6.Jan. 2005 20:37 Wallinston-Dummer Sydney No.8244 P. 4 m -2- C] First draft 24-12-04 F LIGHT EMITTING BASE ND The present invention relates to stands for the placement and display of objects and, more particularly to c n 5 stands forming a base adapted to illuminate an object o placed upon it.

In o BACKGfROUD For many people it is desirable to have available at the bedside during the night a glass of water. Groping for such a glass in the dark is a hit and miss affair since the glass is rarely in precisely the same place. Yet to turn on a light just for this purpose is uncomfortable at least, since bedside lights usually are sufficiently bright for reading and other fully awake activities. Yet again when the need arises during the night to visit the bathroom, turning on the light is similarly unpleasant.

It is an object of the present invention to address or at least ameliorate some of the above disadvantages or to offer a useful alternative.

DET AZI DESCRIPTION OF PZRD EMODIfNMTS In a first preferred embodiment of a light emitting base 10 for the support of an at least partially transparent container 11 according to the invention and as shown in figures I and 2, a support structure 12 is shaped so as to form a base portion 13 comprising a perimeter frame 14 with a raised central support portion 15. Support structure 12 may have any convenient shape such as circular as shown in figure 1 or square or hexagonal for example.

Support structure 12 may be formed from any suitable material, such as from pressed metal including for example stainless steel and aluminium, or may be injection moulded from a suitable polymeric material. Preferably base portion 13 is provided with a non-marking and non-slip layer of 6.Jan, 2005 20:38 8.Jan 209620:38 Wall intgon-Dummer Sydney o84 .1 No 8244 P I I material 16 on the underside 17 of base portion 13 as shown in figure 2. Base portion 13 may further be provided with a

IND

O layer of dense material (not shown) to add weight and stability to the base.

o 5 Central support portion 15 is adapted to support a o sheet of transparent material 18 such as glass or of a o polymeric material. Supported within base portion 13 and cibelow central support portion 15 as may be seen in f igure 2, is an electronic circuit board 19 provided with a plurality of upwardly projecting light sources 20 arranged in a predetermined pattern. Light sources 20 are preferably light emitting diodes but may comprise any substantially point-like light sources and could for example include the light emitting ends of fiber optic cables drawing light from a central light source. In an alternative form broader light sources such as miniature neon lights can be used. In a further form ~strip lighting can be utilised.

Central support portion 15 is provided with a plurality of holes 21 coincident with the pattern of light sources and adapted to receive them so as to bring their upper surfaces approximately flush with the upper surface of central support portion 15. Light emitting sources may be set in any desired pattern ahd may for example include a pattern of concentric rings of sources.

In at least one preferred form of the invention a decorative layer of material (not shown) such as for i 6.Jan, 2005 20:39 Wallington-Dummer Sydney No. 8244 P 12 0- 0 c example an embossed or patterned metallic foil, may be interposed between the upper surface of central support

IO

oportion 15 and the underside of transparent material 18.

This decorative material if installed is provided with a 5 matching pattern of holes to that pattern of the holes 0 0 oprovided in central support portion ci t In this first preferred embodiment, light sources 0 C receive power from the mains power circuit via a transformer 22 such as a plug-in transformer typically used for small, low-powered appliances. Power switching is effected by an on/off switch 23 which may either be located interposed at some convenient location along the length of power supply lead 24 as shown in figure 1 or mounted within frame 14 as shown in figure 2. Alternatively, a lightsensitive switch may be incorporated in the control circuit, so that power is switched on to the light sources whenever the location of the base is sufficiently darkened.

In at least one preferred embodiment support structure 12 when formed of a conductive material is provided with a touch sensitive circuit so as to react to the touch of the fingers to trigger the cycling of the power circuit incorporated in the base portion between a power "off" state and a power "on" state. Such cycling may incorporate intermediate light intensity levels such that a first touch for example switches the light sources from the power off state to a first low level of intensity, a second touch to

IIII-

\O

o a maximum back to power off. Such touch sensitive control circuits are well known in the lighting industry.

o 5 Where individual light sources such as diodes are Sused, all may be switched to the same state, that is, o either on or off or to the same intensity level, in unison.

Ci Alternatively, a logic circuit may be included in the printed circuit board, so programmed that when power is supplied to the circuit board selected groups of diodes cycle sequentially between emitting and non-emitting states. Such cycling may further include provision for gradual increases and decreases in light intensity.

In a second preferred embodiment of the present invention, light sources may be supplied with power from replaceable batteries or from rechargeable batteries.

In a further preferred embodiment of the present invention as shown in figure 3 in which like elements are numbered alike but with the addition of 100, transparent sheet 118 is combined with a substrate layer of solar collector cells 125 adapted to recharge batteries 126 during periods of natural or artificial light. In this embodiment the solar cell layer is provided with perforations or holes 121 through which the light of the light emitting sources 120 is projected.

U III I I l llill I II 6Jaft. 2005 20:39 Wail in ton-Dummer Sydney No ,8244 P 14 in -12 In a further preferred embodiment shown in figure 4, power is made available from a computer USB port. In this

\O

o embodiment, the perimeter frame 214 is provided with a USB socket 223 so as to allow the base 200 to be connected to a computer (not shown) via a standard USB cable 224. In this o embodiment light emitting sources of the base may come on ci Swhenever the computer is activated, or may be controlled by ^C a switch mounted in frame 214.

In stil1 another preferred embodiment, the central support portion 15 may be arranged to support the sheet of transparent material 18 only at the periphery, thus allowing a concave form of the central region of support portion The base of any of the above described embodiments may be used to support any of a range of containers but is primarily adapted for the support of a transparent glass 11 filled with water as shown in figure 1. The effect of the light sources projecting upwardly through the transparent sheet of material transforms the appearance of the glass into a column of subdued refracted and reflected light, making the glass easily and attractively discernable in a darkened room without causing discomfort to a person just awakened. Depending on the number and intensity of the light sources used, the base may project sufficient, though subdued light, into its surroundings to enable a person to move about the room in which the base and glass are placed.

The base may also be used with decorative effect for the support of other containers, such as for example glass vases of flowers or other glass and transparent artifacts.

The above describes only some embodiments of the present invention and modifications, obvious to those skilled in the art, can be made thereto without departing from the scope and spirit of the present invention. Thus for example, the light source could be a peripheral cold cathode ring. Also a hologram or holographic design could be incorporated in the support portion for example.
