NZ 796348 A WIRELESS CONTROLLED STRING LIGHT DEVICE Related Applications This application is a divisional of New Zealand Patent Application No. 739186, the entire contents of which is orated herein by reference.

Field of the Invention The invention relates to a wireless controlled string light device and, more specifically but not exclusively, a Christmas wireless controlled string light device controlled by a Bluetooth-enabled mobile device.

Background of the Invention It is known to provide decorative string lights which typically play a significant part in many different e decorative displays. Though previously typically used during Christmas and on Christmas trees, it is now common to use decorative string lights as part of various festive celebrations through the year for both inside and outside displays.

The gradual development over the years in technology has produced a more user-friendly and safer string light. String lights were originally produced using mains e incandescent bulbs, then ssed to extra safe low voltage bulbs, then to LED bulbs to Wifi enabled lights, then Bluetooth-enabled extra safe low voltage LED string lights.

Bluetooth technology has been around for many years and there are existing products available. It is proposed to provide a decorative LED string light that can be controlled manually or by using Bluetooth technology (as opposed to Wifi or infrared technology).

The applicant has fied limitations with existing string light products. More specifically, decorative string lights are often placed in locations that are not easily accessible or the ller is not in a ient position once installed. The applicant has determined it would be advantageous to provide an alternative method for controlling the tive string lights in addition to manual control. It is therefore suggested that Bluetooth technology be orated directly into the same g as the plugpack transformer that converts the mains AC voltage to extra safe low voltage power (DC) which operate the string lights. This would allow the user to either manually control the string lights via a push button or using Bluetooth-enabled devices such as, but not limited to smartphones and tablets (via an App).

Examples of the ion seek to provide an improved wireless controlled string light device which eliminates or at least ameliorates disadvantages of previous string light products.

Brief Description of the Drawings The ion is bed, by way of non-limiting example only, with nce to the accompanying drawings, in which: Figure 1 shows a wireless controlled string light device diagrammatically, in accordance with an example of the present invention.

Figure 2 shows a rear view of a ck of the wireless controlled string light device of Figure 1; Figure 3 shows a side view of the plugpack of Figure 2; and Figure 4 shows an underside of the plugpack of Figures 2 and 3.

Detailed Description With reference to Figure 1, there is shown a string light device which incorporates oth technology directly into the same housing as the plugpack transformer which converts the mains AC voltage to extra safe low voltage power (DC) which es the string . Advantageously, this allows the user to either manually control the string lights via a push button or using Bluetooth-enabled devices such as smartphones and tablets. Figure 1 also shows that a solar panel and/or batteries may be used as a power supply for the string light.

More specifically, with reference to Figure 1, there is provided a wirelessly controlled string light device 10, ing a string light 12 having a plurality of LED lights 14, and a controller unit 16 electrically connected to the string light 12 for controlling nation of the string light 12. The controller unit 16 has Bluetooth connection functionality for receiving illumination commands from a wirelessly connected Bluetooth device (not shown). The controller unit 16 has rigidly mounted on the controller unit electrical pins 18 (see Figures 3 and 4) for connection to a supply of electricity such that the controller unit 16 is in the form of a plugpack. Accordingly, Bluetooth logy is incorporated directly into the mains plugpack (transformer) body which provides safe extra low voltage supply to the user-detachable decorative string lights. The lights are connected via common DC power line connectors/jacks. ageously, the main benefits of having the plug in the casing of the controller unit 16 include that: 1. It avoids messy and entangled cords, which obviously gets worse with length of cables; 2. Better product ility/safety as it avoids chafing or damage to the cord as there is none; 3. If a cord is used there is a greater likelihood of the plug pins being strained in the socket if the casing cannot rest on anything, so casing weight on the cord pulls the plug pins down causing poor contact or for the plug to fall out g the power or in worst case causing a hot spot and safety concern. This may be avoided if the plug point is close to the floor or near a table top but this may not always be the case; and 4. Avoids animals chewing or children pulling on the dangerous high voltage cord, only SELV power is exposed if a cord is damaged so it is safer.

The controller unit 16 includes a transformer for transforming the supply of electricity into safety extra low voltage electrical supply for the string light 12.

With reference to Figure 2, the controller unit 16 may include a manual control 20 for controlling nation of the string light 12. The manual control 20 may be arranged for controlling selection between a plurality of lighting modes of illumination of the string light 12. A range of lighting modes are listed on the rear of the controller unit 16 shown in Figure 2 as follows: 1. ON 2. COMBINATION 3. WAVE 4. ALTERNATING . GLOW 6. RUNNING FLASH 7. FADE 8. TWINKLE 9. G.

The manual l 20 may be in the form of a button 22 for manually cycling through said plurality of lighting modes.

With reference to Figure 1, there are shown on the hand side of the representation three atives including a first alternative where the string light device includes a linear string light, a second alternative wherein the string light includes branched string lights, and a final alternative in which the string light device includes extended linear string lights connected in . The string lights 12 may be detachable from the controller unit 16 so that the alternatives depicted in Figure 1 can be used interchangeably. With the branched string lights in which the string light device es a plurality of string lights 12, the controller unit 16 may be able to control illumination of each of the string lights 12 separately.

The string light device 10 may include a motion and/or sound sensor for detecting motion and/or sound whereby the controller unit 16 controls illumination of the string light 12 accordingly. The motion and/or sound sensor may be fitted to the controller unit 16.

Alternatively, the controller unit 16 may be ed with connectors to extend the range/position of external sensors or to potentially use existing Bluetooth connectivity for s. Existing string lights may use the mobile device to sense sounds via the microphone on the mobile device and then adjust the light display by Bluetooth. This system would e that the mobile device be in the range of the Bluetooth modules controlling the festive lights which usually means a range of around 10 meters, depending on other factors. The applicant has fied that as people will often want to move around with their smartphones, it is not ideal to use the sensors on the mobile Bluetooth device for this purpose.

Further distinctions of examples of the present invention over existing string light ements are discussed in the points below: 1. The Bluetooth technology is incorporated directly into the mains plugpack (transformer) body which provides safe extra low voltage supply to the user able decorative string lights. Lights are connected via common DC power line connectors/jacks.

The transformer/plugpack will include a manual override button but with the added feature of Bluetooth. 2. Examples may provide a portable set of low voltage llable LED string lights separated from the power source rather than an individual Bluetooth controllable mains voltage LED bulb ( or separated group of bulbs) 3. In an example, the proposed Bluetooth module may be incorporated into the mains plugpack body, which still includes a manual override button. Existing products have a Bluetooth module attached directly to the string lights and not directly into the transformer (plugpack). Separating the Bluetooth module from the strings lights allows any damaged lights to be easily and cheaply replaced without having to replace the Bluetooth module and then having to reset/pair or ram the Bluetooth device. It is also more cost ive as you house all the electronics in one body. 4. It is often the case that in other Bluetooth designs there is no manual override and everything is controlled via the Bluetooth module itself.

. In other designs, Bluetooth is used to control a separate device such as a speaker(s) which is connected to a string of lights for effect. The Bluetooth does not control the lights, only the r. Examples of the present invention do not require speakers and are able to control the lights by changing colours (if applicable) of the lights directly. Examples may also be able to l the sequence of how LEDs flash, or stay on or off, or on timer. 6. It is also possible to e in the t invention the additional following technology, if required, such as motion or sound sensing technology so that the lights will respond differently to changing external stimuli. 7. It is also possible to include a daylight sensor or a sensing circuit (solar t), if required, to control when the string lights turn on or off automatically. 8. It is also possible to substitute the transformer/plugpack with a solar panel and battery incorporating Bluetooth, if required, to power the string lights for places that have no power or installations that are hard to maintain. 9. It is also possible to allow a plurality of string lights to be connected into the body of the Bluetooth plugpack (rather than into wire hanging off plug pack like octopus arms) to create a branching effect of string lights or as an extension onto the existing string lights to create an even longer string. A plugged (weather protected) positive/negative power tor would be required at each string end to make the join if extending the string light.

. The controller casing is an all-in-one (fully integrated) unit with the mains plug encased with the Bluetooth, ormer and string light controller. The unit may be connected to a wall-mounted mains electricity supply socket. 11. es of the invention use a manual control on the casing as well as oth functionality. 12. Rather than controlling each light bulb individually, examples of the present invention control each string light segment. 13. In a proposed design multiple string lights are connected to the casing of the plug pack.
