The system may have a window. The window may have a structured window layer, such as a structured window layer formed from a laminated glass layer. The window may separate an exterior region from an interior region within the vehicle. A light guide illuminator in the window may provide illumination to the interior region. The light guide illuminator may have a light guide that receives light from a light source. The light guide may have a light scattering structure density that increases as distance from the light source increases, such that the internal illumination is uniform across the light guide illuminator. An adjustable optical component layer, such as a light modulator and/or haze compensation layer, may be interposed between the light guide and the structured window layer, the adjustable optical component layer having a light scattering structure density that decreases with distance from the light source.
系统可具有窗。该窗可具有结构化窗层,诸如由层合玻璃层形成的结构化窗层。该窗可将外部区域与车辆内的内部区域隔开。该窗中的光导照明器可为该内部区域提供照明。该光导照明器可具有从光源接收光的光导。该光导可具有随着距该光源的距离增大而增大的光散射结构密度,使得该内部照明在该光导照明器上是均匀的。可在该光导与该结构化窗层之间插置诸如光调制器和/或雾度补偿层的可调光学部件层,该可调光学部件层具有随着距该光源的距离而减小的光散射结构密度。
