Claims40
A lighting fixture, comprising:
- one or more side panels comprising one or more thermoplastic sheets welded together without hardware at corresponding flanges bent inward from an outer surface of the one or more panels, such that the welded one or more thermoplastic sheets form an outer shade element;
- one or more side panels comprising one or more thermoplastic sheets welded together without hardware at corresponding flanges bent inward from an outer surface of the one or more panels, such that the welded one or more thermoplastic sheets form an inner shade element;
- the inner shade element forming a cavity with a passageway therethrough;
- a bottom panel coupled to the outer shade element and the inner shade element without hardware;
- and
- a top panel coupled to the outer shade element and the inner shade element without hardware;
- wherein:
- the one or more side panels include a diffusion layer;
- and
- the lighting fixture includes one or more light sources.
7 more elements
A lighting fixture, comprising:
- a plurality of side panels coupled together without hardware to form an outer shade element, wherein each side panel of the plurality comprises a resin sheet;
- a plurality of side panels coupled together without hardware to form an inner shade element, wherein each side panel of the plurality comprises a resin sheet;
- the inner shade element forming a cavity with a passageway therethrough;
- a resin bottom panel coupled to the outer shade element and the inner shade element without hardware;
- and
- a resin top panel coupled to the outer shade element and the inner shade element without hardware;
- wherein:
- the plurality of side panels forming the outer shade element are solvent-welded together at one or more flanges;
- the plurality of side panels forming the inner shade element are solvent-welded together at one or more flanges;
- and
- the top panel and bottom panels are solvent welded to the inner shade element and outer shade element using a solvent that at least partially dissolves the contacted resin upon contact before solidifying the contacted resin.
8 more elements
