Abstract: A light system that includes one or more lighting sheets including a first lighting sheet, wherein the first lighting sheet includes a first plurality of LEDs arranged on a grid of intersecting rows and columns of electrical conductors on an insulating substrate, wherein the first plurality of LEDs emit light having a first color spectrum, wherein the first lighting sheet includes a plurality of holes through the insulating substrate of the first lighting sheet, wherein each one of the plurality of holes through the insulating substrate of the first lighting sheet is positioned between an adjacent pair of rows of electrical conductors and between an adjacent pair of columns of electrical conductors of the first lighting sheet; and an acoustic tile, wherein the first lighting sheet is mounted to the acoustic tile. Some embodiments include a plurality of layered light sheets, optionally individually controlled for color and/or brightness.

Abstract: A door frame protector includes a tube having a slot which extends the entire length of the tube. The tube is preferably a wound paper tube 12-96 inches long. The tube is sufficiently resilient so that it can be opened and placed around a door jamb and then released so that the edges of the slot compressively engage the wall adjacent the door jamb. The protector can protect a new or freshly painted door jamb from damage from being hit or bumped when a building is under construction.

Abstract: An acoustical panel assembly for a suspended ceiling comprising a rigid frame, sound absorbing material, sound transmission attenuation material and a face fabric. The frame is an assembly of extruded members secured together in a polygonal pattern such as a square or a rectangle. The fabric is secured to the frame by gripping elements integral with the frame. Marginal portions of the fabric are captured and hidden in receiving chambers formed by the frame members.
