Description

1 AUSTRALIA Patents Act 1990 MORT BAY TRADERS PTY LTD COMPLETE SPECIFICATION INNOVATION PATENT Invention Title: Solar powered rope light The following statement is a full description of this invention including the best method of performing it known to us:- 2 Technical Field Described embodiments relate generally to lighting assemblies, systems and kits for solar-powered rope lighting. 5 Background External lighting can sometimes be difficult, cumbersome and/or expensive to locate and most external lighting systems rely on receiving power from a mains power supply. 10 It is desired to address or ameliorate one or more shortcomings or disadvantages associated with existing external lighting arrangements, or to at least provide a useful alternative thereto. 15 Summary Some embodiments relate to a lighting assembly, comprising: a housing that houses: a solar panel to generate current from light, one or more rechargeable batteries and a control unit; 20 an electrical cable coupled to the housing and electrically coupled to the one or more rechargeable batteries; and at least one rope light mechanically and electrically coupled to the electrical cable to receive power from the one or more rechargeable batteries, each rope light having a series of light emitting diode (LED) lights arranged electrically in parallel and 25 encapsulated within a substantially solid transparent plastic cord; wherein the assembly relies on current generated by the solar panel to charge the one or more rechargeable batteries and is free of reliance on an external power source. Some embodiments relate to a solar powered rope light assembly or kit, comprising: 30 conversion means to generate electrical current from sunlight; energy storage means to store energy resulting from generated electrical current; and at least one rope light coupled or coupleable to the energy storage means to receive stored energy therefrom, each rope light having a series of LED lights arranged 35 electrically in parallel and encapsulated within a substantially solid transparent plastic cord.
3 Some embodiments relate to a kit comprising: a housing that houses: a solar panel to generate current from light, one or more rechargeable batteries and a control unit; an electrical cable coupled to the housing and electrically coupled to the one or 5 more rechargeable batteries; and at least one rope light mechanically and electrically coupleable to the electrical cable to receive power from the one or more rechargeable batteries, each rope light having a series of LED lights arranged electrically in parallel and encapsulated within a substantially solid transparent plastic cord; 10 wherein the kit relies on current generated by the solar panel to charge the one or more rechargeable batteries and is free of reliance on an external power source. The at least one rope light may have a male connector on one end and a mating female connector on an opposite end, where the electrical cable is arranged to mate with one of 15 the male and female connectors. The assembly may further comprise an insulating plug to sealingly mate with and cover a male or female connector at an exposed end of the at least one rope light. Each rope light may comprise about 15 to 20 LED lights per metre. 20 The housing may comprise a toggle component operable to cause the control unit to light the LED lights of the at least one rope light in one or more timing and/or flashing patterns. 25 The assembly or kit may comprise multiple rope lights, optionally each having different colours. The assembly or kit may further comprise an ambient light sensor arranged on the housing to sense ambient light impinging on the housing. The control unit may be 30 responsive to output of the light sensor to turn on the at least one rope light when low light is detected and to turn off the at least one rope light when day light is detected. Brief Description of the Drawings 35 Embodiments are described in further detail below, by way of example, with reference to the accompanying drawing in which: 4 Figure 1 is a schematic representation of a lighting assembly. Detailed Description 5 Described embodiments relate generally to solar-powered rope light assemblies, systems and kits. Such assemblies, systems and kits are intended for use outside, where sunlight can be received during the day and where lighting may be provided for aesthetic or functional purposes during the evening or night. 10 Referring to Figure 1, there is shown a lighting assembly 100 according to some embodiments. Lighting assembly 100 comprises a housing 110 that has energy conversion means, such as a solar panel 112 extending substantially across one face of the housing 110. The solar panel 112 comprises solar cells arranged to generate current in response to impinging sunlight, as is known in the art. 15 Housing 110 comprises a control unit 130 including at least one signal processor and a memory, for example on a printed circuit board (PCB) positioned inside the housing 110. The PCB may comprise further electronic components such as are appropriate for carrying out the functions described herein. Housing 110 further comprises energy 20 storage means, such as a rechargeable power source such as one, two, three or more rechargeable batteries 125 electrically coupled to control module 130 to supply power to one or more segments 145 of rope lights. In some embodiments, 3, 4, 5, 6 or more rechargeable AA batteries may be provided, depending on the number of rope light segments 145 to be powered and the length of time for which they are desired to be lit. 25 Housing 110 further comprises a light sensor 120, preferably positioned adjacent the solar panel 112 on the front face of the housing 110, in order to best sense ambient light conditions, but optionally positioned elsewhere on the housing 1 10, such as on a side or underside. Light sensor 120 is preferably coupled to control unit 130 in order to 30 provide signals thereto indicative of ambient light levels, in response to which control unit 130 compares the light levels to pre-set threshold levels and may selectively control the supply of power to one or more rope lights 145 coupled to receive power from batteries 125 via an electrical cable 140. 35 Electrical cable 140 is mechanically and electrically coupled to housing 110 in order to supply current from batteries 125 to one or more rope light segments 145 electrically 5 and mechanically connected to electrical cable 140 via mating female (150) and male (160) electrical and mechanical connectors. Each rope light segment 145 has a male connector 160 at one end thereof and a female 5 connector 150 at an opposite end thereof, so that multiple rope light segments 145 can be concatenated end-to-end and all of them receive current from batteries 125. Each rope light segment 145 of roughly six metres in length has about 15 to 20 (e.g. 18) LED light sources per metre, yielding roughly between 90 and 120 LED lights for each rope light segment 145. Each rope light segment 145 comprises a solid extruded flexible 10 plastic cord. Different lengths of rope light 145 may be used and different numbers of LED lights per metre of the rope light may be employed, as desired. Each rope light segment 145 comprises a generally solid transparent plastic cord within which the LED lights are encapsulated and arranged electrically in parallel. The 15 flexible plastic cord is formed by an extrusion process, with the series of LED lights being encapsulated within the cord during the extrusion process. The flexible plastic cord is waterproof and the male and female connectors 160, 150 are arranged also to be watertight when properly coupled to each other or to an end plug 165, so that the one or more lengths of rope light 145 can be arranged around a wet garden or even within a 20 body of water, such as a pond, pool or fountain. In order to provide appropriate short circuit protection at the last exposed connector at a free end of the one or more rope light segments 145, a sealing and insulating plug 165 is manually fitted to the exposed male or female end connector 160, 150 and forms part of the assembly 100 (either as assembled or in kit form). 25 Housing 110 has a manual switch, for example in the form of a button 115 to allow a user of the light assembly 100 to switch it between a non-operational mode and an operational mode. In the non-operational mode, the solar panel 112 may still charge the batteries 125, but the control unit 130 does not automatically turn on the rope lights 30 145 when the ambient light is sensed by control unit 130 and sensor 120 to have reached the pre-set low light threshold level. In the operational mode, control unit 130 automatically turns on the rope lights 145 once the sensed light level (as indicated by signals from light sensor 120) passes a preset threshold level. The control unit 130 in the operational mode also turns the rope lights 145 off when the light level increases 35 (i.e. because of daybreak) above the threshold level. The threshold levels for turning on and off the rope lights may be different.
6 Additionally, a function switch or button may be provided on housing 110, for example at the back, to allow a user to toggle the timing and/or sequence or pattern of the LED lights and the rope lights 145. For example, when the user first presses the toggle button, the controller 130 may cause power to be supplied to the LED lights in each 5 rope light 145 in a simple flashing on/off mode. When the user presses the toggle button again, the control unit 130 may cause the LED lights in each rope light 145 to be selectively displayed in a stored sequence or pattern. Further pressing of the toggle button by a user may shift the lighting display mode to yet another stored timing and/or display pattern, and so on through a number of different pre-stored modes (e.g. 8), after 10 which further pressing of the toggle button returns the mode to a simple always on (i.e. non-patterned) mode. The rechargeable batteries 125 may have a charge capacity of around 1500 mAh to 2000 mAh (milliampere-hours). Such capacity will allow 3 or 4 rope light segments 15 145 to be coupled end-to-end and may be lit for a duration of about 6 to 8 hours. Each rope light may have only a single colour of LED lights or it may comprise multiple different coloured LED lights in the same rope light segment 145. Optionally, for single colour rope lights 145, segments of different colours can be connected end-to end. 20 The solar panel 112 may provide around 5.5 volts/250 milliamps (mA), for example, or may have a larger or more efficient array to provide greater voltage/current. Lighting assembly 100 further comprises a mounting means such as a ground stake 170 25 and/or a wall or bracket mounting component to mount the housing 110 in a position where it can receive optimal levels of sunlight. Housing 110 has suitable coupling components mountable on its rear face to allow it to be mounted by a ground stake 170 or suitable wall or bracket mounts. 30 Each rope light segment 145 has encapsulated therein suitable wiring, connections and/or components to facilitate conduction of current to the encapsulated LED junctions. In some embodiments, the female connector 150 has a floating screw cap or coupling sleeve 155 attached thereto for enabling a manually screw-threaded sealing connection with the male connector 160. Coupling sleeve 155 is held about an outside 35 part of the female connector 150 by a retention flange so as to be freely rotatable for threaded engagement to a thread on the male connector 160 or end plug 165. In other 7 embodiments, this floating screw-threaded coupling sleeve 155 may be provided on the male connection 160 instead to mate with corresponding thread on the female connector 150 or end plug 165. 5 In a kit form, the lighting assembly 100 may be sold with the housing 110 and electrical cable 140 connected but with a single disconnected rope light segment 145 and separate mounting components. The user can then couple the rope light segment 145 (and possibly more than one if separately purchased) to the electrical cable 140 and then choose and affix the appropriate mounting component to mount the housing 110 so that 10 the solar array 112 is suitably positioned. Throughout this specification the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element, integer or step, or group of elements, integers or steps, but not the exclusion of any other element, 15 integer or step, or group of elements, integers or steps. Any discussion of documents, acts, materials, devices, articles or the like which has been included in the present specification is not to be taken as an admission that any or all of these matters form part of the prior art base or were common general knowledge 20 in the field relevant to the present invention as it existed before the priority date of each claim of this application.
