DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
To present a better understanding of the invention, particular embodiments thereof will now be described and illustrated in the Figures. Reference to the Figures showing embodiments of the presently claimed invention are made simply to describe the presently claimed invention and not to limit the scope of the claims herein.
A traditional style post-top luminaire is provided having a design reducing maintenance costs. Optionally, the luminaire has a substantially isolated water and dust tight optical chamber and may incorporate a unique design of tool-less access to a re-lamping module and/or a removable electrical gear tray. Incorporating each of these options provides access to substantially all internal components through a hinged door on a bottom luminaire capital without the need for tools.
A sealed optical chamber is achieved by gasketing between the roof, globe, and bottom luminaire capital. Preferably, a dual radial sealed removable socket casting allows for tool-less removal of a lamp and relamping via access to a relamping module. The dual radial sealing method for a re-lamping module is preferably a submersible rated gasketing method. The relamping module has a relamping post extending upward from a base cooperating with a central portion of a radial sealed socket casting and has a lamp socket thereon. Electrical gear is preferably attached to a removable tray mounted in the capital which is removable and replaceable in a tool-less manner.
A user has access to the lamp for replacement and servicing of the electrical gear at the same time via an optional tool-less latch through a bottom capital. Thus, a post-top luminaire may have totally tool-less access and the capability to service most all of the components that require typical maintenance in a tool-less manner.
With reference to FIG. 1, luminaire 10 is illustrated in one position mounted at the top of a post 12. The external structure of the luminaire 10 is substantially symmetrical about a central vertical axis, and thus FIG. 1 illustrates the exterior of the luminaire 10 as perceptively viewed from substantially any side thereof. From an external perspective, luminaire 10 generally comprises a luminaire base 14 supporting a capital 16. Capital 16 has an opening in the top thereof wherein globe 18 is sealably retained forming an optical chamber within. Atop globe 18 is roof 20 which sealed to globe 18 forming an optical chamber substantially sealed off from the exterior environment. Roof 20 is optional as globe 18 could have a top without an opening therein. Preferably, globe 18 is an acorn globe.
With reference to FIGS. 2 and 3, luminaire 10 has capital 16 attached to base 14 with cast top 32 there between. Base 14 resides atop post 12. Capital 16 has door 22 open showing the internal components therein. Electrical assembly 24 is removably retained within capital 16 with retainer 37, being retained on door 22, providing easy access and removability. Door 22 is attached to capital 16 via hinge 26. Tab 29 is attached near an edge of door 22 and is oriented to cooperate with tool-less latch 28 on capital 16 providing tool-less access to electrical gear assembly 24, relamping module 40, and other internal components thereof. FIG. 2 shows relamping module 40 in a sealed position within capital 16 about dual radial sealed socket casting 39 with relamping module sealing base 30. Relamping module sealing base 30 seals about dual radial sealed socket casketing 39 with a twisting action or vertical placement thereon. Optionally, threads are about an outer portion of dual radial sealed socket casting 39 which cooperate with optional threads on an inner surface of relamping module sealing base 30.

FIG. 10A shows luminaire 1000 having an upper sectional cut-away detailed in FIG. 10B. Luminaire 1000 has capital 1072 attached to base 1071 for mounting atop a post. Capital 1072 has hingedly attached door 1081 open showing the internal components therein. Electrical assembly 1085 is removably retained on door 1081 with retainer 1037 providing easy access and removability. Electrical assembly 1085 has handle 1087 extending from an upper portion for tool-less removal. Tab 1029 is attached near an edge of door 1081 and is oriented to cooperate with tool-less latch 1028 on capital 1072 providing tool-less access to electrical gear assembly 1085, relamping module 1044, optional photo control 1075, terminal block 1076, and other components therein. FIG. 10B shows an enlarged view of the cut-away portion shown in FIG. 10A detailing the cooperation between capital 1072, dual radial sealing method having seals 1101, outer globe ring 1061, inner globe ring 1063, relamping module 1144, and globe 1064. Relamping module 1144 is shown in a sealed position within capital 1072 with a dual radial sealed socket casting, having dual radial seals 1101, section of inner globe ring 1063. Radial seals 1101 are optional as it is not required to have an air tight seal about relamping module 1144. Optionally, inner globe ring 1063 may have a single radial seal 1101. Relamping module sealing base 1030 has relamping post 1036 depending upward from a central portion and has an outer cylindrical section sealed about dual radial seals 1101. The sealing of relamping module 1144 within inner globe ring 1063 can be done with a twisting action or vertical placement of sealing relamping module base 1030 about dual radial seals 1101 environmentally sealing a lamp atop relamping post 1036 within a central portion of globe 1064. Optionally, threads are about an outer portion of the dual radial sealed socket casting section of inner globe ring 1063 which cooperate with optional threads on an inner surface of relamping module base 1030. Optional retaining bracket 1033 has a central portion engaged with relamping module base 1030 and slots in outwardly and upwardly depending flanges cooperating with retainers 1038 holding relamping module 1044 in a sealed position about dual radial seals 1101. Retainers 1038 threadingly engage and depend downwardly from outer globe ring 1061 having a head separated from outer globe ring 1061 a distance of at least the thickness of retaining bracket 1033 enabling rotating engagement of 1033 with retainers 1038. Also shown here is gasket 1012 cooperating with a lower edge of globe 1064 and located within a recess in inner globe ring 1063. The seal formed between globe 1064 and inner globe ring 1063 with gasket 1012 and the seal formed between relamping module 1144 and inner globe ring 1063 with radial seals 1101 provides tool-less access to a lamp mounted atop relamping post 1036 while providing an environmentally sealed globe 1064.
Relamping of embodiments of the post-top luminaire can be accomplished in a completely tool-less manner. For example, in this embodiment capital door 1081 is opened by releasing tab 1029 from latch 1028. Relamping module base 1030 is then released from a globe ring 1063 in a tool-less manner. In this embodiment base 1030 is rotated in a counter-clockwise direction releasing retaining bracket 1033 from retainers 1038. Relamping module 1144 is then lowered from globe 1064 exposing a lamp mounted atop relamping post 1036 allowing removal and replacement of the lamp. The lamp is then placed within the aperture in globe ring 1063 and relamping module 1144 is raised up into globe 1064 and base 1030 is secured to globe ring 1063 with a clockwise rotation. Capital door 1081 is then closed completing the relamping process.
