Abstract: The present invention is a night light that plugs into an electrical outlet and has means that allow the night light body, without unplugging the night light, alternatively to conceal from view the entire electrical receptacle in a first orientation and to expose one of the electrical receptacle's outlets for use in a second orientation. The invention thus serves to conceal electrical receptacles in an aesthetically pleasing way while operating as a night light. It can be reoriented from that position, without removing it from the electrical outlet into which it is plugged, to expose for use by another electrical device the electrical outlet of the electrical receptacle not being used by the night light, while continuing to function as a night light.

Abstract: LED lighting sheets feature foldable light-sheets including multiple illumination modules electrically interconnected such that unremoved illumination units remain energized upon removal of one or more by horizontal, vertical and or diagonal cuts. A new and non-obvious conductor geometry forms a 3D mesh that is resistant to cutting from any direction in 45 degree increments. Relatively constant illumination levels are maintained in the remaining LEE's by using relatively high resistance series connected current limiting resistors for each LEE. Each current limiting resistor may be, for example, ten times the resistance of the entire lower ribbon conductive layer. Tunable color LEE's are included.
