Description

A Pathway Lighting Unit The present invention relates to a pathway lighting unit for a walled pathway.

In certain circumstances a pathway may provide the most direct or readily available route for laying power cables, signaling cables, telecommunication cables, water pipes, gas pipes etc. from one location to another A contractor laying cables, pipes etc. can save time and cost by using the land access and existing infrastructure of the pathway. Another advantage of a pathway is that it provides easy access to contractor's personnel and their equipment. The pathway may be a pedestrian pathway, a vehicle pathway such as a road, or a bridge or tunnel having a pathway.

All such pathways may provide good access for laying cables, pipes etc. Some pathways have one or more side walls to which means for supporting cables or pipes may be mounted. This avoids the trouble of digging up the ground to lay the cables or pipes and provides relatively easy access if maintenance is needed in the future. Wall-mounted cable supports are commonly seen around roads and railways, for example, as they provide an attractive solution. However, over time an increasing numbers of cable supports can obstruct each other and, in extreme cases, dominate use of the side wall leaving little available space for other uses.

This problem is difficult to solve if the cables, pipes etc. located in the cable supports continue to serve a useful purpose and cannot be relocated to make space available without major upheaval to the networks they serve.

Accordingly, in a first aspect of the present invention, there is provided a pathway lighting support for attachment to a side wall of a walled pathway, wherein the support is elongate and the support comprises: a bracket for fixing the support to the side wail of the wailed pathway; a means for supporting at least one cable or pipe along an axis of elongation of the support; and a means for supporting a lighting module. This may improve pathway infrastructure by providing illumination and in doing so making the pathway safer. As the support is elongate, lighting and support for the cables or pipes may be spread over a long strip of pathway. Advantageously, the pathway lighting support can be retrofitted to the side wall of the pathway without relocating the existing cables and pipes or disrupting to the networks they serve.

This saves time and cost. Advantageously, the pathway lighting support may provide illumination whilst providing readily available spare capacity to support new cables or pipes which may be needed in the future.

Preferably, the means for supporting the at least one cable or pipe comprises at least one shelf. The cables may be supported evenly along their length to avoid sagging.

Preferably, the at least one shelf comprises a plurality of shelves. Different cables and/or pipes may be separated according to their shape, size, use and/or ownership.

Preferably, the means for supporting the at least one cable or pipe comprises a conduit and wherein the at least one shelf divides the conduit into at least one discrete channel extending along the axis of elongation of the support. The contents of the conduit are shielded within the confines of the conduit.

Preferably, conduit is openable along the axis of elongation of the support. This provides internal access all along one side of the conduit. Such access is easier and makes more efficient use of space inside the conduit than access gained by threading the cables or pipes through one end of the conduit.

Preferably, the at least one shelf is fixed to the support and wherein a side of the conduit is detachably fixed to the support. The channels inside the conduit are exposed when the side of the conduit is removed. Cables or pipes can be laid directly upon the at least one shelf.

Preferably, the means for supporting at least one cable or pipe is ventilated. This helps to prevent accumulation of heat or moisture within the support.

Preferably, the support comprises a roof located on top of the support in normal use.

The roof helps to shield the contents of the support from tampering and from inclement weather.

A side wall may be to keep pedestrians and/or vehicles within the confines of the pathway. The pathway may be elevated, like, for example, a bridge or a path on a high slope or in a building, in which case the side walls provide security to pathway Lisers. The pathway may be adjacent to private property in which case the side walls are to inhibit unauthorized entry by pathway users. If, for example, the walled pathway is a bridge over a railway or a motorway, the sidewalls provide security to both the pathway user and the railway or road user. In this case, the side walls are particularly high and can exceed two metres.

Side walls cause pathways to be shady or dimly lit around the pathway's deck and particularly in corners between the side wall and deck. This is particularly so with the high-sided walled pathways mentioned above. Attachment of pathway lighting units to the side walls illuminates the deck and helps facilitate use by pedestrians or by vehicles. Ideally, the pathway lighting units are attached low enough for bright uniform lighting across the deck. However, attachments to the lower reaches of the side wall may serve as a foothold for scaling the side wall. The walled pathway's security may be compromised unless the side wall is raised. This increases the cost of pathway improvement and has the counter-productive effect of making the pathway shady.

Preferably, the roof is configured to inhibit the support from acting as a foothold.

This inhibits use of the pathway lighting support to scale the side wall of a walled pathway. Advantageously, the pathway lighting support may be attached at any height of the side wall so that it may be located for optimum brightness and uniformity of lighting across the deck.

The roof configuration may have one or more of the following features, alone or in combination. The roof is shaped to inhibit gripping of materials used in soles of shoes. In particular, the rooftop surface is designed to have a co-efficient of friction low enough to cause a rubber sole to slip if someone attempts to stand on the pathway lighting support A reduced co-efficient of friction may be achieved by anti-climb coating or by vertical crenulations applied to the roof top surface, for example.

The roof may comprise a smooth top surface. A smooth surface is easy to manufacture. A smooth surface has a reduced co-efficient of friction, especially in wet conditions, when it is reduced further. The roof may be curved or flat.

Preferably, the roof comprises a substantially flat top surface inclined with regard to the side wall of the walled pathway by an angle of inclination of 45 degrees or less.

An angle of inclination of 45 degrees, or less, inhibits gripping of a shoe sole and makes it uncomfortable to even attempt to gain a foothold upon the support. More preferably, the angle of inclination is 35 degrees or less. This makes the ioof more slippery and more uncomfortable to attempt a foothold upon the support. Still more preferably, the angle of inclination is 25 degrees or less. This further reduces the total contact area in a horizontal plane, and, in doing so makes the roof even more slippery, without making the pathway lighting support too tall.

Preferably, the roof is detachably fixed to the bracket. This enables assembly, and disassembly, of the support to facilitate easier maintenance.

Preferably, the roof is saddled over the bracket. The bracket may be fixed to the side wall initially. Next, the roof is saddled over the bracket before being correctly aligned and fastened thereto. This arrangement facilitates easier assembly of the support.

Preferably, the means for supporting a lighting module comprises a lighting module receiving bay in the support. The lighting module receiving bay may protect the lighting module from the external elements and from interference.

Preferably, a portion of the lighting module receiving bay is formed by a skirt wall depending from the roof. Removal of the roof, leaving the bracket in situ, provides direct access to components located within the lighting module receiving bay to facilitate easier maintenance.

Preferably, the skirt wall comprises a rounded edge arranged along a corner of the lighting module receiving bay. The rounded edge helps to conceal components located within the lighting module receiving bay.

Preferably, the support comprises a duct to provide communication between the lighting module receiving bay and exterior of the support. An external power supply may be connected, via the duct, to components located within the lighting module receiving bay.

Preferably, the duct comprises a portion of the lighting module receiving bay shielded by a detachable cover plate. The duct may occupy otherwise empty parts of the lighting module receiving bay thereby putting such space to good use.

The support may be provided with or without lighting module. Preferably, the support comprises a lighting module detachably fixed to the means for supporting a lighting module. A defective lighting module may be renewed without needing to renew the support.

The lighting module may comprise a light source such a one or more filament lamps or neon lights. Light-emitting diodes are a viable alternative light source in many applications and may be used in place of filament lamps or neon lights. For the sake of brevity the conventional term "LED" shall be used to describe a light-emitting diode hereon. Preferably, the lighting module comprises a LED lighting module having at least one LED and a LED driver circuit for supplying electric power to the at least one LED. Advantageously, LEDs have lower energy consumption, longer lifespan and improved reliability.

In a second aspect of the present invention, there is provided a walled pathway comprising at least one side wall with the pathway lighting support of the first aspect fixed thereto. The walled pathway benefits from the advantages provided by the pathway lighting support.

Preferably, the walled pathway is an elevated walled pathway. Additional security measures, such as catch netting on the outside of the elevated pathway, may not be needed.

Preferably, the elevated walled pathway comprises a bridge over a railway.

Railways typically have many bridges in need of pathway lighting. The pathway lighting support may be installed without modification to the side walls thereby saving cost.

In a third aspect of the present invention, there is provided a method of fixing a pathway lighting support to a walled pathway, wherein the method comprises the steps of: (a) preparing the side wall for the support; (b) fixing the bracket of the support to the side wall; and (c) supporting the at least one cable or pipe along the support. The pathway lighting support is fixed to the side wall of the walled pathway in an efficient manner.

Preferably, the method further comprises the step of: (d) arranging the roof upon the support.

Preferably, the method further comprises the steps of: (e) fixing the lighting module to the means for supporting a lighting module; and (f) connecting an external power supply to the lighting module.

These and other features and advantages of the present invention will be better understood from the following detailed description, which is given by way of example and with reference to the accompanying drawings, in which: Figure 1 shows a perspective view of a bridge over a railway; Figure 2 shows a vertical cross-section Il-Il through a pathway of the bridge of Figure 1; Figure 3 shows a perspective view of a first embodiment of a pathway lighting unit; Figure 4 shows an exploded perspective view of the lighting unit of Figure 3; Figure 5 shows a side elevation view of the lighting unit of Figure 3; Figure 6 shows a bottom view of the lighting unit of Figure 3; Figure 7 shows a cross-section VIl-VIl through the lighting unit of Figure 3 fixed to a side wall; Figure 8 shows a cross-section VIll-VIll through the lighting unit of Figure 3 fixed to a side wall; Figure 9 shows the cross-section VIll-VIll of Figure 8 without a cover plate in the lighting unit; Figure 10 shows a portion of a perspective view of a second embodiment of a pathway lighting unit with a conduit to support cable, pipes etc.; Figure 11 shows a side elevation view of the lighting unit of Figure 10; Figure 12 shows a bottom view of the lighting unit of Figure 10; and Figure 13 shows a cross-section Xl-Xl through the lighting unit of Figure 10 when fixed to a side wall.

Referring to Figure 1, there is shown a bridge 10 over a railway 100. The bridge is for pedestrians. The bridge has a pair of stairways 12, 14. One stairway 12 leads to a first side a walled pathway 16 which spans the railway and the other stairway 14 leads to a second opposite side of the walled pathway. The pathway 16 and stairways 12, 14 are each bounded on both sides by side walls, one of which is shown equipped with a pathway lighting unit 200. Side walls on one side, or both sides, of the pathway and/or stairways may be equipped with a respective lighting unit.

Referring to Figure 2, the walled pathway 16 comprises a floor 18 spanning two upright side walls 20a, 2Db wherein upright is intended to mean vertical or practically vertical. The floor is coaled with a deck 22 to support the passage of pedestrians over the pathway. A width X of the deck is sufficient to allow passage of at least one pedestrian. A height Y of each side wall is sufficient to inhibit an adult from jumping over. The inner surface 21a, 21b of each respective side wall 20a, 20b is flat to inhibit the side wall from providing a foothold that could enable scaling of the side wall.

To facilitate pedestrian access, a lighting unit 200 is fixed to the inner surface 21a, 21b of each side wall 20a, 20b. The lighting units project light L downward toward the deck 22. The height of the lighting units above the deck is selected to ensure that the beam of light diverging from lighting units covers the deck uniformly.

Referring to Figures 3 to 9, there is shown a first embodiment of the lighting unit 200 in more detail. The lighting unit is elongate, although shorter versions are feasible without departing from the scope of the invention. Alternatively, the lighting unit may be curved for use with a curved wall, for example. The lighting unit comprises lighting support 202 and a lighting module 204 supported in a lighting module receiving bay 206 recessed within the support. The support comprises a bracket 208 for fixing the support to the side wall of the pathway and a roof 210 located on top of the support. Both the bracket and the roof are formed of flat metal sheet pre-coated with anti-corrosion material. Alternatively, the bracket and the roof could be formed of extruded metal pro-coated with anti-corrosion material.

Referring in particular to Figures 8 and 9, the bracket 208 is has a generally L-shaped cross-sectional profile. The bracket's upright limb comprises a fiat back section 208a and a shoulder section 208b located in a plane proud of the back section. The back section 208a is perforated by holes 2008a through which pass fasteners 212 for fixing the support 202 to a side wall 20b with the back section generally flush against the inner surface 21b. A pocket 214 is defined by the space between the shoulder section and the side wall's inner surface. The bracket's horizontal limb comprises a base section 208c and a side section 208d depending from the base section.

The roof 210 has an inverted generally V-shaped cross-sectional profile saddled over the bracket 208. The roof comprises a flat top surface 210a inclined with regard to the inner surface 21 b of the side wall 20b by an angle of inclination a. The top surface is smooth. The angle of inclination a is 25 degrees. The roof comprises a flap 210b depending from an apex 210e of the top surface 210a. The roof comprises a skid wall 210c depending from a lower end of the top surface opposite to the apex. The roof is detachably fixed to the bracket 208 by seating the flap in the pocket 214. The skirt wall is perforated by holes 2010c. The bracket's side section 208d is perforated by holes 2008d aligned with the skirt wall's holes. Fasteners 216 pass through the holes 20USd and 2010c to fix the roof to the bracket. The fasteners 216 may be rivets or anti-tamper screws or bolts.

The lowermost portion of the skirt wall 21 Dc overhangs the side section 208d of the bracket 208 and terminates with a rounded edge 210d arranged at a corner of the lighting module receiving bay 206. The lighting module receiving bay 206 is defined by the space between the base section 208c and side section 208d of the bracket 208, the side wall's inner surface 21b and the overhanging portion of the skirt wall 210c and rounded edge 210d. The lighting module receiving bay extends between a pair of end caps 218a, 218b connected to opposite extreme ends of the support 202.

Referring in particular to flgures 4 and 7, the lighting module 204 comprises an elongate body 220 with a rectangular cross-sectional profile shaped to fit within the lighting module receiving bay 206. The rectangular cross-sectional profile of the body is 23mm x 28mm. The lighting module is located in the lighting module receiving bay. The lighting module is detachably fixed to the support 202 by fasteners (not shown). The lighting module comprises an array of white LEDs 222, a LED driver circuit 224 for supplying electric power to the LEDs and a lens 230. The array of LEDs is arranged in a straight line to project light L downward through the lens and toward the deck 22. The lens projects an asymmetric beam of light L sweeping from the side wall's inner surface 21 b towards the middle of the pathway 16 and beyond. The LED driver circuit is connected to an external power supply providing 24 Volts to 48 Volts, alternating current or direct current. The LED driver circuit converts the external power supply into an electric supply compatible with the LED5 voltage and current requirements. The LED driver circuit is also controllable for dimming the light output from the LEDs.

Referring in particular to Figures 4, 6 and 8, the support 202 comprises at least one cover plate 226 shaped to fit within a portion, or individual portions, of the lighting module receiving bay 206 unoccupied by the lighting module 204. The cover plate is formed of flat metal sheet pre-coated with anti-corrosion material. Alternatively, the cover plate could be formed of extruded metal pre-coated with anti-corrosion material. The cover plate may be detachably fixed to the support by friction fit, clip-fit or by fasteners. The cover plate shields the ends of the lighting module from external elements and shields fasteners fixing the lighting module to the support.

The cover plate and the lighting module receiving bay define a duct 228 along the lighting unit 200. Electric cables (not shown) connecting the external power supply to the LED driver circuit 224 pass via the duct.

Referring to Figures 5 and 7, the lighting unit 200 has a length A measured between extreme ends of the support 202 which may vary according to customer specifications, provided it may accommodate one or more lighting modules 204 having a nominal length of 300mm, 600mm, 900mm or 1200mm and associated equipment. The lighting unit has a depth B of 35 mm between the side wall's inner surface 21b and the roofs skirt wall 210c.

The lighting unit has a height D of 80mm between the roofs apex 210e and rounded edge 210d. -10-

Referring to Figures 1 to 9, the support 202 is fixed to the inner surface 21b of the side wall 20b of the bridge 10 in stages. The side wall is prepared so that the support, and, in particular, the flat back section 208a of the bracket 208 may be fixed against the side wall's inner surface. The roof 210 is arranged so that the gap C and the angle of inclination cx are both small enough to inhibit the support 202 from acting as a foothold that could enable scaling of the side wall of the bridge. The bracket is fixed to the side wall by fasteners 212. The roof is saddled over the bracket and fixed thereto by fasteners 216. The lighting module 204 is located in the lighting module receiving bay 206 and fixed to the support by fasteners. One or more lighting modules may be located in the lighting module receiving bay. The LED driver circuit 224 of the, or each, lighting module is connected to the external power supply by electric cables passing via the duct 228. The cover plate 226 is located in a portion, or individual portions, of the lighting module receiving bay unoccupied by the lighting module 204 and fixed to the support by fasteners.

Referring to Figures 10 to 13, there is shown a second embodiment of the lighting unit 300 which is taller in normal use than the first embodiment of the lighting unit 200. The lighting unit 300 is taller to provide internal space for a conduit 340 to accommodate and support power cables, signaling cables, telecommunication cables, water pipes, gas pipes etc. which may extend along the lighting unit and along the pathway 16. In this second embodiment, structural elements which are similar to those previously discussed are designated by a corresponding reference numeral starting with "3" instead of"2".

The lighting unit 300 is elongate and generally straight, although it may be curved for use with a curved wall, for example. The lighting unit comprises lighting support 302 and a lighting module 304 supported in a lighting module receiving bay 306 recessed within the support. The support comprises a bracket 308 for fixing the support to the side wall of the pathway and a roof 310 located on top of the support.

The conduit 340 is accommodated by internal space between the bracket and the roof The bracket, the conduit and the roof are formed of flat metal sheet pre-coated with anti-corrosion material. Alternatively, the bracket, the conduit and the roof could be formed of extruded metal and pre-coated with anti-corrosion material.

Referring in particular to Figures 10 and 13, the conduit 340 is elongate with an axis of elongation Fl and extends along the length of the support 302. The conduit has a generally rectangular cross-sectional profile normal to axis Fl. The conduit is arranged with its long sides generally upright in normal use and its shod side generally horizontal in normal use.

The sides of the conduit are formed by a pair of elongate and opposing C-shaped sections: an outer section 34Db with its shod sides fitted over shod sides of an inner section 340a to connect the inner and outer sections by friction fit. Optionally, the inner and outer sections may be connected by other means such as interference fit, spring-loaded detents, fasteners or a lock. The inner section is connected to a pair of shelves: an upper shelf 340c and a middle shelf 340d, both of which are generally horizontal in normal use. The shelves extend along the length of the conduit and between the inner and outer sections. The shelves divide the conduit into three discrete channels. These three channels are an upper channel 3040c supported by the upper shelf, a middle channel 3040d suppoded by the middle shelf and a lower channel 3040aa suppoded by the lower shod side 340aa of the inner channel. The upper channel 3040c and lower channel 3040aa have approximately the same cross-sectional area of 2300mm2. The middle channel 3040d has approximately the same cross-sectional area as the upper channel 3040c and lower channel 3040aa combined which is 4600mm2. The cross-sectional area of the upper, middle and lower channels may vary according to customer specifications.

The long side of the inner section 340a abuts the bracket 308. The long side of the inner section 340a is perforated by holes 3040e aligned with corresponding holes in the bracket 308, as is explained in more detail below. There exists a gap E of about 5mm between the long side of the outer section 340b and the roof 310. The gap F may vary according to customer specifications. The long side of the outer section is perforated by holes 3040f which may provide ventilation for the interior of the conduit. When the roof is removed from the bracket, the outer section can be pulled away from the inner section to open one long side of the conduit along its axis of elongation. The upper shelf 340c and the middle shelf 340d remain connected to the -12-inner section when the outer section is removed therefrom. This provides access to the interior of the conduit to facilitate location and/or removal of cables, pipes etc. The bracket 308 is has a generally [-shaped cross-sectional profile. The bracket's upright limb comprises a flat back section 308a and a shoulder section 308b located in a plane proud of the back section. The back section 308a is perforated by holes 3008a which are aligned with the holes 3040e in the inner section 340a Fasteners 312 pass through the inner section 3040e and bracket holes 3008a to fix the support 302 to a side wall 2Db with the back section 308a generally flush against the inner surface 21b. In doing so, the fasteners 312 fix the conduit 340 to the bracket 308.

The fasteners 312 have counter-sunk heads to minimize obstruction to the contents of the conduit. A pocket 314 is defined by the space between the shoulder section 308b and the side wall's inner surface 21b. The bracket's horizontal limb comprises a base section 308c and a side section 3USd depending from the base section.

The roof 310 has an inverted generally V-shaped cross-sectional profile saddled over the bracket 308. The roof comprises a flat top surface 310a inclined with regard to the inner surface 21 b of the side wall 2Db by an angle of inclination The top surface is smooth. The angle of inclination 13 is 35 degrees. The roof comprises a flap 310b depending from an apex 310e of the top surface 310a. The roof comprises a skid wall 310c depending from a lower end of the top surface opposite to the apex. The roof is detachably fixed to the bracket 308 by seating the flap in the pocket 314. The skirt wall is perforated by holes 3010c. The bracket's side section 308d is perforated by holes 3008d aligned with the skirt wall's holes 3010c.

Fasteners 316 pass through the holes 3008d and 3010c to fix the roof to the bracket. The fasteners 316 may be rivets or anti-tamper screws or bolts.

The lowermost portion of the skirt wall 310c overhangs the side section 308d of the bracket 308 and terminates with a rounded edge 310d arranged at a corner of the lighting module receiving bay 306. The lighting module receiving bay 306 is defined by the space between the base section 308c and side section 308d of the bracket 308, the side wall's inner surface 21b and the overhanging portion of the skirt wall 310c and rounded edge 310d. The lighting module receiving bay extends between -13-opposite extreme ends of the support 302. End caps (not shown) may be connected to the ends of the support 302, if necessary. Normally, one or both ends of the support 302 will be connected to another adjacent support 302 to provide continuity of support for the contents of the conduit 340 along the pathway 16.

Referring in particular to Figure 10, the lighting module 304 comprises an elongate body 320 with a rectangular cross-sectional profile which fits within the lighting module receiving bay 306. The rectangular cross-sectional profile of the body is 23mm x 28mm. The lighting module is located in the lighting module receiving bay.

The lighting module is detachably fixed to the support 302 by fasteners 342. The lighting module comprises an array of white LEDs 322, a LED driver circuit 324 for supplying electric power to the LEDs and a lens 330. The array of LEDs is arranged in a straight line to project light L downward through the lens and toward the deck 22. The lens projects an asymmetric beam of light L sweeping from the side wall's inner surface 21b towards the middle of the pathway 16 and beyond. The LED driver circuit is connected to an external power supply providing 24 Volts to 48 Volts, alternating current or direct current. The LED driver circuit converts the external power supply into an electric supply compatible with the LEDs voltage and current requirements. The LED driver circuit is also controllable for dimming the light output from the LED5.

Referring in particular to Figures 10, 12 and 13, the support 302 comprises a cover plate 344 around each lighting module 304. Each cover plate has an aperture 344a in a lower face 344b through which protrudes the lens 330 of an adjacent lighting module. Each cover plate is shaped to fit within a portion of the lighting module receiving bay 306. The cover plate is formed of flat metal sheet pre-coated with anti-corrosion material. Alternatively, the cover plate could be formed of extruded metal and pre-cooted with anti-corrosion material. The cover plate is detachably fixed to the support by fasteners 346. The cover plate shields all but the lens of the lighting module from external elements and shields the fasteners 342 fixing the lighting module to the support. The cover plate and the lighting module receiving bay define a duct 328 along the lighting unit 300. Electric power supply cables (not shown) -14-connecting the external power supply to the LED driver circuit 324 pass via the duct.

The fasteners 346 may be rivets or anti-tamper screws or bolts.

Referring to Figures 11 to 13, the lighting unit 300 has a length F of 2115mm measured along an axis of elongation Fl of the support 302 to accommodate four lighting modules 304 each having a length of 600mm plus their associated equipment. Length F may vary according to customer specification, provided the lighting unit 300 may accommodate one or more lighting modules 304 having a nominal length of 300mm, 600mm, 900mm or 1200mm and associated equipment.
