`
`Detailed Description of the Preferred Embodiments
`
`In Figures 1 to 9 of the accompanying drawings there is schematically depicted a
`
`lighting device 10. The device 10 of this embodiment is configured as a “garden light”.
`
`The device 10 includes a body 11 including a post 12 from the lower end from which
`
`there extends a spike 13. The spike 13 is driven into a ground surface so that the post 12
`
`is exposed above the ground surface.
`
`Attached to the upper end of the post 12 is a lens assembly 14. The lens
`
`assembly 14 includes a lens 15 that encompasses a chamber 16. The lower end of the
`
`lens 15 has fixed to it a “bayonet” fitting 17 that engages a shaft 18 fixed to the upper end
`
`of the post 12. The fitting 17 includes an “L” shaped slot 19 through which the shaft 18
`
`passes to secure the lens assembly 14 to the upper end of the post 12.
`
`The chamber 16 includes a lower portion 20 within which there is mounted an
`
`arcuate reflector 21 that is concave.
`
`The lens 15 has a um 22 surrounding the upper opening 23 of the lens 15.
`
`Removably attached to the rim 22 is a cap assembly 24. The assembly 24
`
`includes a cover 25 fixed to a base 26. The base 26 is located beneath the cover 25 and is
`
`shielded thereby. The base 26 and cover 25 encompass a chamber 27 within which there
`
`is a mounted moulding 28. The moulding 28 is provided with battery compartments 32.
`
`The components of the circuit 29 are located within the chamber 27, while the upper
`
`surface of the assembly 27 is provided with the solar cell 30. The cell 30 is exposed
`
`through a central rectangular aperture 31 of the cap 25.

`
`Mounted within the chamber 27 via battery compartments 32 are rechargeable
`batteries 33 which are used to energise three LEDs 34. The LEDs 34 when illuminated
`
`produce red, green and blue light.
`
`The cap assembly 24 is generally circular in configuration so as to provide the
`
`device 10 with a generally vertical longitudinal axis 35.
`
`The base 26 has radially inward projecting flange segments 36 that engage with
`
`radially outward extending flange segments 37 of the rim 22 to be secured thereto. By
`
`angular movement of the cap assembly 24 about the axis 35, the segments 36 and 37
`
`engage or disengage to secure or to release the assembly 24 with respect to the lens 15.
`
`As can be noted from Figure 5, the flange segments 27 have end abutment portions 38
`
`against which these segments 36 engage when the assembly 24 is secured to the lens 15.
`
`Mounted on the under surface of the base 26 is a second lens 38. Accordingly,
`
`the LEDs 34 when activated have their light preferably diffused by the lens 38 and then
`
`further diffused by the lens 15. This in particular aids in producing a more evenly
`
`coloured light when the LEDs 34 are activated.
`
`The circuit 29 powers and controls the lighting device 10 in accordance with an
`
`embodiment of this invention. The circuit 29 consists of a number of interconnected sub-
`
`circuits, including a power supply circuit, a light operated circuit, a boost-up circuit, a
`
`rectifier circuit, and a light circuit.
`
`The power supply circuit comprises a solar cell 30 connected in series to a
`
`forward biased diode 39, which is in turn connected to a positive terminal of a battery 33.
`
`A negative terminal of the battery 33 is then connected to the solar cell 30 to complete the
`
`power supply circuit.
`
`In this example, the diode 39 is a model number IN5817 Schottky
`
`diode and the battery comprises two rechargeable 1.2 volt battery cells.
`
`It will be
`
`apparent to a person skilled in the art that other diode and battery configurations may be
`
`utilised without departing from the spirit and scope of the invention.
`
`When the solar cell 30 is exposed to sufficient light, the solar cell converts some
`
`of the solar energy to electrical energy and creates a current that passes through the diode
`
`39 to charge the battery 33. Thus, during the day the solar cell 30 converts energy from
`
`the sun to charge the battery 33. The diode 39 prevents the battery 33 from expending
`
`any power on the solar cell 30.
`
`The power supply circuit is connected in parallel to the light operated circuit,
`
`which is connected across the terminals of the battery 33. The positive terminal of the
`
`battery 33 is connected to a switch 40, which is in turn connected to a 1001(0 first resistor
`
`41. The first resistor 41 is connected in series with a second, light-dependent resistor 42.
`
`The second resistor 42 connects to the negative terminal of the batteries 33 to complete

`
`the light operated circuit. The value of resistance of the second resistor 42 depends on the
`
`amount of light to which the second resistor 42 is exposed. When there is not much light,
`such as occurs during the night, the value of the second resistor 42 increases. During the
`
`daytime, when there is sufficient light, the value of the second resistor 42 decreases.
`
`Accordingly the resistor 42 allows the lighting device to operate only when there is
`
`insufficient light, ie night.
`
`The boost-up circuit is connected to the light operated circuit, in parallel with the
`
`first resistor 41 and the second, light—dependent resistor 42. A first circuit node 43 is
`defined between the switch 40 and the first resistor 41. Connected to the node 43, is an
`
`emitter terminal of a first
`
`triode 44. A collector terminal of the first triode 44 is
`
`connected in series with a IOOkQ third resistor 45. The third resistor 45 is then connected
`
`to a point between the first resistor 41 and the second resistor 42.
`
`A 220kfl fourth resistor 46 is connected to node 43 across the emitter and base
`
`terminals of the first triode 44.
`
`In parallel with the fourth resistor 46, and also connected
`
`across the emitter and base terminals of the first triode 44, is a 4.7nF first capacitor 48.
`
`Further connected to node 43, across the emitter and base terminals of the first triode 44
`and in parallel with each of the fourth resistor 46 and the first capacitor 48, is a IOOuH
`
`inductor 49 in series with a lnF second capacitor 50. The second capacitor is then
`
`connected to the base terminal of the first triode 44.
`
`A 20k!) fifih resistor 51 is connected across the base and collector terminals of
`
`the first triode 44. Connected across the terminals of the third resistor 45 are the collector
`
`and base terminals, respectively, of a second triode 52.
`
`'The emitter terminal of the
`
`second triode 52 is connected to the negative terminal of the batteries 33.
`
`Connected between the inductor 49 and the second capacitor 50 is the collector
`
`terminal of a third triode 53. The base terminal of the third triode 53 is connected via an
`
`intermediary circuit to the collector terminal of the second triode 52. The intermediary
`
`circuit consists of a 2.41m fourth resistor 54 in parallel with a lnF third capacitor 55. The
`
`emitter terminal of the third triode 53 is connected to the negative terminal of the battery
`
`33.
`
`Also connected between the inductor 49 and the second capacitor 50 is the
`
`rectifier circuit. A forward biased second diode 56 is connected to a point between the
`
`inductor 49 and the second capacitor 50, and then to a positive terminal of a 33uF fourth
`
`capacitor 57. The negative terminal of the fourth capacitor 57 is connected to the
`
`negative terminal of the battery 33. A second circuit node 58 is defined between the
`
`second diode 56 and the fourth capacitor 57. Connected in parallel with the fourth
`
`capacitor 57, between the second node 58 and the negative terminal of the battery 33 is a

`
`reverse biased 4.5V third diode 59. The second diode 56, the fourth capacitor 57 and the
`
`third diode 59 comprise the rectifier circuit. Further connected to the second circuit node
`
`58, in parallel with each of the capacitor 57 and the reverse diode 59, is a light circuit 60.
`
`The light circuit 60 contains an integrated circuit (IC) 61 for controlling lighting
`
`effects provided by the lighting device 10.
`
`In the embodiment shown, the IC 61 is a 16—
`
`pin, three colour LED IC for controlling first, second and third light emitting diodes
`
`(LEDs) 34A, 34B and 34C. Each of pins 1, 15 and 16 is connected in series to respective
`
`switches 69, 70, 60. Each of the switches 69, 70 and 71 is then connected to the negative
`
`terminal of the battery 33.
`
`In one embodiment, the switches 69, 70, 71 correspond to the
`
`LEDs 34A, 34B, and 34C to enable or disable a particular colour range.
`
`In another
`
`embodiment, the switches 69,70, 71 determine the frequency of a colour changing effect.
`
`In a further embodiment, the switches 69,70, 71 detennine the intensity of light emitted
`
`by each of the LEDs 34A, 34B, and 34C. Various combinations of the frequency and
`
`intensity of light are also possible. The switches 69, 70, 71 can be made accessible to a
`
`user to create custom lighting effects. Alternatively, the switches 69, 70, 71 are set
`
`according to a predetermined configuration and are not readily accessible by a user.
`
`Pin 4 of the IC 61 enables an optional pause function. In this embodiment, pin 4
`
`connects to a push button 65 that is, in turn, connected to the negative terminal of the
`
`batteries 33. Pin 3 of the IC 61 connects to the second circuit node 58.
`
`Connected to the second circuit node 58, and in parallel with one another, are the
`
`first second and third forward biased light emitting diodes (LEDs) 34A, 34B and 34C.
`
`The first LED 34A is connected in series with a sixth resistor 66 that is connected to pin
`
`13 of the IC 61. The second LED 34B is connected in series with a seventh resistor 67
`
`that is connected to pin 12 of the 1C 61. The third LED 34C is connected in series with an
`
`eighth resistor 68 that is connected to pin 11 of the IC 61.
`
`In this example, the first LED
`
`34A is blue, the second LED 34B is green and the third LED 34C is red.
`
`Pins 6 and 8 of the IC 61 are tied to one another via a ninth resistor 72, which in
`
`the embodiment shown is a ZOKQ resistor. The valve of the ninth resistor 71 determines
`
`the frequency of a colour change created by the IC 61. Accordingly, using different
`
`resistor valves for the ninth resistor 71 produces colour changes of different frequencies.
`
`Pin 9 of the IC 61 is tied to the negative terminal of the battery 33.
`
`During the day, the solar cell 30 charges the battery 33. The value of the second
`
`resistor 42 is low and, consequently, small amounts of current flow through the boost—up
`
`circuit, rectifier circuit and light circuit. As night falls, the amount of energy converted
`
`by the solar cell 30 decreases. The resistance of the second resistor 42 increases and more
`
`current flows into the boost-up circuit, rectifier circuit and light circuit. This activates the

`
`LEDs 34A, 34B, and 34C in the light circuit and the light device 10 produces a changing
`
`light effect.
`
`The integrated circuit 61 controls each of the first, second and third LEDs 34A,
`
`34B, and 34C to produce a changing light effect for the light device 10. The integrated
`
`circuit varies the frequency and intensity of light emitted by the LEDs 34A, 34B, and 34C
`
`to produce a constantly changing kaleidoscopic effect. The light device 10 displays a
`
`constantly changing lighting effect that cycles through the light spectrum by ramping up
`
`and ramping down the intensity of light displayed by the LEDs 34A, 34B, and 34C.
`Connecting the optional pause function ofpin 4 of the IC 61 to the push button
`
`65 enables a user to stop the changing light effect and maintain a constant colour. In this
`
`manner, a user can select a preferred colour for a lighting effect. The user observes the
`
`changing colour effect and when a desired colour is displayed, the user depresses the
`
`pause button 65.
`
`The colour displayed at the time that the button is pressed then remains on.
`Preferably, the circuit retains sufficient charge such that a user selected colour is retained
`
`during the day and is displayed again when the light is reactivated the following evening.
`
`In this manner, the user does not have to reselect a desired colour each night. To reinstate
`
`the changing light effect, the user presses the push button 65 again and the changing light
`
`effect resumes.
`
`In the emboiiiment shown in Fig. 9, the battery 33 powers the light circuit 60
`
`during the night to produce light of varying colours and the user can optionally select a
`
`desired colour by pushing the push button 65. A selected colour is retained by memory in
`
`the IC 61. The memory may be a switch. Whilst the battery is powering the light circuit
`
`60, the fourth capacitor 57 stores charge. As stated above, it is desirable for a selected
`
`colour to be retained and displayed on successive nights. As the battery 33 discharges,
`
`the output voltage of the battery 33 decreases. When the output voltage of the battery 33
`
`is less than the stored voltage of the capacitor 57, the capacitor 57 discharges. Due to the
`
`presence and arrangement of the diodes 56 and 59, the capacitor 57 discharges through
`
`the light circuit 60.
`
`The IC 61 preferably includes a cut-off circuit that is voltage dependent. As the
`
`capacitor 57 discharges, the voltage across the cut-off circuit decreases. Once the voltage
`
`across the cut-off circuit reaches a predetermined threshold value
