Abstract

The pendent style luminaire split design incorporates generally a housing split into sections, a first section of the housing is attached to the top member located at the mounting arm while the second section of the housing is attached to the lens frame. The second section swings about a hinge between the first section and the lens frame. In the open position of the luminaire, the design allows for the convenience of "hands free" maintenance of both the lamp and the electrical component assembly of the luminaire at the same time. A sealed optical chamber is created, since neither the lens nor lens frame is needed to be separated from the reflector to gain access to the lamp.

DETAILED DESCRIPTION

100091 The pendent style luminaire 20 of the present invention depicted in the drawings functions to create convenience for "hands free" maintenance of both lamps and electrical component assemblies or other internal components at the same time.
The luminaire 20 design also provides dust and water tight seals to prolong the life and minimize maintenance of the lamp and luminaire.

[0010] With reference to FIGS. 1 and 2, a pendent style luminaire 20 may include a top casting 50, a housing 22, a lens frame 60, a reflector 72, and a lens 70.
Housing 22 may be further divided into a first housing 42 and a second housing 32. Luminaire 20 is capable of being opened for access by a user whereby a hinged bottom 30, comprising a second housing 32, lens frame 60, a reflector 72, and lens 70, is hingedly attached to first housing 42 of hinged top 40. Luminaire 20 may be rotated by means of hinge 49 from a closed configuration, as shown in FIG. 1, to an open configuration, as shown in FIG.
2.

GL-SPL2!CDA 2 [0011] As shown in FIGS. 1, 2, 3, and 4, housing 22 comprises a flared first housing 42 and a similarly flared second housing 32 mutually opposed and substantially parallel. A
top member or casting 50 is disposed orthogonally to the first housing and second housing, and lens frame 60 is disposed orthogonally to the lower portion of the first housing and second housing. Lens 70 is disposed over an open aperture 66 formed by lens frame 60.
Housing 22, top casting 50, and lens frame 60 may be made from, but not limited to, cast aluminum or other materials known in the art for example metal or plastic.
Housing 22 is essentially split along a substantially vertical axis separating first housing 42 and second housing 32 from each other. Although the housing 22 is shown in great detail with a substantially vertical split, it should be understood that there are many variations of the shape of the line of demarcation between hinged top 40 and hinged bottom 30 that can be used within the scope of the invention.

[0012] Lens frame 60 as shown in FIGS. 2, 3, and 4 is hingedly attached to first housing 42 to allow for luminaire 20 to rotate from a closed configuration (FIG. 1) to an open configuration (FIG. 2). Lens frame 60 is substantially ring-shape, and essentially half the circumference of lens frame 60 is secured to a bottom end 33 of second housing 32. The remaining half of the circumference of lens frame 60 may be releasably secured to a bottom end 43 of first housing 42. A hinge 49, hingedly connecting lens frame 60 to bottom end 43 of first housing 42, is located in a substantially opposed position from the area where second housing 32 is secured to lens frame 60. Because hinge 49 is placed in a substantially opposed position, the weight of second housing 32 maximizes the cantilever action that occurs when the luminaire naturally travels to its open configuration (FIG. 2) by gravity.
The cantilever action pivots about hinge 49 which may allow lens 70, lens frame 60, reflector 72, and second housing 32 (hinged bottom 30) to travel to its open configuration and remain in the open configuration without requiring the user to tie up his or her hands to keep luminaire 20 open for access by the user. The natural cantilever action of hinged bottom 30 provided by gravity, allows for internal component access without requiring the luminaire to be kept open by hand.

[0013] Hinge 49, illustrated in FIGS. 2, 3, and 4, is merely representative of hinges in general, and it should be understood that there are many locations and variations of hinges that may be used with hinged top 40 and hinged bottom 30 sections. For example, a hinge 'may be placed externally to housing 22 (not shown) and still function to swing hinged bottom 30 into an open configuration.

[0014] As shown in FIGS. 1-4, top casting 50 is generally dome-shaped with housing 22 depending therefrom. As shown in FIG.1, top casting 50 may be secured to a mounting arm 100, or other mounting device known in the art, which in turnmay extend from a pole assembly (not shown). Top end 44 of first housing 42 is affixed to generally half of a lower end 54 of the top casting, while the remaining portion of lower end 54 of the top casting is releasably affixed to a top end 34 of second housing 32. In the closed configuration (FIG. 1), top casting 50 may have a manually operated latch 52 which engages second housing 32 to enable the second housing to be releasably secured. However, there are a variety of mechanisms known in the art, with manually or tool operated, which can be used to secure Iuminaire 20 in the closed configuration and still be within the scope of the invention. First housing 42 also has two opposed edges 45 and 46 which engage respectively with second housing's two opposed edges 35 and 36. The mating of the respective edges along the line of demarcation between the hinged bottom 30 and hinged top 40 may include gaskets, o-rings, seals or the like to provide sealing along the line of demarcation, resulting in longer life of the lamp and minimizing maintenance of internal components such as a electrical component assembly 90. Also, the mating of hinged bottom 30 and hinged top 40 along the line of demarcation may incorporate tongue and groove mating to maximize the sealing engagement when closing the luminaire into the closed configuration.

100151 As shown in FIGS. 1-5, lens 70 or globe depends from or seats within lens frame 60. Lens 70 may be substantially, but is not limited to, acorn shaped.
The globe or lens 70 is typically made from glass or plastic. The ring-shaped lens frame 60 allows for lens 70 to pass through open aperture 66 of the lens frame and rest within the interior surface of the lens frame. Located adjacent to lens 70 is reflector 72 of luminaire 20.
Reflector 72 extends from the junction between lens 70 and lens frame 60 in the opposite direction from lens 70. Reflector 72 has an open aperture 73 (FIG. 6) being dimensioned to receive a lamp module 80 and to focus light generated from a lamp 82 towards lens 70. A seal 64 creates a sealing mechanism at the junction between reflector 72, lens 70, and lens frame 60. Sea164 with its engagement with lens 70 and reflector 72 may be held in place by a lens frame clamp 62 as shown in FIG. 5. Although sea164 is shown in detail, the junction between the lens frame, lens, and reflector may include a gasket, o-ring, or any seal or combination thereof known in the art to create the required sealing effect. Seal 64, enclosing the optical chamber of the lens, lens frame, and reflector, is essentially permanent because the sea164 remains unbroken since neither lens, lens frame, nor reflector need to be separated to gain access to lamp module 80 for repair, replacement, or maintenance. This essentially sealed optical chamber creates a water and dust proof enclosure which prolongs the life and minimizes the maintenance required of the lamp and luminaire.

[0016] During maintenance, lamp module 80 is accessible by the user when luminaire 20 is positioned in the open configuration (FIG. 2). Open aperture 73 of reflector 72 may have a dual radial-sealed, removable socket casting 74 allowing for the tool free removal of lamp module 80 for re-lamping. Lamp module 80 has at its base 84 an inner circumferential surface which may seal to a single or dual radial-sealed socket casting 74.
The dual seal may be created by an upper o-ring 75 and a lower o-ring 76. Dual radial-sealed socket casting 74 is affixed to or part of aperture 73 of reflector 72. Lamp module 80 may also have an internal thread to cooperate with external threads on the dual radial sealed socket casting. Lamp module 80 may be installed by axially inserting the module into reflector 72 and turning to lock and seal the top of the optical chamber. With lamp module 80 capable of being removed without the aid of tools, the lamp module is conveniently replaced. Although the seal engagement between lamp module 80 and socket casting 74 is shown in detail, a variety of seals or gaskets about the lamp module could be used to create and maintain the water and dust proof enclosure of the optical chamber.

[0017] Although lens 70, lens frame, 60, and reflector 72 are shown in detail in FIGS. 2, 5, and 6, they are merely representative of lens, lens frames, and reflectors in general, and it is to be understood that there are many variations of those components that may be used with the luminaire. For example as shown in FIG. 7, a lens 170 affixed in luminaire 120 is substantially flat in shape while a reflector 172 has a low profile extending in a direction away from lens 170. Luminaire 120 has a hinged bottom 130 hingedly connected to a hinged top 142 by hinge 149. Also, as shown in FIG. 7, a lamp module 180 may extend horizontally from a lateral aperture in the reflector.

100181 In use, pendent style luminaire 20 is operably connected to a power source (not shown). As shown in FIGS. 2, 3, and 4, lamp module 80 may be operably connected by a wire connection 92 to an electronic component assembly 90 located on the interior surface of first housing 42. Electronic component assembly 90 may then be wired through an open orifice 56 in top casting 50 and through mounting arm 100 (FIG. 1), or any other appropriate mount, to an external power supply (not shown). Electronic component assembly 90 may be mounted directly onto the interior of first housing 42 or may be attached to a removable tray inside the housing. Electronic component assembly 90 may include of a ballast, a capacitor, and an ignitor. As shown in FIG. 3, the removable electronic component assembly 90 may be mounted within first housing 42 at the bottom end 94 of the assembly which is secured by a clip 48 affixed to the interior surface of first housing 42. Clip 48 releases assembly 90 from engagement with the inner surface of first housing 42 for removal. Clip 48 may be manually operable without tools for quick removal. Electronic component assembly 90 may alternatively be attached inside the housing 22 in any number of locations by a variety of attachments known in the art including but not limited to screws or other manual or tool operated means. The convenience of manual removal without tools and the accessibility of the electronic component assembly optimizes the efficiency and ease of repair and maintenance by the user.

(0019) The luminaire 20 design allows for the user to conveniently have their hands free for maintenance of both lamp module 80 and electrical component assembly 90 at the same time. Luminaire 20 may be opened from the closed configuration (FIG. 1) to the open configuration (FIG. 2) by a manual latch 52 joining top casting 50 to second housing 32.
Releasing latch 52 allows for hinged bottom 30 to pivot about hinge 49 in order for luminaire 20 to travel or cantilever to its open configuration. In traveling to the open configuration (FIG. 2), the weight of lens 70, lens frame 60, and second housing 32 results in a cantilever effect which minimizes the force needed by the user to open the luminaire. The weight of hinged bottom 30 also allows for the luminaire to hang and remain in its open configuration.
Luminaire 20 remains in its open configuration without the aid of the user, thus the user needing to conduct maintenance on lamp module 80 and electrical component assembly 90 without needing to use their hands to keep the luminaire open and accessible.
This frees the user's hands for maintenance , both for re-lamping purposes and accessing the electrical component assembly 90 at the same time thereby allowing ready service to all the internal components that typically require maintenance.

[0020] There are many useful variations in size and shape of pendent style luminaire 20 that can be manufactured using this design. Although the housing 22, lens frame 60, top casting 50, lens 70, and reflector 72 are shown in one configuration in FIG.
1, that is merely one representation of various design configurations that can be used to allow "hands free"
access to both the lamp and electrical component assembly while also retaining a substantially permanent sea164 of the optical chamber. A plurality of aesthetic designs for the outer enclosure of the luminaire 20 can be created and still be within the scope of the present invention.

[0021] It is understood that while certain embodiments of the invention have been illustrated and described, it is not limited thereto except insofar as such limitations are included in the following claims and allowable functional equivalents thereof.
