ILhTJMI~ATED CANOPY SYSTEM
~, .
.
Technical Field The present inventlon relates to lighted ;~ canopy and wall systems, particularly for gasoline service stations and other business establishments. The ~ascias of the canopies have transpar~nt displays which ' are illuminated from the rear for visibility and ., ~
aesthetics. Similarly, back-lit lightboxes are mounted on the buildings.
.
: Backqrou~d of The Invention , ~
Businesses with outdoor service areas, such as gasoline service s~ations, are taking steps today to improve the facilities and areas around them. The companies want to keep their places of business , attractive ~or custo~ers, keep the appearances on par with other businesses, and also make the facilities better illuminated and safer in non-daylight hours.
I ; Service stations in particular today are improYing the areas around their buildings and gasoline pumps by providing increased lighting and more aesthetic and ef~icient structures. In particular, illuminated and aesthetic protective canopies are being installed over the gasoline pumps. Many of these canopies have ~ signs, l~ights, or lighted faces along their fascias.~iIn ~' addition, wall mounted signs are also being installed on the buildings or su~rrounding structures. Many of these signs are also lighted for increased visibility.
Where the canopy fascias and wall signs are :
m-n~ted, one of the difficulties has ~een to create : ~ :
~;
WOg41l5141 PCT~S93/12~75 2 1 1 ~
::
a uniform light distribution on the outer (visible) surfaces. Typically, fluorescent bulbs (used internally) or spotlights (externally) are used and these types of illumination pro~ide uneven or nonuniform light distribution. Also, the fluorescent lights which are often 6, 8 or lO feet in length are difficult to change when they burn out. Changing burned out lights in conventional illuminated canopy and fascia systems is : an expensive and time-consuming task, often requiring a l~; lO boom truck or extension ladder. Moreover, it is often !,''' necessary to dismantle a portion of the canopy or fascia ~. - apparatus in order to change the lights.
; ' .!
i Another difficulty with known canopy fascia 'i systems as well as wall-mounted signs, concerns the ;~ 15 qua1ity and integrity of the sign panels. Weather ~; conditions and changes in temperature sometimes create ; ripples and waves in the sign panels reducing their ;
effectiveness and attractiveness. The durability of some types of sign panels has not been sufficient.
.. ~
Another problem with known illuminated canopy and fascia systems, as well as wall-mounted signs, concerns the corner intersections between adjacent .
~ surfaces. Some systems have had difficulty creating a :
uniform light pattern at these corners. Creating a smooth wrinkle-free surface at the corners and a clean edge is also a problem with some systems.
. ~ , ", I ~ i , .
It is an object of the present invention to p~ovide illuminated canopy and wall-mounted systems, particularly for service stations, which are improvements over known systems. It is another object of the present i~vention to pro~ide illuminated canopy and wall-mounted systems which distribute the light ;:
,, s . i ~ W0~4/15141 211~ 416 PCT~S93/12575 uniformly on and through the display faces of the systems.
.
It is also an object of the invention to ~~:
provide illuminated canopy and wall-mounted systems in ~' 5 which the Iight sources are easy to change and maintain.
; It is still another object of the invention to provide illuminated canopy and wall-mounted systems which are more energy efficient than known systems today, have ; improved lighting and have reduced cost for use and maintenance. An additional obiect of the invention is to provide illuminated canopy and wall-mounted systems which have improved illumination and aesthetics at the corners of adjacent panels.
. , These and other objects, features and .~ 15 advantages of the invention will become apparent from ~ the foll~owing description of the invention and appended ! claims, when viewed in accordance with the attached drawings.
Sum~arY of The In~ention ~ ~ !
~ ~ ZO The present invention provides improved '~ lIluminated canopy and wall-mounted systems for business establishments, such as ser~ice stations. The systems can be installed over existing fascias on the canopy and/or~on walllsur!fac~s~o~ the bu~ilding. ,~A "light b~x"
is provided having supporting brackets connected to a rear panel member or wall surface. A decorated flexible sheet member~is stretched across the face of each of the Iightboxes and held in place by extrusions which tension the sheet material. A plurality of lights (preferably ~metal halide lights) are provided in the light boxes.
A light dispersion film is placed over the light sources : ~ ;
. ~ .
WO94115141 PCT~S93/12575 '~ 21l~ 416 in order to distribute the light uniformly on the face of the sign panel. Trim caps are provided on the top and bottom of the lighting apparatus to ~orm an enclosed ; structure and make it weatherproof where necessary.
~ 5 Hinged access doors or removable panels are :'~ provided in the bottom of each of the structures adjacent the lights. The access members allow replacement of the lights either manually or with a ~ conventional tool. Also, for this purpose, an opening : lO can be provided in the light dispersion ~ilm or the film can be selectively detachable.
A curved clear plastic member is provided under the dispersion film for support. The support also ' has an opening in it to allow changing of the lights where necessary. Self-drilling screws are used to attach various parts together which allow a less expensive and faster met~od ~or assembly.

" .B~t Mode(s) ~or,Carryin~ Qut The Invention .
Figures 1-5~ illustrate the features and advanta~es of the present inventive illuminated canopy and fascia system. The pre~ent invention is ~ particula~rly suitable for use at gasoline service stations as shown~generally by the reference numeral lO
in~Figure 1. As shown, the ser~ice station has one or ~,:
-W~g4/15141 PC~S93112~7$
~,, ~,.
21~t6 , more islands 12 with a number of gasoline pumps 14 positioned on it and the entire area is covered with a canopy 16. A service facility or structure 18 is also provided under the canopies. The canopy covers the area where the ~ehicles 20 are parked to purchase gasoline.
The canopy protects the customers and vehicles from the weather elements and also provides a safe, well-illuminated area for use at'night.
Typically, a number of lights 21 are provided on the underside of the canopy 16 which project light downwardly for the customer's benefit. Not only does this allow the customer to use the facilities of the service station in a better manner, but also illuminates the entire service station and plaza area creating a pleasant and safe haven for motorists in nighttime hours. The lighting also allows the servlce station to be seen by motorists at a considerable distance.
The canopy 16 has fa~cia areas around its perimeter which are approximately 1-3 feet in height and ~ can be 10-20 feet or more in width. These fascia areas are indicated by the numerals 22, 24, 26 and 28 in Figure l. Typically, only the fascia areas which are exposed to passing motorists and are visible from a distance are illuminated. The illumination allows the name of the service station to be highlighted and also canl provide ~ferencelto some; of the servlces and facilities of the station. Typically, at least two and in most cases ~hree fascia areas of the canopies are illuminated. (The side of the canopy which faces away 3Q ~ from the road is usually not i1luminated.) The present invention is not limited to canopy and fascia systems, however. It is understood that the ~':
' ~ WO94/15141 214 ~ ~ 16 PCT~593/12~75 present invention could also be used for rear illumination light box structures l90 which can be installed on the walls or surfaces 23 of the building 18 and provide the same highlighted and illuminated names and information that are provided on the canopy fascias described above. In fact, some service stations include an illuminated light box structure on the faces of its buildings over the entrances that are counterparts ~o the illuminated fascia light box systems on the canopies over the gasoline pumps. One embodiment of the invention designed for use on a wall or other vertical ~ surface is designated by the reference numeral 190 and is discussed infra with reference to Figures 7-9.
The interior structure and configuration of the inventive light box structure is shown in Figures 2-5. The present invention is particularly adapted to be used on existing vertical or fascia structures, such as a wooden fascia board 30 as shown in Figure 2. In the light box structure 32, a plural~ty of support brackets or tubes 34 are provided which are bolted or otherwise secured to the existing fascia 30. The support brackets 34 can be steel tubing and can be secured to the fascia system by a plurality o~ bolts 35 or any other conventional means.
The support brackets 34 are curved U-shaped ~structures andjsupport el~ongated fascia frame e~trusions 42 at their outer ends 38 and 40. The frame extrusions 42 provide the upper and lower edges of the illuminated ; fascia apparatus and are represented by reference numerals 44 and 46, respectively. The frame extrusions 42 are made from extruded aluminum in the shape shown in Figures 2, 3 and 5 and are attached to the ends 38 and 40 of the support bracket 34 by one or more self-~: :
WO94115141 ~ - PCT~S93112~75 21~341~
., drilling screws 48. The self-drilling screws eliminate drilling of either the frame extrusion or ~he support bracket at the field site.i The extrusion 42 has a recess or channel 50 in which the ends 38 and 40 of the support bracket are positioned. Once the frame extrusions are positioned over a pair of support brackets, the support brackets are positioned in the channels 50 and secured in place with screws 48. The support brackets 34 in turn are secured to the fascia panel 30 and a solid secure unitary structure is formed on the fascia.
.
Stretched over the front of the light box structure 32 and held in place by the frame extrusions 42, is a translucent, flexible film panel 52. The panel 52 pxovides the illuminated ~acing of the fascias 22, 24, etc. of the canopy 16 of Figure l. The sign panel 52 preferably is a durable, flexible, translucent material, such as PanafIex 940 ~rom the 3M Company.
That material consists of a pq~yester scrim embedded between two layers of vinyl.
The names and letters 54 (Figure l) are preferably applied to the s1gn panel 52 and comprise a translucent pressure sensitive film. The preferred material in this regard is Scotchcal Series 3630 from the 3M Company. If desired, another pro~ective layer of transparent film can be positioned over the names and ~; numbers 54 for increased protection o~ the graphics. A
graphics protection film provided by 3M under the Scotchcal trade name could be utilized for this purpose.
:: : :
The flexible sign panel 52 is stretched over the~frame extrusions 42 and held in place as shown in Figures 2 and 5 by a tensioner angle extrusion 56~ The ~ WO94/15141 ~ 214 ~ 4 i 6 PCT~S93112~75 extrusion 56 is made from extruded aluminum material, extends along the length of the frame extrusion, and is held in place with a plurality of self-drilling screws 58. As shown, the flexible film 52 is wrapped around the angile extrusion 56 so that it is held tightly in place under tension when the screws 58 are installed in place.
The flexible film 52 is also held tightly in place under tension at the shorter ends of the light box. These ends are illustrated by the reference ~ numerals 60, 62 and 64 in Figure l; end 62 is shown in detail in Figure 4. In this regard, the ends of all of :.
adjacent light box structures 32 are tensioned and held in place at the shorter edges in the same manner. Thus, references to ~ight box 32 on one side of the fascia for canopy 16 would apply similarly to the light box structures on the other fascias of the canopy. ';
' ' The preferred corner ~tructure in accordance ::~ with the present invention includes a bent metal support : meimber 70. The corner 72 of the support member protrudes into and forms the corner 62 of the light box structure. The support member 70 is attached at one end : 74 to flange 76 on the frame extrusion 42 (see Figure ~; ' 2). The second end 78 of the support member 70 is also attached to the flange 76~of the frame extrusion 42.
; ' ! The ang,le o~thç suppo,rt,member 70,allows light from the : light source, as described below, to reach the corners :~ : 62 :and still provides a strong solid support for the ~ sign~panel'52~ at the corner.
~ .
~: : 30 Bracket 80 is also attached to the end of the support member 70. Bracket 80 is adapted to hold a tensioning screw 82 and a second tensioning bracket 84.
.~
WO94115141 , - PICT~S93/1~575 21~416 The end 86 of the flexible sign panel 52 in turn is wrapped around a elongated member 88 and secured by a self-drilling screw 90 to the bracket 84. In this manner, when the end 86 of the film 52 is held in place S by brackets 88 and 84, the bolt 82 can then be tightened which pulls the film 52 tigh~ly in place in the corner 62.
A shield 92 is secured to the fascia structure 30 and extends outwardly at an angle. The shield is positioned between adjacent lightboxes on a canopy and ~ prevents light from one 'lightbox from entering an adjacent lightbox. The shield 92 preferably is made from a thin sheet of reflective aluminum material, or is coated with a:reflective material.
~ lS The light source for the illuminated canopy :~ and fascia system is shown in Figures 2 and 3. A
. plurality of metal halide lights (or lamps) lO0 are positioned along the fascia pane~ 30. The lights lO0 are screwed into conventional light sockets 102 which are~connected to the fascla panel 30 by brackets 104.
The metal halide lights are preferably high intensity discharge (HID) lights. These are more :: : : efficient and provide ~ore lumens per watt of energy ~: than regular light bulbs. Preferably, metal halide 25 ~i lamps of 150-1,75, watts,~are~utili~ed for the illuminated canopy and fascia system. With lights of this . intensity, the lamps lO0 can be provided every five to : nine feet along the length of the fascia, and preferably every 8 feet. The spacing of the lights provides for better energy consumption and light output. No~ only do the metal halide HID lights lO0 provide a more efficient liyht source for a canopy and fascia system, but the ~ ~ :
~Og4/1~141 21~ 9 916 PCT~S93/12575 '' .
individual light bulbs are easier to service and replace, as explained below.
It is also possible in accordance with the present in~ention to use light sources other than metal halide lamps to provide the necessary illumination.
Such light sources could be conventional incandescent lamps, mercury ~apor lamps, other HID lamps, although a point light source is necessary. Metal halide lights are preferred due to their color temperature properties.
In order to reduce operation and replacement costs, the sizes of the light sources should be kept as small as possible. In this regard, a balance might need to be made between the spacing and size of the light sources which would~provide the desired illumination intensity and distribution, and~ which also would minimize operating and replacement costs.
:
One or more ballasts 1~0 are provided for the metal halide lights. The size and number of ballas~s will depend on the sizes and number o~ light sources utilized and the illumination intensity desired on the sign panel~52. The ballasts are of a conventional type and do not need further explanation or description here.
A ballast can be provided on the opposite side of the fascia panel 30 from the lights 100 if there is 25'~i~suf~ici~ent space (as sh~wn in Figure 2),~or thé ballast i can be positloned internally along an lnside edge of the light box ~a~s~shown~by phantom lines 110' in Figu.re 2).
Conventional wiring~lll is used to connect the lights to the ballasts and~the ballasts in turn to a plug or power 30~ source (not shown;).
.
21~ ~ 416 PCT~S93112575 ~
If necessary to mlnimize shadows and provide better light distributlon on the face of the film 52, the angle or positioning of the lights lO0 relative to the fascia 30 can be changed or adjusted as desired.
5For example, the lights lO0 could be set at horizontal or vertical angles relative to the ~ascia to eliminate shadows caused by support brackets, ballasts or other internal structures.
A pair of elongated aluminum trim caps are lOprovided to enclose the interior of the light box apparatus. The trim caps comprise an upper panel member 114 and a lower panel member 116. The caps can be attached to the ends of the fascia panel 30 when needed as well as to a flange 118 on the fa~cia ex~rusions 42.
15The connection of the top and bottom trim caps 114 and 115 to the fascia panel and frame extrusions 42 can be with any conventional means, such as self-drilling scre~s 120.
A light dispersion panel 130 i5 provided 20around each of the metal halide light sources lO0.
Panel 130 distributes the light uniformly on the inside surface of the sign panel 52. Preferably, the light ~ dispersion panel 130 is the Varilume patterned film ; product produced by TIR Systems Ltd. in British ~5Columbia, Canada. The Varilume fil~ product has a plurality oflope~ings on ithe face of the film, the openings being si~ed and arranged in a certain pattern designed for allowing diffexing amounts of light to pass through the film at different areas~
3DAnother method for diffusing illumination from light sources and spreading it evenly over a surface is ~, ~shown and descri~ed in U.S. Patent No. 4,267~489.
':
~ W094/1~141 214 9 ~16 PCT~S93/12575 The light dispersion panels 130 are formed as curved structures around each of the light sources lO0 and positioned between the light sources and the flexible front panel 52. To keep the film 130 in position and prevent it from sagging and thus changing the light dispersion pattern, a curved support member 132 is provided. The support member 132 can be made of any conventional clear plastic material which satisfies the functions and purposes of the present invention, but preferably is a clear polycarbonate material approximately .030 inches in thickness.
-Both the~ film 130 and support members 132 areconnected to the fascia panel 30 by elongated rigid strip members l33, 134 and 136. The elongated edges of the film and support members are bent (e.g. by an angle break) to provide a flat portion adjacent the s~rip members. Self-drilling screws 120 are positioned through the film, support members and strip members and used to secure the film and support members to the fascia. The strip me~ers should have a low profile to eliminate shadows or light blockages which might affect ;~ the light distribution on the sign panel.
In order to increase the evenness and intensity of the light distribution on the front panel 52, a specular reflective surface 31 is provided on the ~fascia 30 behind ~he~liyht sources lO0. The surface 31 could be coated with a highly reflective paint (such as '~ ; white), or a type of mirrored specular reflector could be pro~ided~(such as bright aluminum reflector film).
Also, in order~to minimize shadows caused by ~he light sockets 102, a curved half-moon portion 33 of the fascia immediately behind the li~ht sockets is left uncovered by the specular reflective surface. Similarly, curved W~94/15141 2 ~ 4 ~ 416 ~ ~ PCT~S93/1257~
~., !, surfaces 35 are provided ln thei ends of the re~lecti~e surface to provide a more uniform light dispersion pattern on the front panel.
One of the features of the invention is that the lights l00 can be easily and quickly replaced when they burn out. For this purpose, a hinged access door 150 is provided in the bottom 116 of the fascia, and a curved opening or cutout 152 is provided in the light dispersion panel 130 and in the curved backing member 132. These are shown in Figures 3-5.
An access door 150 and opening 152 are provided in axial alignment with each of the metal halide lights l00 ~as shown in Figure 3). The access door 150 is connected by hinges l54 so it can be opened ; 15 to positlon 150' (shown in phantom in ~igure 5). The hinge plates 158 pivotably attached to the door lS0 are attached to trim cap member 116 and door 150 by pop rivets 160 Preferably, a conv~ntional biasing spring 156 is provided in the hinges 154 so that the door 150 will automatically return to its closed position after the light bulb has been replaced. In this manner, the light bulb can be replaced from the ground with an elongated pole device which can be inserted manually up through the door 150 and the door will return to its closed position after the pole and light bulb are removed.
Po1e type l1ght bulb replacement devices with spring biased fingers~and the like which are used to grip a light bulb so it can be unscrewed and removed are conventionally known and available. Of course, other :~ t~pes of light bulb removing devices and configurations of access openings through the fascia structure can be ~:;

A sleeve 155 is positioned in the opening 152 to facilitate replacement of the light bulb without 5damaging the film 130 and support members 132. The sleeve 155 preferably is a U-shaped member made of aluminum and is connected to the fascia 30 by screws or other con~entional ~asteners. The sleeve 155 also prevents formation of a shadow pattern on the front lOpanel caused by the edges of the opening 152.
:
Although a cutout 152 access opening is preferably pro~ided in the panel 130 and backing member 132 for removal and replacement of the lights lO0, it is aiso possible in the alternative to have the bottom 15edges of the panel 130 and backing member 132 be removably attached to the fascia 30. In this manner, when a light l00 needed replacement, access through door 150 and detachment of panel 130 ~nd backing member 132 rom the fascia could also be easily and conveniently 20made.
A cutout opening lS7 is preferably pro~ided in the panel 130 and backing me~ber 132 above the light ~'~' source for temperature control or relief. This openlng ::

ILhTJMI~ATED CANOPY SYSTEM
~, .
.
Technical Field The present inventlon relates to lighted ;~ canopy and wall systems, particularly for gasoline service stations and other business establishments. The ~ascias of the canopies have transpar~nt displays which ' are illuminated from the rear for visibility and ., ~
aesthetics. Similarly, back-lit lightboxes are mounted on the buildings.
.
: Backqrou~d of The Invention , ~
Businesses with outdoor service areas, such as gasoline service s~ations, are taking steps today to improve the facilities and areas around them. The companies want to keep their places of business , attractive ~or custo~ers, keep the appearances on par with other businesses, and also make the facilities better illuminated and safer in non-daylight hours.
I ; Service stations in particular today are improYing the areas around their buildings and gasoline pumps by providing increased lighting and more aesthetic and ef~icient structures. In particular, illuminated and aesthetic protective canopies are being installed over the gasoline pumps. Many of these canopies have ~ signs, l~ights, or lighted faces along their fascias.~iIn ~' addition, wall mounted signs are also being installed on the buildings or su~rrounding structures. Many of these signs are also lighted for increased visibility.
Where the canopy fascias and wall signs are :
m-n~ted, one of the difficulties has ~een to create : ~ :
~;
WOg41l5141 PCT~S93/12~75 2 1 1 ~
::
a uniform light distribution on the outer (visible) surfaces. Typically, fluorescent bulbs (used internally) or spotlights (externally) are used and these types of illumination pro~ide uneven or nonuniform light distribution. Also, the fluorescent lights which are often 6, 8 or lO feet in length are difficult to change when they burn out. Changing burned out lights in conventional illuminated canopy and fascia systems is : an expensive and time-consuming task, often requiring a l~; lO boom truck or extension ladder. Moreover, it is often !,''' necessary to dismantle a portion of the canopy or fascia ~. - apparatus in order to change the lights.
; ' .!
i Another difficulty with known canopy fascia 'i systems as well as wall-mounted signs, concerns the ;~ 15 qua1ity and integrity of the sign panels. Weather ~; conditions and changes in temperature sometimes create ; ripples and waves in the sign panels reducing their ;
effectiveness and attractiveness. The durability of some types of sign panels has not been sufficient.
.. ~
Another problem with known illuminated canopy and fascia systems, as well as wall-mounted signs, concerns the corner intersections between adjacent .
~ surfaces. Some systems have had difficulty creating a :
uniform light pattern at these corners. Creating a smooth wrinkle-free surface at the corners and a clean edge is also a problem with some systems.
. ~ , ", I ~ i , .
It is an object of the present invention to p~ovide illuminated canopy and wall-mounted systems, particularly for service stations, which are improvements over known systems. It is another object of the present i~vention to pro~ide illuminated canopy and wall-mounted systems which distribute the light ;:
,, s . i ~ W0~4/15141 211~ 416 PCT~S93/12575 uniformly on and through the display faces of the systems.
.
It is also an object of the invention to ~~:
provide illuminated canopy and wall-mounted systems in ~' 5 which the Iight sources are easy to change and maintain.
; It is still another object of the invention to provide illuminated canopy and wall-mounted systems which are more energy efficient than known systems today, have ; improved lighting and have reduced cost for use and maintenance. An additional obiect of the invention is to provide illuminated canopy and wall-mounted systems which have improved illumination and aesthetics at the corners of adjacent panels.
. , These and other objects, features and .~ 15 advantages of the invention will become apparent from ~ the foll~owing description of the invention and appended ! claims, when viewed in accordance with the attached drawings.
Sum~arY of The In~ention ~ ~ !
~ ~ ZO The present invention provides improved '~ lIluminated canopy and wall-mounted systems for business establishments, such as ser~ice stations. The systems can be installed over existing fascias on the canopy and/or~on walllsur!fac~s~o~ the bu~ilding. ,~A "light b~x"

" .B~t Mode(s) ~or,Carryin~ Qut The Invention .
Figures 1-5~ illustrate the features and advanta~es of the present inventive illuminated canopy and fascia system. The pre~ent invention is ~ particula~rly suitable for use at gasoline service stations as shown~generally by the reference numeral lO
in~Figure 1. As shown, the ser~ice station has one or ~,:
-W~g4/15141 PC~S93112~7$
~,, ~,.
21~t6 , more islands 12 with a number of gasoline pumps 14 positioned on it and the entire area is covered with a canopy 16. A service facility or structure 18 is also provided under the canopies. The canopy covers the area where the ~ehicles 20 are parked to purchase gasoline.
The canopy protects the customers and vehicles from the weather elements and also provides a safe, well-illuminated area for use at'night.
Typically, a number of lights 21 are provided on the underside of the canopy 16 which project light downwardly for the customer's benefit. Not only does this allow the customer to use the facilities of the service station in a better manner, but also illuminates the entire service station and plaza area creating a pleasant and safe haven for motorists in nighttime hours. The lighting also allows the servlce station to be seen by motorists at a considerable distance.
The canopy 16 has fa~cia areas around its perimeter which are approximately 1-3 feet in height and ~ can be 10-20 feet or more in width. These fascia areas are indicated by the numerals 22, 24, 26 and 28 in Figure l. Typically, only the fascia areas which are exposed to passing motorists and are visible from a distance are illuminated. The illumination allows the name of the service station to be highlighted and also canl provide ~ferencelto some; of the servlces and facilities of the station. Typically, at least two and in most cases ~hree fascia areas of the canopies are illuminated. (The side of the canopy which faces away 3Q ~ from the road is usually not i1luminated.) The present invention is not limited to canopy and fascia systems, however. It is understood that the ~':
' ~ WO94/15141 214 ~ ~ 16 PCT~593/12~75 present invention could also be used for rear illumination light box structures l90 which can be installed on the walls or surfaces 23 of the building 18 and provide the same highlighted and illuminated names and information that are provided on the canopy fascias described above. In fact, some service stations include an illuminated light box structure on the faces of its buildings over the entrances that are counterparts ~o the illuminated fascia light box systems on the canopies over the gasoline pumps. One embodiment of the invention designed for use on a wall or other vertical ~ surface is designated by the reference numeral 190 and is discussed infra with reference to Figures 7-9.
The interior structure and configuration of the inventive light box structure is shown in Figures 2-5. The present invention is particularly adapted to be used on existing vertical or fascia structures, such as a wooden fascia board 30 as shown in Figure 2. In the light box structure 32, a plural~ty of support brackets or tubes 34 are provided which are bolted or otherwise secured to the existing fascia 30. The support brackets 34 can be steel tubing and can be secured to the fascia system by a plurality o~ bolts 35 or any other conventional means.
The support brackets 34 are curved U-shaped ~structures andjsupport el~ongated fascia frame e~trusions 42 at their outer ends 38 and 40. The frame extrusions 42 provide the upper and lower edges of the illuminated ; fascia apparatus and are represented by reference numerals 44 and 46, respectively. The frame extrusions 42 are made from extruded aluminum in the shape shown in Figures 2, 3 and 5 and are attached to the ends 38 and 40 of the support bracket 34 by one or more self-~: :
WO94115141 ~ - PCT~S93112~75 21~341~
., drilling screws 48. The self-drilling screws eliminate drilling of either the frame extrusion or ~he support bracket at the field site.i The extrusion 42 has a recess or channel 50 in which the ends 38 and 40 of the support bracket are positioned. Once the frame extrusions are positioned over a pair of support brackets, the support brackets are positioned in the channels 50 and secured in place with screws 48. The support brackets 34 in turn are secured to the fascia panel 30 and a solid secure unitary structure is formed on the fascia.
.
Stretched over the front of the light box structure 32 and held in place by the frame extrusions 42, is a translucent, flexible film panel 52. The panel 52 pxovides the illuminated ~acing of the fascias 22, 24, etc. of the canopy 16 of Figure l. The sign panel 52 preferably is a durable, flexible, translucent material, such as PanafIex 940 ~rom the 3M Company.
That material consists of a pq~yester scrim embedded between two layers of vinyl.
The names and letters 54 (Figure l) are preferably applied to the s1gn panel 52 and comprise a translucent pressure sensitive film. The preferred material in this regard is Scotchcal Series 3630 from the 3M Company. If desired, another pro~ective layer of transparent film can be positioned over the names and ~; numbers 54 for increased protection o~ the graphics. A
graphics protection film provided by 3M under the Scotchcal trade name could be utilized for this purpose.
:: : :
The flexible sign panel 52 is stretched over the~frame extrusions 42 and held in place as shown in Figures 2 and 5 by a tensioner angle extrusion 56~ The ~ WO94/15141 ~ 214 ~ 4 i 6 PCT~S93112~75 extrusion 56 is made from extruded aluminum material, extends along the length of the frame extrusion, and is held in place with a plurality of self-drilling screws 58. As shown, the flexible film 52 is wrapped around the angile extrusion 56 so that it is held tightly in place under tension when the screws 58 are installed in place.
The flexible film 52 is also held tightly in place under tension at the shorter ends of the light box. These ends are illustrated by the reference ~ numerals 60, 62 and 64 in Figure l; end 62 is shown in detail in Figure 4. In this regard, the ends of all of :.
adjacent light box structures 32 are tensioned and held in place at the shorter edges in the same manner. Thus, references to ~ight box 32 on one side of the fascia for canopy 16 would apply similarly to the light box structures on the other fascias of the canopy. ';
' ' The preferred corner ~tructure in accordance ::~ with the present invention includes a bent metal support : meimber 70. The corner 72 of the support member protrudes into and forms the corner 62 of the light box structure. The support member 70 is attached at one end : 74 to flange 76 on the frame extrusion 42 (see Figure ~; ' 2). The second end 78 of the support member 70 is also attached to the flange 76~of the frame extrusion 42.
; ' ! The ang,le o~thç suppo,rt,member 70,allows light from the : light source, as described below, to reach the corners :~ : 62 :and still provides a strong solid support for the ~ sign~panel'52~ at the corner.
~ .
~: : 30 Bracket 80 is also attached to the end of the support member 70. Bracket 80 is adapted to hold a tensioning screw 82 and a second tensioning bracket 84.
.~
WO94115141 , - PICT~S93/1~575 21~416 The end 86 of the flexible sign panel 52 in turn is wrapped around a elongated member 88 and secured by a self-drilling screw 90 to the bracket 84. In this manner, when the end 86 of the film 52 is held in place S by brackets 88 and 84, the bolt 82 can then be tightened which pulls the film 52 tigh~ly in place in the corner 62.
A shield 92 is secured to the fascia structure 30 and extends outwardly at an angle. The shield is positioned between adjacent lightboxes on a canopy and ~ prevents light from one 'lightbox from entering an adjacent lightbox. The shield 92 preferably is made from a thin sheet of reflective aluminum material, or is coated with a:reflective material.
~ lS The light source for the illuminated canopy :~ and fascia system is shown in Figures 2 and 3. A
. plurality of metal halide lights (or lamps) lO0 are positioned along the fascia pane~ 30. The lights lO0 are screwed into conventional light sockets 102 which are~connected to the fascla panel 30 by brackets 104.
The metal halide lights are preferably high intensity discharge (HID) lights. These are more :: : : efficient and provide ~ore lumens per watt of energy ~: than regular light bulbs. Preferably, metal halide 25 ~i lamps of 150-1,75, watts,~are~utili~ed for the illuminated canopy and fascia system. With lights of this . intensity, the lamps lO0 can be provided every five to : nine feet along the length of the fascia, and preferably every 8 feet. The spacing of the lights provides for better energy consumption and light output. No~ only do the metal halide HID lights lO0 provide a more efficient liyht source for a canopy and fascia system, but the ~ ~ :
~Og4/1~141 21~ 9 916 PCT~S93/12575 '' .
individual light bulbs are easier to service and replace, as explained below.
It is also possible in accordance with the present in~ention to use light sources other than metal halide lamps to provide the necessary illumination.
Such light sources could be conventional incandescent lamps, mercury ~apor lamps, other HID lamps, although a point light source is necessary. Metal halide lights are preferred due to their color temperature properties.
In order to reduce operation and replacement costs, the sizes of the light sources should be kept as small as possible. In this regard, a balance might need to be made between the spacing and size of the light sources which would~provide the desired illumination intensity and distribution, and~ which also would minimize operating and replacement costs.
:
One or more ballasts 1~0 are provided for the metal halide lights. The size and number of ballas~s will depend on the sizes and number o~ light sources utilized and the illumination intensity desired on the sign panel~52. The ballasts are of a conventional type and do not need further explanation or description here.
A ballast can be provided on the opposite side of the fascia panel 30 from the lights 100 if there is 25'~i~suf~ici~ent space (as sh~wn in Figure 2),~or thé ballast i can be positloned internally along an lnside edge of the light box ~a~s~shown~by phantom lines 110' in Figu.re 2).
Conventional wiring~lll is used to connect the lights to the ballasts and~the ballasts in turn to a plug or power 30~ source (not shown;).
.
21~ ~ 416 PCT~S93112575 ~
If necessary to mlnimize shadows and provide better light distributlon on the face of the film 52, the angle or positioning of the lights lO0 relative to the fascia 30 can be changed or adjusted as desired.
5For example, the lights lO0 could be set at horizontal or vertical angles relative to the ~ascia to eliminate shadows caused by support brackets, ballasts or other internal structures.
A pair of elongated aluminum trim caps are lOprovided to enclose the interior of the light box apparatus. The trim caps comprise an upper panel member 114 and a lower panel member 116. The caps can be attached to the ends of the fascia panel 30 when needed as well as to a flange 118 on the fa~cia ex~rusions 42.
15The connection of the top and bottom trim caps 114 and 115 to the fascia panel and frame extrusions 42 can be with any conventional means, such as self-drilling scre~s 120.
A light dispersion panel 130 i5 provided 20around each of the metal halide light sources lO0.
Panel 130 distributes the light uniformly on the inside surface of the sign panel 52. Preferably, the light ~ dispersion panel 130 is the Varilume patterned film ; product produced by TIR Systems Ltd. in British ~5Columbia, Canada. The Varilume fil~ product has a plurality oflope~ings on ithe face of the film, the openings being si~ed and arranged in a certain pattern designed for allowing diffexing amounts of light to pass through the film at different areas~
3DAnother method for diffusing illumination from light sources and spreading it evenly over a surface is ~, ~shown and descri~ed in U.S. Patent No. 4,267~489.
':
~ W094/1~141 214 9 ~16 PCT~S93/12575 The light dispersion panels 130 are formed as curved structures around each of the light sources lO0 and positioned between the light sources and the flexible front panel 52. To keep the film 130 in position and prevent it from sagging and thus changing the light dispersion pattern, a curved support member 132 is provided. The support member 132 can be made of any conventional clear plastic material which satisfies the functions and purposes of the present invention, but preferably is a clear polycarbonate material approximately .030 inches in thickness.
-Both the~ film 130 and support members 132 areconnected to the fascia panel 30 by elongated rigid strip members l33, 134 and 136. The elongated edges of the film and support members are bent (e.g. by an angle break) to provide a flat portion adjacent the s~rip members. Self-drilling screws 120 are positioned through the film, support members and strip members and used to secure the film and support members to the fascia. The strip me~ers should have a low profile to eliminate shadows or light blockages which might affect ;~ the light distribution on the sign panel.
In order to increase the evenness and intensity of the light distribution on the front panel 52, a specular reflective surface 31 is provided on the ~fascia 30 behind ~he~liyht sources lO0. The surface 31 could be coated with a highly reflective paint (such as '~ ; white), or a type of mirrored specular reflector could be pro~ided~(such as bright aluminum reflector film).
Also, in order~to minimize shadows caused by ~he light sockets 102, a curved half-moon portion 33 of the fascia immediately behind the li~ht sockets is left uncovered by the specular reflective surface. Similarly, curved W~94/15141 2 ~ 4 ~ 416 ~ ~ PCT~S93/1257~
~., !, surfaces 35 are provided ln thei ends of the re~lecti~e surface to provide a more uniform light dispersion pattern on the front panel.
One of the features of the invention is that the lights l00 can be easily and quickly replaced when they burn out. For this purpose, a hinged access door 150 is provided in the bottom 116 of the fascia, and a curved opening or cutout 152 is provided in the light dispersion panel 130 and in the curved backing member 132. These are shown in Figures 3-5.
An access door 150 and opening 152 are provided in axial alignment with each of the metal halide lights l00 ~as shown in Figure 3). The access door 150 is connected by hinges l54 so it can be opened ; 15 to positlon 150' (shown in phantom in ~igure 5). The hinge plates 158 pivotably attached to the door lS0 are attached to trim cap member 116 and door 150 by pop rivets 160 Preferably, a conv~ntional biasing spring 156 is provided in the hinges 154 so that the door 150 will automatically return to its closed position after the light bulb has been replaced.
