Abstract: A luminaire especially adapted for outdoor use wherein the cover member is pivotally connected to the housing to permit ready access to the luminaire's internal parts (e.g., lamp and ballast components). Located within the cover is a lens which is held in position by a compressible gasket. The gasket is compressed against an internally located mounting plate to provide a seal as well as assist in retaining the lens in position. The preferred light source is a high intensity discharge (HID) lamp (e.g., high pressure sodium).

Abstract: A luminaire having a boxlike housing with a removable cover secured thereto. The luminaire's reflector, having the socket and lamp components located therein, is rotatable on a planar mounting plate, thus enabling two light output distributions (patterns) to be provided, each at about ninety degrees from the other. The preferred lamp is a high intensity discharge (HID) lamp (e.g., high pressure sodium).

Abstract: A connecting device for securing a vertically suspended lighting fixture to the housing of an electrical junction (wiring) box in such a manner that the lighting fixture can be pivoted to an open position to enable interconnection of the fixture's and junction box's electrical wiring in a safe, facile manner. The device includes a safety means to prevent accidental removal (separation) of the fixture and junction box while in the pivoted, open position. In a preferred embodiment, the invention includes a pair of planar, substantially rectangular plate members. A first of these members is designed for being attached to the junction box and the second for being secured to the lighting fixture. Located on the second plate is a pair of upwardly projecting tab members adapted for being inserted within a corresponding pair of elongated openings located within the first plate member.

Abstract: A luminaire designed for outdoor applications (e.g., illuminating roadways and alleyways) and including an improved latching means in the form of two spaced-apart, depressible leaf springs, each including a cam surface for slidably engaging one of the sides of the luminaire's mounting plate during insertion thereof within the luminaire's housing to cause the biased spring to move to an open position (from its closed position) and thereafter clamp against the plate to effect positive retention thereof.

Abstract: A luminaire particularly suited for outdoor applications (e.g., for illuminating roadways and alleyways) and including a two-part housing wherein one of the parts (the base) is metallic and the other (refracting portion) is of lightweight (plastic) material and includes both an opaque chamber for housing the luminaire's lightweight rectangular aluminum reflector and a refracting, multiplanar prismatic lens. The reflector is slidably positioned in the chamber portion and thus readily removable when both parts of the housing are separated. The luminaire is capable of providing a predetermined scheme of light distributions (including IES types II, III, and IV) on the ground therebelow when oriented in either a horizontal or vertical position.

Abstract: A lighting fixture arrangement including a lighting fixture suspended from a supporting structure at a first height, and a hanger arrangement located remotely from the lighting fixture and attached to a supporting structure at a second, lower height. The lighting fixture includes a power supply assembly and an optical assembly suspended from the power supply assembly and adapted to receive operating voltages over a cable for operating the optical assembly to illuminate a first area or region beneath the fixture. In accordance with the invention the optical assembly is capable of being removed, or separated, from the rest of the fixture and carried together with its associated cable to the remote hanger arrangement and suspended from the hanger arrangement to illuminate a second area or region beneath the hanger arrangement. The hanger arrangement does not have, and does not require, a power supply assembly of its own, thereby reducing the required mounting space in the vertical dimension.

Abstract: A mounting arrangement for mounting a ballast transformer to a structural support member. As employed in accordance with the invention, the ballast transformer has an opening through the core portion thereof. A pair of L-shaped mounting members are mounted to the ballast transformer by means of a pair of elongated, compressible mounting pins, commonly known as "rollpins," which are driven through openings in the vertical portions of the L-shaped mounting members into opposite entrances of the opening in the ballast transformer. The mounting members are then secured to the structural support member by means of threaded fasteners which are inserted through openings in the structural support member and threaded into openings in the horizontal portions of the L-shaped mounting members. The threaded fasteners are selected to have lengths so that the threaded portions thereof will extend past the exposed ends of the mounting pins and be immediately adjacent thereto.
