The present disclosure relates generally to artificial lighting fixtures, more specifically, wall pack light fixtures configured for mounting, protecting and supporting electrical connection with light elements contained in the wall pack light fixtures to at least one of a wall, a pole and support structure.
Artificial lighting has proven to be useful in a wide variety of locations and situations, including both indoors and outdoors. One form of useful lighting is known as a wall pack light fixture, or more simply, as a wall pack. A wall pack is also sometimes known as a luminaire enclosure. A wall pack light fixture may enclose one or more electrical lighting elements and associated electrical conductors while supporting the reception and use of electrical power by those lighting elements. Because wall pack light fixtures are generally intended for outdoor environments, although they may also be used in indoor environments, they tend include a housing designed to be more robust than typical indoor lighting fixtures. Typically, the housing provides some measure of protection against outdoor weather hazards such as fresh water, salt water, temperature extremes, sunlight, animals, dust, debris, and even occasionally, corrosive chemicals, combustible materials, explosive materials, etc., that could otherwise affect the operation of the lighting elements and the electrical conductors.
A wall pack light fixture is often designed for mounting on a pole, wall or other elevated structure in the outdoors environment. Some wall pack light fixtures include a mounting portion for mounting to the elevated structure and a cover portion for covering, at least in part, the lighting elements and electrical conductors to protect them from hazards in the outdoor environment. The mounting portion and the cover portion are physically coupled together.
While installation of a wall pack light fixture may occur in a variety of ways, often installation includes physically coupling the mounting portion to an elevated structure. In addition to physically coupling the mounting portion, electrical contacts in the wall pack lighting fixture are conductively coupled to external electrical wiring for providing electrical power to the lighting elements. Once a physical and electrical coupling is made, the cover portion is attached to the mounting portion.
Unfortunately, existing wall pack light fixtures have certain associated limitations and difficulties. For example, wall pack light fixtures light fixtures can be difficult to install, control and service after installation. It would also be desirable to eliminate or mitigate one or more of the limitations and difficulties associated with wall pack light fixtures.
In some embodiments, the present disclosure describes a wall pack light fixture including a hinge, the hinge having a first portion and a second portion rotatably coupled to the first portion, a front cover, the front cover connected to the first portion of the hinge, the front cover including a light engine, and a rear enclosure, the rear enclosure connected to the second portion of the hinge. A rear facing portion of the front cover acts as a front cover contact surface for receiving contact from the front facing edge of the rear enclosure. A seal is formed where the front cover contact surface engages the front facing edge of the rear enclosure. In preferred embodiments of the invention, the hinge is an offset hinge. As used herein, an offset hinge is a hinge that permits a closure of the front cover so that the front cover closes substantially perpendicularly against the rear enclosure as it is making closing contact. This permits uniform pressure between the rear enclosure and the front cover contact surface and can enhance the seal between the rear enclosure and the front cover contact surface. Preferred offset hinges offset the pivot point of the hinge from the plane of the contact surface to enhance uniform contacting pressure upon closing.
In some other embodiments, the present disclosure describes a wall pack light fixture including a hinge, the hinge having a first portion and a second portion rotatably coupled to the first portion, a front cover, the front cover connected to the first portion of the hinge, the front cover including a light engine, and a rear enclosure, the rear enclosure connected to the second portion of the hinge, the rear enclosure including an occupancy sensor.
In some still other embodiments, the present disclosure describes a wall pack light fixture including a hinge, the hinge having a first portion and a second portion rotatably coupled to the first portion, a front cover, the front cover connected to the first portion of the hinge, the front cover including a light engine, wherein the light engine includes at least one of a light emitting diode (LED), a halogen light and an incandescent light, and a rear enclosure, the rear enclosure connected to the second portion of the hinge, the rear enclosure including an occupancy sensor and a battery backup, wherein the battery backup is electrically connected to the light engine and configured to provide electrical energy to the light engine in response to detection of an occupant by the occupancy sensor.
The figures depict embodiments for purposes of illustration only. One skilled in the art will readily recognize from the following description that alternative embodiments of the structures illustrated herein may be employed without departing from the principles described herein, wherein:
The following description and drawings are illustrative and are not to be construed as limiting. Numerous specific details are described to provide a thorough understanding of the disclosure. However, in certain instances, well known or conventional details are not described in order to avoid obscuring the description.
Reference in this specification to “one embodiment,” “an embodiment” or the like means that a particular feature, structure, characteristic, advantage or benefit described in connection with the embodiment may be included in at least one embodiment of the disclosure, but may not be exhibited by other embodiments. The appearances of the phrase “in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Similarly, various requirements are described which may be requirements for some embodiments but not for other embodiments. The specification and drawings are to be regarded in an illustrative sense rather than a restrictive sense. Various modifications may be made thereto without departing from the spirit and scope as set forth in the claims.
The present disclosure describes wall pack light fixtures eliminating or mitigating one or more of the limitations and difficulties associated with other wall pack light fixtures. As described herein, some embodiments include a rear contact surface and a front cover connected by a hinge to a rear enclosure to make installation and servicing easier. When closed, the front cover contacts the rear contact surface and seals the components within the wall pack light fixture from the elements. The hinge is configured in such a way as to permit the wall pack light fixture to remain open, exposing the inside portions, to avoid having to hold the wall pack light fixture open in some situations. This feature simplifies installation and servicing, for example, by freeing a hand of an installer or servicer, thereby enabling safer and more effective installation and service. In preferred embodiments of the invention, the hinge is an offset hinge and, in any event, is configured to permit the front cover to press uniformly and close perpendicularly with uniform pressure against the rear contact surface. Furthermore, as described herein, some embodiments include an occupancy sensor adapted to control the wall pack light fixture to provide light when an area is occupied. This feature provides better control to provide light when it deemed useful and saving power when light is deemed not necessary. Still further, as described herein, some embodiments include a battery backup adapted to power the wall pack light fixture to provide light. In some embodiments, this feature provides power for lighting in lieu of a primary electrical power source, such as when primary power is lost.
