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 drivers to be placed in a junction box without having to pull wires through holes or openings. Typically, the base is open along one long sidewall, with the cover being L-shaped to complete the enclosure. Various mounting mechanisms are disclosed for securing drivers within junction boxes.

Junction box for LED drivers

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.

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. The driver has a groove or channel, and an electrical element, such as a switch, is sized to fit within the groove.

Light fixture

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.

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, and a filter may be connected to each of the LED light engines. 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.

Junction boxes for enclosing and making electrical connections to multiple 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 drivers to be placed in a junction box without having to pull wires through holes or openings. Typically, the base is open along two sidewalls, with the cover being U-shaped to complete the enclosure. Various mounting mechanisms are disclosed for securing drivers within junction boxes.

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.

LED driver systems adapted for gang boxes

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.

Power connectors for linear lighting

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.
