Flanges extending from the bottom of the channel section are secured to a wall stud or ceiling joist and end modules are secured to the ends of the channel section. LED strips are secured onto the spaced apart sidewalls inside the channel section and connected to appropriate wiring through one of the end modules. A channel cap is secured across the top of the end modules and foam inserted into the channel section. Drywall is laid to the edges of the device, is spackled and painted. The foam is removed and the lens secured over the channel section.

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: Junction boxes for enclosing and making electrical connections to multiple 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 two sidewalls, with the cover being U-shaped to complete the enclosure. Various mounting mechanisms are disclosed for securing drivers within junction boxes.

Abstract: A system for replacing linear fluorescent lamps with LED modules in a cabinet sign includes an LED module support structure. The LED module support structure may be attached to the raceways of the cabinet sign or to the sockets formerly used for mounting fluorescent lamps between the raceways.

Abstract: A system and method for providing light to a plant with a life cycle that includes a seedling growth period, a vegetative growth period, and a flowering growth period. Illumination to the plant is provided with an array of LEDs that contains red LEDs, blue LEDs and white LEDs. During the seedling growth period, no red LEDs are illuminated. Blue and white LEDs are lit, wherein the blue light is more intense than the white. During the vegetative growth period, white and blue LEDs are lit, wherein the white light is more intense than the white. During the flowering growth period, red and white LEDs are lit, wherein the red light is more intense than the white light. The change in coloring and intensity has beneficial effects during each growth period and at the same time inhibits insects.

Abstract: Systems, software, and methods are provided for efficient, dynamic lighting control. In an embodiment, a two-channel LED lighting system is dynamically controlled to emulate dimming of an incandescent fixture. In an example, a lighting fixture may include red, green, blue, and white emitting LED modules. The lighting fixture may be controlled such that it produces generally white light from about 2150K candle light color to 5500K daylight white color with only 4 LEDs. Furthermore, the white LED may be controlled such that the white LED CRI is approximately 95 to ensure optimal results when mixed with red and green. In another embodiment, a dynamic two-channel LED lighting system is controlled to emulate dimming of an incandescent fixture. Specific dimming protocol can allow for efficient dimming which helps minimize the height of a linear light fixture and maintain diffusion with multiple colored point sources at minimal pitch.

Abstract: An LED high bay light comprises a plurality of LED illuminant engines arranged abreast and alternately; each of the LED illuminant engine comprises an LED strip-shaped illuminant and an optical lens set covering the LED strip-shaped illuminant; the optical lens set comprises a plurality of strip-shaped optical lenses arranged conterminously; and two adjacent strip-shaped optical lenses are connected to each other through a mutual cooperation of the stepped spigots arranged oppositely. Each illuminant engine thereof adopts a structure of strip-shaped optical lens set with multiple sections, greatly reducing the difficulty in making molds and the cost for manufacturing parts.

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: A replacement LED insert module for retrofitting a pre-existing shoe box parking lot light. The module includes a plate into which an array of LED light fixtures capable of being operated directly from an AC power supply are mounted. The module is configured for attachment to a flange in the pre-existing shoe box parking lot light after the innards of the pre-existing light (bulbs, any reflectors, ballasts, etc.) have been removed.

Abstract: An LED lighting system is provided for connection to a variable power source providing input power, the LED lighting system having at least one power analyzing and processing circuitry connecting to the variable power source, and being configured to identify one or more characteristics of the input power, where the characteristics are selected from amplitude, frequency and pulse width of the input power, compare one or more of the characteristics of the input power to preset control criteria either in hardware or software or both to yield a comparison result, and then control the current control circuitry according to the comparison result.

Abstract: A heat dissipating LED light bar which may be used as part of a complete retrofit system for a variety of linear fluorescent light fixtures. The LED light bar comprises an elongate channel member which is preferably fabricated from extruded aluminum. In addition to the channel member, the LED light bar comprises a high-efficacy set of LEDs, which are preferably provided in the form of an elongate LED printed circuit board (PCB) or strip mechanically bonded to the channel member.
