  • Said character defining means is preferably arranged to define a single character.
  • Said character defining means is preferably arranged to define a character against a background.
  • Said character defining means is preferably arranged to define a character by the character and background being visually contrasting when the illumination means is in use.
  • the background itself may be illuminated in use, with the character being relatively unilluminated. In a preferred embodiment, however, the character is illuminated in use and the background is relatively unilluminated.
  • Said character defining means is preferably arranged to allow light transmission through a character-shaped region arranged to define a character.
  • a relatively opaque region preferably surrounds the character-shaped region.
  • Said character-shaped region may be defined by means of a character-shaped opening in a first panel member.
  • Said first panel member is preferably associated with, suitably by being in face-to-face contact with, a second panel member.
  • Said second panel member is preferably arranged to transmit light, at least in a region on which said character-shaped region is superimposed.
  • Said second panel is preferably arranged inwardly of the first panel.
  • Said first panel preferably defines an outermost element of the sign element.
  • Said first and second panel members are preferably secured to one another, preferably by adhesive means.
  • Said integral illumination means preferably comprises a multiplicity of illumination elements.
  • Said illumination elements are arranged to define the character defined by said character defining means.
  • Said illumination elements are preferably light emitting diodes (LEDs).
  • Said integral illumination means is preferably arranged inwardly of the character defining means.
  • Said integral power supply means preferably comprises a battery.
  • Said battery is preferably re-chargeable.
  • Re-charging means is preferably provided for re-charging the battery.
  • Said re-charging means preferably includes a solar panel arranged to convert light to electricity for charging the battery.
  • Sensing means is preferably provided for sensing the ambient light level. Said sensing means is preferably arranged to allow power to be supplied to the illumination means when the ambient light level falls below a predetermined level. A manually operable switch means may also be provided for arming the sign element.
  • a control means for example, a printed circuit board is preferably provided and said illumination means and/or said power supply means and/or said sensing means and/or said manually operable switch means are in electrical contact therewith.
  • Said sign element is preferably a self-contained unit.
  • Said element preferably comprises a casing.
  • Said casing is preferably a watertight unit.
  • Said integral illumination means and said power supply means are preferably arranged within the casing.
  • An outer wall of the casing is preferably defined, at least in part, by said character defining means.
  • the character defining means comprises a first panel as described above, said first panel is preferably a component of said outer wall.
  • the character defining means comprises first and second panels secured to one another, this arrangement may be a component of said outer wall.
  • said first panel or the arrangement comprising secured together first and second panels includes co-operation means for co-operating with other parts of the casing.
  • Said co-operation means may comprise a stepped arrangement.
  • Said sign element preferably includes securement means for securing the element to a surface.
  • Said securement means is preferably associated with a lower surface of the element.
  • Said securement means is preferably arranged to be wholly concealed when the element is secured to a surface.
  • Said securement means preferably comprises an adhesive means, for example in the form of a double-sided adhesive material such as adhesive tape.
  • the invention extends to a sign comprising a plurality of sign element of the type described above.
  • Said sign elements of said sign are preferably juxtaposed.
  • the invention further extends to a method of constructing a sign comprising securing a sign element which comprises character defining means, an integral illumination means and an integral power supply means, to a surface.
  • the sign element 2 comprises a rectangular casing 4 having a stepped peripheral rim 6.
  • a re-chargeable battery (not shown) is secured, for example by means of an adhesive, to an upwardly facing surface of a lower wall 8 of the casing.
  • a printed circuit board 10 is provided within the casing and is seated in a recess (not shown) defined in the casing.
  • the printed circuit board is arranged to be powered by the battery.
  • An array 12 of light emitting diodes is provided above the printed circuit board.
  • the array 12 comprises a multiplicity of LEDs arranged to define an alphanumeric character. For example, in the element 2 shown in the figures, the LEDs are arranged to define the letter "A". The LEDs are arranged to direct light upwardly.
  • the casing 4 is closed by means of an upper member 14.
  • the member 14 comprises a smoked Perspex (Trade Mark) panel 16 and a white opaque plastics panel 18 which are bonded to one another in face-to-face contact.
  • the panels 16, 18 are arranged to define a stepped arrangement which co-operates with the stepped peripheral rim 6 so that the upper member 14 and casing 4 can readily be secured to one another in a watertight manner.
  • the smoked panel 16 is a planar rectangular panel.
  • the opaque panel 18 is rectangular and generally planar, except that an opening 20, arranged in the shape of an alphanumeric character (for example the letter "A” in the figures), is defined therein.
  • an alphanumeric character for example the letter "A” in the figures
  • a generally oval-shaped part 22, made of white opaque plastics material is bonded to an upper surface 24 of the smoked panel 16.
  • some alphanumeric characters can be defined by providing an opening in the panel 18 whereas others (e.g. the letters A, B, D, O, P, Q and R; and the numerals 0, 4, 6, 8 and 9) will require additional appropriately shaped parts to be bonded to smoked panel 16.
  • the upper member 14 also incorporates a solar cell 26 which is arranged to re-charge the battery.
  • a light level sensing device (not shown) is associated with the element 2.
  • the device is arranged to sense when the ambient light level falls below a predetermined level and to cause the element 2 to operate automatically in this event.
  • the element 2 is provided with a layer of double-sided adhesive tape (not shown) on its lower surface 28.
  • a sign comprising a plurality of sign elements 2 of the type described above may be assembled, for example outside a shop, simply by securing selected elements to a planar surface using the double-sided adhesive tape provided on the elements.
  • a sign comprising a plurality of sign elements 2 could be mounted on a free-standing and/or portable unit. When assembled each element of the sign operates as described below.
  • the solar cell During daylight hours, the solar cell generates an electric current which re-charges the battery of the sign element.
  • the light sensing device communicates this fact to the printed circuit board 10 which, accordingly, allows current to flow to the LEDs which, therefore, emit light.
  • the emitted light is transmitted through the smoked panel 16 and through the opening(s) defined in the opaque panel 18 and, accordingly, the alphanumeric character defined by the shape of the opening(s) appears as an illuminated character.
  • the sign elements may be made of any desired size. In a preferred embodiment the elements have a height of about 15 cm, a width of about 10 cm and a depth of about 2 cm.
