[0001] FIELD OF THE INVENTION
FOR POLE MOUNTED AREA LIGHTS
[0001] FIELD OF THE INVENTION
[0002] The present invention relates to luminaires for road illumination, and more particularly to a mounting system for such luminaires.
BACKGROUND OF THE INVENTION
BACKGROUND OF THE INVENTION
[0003] Currently, conventional luminaires (i.e. lighting units) for road illumination include High Pressure Sodium (HPS) or Metal Halide (MH) light bulb fixtures mounted to the top of a vertical mounting pole. These luminaires are very energy inefficient compared to state of the art light emitting diode (LED) luminaires. LEDs last longer, and consume much less power. Many communities are replacing conventional luminaires with LED
luminaries.
However, there are numerous conventional luminaire models and associated pole mounting hole configurations, which can vary widely by brand and/or by region. As illustrated in Fig. 1, most conventional luminaire designs require the mounting pole 2 to have upper and lower mounting holes 4 and 6, with a conduit hole 8 therebetween (through which the power lines run).
luminaries.
However, there are numerous conventional luminaire models and associated pole mounting hole configurations, which can vary widely by brand and/or by region. As illustrated in Fig. 1, most conventional luminaire designs require the mounting pole 2 to have upper and lower mounting holes 4 and 6, with a conduit hole 8 therebetween (through which the power lines run).
[0004] One problem with designing LED luminaires for replacing conventional luminaires is that different conventional luminaire models have different spacing configurations for the mounting and conduit holes. Specifically, the distance A between the two mounting holes 4/6, and the distance B between the lower mounting hole 6 and the conduit hole 8, vary among the different conventional models. Therefore, no single LED luminaire with any given mounting hole and conduit hole spacing configuration would be compatible with all the various hole spacings found on existing mounting poles. The table in Fig. 2 illustrates numerous examples of mounting hole spacing configurations among the more popular conventional luminaire models. In addition, some of the conventional Atty Dckt No.: 351601-992901 PATENT
luminaires are configured to mount to round mounting poles, while others are configured to mount to square mounting poles (i.e. mounting poles that have a flat mounting surface).
Therefore, one conceivably could need as many as 32 different LED luminaire designs just to accommodate the replacement of those conventional luminaire models identified in Fig. 2.
One alternative is to provide a single LED luminaire mounting hole configuration, and drill new holes into the mounting pole during each conventional luminaire replacement.
However, modifying the mounting pole with each luminaire replacement is time consuming and costly, especially given that the working area is located at the top of a mounting pole high above the road.
100051 There is a need for an LED luminaire design that is compatible with multiple mounting hole configurations.
BRIEF SUMMARY OF THE INVENTION
100061 The aforementioned problems and needs are addressed by the luminaire of the present invention, which includes a housing having a flange and a plurality of LEDs. The flange includes formed therein a plurality of spaced apart holes disposed along a line, a slot disposed along the line, and a central hole disposed along the line and between the slot and the spaced apart holes. The plurality of LEDs are attached to or disposed in the housing.
100071 Another aspect of the present invention is a method of installing a luminaire on a mounting pole. The mounting pole comprises upper and lower mounting holes and a conduit hole disposed therebetween. The luminaire comprises a housing, a plurality of LEDs attached to or disposed in the housing, and a flange attached to or formed as part of the housing. The flange includes formed therein a plurality of spaced apart holes disposed along a line, a slot disposed along the line, and a central hole disposed along the line and between the slot and the spaced apart holes. The method includes installing an upper mounting bolt in the upper mounting hole such that the upper mounting bolt extends from the mounting pole, hanging the luminaire on the upper mounting bolt by inserting the mounting bolt through the slot, sliding the upper mounting bolt along the slot so that the conduit hole and the central hole are at least partially aligned to each other and so that one of the plurality of spaced apart WEST\240740599 1 Atty Dckt No.: 351601-992901 PATENT
holes is aligned to the lower mounting hole, and installing a lower mounting bolt through the lower mounting hole and the one spaced apart hole aligned therewith.

The mounting pole comprises upper and lower mounting holes and a conduit hole disposed therebetween. The luminaire comprises a housing, a plurality of LEDs attached to or disposed in the housing, and a flange attached to or formed as part of the housing. The flange includes formed therein a plurality of spaced apart holes disposed along a line, a slot contiguous with a hole both disposed along the line wherein the hole has a diameter that is greater than a width of the slot, and a central hole disposed along the line and between the slot and the spaced apart holes. The method includes installing an upper mounting bolt in the upper mounting hole such that the upper mounting bolt extends from the mounting pole, installing a nut on the upper mounting bolt, hanging the luminaire on the upper mounting bolt by inserting the mounting bolt and nut installed thereon through the hole and then sliding the upper mounting bolt along the slot, positioning the luminaire relative to the mounting pole such that the conduit hole and the central hole are at least partially aligned to each other and such that one of the plurality of spaced apart holes is aligned to the lower mounting hole, and installing a lower mounting bolt through the lower mounting hole and the one spaced apart hole aligned therewith.

DETAILED DESCRIPTION OF THE INVENTION
[0029] The present invention is an LED luminaire that includes a specially designed mounting flange which is compatible with most mounting hole configurations found on existing mounting poles.
[0030] The mounting flange 10 of the present invention is illustrated in Fig. 3, and includes a universal retrofit mounting hole design. The mounting hole design includes a central hole 12 for accommodating the conduit hole 8 in the mounting pole 2 (i.e. through which the electrical conduit for the LEDs runs), a series of individual mounting holes 14a, 14b, 14c and 14d for matching with the lower mounting hole 6 on the mounting pole 2, and an elongated slot-hole 16 for matching with the upper mounting hole 4 on the mounting pole 2. The central hole 12, mounting holes 14a-14d and slot-hole 16 are disposed along a line L.
The individual mounting holes 14a-14d are closely spaced apart, so that for any given mounting pole configuration, at least one of the individual mounting holes 14a-14d will line up with the lower mounting hole 6 on the mounting pole 2 while allowing sufficient overlap between the central hole 12 and the conduit hole 8 for the conduit to run through. The elongated slot-hole 16 is a combination of a hole 16a and a slot 16b that is contiguous with, and has a smaller width than, the hole 16a (i.e. the width of the slot 16b is smaller than the diameter of the hole 16a). The slot 16b is long enough so that it will line up with the upper mounting hole 4 on the pole 2 when the central hole 12 is aligned to the conduit hole 8 (i.e.
slot 16b has a length that is at least as great as the range of variations in the distance between upper hole 4 and conduit hole 8 of the mounting poles 2 for which the mounting flange 10 will be compatible). By having at least one of the mounting bolts (i.e. the lower mounting bolt) going through an individual mounting hole (e.g. one of holes 14a-14d) instead of a slot, it prevents the unwanted vertical sliding of the luminaire should both mounting bolts come loose over time, which could sever or electrically short the conduit running through the central hole 12 and conduit hole 8.
WEST\240740599 1 Atty Dckt No.: 351601-992901 PATENT
[0031] Fig. 4 illustrates an optional back plate 20 that includes the same mounting hole configuration as the mounting flange 10, except it includes a slot 22 instead of slot-hole 16.
Back plate 20 can be placed within the mounting pole 2 for receiving and securing the mounting bolts (i.e. for extra structural support). The mounting holes 14a-14d of back plate 20 can be threaded for receiving the bolt extending through the corresponding hole 14a-14d of the mounting flange 10 (which would avoid the need for a separate nut). It is preferable to use threaded holes in the back plate 20 instead of threading mounting hole 6 of pole 2 in case the threads get stripped (i.e. easier to replace back plate 20 than re-thread hole 6).
[0032] Figs. 5A-5C illustrate an optional round pole adapter (RPA) 24, which is a plate member having the same mounting hole design as the mounting flange 10. RPA 24 includes a flat front surface 26 (i.e. compatible with the mounting flange 10), and a curved back surface 28 (i.e. compatible with the round surface of the mounting pole). The RPA 24 allows for a more secure mounting of the flat mounting flange 10 to the curved surface of mounting pole 2. Figures 5A-5C illustrate that the RPA 24 is compatible with mounting poles 2 of different diameters (i.e. different portions of the RPA back surface 28 are utilized in an abutting fashion with the pole surface). Specifically, the back surface 28 includes a center portion 28a of greater curvature for engaging with smaller diameter poles, a middle portion 28b of lower curvature for engaging with medium diameter poles, and a rim portion 28c for engaging with larger diameter poles. The mounting flange 10 and RPA 24 can be bolted together (with front surface 26 abutting the mounting flange 10) before installation on the mounting pole using mounting holes 18 on the mounting flange 10.
100331 Fig. 6 illustrates the installation of the LED luminaire 30 onto a round mounting pole 2 using an RPA 24 and a back plate 20. The LED luminaire 30 includes a mounting flange 10 integrally formed as part of the housing 31, a power supply compartment 32, a power supply 34, a power supply compartment door 36, and a plurality of LEDs 38 contained within or attached to housing 31. Fig. 7 illustrates the installation of the same LED luminaire onto a square mounting pole 2 using a back plate 20.
100341 The installation of the LED luminaire 30 onto pole 2 is now described. First, the power compartment door 36 is opened or removed. Then, the optional RPA 24 can be 30 mounted to the mounting flange 10 should it be desired and should the mounting pole be WESTk240740599 1 Atty Dckt No.: 351601-992901 PATENT
round, as shown in Fig. 8. If the luminaire is going to be mounted to a square pole 2, or if it is deemed unnecessary, optional RPA 24 can be omitted. An upper mounting bolt 40 is installed on mounting pole 2 by extending bolt 40 through slot 16b of back plate 20 (if a back plate 20 is used) and through upper mounting hole 4 of pole 2, as illustrated in Figs. 9A and 9B. A nut 41 is placed on or near the end of the bolt 40 as shown. The luminaire is then hung on the upper mounting bolt 40 via the elongated slot 16b of mounting flange 10, as illustrated in Fig. 10. The hole 16a is large enough for the nut 41 on the upper mounting bolt 40 to pass through, so that the luminaire 30 can be hung loosely but securely on the upper mounting bolt 40 by passing the bolt 40 and the nut 41 thereon through the hole 16a and then sliding the luminaire down until the bolt 40 reaches the top end of the slot 16b (i.e. the slot is narrower that the nut 41 so the nut cannot pass through the slot, thus securing the luminaire to the pole in a single action). This allows a single person to conveniently install the luminaire 30. It also frees up both hands of the installer at this stage of the installation so that they can work on the wiring and/or lower bolt installation without having to support or otherwise hold the luminaire 30 in place.
[0035] To finish securing the luminaire 30 to the pole 2, the luminaire 30 is slid upwardly so that central hole 12 of mounting flange 10 is at least partially aligned with conduit hole 8 of pole 2, and so that one of the individual mounting holes 14a-14d is aligned to the lower mounting hole 6 of the pole 2. Then, a lower mounting bolt 42 is inserted through the one aligned individual mounting hole and secured to the pole via lower mounting hole 6 and the corresponding threaded hole in the back plate 20, as shown in Fig. 11. When bolt 42 is tightened, luminaire is held in place. The nut 41 on the upper mounting bolt 40 can be removed and replaced along with a washer and lock washer if desired, without having to manually support the luminaire 30 in place, as shown in Fig. 12. Alternately, nut 40 could be tightened down before the lower mounting bolt 42 is installed. Once the electrical power wiring is connected, the power compartment door 36 can be installed (see Fig.
13) and closed (see Fig. 14).
[0036] It is to be understood that the present invention is not limited to the embodiment(s) described above and illustrated herein, but encompasses any and all variations falling within the scope of the appended claims. For example, references to the WEST\240740599 1 Atty Dckt No.: 351601-992901 PATENT
present invention herein are not intended to limit the scope of any claim or claim term, but instead merely make reference to one or more features that may be covered by one or more of the claims. While mounting flange 10 is illustrated as being integral with the luminaire housing 31, it could be attached thereto as a separate piece. While four mounting holes 14a-14d are shown, a greater or fewer number could be included. RPA 24 could be integrally formed as part of the mounting flange 10 (i.e. surface of flange 10 facing the mounting pole can be curved), as illustrated in Fig. 15. Lastly, slot-hole 16 could instead be just a slot 17, as shown in Fig. 16, which is less preferable because it would require the installation of nut 41 after the luminaire 30 is hung on bolt 40.
WEST\240740599.1
luminaires are configured to mount to round mounting poles, while others are configured to mount to square mounting poles (i.e. mounting poles that have a flat mounting surface).
Therefore, one conceivably could need as many as 32 different LED luminaire designs just to accommodate the replacement of those conventional luminaire models identified in Fig. 2.
One alternative is to provide a single LED luminaire mounting hole configuration, and drill new holes into the mounting pole during each conventional luminaire replacement.

[0031] Fig. 4 illustrates an optional back plate 20 that includes the same mounting hole configuration as the mounting flange 10, except it includes a slot 22 instead of slot-hole 16.
Back plate 20 can be placed within the mounting pole 2 for receiving and securing the mounting bolts (i.e. for extra structural support). The mounting holes 14a-14d of back plate 20 can be threaded for receiving the bolt extending through the corresponding hole 14a-14d of the mounting flange 10 (which would avoid the need for a separate nut). It is preferable to use threaded holes in the back plate 20 instead of threading mounting hole 6 of pole 2 in case the threads get stripped (i.e. easier to replace back plate 20 than re-thread hole 6).

An upper mounting bolt 40 is installed on mounting pole 2 by extending bolt 40 through slot 16b of back plate 20 (if a back plate 20 is used) and through upper mounting hole 4 of pole 2, as illustrated in Figs. 9A and 9B. A nut 41 is placed on or near the end of the bolt 40 as shown. The luminaire is then hung on the upper mounting bolt 40 via the elongated slot 16b of mounting flange 10, as illustrated in Fig. 10. The hole 16a is large enough for the nut 41 on the upper mounting bolt 40 to pass through, so that the luminaire 30 can be hung loosely but securely on the upper mounting bolt 40 by passing the bolt 40 and the nut 41 thereon through the hole 16a and then sliding the luminaire down until the bolt 40 reaches the top end of the slot 16b (i.e. the slot is narrower that the nut 41 so the nut cannot pass through the slot, thus securing the luminaire to the pole in a single action). This allows a single person to conveniently install the luminaire 30. It also frees up both hands of the installer at this stage of the installation so that they can work on the wiring and/or lower bolt installation without having to support or otherwise hold the luminaire 30 in place.
[0035] To finish securing the luminaire 30 to the pole 2, the luminaire 30 is slid upwardly so that central hole 12 of mounting flange 10 is at least partially aligned with conduit hole 8 of pole 2, and so that one of the individual mounting holes 14a-14d is aligned to the lower mounting hole 6 of the pole 2. Then, a lower mounting bolt 42 is inserted through the one aligned individual mounting hole and secured to the pole via lower mounting hole 6 and the corresponding threaded hole in the back plate 20, as shown in Fig. 11. When bolt 42 is tightened, luminaire is held in place. The nut 41 on the upper mounting bolt 40 can be removed and replaced along with a washer and lock washer if desired, without having to manually support the luminaire 30 in place, as shown in Fig. 12. Alternately, nut 40 could be tightened down before the lower mounting bolt 42 is installed. Once the electrical power wiring is connected, the power compartment door 36 can be installed (see Fig.
13) and closed (see Fig. 14).
[0036] It is to be understood that the present invention is not limited to the embodiment(s) described above and illustrated herein, but encompasses any and all variations falling within the scope of the appended claims.

present invention herein are not intended to limit the scope of any claim or claim term, but instead merely make reference to one or more features that may be covered by one or more of the claims. While mounting flange 10 is illustrated as being integral with the luminaire housing 31, it could be attached thereto as a separate piece. While four mounting holes 14a-14d are shown, a greater or fewer number could be included. RPA 24 could be integrally formed as part of the mounting flange 10 (i.e. surface of flange 10 facing the mounting pole can be curved), as illustrated in Fig. 15. Lastly, slot-hole 16 could instead be just a slot 17, as shown in Fig. 16, which is less preferable because it would require the installation of nut 41 after the luminaire 30 is hung on bolt 40.
