Field of the Invention
The present invention relates to electrical controllers, in particular to electrical controllers for use with decorative lights.
Background to the Invention
Decorative lights, such as mains-powered LED Christmas tree light strings are well known. An electrical controller is typically used to perform a voltage step down and to enable different decorative modes, such as constantly on, flashing or other cyclical illumination patterns to be produced. Mode selection may take place by cycling through the functions using a mode selection switch, independently of on-off control, with on-off control provided by interrupting the mains circuit supply.
It is desirable to increase flexibility in control of decorative lights, while maintaining low costs for the controller.

Brief Introduction to the Drawings
For a better understanding of the invention, and to show how embodiments of the same may be carried into effect, reference will now be made, by way of example, to the accompanying diagrammatic drawings in which: Figure 1 shows a perspective view of an electrical controller according to an example embodiment; and Figure 2 shows a method of using an electrical controller according to an example embodiment.
Description of Example Embodiments
Figure 1 shows an electrical controller 1 according to an example embodiment. The electrical controller 1 comprises a 3 pin mains (220V-240V, 50Hz) electrical supply input 20 and an electrical output 30 for connection to a decorative lighting element (not shown). The electrical controller 1 further comprises a housing 10, arranged to support the electrical supply input 20 on a side of the housing 10 and the electrical output 30 on an opposite side of the housing 10. The electrical controller 1 further comprises a control unit (not shown), arranged in the housing 10. The electrical controller 1 generally acts a transformer to step down the voltage from the electrical supply input 20 to a lower level at the electrical output, and further comprises a mode selector 40. The mode selector 40 is arranged on the housing 10 proximal the electrical output 30 and on a same side of the housing 10 as the electrical output 30. The mode selector 40 comprises a push button switch with an integrated LED. The mode selector 40 comprises the only means for a user to provide control inputs to the control unit.
The control unit comprises a mode generating chip supplemented by discrete components to provide mode setting capacity and a timer in the electrical controller 1.
In use, a user selects a mode using mode selector 40 by pressing the push button switch. Repeatedly pressing the push button switch cycles through modes. In use, different modes are recognisable to a user by operation of a decorative lighting element coupled to the electrical output 30. A change of a mode may be indicated to a user by a visual indicator of the mode selector 40, for example, the integrated LED may flash each time it is pressed. The modes may involve a timed interruption of supply to the electrical output, and reversing the polarity of supply, either alone or in combination, to produce a different visual effect from a decorative lighting element coupled to the electrical output 30.
A user starts a timer and the start of an on period for supply of electrical energy to the electrical output 30 by operating the mode selector 40. Pressing and holding the push button switch for longer than a predetermined period of time starts the timer at the start of an on period. The operation of the timer is indicated to a user by a visual indicator of the mode selector 40. In this embodiment the integrated LED is continuously illuminated or may flash repeatedly. With the timer in operation the electrical controller 1 is arranged to control an electrical output supply to electrical output 30 according to a on period/off period set according to a according to a daily, weekly or monthly schedule.
In the example embodiment described above, a short operation of the mode selector 40, for example pressing the push button switch for less than 3 seconds is determined by the control unit to be a user input for a change of operation mode. The duration of a short press input may be set on manufacture, for example at 3s, 4s, 5s, or more than 5s. A long operation of the mode selector 40, for example a long press of the push button switch, is determined by the electrical controller to be a user input for the start of timer operation, or alternatively if the timer is already running is determined by the electrical controller to be a user input for cancellation of timer operation.
The duration for the timer's on period, i.e. the period over which, in timer operation, electrical energy is supplied by the control unit to the electrical output, may be set on manufacture, for example 6 hours, 8 hours, 10 hours, or more than 10 hours. In example embodiments the part of the world and time of year at which the electrical controller are intended for use may be considered by the manufacturer in determining the duration of the timer's on period, for example by considering daylight hours and a typical duty cycle for decorative lighting elements or other electrical equipment to be coupled to the output of the electrical controller.
The electrical controller 1 is suitable for connection, at the electrical output 30, to a decorative lighting element comprising a LED string light. Typically this sort of decorative lighting element will comprise one or more LED branches wherein a LED branch comprises one or more LEDs. A plurality of LED branches may be arranged in parallel and/or in series and in this way, a LED string light may comprise 1 -1000 LEDs. A preferred duty cycle for Christmas LED string light may be obtained by using the timer to turn off the LED string light after a predetermined period of illumination. Use of a daily 8 hour/16 hour timer pattern as between on period and off period is preferred, in order to conveniently match the hours of activity around the Christmas period during a typical Northern hemisphere day time/night time at central European latitudes.
In the example embodiment of Figure 1, the electrical controller 1 comprises a 3 pin mains electrical supply input 20 for connection to a UK domestic mains electricity supply, but it is to be understood that this is for illustration only. Other example embodiments may be provided to comprise a 2 pin or a 3 pin mains electrical supply input suitable for 100V-250V and 50Hz-60Hz, according to national and/or local mains electrical supply and/or standards.
In still further example embodiments the electrical supply input 20 may comprise terminals for a battery pack, or a battery may be provided integrally with the electrical controller 1 to provide a source of power for the control unit and/or for delivery to the electrical output 30 under control of the control unit.
In the example embodiment of Figure 1, the electrical controller 1 comprises a housing 10, arranged to support an electrical supply input 20 on a side of the housing 10 and an electrical output 30 on an opposite side of the housing 10 but it is to be understood that this is for illustration only. Other example embodiments may comprise a housing 10, arranged to support an electrical supply input 20 on a side of the housing 10 and an electrical output 30 on another side of the housing 10, for example, an adjacent side of the housing 10, or the same side of the housing 10.
Figure 1 shows the mode selector 40 arranged on the housing 10 proximal the electrical output 30 and on the same side of the housing 10 as the electrical output 30. Other example embodiments may comprise a housing 10, arranged to support an electrical supply input 20 on a side of the housing 10 and an electrical output 30 on another side of the housing 10, for example, an adjacent side of the housing 10, or the same side of the housing 10.
Further possible modifications include variation to the mode selector 40. Although the mode selector 40 in the embodiment of Figure 1 comprises a push button switch with an integrated LED, other example embodiments may be provided to comprise a mode selector 40 comprising, for example, a toggle, rotary, reed, proximity, Hall-effect, rocker, magnetic, dip, slide, thumbwheel or keylock switch. In such example embodiments the mode selector 40 is suitably provided with a visual indicator comprising a separate passive and/or an active indicator, for example, a colour indicator, a light. Further, other example embodiments may be provided that comprise a switch that itself performs the function of a visual indicator, wherein the indicator is arranged in, on or near the switch itself.
Figure 2 shows a method of using an electrical controller according to an example embodiment.
At step S10, a user selects a mode of lighting a string light, for example, a comb mode, an in waves mode, a sequential mode, a slo-glo mode, a chasing/flash mode, a slow fade mode, a twinkle/flash mode or a steady on mode by using a mode selector. This operation is performed for example by short pressing a push button switch that operates at the mode selector. Once a mode has been selected, and with the timer inoperative, the electrical controller continues to operate indefinitely while connected to an electrical supply.
At step S20, the user starts a timer also by using the mode selector, for example by pressing and holding the same push button switch that was used to perform the mode selection step 810. The step S20 further comprises a visual indicator displaying visually to the user that the timer has started, for example an integrated LED in the mode selector is illuminated. In this example embodiment an integrated LED provided within the push button switch that operates as the mode selector is illuminated to indicate that the timer is operational. At the end of the timers on period, the electrical controller ceases to supply electrical energy to the electrical output, and thereafter resumes supply to the electrical output at the end of the timers off period.
While the timer is operational, and during the timer's on period, a user may further change the mode of lighting a string light, for example, a comb mode, an in waves mode, a sequential mode, a slo-glo mode, a chasing/flash mode, a slow fade mode, a twinkle/flash mode or a steady on mode by using a mode selector. This operation is performed, for example, by short pressing a push button switch that operates at the mode selector. Once a new mode has been selected, and with the timer operative, the electrical controller continues to operate while connected to an electrical supply and until the end of the timer's on period is reached.
Optionally, the user may stop and/or reset the timer by using the mode selector. For example, by performing the step of pressing and holding the push button switch the timer operation may be cancelled. This step may also include operation of the electrical controller such that a visual indicator indicates that the timer has stopped or reset. In the example embodiment described above, when the timer is has been cancelled so as not to be running the integrated LED in the push button switch is not illuminated by the electrical controller.
As set out above, electrical controllers according to the example embodiments provide an increase in the flexibility in control of decorative lights such an Christmas LED light string coupled thereto, while maintaining low costs for the electrical controller. A user may select a mode of a Christmas LED string light in a straightforward manner, only needing to manipulate a single push button switch on the controller to cycle through modes. Furthermore, a user's convenience is increased as once the desired mode is selected the same push button switch is used to start a timer. With the timer running the mode selection function of the push button switch is maintained, and cancelling the timer operation is also intuitively performed in the same manner as setting the time. Using the same mode selector to control and to indicate the operation of the timer is efficient in avoiding the need for additional moving mechanical components, and the associated costs in manufacturing a housing etc. to accommodate more than one switch or other input element/visual indicator. The timer operation itself improves user convenience, enables energy-saving and may extend the service life of the Christmas LED string light by turning off the Christmas LED string light after a predetermined period of illumination. The use of a daily 8 hour/16 hour timer pattern conveniently matches the hours of activity around the Christmas period during a typical Northern hemisphere day time/night time at central European latitudes.
