Description

[Technical field]

[0001] The present invention relates to a garden light control system and control method, and in particular to a system consisting of a number of garden lights and power supply cables between them using a power supply control box system, and in particular to a system capable of providing multi-function control for each garden light or a light group of garden lights, thereby allowing the garden lights to automatically execute the lighting mode previously selected by the user, thereby satisfying the demand for time-division and zone-division lighting in gardens. [Background technology]

[0002] Conventional lighting systems such as garden lights or outdoor lights are used to be installed at various positions in a garden and provide necessary lighting after sunset. For example, as shown in Patent Document 1 (U.S. Patent No. 7,632,159 (B2)), it mainly consists of a control box, a number of garden lights, and a power supply cable, and a number of garden lights are installed at various positions in the garden, respectively, and then each garden light is connected to the power supply cable, which is also connected to the control box. Thus, the control box outputs a voltage to each garden light through the power supply cable, and the control box controls the power supply or cutoff in an integrated manner, so that a number of garden lights can be turned on and off at the same time.

[0003] The basic control function of the conventional control box is a light sensor circuit that achieves a dusk to dawn (D / D) power supply control function (abbreviated as D / D function), so that when the light sensor circuit of the control box detects that it is pitch black, it outputs a voltage to each garden light through the power supply cable in an integrated manner, and lights up each garden light brightly at the same time to achieve the purpose of illumination. Meanwhile, after the light sensor circuit detects that it is dawn and the sun is beginning to shine, it immediately cuts off the power supply and turns off each garden light in a unified manner. In addition, the control box with advanced functions is provided with a set of timer circuits (Timer) to provide a unified turn-off time set by the user, for example, it may be set to turn off after 6 hours, so that the light sensor circuit can detect a signal at sunset, and the control box controls each garden light to be turned on simultaneously in an integrated manner, and immediately cuts off the power supply in an integrated manner after 6 hours has passed to turn off the light of all the garden lights, or uniformly sets the time to turn on and turn off the lights according to the timer circuit.

[0004] However, each garden light in the same control box cannot simultaneously select different light-off times or other lighting functions. In detail, the above-mentioned conventional garden light lighting system can only control the garden lights to be turned on or off in unison by receiving power from the same power supply cable through the detection of the light sensor circuit of the control box or the automatic control technology of the timer circuit, and the user cannot set a certain group of lights to be always brightly lit from sunset to dawn, or a certain group of lights to be turned off in advance after a certain time has passed. If the above function is to be achieved, theoretically, a control device (for example, see U.S. Patent Application Publication No. 2009 / 0195063(A1)) can be installed inside or outside each garden light, but this will make the garden light expensive, and each garden light will have to be managed individually, making the settings complicated, and it will not be possible to easily control the lighting time of each frame using the control box. Alternatively, two power supply cables may be connected to a single control box, one of which is a power supply loop circuit controlled through the above-mentioned optical sensor circuit, and the other is a power supply loop circuit controlled by the above-mentioned timer circuit. By connecting a large number of garden lights to each power supply cable in this way, some lights are always brightly lit from sunset to dawn, and some lights are turned off in advance after a certain period of time has passed. However, in this case, two power supply cables need to be buried in the garden when arranging the wiring, and if some garden lights are turned off at various times before dawn (for example, 9 p.m., midnight, and 3 a.m.), four power supply cables need to be arranged, which is economically disadvantageous for users, increases the installation cost, and makes the work process complicated.

[0005] Therefore, how to provide users with a number of garden lights connected to the same single power supply cable based on one power supply control box system and one power supply cable, without needing to add other power supply cables (power supply loop circuits) or implementing costly automatic control devices in the garden lights, but only through switching the selection switch inside or outside the garden light for each light, or selecting according to different connection legs plugged into the electrical connector, can realize that a certain group of lights (e.g., sidewalk lights) can continue to light from sunset to dawn, while a certain group of lights (e.g., lights for landscape lighting) can be turned off when it reaches the time point set in the control box, and realize low-cost time-division division and multi-lighting functions, is a novel technology that the present invention should break through.

[0006] As described in the prior art, the conventional garden light and outdoor light system uses a control box to control the on and off time of each garden light in a consistent manner in all areas, achieving the purpose of integrated lighting control. However, with the trend of modern people's living space uses becoming more and more diversified, there are different lighting demands for different outdoor spaces. For example, in key safety protection spaces, it is necessary to provide lighting until late at night or all night long, and in some spaces, it is possible to achieve energy saving effects by turning off or dimming the lights before midnight. The lights can be turned on when people or vehicles approach the roadway or sidewalk, and can be turned off or dimmed after the people or vehicles leave. In some areas, when it is necessary to provide landscape lighting or create an atmosphere, it is necessary to provide lights that automatically switch between different color temperatures and brightness according to the changes in time, temperature, and seasons, and the above conventional garden light and outdoor light control system may not be able to fulfill the role of meeting various demands.

[0013] Referring to the construction diagram of the garden light control system of the present invention shown in FIG. 1, the garden light control system includes a power supply control box system 10, a power source 20, a power supply cable 40 connected to the power supply control box system 10, and a number of garden lights 30 connected to the power supply cable 40, among which, the power supply control box system 10 is used to provide required power to the garden lights 30, and receives a day / night signal emitted from a light sensor circuit of a day / night sensing unit, and stops outputting power supply during the day and outputs a different time during the night by a timer circuit of one or a number of internal clock units. According to the band, it outputs power with different voltage attributes, including attributes such as positive and negative polarity exchange of the power supply voltage, modulation of the positive and negative polarity exchange frequency, or modulation of the positive and negative polarity duty cycle, and is used to provide required power to the garden light 30 connected via the power supply cable 40. The garden light 30 identifies the state of its voltage positive and negative polarity, positive and negative polarity exchange frequency, positive and negative polarity duty cycle, etc., and performs a pre-agreed operation (lighting function) in comparison with that selected by the function setting switch of the garden light 30 according to the state or state exchange form, thereby achieving functions such as time-division and section-division lighting.

[0014] The power supply control box system 10 changes the attribute contents and exchange frequency of the voltage of the power provided, generally according to the complexity and simplicity of the system function and the communication protocol. Take a simple two-division time division function as an example. The first time division period is the time from sunset to the first set time point set by the timer circuit of the internal clock unit, and the second time division period is the time from the end of the first time division period to dawn. The power supply control box system 10 outputs power of positive polarity voltage (first voltage waveform) during the first time division period, outputs power of negative polarity voltage (second voltage waveform) during the second time division period, and stops outputting power at the end of the second time division period. Therefore, the first operation of the garden lights 30 is that all the garden lights 30 start to light up after sunset. The garden light 30 set in the first section division time division is turned off or the brightness is adjusted to be dark after the first set time point, which is the second operation of the garden light 30, and the garden light 30 set in the second section division time division is turned off after the second time division ends (i.e., after dawn). If it is a three-section division time division function, the three time periods are divided into a total of three time periods, namely, from after sunset to the end of the first set time point, from the end of the first set time point to the end of the second set time point, and from the end of the second set time point to dawn. Moreover, the power sent out from the power supply control box system 10 is sent out in the form of positive, negative, and positive voltages (first, second, and third voltage waveforms) in sequence according to the three time division time periods, and the power is stopped at dawn. For the same reason, if a large number of N-section division time-sharing is required, the selected garden light 30 can be made to perform the Ni-th operation by modulating the voltage polarity exchange, polarity exchange frequency, and polarity exchange duty cycle of the power voltage of the Ni-th voltage waveform from any one of the N-1-th set time points after sunset to the time when the night begins to break and the sun begins to shine, thereby achieving more section division time-sharing function control.

[0015] Among them, the power supply control box system 10 can output power in different time division time periods and in the above-mentioned voltage polarity exchange manner, and in the case of three-section division time division as an example, the power can be output in the order of reverse polarity, negative polarity, negative polarity, and finally power off, or the power can be output in the order of modulating the positive and negative polarity frequencies F1, F2, F3, and finally power off, or the power can be output in the order of modulating the positive and negative polarity duty cycles Duty1, Duty2, Duty3, and finally power off. If the function of controlling the garden light 30 includes not only turning it on and off, but also controlling brightness, light color, and other functions, the control power output from the power supply control box system 10 may adopt a composite method of polarity switching frequency and duty cycle as necessary, for example, the power may be output in the order of F1&Duty1, F2&Duty1, F3&Duty2, and finally the power is turned off, where the switching frequencies F1, F2, and F3 represent the first, second, and third time divisions respectively, and the duty cycles Duty1 and Duty2 represent 100% brightness and 30% brightness respectively, so that the garden lights 30 that are turned on in the first and second time divisions are fully lit, and as for the garden lights 30 that are still lit in the third time division, the brightness of the garden lights 30 that have a dimmer unit built in is changed to 30%, and the light of the garden lights 30 that do not have a dimmer unit is maintained at full brightness.

[0016] The novel contents and features of the present invention will be described in detail below with several embodiments from simple to complex, and the light sensor circuit of the day / night sensing unit and the timer circuit of the internal clock unit are installed in the power supply box system 10, and each garden light 30 selects a required function mode according to the needs of the installation section, and controls the on and off times of the garden lights 30 of different sections according to different voltage attributes output from the power supply box control system 10, and the voltage attributes include methods such as voltage positive and negative polarity exchange, positive and negative polarity exchange frequency modulation and / or positive and negative polarity duty cycle modulation, and other PIR control unit parts that expand and match functions such as motion detection (PIR) are installed in each independent garden light or group control device for use. However, the intrinsic meaning of the present invention patent is not limited to the combination methods of these embodiments, and can be described as follows with reference to the accompanying drawings.

[0017] (Example of garden light divided into two sections and time-sharing function) In an embodiment of the two-section time-division selection function of the garden light, each garden light in the garden light control system of the present invention can be provided to the user to select between two functions: a function of turning on at dusk and turning off at dawn (i.e., turning on at night and turning off during the day, or referred to as the Dusk to Dawn, D / D function), and a function of turning on at dusk and turning off after the time set by the timer circuit has elapsed (Timer function).Therefore, a large number of garden lights in the garden are configured into two types of garden light groups with different functions, and the implementation method of this embodiment will be described below.

[0018] FIG. 1 is a system block diagram of an embodiment of the two-zone division function of the garden light control system of the present invention. As shown in the figure, the preferred embodiment includes a power supply control box system 10, which is used to receive power from a power source 20, and which is also connected to a number of garden lights 30 via a power supply cable 40. Each garden light 30 allows the user to select the above-mentioned D / D function or Timer function according to the needs of its installation area or application, and realizes time-division division to control its lighting.

[0019] Next, FIG. 2 is a functional block diagram of the power supply control box system 10 of the present invention. As shown in the figure, the above-mentioned power supply 20 of its main power loop circuit is connected to the polarity switching circuit 12 through the power supply preparation circuit 11, and transmits power to the output terminal 13, and is connected to the external garden light 30 through the above-mentioned power supply cable 40. The power supply control box system 10 also implements a central control circuit 14 which receives the current, voltage and messages of the light sensor circuit 15 and the timer circuit 16 of the load loop circuit, and comprehensively judges the light control timing through the central control circuit 14. The polarity switching circuit 12 controls the garden light 30 to output the required power, and at the same time, can use polarity switching to match the circuit of the garden light 30 to achieve the function of time-division section division lighting.

[0020] FIG. 3 is a block diagram of the internal circuit of one garden light 30. As shown in the figure, the garden light 30 is mainly composed of a polarity / pulse detection circuit 31, a light circuit 32, and a selection switch 33. The polarity / pulse detection circuit 31 can detect the polarity of the voltage sent from the power supply control box system 10, and can provide two selectable paths, namely, "positive polarity only pass" (the present embodiment is described using positive polarity, and it may be designed to pass only negative polarity) and "polarity unrestricted pass". Among them, the light circuit 32 mainly has a traditional lamp and one or a number of LED lamps. Moreover, the selection switch 33 (Change Over Switch) is used to provide the user with the function mode (D / D function or Timer function) that can be switched in advance after the garden light 30 is connected to the power supply cable 40. Alternatively, as shown in FIG. 4, a connector 34 can be used instead of the selection switch 33.

[0021] FIG. 5 is a table showing the D / D function, the Timer function and the protocol of the power polarity exchange of this embodiment. As shown in the figure, the polarity of the voltage of the power sent out from the power supply control box system 10 is, as shown in FIG. 6, after sunset, the system refers to the messages of the optical sensor circuit 15 and the timer circuit 16, and controls the polarity switching circuit 12 to first output a positive polarity voltage (first voltage waveform) to the power supply loop circuit (power supply cable 40) by the central control circuit 14. At this time, in all the garden lights 30, regardless of whether the selection switch 33 switches the path to either "positive polarity only pass" or "polarity unrestricted pass", all of them obtain power and perform the first operation of lighting. For example, the selection switch 33 of the first garden light 30 switches the path to the first path of "positive polarity only pass", while the selection switch 33 of the second garden light 30 switches the path to the second path of "polarity unrestricted pass", and both of the two garden lights 30 are turned on by this positive polarity first power signal. When the timer circuit 16 of the power supply control box system 10 reaches time t1 (e.g., midnight), it sends out a voltage (second voltage waveform) that has changed to negative polarity. At this time, the selection switch 33 of the first garden light 30 switches the path to the first path of "positive polarity only passing", and since it is not possible to form a current path in the light circuit 32 that fluctuates due to the polarity of the voltage, it is turned off. Meanwhile, the selection switch 33 of the second garden light 30 switches the path to the second path of "polarity not limited passing", so it continues to be turned on without being restricted by the polarity of the power voltage, and the light sensor circuit 15 of the power supply control box system 10 notifies the power supply control box system 10 to stop the output of power all at once until it detects that the night has ended and the sun has begun to shine (t2), and all the garden lights 30 can be turned off.

[0022] Figures 7(a) and 7(b) are diagrams showing two examples of the internal circuit of the garden light 30 of this embodiment (however, the present invention is not limited to such a circuit method). Following the explanation in the previous paragraph and the protocol of this embodiment shown in Figure 5, the selection switch 33 of the garden light 30 switches the path to "positive polarity only passing", that is, selects the control function of the garden light 30 to "Timer". The path is connected from the circuit wiring of the power supply cable 40 to the diode cascaded inside the polarity / pulse detection circuit 31 as shown in Figure 7(a), through the selection switch 33, and then to the light circuit 32. When a positive polarity voltage (first voltage waveform) is output from the central control circuit 14, the diode inside the polarity / pulse detection circuit 31 becomes forward conductive, allowing the light to be turned on. Or, as in the light circuit 32 of FIG. 7(b), in which FIG. 7(b) utilizes the unidirectional conduction and light-emitting characteristics of the LED to match the polarity / pulse detection circuit 31 to the light circuit 32, it is particularly applied to an LED lighting circuit, and the power is turned on through the forward conduction of the left LED. Moreover, when the power supply control box system 10 changes to send out a negative polarity voltage (second voltage waveform), the diode inside the polarity / pulse detection circuit 31 in FIG. 7(a) cannot be displaced in the reverse direction to conduct, so the light is turned off. On the other hand, the light circuit 32 of FIG. 7(b) changes to the extinguishment state because it cannot form the only left LED route in the reverse direction to conduct. Moreover, the selection switch 33 switches the path to "polarity unrestricted passage", that is, even if the "D / D" control function is selected, the garden light 30 is not restricted by the polarity of the voltage of the power supply in the internal path of the polarity / pulse detection circuit 31 in Fig. 7(a), or the light circuit 32 in Fig. 7(b) is turned on when the path is changed to the LED route on the right side and conducts. Therefore, the light can be continuously turned on until dawn, and then it can be turned off by stopping the output of power to the power supply control box system 10.

[0023] The power for the device of the present invention is not limited to a DC power system, but can be applied to an AC power system as well. The waveform of a general AC power supply is as shown in FIG. 8(a). In this embodiment, the power supply control box system 10 first passes through the power supply preparation circuit 11 inside the power supply control box system 10 to perform full-wave rectification, and then according to the above-mentioned principle, sends out a positive voltage at sunset first. After the time t1 set by the timer circuit 16 has elapsed, the power supply control box system 10 then changes to send out a negative voltage (second voltage waveform). As shown in FIG. 8(b), this causes some of the garden lights 30 to be turned off first (i.e., the lights that only pass positive polarity are selected), and the remaining garden lights 30 stop sending out power all at once until the light sensor circuit 15 of the power supply control box system 10 detects that dawn has broken and the sun has begun to shine (t2), and all of them are turned off. The operation procedure is the same as that of the DC power system described above.

[0024] From the above embodiment, the innovative spirit of the garden light control system of the present invention can be obtained, which improves the traditional same set of garden light devices that only allow all garden lights to perform the selected D / D function or Timer function, and the present invention uses a novel method to allow multiple garden lights 30 on the same power supply cable 40 to perform the D / D function for the garden lights 30 in some areas, while the garden lights 30 in some areas can also select and use the Timer function at the same time, thereby meeting the demand for time-division and segmented lighting, and without the need to implement multiple loop circuits.

[0025] Example of multi-partition division function Next, following the principle of the embodiment of the two-partition division function of the D / D function and the Timer function described above, the present invention increases the more diversified time division partition division function by dividing each time division time period into attribute methods such as the number of times of voltage polarity exchange, modulation of exchange frequency of different positive and negative polarities, or duty cycle of different positive and negative polarities, and in the next embodiment of the multi-partition division function, three partition division functions, Timer1, Timer2, and D / D, are described, and one more Timer function option is added compared to the previous embodiment.

[0026] First, this embodiment will be described using the number of times the polarity of the voltage is exchanged as an example. The polarity of the voltage sent from the power supply control box system 10 is exchanged as shown in FIG. 9. FIG. 10 is a block diagram of the system of this embodiment of the multi-section division function. The circuit of the garden light 30 is composed of a polarity / pulse detection circuit 31, a selection switch 33, a switch circuit 35, and a light circuit 32. As shown in FIG. 15, the polarity / pulse detection circuit 31 has an operation truth table in which, when the power supply control box system 10 sends out the polarity of the first positive voltage, the output terminals of t1, t2 and D / D are all set to output an effective signal. When it is detected that the polarity of the first positive voltage output from the power supply control box system 10 is to be changed to a negative voltage (second voltage waveform), the output terminal of t1 is changed to output an ineffective signal, and the remaining t2 and D / D output terminals are still maintained to output an effective signal. After it is detected that the negative voltage (second voltage waveform) output from the power supply control box system 10 is to be changed back to a positive voltage, Then, the output terminal of t2 is also changed to output an inactive signal, and the output terminal of t1 is still maintained to output an inactive signal, and the output terminal of D / D is still maintained to output an active signal, and the switch circuit 35 is used to select the output signal of t1, t2 or D / D of the polarity / pulse detection circuit 31 according to the switching position of the selection switch 33, and controls whether the power output from the power supply control box system 10 passes through the switch circuit 35 according to the received active signal or inactive signal, so as to turn on or off the LED lamp (or traditional light bulb) of the light circuit 32.

[0027] After the above description, first, referring to the protocol of the multi-section division function of exchanging the polarity of the voltage of the power in Fig. 16, when the light sensor circuit 15 of the power supply control box system 10 detects that the sun has set, the power supply control box system 10 first sends out a positive voltage, and at this time, regardless of whether the user switches the selection switch 33 of all the garden lights 30 to any of the function options of t1, t2 or D / D as shown in Fig. 10, the output terminals of t1, t2 and D / D all output effective signals, so that the multiple switch circuits 35 are all operated accordingly, so that the multiple light circuits 32 obtain power and light up. After that, when the time reaches t1, the power supply control box system 10 changes to send out a negative voltage (second voltage waveform) (see Fig. 9), and at this time, the garden lights 30 whose selection switches 33 switch to the function of t1 have their output terminals of t1 change to output ineffective signals, so that the multiple switch circuits 35 are disconnected. Therefore, the garden light 30 that selects the function t1 is turned off when there is no power. Meanwhile, the other garden lights 30 that select the function t2 or D / D maintain their t2 and D / D output terminals to still output an active signal, so that the switch circuit 35 is maintained in a conductive state, thereby causing the multiple garden lights 30 to be continuously lit. After that, when the time reaches t2, the power supply control box system 10 changes to output a positive polarity voltage again, and at this time, the garden lights 30 whose selection switches 33 are switched to the function t2 have their output terminals of the t2 change to output an inactive signal, so that the multiple switch circuits 35 are disconnected. Therefore, the garden lights 30 that select the function t2 are turned off when there is no power. Moreover, the garden light 30 which has selected the D / D function with the selection switch 33 maintains its D / D output terminal still outputting a valid signal, so the switch circuit 35 is controlled to be continuously conductive and continues to be lit. The power supply control box system 10 stops sending power to the power supply cable 40 until it detects that dawn has broken and the sun has begun to shine (t3), at which point all the lights are turned off.

[0028] Example of switching frequency and switching duty cycle In the above embodiment, the time division section division control is performed by exchanging the polarity of the voltage of the power supply in different time periods. For the same reason, the method of exchanging the exchange frequency of different polarities or different duty cycles in different time periods may be changed and adopted to achieve the same function control purpose. As in the above three time division "embodiments of multi-section division function", the first power signal, the second power signal and the third power signal are divided into voltage waveforms of exchange frequencies that output three different polarities, low, medium and high, as shown in Fig. 11(a), and are divided into three different frequencies, for example, 1Hz, 5Hz and 10Hz. Or, as shown in Fig. 11(b), voltage waveforms of duty cycles of three different positive and negative polarities, 50%, 75% and 100%, are output in three time periods. Thus, the polarity / pulse detection circuit 31 of the garden light 30 is adopted as a detection circuit that can distinguish the exchange frequency of the voltage polarity, or a detection circuit that can distinguish the duty cycle of the positive and negative polarities. Regarding the relationship between the detection conditions of the polarity / pulse detection circuit 31 and the three-time division power signal, by referring to the protocol of an embodiment of the multi-section division function of exchanging the polarity frequency of the power voltage in FIG. 17 and the protocol of an embodiment of the multi-section division function of exchanging the polarity duty cycle of the power voltage in FIG. 18, it is possible to determine all three time periods t1, t2, and t3 through the identification results of the polarity / pulse detection circuit 31.

[0029] Following the above explanation, during this frame period from after sunset to time t1, regardless of whether the user switches the selection switches 33 of all the garden lights 30 to either t1, t2 or D / D path, the power supply control box system 10 will convert to output the first power signal and operate all the switch circuits 35, thereby causing the light circuits 32 to obtain power and turn on. When the time reaches t1, the power supply control box system 10 converts to output a second power signal (different polarity switching frequency or different duty cycle), and the selection switches 33 of some of the garden lights 30 switch the path to the path of t1, and at the output end t1, the switching frequency or duty cycle of the second power voltage does not belong to the range of the output valid condition through the detection result of the polarity / pulse detection circuit 31, so it no longer outputs an valid signal, and the multiple switch circuits 35 are disconnected, and the multiple light circuits 32 are turned off when there is no power, while the other garden lights 30 that select the path of t2 or D / D are kept on. Also, when the time reaches t2 continuously, the power supply control box system 10 converts to output a third power signal, and at this time, the selection switch 33 switches the path to the path of t2, and the switch circuit 35 of the garden light 30 does not output an effective signal because the switching frequency or duty cycle of the voltage of the third power does not belong to the range of the output effective condition through the detection result of the polarity / pulse detection circuit 31, so the light circuit 32 is turned off when there is no power, while the garden light 30 that selected the D / D path continues to be turned on, and the power supply control box system 10 stops sending power until it detects that the night has dawned and the sun has begun to shine (t3), and turns off all the garden lights 30. For the same reason, it is possible to control the selection of each garden light 30 and the execution of lighting functions in more time-division divisions by changing the state of the switching of the polarity of the different voltages of the power supply power, the switching frequency of the positive and negative polarities, or the duty cycle of the positive and negative polarities, etc., in more different time periods.

[0030] (Example in which a function control device is provided independently of the garden light) Referring to the schematic diagram of Figure 12, which shows a function control device provided independently outside the garden light, the garden light circuit in the above-mentioned embodiment of the present invention includes a polarity / pulse detection circuit 31, a selection switch 33, a switch circuit 35, and a light circuit 32, of which the polarity / pulse detection circuit 31, the selection switch 33, and the switch circuit 35 may be provided independently as a function control device 50A, and the function control device 50A may be mounted outside the garden light 30 and interposed between the power supply cable 40 output from the power supply control box system 10 and the garden light 30, thereby further simplifying and simplifying the circuit of the garden light 30, which is advantageous for unifying the garden light circuit.

[0031] The independently installed function control device 50A is not limited in shape and structure, and can be independently packaged as a single control box device, or can be packaged in a connector between the output circuit wiring from the power supply control box system 10 and the garden light 30. The independently packaged function control device 50A can also be installed as a group control device 50B, and is used to connect several light groups 30a of a number of garden lights that have the same functional demands and have their partition division points close to each other, as shown in the schematic diagram of the group control system in Figure 13, and these light groups 30a of the garden lights are controlled to perform the same lighting function, and different group control devices can select different lighting function options, such as the above-mentioned partition division time division lighting function of t1, t2 or D / D.

[0032] Example of group control and composite multi-partition division function In addition to the function of the garden light to achieve the multi-section division function by the polarity switching control signal issued from the power supply control box system 10, the group control device 50B can reserve additional function options and additional circuit interfaces, for example, can be used to match other additional function circuits such as a motion detection circuit, and controls the selection of the light group 30a of the garden light under its jurisdiction and the execution of more multi-dimensional lighting functions according to the changes and conditions of the voltage polarity, polarity switching frequency, and polarity switching duty cycle sent from the power supply control box system 10. As shown in the block diagram of the system in this embodiment in FIG. 14, the internal circuit of the group control device 50C includes a polarity / pulse detection circuit 31, a function selection circuit coupled to a selection switch 33, a motion detection circuit 36, a switch and control circuit 37, etc. As in the two previous embodiments, the system may set a time period from sunset to turning on for a certain period of time and then turning off, or may set a time period from sunset to turning on a certain period of time and then turning off as dawn breaks and the sun begins to shine, or may set any time period during the night. The functions of these time-sharing time periods are described in detail in the previous two embodiments, and in this embodiment, the control method for other expansion functions is described as follows, taking the motion sensing function as an example.

[0033] Referring to the system protocol of the embodiment of the composite multi-zone division function in FIG. 19, the power supply control box system 10 outputs the power signal in each time division period by modulating the voltage polarity exchange frequency and duty cycle, and the polarity / pulse detection circuit 31 of the group control device 50C outputs an effective signal according to the detection conditions of each output end when the conditions are met; In accordance with the selection switch 33, the switch and control circuit 37 controls to achieve the purpose of the function selected by the light circuit 32. Suppose that the "motion detection function" is selected as a function option of the group control device 50C, and the power supply control box system 10 outputs a first power signal in the first time division period after sunset with a switching frequency of its voltage waveform F=1Hz, duty cycle=50%, which does not match the detection condition for the effective signal at the pir output terminal of the polarity / pulse detection circuit 31. Therefore, since no effective signal is output from the pir output terminal, the motion detection circuit 36 ​​does not operate, and the switch and control circuit 37 is in a non-conductive state, the light group 30a of the garden light at the rear end does not light up accordingly. Therefore, in the second time division period, the power supply control box system 10 outputs a second power signal with a switching frequency of its voltage waveform F=5Hz, duty cycle=50%, which does not match the detection condition for the effective signal at the pir output terminal of the polarity / pulse detection circuit 31. Since cycle=100% matches the detection condition of the effective signal of the pir output terminal of the polarity / pulse detection circuit 31, the pir output terminal outputs an effective signal to activate the motion detection circuit 36, and after the motion detection circuit 36 ​​detects that a person or a car is approaching, the PIR output terminal is used to turn on the switch and control circuit 37, and the garden light 30 in the group is turned on, so as to achieve the purpose of effective lighting for people and cars. After a certain time has passed since the person or car left, the motion detection circuit 36 ​​changes to output an ineffective signal from its PIR output terminal according to the characteristics, and the switch and control circuit 37 controls the loop circuit to turn off, turning off the garden light 30 in the group, and thus repeats in an infinite cycle, and the power supply control box system 10 stops outputting power and turns off the light naturally until it detects that the night has dawned and the sun has begun to shine. For the same reason, based on the changeable detection conditions of the polarity / pulse detection circuit 31, like other system protocols of the embodiment of the composite multi-section division function of Figure 20, the power supply control box system 10 turns on the motion detection function when it outputs the first power signal in the first time division period after sunset, while in the second time division period, the power supply control box system 10 turns off the motion detection function when it outputs the second power signal.In addition, the composite multi-section division function of the present invention is not limited to use in group garden lights, and when the internal circuit of the group control device 50C of this embodiment is integrated into an independent garden light 30, the lighting function of the independent garden light 30 has a multi-function option, namely, combining motion detection. According to this control method, the time-sharing time period can be expanded as required, and it can even be extended to provide functions such as color temperature and brightness of the garden light 30, so as to achieve more lighting needs of time-sharing section division and composite multi-function.
