An improved apparatus for conditioning the temperature of the air in a substantially confined space, such as a room, is disclosed. The conditioning system is complete and integrated in a portable unit suitable for insertion in a wall opening, such as a window. The operative elements are divided between two separate enclosures, each attached to a common structure, the support capable of resting on the window sill, with one such enclosure on each side of the wall. At least the heat exchanger conditioning room air is disposed in the enclosure in the room side of the wall. At least the compressor is segregated in the other enclosure, on the other side of the wall of the conditioned space. And both enclosures sit substantially below the sill line. Obstruction of the window opening is much reduced over prior art units. Installation is easier and safer. And the segregation of the compressor, which can be improved by sound and vibration dampening treatments, drastically reduces the noise level in the room produced by the system's operation.

A luminaire includes a housing, a light diffusion panel, a reflective surface, and a plurality of light sources. The light diffusion panel includes a light source aperture, an edge surface bounding the light source aperture, and an emission surface. The emission surface includes first and second emission surface sections. The second emission surface section is disposed on an opposite side of the light source aperture from the first emission surface section. The reflective surface is disposed on a side of the light diffusion panel opposite the emission surface. The light sources project light into the light diffusion panel through the edge surface. The light sources include first and second light sources. The first light source projects light into the light diffusion panel and through the first emission surface section. The second light source projects light into the light diffusion panel and through the second emission surface section.

A lighting system 1 for screened enclosures (2) wherein side edges (8) of an elongated housing strip (4) mount to a framework (3) of the screened enclosure using screen cable channels (21) located on a frame rail (5) of the framework.

Disclosed is a junction device for joining adjacent housing sections of a light fixture housing assembly, having a junction body structure formed from at least one junction body segment. A plurality of coupling units, each with at least one first boundary including at least one male portion or at least one female portion. The male and/or female portions are configured to enable each corresponding portion a first of the coupling units to receive the male portion of a second of the coupling units. Each of at least two of the coupling units including a first segment formed with the at least one junction body segment at respective first boundaries with the corresponding male or female portions extending therefrom. Each of the male and female portions is configured to be associated with a first locking structure to lock the female and male portions together to form the assembled light fixture housing.

A structural beam and light fixture for a walkable ceiling of a clean room is composed of an elongated channel and a lamp disposed in the elongated channel. The lamp is configured to direct light through the bottom side of the elongated channel. The structural beam and light fixture is attached to adjoining ceiling components and is configured to support a load applied to the adjoining ceiling components. The structural beam and light fixture, combined with other walkable ceiling components, define ceiling top and bottom sides that are flush.

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.

Various embodiments of the present invention provide a universal and multi-configurable light emitting diode (LED) flat panel light, a bracket configured for mounting the light in a variety of ways, a mounting kit for mounting the light in a variety of ways, and associated methods for mounting the light. In one embodiment, a mounting bracket is provided. The mounting bracket may comprise a bracket frame. The bracket frame comprises one or more notches configured to each receive a knob of an LED flat panel; a locking mechanism associated with each of the one or more notches, the locking mechanism configured to retain the protrusion/knob; one or more suspension wire receiving mechanisms, each suspension wire receiving mechanism configured to receive and retain a suspension wire for suspending the LED flat panel as a pendant light; and one or more junction mount securing mechanisms configured to have a junction mount secured thereto.

A display apparatus including an illumination unit having a first illumination unit including a first light source module, a second illumination unit including a second light source module, and a bracket located between the first and second illumination units to connect the illumination units to each other. The bracket includes a first body portion on which the first light source module is placed, a second body portion on which the second light source module is placed, and a connecting portion located between the first and second body portions to connect the body portions to each other. The connecting portion has a first distance from a first end of the first or second body portion and a second distance from a second end of the first or second body portion, and the second distance is greater than the first distance.

Said lighting device is made up of lighting elements (L1, L2, . . . , L20) arranged on a mounting board (PS1, PS2, etc.). The one or more boards are arranged so as to supply light with a predetermined coverage.

The boards comprise a plugging system (C1, C2, C3, P1, P2, P3) for connecting said lighting elements. The mounting of such a device using a threaded rod 7 makes it possible to obtain easy maintenance of the device of the invention. This device can easily be used to form striplights.

Use: Lighting of car parks, meeting rooms.

A retrofit trim lighting device is provided. In example embodiments, the retrofit trim lighting device comprises a bracket comprising an opening; at least one torsion spring secured to the bracket and configured to mount the retrofit trim lighting device within a recessed housing; a retrofit housing comprising at least one light engine; and an engagement element. The engagement element is secured to the retrofit housing through the opening of the bracket such that, when so secured, the retrofit housing and the bracket are rotatable relative to one another.
