention relates to a luminous window which can function both as a broad area light source and as a transparent window. The broad area light source is achieved by coupling light into a plate-shaped light guide, e.g. via the edges of the light guide, and extracting light from the light guide using geometric protrusions or diffraction gratings into a scattering layer which outputs the broad area light. The transparent window is achieved by switching the scattering layer into a non-scattering state, and possibly switching off the light source, so that light can propagate freely through the light guide and the scattering layer.
摘要(中):
本发明涉及一种能够起到广域光源和透明窗口的作用的发光窗。 广域光源通过将光耦合到板状光导中来实现。 通过导光体的边缘,并且使用几何突起或衍射光栅将来自导光体的光提取到输出广域光的散射层中。 通过将散射层切换成非散射状态并且可能关闭光源来实现透明窗,使得光可以通过光导和散射层自由传播。
