A lighting system includes a linear luminaire having a length and a width, where the length is longer than the width. Further, the lighting system includes at least two rigid pendants that are configured to suspension mount the linear luminaire from a mounting surface. Each rigid pendant is coupled to the linear luminaire via a clevis such that a joint between the rigid pendants and the linear luminaire is a clevis swivel joint that allows the linear luminaire to swing along the length to meet a seismic requirement while preventing a tilting of the linear luminaire along the width.

A lighting system has a set of linear lighting elements and a set of suspension elements. Each suspension element comprises an upper fixing part and a lower connection part facing downwardly for making electrical and mechanical connection to an upward facing connector on a top face of an end of a linear lighting element. This enables a simple a push fit connection of the lighting elements to the suspension elements, after they have been suspended from a support structure above them.

A sound lamp includes an illuminating device including a circuit board, a single-piece controller, and sixteen light emitting members. The single-piece controller has sixteen legs. Each of the light emitting members has a first end and a second end. The first ends of the light emitting members are connected in parallel. The second end of each of the light emitting members is electrically connected with one of the legs of the single-piece controller. The single-piece controller controls lighting sequences of the light emitting members. Thus, the single-piece controller controls the light emitting members, such that the light emitting members are brightened gradually and dimmed gradually at different cycles, so as to simulate a real flame of an oil kettle.

A fastening device for fastening lighting devices to T-shaped profiles of a false ceiling comprises a base wall on which the lighting device may be fastened. The fastening device also comprises two longitudinal side walls rigidly connected along the longitudinal sides of the base wall and a plurality of fastening elements arranged along the longitudinal sides of the base wall, wherein the fastening elements can be folded in the direction of the base wall, to engage the fastening device with the T-shaped profile. The fastening device also comprises at least two spacer elements arranged between the base wall and a respective longitudinal side wall to provide a gap between the side walls and the base wall. This gap provides a passage for the electrical connections between the lighting device and a power supply source located above the false ceiling.

An indoor soilless plant cultivating system. The system has a plurality of (a) stationary light posts, (b) plant growth towers, and (c) irrigation means. Each post is adapted to illuminate a predetermined sector of an indoor facility in accordance with a predetermined illumination signature. Each tower is rotatable about a substantially vertical axis in accordance with a predetermined timing sequence so as to be exposable to the light generated at any given time by one or more of the light posts and that are arranged by at least one module defining a module darkened interior region within which plants being instantaneously positioned receive a sensation of nighttime. The irrigation means supplies the plants being cultivated in each of said towers with a nutrient-rich solution.

A modular lighting system for providing light in various areas includes one or more canopies, a set of bars, a set of hangers for supporting the bars from canopies and, optionally other supports, a set of pendants with light emitting elements and a set of hangers for supporting the pendants from the bars. The bars include two segments with conductive rails disposed or imbedded in their inner surfaces. The hangers have one or two rods and bases shaped and sized for mounting on the bars with the rods contacting the conductive rails. The hangers and bars cooperate to allow the hangers to be placed anywhere along the bars. Pendants can be hanged on the bars singly, or in clusters. In this manner systems can be formed easily and quickly to achieve systems having various esthetic and utilitarian configurations.
