Abstract
The window panel includes a plurality of sets of reflecting surfaces which are spaced apart from and facing each other and which transmit the incident light at least in part by multiple reflections. The sets of reflecting surfaces are arranged parallel to each other in a panel. In at least one embodiment the sets of opposed reflecting surfaces converge in the direction of incident light travel through the window panel and infrared reflecting means are provided to reflect infrared light attempting to pass through the window panel in a direction opposite to the direction of travel of the incident light.
