Abstract: Lighting fixtures providing light-weight construction and displaying reduced visibility of underlying support elements. The lighting fixtures include a non-opaque, polymer-based frame that provides structure without producing a substantial shadow on the outer display surface thereof when illuminated from the inside. The frame is attached to and extends from a rigid support element, and a lighting element disposed between the support element and the display surface reduces a shadow of the support element from being cast on the display surface. The frame can wrap around and conceal the support element from a first vantage point. The lighting fixture can also be decorated with one or more design elements connected to the display surface of the frame. The lighting fixture can be produced by thermoforming a polymeric substrate into a three-dimensional structural frame and connecting the frame at one end to the support element.
