     BACKGROUND OF THE INVENTION 
     In some instances, lighting fixtures are mounted to poles by a bracket. Each lighting fixture has its own particular bracket that must be used to mount the lighting fixture to the pole. This results in a large inventory in brackets which is expensive to maintain. 
     In addition to light, lighting sources and the electrical components used to drive the lighting sources generate heat during operation. This heat must be managed to allow for proper operation of the lighting fixture and maximum life of the lighting source and the electrical components. 
     SUMMARY OF THE INVENTION 
     Some embodiments of the invention provide a lighting fixture that can include a pole, a lighting source, and a driver. The pole can be hollow and has a first end and a second end opposite the first end. The lighting source can be mounted to the first end of the pole. The driver can be mounted within the pole at the second end. Electrical wiring can be provided within the pole extending between the lighting source and the driver. 
     Other embodiments of the invention provide a pole lighting fixture that can include a lighting source and a driver. The driver can be mounted remotely from the lighting source within the pole lighting fixture. 
     Some embodiments of the invention provide a lighting system for installation on a hollow pole with a top end and a bottom end. The lighting system can include a lighting source, a driver, and electrical wiring. The lighting source can be mounted to the top end of the hollow pole. The driver can be mounted to the bottom of the pole. The electrical wiring can extend from the driver, through the pole, to the lighting source.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     While the disclosure may be susceptible to embodiment in different forms, there is shown in the drawings, and herein will be described in detail, specific embodiments with the understanding that the present disclosure is to be considered an exemplification of the principles of the disclosure, and is not intended to limit the disclosure to that as illustrated and described herein. Therefore, unless otherwise noted, features disclosed herein may be combined together to form additional combinations that were not otherwise shown for purposes of brevity. It will be further appreciated that in some embodiments, one or more elements illustrated by way of example in a drawing(s) may be eliminated and/or substituted with alternative embodiments within the scope of the disclosure. 
     A universal mounting system  20 ,  20   a ,  20   b ,  20   c  is provided for mounting a lighting fixture  22 , particularly an outdoor lighting fixture, to an any pole  24  that extends from the ground. The pole  24  has a lower end which is attached to the ground, an open upper end  26  and a passageway  25  that runs through the pole from its lower end to its upper end. The pole  24  is usually square but may be cylindrical, but may take other forms, such as having a square or rectangular cross-section. The universal mounting system  20 ,  20   a ,  20   b ,  20   c  is configured for applications such as a parking lot lighting, auto dealerships, display (e.g. building-elevation, billboard, etc.) application, etc. When the universal mounting system  20 ,  20   a ,  20   b ,  20   c  is mounted to an existing pole  24 , no modification to the existing infrastructure is necessary other than to occasionally drill a pair of aligned holes  28   a ,  28   b  proximate to the top end of the pole  24 , and attaching the universal mounting system  20 ,  20   a ,  20   b ,  20   c  and lighting fixture  22  to the pole  24  as described herein. Therefore, the universal mounting system  20 ,  20   a ,  20   b ,  20   c  is easily used to retrofit any existing pole  24 . 
     The lighting fixture  22  includes a cover  30  and a pan  32  that mates together to form an internal cavity therewithin. The cover and pan  30 ,  32  form a housing which surrounds one or more lighting sources  34 , such as LEDs, and includes a lens  36  (e.g., a plastic sheet, a glass sheet, etc.) that allows light from the one or more lighting sources  34  to shine downwardly from the lighting fixture  22 . Other electronics may be mounted within the internal cavity formed by the cover and pan  30 ,  32  as discussed herein. 
     As shown in  FIGS. 1-7 , the cover  30  has an upper wall  38  and a side wall  40  which depends downwardly therefrom to form an open-ended box-like structure. As shown, the upper wall  38  is rectangular and the side wall  40  is formed of four portions which are joined together at their ends. The cover  30  may take other shapes. The side wall  40  includes a plurality of spaced apart, small diameter vias  41  to allow air to pass out of the lighting fixture  22 . The vias  41  are small enough to allow air to pass therethrough, but not allow contaminants into the lighting fixture  22 . The vias  41  may have a diameter which ranges in size from 0.040″ to 0.187″. 
     The pan  32  includes a lower wall  42  and a side wall  44  which extends upwardly therefrom to form an open ended box-like structure. As shown, the lower wall  42  is rectangular and the side wall  44  is formed of four portions which are joined together at their ends. The pan  32  may take other shapes. The lower wall  42  has a plurality of spaced apart apertures  46 ,  48 ,  50  therethrough. As shown, three apertures  46 ,  48 ,  50  are provided, however, more or fewer than three may be provided. As shown, aperture  48  is centrally located and surround by a wall section  52  of the lower wall  42 . As shown, the aperture  48  is rectangular, but other shapes may be provided. Lighting sources  34  are mounted in the first and third apertures  46 ,  50  in a manner to allow the light to shine downwardly. The shape and orientation of the cover  30  and pan  32  relative to the lighting sources  34  is configured to provide a full cut off such that light does not project above the plane of the cover  30 . The lighting fixture  22  is preferably “dark-sky” compliant or friendly. The aperture  48  is open such that the internal cavity formed by the cover  30  and pan  32  can be accessed. 
     As shown in  FIGS. 7A-7C , the cover  30  and pan  32  may include a “no-drip” edge to prevent water intrusion therein. Each side wall  44  of the pan  32  has a bend  45  formed at the upper edge thereof which seats under the upper wall  38  and the side wall  40  of the cover  30 . The bend  45  include a first leg  47  which angles inwardly into the cavity formed by the cover  30  and the pan  32  and a second leg  49  which is horizontal and is perpendicular to the side wall  44  if the side wall  44  is vertical. As such, the first leg  47  and the second leg  49  are angled relative to each other. The side wall  40  of the cover  30  extends along an outer surface of the legs  47 ,  49  such that the bend  45  is seated under the cover  30 . The upper wall  38  abuts against the second leg  49  of the bend  45 . If water falls onto the cover  30 , the bend  45  prevents the intrusion of water into the pan  30 . 
     The universal mounting system  20 ,  20   a ,  20   b ,  20   c  includes a bracket  54 ,  54   a ,  54   b ,  54   c  which is attached to the upper end  26  of the pole  24  as described herein, a mounting fastener  56  which extends through the bracket  54 ,  54   a ,  54   b ,  54   c  and an upper end portion  26   a  of the pole  24 , a nut  58  which attaches to the mounting fastener  56 , and a plurality of fasteners  60  for attaching the bracket  54 ,  54   a ,  54   b ,  54   c  to the wall section  52  of the lower wall  42  of the lighting fixture  22 . The component pieces of the universal mounting system  20 ,  20   a ,  20   b ,  20   c  may be formed of galvanized steel but may be any other metal (e.g., steel, aluminum), plastic, and/or composite material, or a combination thereof. 
     The bracket  54 ,  54   a ,  54   b ,  54   c  has an housing  62 ,  62   a ,  62   b ,  62   c  and a fastener mount  64 ,  64   a ,  64   b ,  64   c  as described herein.

       FIG. 7  shows a fourth embodiment of the bracket  54   c . In this embodiment, the housing  62  is identically formed to the housing  62  of the first embodiment and the specifics are not repeated. 
     In this embodiment, the fastener mount  64  may be formed integrally with the housing  62 , or formed separately and then fixedly attached to the housing  62 . In this embodiment, the fastener mount  64  is formed of a wall  100  which extends downwardly from the base wall  68  and surrounds the passageway(s)  74 . The wall  68  may be circular as shown, or may be rectangular, square, etc. The wall  100  has a pair of openings  102 ,  104  proximate to an end thereof, such that the openings  102 ,  104  are spaced from the lower surface of the base wall  68  by a predetermined distance. 
     In use, the lower surface of the base wall  68  seats on the upper end  26  of the pole  24  as previously described and the wall  100  extends into the passageway  25  of the pole  24  such that the passageway(s)  74  align with the passageway  25  through the pole  24 . The openings  102 ,  104  in the wall  100  align with the holes  28   a ,  28   b  in the pole  24 . The mounting fastener  54  is inserted through one hole  28   a  in the pole  24 , through the openings  102 ,  104  in the wall  100 , and through the other hole  28   b  in the pole  24 . The nut  58  is attached to the end of the mounting fastener  56  that extends outwardly from the pole  24 . This secures the bracket  54   c  to the pole  24 . The bracket  54   c  is then attached to the wall section  52  of the lower wall  42  of the lighting fixture  22  by the fasteners  60  that extend through the flange(s)  72  and into the wall section  52 . 
     The universal mounting system  20   c  can be easily removed from the pole  24  by reversing the order of assembly. The universal mounting system  20   c  can be easily removed from the lighting fixture  22  by removal of the fasteners  60  from the wall section  52  of the pan  32 . The universal mounting system  20   c  can then be used on another pole by reusing existing holes or drilling new holes through the pole. 
     As show, the fastener mount  64  can take a variety of shapes and forms and is not limited to the specific shapes shown herein. In addition, the fastener mount  64  may be formed of a single wall with a single aperture. 
     The universal mounting system  20 ,  20   a ,  20   b ,  20   c  can be used to mount a lighting fixture  22  to any pole  24  (which may be a pre-existing pole and the universal mounting system  20 ,  20   a ,  20   b ,  20   c  is used in a retrofit, or may be a new pole) by reusing existing holes or drilling new holes  28   a ,  28   b  into the upper end  26  of the pole  24 . The universal mounting system  20 ,  20   a ,  20   b ,  20   c  supports any type of lighting fixture  22  that has a surface to which the housing  62  can be attached. This eliminates the need for a variety of brackets as was done in the prior art. 
     A reinforcing channel (not shown) may be provided in the interior or exterior of the base wall  68 . The reinforcing channel is an elongated piece of metal having holes that match those of the base wall  68 . The reinforcing channel may be formed from steel, aluminum, plastic, or any other material that adds structural strength and rigidity to the universal mounting system  20 ,  20   a ,  20   b ,  20   c . Alternatively, the base wall  68  may have a thickened area to provide strength and rigidity to the universal mounting system  20 ,  20   a ,  20   b ,  20 . 
     The universal mounting system  20 ,  20   a ,  20   b ,  20   c  and/or the other metal structures of lighting fixture  22  may be powder coated or otherwise treated for durability of the metal. The universal mounting system  20 ,  20   a ,  20   b ,  20   c  is extremely robust and able to withstand environmental abuses of outdoor lighting fixtures  22 . The shape of the components of the universal mounting system  20 ,  20   a ,  20   b ,  20   c  are preferably such that the effective projected area (EPA) relative to strong wind loading is minimized, which correspondingly provides for universal application in all geographic regions, minimized wind loading parameters of the lighting fixture  22 . 
     While the mounting of the pole  26  on the universal mounting system  20 ,  20   a ,  20   b ,  20   c  is shown as offset to one side of the bracket  54 ,  54   a ,  54   b ,  54   c , the mounting of the pole  26  on the universal mounting system  20 ,  20   a ,  20   b ,  20   c  can be centered on the bracket  54 ,  54   a ,  54   b ,  54   c . This centering of the bracket  54 ,  54   a ,  54   b ,  54   c  on the pole  26  aids in weight distribution due to snow loading, and may aid in wind loading on the lighting fixture  22 .

     The driver plate  124  is formed of a base plate  132  having an aperture  134  therethrough, a pair of flanges  136  extending downwardly from opposite edges of the base plate  132 , a pair of flanges  138  extending upwardly from the base plate  132  along opposite edges of the base plate  132 , and a pair of flanges  142  extending upwardly from the base plate  132  along sides of the aperture  134 . The flanges  138 ,  140  are parallel to each other. 
     As shown, each bracket  126  is generally U-shaped with a base wall  142  and a pair of flanges  144  which extends from upper and lower edges of the base wall  142 . The bracket  142  may be a rectangle having a central passageway or may be solid. The upper flange  144   a  of each bracket  126  attaches to an underside of the base plate  132  of the driver plate  124 . The brackets  126  are spaced from the aperture  134  of the driver plate  124  such that the brackets  126  do not overlap the aperture  134 . As shown, two brackets  126  are provided. 
     The drivers  122  are attached to the underside of the base plate  132  of the driver plate  124 . As shown, four drivers  122  are provided, with a bracket  126  seating between each pair of drivers  122 . The brackets  126  separate the drivers  122  in each pair from each other. 
     A heat sink  128  seats against a lower end of each pair of drivers  122  is attached to the lower flange  144   b  of the bracket  126 . The heat sink  128  is contact with the drivers  122  to draw heat from the drivers  122  during operation of the lighting fixture  22 . The heat sink  128  may be formed of metal. As shown, each heat sink  128  is formed as a flat plate. The heat sink  128  may take over forms. 
     The driver mount  130  is formed of a base plate  146 , a pair of flanges  148  extending upwardly from the base plate  146  along opposite edges of the base plate  146 , and a rim  150  extending outwardly from the upper end of each flange  148 . The rims  150  are attached to the underside of the base plate  132  of the driver plate  124  on opposite sides of the aperture  134 . The base plate  146  abuts against the upper surface of the lower wall  689  of the pan  32 . The base plate  146  has passageway(s)  174 , spaced apart vias  175  and aperture(s)  176  that align with the passageway(s)  74 , vias  75  and aperture(s)  76  in the base plate  68  of the pan  32 . The vias  175  are formed in an array. Each via  175  has a small diameter and may range in size from 0.040″ to 0.187″ to correspond in size with the vias  75  in the pan  32 . Wires can be fed from the pole  24  through the passageways  74 ,  174  to connect to the lighting sources  34  and other electronics in the lighting fixture  22 . The arrays of vias  75 ,  175  allow air to flow from the pole  24  into the bracket  54 ′. The aperture  134  in the driver plate  124  allows the air to flow out of the bracket  54 ′ and into the internal cavity of lighting fixture  22  and then out of the vias  41 . The base plate  146  also has a hole  180  which aligns with hole  80  in the pan  32 . The hole  180  may be the same size as the door  81  or be provided in a door  181  which can be opened or closed to allow access to components within the bracket  54 ′. The camera or sensor  82  extends through holes  80 ,  180 . 
     As shown in  FIG. 13 , a space  182  is formed between the heat sinks  128  and the bracket  54 ′ as a result of the driver housing assembly  120  to aid in the dissipation of heat from the heat sinks  128 . The drivers  122  are electrically coupled to the lighting sources  34 , but are physically separated from the drivers  122 . 
     The driver plate  124 , brackets  126 , heat sinks  128 , and driver mount  130  may be formed of a cured synthetic polymerization composite which includes at least one polymerized resin and at least one additive which is disclosed in U.S. application Ser.

     Attention is now invited to  FIGS. 22-27  which show another embodiment of a lighting fixture  318 . It to be understood that the lighting fixture  318  can be used with any of the universal mounting system  20 ,  20   a ,  20   b ,  20   c  to mount the lighting fixture  322  to a pole. 
     The lighting fixture  22  includes the cover  30  and the pan  32  that mates together to form the internal cavity therewithin. The pan  32  is not shown in  FIGS. 22-27  for ease in showing the components of the lighting fixture  318 . The specifics of the cover  30  and the pan  32  are not repeated herein. 
     As shown, a pair of light assemblies  320  are mounted within each of the apertures  46 ,  50 . Each light assembly  320  includes a heat sink  322  attached to the upper wall  38  of the cover  30 , a first reflector  324  attached to the heat sink  322  and spans the length of the heat sink  322 , a second reflector  326  attached to the heat sink  322  and spans the length of the heat sink  322 , and a plurality of lighting sources  34 , such as LED lights, mounted on the heat sink  322  such that the light from the lighting sources  34  shines between the reflectors  322 ,  326 . As shown, a pair of light assemblies  320  are mounted in each aperture  46 ,  50 , but a single light assembly  320  or more than two light assemblies  320  can be mounted in each aperture  46 ,  50 . 
       FIGS. 22-27  show an alternate light assembly  320  which is the same as light assembly  220  except for the differences noted herein. In light assembly  320 , walls  238  and  240  are formed as part of the heat sink  322  instead of as part of the upper reflector  224 . As such, the upper reflector  324  includes wall  327  to connect the upper reflector  324  to the lower end of wall  240 . Upper reflector  324  also includes side walls  329  extending downwardly from wall  242 . The side walls  329  aid in directing the light from lighting sources  34  in the desired direction. The addition of the side wall  329  allows the fans  248  to be eliminated. 
       FIGS. 28-30  show a bi-directional light assembly  420 . One light assembly  420  is mounted in aperture  46  and another light assembly  420  is mounted in aperture  50 . 
     Each light assembly  220  includes a pair of heat sinks  322  which are attached to each other by a single upper reflector  424  and a bracket  425 , and pair of lower reflectors  426 . 
     The upper reflector  424  is formed of a first wall  460  which is horizontal, a second wall  462  extending outwardly from an end of the first wall  460  and at an angle relative to the first wall  460 , a third wall  464  extending outwardly from the opposite end of the first wall  460  and at an angle relative to the first wall  460 , side walls  466  extending downwardly from each end of the second wall  462 , and side walls  468  extending downwardly from each end of the third wall  464 . Each of walls  462 ,  464  may extend at the same angle from horizontal. The free end  462   a  of the second wall  462  abuts against, passes through, or is close proximity to the third wall  232  of the heat sink  322 . The free end  464   a  of the second wall  464  abuts against, passes through, or is close proximity to the third wall  232  of the other heat sink  322 . 
     The lower reflectors  426  differ from lower reflector  226  in that the wall  446  is perpendicular to wall  444 . As such, the lower reflectors  426  are formed of a first wall  444  which is horizontal, and a second wall  446  extending perpendicularly from an end of the first wall  444 . The first wall  444  is attached by suitable means to the lower surface of the fifth wall  236  of the heat sink  322 . The free end  446   a  of the second wall  446  abuts against or is close proximity to the third wall  232  of the heat sink  322 , but is spaced from the third wall  442  of the upper reflector  424 . 
     The bracket  425  is generally U-shaped and seats against the first wall  460  of the upper reflector  424  and engages the walls  240  of the heat sinks  322 . 
     The lighting sources  34  seat on the third wall  232  of the heat sink  322  and are positioned between the reflectors  424 ,  426 . The reflectors  424 ,  426  direct the light from the lighting sources  34  in the desired direction. 
     In some embodiments, the number of vias  75 ,  175  may be the same. In some embodiments, more vias  75  are provided in the mounting bracket  54 ′ than the number of vias  175  in the driver mount  130  so as to promote a chimney effect as the air flows through the universal mounting system  20 ,  20   a ,  20   b ,  20   c.    
     As shown in  FIG. 31 , a pole  24  is mounted on a mount  500  that extends into the ground  502 . The pole  24  is hollow and communicates with a conduit  504  mounted under the ground through which wiring for lighting is provided. The bottom  24   a  of the pole  24  is mounted such that there are gaps  506  between the pole  24  (shown exaggerated in  FIG. 31 ), and the mount  500  such that air flows into the hollow pole  24 . The air flows through the gaps  506  and through the conduit  504  into the universal mounting system  20 ,  20   a ,  20   b ,  20   c . The air can flow through the passageway  74 , or through the arrays of vias  75 ,  175  (as the passageways  74  will be filled with wiring), and into the bracket  54 ,  54 ′,  54   a ,  54   b ,  54   c . The air travels through the lighting fixture  22  and across the heat sinks  128 ,  222 ,  322  to aid in dissipating heat from the drivers  122 , the lighting sources  34  and any other electronics in the lighting fixture  22 . The air passes out of the lighting fixture  22  through the vias  41 . The vias  41  also provide for pressure relief within the lighting fixture  22  as a result of the air increasing in temperature within the light fixture  22  during operation. 
     As shown in  FIG. 32 , the pole  24  may have a light  600  which extends up at least part of the length of the pole  24 . Alternatively, or in addition to light  600 , the lighting fixture  22  may have a light  600 ′ on the cover  30  and/or the pan  32 . The light(s)  600 ,  600 ′ may change colors. The light  600  may extend the full length of the pole  24 , or part of the length of the pole  24 . The light  600 ′ may extend the full length of the cover  30  and/or pan  32 , or part of the length of the cover  30  and/or pan  32 . 
     As also shown in  FIG. 32 , the drivers  122  are mounted in the bottom  24   a  of the pole  24 . Since the drivers  122  are separated from the lighting sources  34 , this further minimizes the amount of heat generated by the lighting fixture  22 . Suitable wiring extends from the drivers  122 , through the pole, through the bracket  54 ,  54 ′,  54   a ,  54   b ,  54   c  to the lighting sources  34 . 
     As shown in  FIGS. 33-43 , a lighting fixture  720  is provided. In an embodiment, the lighting fixture  720  is used in a commercial and industrial settings, such as a warehouse. In another embodiment, the lighting fixture  720  is used in a residential setting. The lighting fixture  720  provides well distributed and uniform light for open areas. 
     An embodiment of the lighting fixture  720  is shown in  FIGS. 33-41 . Other embodiments of the lighting fixture ( 720 ′,  820 ,  920 ,  1020 ) are shown in  FIGS. 42 through 83 . 
     Attention is invited to the embodiment of the lighting fixture  720  shown in  FIGS. 33-41 . The lighting fixture  720  includes a driver housing assembly  722 , a heat sink  724  coupled to the driver housing assembly  722  by a mounting bracket  726 , one or more lighting sources  34  mounted to the heat sink  724 , and a lens  36  attached to the heat sink  724  for covering the one or more lighting sources  34 . The driver housing assembly  722  includes a driver  122  for controlling the illumination of the one or more lighting sources  34 . Such drivers  122  are known in the art. The drivers  122  include the electronics for activating/deactivating the lighting sources  32 . The driver  122  is substantially thermally separated from the one or more lighting sources  34  by the mounting bracket  726  in order to provide improved thermal management of the heat generating components, that is the driver  122  and the lighting sources  34 , of the lighting fixture  720 . The one or more lighting sources  34  may be LED lights or fluorescent lights or any other suitable lamps. 
     The driver housing assembly  722  includes a pan  732  which is covered by a cover  730  to form a box-like enclosure having a central cavity  740 . The driver  122  is mounted within the cavity  740  and may be mounted on the pan  732 . Other electronics and electrical components which may generate heat may be mounted within the internal cavity  740  formed by the driver housing assembly  722 . The embodiment described and shown herein is exemplary and the enclosure may take other forms. 
     The pan  732  is a generally U-shaped and is formed from an elongated, horizontal base wall  742  having opposite first and second side edges and opposite ends extending between the side edges, a first upstanding side wall  744  extending from the first side edge of the base wall  742 , and a second upstanding side wall  746  extending from the second side edge of the base wall  742 . A centerline  748  of the base wall  742  is provided between the ends. The walls  742 ,  744 ,  746  define a channel having an open-ended top. In an embodiment, the first and second upstanding side walls  744 ,  746  are vertical. 
     As shown in  FIG. 39 , the base wall  742  has a plurality of spaced apart small diameter vias  750  therethrough which extend from a top surface to a bottom surface thereof. The vias  750  are provided in an array. As shown, the vias  750  are provided in two rows, with the vias  750  being staggered from each other. The vias  750  may be provided on the centerline  748 , proximate to the centerline  748 , or offset from the centerline  748 . A continuous portion  752  of the base wall  742  may be provided, that is the base wall  742  is continuous in that it does not have vias  750 . The driver  122  may be mounted above the continuous portion  752  of the base wall  742 . The base wall  742  further has a cutout  754  provided in an end portion  755  at each end through which wiring (not shown) from the driver  122  extends. 
     The cover  730  has a base wall  756  having opposite first and second side edges and opposite ends extending between the side edges, a first depending side wall  758  extending from the first side edge of the base wall  756 , a second depending side wall  760  extending from the second side edge of the base wall  756 , and an end wall  762 ,  764  extending from the respective ends of the base wall  756 . Each end wall  762 ,  764  may be greater in height than the side walls  758 ,  760 . Each end wall  762 ,  764  has a plurality of spaced apart small diameter vias  766 ,  768  extending from an outer surface to an inner surface thereof. The vias  766 ,  768  are provided in arrays. As shown, the vias  766 ,  768  are provided in two rows, with the vias  766 ,  768  being staggered from each other. The vias  766 ,  768  may be provided proximate to a top end of each side wall  758 ,  760 . The base wall  756  may have a cutout therein into which an access panel  770  is mounted. The access panel  770  is suitably attached to the cover  730 . 
     The driver housing assembly  722  is formed by seating the cover  730  on top of the pan  732  such that the side walls  758 ,  760  of the cover  730  engage the side walls  744 ,  746  of the pan  732 . The side walls  758 ,  760  of the cover  730  may overlap the side walls  744 ,  746  of the pan  732 . The end walls  762 ,  764  of the cover  730  close the open ends of the pan  732 . The cover  730  and the pan  732  are suitably joined together, such as by fasteners. The vias  766 ,  768  allow for the passage of air from an interior of the driver housing assembly  722  to an exterior of the driver housing assembly  722 . Alternatively, the pan  732  may have four upstanding side walls and the cover  730  covers the open upper end of the pan  732 . 
     The heat sink  724  is formed from an elongated, generally U-shaped channel  772  having an end cap  774 ,  776  closing each end of the channel  772 . The channel  772  is formed from a horizontal base wall  778  having opposite first and second side edges and opposite ends extending between the side edges, a first depending side wall  780  extending from the first side edge of the base wall  778 , a first flange  782  extending inwardly from the lower end of the side wall  780 , a second depending side wall  784  depending from the second side edge of the base wall  778 , and a second flange  786  extending inwardly from the lower end of the side wall  784 . The walls  778 ,  780 ,  784  and flanges  782 ,  786  define a three-sided, open-ended channel. In an embodiment, the first and second side walls  780 ,  784  are angled outwardly relative to each other. In an embodiment, the heat sink  724  may be formed of a cured synthetic polymerization composite which includes at least one polymerized resin and at least one additive which is disclosed in U.S. application Ser. No. 14/854,906, filed on Sep. 15, 2015, the disclosure of which is incorporated by reference in its entirety. Alternatively, the heat sink  724  may be formed of a suitable metal, such as aluminum. Each end cap  774 ,  776  has a plurality of spaced apart small diameter vias  788 ,  790  extending from an outer surface to an inner surface thereof. The vias  788 ,  790  are provided in arrays. As shown, the vias  788 ,  790  are provided in two rows, with the vias  788 ,  790  being staggered from each other. The vias  788 ,  790  allow for the passage of air from an interior of the heat sink  724  to an exterior of the heat sink  724 . 
     The one or more lighting sources  34  mount within the heat sink channel  772  and shine downwardly. The heat sink  724  dissipates heat generated by the one or more lighting sources  34 . The one or more lighting sources  34  are covered by lens  36  (e.g., a plastic sheet, a glass sheet, etc.) attached to the channel  772  and that allows light from the one or more lighting sources  34  to shine downwardly from the lighting fixture  720 . The heat sink  724 , end caps  774 ,  776  and lens  36  form a housing for the lighting sources  34 . 
     The mounting brackets  726  connects the heat sink  724  to the driver housing assembly  722 . As shown, each mounting bracket  726  is formed of a horizontal mounting flange  792 , a first wall  794  extending from an outer end of the mounting flange  792  and which angles downwardly and outwardly relative to the mounting flange  792 , a second horizontal wall  796  which extends from the lower end of the first wall  794  and is parallel to the mounting flange  792 , and a third wall  798  which extends upwardly from the outer end of the second wall  796 . The third wall  798  may extend perpendicularly from the second wall  796 . The first, second and third walls  794 ,  796 ,  798  form a generally U-shaped recess  800 . The first wall  794  has an aperture  802  therethrough through which wiring extends. 
     At each end of the pan  732 , the upper surface of the mounting flange  792  of the mounting bracket  726  abuts against and is attached to the lower surface of the base wall  742  of the pan  732  by suitable means, such as fasteners. The end portion  755  where the cutout  754  is provided overhangs the recess  800  formed by the mounting bracket  726 . This allows wiring to pass through the cutout  754  and into the recess  800  and to allow for the passage of air between the driver housing assembly  722  and the mounting bracket  726 . At each end of the heat sink  724 , the lower surface of the second wall  796  of the mounting bracket  726  is attached to the upper surface of the base wall  778  of the heat sink  724  by suitable means, such as fasteners. As a result of this construction, the majority of any heat sink  724  which is mounted directly below the driver housing assembly  722  is separated from the driver housing assembly  722  by a gap  804 , see  FIG. 34 , formed by the height of the first wall  794  of the mounting bracket  726 . This gap  804  aids in minimizing heat transfer between the driver  122  and any other electrical components mounted in the cavity  740  and the one or more lighting sources  34  mounted on the heat sink  724 . 
     The end caps  774 ,  776  may be formed as part of a cover  806  which closes the recess  800  of the respective mounting bracket  726 . As shown, each cover  806  is formed of an upper horizontal wall  808 , a lower vertical wall  810  which depends from an outer end of the upper wall  808 , and side walls  810 ,  812  which extend downwardly at the side edges of the upper and lower walls  808 ,  810 . A lower surface of the upper wall  808  of the cover  806  abuts an upper surface of the mounting flange  792  of the mounting bracket  726 . The side walls  810 ,  812  of the cover  806  engage the side edges of the first, second and third walls  794 ,  796 ,  798  of the mounting bracket  726 . A portion of the lower wall  810  of the cover  806  forms the end caps  774 ,  776 . Therefore, as shown, the end caps  774 ,  776  of the heat sink  724  may be integrally formed as part of the covers  806 . Alternatively, the end caps  774 ,  776  may be formed separately from the covers  806  and attached to the heat sink  724 . The upper wall has a cutout into which the end of the driver housing assembly  722  seats. Respective covers  806  and mounting brackets  726  are suitably joined together, such as by fasteners or by tabs on one of the cover  806  and mounting bracket  726  extending in openings in the other of the cover  806  and the mounting bracket  726 . 
     The vias  750 ,  766 ,  768 ,  788 ,  790  may have a diameter of which range in size from 0.040″ to 0.187″, may be approximately 0.07″, and more particularly a diameter of 0.068″. The vias  750 ,  766 ,  768 ,  788 ,  790  are small to prevent the intrusion of dust and other contaminants into the driver housing assembly  722  and into the heat sink  724 , while allowing for air flow into the driver housing assembly  722  and into the heat sink  724 . The passage of air allows for convective heat transfer. The vias  750 ,  788 ,  790  through the end caps  774 ,  776  and through the base wall  742  of the driver housing assembly  722  allow cool air to enter into the heat sink  724  and into the driver housing assembly  722 . The vias  766 ,  768  through the end walls  762 ,  764  of the driver housing assembly  722  allows warm air to vent out of the lighting fixture  720 . 
     In the embodiments as shown in  FIGS. 42-83  at least two heat sinks are attached to the mounting bracket  726  and to the driver housing assembly  722  to form the lighting fixtures  720 ′ (five heat sinks),  820  (two heat sinks),  920  (three heat sinks), and  1020  (four heat sinks). 
       FIGS. 42 and 43  shows five heat sinks  724   a ,  724   b ,  724   c ,  724   d ,  724   e  attached to the mounting bracket  726 . Each heat sink  724   a ,  724   b ,  724   c ,  724   d ,  724   e  is identically formed to heat sink  724  and the specifics are not repeated herein. Each heat sink  724   a ,  724   b ,  724   c ,  724   d ,  724   e  is attached to the mounting bracket  726  in the same manner as described with respect to the first embodiment and the specifics are not repeated herein. Each heat sink  724   a ,  724   b ,  724   c ,  724   d ,  724   e  is attached to the end caps  774 ,  776  in the same manner as described with respect to the first embodiment and the specifics are not repeated herein. As shown in  FIG. 42 , the end caps  774 ,  776  are shown as part of the covers  806 , however, it is to be understood that individual end caps  774 ,  776  may be provided. The lighting fixture  720 ′ exemplifies an embodiment of the light fixture with more than one heat sink and the disclosure applies to the other embodiments with more than one heat sink, respectively. 
     If one or more heat sinks are provided, the heat sinks are spaced apart from each other along the length of the mounting bracket  726 . If multiple heat sinks are provided, a single aperture  802  or multiple apertures may be provided in the mounting bracket  726  to allow wiring to be run from the driver  122  in the driver housing assembly  722  to the lighting sources  34  mounted on each of the heat sinks. The number of heat sinks with associated lighting sources  34  are only limited by the length of the mounting bracket  726 . Therefore, the lighting fixture  720  is modular in that a desired number of heat sinks and associated lighting sources  34  can be provided. The heat sinks and associated lighting sources  34  may be evenly spaced along the mounting bracket  726 , or may be randomly spaced along the mounting bracket  726 . 
     The lighting fixture  720 ,  720 ′ is suspended from a ceiling or other structure such that the lighting sources  34  shine downwardly into the space to be illuminated. A mount  814 , see  FIG. 36 , is provided to attach the lighting fixture  720 ,  720 ′ to the ceiling or other structure. The mount  814  may attach to mounting holes  816  on the cover  806 . The mounting holes  816  may be provided through the mounting flange  792  of the mounting bracket  726 . 
     The driver housing assembly  722 , the mounting brackets  726 , the end caps  774 ,  776  and covers  806  may be formed of metal. The driver housing assembly  722 , the mounting brackets  726 , the end caps  774 ,  776  and covers  806  may be powder coated or otherwise treated for durability of the metal. The lighting fixture  720  is extremely robust.
