In one embodiment, a recessable luminaire comprises two or more luminaire modules, each one of which comprising a recessable housing having opposed side walls. The luminaire further comprises an output element securable along and between these side walls to at least partially define an output of the luminaire, and opposed inwardly biased output coupling structures extending at least partially along respective side walls and adapted to receive and resiliently secure corresponding edges of the output element therein.

The present disclosure provides a light source module and a lighting device using the same. The light source module includes: a support member, to be disposed on a lighting device and provided with a first positioning portion; a light source mounting member, having a second positioning portion to be jointed with the first positioning portion through shape matching, where the light source mounting member has a bearing surface for disposing a light source electronic component; and a lens member, covering the bearing surface and connected to the support member in a positioned manner.

Provided is a kit for assembling a luminaire comprising a bendable reflective canopy and a plurality of frame sections which define a frame and a light exit window of the luminaire. The frame sections include a pair of opposing side sections with an engagement member and side sections. The reflective canopy comprises a pair of opposing edge portions, each edge portion engaging with one of the engagement members when assembling the luminaire. The opposing side sections are spaced by the further side sections such that the reflective canopy is bent when the edge portions are engaged with the engagement members so as to cause the reflective canopy to arch over the light exit window. Solid state lighting elements are mounted on one of the side sections such that at least a part of the light emitted is redirected by the arched reflective canopy towards the light exit window.

Alternatively, the first coupling region (3) is provided on the side of one of the side walls (21) and the second coupling region (4) is provided on the side of the other of the side walls (22) as viewed in the longitudinal axis direction (L). In this case, the lighting strip lamp (6) and the unit (7) are both releasably mechanically coupled to the coupling regions (3, 4).

A luminaire includes a back plate and a wire cover. The back plate includes a first tab that defines a tab receiving cavity. Further, the first tab includes a first mating feature formed therein. The wire cover includes an inner surface that defines an electronics cavity, an outer surface that defines a light source mounting platform, and a second tab. The second tab includes a second mating feature that is complementary to the first mating feature. The second tab of the wire cover is disposed in the tab receiving cavity defined by the first tab of the back plate to removably couple the wire cover to the back plate. Further, the second mating feature of the second tab engages the first mating feature of the first tab to releasably lock the wire cover to the back plate.

The present invention provides a U-shaped luminaire, comprises a lamp head module, a first glass tube, a second glass tube, a first light source board, a second light source board and a light transmission module, said lamp head module engaging said first glass tube and said second glass tube respectively, said first light source board being located within said first glass tube, said second light source board being located within said second glass tube and said light transmission module engaging said first glass tube and said second glass tube respectively.

The present invention discloses a panel light mounting structure, a panel light and mounting method thereof. The panel light mounting structure comprises a fixing slot disposed on the back of the light body and a mounting bracket to snap-connect with the matching fixing slot. The present invention adopts a sliding and snap-in method to match and connect the panel light body with the mounting bracket. The installation is easy and fast, and the ceiling-mount effect is excellent. In addition, the present invention may also achieve the blinds operation during the panel light installation process.

A trellis lighting system that includes at least one lighting and support assembly. The at least one lighting and support may include a cover, a heat sink, and at least one light emitting diode (LED) strip. The cover permits light to pass there through and includes a body extending a first length. The heat sink is configured to couple to the cover and may include a body extending a second length. The body may include an outer surface, an inner surface defining a lumen that extends through the body, a plurality of outer fins coupled to the outer surface, and a plurality of inner fins coupled to the inner surface. The at least one LED strip may be configured to be coupled to the body of the heat sink along the second length thereof so as to dissipate heat generated by the at least one LED strip.

A light assembly includes a heat pipe having a first condenser portion and a first evaporator portion. The heat pipe includes a longitudinally extending wall. A plurality of light sources are disposed at least partially around and thermally coupled to longitudinally extending wall at the first evaporator portion of the heat pipe. A first heat sink housing receives the first condenser portion of the heat pipe.

A lighting system includes an upper housing supporting a light engine, and a diffuser coupled to the upper housing. The diffuser may be monolithic, i.e. formed of a single material as a single piece without joints or seams where separate components are joined. The monolithic diffuser may be formed by an additive manufacturing process, for example 3D printing. The diffuser may couple to the upper housing with a tool-less connection. The portion of the tool-less connection defined by the diffuser may be formed by the additive manufacturing process. The lighting system may further include a lens coupled to the diffuser opposite the upper housing with a lens retaining ring.
