`
`TECHNICAL FIELD
`
`The present invention relates to solar poWered lights and
`more particularly but not exclusively to solar poWered lights
`that produce a light of varying colour.
`
`20
`
`BACKGROUND OF THE INVENTION
`
`Light devices that employ light emitting diode (LED) sys
`tems to produce a variable colour are knoWn. Examples are
`described in US. Pat. Nos. 6,459,919, 6,608,458, 6,150,774
`and 6,016,038. It is also knoWn to have “garden lights” that
`are solar poWered. For example such garden lights include a
`body providing a spike that is driven into a ground surface. At
`the upper end of the spike there is mounted a diffuser sur
`rounding a lamp, With the lamp being driven by rechargeable
`batteries and a solar cell.
`The abovementioned lighting apparatus have a number of
`disadvantages including dif?culty in adjusting the various
`lighting functions and not producing a uniform desired colour
`When required to do so.
`
`25
`
`30
`
`35
`
`OBJECT OF THE INVENTION
`
`40
`
`It is the object of the present invention to overcome or
`substantially ameliorate at least one of the above disadvan
`tages.
`
`SUMMARY OF THE INVENTION
`
`45
`
`There is disclosed herein a lighting device to produce light
`of varying colour, said device including:
`a body;
`a lens mounted on the body and generally enclosing a
`chamber having an upper rim surrounding a top opening, and
`a bottom region;
`a re?ector mounted in the bottom region;
`a cap assembly including securing means to releasably
`engage the rim so that the cap assembly can be selectively

`
`DETAILED DESCRIPTION OF THE PREFERRED
`EMBODIMENTS
`
`In FIGS. 1 to 9 of the accompanying draWings there is
`schematically depicted a lighting device 10. The device 10 of
`this embodiment is con?gured as a “garden ligh ”. 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 ?xed to it a
`“bayonet” ?tting 17 that engages a shaft 18 ?xed to the upper
`end of the post 12. The ?tting 17 includes an “L” shaped slot
`19 through Which the shaft 18 passes to secure the lens assem
`bly 14 to the upper end of the post 12.
`The chamber 16 includes a loWer portion 20 Within Which
`there is mounted an arcuate re?ector 21 that is concave.
`The lens 15 has a rim 22 surrounding the upper opening 23
`ofthe lens 15.
`Removably attached to the rim 22 is a cap assembly 24. The
`assembly 24 includes a cover 25 ?xed 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 con?guration
`so as to provide the device 10 With a generally vertical lon
`gitudinal axis 35.
`The base 26 has radially inWard projecting ?ange segments
`36 that engage With radially outWard extending ?ange seg
`ments 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 FIG. 5, the ?ange segments 37 have end abutment
`portions 38 against Which these segments 36 engage When the
`assembly 24 is secured to the lens 15.
`As can be noted from FIG. 6, 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 recti?er circuit, and a light circuit.
`The poWer supply circuit comprises a solar cell 30 con
`nected 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 con?gurations may be utilised Without departing
`from the spirit and scope of the invention.
`When the solar cell 30 is exposed to su?icient 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 100
`kQ ?rst resistor 41. The ?rst resistor 41 is connected in series
`With a second, light-dependent resistor 42. The second resis
`tor 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 suf
`?cient light, the value of the second resistor 42 decreases.
`Accordingly the resistor 42 alloWs the lighting device to
`operate only When there is insu?icient light, ie night.
`The boost-up circuit is connected to the light operated
`circuit, in parallel With the ?rst resistor 41 and the second,
`light-dependent resistor 42. A ?rst circuit node 43 is de?ned
`betWeen the sWitch 40 and the ?rst resistor 41. Connected to
`55
`the node 43, is an emitter terminal of a ?rst triode 44. A
`collector terminal of the ?rst triode 44 is connected in series
`With a 100 kQ third resistor 45. The third resistor 45 is then
`connected to a point betWeen the ?rst resistor 41 and the
`second resistor 42.
`A 220 kQ fourth resistor 46 is connected to node 43 across
`the emitter and base terminals of the ?rst triode 44. In parallel
`With the fourth resistor 46, and also connected across the
`emitter and base terminals of the ?rst triode 44, is a 4.7 nF ?rst
`capacitor 48. Further connected to node 43, across the emitter
`and base terminals of the ?rst triode 44 and in parallel With
`each of the fourth resistor 46 and the ?rst capacitor 48, is a 100

`pH inductor 49 in series With a l nF second capacitor 50. The
`second capacitor is then connected to the base terminal of the
`?rst triode 44.
`A 20 k9 ?fth resistor 51 is connected across the base and
`collector terminals of the ?rst 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 capaci
`tor 50 is the collector terminal of a third triode 53. The base
`terminal of the third triode 53 is connected via an intermedi
`ary circuit to the collector terminal of the second triode 52.
`The intermediary circuit consists of a 2.4 kQ fourth resistor
`54 in parallel With a l nF 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 recti?er 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 33
`HF 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 de?ned 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 recti?er
`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 embodiments shoWn, the IC 61 is a 16-pin, three
`colour LED IC for controlling ?rst, 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, 71.
`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 corres
