Definitions

  • This invention relates to a lighting system which enables elongate lengths of illumination to be provided for a wide range of decorative, safety and other applications.
  • Linear lighting systems used hitherto have generally been in the form of extruded tubing of a resilient, translucent or transparent material, e.g. extruded plastics tubing.
  • the tubing is illuminated by a series of bulbs connected together by electric wiring to form an elongate lighting string which is threaded through the tubing to provide an internal illumination means therefor.
  • the tubular strip is then located where desired to provide an elongate lighting system for decorative or safety purposes.
  • a length of such illuminated tubing may be provided in a non-slip nosing across the front edges of the steps of a staircase.
  • the lighting system may be used in flooring systems e.g. at a junction between different types of flooring or floor covering. It may be provided as a decorative embellishment e.g. on walls, or display systems, or along bar pelmets, wherever a decorative pencil-line of light is desired.
  • the lighting system may follow nonlinear paths, e.g. wound as a shallow spiral around columns or pillars.
  • a length of the wiring incorporating the spaced apart illuminating elements does not provide a standard predictable length thereof owing to the flexibility of the wire connectors of the illuminating device which are soldered to the intermediate lengths of connecting wiring. Over a relatively long stretch there can be a very significant expansion or contraction of a supplied length of the illumination wiring resulting in a discrepancy with the length over which the illumination is required to extend.
  • the illumination wiring which is usually stored on a roll, is relatively brittle owing to the soldered wire connectors associated with the illuminating devices, which are free to bend.
  • US-4,654,765 teaches an elongate lighting assembly which can be produced from insulated strips having electrical conductors thereon.
  • the light bulbs are connected in parallel between the voltage supply lines.
  • This specification is concerned with a method of mounting the bulbs on the strips in an easily replaceable fashion.
  • This system therefore utilizes an entirely parallel arrangement of the light bulbs on a set of similar length strips so that the full supply voltage is applied to each light bulb, which in some applications prevents the use of relatively low voltage bulbs.
  • US-4,607,317 discloses connectors for connecting together elongate lighting circuits to form a linear strip.
  • each module is of the same length and requires to be cut at specific marks in order to tailor the lighting assembly to specific requirements. This limits the particular lengths which can be accommodated and makes for a relatively cumbersome procedure on site.
  • US-3,755,663 discloses a display device comprising miniature lamps connected in series to form substrings which are coupled in parallel between a pair of parallel supply conductors. This assembly is then slidably inserted in a transparent flexible tube. The tube can be cut as desired but only between the substrings. This again limits the particular lengths which can be accommodated and the overall system is relatively cumbersome to assemble and to adapt to specific requirements on site.
  • EP-A-0,336,601 describes a lighting system comprising a set of voltage compatible printed circuit boards of different finite lengths, each having a series connected set of illuminating devices connected in parallel between voltage supply lines provided on the strips.
  • One strip may have a single illuminating device and a compensating resistor connected together in series with the series connection being connected in parallel across the voltage supply lines.
  • the invention seeks to provide improvements in or modifications of the lighting system illustrated in EP-A-0,336,601 to provide improved performance over relatively long length, and/or to provide additional control or constructional modifications of the lighting system for more flexible practical operations thereof.
  • the invention provides a lighting system in accordance with Claim 1.
  • the invention also provides a lighting system in accordance with Claim 8.
  • the invention further provides a lighting system in accordance with Claim 10.
  • Each of said strips may be in the form of a printed circuit board.
  • Connector means may be provided, the connector means comprising at least one connector member for location between a pair of adjacent strips and having means for resiliently gripping each of said juxtaposed ends of the strips, and means for making an electrical connection between the adjacent ends of said elongate electrical lighting circuits associated with the strips.
  • a lighting system may include a voltage supply connecting means for supplying a voltage to said continuous electrical lighting circuit at one or both ends thereof, said voltage supply connecting means comprising a terminal portion adapted to be resiliently gripped by a connector member as aforesaid which is to be resiliently engaged with one end of one of said strips, and having electrical connecting means for making an electrical connection between the electrical connection means of that connector member and a voltage supply.
  • a lighting system may include flexible connecting means for electrically connecting a pair of strips which can be set at different angular positions with respect to one another, said flexible connecting means comprising connector portions each adapted to be resiliently gripped by a respective one of a pair of said connector members which are to be resiliently engaged with adjacent ends of said pair of strips, respectively; flexible means connecting said connector portion; and electrical connecting means for making an electrical connection between the electrical connection means of said pair of connector members.
  • a lighting system according to the invention may further include an elongate tubular container having a translucent or transparent wall or wall portion, for receiving said plurality of elongate strips when connected by said connector means.
  • Said tubular container may have a removably mounted wall section extending along its length.
  • Said tubular container may comprise an elongate base channel-section strip, and an elongate, translucent cover strip which can be removably engaged with the base strip to close the channel-section thereof.
  • Interengageable snap fastening means may be provided on said base strip and said cover strip.
  • Said base strip may be made of a resilient electrically insulating material.
  • the base strip may be metallic and relatively rigid, with an internal lining of an electrically insulating material provided to isolate said lighting circuit from the metallic base strip.
  • a plurality of base strips and cooperating cover strips which can be secured together may be provided to form required lengths thereof.
  • Gasket means may be provided for effecting waterproof joints between adjacent base and cover strip combinations.
  • Figure 1 illustrates the lighting system of Figure 6 of EP-A-0,336,601 comprising a set of a number of different length, flexible, circuit boards on each of which the electric circuitry is arranged to provide a series connection between the lamp elements.
  • Each circuit board (65) has two voltage supply lines (67,68) and an electric line (69) connected in parallel across the voltage supply lines (67,68), which connects in series the lamps associated with that board and any compensating resistor.
  • the system illustrated in Fig. 1 comprises four different, finite lengths of circuit board, having circuitry for mounting six, five, four and one lamp, respectively, at regularly spaced positions (100).
  • an appropriate resistor is generally mounted at a position (101) in order to make all the circuit boards in the set voltage compatible with one another whereby the resistance of the series connected elements is the same for each circuit board of the set.
  • lamps or LEDs (60) of the same voltage rating are used throughout, although this is not essential.
  • appropriate resistors (66) are used to make all the circuit boards in the set voltage compatible with each other and with the desired supply voltage.
  • different sets of standard circuit boards can be provided having different spacings between the location positions of the lamps for any linear length of illumination constructed by coupling the appropriate number and size of circuit boards end to end using coupling elements described below. Examples of such spacings are 50 mm, 75 mm and 100 mm. However in other constructions irregular spacings may be selected for special effects.
  • Each coupling element (110) comprises an outer housing (111) comprising an upper part (112) and a lower part (113) snap fitted together.
  • Each housing part (112,113) comprises an oblong tray-like member having upstanding peripheral wall portions with resilient pegs (114) provided on abutting edges of the wall portions of the two housing parts (112,113) to engage in corresponding apertures in the opposite abutting edges to provide a snap connection means for the two housing parts, which are disposed in inverted positions with respect to one another.
  • the end walls of the housing parts (112,113) are recessed to provide an entry slot (115) for receiving end portions of two circuit boards to be joined end to end by the coupling element (110).
  • Three location formations (118) of oblong cross section are integrally formed between the dividing walls (116) and the longitudinal side walls of the parts (112,113) for engagement in centrally located recesses (119) in the connecting elements (117).
  • Each connecting element (117) has, at each end, a pair of resilient forks (120) for making electrical connections with the circuitry provided on the circuit boards (65).
  • a voltage supply connector element (1120) is provided for coupling to one end of a linear series of circuit boards (65) joined together by coupling elements (110).
  • the connector element (1120) includes a terminal portion provided by a short strip of circuit board (1121) having a circuit track arrangement, as illustrated in Fig. 14C, provided thereon.
  • the circuit track comprises a negative electric line (1122) and a positive electric line (1123) which has connector points (1124) for connection therein, e.g. by soldering, of a fuse (1125).
  • a supply cable (1126) has positive and negative feed wires (1127,1128) which are connected by soldering to positive and negative terminal connector points (1129,1130) on the circuit board (1121).
  • the free end portion of the circuit board (1121) is inserted into a slot (115) of a coupling element (110) located at the end of a circuit board (65) disposed at one end of the linear series thereof.
  • the outer pair of electrical connecting elements (117) of the coupling element make electrical contact with the positive and negative lines (1123,1122), on the circuit board (1121) to connect the supply voltage across the voltage supply lines (67,68) on the circuit board (65), to provide the voltage supply of the lighting system.
  • a flexible connecting device (130) for allowing the connection of adjacent circuit boards in a series thereof, which boards may be set at different angular positions relative to one another.
  • the device (130) comprises a pair of similar connector portions (131) made of a short strip of circuit board having a circuit provided thereon, as illustrated in Fig. 5C, consisting of three electric lines, i.e. positive line (132), a negative line (133) and a central line (134).
  • the connector portions (131) are joined by flexible jumper wires (136,137,138) which electrically connect the positive lines (132), the negative lines (133) and the central lines (134) on the connector portions (131).
  • Circuit board (65) can be cut to fit around each corner with the cut pieces then being coupled together using flexible connector devices (130). Firstly, coupling elements or devices (110) are engaged with the cut ends of the circuit board (65). Then, the connecting portions (131) of a connector device (130) are engaged in the open slots (115) of the respective coupling devices (110).
  • the flexible jumper wires allow the cut sections of the circuit boards (65) to be located along different sides of the aforesaid structure.
  • the voltage supply lines (67,68) of the two parts of the severed circuit board (65) are connected by the jumper wires (136,137) and the series connection lines (69) are connected by the jumper wire (138).
  • circuit boards (65) which fit precisely the lengths along each side of the rectangular structure without any need for cutting any of the circuit boards (65).
  • the same coupling devices (110) and flexible connector devices (130) are utilized at the corners, but in this arrangement the central jumper wire (138) is redundant in operation.
  • voltage supply connectors may be connected to both ends of the electrically coupled series of circuit boards (65) to maintain the voltage along the entire length of the system.
  • a set of calculation charts are preferably provided for each set of circuit boards for operation at a predetermined supply voltage and using illuminating devices of a predetermined operating voltage.
  • the charts give a concordance between the number of lamps required, at the preselected spacing therebetween, for any length as measured on site.
  • a further concordance chart then gives the required number of circuit boards of the different lengths in the set for that length in dependence on the number of lamps required.
  • the "series-parallel" arrangement is advantageous because the lamps required are of lower rated voltages so that a greatly reduced current flow, e.g. one quarter the current of a similar parallel arrangement, is present in operation of the system. This provides a safer system which is generally more compact because lower rated, and therefore smaller components, are needed.
  • a specific example of a practical system according to the invention is designed to operate at 24V (AC or DC) with lamps of 5V for a "series-parallel" arrangement, and a maximum current flow of 3 amps.
  • a lighting system according to the invention would normally be supplied as a kit comprising standard finite length of flexible circuit boards and coupling elements allowing any required linear length to be built up from these components.
  • the positioning of the lamps on the circuit boards, and the length of the coupling elements is such that, when a set of such boards are coupled in a linear series, the required predetermined spacing of the lamps along the entire linear length of the coupled boards is achieved.
  • further boards may be provided for an end of any coupled series to accommodate a voltage supply connecting element whilst still maintaining the required predetermined spacing relationship between the lamps along the entire length of any coupled series of circuit boards.
  • Each strip (65) may be, for example 50 cm long, 5 mm wide and 1 mm thick. Ten or twenty strips and copper tracking thereof can be formed side by side on a single substrate. A router may separate the individual strips leaving connecting pips therebetween. Alternatively no routing may be carried; instead the strips may be separated at a later stage by a multi-saw device. The lamps and resistors are then inserted on the upper sides of the strips with the terminal portions pushed through the strips to engage solder pads on the copper tracking formed on the underside of the strips. The terminals are cropped and soldered to those pads. The boards are then introduced into a defluxing bath where they are degreased and defluxed. They are blasted with lacquer or other insulating sealant in order to protect the copper tracking from oxidization. After the lacquer has dried the individual circuit boards are snapped apart and finished to remove the connecting pips or are separated by a multi-saw device.
  • FIGS 6A - 6F illustrate schematically an embodiment of the invention in the form of a lighting system comprising a set of printed circuit board elements of different finite lengths.

  • the positive and negative ring circuit voltage supply lines (200,201) are connected directly to the positive and negative voltage supply lines (67,68), respectively.
  • This can be achieved by using an additional coupling element fitted onto the terminal circuit board of the series and having fitted in its opposite receiving section a small circuit board element having the required electrical bridging circuits provided thereon.
  • Such an arrangement is illustrated in the embodiment of Figs. 8A - 8I.

If both the ring circuit lines (200,201) and the control line (201) are omitted, the embodiment of the invention still provides two separate lighting circuits which can be used for different circumstances or uses as mentioned above.
  • Figs. 8A - 8I comprises a lighting system comprising a set of different length circuit boards each having four separate light circuits (A - D) provided thereon.
