A light fixture can include a housing comprising at least one wall that forms a cavity, wherein the housing complies with applicable standards for a hazardous environment. The light fixture can also include an antenna assembly disposed on an outer surface of the housing. The antenna assembly can provide communication with another device within the hazardous environment without compromising the applicable standards for the hazardous environment.

An LED light bulb with integrated power supply, and which may incorporate integrated communications and processing functions. The LED light bulb is designed to be efficiently manufactured in mass quantities using automated assembly techniques, and is constructed to exhibit the spatial light pattern of a regular incandescent bulb as closely as possible. Where communications and processing functions are integrated, the LED light bulb is able to communicate via wireless communications to a mobile phone, notebook, tablet, or other computing device.

A waveguide body comprises a length from a first end to a second end along a longitudinal axis, and a coupling portion that comprises first and second coupling surfaces. The first and second coupling surfaces define, at least in part, an elongate coupling cavity along the entire length of the waveguide body and a surface located opposite the coupling cavity. The waveguide body further comprises first and second opposed sections extending along the length of the waveguide body. The first and second opposed sections further comprise respective first and second lower surfaces disposed at different first and second side section angles with respect to a first axis lying in a plane normal to the longitudinal axis. The first axis bisects the coupling portion. Among other things, such a waveguide may be included in a luminaire along with a light source.

The present disclosure discloses a lighting apparatus and relates to a lighting field. The lighting apparatus includes an outer housing, an inner housing, a face ring, a functional module and a first conductive wire. A portion of the inner housing is arranged inside an accommodating cavity and separates the accommodating cavity of the housing into a light source cavity and a via cavity; the face ring is located outside the accommodating cavity and connected with the inner housing, and encloses to form an installation cavity; the installation cavity is sequentially in communication with the via cavity and the first via hole, so that the functional module mounted in the installation cavity may be electrically connected with the first conductive wire; and the first conductive wire sequentially passes through the via cavity and the first via hole to extend out of the housing.

An improved magnetic induction lighting fixture for wide area lighting and other uses is disclosed. The magnetic lighting fixture of the present invention provides a tubular magnetic induction lamp in a lighting fixture which provides maximum light dispersion from the fixture, wherein the light dispersion and focal distance are adjustable depending on the application. Specially, the lighting fixture integrates an assembly containing the tubular magnetic induction bulb into a housing unit having a primary reflector element at the center of the housing that is specifically configured for the geometry of the magnetic induction bulb. The internal surface of the housing constitutes a secondary reflector, providing a high-efficiency reflection surface which, together with the primary reflector, provides for maximum reflection and focus of the light produced by the magnetic induction bulb. The lighting fixture further incorporates a mechanism for raising or lowering the magnetic bulb assembly within the fixture in proportion to the primary reflector element and the secondary reflector surface, providing the capability of varying or adjusting the focal length of the fixture light beam as well as disbursing the light in varying patterns.

A lighting fixture includes a first housing portion and a second housing portion. The first housing portion includes a base and a wall extending outwardly from substantially the perimeter of the base. A top portion of the wall includes one or more hinges extending outwardly therefrom. The second housing portion includes a front panel and a side panel extending outwardly from substantially the perimeter of the front panel. A top portion of the front panel includes at least one slot. The second housing is coupled to the first housing in an open position when the hinge is inserted into the slot and the front panel is disposed elevationally above the base. The second housing is coupled to the first housing in an operational position when the hinge is inserted into the slot and the front panel covers the base.

This application discusses components that can be used to prevent flame or hot gas transmission from the inside of a luminaire enclosure to the outside of a luminaire enclosure due to an internal explosion, thereby yielding an explosion encapsulating luminaire enclosure. Accordingly, the components and assemblies described herein can be safely integrated with systems that operate in the presence explosive gas.
