Abstract: A linear luminaire having high ingress protection includes a light-generating assembly and a channel. The light-generating assembly is an elongate, self-contained, sealed optical assembly that includes all elements necessary to generate light and to direct, focus, or modify the generated light in a particular way. Typically, the light-generating assembly would include an outer optical element and a light source positioned within a cavity of the body of the light-generating assembly. The outer optical element may be a lens, diffuser, or other such element. The light source may be a strip of LED linear lighting, a string of connected LED modules, or any other suitable device. The light-generating assembly may optionally include a second optical element, such as a lens or diffuser, that is supported within the body. The ends of the body of the light-generating assembly may be sealed by fitted endcaps, by polymeric resin, or by other means.

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 linear luminaire includes a three-sided enclosure with a top that is at least translucent and a pair of depending sidewalls spaced apart by the top. The three-sided enclosure may be extruded from a plastic or, in some cases, co-extruded with two different materials so that the pair of sidewalls can be made of an opaque material. The three-sided enclosure may be open along a bottom aspect. An elongate rigid printed circuit board (PCB) carrying LED light engines is installed between the pair of sidewalls in slot structure defined on respective inner faces. The PCB may carry connecting structure staggered along the length of its underside. The PCB may also carry circuit components on its underside.

Abstract: A linear luminaire is disclosed. The linear luminaire includes a channel, in which a strip of linear lighting is disclosed. The strip of linear lighting may have an individual optic positioned over each LED light engine. A set of louvers is provided. The set of louvers is arranged such that an individual louver is positioned over each one of the LED light engines. The individual louvers are generally cylindrical in shape. The individual louvers are connected by a web or platform that carries engaging structure allowing the set of louvers to snap or slide into the channel. The channel is covered with a channel cover, which has edges that extend out over at least a portion of the channel sidewalls, making it more difficult for dust and other foreign matter to enter the channel. The channel cover may be transparent.

Abstract: Encapsulated linear lighting with improved light diffusion is disclosed. The encapsulated linear lighting includes a channel and a long narrow strip of printed circuit board (PCB) with light engines disposed off-center on the PCB. The PCB is installed along a bottom inner surface of a sidewall of the channel so that the light engines are adjacent a bottom of the channel. The encapsulated linear lighting includes a covering that encapsulates and protects the PCB.

Abstract: Connectors for linear lighting are disclosed. These connectors are adapted to electrically connect two strips of linear lighting, or a single strip of linear lighting and an appropriate number of wires. At least the portions of the connectors that accept the strips of linear lighting have sloped ramps that provide strain relief to the strips of linear lighting. Additionally, pivoting connectors that allow their sides to rotate relative to one another are disclosed.

Abstract: A printed circuit board (PCB) is adapted to accept high-voltage, alternating-current (AC) power. Mounted on the PCB are two series of LED light engines. A first series of LED light engines is configured to illuminate during a first portion of the AC power cycle, and a second series of LED light engines is configured to illuminate during a second portion of the AC power cycle. The first portion and the second portion are different from one another. For example, the first series may be configured to illuminate during the positive half-cycle, and the second series may be configured to illuminate during the negative half-cycle. LED light engines of the first series and the second series may be interdigitated with one another on the PCB.
