The present application relates to a lighting field and discloses a lamp installed through screwing, and a lamp body. The lamp installed through screwing includes a lamp body and an installing bracket. The lamp body is provided with a first fastening part thereon. The installing bracket is provided with a second fastening part thereon. The first fastening part is configured to be inserted into the second fastening part, and the lamp body is screwed, and the first fastening part rotates to fixedly fit the second fastening part. The first fastening part fits the second fastening part through screwing, thereby achieving a quick installation and disassembly.

A baffle component for a luminaire includes a portion of opaque material that forms a front surface and a back surface as major surfaces. The front surface includes multiple ridges. The material also includes a top surface and a bottom surface, and a first end surface and a second end surface. The first end surface includes a first coupling feature, and the second end surface includes a second coupling feature that is configured to engage the first coupling feature of a second baffle component that is substantially identical to the baffle component. A baffle for a luminaire includes a plurality of such components. The baffle components engage with one another, with the first coupling feature of each of the baffle components engaging with the second coupling feature of another of the baffle components, to form a shape that surrounds a central opening of the luminaire.

A LED driver boxes for luminaires or LED lighting systems installed in applications where the building is pre-existing, and luminaires are retro-fitted to the space with great advantages in convenience is described. Driver box applications where luminaires are installed in a new construction where the ceiling has yet to be installed/built is easy. Driver boxes may be used where the ceiling is already built and for ease of installation and maintenance, the contractor may want to choose an option where the luminaire has easily accessible electronic components. The LED Driver Boxes provide a safe, clean, and rigid method to maintain the electronics by separating line voltage from DC voltage and electronics.

A lighting fixture includes a housing, a first light source, a light guide plate, and a second light source. The housing has an inner cavity and a mounting hole, the mounting hole communicates the inner cavity with an external environment of the housing, the light guide plate is installed in the mounting hole. A side of the light guide plate faces the inner cavity, the other side of the light guide plate faces an outside of the housing. The second light source projects second light to the light guide plate, the second light is capable of being projected to the outside of the housing through the light guide plate. The first light source projects first light, and is configured such that the first light is projected to the outside of the housing through the light guide plate, and the housing is a non-light-transmitting housing.

A lighting arrangement operable to emit light is disclosed herein. The lighting arrangement can include a mounting bracket and a luminaire. The mounting bracket can have first and second bracket portions positioned about a central longitudinal axis of the mounting bracket. The mounting bracket can also include at least one pair of telescoping shafts interconnecting the first and second bracket portions. The mounting bracket can also include at least one spring positioned to bias the at least one pair of telescoping shafts to an extended configuration. The luminaire can have at least one spring member selectively engageable with at least one shaft of the at least one pair of telescoping shafts to selectively interconnect the luminaire and the mounting bracket.

An apparatus for providing a light source to a building includes a lighting panel that has a housing. The housing includes an outer wall having a front surface and a rear surface. The front surface defines a cavity having a light source therein. The apparatus further includes a galvanized steel cover that is securable to and configured to conform to the rear surface of the housing.

Controlled environment light fixture configurations include an LED light source. The light fixtures can be installed and removed from below the ceiling. The light fixture can be installed and removed without opening the lens frame of the light fixture. The light fixture includes a sealed housing and seals to the ceiling when installed. The light fixtures are provided in exterior dimension sizes that allow the fixtures to be installed in a variety of controlled environment ceilings in recessed configurations. The lower surface exposed to the controlled environment is free of welds and grinds in order to provide a corrosion resistant surface.

A light fixture including a light source having an optical axis and a housing having an inner housing and an outer housing. The outer housing pivots on the inner housing and the light source is coupled to the outer housing for pivotal movement with the outer housing relative to the inner housing to move the optical axis relative to the inner housing. A retainer coupled to the housing and a portion of the retainer is movable in a direction toward the outer housing to inhibit movement of the outer housing relative to the inner housing to hold a position of the optical axis.

A light fixture including a housing having a longitudinal axis, the housing configured to be received in an aperture of a ceiling. A flange extends from the housing. A clamp is movable relative to the housing and the flange in a direction along the longitudinal axis toward the flange. The clamp includes a first clamping surface and a second clamping surface, the second clamping surface spaced an offset distance from the first clamping surface measured along the longitudinal axis. The first clamping surface is configured to clamp the ceiling between the first clamping surface the flange when the ceiling has a first thickness and the second clamping surface is configured to clamp the ceiling between the second clamping surface and the flange when the ceiling has a second thickness greater than the first thickness.
