Luminaire and improved lighting system

A luminaire includes a housing defined by a pair of sidewalls, a bottom wall, and a first end wall. The first end wall has a first open-ended slot adapted to receive one or more wires. The luminaire also includes a first bracket removably coupled to the first wall to partially close the open-end of the first slot such that a hole remains. The hole is adapted to securely retain the one or more wires. The luminaire further includes a closure coupled to the housing and configured to close the housing. The closure is configured to include one or more light-emitting components.

FIELD

The present disclosure generally relates to lighting systems and, more particularly, to a luminaire configured to facilitate an improved lighting system incorporating a plurality of electrically connected luminaires.

BACKGROUND

Many commercial buildings, parking structures, transportation areas or structures, and the like are equipped with lighting systems that typically include several luminaires or light fixtures configured to illuminate certain areas. Some luminaires with LEDs for example can be powered by drivers that are physically wired to the luminaires. In typical lighting systems, the drivers are located in proximity to the luminaires that they power, in part because this arrangement simplifies the installation and wiring of the components.

These typical lighting systems can prove to be quite difficult to install. When multiple luminaires are powered by the same driver, the wire(s) connecting the driver to the luminaires are conventionally manually fed through openings, for example, drilled through each individual luminaire housing. This typically requires the wire(s) to be inserted into one end of the luminaire housing, pulled through the luminaire housing, and then fed out at the other end. This process is repeated for each of the luminaires until all of the luminaires are connected to the driver. Wiring the luminaires in this way can be labor intensive, time consuming, and frustrating, particularly when the luminaires are installed in difficult-to-reach locations, such as a high ceiling or a high-traffic tunnel. Moreover, this process may need to be partially or fully repeated when one or more components of a luminaire, such as a light-emitting component, need to be replaced.

SUMMARY

One aspect of the present disclosure provides a luminaire that includes a housing defined by a pair of sidewalls, a bottom wall, and a first end wall, the first end wall having a first open-ended slot adapted to receive one or more wires. The luminaire also includes a first bracket removably coupled to the first wall to partially close the open-end of the first slot such that a hole remains. The hole is adapted to securely retain the one or more wires. The luminaire further includes a closure coupled to the housing and configured to close the housing. The closure is configured to include one or more light-emitting components.

Another aspect of the present disclosure provides a lighting system that includes a first luminaire, a second luminaire positioned proximate to the first luminaire, and a bracket. The first luminaire includes a first housing and a first closure coupled to the housing and configured to close the first housing. The first housing is defined by a pair of sidewalls, a bottom surface, and a first end wall, the first end wall having a first open-ended slot. The first closure is configured to include one or more light-emitting components. The second luminaire includes a second housing and a second closure coupled to the second housing and configured to close the second housing. The second housing is defined by a pair of sidewalls, a bottom wall, and a second end wall, the second end wall positioned proximate to the first end wall and having a second open-ended slot. The second closure is configured to include one or more light-emitting components. The bracket is removably coupled to at least one of the first and second end walls to at least one of partially close the open-end of the first slot, such that a first hole remains, and partially close the open-end of the second slot, such that a second hole remains. The first and second holes are adapted to accommodate passage of one or more wires.

Another aspect of the present disclosure provides a transition bracket that includes a body, a first pair of legs, a second pair of legs, a first U-shaped slot, and a second U-shaped slot. The first pair of legs are coupled to and extend from a first side of the body. The second pair of legs are coupled to and extend from a second side of the body opposite the first side. The first U-shaped slot is defined by the first pair of legs. The second U-shaped slot is defined by the second pair of legs.

DETAILED DESCRIPTION

The present disclosure is generally directed to a luminaire configured to facilitate an improved lighting system that is easier, more effective, and less frustrating to maintain and install. One example of such a luminaire includes a housing, a closure, a slot, and a bracket. The housing is defined by a pair of sidewalls, a bottom wall, and a first end wall. The first-end wall defines the slot, which is adapted to receive one or more wires. The closure is coupled to the housing and is configured to close the housing. The closure includes one or more light-emitting components of the luminaire. The bracket can be coupled to the housing to at least partially close the slot and secure the one or more wires therein. So configured, the luminaire can be quickly and easily wired to other components of the lighting system (e.g., a driver box, other luminaires, etc.). Likewise, components of the luminaire, such as the light-emitting components, can be repaired and/or installed without having to re-wire the luminaire, and, in some cases, the entire lighting system. Additionally, when the first bracket is coupled to the housing and the closure is closed, the bracket can seal the luminaire to the IP66 standard, for example, thereby preventing water (e.g., dripping water, spraying water, water jets), other fluids, and/or particulates (e.g., dust) from entering the luminaire.

FIG. 1depicts an exemplary lighting system100that includes a driver box104and a plurality of luminaires108electrically connected to the driver box104. In this example, the driver box104is located remotely from the luminaires108. The driver box104can, for example, be located ten feet, twenty feet, thirty feet, or some other distance from the luminaires108. The driver box104includes a driver112configured to electrically power the luminaires108via one or more conductors116(e.g., one or more wires, one or more cables, and/or one or more other conductors). The driver112can be secured in the driver box104in any number of ways. The plurality of luminaires108can include one or more different types of luminaires, such as, for example, fluorescent, incandescent, plasma, light-emitting diode (LED), or others. As shown inFIG. 1, the luminaires108are arranged in an end-to-end series or arrangement. In some embodiments, a sealing element can be coupled to and disposed between two adjacent luminaires108. In any event, by arranging the luminaires108in an end-to-end series, during installation and/or maintenance of the lighting system100, the one or more conductors116generally pass through one end of a first luminaire108, another end of the first luminaire108, one end of a second luminaire108, another end of the second luminaire108, and so on, as will be described in greater detail below. Typically, such a process involves significant time, labor, and frustration. However, the luminaires108described herein are structured to facilitate a quicker and easier way of installing and/or maintaining luminaires108in an end-to-end arrangement. The luminaires108described herein are also sealed to the IP66 standard, for example, so that fluids (e.g., water) and/or particulates (e.g., dust) are prevented from entering the luminaires108and contacting the components of the luminaires108(e.g., the light-emitting components).

In other examples, the lighting system100can include more than one driver box104, more or less luminaires108, and/or more than one driver112, either in the driver box104or in additional driver boxes104. For example, the driver box104can enclose six (6) drivers112arranged in rows and columns or in some other way and configured to supply electric power to a maximum of twenty-four (24) luminaires108. As another example, the lighting system100can include multiple driver boxes104, such as, for example, when hundreds of luminaires108are necessary.

Although not specifically illustrated herein, the lighting system100can be included or employed in a parking garage (or a floor or section of the parking garage), commercial building (or a portion thereof), roadway, tunnel, or other structure (or a portion thereof), residential home or building, or other indoor or outdoor space or environment. For example, the lighting system100can be included in a tunnel or other type of covered roadway through which traffic can pass. As briefly mentioned above, the driver box104can be located remotely from each of the luminaires108to which it (and more specifically its driver112) supplies electric power. The luminaires108can thus be installed in an end-to-end series on the ceiling of the tunnel, while the driver box104can be located in a separate control room, on one of the sides of the tunnel, near a ground level of the tunnel, or in another location. Generally, the more that vehicles reduce their speed prior to or upon entering the tunnel, the higher the risk for accidents. Accordingly, adequate and proper lighting in such tunnels is imperative to reduce lighting contrast between the outside of the tunnel and the interior of the tunnel.

FIGS. 2 and 3illustrate an exemplary luminaire200that can be included in the lighting system100. The luminaire200has an elongated housing204and a closure208rotatably coupled to the housing204. The housing204, which is made entirely of stainless steel (e.g., 316 Stainless Steel, 304 Stainless Steel), is generally defined by a first end wall212, a second end wall216opposite the first end wall212, a pair of sidewalls220that extend longitudinally between the first and second end walls212,216, and a bottom wall224. The closure208in this example is a door rotatably coupled to the housing204via a plurality of hinges (not visible inFIGS. 2 and 3) and, when in the closed position shown inFIG. 3, can be secured to the housing via a plurality of latches228. The latches228are, as shown inFIG. 2, rotary latches, but can, in other embodiments be a different type of latch or lock (e.g., a cam lock, a spring latch). The closure208has a length that is substantially equal to a length of the sidewalls220, such that the closure208is configured to cover, and completely enclose, the housing204. The closure208includes a chamber232in which one or more light-sources, such as, for example, one or more LEDs, can be disposed, a gasket234surrounding the chamber232, and a covering236(FIG. 3) that overlies and encloses the chamber232. The gasket234is coupled to an underside of the closure208adjacent a perimeter edge of the closure208and is configured to facilitate sealing of the chamber232when the closure208is closed. The covering236is substantially flat and includes a frame238surrounding a lens240. The frame238is made of stainless steel, but can be made of a different material. The lens240can be made of glass, plastic (e.g., acrylic plastic, polycarbonate plastic), or some other material.

In other embodiments, the housing204and/or the closure208can be constructed differently. The housing204can have a different size, shape, and/or be made of one or more materials other than or in addition to stainless steel. In one version, the housing204can have a circular shape defined by a bottom wall and a side wall or perimeter edge. In other versions, the housing204can have a different shape. Alternatively or additionally, the closure208can have a different size and/or shape and/or be coupled to the housing204in a different manner. For example, while the closure208is described as being a door, the closure can be a cover (e.g., a cover panel), lid, or other closure device. While the closure208is described as being rotatably connected to the housing204, in other versions, the closure208may be slidably coupled to the housing204or not connected to the housing204at all except for the latches228. As another example, the covering236can have a different shape (e.g., can be curved), a different size, or be made of one or more different materials.

FIG. 4illustrates further details about the first end wall212. The first end wall212has a laterally-extending top portion300, longitudinally-extending side portions304, and a laterally-extending bottom portion308. The first end wall212also includes or defines a first open-ended slot312configured to receive one or more conductors. In this example, the open-ended slot312has a U-shape and is upwardly open toward the top portion300of the first end wall212(and in a direction toward the closure208).

In other examples, the first end wall212can be constructed differently. The shape and/or size of the top portion300, the side portions304, and/or the bottom portion308can vary. Likewise, the open-ended slot312can have a different shape. For example, the slot312can be open in or toward a different direction (e.g., toward one of the side portions304) and/or have a circular shape, a rectangular shape, an irregular shape, or other shape.

Although not specifically depicted herein, the second end wall216illustrated inFIGS. 2 and 3can be identical to the first end wall212, with the same components referenced by common reference numbers. In other words, the second end wall216, which has a top portion identical to the top portion300, side portions identical to the side portions304, and a bottom portion identical to the bottom portion308, includes or defines a second-open ended slot (not shown) that is identical to the first open-ended slot312.

FIG. 5illustrates a first bracket350that can be removably coupled to the first wall212to partially close the open-end of the first slot312to facilitate a seal with the closure208when in the closed position, as will be described in greater detail below. The first bracket350can be made of the same material as the housing204, which in this example is stainless steel (e.g., 316 Stainless Steel, 304 Stainless Steel). The first bracket350has a body354, first and second legs358, a first slot362, first and second feet366, third and fourth legs370, a second slot (not visible inFIG. 5), and third and fourth feet374.

The body354of this version of the bracket350has a generally rectangular shape with a top side376, an underside (not shown), and a perimeter edge378. The body354also includes a vertical sealing wall380that projects or extends upwardly from a central portion of the top side376. The first and second legs358extend downwardly from one side of the perimeter edge378of the body. The first slot362is generally defined by the first and second legs358. In this example, the first slot362has a U-shape and opens in a downward direction (toward the feet366), such that the first slot362has a shape that corresponds to or is complementary with the shape of the slot312. The first and second feet366project outwardly from a bottom end364of the first and second legs358, respectively. The first and second feet366can project outwardly at a 90 degree angle relative (i.e., perpendicular) to the body354and, more particularly, the bottom end364of the first and second legs358, respectively, or at a different angle (e.g., greater than 90 degrees, less than 90 degrees). Each of the first and second feet366includes or defines a semi-circular shaped notch386configured to receive a coupling means (e.g., a fastener). The third and fourth legs370are coupled to and extend downwardly from the perimeter edge378, but do so from an opposite side of the edge378than the first and second legs358. The second slot, which is not visible inFIG. 5, is generally defined by the third and fourth legs370, but is otherwise identical to the first slot362. The third and fourth feet374project outwardly from a bottom end of the third and fourth legs370. Like the first and second feet366, the third and fourth feet374can project outwardly at a 90 degree angle relative to the body354, or at a different angle. Though not depicted inFIG. 5, each of the third and fourth feet374includes or defines a notch386, which, as noted above, is configured to receive a coupling means (e.g., a fastener). So configured, the first and second legs358and the third and fourth legs374form or define a gap390therebetween.

In other examples, the first bracket350can be constructed differently. The first bracket350can, for example, be made of a different material than the housing204. The shape and/or size of the body354, the legs358, the feet366, the legs370, and/or the feet374can vary. The first slot362and/or the second slot can have a different shape. For example, the first slot362and/or the second slot can open in or toward a different direction (e.g., toward the body354) and/or have a circular shape, a rectangular shape, an irregular shape, or other shape. In other examples, the feet366and/or the feet374can include a different sized and/or shaped notch or can include a coupling means (e.g., a snap component) instead of the notch386. In yet another example, the first bracket350need not include the feet366and/or the feet374. Additionally, in other examples, the sealing wall380may not extend up from the top side376, but rather, may be the top side376of the body354. Other sealing configurations are also intended to be within the scope of the present disclosure.

Although not specifically depicted herein, a second bracket that is structurally identical to the first bracket350, with the same components referenced by common reference numbers, can be coupled to the second wall216to partially close the open-end of the second slot, as will be described in greater detail below.

With reference back toFIG. 2, when the luminaire200is installed in the appropriate location (e.g., on the ceiling of a tunnel), a conductor400(e.g., a wire, cable, and/or other connection means) can be used to connect the driver box104to the luminaire200. Typically, the luminaire200is installed upside down relative to the orientation shown inFIG. 2. With the closure208unlocked and rotated (e.g., by gravity) to the open position shown inFIG. 2, the conductor400can first be disposed through, and seated or arranged in, the first open-ended slot312, such that the conductor400is disposed in and extends through the housing204of the luminaire200. The conductor400can, in turn, be connected to the one or more light-sources disposed in the chamber232of the closure208, using any known manner, such that the driver box104(via the driver112) is configured to supply power to the luminaire200, particularly the one or more light-sources disposed in the chamber232. The conductor400can then be disposed through, and seated or arranged in, the second open-ended slot defined in the second end wall216.

It will be appreciated that when the lighting system100includes a plurality of luminaires200, the above-described process can be repeated for one, some, or all of the luminaires200in the lighting system100. It will also be appreciated that when the luminaire200is part of an end-to-end or continuous run of luminaires200, additional conductors400can be disposed through, and seated or arranged in, the first open-ended slot312and the second open-ended slot in a similar way. Accordingly, the driver box104(via one or more drivers112), using these additional conductors400, can be configured to supply power to one or more other luminaires200, such as luminaires200that are upstream or downstream of the luminaire200.

Finally, it should be appreciated that gravity will conventionally pull the one or more conductors400down and away from the luminaire200. Thus, temporary connectors (not shown), such as, for example, one or more conductor clamps, can be employed to temporarily secure the one or more conductors400in these positions. The one or more conductors400can then be more permanently secured or trapped in these positions using the first bracket350and the second bracket, which then also provides the sealing wall380for sealing against the closure208when closed. The first bracket350can be coupled to the first end wall212to partially close the open-end of the first slot312. Specifically, the body354of the first bracket350can be positioned over the top portion300of the first end wall212, with the first and second legs358disposed inward of the first end wall212and the third and fourth legs370disposed outward of the first end wall212. In other words, the first end wall212can be positioned within the gap390formed between the first and second legs358and the third and fourth legs370of the first bracket350. The body354of the first bracket350can contact a portion of the top300of the first end wall212. Friction between the first end wall212and the legs358,370can at least initially hold or retain the body354in this position. In some embodiments, the one or more temporary connectors can, in turn, be removed. In other embodiments, one or more of the temporary connectors can remain disposed within the housing204to facilitate the secure and orderly retention of the one or more conductors400therein.

The first bracket350can be secured in this position by securing the first and second legs358to the housing204. In this embodiment, a plurality of fasteners (e.g., screws, rivets, adhesives, bolts, PEM studs) can be inserted into the notches386formed in the first and second feet366to secure the first and second feet366to the bottom wall224of the housing204In other embodiments, the first and second legs358can be secured in a different way and/or to a different portion of the housing204. For example, the gap390can be sized so that friction between the first end wall212and the first and second legs358is all that is required to secure the first and second legs358to the housing204. As another example, the first and second legs358can be snapped, glued, or attached in some other way to the housing204. In yet another example, the first and second feet366can be snapped, glued, or attached in some other way to the bottom wall224and/or the first and second feet366can be secured to the first end wall212and/or the sidewalls220of the housing204.

It will be appreciated that the first bracket350can be removed from the first end wall216in a similar manner, such as, for example, when one or more conductors400need to be replaced. It will also be appreciated that the second bracket can be coupled to the second end wall216in a similar manner. Likewise, it will be appreciated that when the lighting system100includes a plurality of luminaires200(e.g., the luminaire200is part of an end-to-end or continuous run of luminaires200), first and/or second brackets can be similarly coupled to first and/or second walls212,216of one or more of these luminaires200. When, for example, the lighting system100includes another luminaire200immediately adjacent to the luminaire200described above, and the one or more conductors400are disposed through, and seated in, this second luminaire200as described above, the first bracket350can also be coupled to the first or second wall of the second luminaire200(depending upon how the luminaire is oriented) to partially close the open-end of the first or second slot of this second luminaire200. This would typically, but need not, be done at the same time as the first bracket350is coupled to the first end wall212of the luminaire200, as described above. In turn, the third and fourth legs370can be secured to the housing204of this second luminaire200in a similar manner as the first and second legs358are secured to the housing204of the first luminaire200. Thus, in some embodiments, the same bracket can be used in connection with two different luminaires200.

FIG. 6depicts apartial view of one end of the luminaire200when the first bracket350is coupled to the first end wall212as described above. As shown inFIG. 6, because the shape of the slot362of the first bracket350corresponds to the shape of the slot312of the end wall212, the first bracket350, when coupled to the first end wall212, closes off the previously open-ended portion of the first slot312, such that a substantially circular hole450is formed or remains. The circular hole450is smaller in size than both of the slots312,362. The one or more conductors400, by virtue of being seated in the first slot312before the first bracket350was coupled to the first end wall212, are seated and securely retained or trapped in the circular hole450. At the same time, with reference toFIG. 7, the vertical sealing wall380of the first bracket is configured to act as a seal surface for one end of the luminaire200. When the closure208is closed, an end portion235of the gasket234is disposed in sealing engagement against the sealing wall380, such that the two can cooperate to seal the luminaire200. The gasket234and the sealing wall380can seal the luminaire200to the IP66 standard, for example, such that water, other liquids, or particulates (e.g., dust) from are prevented from entering an interior of the luminaire200, particularly where the one or more light sources are disposed in the chamber232of the closure208and where the one or more conductors400pass through the housing204. In the embodiments in which the first bracket350is also coupled to the first or second end wall of an immediately adjacent second luminaire200, the first bracket350, when coupled to this first or second end wall, can close off the previously open-ended portion of the slot of the first or second end wall, such that a substantially circular hole, similar to the hole450, is formed or remains. The one or more conductors400, by virtue of being seated in the slot of the first or second end wall before the first bracket350was coupled to the second luminaire200, are seated and securely retained or trapped in this circular hole. By virtue of the immediate adjacency of the first or second end wall to the first end wall312, the vertical sealing wall380of the first bracket can also act to seal one end of the second luminaire200to the IP66 standard as well, thereby preventing, for example, water, other liquids, or particulates (e.g., dust) from entering an interior of the second luminaire200.

FIG. 8Adepicts an example in which the vertical sealing wall380of the first bracket350can act to seal one end of the first luminaire200and an adjacent end of the second luminaire200. In addition, a sealing element (e.g., a gasket), such as the sealing element550illustrated inFIG. 8B, can be coupled to and disposed between the two immediately adjacent luminaires200. So disposed, the sealing element can seal the space or area between the two immediately adjacent luminaires200. In the example depicted inFIG. 8A, the sealing element550is sandwiched between end walls212of the adjacent luminaires200. In other versions, the sealing element550can be glued, snapped, fastened, or secured in some other way to the end walls212.

Although not depicted herein, it will be appreciated that the second bracket can perform these same functions as well—the second bracket can close off the previously open-ended portion of the second slot, such that a substantially circular hole identical to the hole450is formed or remains, in which the one or more conductors400can be seated and securely retained; and a vertical sealing wall of the second bracket, identical to the vertical sealing wall380, can act to seal the other end of the luminaire200in a similar manner.

When the luminaire200is positioned at a beginning of an end-to-end run of luminaires (i.e., the luminaire200is the luminaire most proximate to the driver box104) or the luminaire200is positioned at an end of the end-to-end run of luminaires, a transition box500can be coupled to the luminaire200.FIG. 9depicts one example of such a transition box500. The transition box depicted inFIG. 9includes a top surface504, a pair of first walls508, a pair of second walls512, and a recessed underside514defined by and between the walls508,512(seeFIG. 2). The pair of walls508are coupled to and extend downward from a first portion of the transition box500. The walls508are parallel to, but spaced apart from, one another, such that a gap516is defined or formed therebetween. Each of the walls508is structurally similar to one side of the first bracket350. In other words, each wall508includes a pair of downwardly extending legs520and a U-shaped slot524defined by the legs520. The U-shaped slot524of each of the walls508, like the slot362of the bracket350, corresponds to the slot312. The walls512are coupled to and extend downward from a second portion of the transition box500. The walls512are parallel to, but spaced apart from, one another, such that a gap528is defined or formed therebetween. Each of the walls512is identical to the walls508. As such, each wall512includes a pair of downwardly extending legs and a U-shaped slot, none of which is visible inFIG. 9. The U-shaped slot of each of the walls512, like the slot362of the bracket350, corresponds to the slot312.

In other embodiments, the transition box500can be constructed differently. More specifically, the shape and/or size of the top surface504, the walls508, and/or the walls512can vary. In some embodiments, the transition box500only include the walls508or the walls512, not both.

With reference back toFIG. 2, the transition box500can be coupled to the first end wall212or the second end wall216of the luminaire200. In the example depicted byFIG. 2, a first portion506of the transition box500(seeFIG. 9) is positioned over the top portion300of the first end wall212or the second end wall216, such that the first end wall212or the second end wall216is disposed in the gap516, between the walls508. Because the shape of the slot524corresponds to the shape of the slot312of the first end wall212or the second end wall216, the transition box500closes off the previously open-ended portion of the first slot312, such that a substantially circular hole, similar to the hole450described above, is formed or remains. The one or more conductors400are seated and securely retained or trapped in this substantially circular hole. At the same time, the connection between the first end wall212or the second end wall216and the transition box500serves to seal the luminaire200to the IP66 standard, for example, as the first bracket350normally would.

In other embodiments, the transition box500can be coupled (e.g., mounted, attached) to the first end wall212or the second end wall216in a different way. The transition box500can, for example, be coupled to the exterior surface of the first end wall212or the second end wall216. In other examples, the transition box500can be coupled to a different portion of the luminaire200(e.g., the first bracket350).

When the luminaire200is positioned at the beginning of the end-to-end run of luminaires and the transition box500is coupled to the first end wall212, the transition box500effectively serves as the conduit connection point between the driver box104and the luminaire200(as well as any other downstream luminaires200). In this case, any conductors400connecting the driver box104with the luminaire200and/or any downstream luminaires200can pass through the substantially circular hole described above and the recessed underside512of the transition box500. When, as shown inFIG. 2, the luminaire200is positioned at the end of the end-to-end run of luminaires and the transition box500is coupled to the second end wall216, the transition box500can store any excess conductors400. In some cases, the transition box500can also serve as a conduit pass-through for conductors400for one or more other runs of luminaires (e.g., runs of luminaires that are positioned far from the driver box104). It will also be appreciated that the orientation of the luminaire200can be changed, such that the transition box500can be coupled to the second end wall216when the luminaire200is positioned at the beginning of the end-to-end run or the transition box500can be coupled to the first end wall212when the luminaire200is positioned at the end of the end-to-end run. It will also be appreciated that the orientation of the transition box500can be changed, such that the second portion of the transition box500can be positioned over the top portion300of the first end wall212or the second end wall216.

Based on the foregoing description, it should be appreciated that the luminaires described herein can be installed and maintained in a more efficient, more effective, and less frustrating way. For example, the luminaires described herein can be quickly and effectively wired to one another and/or other components in a lighting system. As another example, components of the luminaires described herein, such as, for example, light-emitting components, can be installed and/or repaired without having to re-wire the entire lighting system. At the same time, the luminaires described herein can also include a sealing surface that acts to seal the luminaires to the IP66 standard, for example, such that the luminaires described herein are sealed against water, other liquids, and/or particulates (e.g., dust).

This detailed description is to be construed as examples and does not describe every possible embodiment, as describing every possible embodiment would be impractical, if not impossible. One could implement numerous alternate embodiments, using either current technology or technology developed after the filing date of this application.
