Description

LUMINAIRE HOUSING

BACKGROUND

[0001] The present subject matter relates to general illumination lighting, and more particularly, to arrangements for outdoor luminaires such as street lights.

[0002] Typically, outdoor luminaires such as street lights are used to illuminate large areas of open space, such as parking lots, parking garages, roadways, parks, pathways or the like. Such luminaires are typically mounted on a support such as a pole or the like. Advances in light emitting diode (LED) technology have resulted in wide adoption of luminaires that incorporate such devices. LEDs are typically used with supplementary optical devices such as lenses, reflectors, optical waveguides, and combinations thereof that significantly improve illumination distribution for particular applications. LED luminaires provide economic and operational benefits as compared to conventional incandescent and fluorescent lighting leading to the widespread adoption of LED based luminaires.

[0003] The widespread adoption of such luminaires has resulted in a need for a luminaire housing that is easy to install and maintain and that is cost effective.

SUMMARY

[0004] In some embodiments, a luminaire comprises a housing comprising a base and a cover movably mounted to the base at a hinge. The hinge comprises a shaft that defines an axis of rotation of the hinge. A first receptacle is formed on one of the base and the cover and a second receptacle formed on the other one of the base and the cover where the first receptacle and the second receptacle receive the shaft. A first plate is fixed to one of the base and the cover to fix the position of the shaft relative to the one of the base and the cover. A second plate is fixed to the other one of the base and the cover for retaining the shaft on the other one of the base and cover such that the shaft is rotatable relative to the other one of the base and the cover.

[0005] The first plate and the second plate may comprise holes for receiving threaded fasteners. The first plate may be fixed to the one of the base and the cover by a first fastener that engages a first unthreaded bore and the second plate may be fixed to the other one of the base and the cover by a second fastener that engages a second unthreaded bore. An interference fit may be created between the first plate and the shaft. A second shaft may be provided that together with the shaft defines the pivot axis of the hinge. A third receptacle may be formed in one of the base and the cover and a fourth receptacle may be formed in the other one of the base and the cover, the third receptacle and the fourth receptacle receive the second shaft; a third plate may be fixed to one of the base and the cover to fix the position of the second shaft relative to the one of the base and the cover; and a fourth plate may be fixed to the other one of the base and the cover for retaining the second shaft on the other one of the base and cover such that the second shaft is rotatable relative to the other one of the base and the cover. The first shaft and the second shaft may be coaxially aligned.

[0006] In some embodiments, a luminaire comprises a housing and a fitter mechanism for adjusting a tilt angle of the housing. The fitter mechanism comprises a connection member configured to be attached to a support structure where the connection member is secured to a hub. The hub defines a cog wheel centered on an axis of rotation of the housing. A pawl is mounted on the housing where the pawl is movable between a first position where the pawl engages the cog wheel to fix the position of the housing relative to the hub and a second position where the pawl is disengaged from the cog wheel to allow relative movement between the housing and the hub. An adjustment member selectively controls movement of the pawl between the first position and the second position. The adjustment member is accessible from a first side of the housing.

[0007] The adjustment member may comprise a threaded member threadably engageable with one of the base and the cover where the adjustment member may be accessible through a hole in the other one of the base and the cover. The adjustment member may extend through a bore formed in the pawl. The cog wheel may comprise a plurality of teeth forming a beveled cog wheel. The housing may comprise a bearing surface that engages the cog wheel when the pawl is in the first position. An angle indicator may be provided that displays a tilt angle of the housing. The angle indicator may comprise an engagement member on the fitter mechanism that is selectively engageable by an engagement member on the housing. The fitter mechanism may allow adjustment of the housing between approximately -20 ⁰ and approximately +110 ⁰ relative to the connection member. The housing may comprise a base and a cover movably mounted to the base between a closed position and an open position and a locking member engageable with the pawl to lock the cover in the closed position. The locking member may comprise a threaded member that threadably engages an unthreaded bore in the pawl. The adjustment member and the locking member may be disposed in close proximity to one another, where the adjustment member and the locking member may be accessible from the first side of the luminaire and from the same direction of handling.

[0008] In some embodiments, a method of installing a luminaire comprising a housing having a base and a cover movable relative to the base between an open position and a closed position comprises: operating an adjustment member from a first side of the housing to move a pawl carried by the housing between a first position where the pawl engages a stationary cog wheel to fix the position of the housing and a second position where the pawl is disengaged from the cog wheel to allow relative movement of the housing; rotating the housing to a desired tilt angle when the pawl is in the second position; moving the pawl to the first position when the housing is in the desired position; operating a locking member from the first side of the housing between a first position where the cover is locked to the base and a second positon where the cover is unlocked from the base wherein the adjustment member and the locking member are disposed in close proximity to one another, and wherein the adjustment member and the locking member are accessible from the same direction of handling.

DETAILED DESCRIPTION

[0024] Embodiments of the present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like numbers refer to like elements throughout. [0025] Referring to FIGS. 1 through 4, the luminaire 1 comprises a housing 2 that encloses the internal components of the luminaire to isolate the components from the external environment. The housing 2 may be a sealed, waterproof enclosure that protects the internal components from weather, debris and the like. The housing 2 comprises a base 4 and a cover 6 that is movably mounted relative to the base 4 such that the cover 6 can be rotated between an open position (FIG. 4) where access to the internal components of the luminaire 2 is provided and a closed position (FIGS. 1 - 3) where the internal components are isolated from the ambient environment.

[0026] The luminaire 1 is a LED based luminaire and may comprise components typically provided in a LED luminaire. For example, the luminaire 1 may comprise a waveguide 8 that receives light emitted by a plurality of LEDs (not shown) and that emits the light in a desired pattern. The waveguide 8 may provide other functions such as the mixing of the light emitted by the LEDs. A LED driver or power supply may be contained in a driver housing 10 that is mounted to the underside of cover 6. The driver circuitry provides critical current to the LEDs for driving the LEDs at a desired lumen output and color. Other electronics may be provided on the underside of the cover 6 such as SPD 12 and knife switch 14. Current may be delivered to the driver circuitry via conductors such as wires (not shown) and electrical connectors 18 on the cover 6 and base 4. In the illustrated embodiment, at least some of the components, including the power supply for the LEDs, are mounted on the cover 6 for ease of access; however, some or all of the components may be mounted in the base 4. A locking rod 20 may be provided for ease of access. The locking rod 20 may be pivotably mounted to the base 4 and may be rotated to the locked or extended position as shown in FIG. 4 to engage a stop 22 on the cover 6 to hold the cover 6 in the open position. The locking rod 20 may be rotated to an unlocked or stored position in the base 6 when not in use. It is to be understood that the locking rod 20 could also be pivotably mounted to the cover 6 and engage a stop on base 4.

[0027] A seal 24 may be provided around the opening 26 in the base 6. The seal is engaged by a flange 28 formed on the underside of the cover 6 to form a liquid-tight seal between the cover 6 and base 4. The seal 24 may be provided on the cover 6 rather than on the base 4 with the flange 28 being formed on the base 4. [0028] The cover 6 is pivotably connected to the base 4 at a hinge 30. The hinge

30 avoids machining on either the base 4 or cover 6, and provides a simple to install and low cost hinge. Referring to FIGS. 5 through 9, the hinge 30 is defined by two hubs 32, 34 that are coaxially aligned to define the axis of rotation A-A (Fig. 4) of the hinge 30. The hubs 32, 34 are identical to one another such that the structure of hub 32 will be described in detail with it understood that hub 34 has substantially the identical structure.

[0029] Hub 32 comprises a shaft 40 that defines the axis of rotation A-A of the hinge 30. The shaft 40 extends for substantially less than the full width of the cover 6. The shaft 40 of hub 32 is positioned at one lateral side of the cover 6 with the shaft 40 of hub 34 positioned at the other lateral side of the cover 6. The shafts 40 of hubs 32 and 34 are coaxially aligned to define the axis of rotation A-A of the hinge 30 along the longitudinal axes of the shafts 40. A first plate 42 and a second plate 48 are provided that are separate from the shaft 40. The plate 42 includes a through-hole 44 that is engageable by a screw 46 as will herein after be described. The through-hole 44 is offset from the center of the plate 42 such that the plate defines a retention area 42a to one side of through-hole 44. A second plate 48 is also provided that includes a through-hole 50 that is engageable by a screw 52 as will herein after be described. The through-hole 50 is offset from the center of the plate 48 such that the plate 48 defines a retention area 48a to one side of through-hole 50.

[0030] Referring to FIG. 8, the cover 6 includes receptacles 56 for receiving the shaft 40 and the base 4 includes a receptacle 57 for receiving the shaft 40. The receptacle 57 is positioned between the receptacles 56 in an interdigitated manner to form the knuckles of the hinge 30. The receptacles 56 and 57 closely receive the shaft 40. In the illustrated embodiment, each receptacle 56 is formed by elongated semi-cylindrical cradles 56a having fingers 56b that extend substantially perpendicularly from the cradles 56a. Flat support surfaces 56c are formed between the fingers 56b on at least one of receptacles 56 for receiving and supporting plate 48. The support surfaces 56c are arranged on opposite sides of the shaft 40 and are positioned slightly below the exposed surface of shaft 40 such that when plate 48 is positioned against support surfaces 56c the plate 48 interferes with the shaft 40. The receptacle 57 is formed by a pair of spaced semi-cylindrical cradles 57a that hold the shaft 40 in the receptacle 57. A support surface 57b is arranged on one side of the shaft 40 for receiving and supporting plate 42. The support surface 57b is positioned slightly above the exposed surface of shaft 40 such that when plate 42 is positioned against support surfaces 57b the plate 42 does not interfere with the shaft 40.

[0031] The shaft 40 is inserted into receptacles 56 formed in cover 6. The plate

48 is positioned with through-hole 50 disposed over the bore 60 and retention area 48a positioned over shaft 40. Screw 52 is inserted through through-hole 50 and is screwed into bore 60. The bore 60 is a self-threading bore such that screwthreads do not have to be pre-formed, such as by machining, in the bore 62. When the screw 52 is fully tightened, the plate 48 is pressed against support surfaces 56c. Because the support surfaces 56c are arranged below the shaft 40, when screw 52 is fully tightened, the retention area 48a of plate 48 is brought into tight engagement with the shaft 40 such that the position of shaft 40 is fixed relative to the cover. The hinge components are configured such that the retention area 48a of plate 48 creates a tight interference fit with the shaft 40 and fixes the postion of the shaft relative to the cover 6.

[0032] The shaft 40 is then inserted into receptacle 57 formed on the housing base

4. The plate 42 is positioned with through-hole 44 disposed over the bore 62 and retention area 42a disposed over the shaft 40. Screw 46 is inserted through through-hole 44 and is screwed into bore 62. The bore 62 is a self-threading bore such that screwthreads do not have to be pre-formed, such as by machining, in the bore 62. When the screw 46 is fully tightened the plate 42 is tightened against support surface 57b. A small clearance is provided between the retention area 42a and the shaft 40 such that the shaft 40, while retained in the receptacle 57 by plate 42, is not fixed to the base 4 such that the base 4 may rotate relative to the shaft 40.

[0033] The cover 6 may be rotated between open and closed positions by lifting the free end 6a of the cover 6 such that the shaft 40, which is fixed in position relative to the cover 6, is rotated in receptacles 57 formed on the base 4 such that the cover 6 rotates about the longitudinal axis of the shafts 40. It is to be understood that order of assembly may vary from that described above. Moreover, the components may be reversed such that the hinge components that are described as being mounted to the base 4 may be mounted to the cover 6 and the hinge components that are described as being mounted to the cover 6 may be mounted to the base 4.

[0034] The hinge 30, using the two hubs 32, 34 as described above, provides a secure hinge that is easy to assemble and is cost effective to manufacture and does not require machined parts. The hinge 30 also provides an improved appearance for the luminaire 1 because the hinge and the fasteners are hidden from view from the outside of the housing 2 as shown in FIG. 1.

[0035] The end of the luminaire 1 opposite the waveguide 8 includes a fitter mechanism 80 for connecting the luminaire 1 to the support structure as shown in FIGS.

1, 4 and 10 through 19. The fitter mechanism 80 comprises a connection member 82 for securing the luminaire 1 to a support structure. In the illustrated embodiment, the fitter mechanism 80 is designed to be attached to a cylindrical stanchion such as a cylindrical pole where the connection member 82 comprises a cylindrical receptacle 82a for receiving the pole. An adapter 82b may be used to accommodate poles having smaller dimensions than the receptacle 82a. Bolts 87 may be inserted through the wall of the receptacle 82a to engage the pole to secure the fitter mechanism 80 to the support structure. In the illustrated embodiment, the fitter mechanism 80 is provided with a cylindrical receptacle 82a for receiving a cylindrical pole. However, the receptacle 82a may be shaped other than cylindrically to match the shape of the support pole. Moreover, the connection member 82 may be replaced by a flange or other attachment structure for attaching the luminaire 1 to a wall or a support structure other than a pole.

[0036] The fitter mechanism 80 is integrated with the luminaire 1 such that the installer does not have to install a separate fitter to the luminaire 1 during installation of the luminaire 1 to the support structure. The fitter mechanism 80 is adjustable to allow the installer to adjust the plane of the luminaire relative to the support structure as shown in FIG. 17. The fitter mechanism 80 allows the luminaire 1 to pivot about a horizontal axis B-B (FIG. 14).

[0037] The fitter mechanism 80 comprises a hub 84 to which the connection member 82 is fixed. An adjustment and a locking mechanism 86, 88 is located on each end of hub 84. The adjustment and locking mechanisms 86 and 88 are identical to one another such that the structure of adjustment and a locking mechanism 86 will be described in detail with it understood that adjustment and a locking mechanism 88 has substantially the identical structure.

[0038] The adjustment and a locking mechanism 86 comprises a circular cog wheel 90 formed on the lateral end of hub 84. The circular cog wheel 90 comprises a series of teeth 90a disposed in a circle centered on axis B-B. The teeth 90a form a beveled cog wheel where the teeth 90a are disposed at angle of approximately 30 degrees relative to axis B-B. In the illustrated embodiment, the teeth 90a are formed as generally triangular teeth; however, the teeth may have any suitable shape.

[0039] The base 4 of housing 2 is formed with spaced two arms 94 that receive the fitter mechanism 80 therebetween. Each arm 94 includes a semicircular bearing surface 96 that engages a bottom portion of the associated circular cog wheel 90. Referring to FIG. 19 each bearing surface 96 may be provided with teeth 96a that mate with the teeth 90a that form the circular cog wheel 90. In the illustrated embodiment, the teeth 96a are positioned at approximately the “six o’clock” position of the cog wheel 90. Whether teeth 96a are formed on bearing surfaces 96 and the number of teeth provided may depend on the holding force required to maintain the luminaire housing 2 in the desired position.

[0040] A movable pawl 98 is positioned between the base 2 and the cover 6.

Referring to FIG. 18, the movable pawl 98 comprises two sets of teeth 98a that are arranged in a semi-circle and are positioned to releasably engage a top portion of the cog wheel 90. In the illustrated embodiment, the two sets of teeth 98a are arranged at approximately the “two o’clock and “ten o’clock” positons relative to the cog wheel 90 such that a spaced three-point contact is established between the cog wheel 90 and the three sets of teeth 96a, 98a where the teeth are space approximately 120 degrees from one another.

[0041] The movable pawl 98 is formed as part of block 100. Block 100 has two bores 102, 104 formed therein that extend substantially parallel to one another. The first bore 102 is unthreaded and extends through the block 100 and the second bore 104 is also an unthreaded bore. Because all of the screws and/or bolts used in the housing are self- threading, the bores may be used directly from the die cast process without the need for any machining operations. The pawl 98 as shown in FIG. 18 includes a duplicate second bore 104a such that the same component may be used on both the left and right sides of the hub 84; however, the duplicate bore 104a may be eliminated and a unique pawl component may be used on each side of the hub 84.

[0042] The first bore 102 receives a selfthreading member 106 such as a bolt that extends through the first bore 102 and threadably engages an unthreaded hole 108 formed on base 4. The threaded member 106 holds the movable pawl 98 in position in the luminaire housing 2. It will be appreciated that when the threaded member 106 is screwed tightly into the hole 108 the teeth 98a of pawl 98 are moved into engagement with the teeth 90a of cog wheel 90 and the teeth 90a of cog wheel 90 are forced into engagement with teeth 96a. In this locked position, the luminaire housing 2 cannot rotate relative to the fitter mechanism 80 and the angular position of the luminaire housing 2 is fixed. When the threaded member 106 is loosened, the teeth 98a of pawl 98 are disengaged from the teeth 90a of cog wheel 90 and teeth 96a on bearing surface 96. In this unlocked position, the luminaire housing 2 can rotate relative to the fitter mechanism 80 and the position of the luminaire housing 2 can be adjusted. In the unlocked position, the teeth on the cog wheel 90 can slide or ratchet over the teeth 96a, 98a as the housing 2 is rotated. Suitable structure may be provided on the inside of the base 4 and cover 6 to guide the pawl 98 as it moves between the locked and unlocked positions.

[0043] The cover 6 includes an opening or aperture 110 that allows access to the head of threaded member 106 even when the cover 6 is in the closed position. The threaded member 106 does not engage the cover 6 and opening 110 is wide enough to allow the head of threaded member 106 to pass through without engaging the cover 6. Any suitable tool may be inserted through opening 110 and engage a mating geometry 106a on the threaded member 106 to allow the threaded member to be loosened and tightened such as a socket wrench, Phillips head screwdriver, regular screw driver, or the like.

[0044] To adjust the angle of tilt of luminaire 1, both of the threaded adjustment members 106 are loosened. Specifically, a tool is inserted through openings 110 and is engaged with the threaded members 106. The tool is turned to unscrew the threaded members 106 from holes 108 thereby loosening the teeth 96a and 98a from the teeth 90a on the cog wheels 90. Once loosened, the luminaire housing 2 may be pivoted on hub 84 relative to connection member 82 to thereby increase or decrease the tilt angle of the luminaire 1 about axis B-B as shown in FIG. 17. As the luminaire 1 is rotated relative to the hub 84 the teeth on pawl 98 can ride over the teeth on cog wheel 90 in either rotational direction such that the end of the luminaire remote from the fitter mechanism 80 may be raised and/or lowered. Once the luminaire housing 2 is set to the desired tilt angle, the threaded members 106 are tightened into unthreaded holes 108 to force the teeth 90a on the cog wheels 90 into tight engagement with the teeth 96a on bearing surfaces 96 and the teeth 98a on the pawl 98 to thereby lock the luminaire housing 2 in the desired angular position.

[0045] To assist the installer in the positioning of the luminaire housing 2, the hub

84 may be provided with an angle indicator 112. The angle indicator 112 comprises a first engagement member 114 that may comprise a raised ridge centered on the axis of rotation B-B that includes a series of notches 114a with each notch located at a specific angular orientation of the housing 2. A mating engagement member 117 such as a stationary flexible finger 117 is formed on one of the cover 6 and base 4 that engages the raised ridge 114 in a ratcheting manner to identify the angle of orientation of the luminaire housing 2. Indicia 115 that indicate the angle of orientation of luminaire housing 2 may be provided to provide a visual indication of the angle of orientation of the luminaire housing 2 for the installer. The fitter mechanism 80 as described herein can adjust the luminaire between approximately -20 ⁰ up to approximately +110 ⁰ relative to the connection member 82 as shown in FIG. 17. In other embodiments, the angle of inclination may be even in both directions such as ±20°. Typically, the angle of the luminaire housing 2 is adjusted to the orient the housing 2 in a horizontal position, although the luminaire housing 2 may be adjusted to have other orientations.

[0046] The unthreaded second bore 104 on pawl 98 receives a self-threading locking member 120 that functions to lock the cover 6 in the closed position. The threaded locking member 120 extends through an opening 122 formed in the cover 6 and threadably engages bore 104. The head 120a of the locking member 120 has a larger diameter than the opening 122 such that when the locking member 120 is tightened in the locked position the head 104a engages the outside surface of the cover 6 to hold the cover 6 in the locked position. The locking members 120 may be loosened and removed from bores 104 to allow the cover to be opened.

[0047] The locking members 120 and the adjustment members 106 are disposed in close proximity to one another with the heads of these members facing in the same direction. As a result, an installer can easily access both members 106 and 120 from the same side of the luminaire housing 2 and from the same direction of handling to thereby greatly facilitate the installation and maintenance of the luminaire 1. The angle of inclination of the housing may be adjusted without opening the cover 6 and the cover 6 may be opened without affecting the angle of inclination.
