Abstract: A durable LED light engine includes a printed circuit board including LEDs mounted thereon positioned between a substantially U-shaped top enclosure and a bottom enclosure. Once assembled together, the combination of the substantially U-shaped top enclosure, the printed circuit board and the bottom enclosure are held together with a molding material.

Abstract: Enclosures with grommetless strain relief are provided, each including a base and a cover. The base has a bottom and four sidewalls arranged to provide an open box-like structure. A first of the sidewalls of the base is configured with a wire routing slot at its perimeter. The cover has a top and four sidewalls arranged to provide an open box-like structure configured to couple with the base, so as to provide a strain relief for an electrical wire passing through the wire routing slot. The wire is pressed against a length of the first sidewall of the base by a first sidewall of the cover. The enclosure may include other features, such as rounded edges in the wire routing path, a wire guide and/or strap to inhibit wire movement between the first sidewalls, and/or one or more locking mechanisms configured to secure the cover to the base.

Abstract: Systems and methods for mounting light emitting diode (LED) lighting modules in a cabinet or box sign. Mounting systems include components for mounting LED lighting modules to cabinet sign support structures within the interior structure of the cabinet or box sign. LED lighting modules include LED light bars having one or more LED lighting modules mounted thereon. Each mounting system includes a component for attaching or connecting the mounting system to a support structure within the cabinet or box sign, as well as a component for attaching or connecting one or more LED lighting modules mounted onto a light bar to the mounting system.

Abstract: A durable LED light engine includes an printed circuit board including LEDs mounted thereon positioned between a substantially U-shaped top enclosure and a bottom enclosure. Once assembled together using alignment holes and projections, the open spaces in the combination of the substantially U-shaped top enclosure, the printed circuit board and the bottom enclosure are filled with a plastic sealant. Once cooled, the plastic sealant holds the combination of the substantially U-shaped top enclosure, the printed circuit board and bottom enclosure together.

Abstract: A method for producing an output in response to an interaction with a print element on a sheet is disclosed. In one embodiment, the method includes placing a sheet comprising a print element on a surface of a base unit. A user can then mark on the sheet in the vicinity of the print element with a marking instrument. An audio output that corresponds to the print element is generated.

Abstract: A lamp including a two-sided source plate, a plurality of light sources, a lens, a diffuser plate, and a driver insulator is disclosed. One set of the light sources generates white light and is attached to one side of the source plate. Another set of the light sources generates colored light and is attached to the source plate's other side. The lens encapsulates the white light-generating set, and redirects that white light. The driver insulator and the diffuser plate are each in contact with the source plate's other side. The driver insulator, diffuser plate, and that side of the source plate define a light box region that contains the colored light-generating set of light sources. The driver insulator acts as a reflector, and the diffuser plate acts as a diffuser, such that colored light is dispersed from the light box region through the diffuser plate.
