Abstract: An LED specification system is provided having at least one LED light output device. The LED light output device has an LED light source, a first exchangeable face panel selectable from a plurality of potential exchangeable face panels, and a housing for locating the exchangeable face panel relative to the LED light source and for orienting the LED light source such that light from the LED light source passes through the first exchangeable face panel. The LED specification system further includes a user interface for selecting at least one preferred output characteristic for light from the LED light output device. The preferred output characteristic is defined by a metric value. The LED specification system further includes a transformation module for defining an LED specification value based at least partially on the defined metric value and a characteristic of the LED light source.

Abstract: A light emitting diode (LED) lighting device is provided having a panel forming a shape, the panel having at least one opening. The device further has a frame bounding the panel having a cross-sectional profile in the shape of the panel. A lens corresponds to each of the at least one opening, the lens extending partially through the opening from a back side of the panel to the front side of the panel. The device further includes at least one LED element located behind the lens and a diffuser either between the at least one LED element and the lens or incorporated into the lens.

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: One embodiment of a light emitting diode (LED) lighting device comprises multiple LED light sources disposed on multiple elongated circuit boards, with each LED light source being electrically connected to one of the circuit boards. The elongated circuit boards are electrically coupled using electrical passageways to provide power to the circuit boards at intervals along the length of the elongated circuit boards, and the light sources disposed on the circuit boards emit light in the same direction perpendicular to the elongated circuit boards. The electrical passageways can be wires or groups of wires.
