A door in a locker with a textured substrate panel that has a top edge, side edge, and a texture or a patterned portion between the top edge and the side edge that creates a uniform distribution of light from a light source positioned relative to illuminated indicia. The top edge and the side edge are generally straight connected by a corner. Illuminated indicia is positioned on a surface of a substrate panel relative to the top edge, the side edge, the corner, or a combination of them. The position of the illuminated indicia includes locating it on an exterior plane, a posterior plane, or an interior plane relative to a surface of the substrate panel.

This disclosure describes devices that can integrate a solar energy collection device, such as a solar collection film or panel, and an illuminated display. Embodiments of the present solution include a display that includes a solar film layer topped by a transparent or semi-transparent display layer enabled by an edge-illuminated light guide. The semi-transparent display can allow sufficient light transmission to cause the solar layer to charge an integrated battery, which, in turn, can illuminates the display. This solution can enable wireless displays that can be seen day or night.

An interior aircraft light unit includes at least one light source, in operation emitting light with a source side light intensity distribution, the source side light intensity distribution having a first intensity region and a second intensity region, with the first intensity region having a higher light intensity than the second intensity region, and a semi-transparent layer, disposed between the at least one light source and an outside of the interior aircraft light unit, for transforming the source side light intensity distribution into an adjusted light intensity distribution, wherein the semi-transparent layer has a transparency distribution having a lower degree of transparency in the first intensity region than in the second intensity region, such that the adjusted light intensity distribution is closer to an even light intensity distribution than the source side light intensity distribution.
