A modular troffer-style fixture particularly well-suited for use with solid state light sources. The fixture comprises a reflector that includes parallel rails running along its length, providing a mount mechanism and structural support. An exposed heat sink is disposed proximate to the reflector. The portion of the heat sink facing the reflector functions as a mount surface for the light sources. The heat sink is hollow through the center in the longitudinal direction. The hollow portion defines a conduit through which electrical conductors can be run to power light emitters. One or more light sources disposed along the heat sink mount surface emit light toward the reflector where it can be mixed and/or shaped before it is emitted from the troffer as useful light. End caps are arranged at both ends of the reflector and heat sink, allowing for the easy connection of multiple units in a serial arrangement.

A luminaire having a substantially two-piece housing with a first portion and a second portion, for example a cover and a base. The cover receives one or more control components. The base receives a light emitter assembly and the control component assembly is operatively connected to the lighter emitter assembly to control the light output therefrom. A lens assembly can be connected to the bottom of the base. Different mounting components can be connected to cover to connect the luminaire 10 to a support.

A lighting fixture and method of providing lighting is provided herein that utilizes both direct and indirect light sources. The direct and indirect light sources can be provided in arrays of light emitting diodes (LEDs) oriented along desired axes. In some versions, the light fixtures described herein include a direct lighting array having one or more LEDs oriented to project light downwardly and an indirect lighting array having a plurality of LEDs oriented to project light in a transverse direction. Further, the light fixtures can include an indirect lighting member configured to be illuminated by the plurality of LEDs of the indirect lighting array. Additionally, or alternatively, the light fixtures described herein can include one or more controllers that are configured to independently operate the direct and indirect lighting arrays. Moreover, the indirect lighting array can be configured to emit light in a plurality of colors to visually convey information.

Embodiments include a lighting assembly includes an elongate gasket body formed of a resilient, optically transmissive material. The gasket body includes a light source cavity at least partially defined by a light transmission portion and an attachment channel configured to attach the gasket body to a mount. A light source is disposed in the light source cavity. Other embodiments include securement ring including a clamp portion and a lighting assembly portion. The clamp portion includes first and second segments, each being semiannular in shape and curving between first and second ends, the first end of the first segment coupled to the second end of the second segment and the second end of the first segment coupled to the first end of the second segment to collectively form an aperture. The lighting assembly portion includes a first and second segments, each being semiannular in shape and including a light source.

A light fixture includes a housing, and a lighting module. The housing defines first and second portions. The second portion defines a window. The lighting module is at least partially disposed in the second portion. The lighting module includes a submount, a plurality of light emitting diodes, a lens cover, and an encapsulating material. The plurality of light emitting diodes is coupled with the submount and is configured to project light through the window. The lens cover includes an exterior surface and overlies the plurality of light emitting diodes and the submount such that the lens cover and the submount define an interior therebetween. The encapsulating material substantially fills the interior.

A ceiling fan assembly or similar air-moving device can include a motor for rotating one or more blades to drive a volume of air about a space. The ceiling fan assembly can include a motor assembly and a light kit. The light kit can include a light frame and a light glass holder. The light frame can selectively couple to the light glass holder by a threaded connection. The light kit, motor assembly, or between the light kit and motor assembly can further include one or more sealing or deflecting components.

A suspension arm assembly including at least three horizontally aligned members relatively rotatable about each other. Each adjacent pair of members are connected to each other by a joint. At least one conduit extends along the at least three horizontally aligned members, with the at least one conduit being routed horizontally along the horizontally aligned members and not being located within a periphery of the at least three horizontally aligned members.

Mounting boxes for overhead beams, such as purlins, of a building are described. The mounting box may include a front side that is designed to attach to a lateral side of the beam, an upper portion bottom that may rest on the horizontal beam, and a lower portion bottom that may have or be connected to a lighting socket or other electrical device.

Embodiments herein relate to high output LED light sources with heat sinks. In an embodiment, a high-output LED light source is included having at least one LED; a circuit board, wherein the at least one LED is mounted on a first side of the circuit board; and a coil shaped heat sink, wherein the coil shaped heat sink is thermally bonded to a second side of the circuit board. In an embodiment, a high-output LED light source is included having at least one LED, a circuit board, wherein the at least one LED is mounted on a first side of the circuit board and a continuous flat wire heat sink. The continuous flat wire heat sink can be soldered to a second side of the circuit board and the continuous flat wire heat sink can be oriented perpendicular to the circuit board. Other embodiments are also included herein.

A light fixture, comprising a main body box (1), a guide rail head (2) positioned above the main body box (1) and capable of rotating relative to the main body box (1), and a light barrel (3) positioned on at least one side of the main body box (1) and capable of swinging up and down relative to the main body box (1), wherein a radiator (32) and a first light source (33) are arranged in the light barrel (3); the main body box (1) comprises a main body box top cover (11), a main body box bottom plate (12) and a main body box side plate (13) connected between the main body box top cover (11) and the main body box bottom plate (1); and the guide rail head (2) is pivotally connected to the main body box top cover (11), and the light barrel (3) is pivotally connected to the main body box side plate (13). The guide rail head of the light fixture can rotate in a horizontal direction relative to the main body box for adjustment, and the light barrel of the light can swing in a vertical direction relative to the main body box for adjustment, such that the irradiation angle and the irradiation range of the light barrel can be adjusted and various lighting requirements can be met.
