Linear lighting for which the light output is selectable among two or more predetermined options using onboard circuitry is disclosed. In this linear lighting, the onboard input-side power circuit for the linear lighting has multiple branches. One branch of the input-side power circuit directs all power applied to its solder pad directly to the LED light engines. The other branches of the input-side power circuit have components in them that moderate or control the effective light output of the LED light engines. For example, each circuit branch that offers a reduced light output may include a pulse-width modulation (PWM) oscillator circuit that reduces the duty cycle of the LED light engines. A working embodiment may have, e.g., one circuit branch that produces 100% of rated light output, one circuit branch that produces 50% of rated light output, and one circuit branch that produces 25% of rated light output.

Lighting circuits using LED light engines and strips of linear lighting using these circuits are described. The lighting circuits are designed to produce different levels of light output at least in part using onboard components. In some embodiments, the circuit contains several current-setting elements, such as resistors, which are coupled to their own terminals such that the light output of the lighting circuit is determined by which of the terminals are connected to power. In other embodiments, a transistor in the lighting circuit may be adapted to allow or prevent current flow in the circuit based on a control signal applied to its gate. The circuit thus has separate power and control signal lines, and an external device, such as a pulse-width modulation signal generator, may be applied to the control signal line to modulate the light output.
A channel system that includes a first channel section, a second channel section, and a hinge joint between the first and second channel sections is disclosed. The hinge joint allows the first channel section to fold against the second channel section for storage and shipping of the channel system. In one embodiment, the hinge joint itself includes a hinge member that extends between the two channel sections and bends hingedly to allow movement and two intermediate endcaps, which cap the channel sections on either side of the hinge joint. The hinge joint may be designed to “snap back” to a fully extended position. Mechanical securement structure may be added to the first channel section and the second channel section to improve force and retention during the “snap back” movement.

A drive circuit for an LED luminaire is disclosed. The drive circuit includes one or several series of LED light engines. A voltage source with a regulator is connected to the series of LED light engines to forward-bias the light engines. The circuit also includes an integrated circuit driver, which may drive the series of LED light engines using, e.g., pulse-width modulation (PWM). The circuit also includes a feedback circuit connected to the cathode end of the series of LED light engines. The feedback circuit receives a remainder voltage and creates a feedback output signal that upregulates or downregulates the regulator of the voltage source to keep a minimum operating voltage on the integrated circuit driver and also to compensate for variations in forward voltages among LED light engines in the series. A switching element, such as a bipolar junction transistor, protects the driver from high voltages.
A linear luminaire includes a channel with a bottom and sidewalls that arise from opposite sides of the bottom. The channel has an upper compartment and a lower compartment, the sidewalls being of a shape and extent such that at opposite ends of the channel, the upper compartment overhangs the lower compartment in a longitudinal direction. An elongate, rigid printed circuit board (PCB) is mounted in the upper compartment of the channel, aligned along the longitudinal direction, the PCB extending to each of the opposite ends of the channel in the upper compartment and having one or more LED light engines mounted thereon. The PCB may be mounted on stand-offs, such that it is above the bottom of the channel and defines the boundary between the upper and lower compartments. The overhung upper compartment creates a cableway space when two linear luminaires are abutted end-to-end or are adjacent.

Methods for controlling power consumption and temperature in an LED luminaire are disclosed. The LED luminaire has one or more sets of LED light engines disposed on a printed circuit board (PCB), some or all of which are activated in response to an instruction or set of instructions. The instruction or set of instructions are processed to derive an indication of power consumption for each of the one or more sets of LED light engines. Power allocations for the one or more sets of LED light engines are adjusted to meet targets. This can be done by, e.g., ramping up or down the duty cycle of active sets of LED light engines by a uniform factor until the targets are met. Temperature control methods similarly ramp down the duty cycle of active sets of LED light engines uniformly over time if the measured temperature of the PCB exceeds limits.

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.

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.

High-voltage linear lighting with conductor service loops
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.

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.
