Abstract: Modular channels are disclosed. The channels include a pair of sidewalls and a channel bottom. The pair of sidewalls and the channel bottom are separate, modular, and connected at or proximate to the sidewall bottoms by complementary engaging structures carried by the parts. In some cases, an intermediate member may be placed in the joints between the bottom and the sidewalls. The intermediate member may be made of plastic or rubber, and typically has a constant cross section. It may be a tube or have a round or ellipsoid cross section. The sidewalls may have flanges for flush-mounting the channel in a wall or similar structure. The sidewalls and bottom may carry various channels for alignment with other channels or mounting on other structures.

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 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.

Abstract: Junction boxes and partitions for junction boxes are disclosed. The junction boxes have a central area for installation of a driver or another such component and at least one wrap-around compartment in which wire connections can be made. In many cases, the junction box may have two wrap-around compartments, often mirror images of one another, that provide separate spaces for high- and low-voltage wire connections. The interior walls or partitions that create the compartments may be carried by and arise from the base of a junction box, or they may be carried by a separate piece that inserts over the driver, fully encloses or caps it, and also carries partition portions to create fully-divided compartments when used in combination with a junction box base that has no partitions of its own.

Abstract: Assemblies are disclosed that allow a driver to be mounted in association with an electrical gang box. In one embodiment, the gang box has an opening in a bottom panel. The driver has a flange that is larger than the opening and a body that is smaller than the opening. The driver is inserted through the opening so that the flange rests on the interior surface of the bottom panel with at least a majority of the body of the driver extending outside of the gang box. In another embodiment, the gang box has an opening in a side or rear panel and an adapter mounts the driver outside of the gang box. These assemblies allow for the use of low-voltage and other types of electrical components while leaving space in the gang box for conventional electrical elements, such as switches and dimmers.

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: Connectors for linear lighting are disclosed. These connectors include one side with a slot adapted to accept a strip of linear lighting. The other side may have either another slot for a second strip of linear lighting, if two strips of linear lighting are to be electrically connected end-to-end, or a set of terminal blocks for connecting the strip of linear lighting to wires, such as a set of power leads. The slot has a set of contacts, spaced from one another, that make physical contact with solder pads or other such electrical connecting structures on the linear lighting. The terminal blocks have conductive cages to make contact with the wires. Both the set of contacts in the slot and pressor members in the cages are driven into engagement by sets of adjustable positioning members that bear on them.

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

Abstract: An in-ground channel for linear lighting is disclosed. In the channel, two upright sidewalls are spaced apart by a bottom. Each of the sidewalls has an inwardly-extending upper support flange proximate to an upper end. The inwardly-extending upper support flanges are aligned with one another on respective sidewalls. A shelf is mounted between the two upright sidewalls at a position below the inwardly-extending support flanges. The shelf divides the in-ground channel into an upper section and a lower section. The upper section houses linear lighting and the lower section provides a raceway. The channel has only a single mounting flange attached to one of the two sidewalls at a position level with the bottom. The channel typically also includes a cover adapted to engage the upper support flanges. The shelf may be removable, mounted via a pair of inwardly-extending lower support flanges, for access to the lower section.

Abstract: LED simulated neon with a reinforcing member is disclosed. The simulated neon has a flexible covering with a translucent upper portion and an opaque lower portion. At least the lower portion is filled with a transparent, flexible material. A channel is formed in the transparent, flexible material. Linear lighting is provided in the channel, along with a reinforcing member. The reinforcing member is shaped and oriented such that it can bend in the primary bending plane of the simulated neon but provides strain relief and at least partially restricts or interferes with bending in other planes. The reinforcing member may, for example, have a rectangular cross-section, wider than it is thick. It may be made of plastic or metal, and its thickness may vary depending on the material of which it is made.

Abstract: An elongate, flexible printed circuit board (PCB) has a central section that carries LED light engines and other components, and a pair of wings, one on each side of the central section, adjacent to the central section. The wings carry adhesive to secure the PCB to a substrate, and may be separated from the central section in some cases by fold or score lines. The LED light engines may be positioned on a first side of the PCB and electrically connected to one or more components on a second side of the PCB. Taken together, the wings may have the same width as the central section, or they may have a greater width.

Abstract: Linear lighting is disclosed. The linear lighting includes a narrow, elongate printed circuit board (PCB). A plurality of LED light engines are disposed on the PCB and are electrically connected to it. The PCB is divided physically and electrically into repeating blocks, which are physically in series with one another and electrically in parallel. A pair of conductors extends the entire length of the linear lighting. Each of the conductors has a service loop corresponding to the position of each of the cut points. A covering encapsulates the PCB and the pair of conductors. The service loops in the conductors provide for additional length of conductor when the linear lighting is cut at a cut point, so that the linear lighting can be connected to power.

Abstract: Printed circuit board (PCB) arrangements for linear lighting are disclosed. In one embodiment, an elongate, flexible PCB carries light-emitting diode (LED) light engines on one side of the PCB and components on the other. The components may be, e.g., resistors, current controllers, color controllers, or network interfaces. In another embodiment, two PCBs, each with components mounted on a single side, are connected together electrically and mechanically to function as one. In yet another embodiment, an elongate, flexible PCB has a central section that carries LED light engines and other components, and a pair of wings, one on each side of the central section. The wings carry adhesive to secure the PCB to a substrate.

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 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.
