A luminaire comprising a housing, a light-emitting optic attached to the housing, and a cavity between the housing and the light-emitting optic. A circular acoustic panel is attached to a perimeter of the housing and being fully circumferential around the light-emitting optic.

A device comprising an organic light-emitting diode comprising an organic layer sequence, a radiation exit area and an encapsulation, wherein the organic layer sequence comprises at least one radiation-emitting region which generates electromagnetic radiation in the spectral range from infrared radiation to UV radiation during operation, and wherein the encapsulation forms a seal of the organic layer sequence against environmental influences, at least one touch-sensitive operating element, wherein the at least one touch-sensitive operating element comprises at least one touch sensor, wherein the device is flexible.

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 dynamic acoustic jacket device and a dynamic acoustic jacket system, that includes a single piece of material folded into acoustic jacket for covering a lighting fixture, using locking devices or the cut away portion of the device, to quickly and easily install the acoustic jacket over suspension cables so that the acoustic jacket can be lowered and raised over the lighting fixture without the need to be attached thereto.

The invention relates to a connection system for establishing a detachable electrically conductive connection, including a female connector and a male connector compatible therewith. The female connector includes a socket with annular concentric contact openings and contact elements arranged within the contact openings. The male connector includes a plug with contact elements which can be inserted into the contact openings of the socket. Ferromagnetic elements are arranged concentrically around the socket or the plug, the ferromagnetic elements of the male connector and of the female connector having mutual attraction in order to generate a retaining force between the two connectors.

A lighting apparatus includes a driver, an elongated housing, an extending connector, a light source and an extension module. The driver converts an external power source to a driving current. The elongated housing has a lighting area, an extension area and a light opening. The extending connector has a holder and an electrode connecting to the driver. The holder is placed in the extending area of the elongated housing. The light source is attached to the lighting area for generating a first light escaping from the light opening. The extension module is attached to the holder of the extending connector to electrically connect to the driver via the electrode.

A ceiling connector assembly for mounting an article includes a ceiling connector configured to present an article-mounting end region below a downward facing ceiling surface, a canopy structure for locating on the mounting end region and configured to cover, at least in part, the mounting end region in a covering position, the canopy structure and the mounting end region each respectively including at least one first mounting structure and at least one second mounting structure, wherein when the first and second mounting structures are configured to enable the canopy structure to be removably mounted on the mounting end region in the covering position.

Disclosed embodiments relate to a combination axial fan and LED lighting system configured to fit into the footprint of a standard ceiling tile. Disclosed embodiments further include ceiling tiles with a built-in fan and/or LED lighting. The disclosed systems may include one or more UV-C light sources which irradiate contaminants as air flows through the UV-C unit. The UV-C unit is mounted on either a universal mounting mechanism or a mobile support unit to provide mobility to the UV-C unit.

A plant growing lamp includes a lighting unit and a hanging unit. The lighting unit includes a control box and a sliding part, and the hanging unit includes connection lines and a rope ratchets. Cables such as the rope ratchets and the connection lines can be roughly pulled straightly and fully by weight of the lighting unit. The rope ratchets can be pulled to adjust a distance between the lighting unit and the hanger, so as to change an interval between a lamp of the lighting unit and the plants under the lighting unit, thereby appropriately adjusting light intensity for plant growth to prevent from burning the plants.

A tension-mounted support lighting system provides visually stimulating flexile, lighting housed within an unconventional silicone lens. The system offers flexible installation and conceptual yet functional design. The lighting strip bends up and down giving it the unique ability to traverse open spaces wall to wall, wall to ceiling, or floor to ceiling. Various optional components allow customization and control for an ideal outdoor lighting system.
