Abstract: A disclosed lighting apparatus includes a light-diffusive plate having opposing first and second faces bounded by one or more sides. A first electrically conductive sheet is disposed on the first face of the light-diffusive plate, and an electrically insulative sheet is disposed on the first electrically conductive sheet. A second electrically conductive sheet is disposed on the electrically insulative sheet. A plurality of light-emitting diodes (LEDs) have light emitting portions that face a portion of the light-diffusive plate. The LEDs are electrically coupled to the first electrically conductive sheet and to the second electrically conductive sheet.

Abstract: A lighting apparatus includes a light-diffusive plate having opposing faces bounded by one or more sides. The plate has disruptions on a first face of the opposing faces and a first channel along at least a portion of a first side of the one or more sides. A first cover has first and second surfaces disposed over the first channel with the first surface facing the first side of the light-diffusive plate. A plurality of light-emitting diodes (LEDs) is disposed on the first surface of the first cover and within the first channel. The LEDs electrically coupled with wiring are integrated with the first cover.
