A combination axial fan and LED lighting system configured to fit into the footprint of a standard ceiling tile. The system includes 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 invention includes an airflow surface to direct air existing the fan cavity along an LED light fixture.

An illumination apparatus includes a surface rim, a rotation ring, a light holder and a retractable tube. The surface rim has a rim cover, and a rim wall protruding from the rim cover and defining a light opening. The rotation ring is held by the rim wall to be rotatable along an axis of a center of the light opening. The light holder is used for support a light source. The light holder is fixed to the rotation ring by two rotation axles so that the light holder is capable of orienting a light source in a plurality of angles with respect to a plane of the rotation ring. The retractable tube has an optical cover, such that a distance between the optical cover and the light source is adjustable.

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 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.

According to an aspect of this disclosure, a ventilation and lighting system including a main housing having an inlet opening and a discharge opening, a blower and motor assembly disposed within a housing and operable to move air through the inlet and outlet, a grille configured to be located at the inlet opening, the grille having a cavity and a plate defining a plurality of apertures through which air may move, and one or more lighting elements arranged within the cavity and an optical component covering the cavity. The system is arranged such that light developed by the one or more lighting elements mixes within the cavity and transmits through the optical component covering the cavity, and the system further includes a controller that coordinates operation of the blower and motor assembly and the one or more lighting elements from a remote location.

The downlight apparatus includes a surface rim, a rotation bracket, a bowl housing and a light source. The surface rim has an rim edge and a lateral wall. The rotation bracket includes a bracket body and two arms. Each arm has an arm bottom and a arm top. The rotation bracket is attached to the lateral wall. The bowl housing has a bowl edge. The bowl edge defines a light opening. The arm tops of the two arms are attached to the bowl edge. The bowl housing is rotatable with a tilt angle with respect to the arm tops. The light source is mounted inside the bowl housing for emitting a light from the light opening.

A luminaire is configured to be removably coupled to a fixture, the fixture being removably coupled to a splice box, the luminaire including a housing including a first end and a second end, the first end including a coupling mechanism configured to couple to the fixture; a printed circuit board coupled adjacent the second end; at least one LED physically and electrically coupled to the printed circuit board; a lens couple to the housing over the printed circuit board; an adapter in electrical communication with the printed circuit board, the adapter configured to electrically and physically couple to a socket of the fixture.

A downlight apparatus includes a heat dissipation unit, a light source, a driver module, a light guiding module, a light guiding unit and a protruding portion. The protruding portion has a top portion and an enlarging portion. The top portion is attached to the heat dissipation unit and has a smaller diameter than the enlarging portion.

A household lighting lamp and a control method for a household lighting lamp. The household lighting lamp comprises a lamp holder, a main light-emitting component, and a secondary light-emitting component; the front side of the lamp holder is a front panel, and the rear side of the lamp holder is a mounting part; the main light-emitting component is disposed in front of the lamp holder, the secondary light-emitting component is disposed behind and/or at the side of the lamp holder, and the main light-emitting component and secondary light-emitting component are electrically connected to a control circuit. The illumination of the lighting lamp can be conveniently adjusted, and the light sensation of the lamp is comfortable and can be adapted to requirements of a user in different scenarios.
