Abstract: Linear lighting using light-emitting diode (LED) light engines is disclosed. The linear lighting includes a printed circuit board (PCB) with a number of LED light engines disposed on it. A light guide is disposed on the PCB adjacent to the LED light engines. The light guide accepts the light from the LED light engines in a first location and is arranged to emit the light at a desired position that is spaced from the first location. By lengthening the optical path, the light guide may spread the emitted light and provide a more uniform appearance for the linear lighting.

Abstract: A strip of linear lighting with distributed power conversion is disclosed. The linear lighting includes a flexible PCB. The flexible PCB is divided into repeating blocks, which are arranged electrically in parallel with one another between power and ground. Each repeating block includes power conversion and conditioning circuits. A plurality of LED light engines are connected to the outputs of the power conversion and conditioning circuits, electrically in series with one another. The power conversion and conditioning circuits typically include at least a full-bridge rectifier. A pair of conductors run the length of the PCB adjacent to it and are connected to each of the repeating blocks. A flexible, transparent covering surrounds the PCB and pair of conductors.

Abstract: Embodiments of the invention relate to connectors for connecting strips of light-emitting diodes (LEDs) end-to-end and for connecting a single strip of LEDs to a power source. The connectors define a compartment to receive a strip of LEDs. Tabs extending inwardly from the sides of the connector retain the strip. Electrical contact with the strip is made by a pair of spring clip contacts that bear against electrical terminals on the strip. A hinged lid has an opening positioned so as not to obstruct the last LED on the strip, and carries a downwardly-facing block that bears against the spring clip ends to keep them in contact with the terminals of the strip. In a strip-to-power connector, the connector defines one compartment for each conductor, and each conductor carries connecting structure. Ends of the spring clip connectors carry complementary connecting structure.

Abstract: Junction boxes for enclosing and making electrical connections to LED drivers are disclosed. The junction boxes include a bottom or base and a cover. Dividers arising from the base divide the junction box into high-voltage and low-voltage compartments. A cut-out open at the top of each divider allows a driver to be placed in a junction box without having to pull wires through holes or openings. Typically, the base is open along the top and along at least a portion of one sidewall, with the cover being L- or U-shaped to complete the enclosure. Various mounting mechanisms are disclosed for securing drivers within junction boxes. Embodiments that can house several drivers or components within one junction box are disclosed, as are weather- and water-resistant embodiments.

Abstract: A power and control assembly is disclosed. An LED driver is sized and adapted to fit within a single compartment of an electrical gang box, such as a two-gang box. An alternating current (AC) dimmer or other component is installed in an adjacent compartment. The AC dimmer supplies its output to the LED driver, which converts the AC power to an appropriate direct current (DC) power for LED lighting fixtures. The LED driver is typically recessed into the compartment, and is covered by a switch or another control element. In some cases, the switch may be a mechanical dummy selected for its aesthetic or fascial characteristics. In other cases, the switch or control element may be functional. With similar multiple-gang boxes, a number of drivers may be installed in the gang box and switches may allow both dimming and zone control.

Abstract: A connector for light-emitting diode (LED) strip light is disclosed. The connector has a cavity with conductive longitudinal and transverse pins that, when the connector is assembled with an LED strip light in a cavity within the housing of the connector, penetrate the insulation of the strip light to make electrical contact with the strip light's conductors. The connector also includes gasket seals and a removable portion that exposes the cavity. The removable portion may include a window to expose any LEDs that may be within the housing of the connector.

Abstract: Connectors for connecting light emitting diode (LED) strip light to power are disclosed. The connectors include a housing with a first opening sized to accept an LED strip light and a second opening for a power cord or electrical leads. The openings open into an interior cavity with an internal vertical barrier to separate power and ground leads. Gripping structures proximate to the first opening retain the strip light. A gasket or gaskets within the connector seal the connector from the elements. The second opening may carry a strain relief molded to the power cord. Additionally, an adapter or nipple may be provided to connect the connector to conduit.

Abstract: A joint support and strain relief that provides support for the entire joint between a power cord and a strip light is disclosed. The joint support and strain relief is comprised of a cuff portion that defines a curved interior channel designed to cradle a power cord and a contiguous spade portion in the form of a thin, flat, generally rectangular plate. The strip light is typically secured to the spade portion with adhesive. The spade portion may have sidewalls to assist with the alignment of the strip light, and those sidewalls may have attached to their upper edges horizontally inwardly-extending tabs parallel to and above the bottom of the spade portion. The joint support and strain relief may also have tabs with holes or openings that allow the piece to be attached to a substrate.

Abstract: A waterproof adapter that connects strip light to a standard power cord, such that the power cord can then be routed to a power source. The adapter has an internal vertical barrier to separate power and ground leads, and gripping structures that help to retain the strip light within the adapter.

Abstract: An LED lighting kit comprises an extrusion (300), an LED strip (100), a tapered wedge (1500), and a mounting clip (1200). The extrusion itself may have a recessed linear groove of sufficient width and depth to seat the LED strip. The clip is sized and shaped to springably engage ledges (320) in a first channel (310) of the extrusion when the strip is mounted. In one aspect, two extrusions are butted end-to-end and are aligned by inserting the tapered wedge into the first channel of each extrusion prior to butting them together. The extrusion contains a second channel (315) that houses the LED strip. A translucent diffuser (900) is springably inserted into the second channel, thereby diffusing light that is emitted by the LED strip.

Abstract: A modular lighting system for use with shelving and a variety of other applications. A power track is adapted to be disposed within an upright support of a shelving unit.
