Abstract: 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.

Abstract: Methods and systems for controlling compound ramps in LED luminaires and lighting circuits are disclosed. In a compound ramp, the light output of one set of LED light engines increases while the light output of another set of LED light engines decreases. During such a ramp, the methods and systems may control the total light output to keep it relatively constant. In some embodiments, the methods and systems may also control the color of the emitted light maintain ideal color characteristics.

Abstract: A linear luminaire includes a channel with a bottom and sidewalls that arise from opposite sides of the bottom. A printed circuit board (PCB) including a number of LED light engines is mounted in the channel, and may be mounted on stand-offs away from the bottom of the channel. A mounting bracket is connected to an underside of the channel bottom. The linear luminaire also includes a base that can serve as a raceway for wires and cable. The base also has a bottom and sidewalls, and attaches releasably to the channel by means of cooperating engaging structures on the mounting bracket of the channel and portions of the sidewalls of the base.

Abstract: Channels and channel covers for linear lighting are disclosed. The channels have an upper compartment for linear lighting and a lower compartment that may be used as a raceway, to engage parts, and for rear entry of wires. Endcaps for the channels may engage the lower compartment. Cover-lenses for linear lighting channels are also disclosed. The cover-lenses may include diffusing material and implement a thickness gradient in order to maximize the amount of diffusing material where the emitted light intensity is expected to be greatest. Diverging Fresnel features may be superimposed on the thickness gradient in order to counteract any converging effect of the thickness gradient and cause emitted light to spread more evenly.

Abstract: A flexible cover for a linear lighting channel is described, as are enclosures and luminaires using this kind of flexible cover. The flexible cover has sufficient flexibility to be bent or coiled to a bend radius of 6 inches (15.2 cm) or smaller, and can thus be coiled for shipping and uncoiled for installation. Typically, the cover is made of a polymer that is at least translucent. Covers may be made in various shapes, including lens and prism shapes, and channels may be made with sidewalls that make complementary shapes in order to engage with and retain the covers.

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.
