Abstract: A light emitting diode (LED) lighting device having a front housing with an outer profile and a shape formed from a translucent or transparent material. The front housing has an edge protrusion extending from a front housing body along the outer profile. The edge protrusion bounds an inner light chamber. A rear housing is separately provided having a size and outer profile substantially corresponding to the shape of the front housing. The rear housing is opaque or impervious to light, and has a substantially planar rear panel and a rear panel protrusion extending from the rear panel adjacent to and spaced apart from an outer edge of the rear housing. The rear panel protrusion and the rear panel further bound the inner light chamber. At least a portion of the edge protrusion surrounds the rear panel protrusion.

Abstract: A method is provided for assembling an LED lighting device. The method includes providing a polyurethane compound and mixing a diffuser compound with the polyurethane compound to form a combined compound. The method then includes injecting the combined compound into a cartridge, applying a vacuum to the cartridge, and sealing the cartridge at a first pressure lower than ambient pressure. The method then includes providing an LED lighting assembly having a front panel and a frame, the frame extending past the front panel to form an enclosed tray in a shape of the front panel. The combined compound is then dispensed from the cartridge into the enclosed tray.

Abstract: A light emitting diode (LED) lighting device includes a frame having a substantially consistent cross-sectional profile and an inner surface; a front panel having a front surface sized and shaped to substantially correspond to the inner surface of the frame, a rear surface having a shape substantially corresponding to the shape of the front surface and a size smaller than the front surface, an edge profile extending from the front surface to the rear surface; and an adhesive positioned between the edge profile adjacent the rear surface of the front panel and the inner surface of the frame; a rear panel sized and shaped to correspond to the frame and spaced apart from the front panel a distance about the thickness of the frame; and at least one LED mounted on the rear panel.

Abstract: A system is presented for predicting the amount of energy required by a manufacturing plant over a period of time, and then providing a recommendation on the best amount of energy to sell at each period, taking into consideration the energy requirements based on the production schedule, the price of energy, possible penalties for over selling energy, and other factors. A user interface is provided to present relevant information to a user, allow the user to plan the use of energy, and determine the energy offering for sale in each period. Based on a known future production schedule of a steel mill, implementations provide a forecast of electrical energy usage per hour over the same time horizon as the production schedule. Based on the forecast and electricity selling and billing rules, a recommended amount of energy to be sold to the market by the hour is presented with the corresponding offer price.

Abstract: A light emitting diode (LED) lighting device is provided comprising a frame forming a shape and having a substantially consistent cross-sectional profile, with the frame having an inner surface. A front panel is provided for the LED lighting device having a front surface sized and shaped to substantially correspond to the inner surface of the frame, and a rear surface having a shape substantially corresponding to the shape of the front surface and a size smaller than the front surface. The front panel is provided with an edge profile having a depth extending from the front surface to the rear surface and an adhesive having a thickness is positioned between the edge profile adjacent the rear surface of the front panel and the inner surface of the frame.
