Definitions

  • the present invention relates to a laminated vehicle glazing, especially to a laminated vehicle glazing incorporating at least one electrical device.
  • Vehicles for example cars and buses, have a number of window openings in their bodywork into which glazings may be fitted; the glazings include windscreens, rear window glazings, side window glazings and roof glazings.
  • the windscreen is a laminated glazing (i.e. having two plies of glazing material joined together by a ply of interlayer material extending between them) for safety reasons, and the remainder of the glazings are usually toughened glass (although laminated side window glazings and roof glazings are becoming increasingly popular in vehicles).
  • WO 2004/009349 Al describes one example of such a glazing. It discloses a laminated vehicle glazing panel which includes light emitting diodes ("LEDs" - electrical devices) within the laminate.
  • the LEDs are typically provided on a circuit board, which is incorporated into the laminate, and may be used as indicia to convey information such as the speed of the vehicle into which the glazing panel is fitted. It would be desirable to be able to provide electrical devices over a greater surface area of a glazing than that covered when a circuit board is used, and where the electrical devices include at least one LED, to increase the functionality of the LEDs.
  • EP 1 655 999 Al describes one way in which electronic components (electrical devices) can be electrically attached to a substrate of any surface area. It discloses laying a wire according to a pre-determined pattern onto a substrate using an ultrasonic welding head. The wire and/or the substrate are provided with a plastic layer to enable an ultrasonic weld to be created between the two. Contact areas, which are areas of densely packed wire, are provided on the substrate in readiness for electronic components to be placed onto, and electrically connected to, them. When laid singly, the wire used is probably not noticeable to the human eye. However when densely laid (i.e.
  • the wire is tightly weaved) to form a number of contact areas, the wire will be visible and unsightly to the human eye - an important factor when considering the overall aesthetics of a vehicle and the demands placed by vehicle manufacturers on glazing manufacturers. It would thus be desirable to be able to provide a vehicle glazing which utilises the benefits of the prior art, but which also allows electrical devices to be placed over substantially the entire surface area of the glazing with a seemingly invisible electrical connection to them.
  • the present invention provides in a first aspect a laminated vehicle glazing comprising two panes of glazing material joined together by a ply of interlayer material which extends between them, and a plurality of individual electrical devices provided on a surface of the ply of interlayer material, each electrical device comprising an electrical contact area, and being electrically connected to a power source by electrical connection means provided over the contact area.
  • the individual electrical devices are independent from one another, i.e. each may exist in isolation, and each device thus requires its own electrical connection.
  • the electrical connection means is provided "over" the contact area of an electrical device, it is meant that the contact area is located between the ply of interlayer material and the electrical connection means. Provision of such a glazing means that any number of electrical devices may be included within the glazing (limited only by the dimensions of the glazing itself).
  • the manner of connection of the electrical connection means to each device furthermore means that it is effectively invisible to a human eye.
  • the panes of glazing material may be panes of glass, preferably soda-lime-silica glass, which may be clear or body-tinted, or they may be panes of a rigid plastics material such as polycarbonate.
  • the two panes may be made of the same material or one may be glass and one may be plastic.
  • the panes of glazing material are used in a thickness between 1 and 10 mm, preferably between 1.5 and 6 mm.
  • the ply of interlayer material may be a flexible plastics material, which may be clear or body-tinted.
  • Suitable interlayer materials include polyvinyl chloride (“PVC”), polyurethane (“PU”), ethyl vinyl acetate (“EVA”), polyethylene terephthalate (“PET”) and polyvinyl butyral (“PVB”), the most common choice for lamination being PVB, typically used in 0.76 mm thickness, although 0.38 mm thickness is also used.
  • An electrical device may be any device which requires electrical energy to perform its function and which has dimensions making it suitable for inclusion within a laminate, for example it may include one or more LEDs, a temperature sensor, a light sensor, a fingerprint sensor, a capacitive switch/sensor, and optical switch and the like.
  • At least one electrical device is an LED unit, which further comprises an LED.
  • All the electrical devices present within the laminate may be LED units, in which case, the glazing may provide a lighting function for a vehicle into which it may be fitted, for example interior lighting or ambient lighting.
  • An LED may have a thickness of less than 1 mm, typically around 0.8 mm, and a length and width each of around 3.5 mm - dimensions which are compatible with inclusion in a laminate.
  • the LED may be conductively attached to the electrical contact area.
  • the LED unit may comprise two electrical contact areas, to each of which the LED may be attached. This may typically be the case where an LED is solely provided with an area for electrical connection on its base, i.e. the normal surface on which the LED rests.
  • the or both contact areas are preferably made of a conductive material, such as copper or gold, having a thickness of less than 100 ⁇ m, preferably less than 60 ⁇ m and usually around 35 ⁇ m.
  • the or both contact areas may be provided on a substrate, which may additionally be comprised in the LED unit.
  • the substrate is preferably a flexible material, typically a polymeric material such as polyimide or polyester, which may be transparent or body-tinted (e.g.
  • the substrate may have a thickness of less than 100 ⁇ m, preferably between 20 and 80 ⁇ m and further preferably between 25 and 50 ⁇ m.
  • An LED may be electrically adhered to the one or both contact areas using suitable attachment means, such as solder or conductive glue.
  • the electrical contact area may be in the form of a metallic wing (most often two metallic wings) which is comprised in, and projects outwardly from, the LED itself, i.e. the LED is provided with an area for electrical connection which protrudes outwardly from its base.
  • the one or both metallic wings may be made of a highly conductive material such as copper or gold, and may have a thickness of less than 100 ⁇ m, preferably less than 60 ⁇ m and usually around 35 ⁇ m.
  • the individual electrical devices may advantageously be arranged on the surface of the ply of interlayer material in a random manner, such that there is no discernible pattern. Especially where the devices are LED units, this may be useful in achieving a "stellar" lighting effect - when powered the LEDs resemble stars in the night sky.
  • the electrical connection means comprises a conductive wire, connected between a pair of electrically conductive busbars provided within the glazing.
  • Busbars are typically made from thin (less than 0.2 mm thick, usually 0.1 mm thick) strips of conductive metal, for example copper, or from printed and fired silver-based conductive inks, or they may be made from a thermoplastic material in which particles of a conductive material are dispersed.
  • Busbars are usually located adjacent two opposing edges in a glazing as longitudinal strips. Some variation in the design of busbars is known, for example a busbar adjacent one edge of a glazing may extend around a corner of the glazing and adjacent another edge to allow convenient connection of both busbars to a power source. Such variations are within the scope of the present invention.
  • the resistance of the conductive wire is preferably in the range of 1 to 10 ⁇ m "1 , further preferably from 2 to 8 ⁇ m 1 and most preferably from 2.5 to 6 ⁇ m "1 .
  • the wire may be made of copper or other such suitable malleable, conductive material, and may have a diameter of 50 to 75 ⁇ m, such that it is effectively invisible to the human eye. Only a single strand of wire may need to be laid over an electrical contact area in order to establish an electrical connection to an electrical device, creating a seemingly invisible connection.
  • An electrical contact area usually has an upper surface and a lower surface, and the conductive wire may be electrically attached to the upper surface. This may be achieved using any suitable attachment means such as solder or conductive glue.
  • the conductive wire may electrically connect one electrical device to at least one other electrical device, and two or more electrical devices may be sequentially connected by a single conductive wire.
  • the pathway followed by the wire between successive electrical devices may be straight or it may be curved, allowing full flexibility in terms of the relative locations of the electrical devices.
  • the conductive wire is ultrasonically bonded to the ply of interlayer material in a surface region between two electrical devices and between an electrical device and a busbar.
  • the conductive wire may be attached to a surface of the ply of interlayer material (the same surface on which the electrical devices and the busbars are located).
  • the conductive wire may advantageously be provided with an insulating sheath, which means the wire can be deposited along a pathway which loops and crosses itself without causing a short circuit when powered is supplied to it.
  • the sheath may be black in colour.
  • the wire When insulated, the wire may be attached to an electrical contact area (and a busbar) using solder, preferably a low- melting point solder (having a melting point typically less than 150 0 C) to avoid the appearance of burn marks on the substrate.
  • solder preferably a low- melting point solder (having a melting point typically less than 150 0 C) to avoid the appearance of burn marks on the substrate.
  • the heat of soldering melts the insulating sheath at the point where electrical connection is required to the wire.
  • the wire When the wire is without insulation, it may be attached to an electrical contact area (and a busbar) using conductive glue.
  • the electrical connection means e.g. a conductive wire
  • the electrical connection means is sequentially connected to at least a first device, followed by a second device and then a third device (and between a pair of busbars to complete an electrical circuit).
  • three or more electrical devices may be connected in parallel.
  • three electrical devices may be connected in series forming a "series triplet" and there may a plurality of series triplets connected in parallel. Each series triplet may be supplied with a voltage of between 12 and 15 V.
  • a method of manufacturing a laminated vehicle glazing as described above comprising positioning a plurality of individual electrical devices on a surface of a ply of interlayer material, each device comprising an electrical contact area, electrically connecting each electrical device to a power source by providing electrical connection means over the contact area, and interleaving the ply of interlayer material between two panes of glazing material.
  • the resultant laminate structure is typically subjected to elevated temperature and pressure conditions in an autoclave, as is known in the art.
  • at least one electrical device is an LED unit which further comprises an LED.
  • the plurality of LED units may be pre-prepared in readiness for positioning on the ply of interlayer material.
  • the pre-preparation may involve initially providing a substrate with two contact areas made of a conductive material and subsequently conductively adhering an LED to the contact areas.
  • Each electrical device may be positioned in a random manner on the surface of the ply of interlayer material.
  • the devices may be positioned one at a time, or a number of devices may be positioned at the same time.
  • Preferably positioning of each electrical device on the surface of the ply of interlayer material is automated to enable efficiency. Further preferably the automated positioning is performed using a robot which places each electrical device on the surface of the ply of interlayer material according to a preprogrammed pattern.
