Description

Control system and control method of garden lamp

The present invention relates to a control system for garden lights and a control method thereof, in particular to a system composed of a power supply control box system, a plurality of garden lights and the power supply lines between them, especially to provide garden lights or groups of garden lights The multi-function control enables the garden light to automatically execute the lighting mode that the user has selected to meet the needs of time-sharing and zoned lighting in the garden.

The customary garden lights or outdoor lights lighting system are used to install at various locations in the garden to provide the necessary lighting after nightfall. For example, as shown in US Patent Publication US7632159B2, it is mainly composed of a control box, many garden lights, and a power supply line. They are respectively connected to the power supply line, and the power supply line is also connected to the control box. Thereby, the control box outputs voltage to each garden lamp through the power supply line, so that the control box can uniformly control power supply or power-off, so that most garden lamps can be turned on and off at the same time.

The basic control function of the conventional control box has a light sensor circuit to achieve the Dusk to Dawn (D/D) power supply control function (D/D function for short), so it is used as the light sensor circuit of the control box When night is detected, it will output a uniform voltage to the garden lights through the power supply line, and light up the garden lights in the garden at the same time to achieve the lighting purpose; and when the light sensor circuit detects the dawn and dawn Cut off the power supply, and then turn off all garden lights. In addition, the control box with advanced functions is equipped with a set of timer circuits (Timer), which allows users to set the time to turn off the lights. For example, the lights can be set to turn off after 6 hours, so the light sensor circuit can detect the signal at night. The control box uniformly controls all garden lights to turn on at the same time. After 6 hours, it will automatically cut off the power supply and turn off the lights of all garden lights, or set the time to turn on and turn off the lights according to the timer circuit. .

However, the above-mentioned garden lights under the same control box cannot choose different turn-off time or other lighting functions at the same time; in detail, the above-mentioned conventional garden light lighting system is detected by the light sensor circuit of the control box or timer The automatic control technology of the circuit, under the same power supply line, can only control the garden lights to turn on or turn off the lights uniformly, and cannot allow the user to set certain groups of lights to be lit until dawn after night, while some groups of lights are Turn off the lights in advance after a period of time. In order to achieve the above-mentioned functions, theoretically, a control device can be installed inside or outside each garden light (for example, as shown in US Patent Publication No. US20090195063A1), but this will cause each garden light to be expensive. It is complicated, and it is impossible to use the control box to simply control the lighting time of each segment. Or you can use a control box to connect two power supply lines, one of which is the power supply loop controlled by the above-mentioned light sensor circuit, and the other power supply line is the power supply loop controlled by the above-mentioned timer circuit, so that most garden lights Connected to each power supply line separately, although some lamp groups can be lit until dawn after nightfall, some lamp groups will turn off the lights in advance after a period of time; but in this way, two power supply lines must be buried in the garden when wiring. , If you want to turn off some garden lights at multiple times before dawn (for example, 9 pm, midnight, 3 am), it is equivalent to arranging 4 power supply lines, which is not economical for users and increases Installation cost, and construction is troublesome.

For this reason, how to provide users to connect multiple garden lights on the same power supply line based on a power supply control box system and a power supply line, without adding other power supply lines (power supply loops) or implementing high voltage in the garden lights? Cost-effective automatic control device, but only through the selection switch inside or outside each garden light or the selection of different pins according to the electrical connector plugging, it can realize certain light groups (such as aisle lights) into the night The lights are turned on after dawn until dawn, and certain light groups (such as lights for landscaping) can be turned off at the time set by the control box, thereby realizing low-cost time-sharing and multiple lighting functions. Breakthrough innovative technology.

As mentioned in the previous technology, the conventional garden lamp and outdoor lamp system uses a control box to uniformly control the lighting and turn-off time of each garden lamp in the whole area, so as to achieve the purpose of uniformly controlling the lighting. However, as modern people live The trend of space usage is diversified, and different outdoor spaces have different lighting needs. For example, key safety protection spaces need to be illuminated until late or all night; some spaces can be turned off or turned off before midnight to achieve energy-saving effects ; Lanes or footpaths can be lit when people or vehicles approach, turn off the lights or turn off the lights after people or vehicles leave; some areas are required to achieve the landscape or create an atmosphere, and change automatically as time, temperature or season changes Provide lights with different color temperatures and brightness. All these needs are beyond the ability of the above-mentioned conventional garden lights and outdoor light control systems.

The control system and control method of the garden lamp of the present invention provide a simple, novel and unique solution, which can control each power supply by changing the polarity of power supply, modulating the frequency of positive and negative polarity, or modulating the duty cycle of positive and negative polarity. Various lighting functions are selected for garden lights to meet the lighting needs of different partitions with different functions and different light-off periods.

The garden light control system of the present invention includes a power supply control box system, optional group control devices, garden lights and their interconnections. The power supply control box system mainly provides function setting, control, and provides the device garden lights, group Group control device needs power, garden lights can be set as independent garden lights or group garden lights, group garden lights are installed in the group under the control of the group control device, and the group garden lights are uniformly controlled by the group control device Lighting time, brightness, etc., independent garden lights are directly installed under the power supply control box system connection like a group control device, receive power and control of the power supply control box system, and determine the lighting time, brightness, and color temperature with reference to its own function settings , Function, etc., through the device and control method of the present invention, it can provide multiple function control of each garden lamp or garden lamp group to meet the lighting needs of zoning and multiple purposes. In addition, the positive and negative polarity conversion control of the device of the present invention can also be used. Reduce the line corrosion problem caused by the electrolysis effect of the fixed polarity for a long time in the DC power supply.

The structural features and other functions and purposes of the present invention are described in detail according to the embodiments of the drawings as follows:

Refer to Figure 1, which is a structural diagram of the garden light control system of the present invention, which includes a power supply control box system 10 and a power supply 20, a power supply line 40 connected to the power supply control box system 10, and a power supply line 40 connected to the power supply line The plurality of garden lights 30 on the 40, wherein: the power supply control box system 10 is used to provide the power required by the garden lights, and receive the day and night signals from the light sensor circuit of the day and night detection unit, and one or more internal The timer circuit of the timing unit turns off the power output during the day, and outputs power with different voltage attributes at different times during the night, including changing the positive and negative polarity of the supply voltage, modulating the positive and negative polarity conversion frequency, or modulating the positive and negative polarity duty cycle, etc. Attribute, used to provide the power required by the garden lamp 30 connected via the power supply line 40, so that the garden lamp 30 can recognize its voltage positive and negative polarity, positive and negative polarity conversion frequency, positive and negative polarity duty cycle and other states, and according to its state or state change situation , Compare the setting switch selection of the garden light function, execute the pre-agreed action (lighting function), and achieve the functions of time-sharing and zoned lighting.

The above-mentioned power supply control box system 10 changes the attribute content of the power voltage provided and the number of changes, which are based on the complexity of the system function and the communication protocol. Take the simple two-zone time-sharing function as an example, the first time-sharing period To start counting time after nightfall, until it reaches a first set time point set by the timer circuit of the internal timing unit; the second time-sharing period starts after the end of the first time-sharing time and continues until dawn; the power supply The control box system 10 outputs power of a positive polarity voltage (a first voltage waveform) during the first time sharing period, and outputs power of a negative polarity voltage (a second voltage waveform) during the second time sharing period, and in the second time sharing period Turn off the output power at the end of the time; therefore, all garden lights 30 start to light up after nightfall, this is the first action of the garden lights 30; the garden lights 30 set to the first partition time-sharing are at the first set time point Turning off the lights afterwards or dimming the brightness is the second action of the garden lights 30. The garden lights 30 set to the second divisional time-sharing will be turned off after the second time-sharing (ie after dawn). If it is a three-zone time-sharing function, the three time periods are from the end of night to the end of the first set time point, the end of the first set time point to the end of the second set time point, and the end of the second set time point to dawn. There are three time periods in total; and the power sent by the power supply control box system 10 will sequentially send out positive, negative, and positive voltages (first, second, and third voltage waveforms) according to the above three time-sharing time periods, and then Turn off the electricity at dawn. In the same way, if more time-sharing of N divisions is needed, use any N-1th set time point after nightfall until dawn, and cooperate with the voltage polarity conversion, polarity conversion frequency, and polarity conversion of the power of the Nith voltage waveform. The periodic modulation makes the selected garden lamp 30 perform the Nith action, achieving more divisional time-sharing function control.

Among them, the power supply control box system 10 outputs power in different time-sharing periods and uses the above-mentioned voltage polarity conversion method. Taking three-zone time-sharing as an example, the polarity can also be reversed: negative polarity, positive polarity, negative polarity, and finally Output power in the sequence of turning off the power, or output power in the sequence of modulating the positive and negative polarity of the frequency F1, F2, F3, and finally turning off the power, or in the sequence of modulating the positive and negative polarity duty cycles Duty1, Duty2, Duty3, and finally turning off the power Output power; if the garden light control functions include brightness, light color, or other functions, in addition to turning on and off the lights, the control power output by the power supply control box system 10 can be changed according to the need. Duty cycle compound mode, for example: F1&Duty1, F2&Duty1, F3&Duty2, the last power-off sequence output power, where the conversion frequency F1, F2, F3 represent the first, second, and third time sharing, and the duty cycle Duty1, Duty2, respectively Represents 100% brightness and 30% brightness. The garden light 30 that lights up at the first and second time is all on, and the garden light 30 that lights up at the third time has a built-in dimming. For the unit, the light is turned to 30% brightness, and if the dimming unit is not set, the light is still fully bright.

In order to explain in detail the innovative content and features of the present invention, several embodiments are listed below from simple to complex, and the light sensing circuit of the day and night detection unit and the timer circuit of an internal timing unit are set in a power supply control box. In the system 10, each garden lamp 30 selects the required function mode according to the requirements of the installation partition, and controls the different voltage attributes of the output of the system 10 according to the power supply box, including changing the polarity of the transmission, adjusting the frequency of the positive and negative polarity, and or adjusting Changing the positive and negative polarity of the work cycle, etc., control the time of lighting and turning off the garden lights 30 in different zones. Other PIR control units that expand and integrate functions such as motion detection (PIR) are installed in each independent garden light or group Control device use. However, the connotation of the patent of the present invention is not limited to the combination of these embodiments. I would like to further explain the following with the accompanying drawings:

[ Examples of time-sharing functions of garden lights in two partitions ]

The embodiment of the two-zone time-sharing selection function of the garden light is an example of each garden light in the garden light control system of the present invention. Dusk to Dawn, D/D function), or turn on the light at night and turn off the light after the time set by the timer circuit (Timer function), making most garden lights in the garden form a garden with two different functions Lamp group, the following describes the implementation of this embodiment:

As shown in FIG. 1, it is a system block diagram of a two-part functional embodiment of the garden light control system of the present invention. The preferred embodiment includes a power supply control box system 10 for receiving a power supply 20 The power supply control box system 10 is connected to a plurality of garden lights 30 via a power supply line 40. Each garden light 30 allows the user to select the above-mentioned D/D function or Timer function according to its installation area or purpose. Realize time-sharing and zone control of its lighting.

As shown in FIG. 2 again, it is a functional block diagram of the power supply control box system 10 of the present invention. The above-mentioned power supply 20 of the main power loop passes through a power supply preparation circuit 11, and then is connected to a polarity switching circuit 12 to be transmitted to the power output terminal. 13, to connect to the external garden light 30 via the power supply line 40; the power supply control box system 10 implements a central control circuit 14 to receive load loop current, voltage, and a light sensing circuit 15 and a timer circuit 16 Information, the central control circuit 14 comprehensively judges the lighting control timing, and then controls the polarity switching circuit 12 to output the power required by the garden light 30 while using polarity conversion to match the circuit of the garden light 30 to achieve the divisional lighting Features.

As shown in FIG. 3, it is a block diagram of the internal circuit of a garden lamp 30. The garden lamp 30 is mainly composed of a polarity/pulse wave detection circuit 31, a lamp circuit 32 and a selection switch 33. The polarity/pulse detection circuit 31 can detect the polarity of the voltage sent by the power supply control box system 10, and provide "positive polarity pass only" (in this embodiment, the positive polarity is described, and it can also be designed to only pass the negative polarity) and There are two alternative paths for "pass through without restriction"; the light circuit 32 mainly has traditional lamps and one or more LED lights; and the changeover switch 33 (Change Over Switch) is used to provide the user with the garden light After 30 is connected to the power supply line 40, its function mode (D/D function or Timer function) can be switched in advance; or as shown in FIG. 4, the selector switch 33 can also be replaced by a connector 34.

Refer to Fig. 5, which is the agreement of the D/D function, Timer function and power polarity conversion in this embodiment. The power voltage polarity sent by the power supply control box system 10 is shown in Fig. 6; when it is night, the system refers to the light The information of the sensing circuit 15 and the timer circuit 16 causes the central control circuit 14 to control the polarity switching circuit 12 to output the positive polarity voltage (the first voltage waveform) to the power supply circuit (power supply line 40). At this time, all garden lights 30. Regardless of whether the selector switch 33 is switched to the "pass through with positive polarity" or "pass through with no polarity", it will receive power to perform the first action of lighting; for example, the selector switch 33 of a first garden light 30 is switched on The first path of "pass through with positive polarity", the selector switch 33 of the other second garden light 30 is switched to the second path with "pass through without polarity". This positive first power signal can make two garden lights 30 lights up. When the timer circuit 16 of the above-mentioned power supply control box system 10 reaches t1 (for example, midnight 0:00), it switches to sending out a negative voltage (second voltage waveform); at this time, the selector switch 33 of the first garden light 30 is switched to In the first path of "pass through with positive polarity", the lamp circuit 32 cannot form a current path and turns off the light due to the change in voltage polarity; and the selector switch 33 of the second garden light 30 is switched to the second path of "pass through without polarity". The channel is not limited by the polarity of the power and voltage, and it can continue to light up until the light sensor circuit 15 of the power supply control box system 10 detects dawn and daybreak t2, and informs the power supply control box system 10 to stop transmitting power uniformly, that is, it can be turned off All garden lights 30.

Figures 7(a) and 7(b) are two examples of the internal circuit of the garden lamp 30 of this embodiment (but the present invention is not limited to this type of circuit), following the description of the previous paragraph and the agreement of this embodiment in Figure 5, the garden lamp The selector switch 33 of 30 is switched to the "pass through with positive polarity" path, that is, the light is selected as the "Timer" control function. This path is from the power supply line 40, as shown in Figure 7(a) through the polarity/pulse detection circuit 31 A series of diodes, selector switch 33, and then connected to the lamp circuit 32, when the central control circuit 14 outputs a positive polarity voltage (first voltage waveform), the polarity/pulse detection circuit 31 internal diodes can be forwarded Turn on, allowing the light to be lit; or the light circuit 32 shown in Figure 7(b), where Figure 7(b) uses the unidirectional conduction and light-emitting characteristics of the LED to integrate the polarity/pulse detection circuit 31 into the light circuit 32, which is especially suitable for The LED lamp circuit, the electric power passes through the left side LED to turn on the light. When the above-mentioned power supply control box system 10 is switched to send out a negative polarity voltage (the second voltage waveform), the diode inside the polarity/pulse wave detection circuit 31 in Figure 7(a) becomes reversely unable to conduct, and forms a switch. The light; and the light circuit 32 of Figure 7 (b), the only left LED routing also formed a reverse direction and can not be turned on, and turned off the light. When the selector switch 33 is switched to the "pass through without limit" path, that is, the lamp is selected as the "D/D" control function. Figure 7(a) The internal path of the polarity/pulse detection circuit 31 is not affected by the power supply voltage. Polarity restriction, or the light circuit 32 of FIG. 7(b) can be switched on through the right LED route to turn on the light, so the light can continue to be lit until dawn, and then the light is turned off because the power supply control box system 10 stops delivering power.

The power used by the device of the present invention is not limited to DC power systems, but is also applicable to AC power systems. The general AC power supply waveform is shown in Figure 8(a). This embodiment can first pass through the internal power supply preparation circuit of the power supply control box system 10 11 After full-wave rectification, according to the aforementioned principle, the positive polarity voltage is first sent out when it is dark. After the time t1 set by the timer circuit 16, the power supply control box system 10 is then converted to send out the negative polarity voltage (the second voltage waveform ), as shown in Figure 8(b), so that a part of the garden lights 30 are turned off first (that is, the lights that are restricted to the positive polarity are selected); After the circuit 15 detects the dawn t2, it stops sending power uniformly, that is, all lights are turned off, and the action procedure is the same as the aforementioned direct current system.

It can be seen from the above embodiments that the innovative spirit of the garden light control system of the present invention is improved. The same garden light device can only select all garden lights to perform the D/D function or Timer function. Many garden lights 30 on the wire 40 can allow garden lights in certain areas to perform D/D functions, and garden lights in certain areas can also use the Timer function to meet the needs of time-sharing and zone lighting without the need to implement Into multiple loops.

[ Multi-partition function embodiment ]

Continuing the principle of the two-partition functional embodiment of the D/D function and the Timer function described above, the present invention can use the power supply control box system 10 voltage polarity change times, different modulation positive and negative polarity conversion frequencies, or different modulation positive and negative polarities. The working period and other attribute methods are used to separate the time-sharing periods to add more diversified time-sharing partition functions. The following multi-partition function examples illustrate the three partition functions of Timer1, Timer2, and D/D, which are implemented compared to the previous one. Example to add a Timer function option.

First, take the number of voltage polarity conversions as an example to illustrate this embodiment. The voltage polarity conversion sent from the power supply control box system 10 is shown in FIG. 9, and FIG. The circuit of the lamp 30 is composed of a polarity/pulse wave detection circuit 31, a selector switch 33, a switch circuit 35 and a lamp circuit 32; the action truth table of the polarity/pulse wave detection circuit 31 is shown in Fig. 15, when the power supply When the control box system 10 sends out the first positive voltage polarity, the t1, t2 and D/D output terminals are all set to output enable signals. When it is detected that the first positive voltage polarity output by the power supply control box system 10 is changed to When the voltage of negative polarity (the second voltage waveform), its t1 output terminal is converted to output a non-enable signal, and the other t2 and D/D output terminals still keep outputting the enable signal. When the negative pole output of the power supply control box system 10 is detected After the positive voltage (the second voltage waveform) is converted to positive voltage again, its t2 output terminal is also converted to output a non-enable signal, and the t1 output terminal still maintains the output of the non-enable signal, while the D/D output terminal still maintains Output an enabling signal; the switch circuit 35 is used to select the t1, t2 or D/D output signal of the polarity/pulse detection circuit 31 according to the switch position of the selector switch 33, and the received enable signal or non-inducing The power signal is used to control whether the power output by the power supply control box system 10 passes through the switch circuit 35, so that the LED light (or traditional light bulb) of the light circuit 32 is turned on or off.

After following the above description, firstly refer to Figure 16 for the multi-zone function protocol for changing the polarity of the power voltage. When the power supply control box system 10 detects the nightfall through the aforementioned light sensing circuit 15, the power supply control box system 10 first sends out a positive voltage. At this time, no matter if the user switches the selection switches 33 of all garden lights 30 to t1, t2 or D/D function options shown in Figure 10, because at this time t1, t2 and D/D output terminals are all output enable signals, Therefore, the switch circuits 35 will be activated, so that the lamp circuits 32 will receive power to turn on the lights. After that, the power supply control box system 10 switches to sending out a negative polarity voltage (second voltage waveform) when the time reaches t1 (as shown in FIG. 9). At this time, the selector switch 33 of the garden light 30 is switched to the function t1, Since the t1 output terminal is converted to output a non-enable signal, the switching circuits 35 are disconnected, so that the garden light 30 that selects t1 has no power and turns off; and other garden lights with D/D function are selected at t2 30, because its t2 and D/D output terminals still keep outputting the enable signal, the switch circuit 35 is kept on, so that the garden lights 30 keep on. After that, when the time reaches t2, the power supply control box system 10 is switched to send out a positive polarity voltage. At this time, the selector switch 33 of the garden light 30 is switched to the function of t2, and the output terminal of t2 will be converted to non-inductive output. The enable signal turns off the switch circuits 35, so that the garden lamp 30 that selects the t2 function is turned off without power. And the selector switch 33 selects the garden lamp 30 with D/D function, because its D/D output terminal still maintains the output enable signal, the switch circuit 35 is controlled to continue to be turned on, and the light continues to be lit until the power supply control box system 10 detects When it is measured at dawn t3, the power supply to the power supply line 40 is stopped, and all the lights are turned off.

[ Example of changing frequency and changing duty cycle ]

The above-mentioned embodiments illustrate that time-sharing divisional control is performed by changing the voltage polarity of the power supply at different time periods. Similarly, it can also be changed to change different polarity conversion frequencies or different duty cycles at different time periods to achieve the same function. For the control purpose, as in the aforementioned three time-sharing "multi-zone function embodiment", the first power signal, the second power signal, and the third power signal are changed to output low, medium, and high as shown in Figure 11(a). Voltage waveforms with different polarity conversion frequencies, such as 1Hz, 5Hz, 10H, three different frequencies; or as shown in Figure 11(b), output 50%, 75%, and 100% of the three different positive and negative polarity work cycles in the three time periods. Voltage waveform. The polarity/pulse wave detection circuit 31 of the garden lamp 30 is also changed to a detection circuit that can identify the frequency of voltage polarity conversion, or a detection circuit that can identify positive and negative working cycles, and its polarity/pulse detection circuit detection conditions and three The time-sharing power signal relationship is shown in the agreement of the multi-zone function embodiment of transforming the power voltage polarity frequency in FIG. 17, and the agreement of the multi-zone function embodiment of transforming the power voltage polarity duty cycle in FIG. From the recognition result of the detection circuit 31, the three time periods t1, t2, and t3 can be determined.

Following the above description, during the period from night to time t1, regardless of whether the user switches its selector switch 33 to t1, t2 or D/D path, the power supply control box system 10 is converted to output the first power The signal will cause the switch circuit 35 to operate, so that the lamp circuit 32 receives power and lights up. When the time reaches t1, the power supply control box system 10 converts to output a second power signal (different polarity conversion frequency or different duty cycle), and part of the garden lamp 30's selector switch 33 is switched to the t1 path, the output The terminal t1 is not in the range of the output enable condition due to the voltage conversion frequency or duty cycle of the second power, and the result of the detection by the polarity/pulse detection circuit 31 is not within the range of the output enable condition, and the enable signal is no longer output. The light circuits 32 turn off the lights without power, and the other garden lights 30 that select the t2 or D/D path keep turning on. When the time continues to reach t2, the power supply control box system 10 is converted to output a third power signal. At this time, the selector switch 33 is switched to the garden lamp 30 at t2, and the switch circuit 35 changes the frequency or duty cycle due to the voltage of the third power. , The detection result of the polarity/pulse wave detection circuit 31 is not within the range of its output enabling conditions, and no more enabling signals are output, so that the lamp circuit 32 has no power and turns off the light, and the garden light 30 with the D/D path is selected, Then the lights will continue to be turned on until the power supply control box system 10 detects that at dawn t3, it stops sending power and turns off all garden lights. In the same way, by changing the state changes such as different voltage polarity, positive and negative polarity conversion frequency or positive and negative polarity duty cycle of the power supply in more different periods, it can be used to control the selection of each garden lamp 30 and perform more time-sharing district lighting. Features.

[ The function control device is independent of the outside embodiment of the garden lamp ]

12, the function selection and polarity recognition unit is independent of the external schematic diagram of the garden lamp. The garden lamp circuit in the foregoing embodiment of the present invention includes a polarity/pulse wave detection circuit 31, a selection switch 33, a switch circuit 35, and a lamp circuit 32. Separate the polarity/pulse detection circuit 31, the selector switch 33, and the switch circuit 35 into a function control device 50A, install the function control device 50A outside the garden lamp 30, and interface with the power supply control box system 10 Between the output power supply line 40 and the garden lamp 30, the circuit of the garden lamp 30 can be made simpler, which is conducive to unifying the garden lamp circuit.

The above-mentioned independent function control device 50A is not limited in shape and structure, and can be independently packaged into a control box device, or can be packaged in a connector between the output circuit of 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, as shown in the schematic diagram of the group control system in Figure 13, which is used to connect and control multiple garden light groups 30a with similar locations and the same functional requirements. These garden light groups 30a perform the same lighting function, and different group control devices can select different lighting function options, such as the above-mentioned t1, t2 or D/D partition time-sharing lighting function.

[ Group control and compound multi-partition function embodiment ]

In addition to the above-mentioned power supply control box system 10 that activates the polarity conversion control signal to achieve the multi-zone function garden light function, the group control device 50B can retain additional function options and circuit interfaces to integrate such as: motion detection circuit and others The additional function circuit, in conjunction with the voltage polarity, the polarity conversion frequency, and the change and status of the polarity conversion duty cycle sent by the power supply control box system 10, controls the garden lamp group 30a under its jurisdiction, selects and executes more diversified lighting functions, this implementation An example system block is shown in FIG. 14. The internal circuit of a group control device 50C includes a polarity/pulse wave detection circuit 31, a function selection circuit combined with a selection switch 33, a motion detection circuit 36, a switch and control circuit 37, and so on. As in the previous two embodiments, the system can be set to the period from which the lights start at night to turn off the lights for a period of time, or it can be set to turn off the lights after a period of time at night, and turn off the lights until dawn, or set to any time at night. The time-sharing period function has been described in detail in the previous two embodiments. In this embodiment, for other amplification functions, taking the motion detection function as an example, the control method is described as follows:

Please refer to the system protocol of the compound multi-zone function embodiment in FIG. 19, where the power signal output by the power supply control box system 10 in each time sharing period is a hybrid modulated voltage polarity conversion frequency and duty cycle, and the group control device 50C The polarity/pulse detection circuit 31 will output an enable signal when the conditions are met according to the detection conditions of each output terminal, and cooperate with the selector switch 33 to enable the switch and control circuit 37 to control the lamp circuit to achieve the selected function; suppose this group The function option of the control device 50C is to select the "motion detection function". When the power supply control box system 10 outputs the first power signal in the first time-sharing period after nightfall, the voltage waveform conversion frequency F=1Hz, Duty cycle=50%, it does not meet the condition of the enabling signal detected at the pir output terminal of the polarity/pulse detection circuit 31, so there is no enabling signal output at the pir output terminal, so that the motion detection circuit 36 does not operate, the switch and the control circuit 37 Therefore, it is in a non-conducting state, and the rear garden lamp group 30a does not turn on.
