A micro porous gas breather/filter assembly can be coupled to a housing of an electrical enclosure. The filter assembly has a two portion housing with the filter disposed between them. An adhesive on the filter attaches the filter to one or both portions of the housing. The filter allows gas to pass from the enclosure through the filter and to the atmosphere, but prohibits liquid from passing into the enclosure device. By filtering gases and liquids in this manner, the filter vents explosive and/or flammable gases from an electrical enclosure, while preventing liquid and other contaminants from entering the enclosure and damaging the electrical device or its wiring.

A recessed downlight for installation between joists located in a ceiling, comprising a socket box assembly and a hanger bar assembly that both adjust to the size of the space between the joists and various obstacles therein. The socket box assembly includes a housing having a socket enclosed therein providing an electrical connection for a lamp. The socket box housing is slidably coupled to the hanger bar assembly, thereby allowing the housing to be moved to a desired location along the length of the hanger bar assembly. Hanger bar assembly includes telescoping hanger bars and adjustable vertical legs. In addition, the vertical legs rotate with respect to the hanger bars, thereby allowing the installer to mount the downlight diagonally between joists. A trim and a can for the downlight are releasably attached to the socket box assembly without the use of tools, thereby allowing the installer to easily remove and/or replace the trim or can.

A lighting fixture assembly includes a lighting fixture having a mounting member, a pair of end plates, an elongated lamp and an elongated lens, and a pair of dust covers fittable over opposite ends of the lighting fixture. Each end plate is mounted to one of the opposite end of the mounting member and is substantially comprised of a first material having a first coefficient of thermal expansion. The lamp is mounted adjacent to the mounting member and extends between the end plates and has opposite ends disposed adjacent to the end plates. The lens is mounted adjacent to the mounting member and extends between the end plates and has opposite ends disposed adjacent to the end plates. The lens together with the mounting member and end plates substantially encloses the lamp. The lens is substantially comprised of a second material having a second coefficient of thermal expansion different from the first coefficient of thermal expansion of the first material of the end plates such that when the lens and end plates are heated during illumination of the lamp a difference in expansion of the second material of the lens and the first material of the end plates occurs creating gaps between the opposite ends of the lens and end plates. Each dust cover securably fits over one of the end plates, one of the opposite ends of the mounting member and one of the opposite ends of the lens for covering the gaps therebetween and thereby sealing the assembly at the locations of the gaps to prevent foreign matter from entering the assembly through the gaps.

A lighting fixture with emergency illuminating device having a housing, first and second electrical sockets, first and second lamps, and a first translucent cover. The housing having electrical wiring for connection to a power source. The first electrical socket coupled to the housing and electrically coupled to the wiring, and having a first central axis and a first width transverse to the first central axis. The second electrical socket coupled to the housing and electrically coupled to the wiring, and having a second central axis and a second width transverse to the second central axis that is greater than the first width of the first electrical socket. The first lamp having a connecting end removably coupled within the first electrical socket and a translucent bulb portion extending from the connecting end. The second lamp having a connecting end removably coupled within the second electrical socket and a translucent bulb portion extending from the connecting end of the second lamp. The first lamp located within the first cover and the second lamp located outside the first cover.

Lighting fixture with emergency illuminating device

An emergency lighting fixture with backup battery power for illuminating aimable lamps or a plurality of lamps mounted in a single housing in response to loss of power. In the preferred embodiment, the lighting fixture has three independently adjustable lamps mounted within a single housing. The lamps are adjustable about vertical and horizontal axes for maximum aiming capabilities. The housing is preferably an explosion proof housing with a glass globe for mounting in hazardous locations or areas. The glass globe allows the lamps to be aimed through 360.degree. so that light transmitted by the lamps can be aimed to a specific area adjacent the lighting fixture. The lighting fixture also preferably has its backup batteries mounted within the housing along with a charger for maintaining the batteries at full charge.
