Patents Act 1990 COMPLETE SPECIFICATION INNOVATION PATENT Applicant: H.P.M. INDUSTRIES PTY LTD Invention Title: A GROUND LIGHT DEVICE The following statement is a full description of this invention, including the best method of performing it known to us: 2 A GROUND LIGHT DEVICE ct Field of the Invention c-I CI 5 The present invention relates to a ground light device suitable for illuminating a ground portion.
00 C Background of the Invention 1O 0 It is known to provide a ground light device which I includes an LED, a rechargeable power source for supplying CI power to the LED, and solar panels for supplying a recharge current to the rechargeable power source. The light device is configured such that the light device is relatively small and of a suitable shape and size to locate in a recess formed in the ground.
Such light devices are especially suitable for illuminating portions of a path.
Summary of the Invention In accordance with an aspect of the present invention, there is provided a ground light device comprising: at least one solar panel having a window portion through which light is able to pass; a light source disposed coplanar with or below the at least one solar panel; a translucent portion associated with the window portion such that light emitted by the light source passes through the window portion and the translucent portion and is thereby diffused by the translucent portion; and means for causing the light source to emit light; the ground light device being arranged to receive a rechargeable power source arranged to supply electrical power to the light source and to receive a recharge current from the at least one solar panel; and H:\jnelson\keep\speci\Innovation\P60276 A GROUND LIGHT DEVICE innov.doc 22/03/2006 3 the at least one solar panel and the translucent portion being disposed substantially in the same plane.
In this way, by disposing the at least one solar panel and C- 5 the translucent portion in the same plane, it is possible to provide a ground light device which has a relatively 00 low profile.
The light source may be disposed immediately adjacent the 10 translucent portion.
INO
i In one arrangement, the at least one solar panel includes an aperture and the translucent portion is disposed on the at least one solar panel so as to cover the aperture.
With this arrangement, the light source may be disposed in or immediately adjacent the aperture.
The ground light device may further comprise an annular portion and a base portion, the annular portion and the base portion at least partially defining an enclosure for receiving operative components of the ground light device.
The annular portion may define an aperture through which the at least one solar panel is visible.
The ground light device may further comprise a transparent panel, which may be formed of glass or plastics material, the transparent panel being disposed between the at least one solar panel and the annular portion.
The translucent portion may be formed on the transparent panel as a frosted portion.
In one arrangement, the translucent portion is integrally formed with the at least one solar panel.
Preferably, the light source comprises at least one LED.
H:\jnelson\keep\speci\Innovation\P60276 A GROUND LIGHT DEVICE innov.doc 22/03/2006 4 O Brief Description of the Drawings The present invention will now be described, by way of example only, with reference to the accompanying drawings, cl 5 in which: Figure 1 is a diagrammatic perspective view of a 00 ground light device in accordance with an embodiment of the present invention; and Figure 2 is a schematic circuit diagram which \1 0 illustrates an example circuit configuration for the light Sdevice shown in Figure 1.
Referring to the drawings, there is shown a ground light device 10 which includes an annular portion 12 and a base portion 14, the annular portion 12 and the base portion 14 defining an enclosure for receiving operative components of the ground light device 10. The annular portion 12 defines an aperture 16 through which light passes during use.
The ground light device 10 also includes solar panels 18 disposed in the enclosure adjacent the aperture 16 such that the solar panels 18 are visible through the aperture 16. In this example, a transparent panel, which may be formed of glass or plastics material, is disposed between the solar panels 18 and the annular portion 12 so as to provide a degree of protection for the solar panels 18.
Generally centrally of the solar panels 18 is formed an aperture 20, the aperture 20 being covered by a translucent portion 22. In this example, the translucent portion 22 is formed on the transparent panel as a frosted portion, although it will be understood that the translucent portion 22 may take other forms, such as a translucent patch disposed on the solar panels 18 above the aperture H:\jnelson\keep\speci\Innovation\P60276 A GROUND LIGHT DEVICE irmnnov.doc 22/03/2006
NO
Disposed in the enclosure adjacent the aperture 20 and beneath the translucent portion 22 is a light source, in tthis example in the form of at least one LED 24.
5 It will be understood that the translucent portion 22 serves to cause light from the LED 24 to diffuse and 00 thereby create a more pleasing visual effect.
It will also be understood that although the above example 10 includes an aperture 20 covered by a translucent portion
INO
S22, other arrangements are possible. For example, the C-i solar panels 18 may include an integral transparent portion to which is applied a translucent portion, or the solar panels 18 may include an integrally formed translucent portion.
It will also be understood that in order to provide a ground light device 10 which has a relatively low profile, the solar panels 18 and the translucent portion 22 are disposed substantially in the same plane or in planes which are immediately adjacent to each other. The profile of the ground light device may be further enhanced by disposing the light source below and immediately adjacent the translucent portion 22. In order to achieve this, the LED(s) 24 may be disposed in or immediately adjacent the aperture Although in this example the light source is in the form of at least one LED 24, it will be understood that other light sources may be used including incandescent bulbs, although light sources in the form of LEDs are preferred because LEDs require much less power than incandescent bulbs.
An example circuit 30 for use with the ground light device is shown in Figure 2.
H:\jnelson\keep\speci\Innovation\P60276 A GROUND LIGHT DEVICE innov.doc 22/03/2006 6 The circuit 30 includes a control unit 32 for controlling and coordinating operations in the ground light device tand rechargeable batteries 34.
C- 5 The control unit 32 is arranged to cause the LED 24 to emit light when electrical power is supplied to the 00 control unit 32 from the rechargeable batteries 34. The C-i control unit 32 may be arranged to cooperate with the control unit 32 so as to prevent transfer of electrical 10 power to the light emitting device in daytime and to INO Stransfer electrical power to the light emitting device at c- nighttime. For this purpose, a light dependent resistor 36 may be included in the light device 10 so as to cause an electrical current to flow to the LED when the light below a predetermined intensity shines on the light dependent resistor. However, it will be understood that other light sensing arrangements are envisaged, including phototransistors, and so on.
The ground light device 10 may also be provided with a switch (not shown) arranged to enable a user to selectively activate or deactivate illumination of the light emitting device 24.
Modifications and variations as would be apparent to a skilled addressee are deemed to be within the scope of the present invention.
