A high-intensity discharge lighting fixture of the type having an optics housing and optics components mounted therein, the fixture comprises a ballast housing having a first member and a second member including at least one airflow channel integrally formed therein, the airflow channel is positioned immediately adjacent the optics housing and is adapted to facilitate free airflow between the ballast housing and the optics housing whereby heat is dissipated from the lighting fixture to the atmosphere.

The improved bollard luminaire has an upwardly directed, elliptical main reflector and a lamp 'nested' within such reflector and positioned at or near its lower focal point. An upper cone-shaped reflector receives light from the main reflector and directs it laterally through a transparent lens element. Such element provides a 360&#xb0; lateral light opening unobstructed by wiring, support posts or the like. Light reflected through such opening is relatively sharply focused along an axis about 70&#xb0; from vertical. Unreflected light from the lamp which 'misses' both reflectors also provides a degree of &#x201c;uplighting,&#x201d; often found useful for aesthetic purposes.

Bollard luminaire

Luminaires for illuminating a target zone having target zone subregions in front of and to the sides of the luminaire. The luminaire includes a housing, a lamp holder in the housing positioned to support an electric lamp in a generally vertical orientation, and a compound parabolic reflector in the housing partially surrounding a lamp light-emitting segment location having plural regions. Preferred forms of the compound parabolic reflector include segmented center and side portions. The preferred segmented center portion has a first plurality of two-dimensional parabolic segments each of which has a focal point in a different one of the plural light-emitting segment location regions. The preferred segmented side portions are each provided with a second plurality of two-dimensional parabolic segments having focal points along the light-emitting segment location. The parabolic segments are effective to direct a preponderance of light toward the plural target zone subregions.

A hinging mechanism attaching an access panel to a housing is provided that has a latching device rigidly mounted to the inner surface of the panel and releasably pivotally secured to the interior surface of the housing, whereby the panel is detachable from the housing and free to move between open and closed positions. Preferably, the mechanism further includes a linkage member movably mounted to the interior surface, whereby the mechanism has articulation at independent points between the housing and the panel. The mechanism is also preferably one where the latching device includes a latch-bracket and a latch, the latch being pivotally attached to the latch-bracket.

An apparatus for mounting a lighting fixture is provided having a mount housing with at least one pivot portion and a support panel with at least one hook portion, the support panel being attached to the mount housing in a manner where the hook portion can slide and pivot with respect to the pivot portion. The pivot portion includes a rail, a tab-slot and a tab-rest, the tab-slot and tab-rest being adjacent to the rail and the hook portion has a hook member and a tab-stand adjacent to the hook member. The support panel is free to move between an open and a closed position and, preferably, detachable from the mount housing. A method for mounting a lighting fixture is also disclosed.

A light fixture having first and second housing members movable between closed-fixture and open-fixture positions for lamp-changing purposes, in which a first reflector member is secured to the first housing member and includes a first connection-edge, a separate second reflector member is separately secured to the second housing member and includes a second connection-edge abutting the first connection-edge when the housing members are in closed-fixture position, and a lamp-opening is between the first and second connection-edges, such that, when the housing members are in closed-fixture position, the reflector members together form a composite reflector in the fixture housing.

In an overhead industrial light fixture of the type including a housing with a base member and a top member forming a space, the base member forming a socket-receiving recess, and power-related components in the space, portions of the housing form a vertical airflow thermal chimney immediately adjacent to the recess and extending through the housing from bottom to top, to facilitate heat transfer to the chimney and heat-dissipating airflow to the atmosphere. The base member and top member are preferably formed of die-cast metal. A variety of preferred features are disclosed.

An industrial light fixture of the type including a housing with a base member and a top member and containing power-related components includes a spring-bracket secured to bracket-securement point(s), extending along the capacitor to hold the capacitor in place and biasing the capacitor into heat-exchange engagement against one surface of the top member to facilitate heat transfer from the capacitor to the top member and dissipation therefrom to the atmosphere. The base member and top member are preferably formed of die-cast metal and a variety of preferred features are disclosed.

An industrial light fixture of the type including a housing with a base member and a top member and containing power-related components includes spring-spacer apparatus between the base member and the ballast, such that, with the top member closed with respect to the base member, the spring-spacer apparatus biases the ballast into heat-exchange engagement with at least one surface of the top member and provides an air gap between the ballast and the base member. The base member and top member are preferably formed of die-cast metal and a variety of preferred features are disclosed.
