A retrofit kit for a lay-in troffer LED luminaire comprising two sets of connecting beams, with a first set being arranged in a parallel orientation and a second set of connecting beams oriented in a perpendicular manner with respect to each of the first set of beams. Each set of connecting beams are engaged to connected to each other by means of multiple coupling retainers and clamping hooks matched with each other to form a quadrangular bracket capable of containing the troffer. Compressible and extendable fastening means are further placed at the lateral sides of the troffer. And the troffer is connected to the ceiling through the allocation with the bracket by making fastening means aligned with the connecting holes on the first or the second sets of connecting beams that receive the fastening means.

The recessed luminaire (2) comprises: a housing (6) having an internal surface (18); and a light subassembly (8) engaged with a thermally conductive body (10), the light subassembly (8) having a first end (53) and a second end (54), wherein the first end (53) of the light subassembly (8) is pivotally secured to a pivot (16) arranged on, in, or proximate to the internal surface (18) of the housing (6). The thermally conductive body (10) is in thermal contact with the internal surface (18) of the housing (5). The recessed luminaire (2) further comprises a dehumidifier (90).

A runway-embedded flash lighting device includes, a body configured for embedding in a runway, a ceiling member with a flash emission window, a bottom cover member, a light guide member disposed in the flash emission window, and two or more flash emission windows. The light guide member is disposed in each of the flash emission windows and an inner surface of the ceiling member is provided with a site to be disposed with a LED flash light source below the flash emission window. The LED flash light source includes, an LED module, a frame-shaped attaching plate; and a lens member. The lens member is attached to a hollow portion in a frame of the frame-shaped attaching plate, and is configured to allow an emission surface of the flash emitted from the LED module to have a uniform illuminance distribution.

A UV ceiling light including a mounting box, a mounting board, driving power supply, a UV module, a grating component and a cover plate. There is a mounting space inside the mounting box, the bottom of the mounting box is provided with avoiding holes connecting to the mounting space, the mounting board is provided on the upper end of the mounting box in a dismountable way, and the driving power supply is provided inside the mounting space; the upper end of the UV module passes through the avoiding hole and extends into the mounting space, and the UV module electrically connects to the driving power supply; the grating component is provided on the lower surface of the mounting box, the grating component includes several separating plates that are horizontally circular and provided around the UV module, and each two adjacent separating plates form a light outlet in an enclosing way.

A recessed light fixture includes an LED module, which includes a single LED package that is configured to generate all light emitted by the recessed light fixture. For example, the LED package can include multiple LEDs mounted to a common substrate. The LED package can be coupled to a heat sink for dissipating heat from the LEDs. The heat sink can include a core member from which fins extend. Each fin can include one or more straight and/or curved portions. A reflector housing may be coupled to the heat sink and configured to receive a reflector. The reflector can have any geometry, such as a bell-shaped geometry including two radii of curvature that join together at an inflection point. An optic coupler can be coupled to the reflector housing and configured to cover electrical connections at the substrate and to guide light emitted by the LED package.

A lighting system includes an LED downlight mountable to a ceiling, a driver, and an insulation displacement connector (IDC). Light from the downlight can be faced downward to project light or upward to reflect light off of the ceiling. The driver has an input with a first voltage and an output with a second voltage, the second voltage being lower than the first and being provided through a wire system extending from the LED driver. The IDC connects the downlight to the wire system. The lighting system can be changed from a first to a second configuration by at least one of adding an additional downlight using a corresponding IDC or removing an existing downlight using a corresponding IDC. The second configuration does not significantly affect a desired output range of light from any downlight or any LED circuit of any downlight that remains or preexists from the first configuration.

Examples of the present disclosure provide a light distribution element, a light source module and a lamp, the light distribution element includes a light entry surface, a first light exit surface and a second light exit surface, the first light exit surface is configured to receive part of light entering the light entry surface and emit the part of the light entering the light entry surface; the second light exit surface is a reflective surface, and the second light exit surface is configured to receive part of the light entering the light entry surface and reflect the part of the light entering the light entry surface; and a direction of the light emitted from the second light exit surface is different from a direction of the light emitted from the first light exit surface, it can be used for key lighting and lighting ceiling areas respectively.

The present invention discloses a joinable lamp structure, which is made by joining two neighboring lamps through a joining component. A side cap is used to cover the exposed ends of the lamps. After the assembly, the present invention can be embedded inside the mounting slot of the ceiling or suspended below the ceiling.

A recessed enclosure (100) for a light source (01). The recessed enclosure (100) includes a housing (102) having a mounting fixture for fitting a light source (01) thereon. A lid frame (104) has an opening (106) configured thereon emitting light from the light source (01). The lid frame (104) includes a first gasket (108) provided in a first groove (105), configured on the lid frame (102). A transparent body (110) is nested with the first gasket (108) for reflecting light emitted by the light source (01). Retainer clips (112) are provided along the longitudinal edges of the first groove (105) to compress and seal the first gasket (108) to prevent ingress of dust and moisture through the opening (106). Three fasteners (114) securely attach the lid frame (104) to the housing (102).
