DESCRIPTION OF THE INVENTION

(8) The present invention is directed to a light post assembly 10 that permits wiring and other electrical components and communications to extend through a top-mounted luminaire so as to permit electrical power, communications or transmissions above the luminaire and for supporting top mounted electrical components. The light post assembly 10 includes a long hollow pole 12 and a split luminaire 14. The pole 12 is adapted to be mounted to an electrical base cabinet 13 and is conventional. The pole 12 includes an open top which permits wiring, cabling or other electrical or power transmission or communication to pass out from the interior of the pole.

(9) The luminaire 14 is separated into at least two sections which are shown in the figures as first and second sections 16, 18. Each section includes an outer light transmitting cover 20 which is at least partially transparent or translucent. The cover 20 may be made from glass or, more preferably, plastic material such as polycarbonate. The cover 20 is removably attached to a housing 22. The housing 22 has a back portion 24 with a front side 26 and a rear side 28. The front side 26 faces outward toward the cover 20 and may be coated with a white or reflective material to facilitate light reflection. The rear side 28 includes a recess 30 that extends upward from a bottom edge of the housing to a top edge of the housing, thus forming a channel though the housing 22. As shown the housings 22 of the first and second sections 16, 18 may be substantially identical to one another such that the channels 30 form, in combination, a conduit 31 through the assembled housings 22 and luminaire 14.

(10) It is contemplated that in certain embodiments only one of the luminaire sections 16, 18 may have a channel 30 that forms the conduit 31 through the luminaire. However it is preferable that the luminaire sections are mirror images of one another with each having a channel 30 that, in combination, form the conduit 31. In the illustrated embodiment, the channels 30 have a semi-cylindrical shape, however other shapes may be used. The conduit is located in the luminaire so as to align with the open top of the pole. The conduit 31 permits wiring, cabling and/or other components to extend from the pole into and/or through the luminaire to its top.

(11) In a preferred embodiment, a tube or tubular support 34 mounts to the top of the pole 12 and is configured to extend through the conduit 31 to above the luminaire. The tubular support 32 is designed to provide structural support for components mounted above the luminaire, as well as support the luminaire 14 (i.e., provide a structure onto which the luminaire mounts. The tubular support 34 is hollow so as to permit wiring to pass through to the components mounted above the luminaire, as well as providing for wiring to the light sources inside the luminaire. The tubular support 34 includes flanges 32 on the top and bottom of the tubular support center portion 34C. The flanges 32 provide mounting points for attaching the luminaire to the top of the pole. Specifically as shown in FIG. 6, each housing 22 is hingedly attached to the top and bottom flanges 32. At least one upper and one lower corner 22C of each housing 22 includes a hole that receives a bolt 50 that extends through a hole in each flange 32. The bolts 50 are vertically aligned so as to provide a hinge axis about which the housing 22 can rotate. In one embodiment, each housing 22 includes a housing cap 52 that is mounted to (or formed integral with) the top of the housing 22. In this embodiment the hole in the housing 22 through which the bolt extends is formed in the cap 52, providing a stronger support for the housing 22 mount to the flange 32.

(12) As discussed above, the top flange 32 provides a mounting surface for electrical components that are located above the luminaire, such as antenna or other electrical transmitters and/or receivers. Seals 33 may be included to attach a portion of the cover 20 to the flanges 32 of the tube 34 to prevent water entry into the luminaire or the pole. In the illustrated embodiment, the flanges 32 are located on and attached to (or formed integral with) opposite ends of the tubular support 34. The center section 34C of the tubular support sits within the conduit 31 and preferably has an inner diameter of about four inches to fit the necessary wiring. The tube and flanges can be made from a suitable strong material such as aluminum or steel, for providing the structural support for the electrical component, thus eliminating or reducing the need for luminaire housing 22 to provide support for the top mounted electrical components. It should be readily apparent that the tubular support 34 is not needed and the flanges 32 could be formed on the upper and lower ends of the housing. However, the use of a tube 34 permits the housing and luminaire to be lighter since the housing does not need to carry the loads of the components located above the luminaire. In addition, the incorporation of the tubular support 34 permits for ease of assembly by allowing the electrical components to be assembled onto the tube prior to installation.

(13) As shown in FIG. 5, the recesses 30 in the luminaire sections may include chambers 36 formed in the housings for mounting electrical components, such as LED drivers, that may be necessary for controlling or powering the light sources in the luminaire. One or more light sources 38 are mounted in the luminaire. The light sources may be LED arrays. In the illustrated embodiment, the light sources 38 are mounted on a shelf 40 or bracket extending laterally outward from the back portion 24 of the housing 22.

(14) It is also contemplated that, instead of the luminaire mounting to the top of the pole, each of the sections 16, 18 of the luminaire 14 may attach to a side of the pole near the top such that the pole extends through the conduit 31. In such a configuration, the tubular support 34 is not needed and the flanges 32 would be attached to an upper portion of the pole. In this embodiment, the electrical components attach directly to the top of the pole and the electronics and communications pass through the pole. Power for the light sources in the luminaire would extend through a hole or opening in the side of the pole where the luminaire mounts.

(15) In the illustrated embodiment, the housing 22, preferably including the shelves or brackets 40 that extend laterally outward from the back portion 24 of the housing 22 and which support the light sources 38, is made from a one piece cast body which provides for increased heat dissipation. The use of LEDs can lead to increased heat generation, the housing acts as a heat sink, channeling the heat away from the LEDs. As shown in the figures, the housings 22 includes edges 22E that are preferably exposed to the ambient atmosphere. This permits heat dissipation to the outside air.

(16) The split construction of the luminaire permits each section to be designed so that it is individually sealed, thereby preventing water infiltration into each section. As such, each section of the luminaire operates independently of the other and, thus, one section can be under maintenance while the other operates normally.
