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 overhead light fixture includes a driver assembly and a light-emitting assembly. The driver assembly includes a driver and a housing. The light-emitting assembly is operably connected to the driver and configured for downward emission of light from a light source of the light-emitting assembly. The light-emitting assembly is detachably secured to the driver assembly. The light fixture is configured to be mounted to a canopy sheet of an overhead canopy, with the driver assembly disposed above the canopy sheet and the light-emitting assembly disposed below the canopy sheet. The driver assembly is optionally configured so that, when the light-emitting assembly is detached from the driver assembly, the driver is removable downwardly through the base portion. A bezel is optionally disposed around a lens of the light-emitting assembly, for aesthetic reasons and/or for controlling a degree of lateral emission of light from the light fixture.

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 fixture configuration module comprises a connector configured to be removably coupled with a light fixture. The fixture configuration module also comprises fixture control circuitry communicatively coupled to the connector and configured to control the light fixture to produce light in accordance with a range of a lighting parameter. The range includes at least a subset of values supported by the light fixture for producing light. The fixture configuration module further comprises range control circuitry communicatively coupled to the fixture control circuitry and configured to wirelessly receive the range at least while the connector is uncoupled from the light fixture, and designate the range to the fixture control circuitry while the connector is coupled to the light fixture.

A lighting fixture includes a light engine, a reflector, a housing, and an adjustment assembly for moving the reflector relative to the housing. The light engine includes a light emitter. The reflector is positioned proximate the light emitter and is configured to receive light output from the light emitter. The housing is positioned around at least a portion of the reflector. The adjustment assembly includes a first adjuster and a second adjuster.

A multifunction lighting apparatus includes a light body, an adjustment bracket, and a frame. More than one optical unit may be selected to be installed to the multifunction lighting apparatus. In addition, the light body may be moved with respect to the adjustment bracket to provide more flexible light effect.

An integrated ceiling device includes a housing retaining an electronic assembly, a heat sink having a central opening, a light source coupled onto the heat sink, the housing is coupled with and disposed at least partly above the heat sink, and a central vertical axis of the housing aligns or is in proximity with the central opening of the heat sink.

An illumination device includes a plurality of light-emitting elements (LEEs); a light guide extending in a forward direction from a first end to a second end to receive at the first end light emitted by the LEEs and to guide the received light to the second end; an optical extractor optically coupled to the second end to receive the guided light, the optical extractor including a redirecting surface to reflect a first portion of the guided light, the reflected light being output by the optical extractor in a backward angular range, and the redirecting surface having one or more transmissive portions to transmit a second portion of the guided light in the forward direction; and one or more optical elements optically coupled to the transmissive portions, the optical elements to modify the light transmitted through the transmissive portions and to output the modified light in a forward angular range.

A jewelry lighting lamp has a lighting part, a rotating part and a mounting part, the mounting part has a lamp barrel which accommodates the lighting part and rotating part. The rotating part has a driving motor, which drives the lighting part to rotate along the central axis of the lamp barrel; the lighting part has a main light source arranged on the central axis and one or more secondary light sources arranged around the main light source, the main light source and the secondary light source are driven by the rotating part to rotate along the central axis circumferentially. A jewelry lighting method using the jewelry lighting lamp is also provided. By varying luminance, the lamp solves the problem of visible light and shadows at the edge of the aperture when there are main and auxiliary light sources with different luminance.

A lighting apparatus includes a light source module, an internal housing, an exterior housing and a sliding track. The light source module including a LED module. The LED module may include multiple types of LED chips of different parameters that may be controlled to mix a desired parameter. The internal housing has a light opening and a protruding block. The light source module is fixed to the internal housing and a light of the LED module passes through the light opening. An exterior housing having a sliding groove. The exterior housing encloses the internal housing and allows the protruding block of the internal housing moving along the sliding groove to change a tilt angle of the light with respect to the exterior housing. The sliding track is used for the exterior housing to move along the sliding track for further adjusting an output direction of the light.
