The lampshade includes: a shade body, including a cover member and a top plate covered on the cover member, the top plate including a notch, the notch being open at a periphery of the top plate, the shade body further including a slot, the slot being in communication with the notch, the slot having a width larger than a width of the notch, the diametric dimension of the flange being larger than the width of the notch; wherein the slot is configured to receive the flange, the notch is configured to receive the body portion, and the top plate is configured to be engaged between the substrate and the flange.

The present invention relates to lighting fixtures which are mounted into architectural finished surfaces such as ceilings, walls and floors, and is applicable to new installations as well as the renovation of existing surface-mounted fixtures. One embodiment relates to a modular lighting device for retro-fitting to an existing lamp housing which is flush mounted or countersunk into an opening of a ceiling or interior surface of a building, the modular lighting device comprising a lamp-fitting configured for receiving a light source and configured for attachment to the existing lamp housing, and reflector for reflecting and/or modifying light from the light source, the reflector comprising a narrow top section configured for attachment to said lamp-fitting, and a wider bottom section for covering said opening.

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 a housing container and an axial fan. The fan has a fan cavity including air diversion mechanism to direct air from the fan cavity toward the lighting and fan components. The inventions include an airflow surface to direct air existing the fan cavity along an LED light fixture. Moreover, disclosed embodiments include one or more UV light sources which irradiate contaminants as air flows through the ceiling tile.

A trim member for a lighting device module includes an annular body having a first end portion that is connectable to a housing of the lighting device module and has a light receiving opening, and a second end portion opposite to the first end portion. The second end portion has a light emitting opening and is configured to be positioned outside of the housing of the lighting device module. A first curved or tapered surface extends from the light receiving opening toward the light emitting opening, and has a diameter that increases toward the light receiving opening. A second curved or tapered surface extends from the first curved or tapered surface to the light emitting opening, and has a diameter that increases toward the light emitting opening.

An underwater lighting apparatus includes a cofferdam having a cofferdam electrical connector rigidly mounted within the cofferdam at an inner end; a lighting unit sized and shaped to be mounted within the cofferdam and having a lighting unit electrical connector rigidly mounted at an inner end; wherein the lighting unit electrical connector is sized and shaped to directly connect with the cofferdam electrical connector to form a rigid connection between the cofferdam and the lighting unit. The lighting apparatus is beneficial in that both the cofferdam electrical connector and the lighting unit electrical connector are rigidly mounted.

A lighting system configured for daylight emulation. The system includes a plurality of light sources for generating a daylight-emulating output light spectrum and a ventilation element for generating a simulated breeze to artificially emulate conditions in an outside environment of an enclosed structure in which the lighting system is disposed. The system also includes a controller for dynamically controlling at least one of the intensity, directionality and color temperature to emulate sun position for at least one of a geography and time of day. The controller also controls the generated simulated breeze of the ventilation element to be one of a cool breeze and a warm breeze to artificially emulate the outside environment in correspondence with the artificially emulated daylight spectrum. The system further includes a networking facility that facilitates data communication with at least one external resource.

Disclosed is a night downlight, including a plastic housing, a light source plate, a reflective cup, and a light guide sleeve. The plastic housing is provided with an opening, and the light source plate is arranged on an inner side of the plastic housing opposite to the opening. The light source plate is provided with a first light source and a second light source. One end of the reflective cup abuts against the light source plate. The light guide sleeve is arranged between the other end of the reflective cup and the plastic housing. The light guide sleeve is in snap-fit with the reflective cup. The snap-fit design of the light guide sleeve and the reflective cup allows replacement of the small component rather than replacement of the whole face ring when the snap-fit structure fails, thereby effectively reducing waste in repair and replacement.

A luminaire comprising a heat spreader and a heat sink disposed around and thermally communicates with the heat spreader. The heat sink forms a trim plate configured to be disposed completely external of a can light fixture or an electrical junction box. The luminaire also includes an optic securely retained relative to one of the heat spreader and the heat sink on one side of a plane defined by a lower surface of the trim plate and extends to the other side of the plane defined by the lower surface of the trim plate, as well as a light source disposed on the heat spreader and comprising a plurality of light-emitting diodes (LEDs). The plurality of LEDs are positioned entirely on one side of the plane defined by the lower surface of the trim plate. The light source is in thermal communication with the heat spreader.
