Definitions
- This invention relates generally in some aspects to the field of illuminated signs and displays and in other aspects to the mounting of electronic circuit devices such as light emitting diodes to circuit boards and ribbons.
- Illuminated display signs are conventionally formed as neon tubes or as translucent panels backlit by fluorescent tubes or by incandescent lamps. Often, the two are combined in the one configuration. Neon signs have been a pervasive presence in the night time ambience of urban commercial precincts for many years. A survey of any one of these precincts at any given time will reveal a significant proportion of poorly or partly functioning neon tube signs. Frequently, signs are in imperfect order for extended periods, reflecting the time and cost involved in fault rectification.
- LEDs light emitting diodes
- housings within elongate part tubular housings. These housings are attached in turn to backing rails and thereby employed to highlight commercial or building features such as sign boards and external ridges or edges.
- the housings are formed in a material which disperses the LED light so that the housings glow as a strip or line of light.
- the present applicant's international patent application PCT/AU 01/00630 extends the use of solid state lamp devices to illuminated signs.
- an array of solid state lamp devices such as LEDs backlight an overlying translucent sheet and thereby cause illumination of sign content provided on, or in conjunction with, the sheet.
- the invention involves an appreciation that it is possible to incorporate spaced light sources such as solid state lamp devices into a construction which may be adapted to substitute for neon tube technology.
- the invention accordingly provides, in a first aspect, illuminated sign or display apparatus including:
- an elongate translucent body mounted in said opening; and • means for retaining a plurality of spaced light sources at a first side of said support structure in proximity to said elongate body, whereby said body and said light sources are mutually arranged so that the light sources when activated cause said body to glow and to appear, at a second side of said support structure, as a strip or line of light.
- the invention provides illuminated sign or display apparatus including:
- the spaced light sources are preferably solid state light devices such as light emitting diode devices.
- the light sources, especially the latter preferred light sources, are advantageously incorporated in the illuminated sign apparatus and are retained at the first side of the support structure in proximity to the elongate body.
- the elongate translucent body is light dispersive, more preferably so that the strip or line of light appears to be of substantially uniform brightness.
- the light sources may be individually visible and/or the strip or line of light may be non-continuous, and/or of variable brightness, and/or an array, eg. a linear array, of segments.
- the means for retaining the plurality of spaced light sources at the first side of the support structure is such that the light sources are, when in position, mounted to the elongate body.
- the retaining means comprises a formation on the body defining a recess in which the light sources may be mounted.
- the retaining means is a clip or clip configuration removably attachable to the elongate body.
- the solid state light devices or light emitting diode devices typically comprise packages in each of which the solid state light element, for example a light emitting diode, is mounted on a substrate that has terminals by which electrical power may be supplied to the package for activating the solid state light element.
- the solid state light element for example a light emitting diode
- multiple solid state light devices are fixed at spaced intervals to an electrical circuit board or ribbon.
- the elongate translucent and preferably light dispersive body is advantageously an extruded piece of substantially uniform cross section.
- a suitable material is a polyvinyl chloride plastics polymer or a silicone rubber.
- the elongate body may be substantially solid or may include a longitudinally extending cavity which in the assembled apparatus is disposed at or towards the second side of the support structure.
- the elongate translucent body preferably includes deformable longitudinally extending formations such as ribs whereby the body may be pushed through the elongate opening in the support structure and held in place by engagement of these formations with the support structure.
- the support structure may conveniently be a panel.
- This panel would in a typical practical application form an outer face of a sign housing.
- the sign housing may further include other light sources, eg fluorescent tubes or incandescent lamps, positioned to backlight the panel support structure.
- the sign housing may further include other light sources, eg fluorescent tubes or incandescent lamps, positioned to backlight the panel support structure.
- the elongate translucent body projects above the surrounding support structure so as to have the appearance of an elongate tube.
- This portion of the body may be solid or tubular and may be of generally curved, circular or elliptical appearance, at least on its exposed surface.
- an array of solid state light devices for example light emitting diode devices, in which the light devices are fixed along and project laterally from an edge of a circuit board or ribbon with their central axes generally parallel to the plane of the board or ribbon and at least two electrical contacts, eg. contact pins, of each light device in operative contact with the circuit on the board or ribbon.
- the invention further provides an assembly of an electronic circuit device and a circuit board or ribbon, wherein the electronic circuit device has at least two contact pins depending therefrom and the circuit device is mounted at an edge of the circuit board or ribbon with said at least two contact pins conductively attached to respective faces of the board or ribbon.
- the electronic circuit device is a solid state light source, eg. a light emitting diode.
- the electronic circuit device is a solid state light source, eg. a light emitting diode.
- the third aspect of the invention is utilised for the mounting of the solid state light devices in the first and second aspects of the invention.
- a light tube including:
- an elongate translucent body defining a longitudinally extending cavity
- an elongate electrical circuit board or ribbon supporting said solid state light devices at intervals along said cavity wherein the solid state light devices are fixed along and project laterally from an edge of said circuit board or ribbon;
- solid state light devices are fixed along and project laterally from an edge of said circuit board or ribbon with their central axes generally parallel to the plane of the board or ribbon and at least two electrical contacts of each light device in operative contact with the circuit on the board or ribbon.
- a light tube including:
- an elongate translucent body defining a pair of longitudinally extending cavities
- the solid state light devices are fixed along and project laterally from an edge of the circuit board or ribbon with their central axes generally parallel to the plane of the board or ribbon and at least two electrical contacts of each light device in operative contact with the circuit on the board or ribbon.

- Figure 14 is an alternative embodiment to that of Figures 1 to 3;
- Figure 15 depicts application of the embodiment of Figure 14 to back- illumination in a sign canister
- Figures 16 and 17 are an exploded isometric view and a cross-section of a further embodiment of the invention.
- Figure 18 is a simple illustration of the use of the embodiments of Figures 14, 16 and 17.
- the sign apparatus illustrated in Figure 1 is diagrammatically represented as a simple sign displaying an upper case "A" on a plain background.
- the plain background is provided by a cover panel 12 for an open-topped housing 14 in the form of a generally rectangular box.
- this housing would typically also include one or more fluorescent tubes, or possibly suitable incandescent lamps, for backlighting panel 12.
- Panel 12 would typically be a translucent or partially transparent polycarbonate sheet of a selected colour.
- the character "A” is provided in accordance with an exemplary embodiment of the invention. It is defined by three elongate, transverse, translucent and preferably light dispersive solid bodies 16 (separately indicated in Figure 1 as 16a, 16b, 16c) mounted in matching elongate openings 18 in the support structure provided by panel 12.
- Bodies 16 comprise extrusions of a selected polyvinyl chloride material of uniform cross section of the form shown in Figure 2.
- the principal components of this cross section are an outer portion 20 of generally cylindrical appearance, mid-portion 22 which lies in opening 18, and inner portion 24.
- Portion 24 defines, along the rear face of the extrusion, a longitudinally extending recess 26 that snugly receives, at spaced intervals, LED packages 30.
- Packages 30 are retained by return lips 25, which may typically be resiliently deflectable to allow packages 30 to be snapped into place.
- Inner portion 24 is also dimensioned to fit through opening 18 and the extrusion is held in place in the opening by the co-operation with panel 12 of respective flared ribs 28 that engage the outer surface of the panel and deflectable flanges 29 that are inclined so as to each deflect into a respective matching depression 27 in the sides of the extrusion as it is pushed through the opening 18 from the outside of panel 12.
- These flanges 29 snap back under panel 12 when the extrusion reaches its desired location and the panel 12 is gripped between ribs 28 and flanges 29.
- LED packages 30 are commercially available packages comprising a body or base 32, four depending contact leads 33 arranged in a square array, and the actual light emitting diode 34. Suitable LEDs include the Super Flux, High Flux or 5mm LEDs supplied by LumiLeds or Agilent Technologies, but any other appropriate LED may be employed. LEDs 34 seat snugly in a longitudinally extending groove or channel 36 in the surface of recess 26.
- Electrical power for activating LEDs 34 is delivered from a power pack 42 to the array of LEDs along extrusion 16 via a printed circuit board (pcb) or circuit ribbon 40.
- a preferred arrangement in accordance with an embodiment of the third aspect of the invention, that utilises edge mounting of the LEDs to a flexible circuit ribbon, is detailed in Figures 3 to 6.
- the packages 30 are fixed along and project laterally from an edge of the ribbon, rather than being surface mounted as is the conventional arrangement, with their central axes generally parallel to the plane of the ribbon and their pins conductively attached to respective faces of the ribbon.
- the electrical contacts or legs 33 of the LED packages are soldered to contact pins 96 projecting from the ribbon surface and are thereby in operative electrical contact with the circuit 94 on ribbon 40.
- the normally straight legs 33' are bent inwardly at an angle to respective tips 33a that are folded back and lie flat against and are soldered to the ribbon circuit.
- the ribbon 40' is effectively sandwiched between the respective pairs of LED legs.
- FIG. 6 A further variation of the pin configuration is shown in Figure 6: the pins of each opposed pair of pins 33" are bent in towards each other, then outwardly with respect to body or base 32.
- the pins include aligned intermediate portions 133 generally parallel to but spaced from body or base 32, curving into splayed or divergent outward end portions 134. These end portions 134 are overturned and lie over intermediate portions 133. End portions 134 contact or almost contact but are separable to receive and grip the circuit ribbon to which they are then soldered. The splaying facilitates location relative to the ribbon in automatic assembly equipment.
- FIG. 7 illustrates an arrangement for providing smaller surface-mounted LEDs in recess 26, but still using flexible ribbon 40.
- Each LED 34' is on an individual projecting tab 98 of a castellated edge 99 of the ribbon.
- Each tab 98 is bent at 90° to place the LED at the inner face of the recess 26, while spaced packers 100 that interlock with the recess locate and maintain ribbon 40 as it trails rearwardly of the recess.
- the power pack is depicted purely schematically at 42 in Figure 2. It will be appreciated that the power pack may include a programmable controller by which the sign apparatus may be animated, eg. the LEDs may be activated on and off in any desired sequence to create static or moving patterns of illumination. It will also be appreciated that more complex LED arrays might be used, for example LED packages having multiple LEDs of different colours or power outputs, or different coloured LEDs interspersed along the extrusion 16.
- extrusion 16, 16' may be chosen with respect to the arrangement of the extrusion and LEDs 34 so that the material uniformly disperses the light from the LEDs and the appearance is substantially that of uniform brightness along the length of the extrusion.
- the use of a light dispersant or diffusing material in the extrusion is optional.
- the appearance of individual light sources will have a beneficial visual effect.
- the extrusion and the LEDs are preferably mutually arranged so that the light sources when activated cause the strip to glow and appear from in the front of panel 12 as a strip or line of light.
- a suitable material for the extrusion is a polyvinyl chloride polymer.
- a material treated or doped with an additive that causes the extrusions to have a residual fluorescing effect ie. they continue to glow for some time, eg. several hours, after the LEDs 34 are deactivated and the material is no longer illuminated.
- Figure 1 is only a simplified representation indicating the potential of the invention.
- multiple lengths of the translucent and preferably light dispersive extrusion may be arranged to provide, within the physical constraints of the manipulation of the material, selected symbols, characters or patterns. In this way, the invention provides the ability to supplant traditional neon tube technology.
- FIG 8 in which like numerals preceding by a "1" indicate like parts, illustrates a second embodiment of the invention.
- the LED package 30 is mounted to the translucent and light dispersive extrusion 116 by means of a complementary u- shaped clip 50.
- Clip 50 fits about the inner edge of the extrusion and is held in place by deflectable arms 52 releasably engaging opposed ribs 54 of semi-circular cross-section on the side faces of the extrusion.
- This embodiment also differs from the first in that the extrusion is arranged to be pushed through opening 118 from behind rather than from above: to this end, the cylindrical portion 120 is of a diameter smaller than the width of opening 118 and the inclined retractable flanges 129 sit on the outside of panel 112.
- the components of the sign may be supplied in flexible kit form to facilitate the construction of custom- made signs by local signmakers.
- This process is set out in the sequence of diagrams 1 to 7 in Figure 9, applying the embodiment of Figure 8.
- a panel 12 is first cut from a larger sheet 11 of polycarbonate material.
- the outline 17 of the symbol or character is then accurately formed on one face of panel 12 (step 2), and then the required elongate openings 18 are cut in the sheet with a suitable routing tool 70 (step 3).
- This step is completed (step 4) by squaring off the ends of the openings.
- the required lengths of extrusion 116 are cut from a longer piece and pushed through opening 18, as previously described (step 5).
- the LED packages 130 are now attached to the extrusion using clips 50, with the flexible circuit ribbon 40 already in place or attached subsequently (step 6).
- the arrangement is ready for power connection (step 7).
- a suitable saddle element 80 is depicted in position in Figure 10. It has feet 82 glued to the rear of panel 12 and a linking web 83 shaped to bridge the rearwardly projecting circuit ribbon 40.
- FIG 11 illustrates another alternative form of extrusion 216.
- This form is generally similar to the extrusion of Figure 2, and is placed in the panel 212 in the same way, but to create different optical effects, the cylindrical portion 220 is not solid but instead tubular by virtue of a longitudinal cavity 60.
- the LEDs 234 are positioned closer to the cylindrical portion and to the cavity by a general shortening of the width of the extrusion: indeed the LEDs are located so as to protrude slightly above the actual location of opening 218 in panel 212. This arrangement is found to produce varied, optical effects in the viewing of the strips or lines of light.
- Figure 12 is a squatter modification 316 of the extrusion 216 of Figure 11.
- like parts are indicated by like numerals preceded by a "3".
- ribs 228 have merged into respective rectangular shoulders 110 that engage the top surface of panel 12.
- the domed top surface 88 merges into shoulders 110.
- Flanges 229 are of more uniform thickness but have a less pronounced and more chamfered return lip. Indeed, the finger pressure needed to insert and withdraw the LEDs is now reduced and the retentive force is sufficient to maintain the LEDs in place but easily overcome by pulling out the LEDs. (That is, a press fit rather than the snap fit mentioned earlier for the embodiment of Figure 2). It will be seen in Figures 11 and 12 how, in these embodiments, the internal pressure of the LEDs on the inside faces of flanges enhances the engagement of the extrusion with the panel 12.
- Figure 12 depicts another variation 416 of the extrusion of Figure 11.
- the inner side of the extrusion is generally similar, but the outer side is solid, ie. there is no cavity 60, and of a more protruding higher domed shape 417 in cross- section.
- Figure 14 is an alternative arrangement of the second aspect of the invention.
- the pcb or circuit ribbon 540 is used to anchor the LED packages 530 to a support structure (not shown) via spaced U-shaped clips 500.
- the extrusion 516 is not supported in an opening of a plate but instead the clips 500 are fastened to the support structure, which may be, eg, a backing plate or any other suitable surface, and the extrusion 516 is carried by the line of LED packages by virtue of the engagement of the LED packages 530 in longitudinally extending recess 526 with latching lips 525.
- extrusions 516 are arranged about and fixed to the backing plate or other suitable surface to form a sign or display assembly.
- the illustrated "A" of Figure 1 can be provided, but in a manner outstanding from the surface rather than being seated in and protruding from cover panel 12.
- This arrangement is another suitable substitute for neon tube technology in signs and displays.
- FIG. 15 A variation of the embodiment of Figure 14 is depicted in Figure 15.
- Clips 500', or a continuous extrusion of similar cross-section, are fixed internally, eg. by adhesive, to the floor or rear face 605 of a sign canister 600.
- Sign canister 600 may typically be closed by a translucent cover 602 that is thus backlit by the LEDs 534', themselves fixed along a T-edge 510 of ribbon 540'.
- the sign canister may well be an elongate letter or other character channel.
- Figures 16 and 17 depict a further embodiment that incorporates elements of the embodiments of Figures 11 , 14 and 8.
- the translucent light dispersive body or extrusion 716 in this case is substantially hollow, and thereby highly flexible, by virtue of two longitudinally extending cavities 760, 762 separated by a web 764.
- Cavity 760 is within the outer domed portion 720, while cavity 762 includes a smaller segment defining a recess 726 that seats LED packages 730, and a segment 763 large enough to embrace circuit ribbon 740.
- Ribbon 740 sits upright in a slot 774 defined along the floor of cavity 762 by a pair of ribs 775.
- the LEDs 734 fit firmly in a longitudinally extending arcuate-section groove 736 in the wall of recess 726 defined by web 764, directly opposite slot 774.
- the flexible extrusion 716 is attached to a backing plate or other support surface 712, in a manner similar to the embodiment of Figure 14, by a series of spaced moulded rectangular U-shaped clips 700.
- Clips 700 have return tabs 702 that engage complementary longitudinal grooves or slots 704 along the outsides of extrusion 716 just below web 764.
- the cross-web 706 of each clip 700 has a countersunk aperture 708 by which a screw 710 is employed to fasten the clip to a backing plate or other support surface 712.
- extrusion 716 is fitted with either a closure end cap or a coupling piece by which ribbon 740 is electrically coupled to another ribbon or to a suitable circuit connector.
- Figures 16 and 17 also illustrate useful alternative modifications for boosting the current supply to a length of ribbon: respectively a booster electrical current lead 780 or a double (face-to-face) circuit ribbon assembly of two ribbons 785.
- 500', 700 are substituted by a continuous fastening channel, eg. typically of similar cross-section to the clips.
