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.
[0016] 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.
[0017] 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.
[0018] 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.

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

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.
[0026] Relamping of embodiments of the post-top luminaire can be accomplished
in a
CA 02685762 2009-11-12
8
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.
[0027] Alternative structure for the relamping module 530 is depicted in FIGS.
11-14. In
the variations shown, larger lamp types which are electrically connected to
the lamp
socket 538 may be accommodated and relamped without removal of the globe 18.
As
shown in FIG. 11, the lamp socket 538 has an electrical power cord 519
depending
through the cup 527 and may be directly affixed to socket connection wiring
which
extend below the cup 527 and which are directly connectable to the replacement
ballast
which may be supported on the door 22 of the capital 16. These electrical
connections are
not shown for ease of simplicity. Lamp socket 538 may retain the larger lamp
types
which may be removed downward through the capital 16 as shown in FIG. 14
through the
use of a hinge or pivot pin 537. Such hinge or pivot pin 537 allows the
relamping stem or
relamping post to flex relative to the cup 527 so that the relamping module
may be
removed from the fixture through the opening in the capital 16 covered by the
door 22.
[0028] Turning to the structure of the pivoting relamping module 530 shown in
the
figures, in the present embodiment the relamping post or stem may be comprised
of an
upper relamping post 536 which is hingedly or pivotally connected to a lower
relamping
post 531 or other structure from cup 527. As depicted, the upper relamping
post 536 has a
pivot pin 537 extending there through and through the lower relamping post
531. Upper
relamping post 536 may also have an arcuate face 534 which has an arcuate face
slot 535.
Arcuate face slot 535 may receive a slide 529 therein in order to lock the
upper relamping
post 536 in vertical position relative to the cup 527. Relamping module 530
may have
CA 02685762 2009-11-12
9
various structures supporting the lamp socket 538 and lamp 539 which may vary
from the
posts 536 and 531. A single stem may be provided extending directly upwards
from the
cup or other supporting structure to adequately support and position the lamp
539 in the
light chamber and which may be pivotally attached thereto.
[0029] A locking mechanism or slide 529 is shown allowing the upper relamping
post
536 to be locked in the vertical position. The slide 529 may be a dual
position slide, the
first position being a locked position wherein the upper relamping post 536 is
locked and
retained in the vertical position depicted in FIG. 11. The second position may
be in the
unlocked position wherein the slide 529 is pulled outwardly in the direction
of the arrow
of FIG. 11 towards the edge of or cup sidewall thereby aligning the slide
notches 528
with the arcuate face slot 535 thereby allowing the arcuate face 534 to rotate
within the
slide notch 528 and allowing the upper relamping post to hinge or flex
relative to the cup
527. Cup sidewall 526 will allow the slide 529 to extend shown in FIG. 11 to
be placed in
a second position to allow pivoting of the upper relamping post 536 relative
to the cup
527. Many different structures or embodiments for a locking mechanism may be
utilized
and implemented in the use of the cup 527 and the relamping stem or relamping
post 536.
In the various embodiments depicted, a lower relamping post 531 is utilized in
combination with the slide 529. However, various structures may be implemented
to lock
the upper relamping post in vertical position as disclosed.
[0030] As a benefit to the design depicted in the figures, slide 529 must be
in the locked
first position depicted in FIG. 11 in order for the cup 527 to be properly
installed on the
globe ring 1063 since when in the second position, slide 529 has a handle
portion which
extends outside the periphery of the cup side wall notch 526 thereby
preventing the cup
527 from being affixed to the globe ring 1063. The second position of the
slide 529
therefore allows the lamp to be pivoted relative to the cup but also prevents
the cup from
being installed unless it is adequately locked in such vertical position.
[0031] As shown in FIG. 12, the slide 529 is placed in the second unlocked
position
allowing the upper relamping post 536 to be pivoted relative to the cup 527,
thereby
CA 02685762 2009-11-12
causing the slide 529 to extend outward beyond the cup sidewall but allowing
the upper
relamping post 536 to flex and tilting the socket cup 538 such that the entire
relamping
module may be pulled out of the fixture and through the aperture in the
capital covered
by the door 22. Thus, even large lamp types may be removed from the fixture
without
removal of the globe.
[0032] As shown in FIG. 13, the socket cup 527 may be removed from the globe
ring
through a counterclockwise rotation allowing the spring clips 521 to become
disengaged
from formed bosses on the globe ring thereby allowing the cup 527 to be
removed
therefrom. Various wiring connections, which are not shown in the figures for
simplicity,
may be disengaged between the lamp and lamp socket 538 and the ballast
electronics
which may be hung on the door 22 and easily connectable to the lamp. Plug 523,
shown
in FIG. 14 may be implemented on a lower side of the cup 527 in order to allow
wiring
between the socket, lamp, plug 523, control electronics and ballast components
positioned in the capital interior or hung on the door 22. Inner globe ring
1063 shown in
FIG. 14, works in conjunction with the globe ring 1061 in order to receive the
cup 527
and the bosses formed thereof for engagement with spring clips 521. As can be
readily
understood, removal of the cup 527 from the inner globe ring 1063 may be
accomplished
through the disconnection of the cup 527 through rotation relative to the
globe ring,
downward removal of the cup 527 from the globe ring and positioning of the
slide 529
into the secondary unlocked position thereby allowing rotation of the upper
relamping
post 536 relative to the cup 527 as shown in FIG. 14. Once in such flexed
position, the
lamp 539 and relamping module 530 may be fully removed through the opening in
the
capital even when larger lamps are implemented. Also as indicated, when
reinstalling the
relamping module 530 relative to the globe ring, positioning of the slide 529
in order to
lock the upper relamping post 536 in vertical position relative to the cup 527
may be
accomplished. Such locking of the slide 529 into the first position and
preventing
pivoting or rotation of the relamping module prior to installation is
desirable such that the
lamp 539 is properly positioned within the globe upon installation of the cup
527 to the
globe ring. This may be accomplished after insertion of the lamp into the
aperture of the
globe ring, as shown in FIG. 14, and prior to locking of the cup on the globe
ring boss.

[0033] Various installation structure may be utilized for combinations with
globe ring
1061 and inner globe ring 1063. Such combinations include composite globe
rings, inner
globe rings, capital and globe ring interface structure all integrated into
single unitary
units and other known structures which make ease of installation and
manufacturing
accomplishable. The various structures depicted interfacing both the inner
globe ring
1063 and globe ring 1061 are exemplary only as various globe ring structures
may be
used which allow for an aperture to be formed entering between the capital 16
and the
globe 18 while allowing the removal of cup 527 and installation of the cup 527
to an
interior portion of the capital thereby properly positioning the lamp 539
within the globe.
In the present embodiment, the cup 527 is positioned below the inner globe
ring 1063 and
substantially covering the aperture formed in the globe ring combination. As
mentioned
however, various structures may be utilized to implement globe ring and globe
structure
inter-face in combination with the capital 16.
[0034] Capital 16, as previously described, will also have the capital access
aperture
covered by the capital door 22 which may be hinged directly to the capital for
removal.
Capital door 22 may be removably placed over the opening within the capital by
virtue of
door latch 28 thereby allowing access to the interior of the capital and the
various
electronic components therein which may include the ballast, electronic
cabling, optical
