Description
Technical Field
The invention relates to the technology of the field of lamp control, in particular to a garden lamp control system and a control method thereof, which are a system formed by a power supply control box system, at least one garden lamp and a power supply line therebetween, so as to provide control of multiple functions of each garden lamp or garden lamp group, and enable the garden lamp to automatically execute a lighting mode selected by a user so as to meet the requirement of time-sharing partition lighting of a garden.
Background
Garden lights (Garden lights) or Outdoor lights (Outdoor lights) lighting systems have been used to provide the necessary lighting after night entry for installation in various locations in a Garden. For example, as shown in US7632159B2, it mainly comprises a Control box (Control box), a plurality of garden lamps, and a power supply line (Cable), wherein the garden lamps are respectively disposed at various positions in the garden, and then each garden lamp is respectively connected to the power supply line, and the power supply line is connected to the Control box. Therefore, the control box outputs voltage to each garden lamp through the power supply line, so that the control box can uniformly control the power supply or power off mode, and a plurality of garden lamps can be turned on and off together.
The basic control function of the control box is used, and the control box is provided with a light sensing circuit to achieve the (D/D) power supply control function (D/D function for short) from sky to Dawn, so when the light sensing circuit of the control box detects that the night comes, a voltage is uniformly output to all garden lamps through the power supply line to light all garden lamps in a garden at the same time, thereby achieving the lighting purpose; when the light sensing circuit detects dawn, the power supply is cut off, and then all garden lamps are turned off uniformly. The control box with the advanced function is provided with a group of Timer circuits (Timer) for providing the user with the setting of the unified turning-off time, for example, the light turning-off after 6 hours can be set, so that the light sensing circuit can be used for detecting signals when the user goes to night, the control box can uniformly control all garden lights to be turned on simultaneously, and the power supply is uniformly and automatically cut off after 6 hours, so that the lights of all garden lights are turned off, or the lights are uniformly set to be turned on and the lights are set to be turned off according to the Timer circuits.
However, the garden lamps under the same control box cannot respectively select different lighting time or other lighting functions at the same time; in detail, the above-mentioned used garden lamp lighting system only can control the garden lamps to uniformly light or turn off under the power supply of the same power supply line by the automatic control technology of the light sensing circuit detection or timer circuit of the control box, so that the user cannot set certain lamp groups to light up to dawn all night by himself, and certain lamp groups turn off in advance after a period of time. If it is desired to achieve the above-mentioned functions, it is theoretically possible to install a control device inside or outside each garden lamp (for example, as shown in U.S. patent publication No. 20090195063 A1), but this would result in expensive price per garden lamp, complicated setting, and simple control of lighting time in each section by using a control box. Or one control box can be connected with two power supply lines, wherein one power supply line is a power supply loop controlled by the light sensing circuit, and the other power supply line is a power supply loop controlled by the timer circuit, so that a plurality of garden lamps are respectively connected with each power supply line, certain lamp groups can be always lighted to dawn after entering the night, and certain lamp groups are turned off in advance after a period of time; however, two power supply lines are buried in the garden during wiring, if garden lamps are turned off in sections at a plurality of time points (such as 9 pm, 0 midnight and 3 am) before dawn, the arrangement of 4 power supply lines is equivalent, so that the power supply lines are not economical to users, the installation cost is increased, and the construction is troublesome.
Therefore, on the basis of a power supply control box system and a power supply line, a user is provided to connect a plurality of garden lamps in the same power supply line, and no other power supply lines (power supply loops) are needed, and no high-cost automatic control devices are needed to be implemented on the garden lamps, but the innovative technology of the invention can be realized by switching the switch in each garden lamp or the switch outside the garden lamp or selecting different pins according to the electric connector, so that certain lamp groups (such as pavement lamps) can be lighted to dawn and on after entering night, and certain lamp groups (such as landscaping lamps) can be turned off at the time point set by the control box, thereby realizing low-cost time-sharing partition and multi-element lighting functions.
As described in the prior art, the known garden lamps and outdoor lamp systems control the lighting and turning-off time of each garden lamp by a control box with the consistency of the whole area, so as to achieve the purpose of uniformly controlling the lighting, but with the diversification trend of the living space of modern people, different lighting requirements are provided for different outdoor spaces, such as the requirement of providing lighting to late night or providing lighting for whole night in important safety protection space; part of the space can be turned off before midnight or the light is turned off, so that the energy-saving effect is achieved; the lane or the small path of the pedestrian can be lighted when people and vehicles approach, and the lights are turned off or turned off after the people or the vehicles leave; the partial areas are required to achieve the landscape or atmosphere creation, and the lighting with different color temperatures and brightness is required to be automatically changed along with the time, temperature or season changes, so that the requirements are not satisfied by the used garden lamp and outdoor lamp control system.

Detailed Description
The invention will now be further illustrated with reference to the drawings and specific examples, which are not intended to limit the invention.
Referring to fig. 1, a garden lamp control system architecture diagram according to the present invention comprises a power supply control box system 10 and a power source 20, a power supply line 40 connected to the power supply control box system 10, and one or more garden lamps 30 connected to the power supply line 40, wherein: the power supply control box system 10 is used for providing power required by a garden lamp, receiving day and night signals sent by a light sensing circuit of a day and night detection unit and time information of a timer circuit of one or more internal timing units, turning off power supply output during the day, and outputting power with different voltage attributes according to different time periods during the night, wherein the power includes the properties of changing the positive and negative polarities of the power supply voltage, modulating the positive and negative polarity conversion frequency or modulating the positive and negative polarity duty cycle and the like, and is used for providing power required by the garden lamp 30 connected through the power supply line 40, so that the garden lamp 30 can identify the states of the positive and negative polarities of the voltage, the positive and negative polarity conversion frequency, the positive and negative polarity duty cycle and the like, and execute pre-agreed actions (lighting functions) according to the state or state conversion conditions compared with the garden lamp function setting switch, thereby achieving the functions of time-sharing and partition lighting.
The power supply control box system 10 converts the attribute content and the conversion times of the power voltage provided by the power supply control box system, and takes a simple two-division time-sharing function as an example, wherein the first time-sharing time period is calculated after entering night, and reaches a first set time point set by a timer circuit of the internal timing unit; the second time-sharing period is started after the first time-sharing period is ended until dawn; the power supply control box system 10 outputs the power of the positive voltage (a first voltage waveform) during the first time-sharing period, outputs the power of the negative voltage (a second voltage waveform) during the second time-sharing period, and turns off the output power at the end of the second time-sharing period; thus, all garden lights 30 begin to illuminate after entering the night, which is the first action of the garden lights 30; the garden light 30 set to the first division is turned off or dimmed after the first set point in time, which is the second action of the garden light 30, and the garden light 30 set to the second division is turned off after the second division is finished (i.e., after dawn). If the time-sharing function is three partitions, the three time periods are three time periods respectively, namely, ending from the night to the first set time point, ending from the first set time point to the second set time point and ending from the second set time point to dawn; the power supply control box system 10 sequentially sends positive polarity, negative polarity and positive polarity voltages (first, second and third voltage waveforms) according to the three time-sharing time periods, and turns off the power at dawn. Similarly, if more N partitions are needed, any N-1 time point is set after entering night until dawn, and the selected garden lamp 30 executes the Ni action by matching with the voltage polarity conversion, polarity conversion frequency and polarity conversion work period modulation of the electric power of the Ni voltage waveform, so as to achieve more partition time-sharing function control.
In addition to outputting power in the voltage polarity inversion manner in different time periods, the power supply control box system 10 may also have reversed polarities, for example, when three divisions are used: the power is output sequentially with negative polarity, positive polarity, negative polarity and last power cut-off, or sequentially with positive and negative polarity modulating frequencies F1, F2 and F3 and last power cut-off, or sequentially with positive and negative polarity modulating Duty cycles Duty1, duty2 and Duty3 and last power cut-off; if the garden light control function is to add brightness, light color or other functions besides lighting and turning off, the control power output by the power supply control box system 10 may adopt a polarity inversion frequency and duty cycle combination mode as required, for example: f1& Duty1, F2& Duty1, F3& Duty2, and finally turn off the power, wherein the conversion frequencies F1, F2, F3 represent the first, second, and third time-division respectively, and the Duty cycles Duty1, duty2 represent 100% brightness, 30% brightness respectively, so that the garden lamp 30 that is lighted at the first time-division, the garden lamp 30 that is lighted at the second time-division is fully lighted, the third time-division further is lighted, a dimming unit is built in the garden lamp 30, the lamp is turned to 30% brightness, and the lamp remains fully lighted without the dimming unit.
To illustrate the innovative content and features of the present invention, several embodiments are simplified and omitted below, and the light sensing circuit of the night detection unit and the timer circuit of an internal timer unit are disposed in a power supply control box system 10, each garden lamp 30 is installed in a separate garden lamp or group control device according to the requirements of the installation region, and the required function modes are selected according to the different voltage attributes of the output of the power supply box control system 10, including the ways of changing the power transmission polarity, modulating the positive and negative polarity conversion frequency, and/or modulating the positive and negative polarity duty cycle, so as to control the lighting and lighting time of the garden lamp 30 in different regions, and other PIR control units with functions such as movement detection (PIR) are further enlarged and integrated. The invention is not limited to the combination of these embodiments, and is further described with reference to the accompanying drawings, in which:
two-division time-sharing functional embodiment of garden light:
an embodiment of a two-division time-sharing selection function of garden lights is provided for each garden light in the garden light control system of the present invention, and a user can optionally select one of two functions of turning on the garden light from night to Dawn (i.e. turning on the garden light at night and turning off the garden light at daytime, also called Dusk to Dawn, D/D function), or turning off the garden light after the time set by the Timer circuit, so that a plurality of garden lights in a garden form two garden light groups with different functions, and the following description describes an embodiment of the present invention:
referring to fig. 1, a block diagram of a two-zone function embodiment of a garden lamp control system according to the present invention is shown, and the preferred embodiment of the present invention comprises a power supply control box system 10, wherein the power supply control box system 10 is used for receiving power from a power source 20, and the power supply control box system 10 is connected to a plurality of garden lamps 30 through a power supply line 40, and each garden lamp 30 can enable a user to select the D/D function or the Timer function according to the installation area or the application requirement thereof, so as to realize time-division zone control of illumination.
Referring to fig. 2 again, a functional block diagram of the power supply control box system 10 according to the present invention is shown, wherein the power supply 20 of the main power circuit is connected to a polarity switching circuit 12 through a power supply preparation circuit 11, and is transmitted to a power output terminal 13 for being connected to an external garden lamp 30 through the power supply line 40; the power supply control box system 10 implements a central control circuit 14, receives the current and voltage of the load loop, and the information of a light sensing circuit 15 and a timer circuit 16, and comprehensively judges the light control time through the central control circuit 14, so as to control the polarity switching circuit 12 to output the power required by the garden lamp 30, and meanwhile, utilizes polarity conversion to match with the circuit of the garden lamp 30, thereby achieving the function of time-sharing and zone-division illumination.
As shown in fig. 3, a block diagram of an internal circuit of a garden lamp 30 is shown, and the garden lamp 30 is mainly composed of a polarity/pulse detecting 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 two alternative paths of limited positive polarity (positive polarity in this embodiment, or limited negative polarity in this embodiment) and unlimited polarity; wherein the lamp circuit 32 is comprised primarily of a conventional light fixture, one or more LED lamps; the selection switch 33 (Change Over Switch) is used for providing the user with the function mode (D/D function or Timer function) switching in advance after connecting the garden lamp 30 to the power supply line 40; alternatively, as shown in fig. 4, the selector switch 33 may be replaced by a connector 34.
Referring to fig. 5, the protocols of the D/D function, the Timer function and the power polarity conversion in this embodiment are shown in fig. 6, and the power voltage polarity sent by the power supply control box system 10 is shown in fig. 6; after entering the night, the system refers to the information of the photo sensing circuit 15 and the timer circuit 16, and makes the central control circuit 14 control the polarity switching circuit 12 to output positive polarity voltage (first voltage waveform) to the power supply circuit (power supply line 40), at this time, all garden lamps 30 will obtain power to execute the first action of lighting the lamps no matter the selection switch 33 switches to the limited positive polarity passage or the unlimited polarity passage; for example, the selection switch 33 of one garden lamp 30 switches to a first path that passes a limited positive polarity, and the selection switch 33 of the other garden lamp 30 switches to a second path that passes an unlimited positive polarity, and the first power signal of positive polarity can cause both garden lamps 30 to light. When the time of the timer circuit 16 of the power supply control box system 10 reaches t1 (for example, at midnight 0), the negative polarity voltage (second voltage waveform) is transmitted; the selection switch 33 of the first garden lamp 30 switches the first path passing at the limit positive polarity at this time, and the lamp circuit 32 cannot form a current path to turn off the lamp because the voltage polarity is changed; the selection switch 33 of the second garden lamp 30 is switched to the second path with the unlimited polarity, and is not limited by the polarity of the power voltage, and can still continuously light until the light sensing circuit 15 of the power supply control box system 10 detects dawn light t2, and notifies the power supply control box system 10 to uniformly stop delivering power, i.e. turn off all garden lamps 30.
Fig. 7 (a) and 7 (b) are two examples of the internal circuit of the garden lamp 30 of the present embodiment (but the present invention is not limited to this circuit mode), and the protocol of the present embodiment is described in the foregoing paragraphs and fig. 5, in which the selection switch 33 of the garden lamp 30 switches to the limited positive polarity pass path, i.e. selects the lamp to be the "Timer" control function, and the path is routed from the power supply line 40, as in fig. 7 (a), through a series diode and the selection switch 33 inside the polarity/pulse detection circuit 31, and then is connected to the lamp circuit 32, when the central control circuit 14 outputs the positive polarity voltage (the first voltage waveform), the diode inside the polarity/pulse detection circuit 31 is turned on in the forward direction, and the lamp is allowed to be lighted; or the lamp circuit 32 as shown in fig. 7 (b), wherein the polarity/pulse detecting circuit 31 is integrated to the lamp circuit 32 by utilizing the unidirectional conduction and light-emitting characteristics of the LED in fig. 7 (b), and is particularly suitable for the LED lamp circuit, and the power is turned on by the forward conduction of the left LED. When the power supply control box system 10 turns to send out the negative voltage (the second voltage waveform), the diode inside the polarity/pulse wave detection circuit 31 in fig. 7 (a) becomes non-conductive in the reverse direction, and turns off the lamp; whereas the lamp circuit 32 of fig. 7 (b) also turns the only left LED route back on and turns the lamp off. The selection switch 33 is switched to the non-polarity-limiting pass path, i.e. the lamp is selected to be "D/D" control function, the internal path of the polarity/pulse wave detection circuit 31 in fig. 7 (a) is not limited by the polarity of the power supply voltage, or the lamp circuit 32 in fig. 7 (b) can be turned on by the right LED route to turn on the lamp, so that the lamp can be continuously turned on until dawn, and then the power supply control box system 10 stops delivering power to turn off the lamp.
The power for the device of the present invention is not limited to the dc system, but is also applicable to the ac system, as shown in fig. 8 (a), the general ac power waveform is full-wave rectified by the power supply preparation circuit 11 inside the power supply control box system 10, then the positive voltage is sent out according to the above principle when the power supply is black, and after the time t1 set by the timer circuit 16, the power supply control box system 10 is converted into the negative voltage (second voltage waveform), as shown in fig. 8 (b), so that a part of garden lamps 30 are turned off (i.e. lamps with positive polarity are selected); the remaining garden lamps 30 are turned off uniformly until the light sensing circuit 15 of the power supply control box system 10 detects dawn light t2, and the operation procedure is the same as the above-mentioned dc system.
The above embodiments can be seen to improve the innovative spirit of the garden lamp control system of the present invention, and the same set of garden lamp device can only select all garden lamps to perform D/D function or Timer function.
Multi-partition functional embodiment:
the principle of the two partition function embodiments of the D/D function and the Timer function is extended, and the present invention can divide each time-sharing period by means of the polarity conversion times, different positive and negative polarity conversion frequencies or different positive and negative polarity duty cycles of the voltage of the power supply control box system 10, so as to increase more multiple time-sharing partition functions, and the following multi-partition function embodiment illustrates three partition functions of Timer1, timer2 and D/D, and adds a Timer function option compared with the previous embodiment.
Firstly, the embodiment is described by taking the number of voltage polarity inversion as an example, the polarity inversion of the voltage sent from the power supply control box system 10 is shown in fig. 9, and fig. 10 is a block diagram of a multi-partition function embodiment, and the circuit of the garden lamp 30 is composed of a polarity/pulse wave detection circuit 31, a selection switch 33, a switch circuit 35 and a lamp circuit 32; as shown in fig. 15, when the power supply 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 detecting that the first positive voltage polarity outputted by the power supply control box system 10 is converted into negative voltage (second voltage waveform), the t1 output terminal thereof is converted into output disable signals, the rest t2 and D/D output terminals still maintain output enable signals, when detecting that the negative voltage outputted by the power supply control box system 10 is converted into positive voltage again, the t2 output terminal thereof is also converted into output disable signals, and the t1 output terminal still maintains output disable signals, and the D/D output terminal still maintains output enable signals; the switch circuit 35 is configured to select the t1, t2 or D/D output signal of the polarity/pulse wave detection circuit 31 according to the switching position of the selection switch 33, and control whether the power output by the power supply control box system 10 passes through the switch circuit 35 according to the received enabling signal or non-enabling signal, so that the LED lamp (or the conventional bulb) of the lamp circuit 32 is turned on or off.
In the above description, referring to the multi-partition function protocol for converting the polarity of the power voltage in fig. 16, when the power supply control box system 10 detects that the light sensing circuit 15 is in the night, the power supply control box system 10 sends the positive polarity voltage, at this time, no matter the user switches the selection switches 33 of all the garden lamps 30 at t1, t2 or D/D function options shown in fig. 10, because the t1, t2 and D/D output terminals all output the enable signals, the switch circuits 35 are activated, so that the lamp circuits 32 obtain the power to turn on. Thereafter, when the time reaches t1, the power supply control box system 10 switches to send out negative voltage (second voltage waveform) (as shown in fig. 9), at this time, the selection switch 33 of the garden lamp 30 switches to the t1 function, and the output end of t1 switches to output the disable signal, so that the switch circuits 35 are disconnected, and the garden lamp 30 selected for t1 is powered off; while other garden lamps 30 with the function of t2 or D/D are selected, the switch circuit 35 maintains the on-state because the output ends of t2 and D/D still maintain the output enabling signals, so that the garden lamps 30 are continuously lighted. Thereafter, when the time reaches t2, the power supply control box system 10 switches to send out positive voltage, and at this time, the selection switch 33 of the garden lamp 30 switches to the t2 function, and the switch circuits 35 are turned off due to the t2 output end switching to output the disable signal, so that the garden lamp 30 with the selected t2 function is powered off. The D/D function garden lamp 30 is selected by the selection switch 33, and the D/D output terminal thereof still maintains the output enable signal, so that the switch circuit 35 is controlled to be continuously turned on, and the lamp is continuously turned on until the power supply control box system 10 detects dawn day t3, and stops sending power to the power supply line 40, thereby turning off all lamps.
Embodiments of the conversion frequency and conversion duty cycle:
the above embodiment describes that the time-sharing partition control is performed by changing the voltage polarity of the power supply in different periods, and in the same way, the same function control purpose can be achieved by changing different polarity changing frequencies or different duty cycle modes in different periods, for example, the above three time-sharing multi-partition function embodiments, in which the first power signal, the second power signal and the third power signal are changed to output voltage waveforms with low, middle and high three different polarity changing frequencies, for example, three different frequencies of 1Hz, 5Hz and 10H, respectively, as shown in fig. 11 (a); or as shown in fig. 11 (b), the voltage waveforms of 50%, 75% and 100% three different positive and negative polarity duty cycles are respectively output in three periods. The polarity/pulse detection circuit 31 of the garden lamp 30 is also changed to a detection circuit capable of identifying the polarity conversion frequency of the voltage, or a detection circuit capable of identifying the positive and negative polarity duty cycles, wherein the polarity/pulse detection circuit detects the conditions and the three-time power signal relationship, as shown in the protocol of the multi-partition functional embodiment of fig. 17 for converting the polarity frequency of the power voltage and the protocol of the multi-partition functional embodiment of fig. 18 for converting the polarity duty cycle of the power voltage, so that the three periods t1, t2 and t3 can be determined according to the identification result of the polarity/pulse detection circuit 31.
In light of the above description, during the period from night time to time t1, all of the garden lights 30 will have the switch circuit 35 activated, regardless of whether the user switches their selection switch 33 to the t1, t2 or D/D path, the power control box system 10 converts to output the first power signal, so that the light circuit 32 gets power to turn on the lights. When the time reaches t1, the power supply control box system 10 converts the second power signal (different polarity conversion frequency or different working period), wherein the selection switch 33 of a part of garden lamps 30 is switched on the t1 path, the output end t1 is detected by the polarity/pulse wave detection circuit 31 to be not in the output enabling condition range and no longer outputs the enabling signal due to the voltage conversion frequency or working period of the second power, so that the switch circuits 35 are disconnected, the lamp circuits 32 are powered off, and the other garden lamps 30 of the t2 or D/D paths are continuously lighted. When the time continues to reach t2, the power supply control box system 10 converts the third power signal to output, at this time, the selection switch 33 switches the garden lamp 30 at t2, the switching circuit 35 thereof stops sending power and turns off all garden lamps when the power supply control box system 10 detects dawn light t3 because the voltage conversion frequency or the duty cycle of the third power, the polarity/pulse detection circuit 31 detects that the result is not in the range of the output enabling condition, the lamp circuit 32 does not output the enabling signal any more, and the garden lamp 30 of the D/D path is selected to be turned off. Similarly, by changing the voltage polarity, the positive-negative polarity changing frequency, or the positive-negative polarity changing duty cycle of the power supply at more different time periods, the garden lamps 30 can be controlled to select and perform more time-division-area lighting functions.
The function control device is independent of the garden light external embodiment:
referring to fig. 12, the function selecting and polarity identifying unit is independent of the garden lamp, and the garden lamp circuit in the foregoing embodiment of the present invention includes the polarity/pulse detecting circuit 31, the selecting switch 33, the switching circuit 35 and the lamp circuit 32, wherein the polarity/pulse detecting circuit 31, the selecting switch 33 and the switching circuit 35 can be separated into a function control device 50A, and the function control device 50A is installed outside the garden lamp 30 and is connected between the power supply line 40 and the garden lamp 30 outputted from the power supply control box system 10, so that the circuit of the garden lamp 30 is simpler and simpler, and the uniformity of the garden lamp circuit is facilitated.
