PRINTED CIRCUIT BOARD AND COMPONENT ARRANGEMENTS FOR LINEAR LED LIGHTING
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.
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.
A power and control assembly is disclosed. An LED driver (12) is sized and adapted to fit within a single compartment of an electrical gang box (16), such as a two-gang box. An alternating current (AC) dimmer (14) 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 (34, 35) 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. 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.
F21S 4/22 - Lighting devices or systems using a string or strip of light sources with light sources held by or within elongate supports flexible or deformable, e.g. into a curved shape
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.
