[0030] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0031] The following combination Figures 1 to 7 The isolation controller, lighting control device and lighting system of the present invention are described.

[0032] Figure 1 This is one of the structural diagrams of the isolation controller provided by the embodiment of the present invention, such as Figure 1 As shown, the isolation controller 100 includes: a mechanical switching circuit 110 , a software switching circuit 120 , a control module 130 and an isolation circuit 140 .

[0033] The mechanical switch circuit 110 includes a mechanical hardware switch unit 111, one end of which is used to connect to either a neutral wire or a live wire, and the other end of which is connected to a power ground. The mechanical switch circuit 110 is connected to the control module 130 and is used to output a first switching signal to the control module 130.

[0034] The software switch circuit 120 is connected to the control module 130 and is used to output a second switch signal to the control module 130;

[0035] The control module 130 is configured to receive one or both of the first switch signal and the second switch signal, and output a switch control signal;

[0036] The isolation circuit 140 includes a rectifier bridge circuit 141 . The rectifier bridge circuit 141 is connected to the live wire and the neutral wire. The isolation circuit 140 forms a loop with the mechanical switch circuit 110 via the rectifier bridge circuit 141 .

[0037] Specifically, in order to overcome the defect in the related art that the isolation controller cannot be arbitrarily connected to the L line or the N line to realize the hardware switch, and compared with the situation in the related art where one side of the mechanical hardware switch unit is connected to the neutral line and the other side is connected to the live line, resulting in the neutral line and the live line cannot be connected reversely, in the embodiment of the present invention, the mechanical hardware switch unit 111 detects that the primary side is connected to the power ground of the power supply, and uses a rectifier bridge to achieve that regardless of whether the mechanical hardware switch unit 111 is connected to the L line or the N line, the on-off switch signal can be detected.

[0038] Specifically, in order to overcome the defect that the isolation controller in the related art cannot realize the dual control function of software and hardware, in the embodiment of the present invention, a software switch circuit 120 is set to output a second switch signal to the control module 130, and / or a first switch signal is output to the control module 130 through a mechanical switch circuit 110. When the control module 130 receives the first switch information and / or the second switch signal, it can determine the state of the controlled load based on the received first switch information and / or second switch signal, generate a switch control signal and output it, thereby realizing the function of dual control of the same load by a software wireless switch and a hardware software switch.

[0039] The isolation controller provided by the present invention connects the mechanical hardware switch unit in the mechanical switch circuit to the power ground and uses the rectifier bridge circuit and the isolation circuit to form a loop, so that regardless of whether the mechanical switch circuit is connected to the neutral wire or the live wire, the hardware control switch can be realized by outputting a first switch signal, thereby reducing the difficulty of installation. In addition, by setting the software switch circuit to send a second switch signal to the control module, software control of the switch is realized, that is, a dual control function is realized, thereby improving the convenience and reliability of switch control.

[0040] In some embodiments, the mechanical switch circuit 110 further includes an optocoupler unit 112 , which is connected to the control module 130 . The optocoupler unit 112 is used to sense the level signal from the mechanical hardware switch unit 111 and output the first switch signal to the control module 130 .

[0041] Specifically, the mechanical switch circuit 110 may include an optocoupler unit 112. When the mechanical switch changes from open to closed, the optocoupler unit 112 can sense the high and low level signals from the mechanical hardware switch unit 111, and generate a first switch signal for representing that the mechanical switch is closed, and send it to the control module 130; when the mechanical switch changes from closed to open, the optocoupler unit 112 will no longer sense the level signal, and can generate a first switch signal for representing that the mechanical switch is open, and send it to the control module 130.

[0042] In some embodiments, the mechanical hardware switch unit includes a mechanical switch and a rectifier, one end of the mechanical switch is used to connect to a neutral line or a live line, and the other end of the mechanical switch is connected to a power ground through the rectifier.

[0043] Specifically, the mechanical hardware switch unit may include a mechanical switch and a rectifier. The rectifier may convert an AC signal from the mechanical switch into a DC signal to achieve a rectification function and protect other electronic components.

[0044] In some embodiments, the rectifier includes a FR107W diode.

[0045] Specifically, the FR107W diode is a fast recovery diode with a rectifier function. The FR107W diode can convert AC signals into DC signals. This fast recovery diode has a short recovery time and can quickly return to the forward conduction state, making it suitable for high-frequency rectification applications.

[0046] Specifically, the FR107W diode also offers low reverse recovery time and low reverse leakage current, and can be used to protect other electronic components from high voltage, high current or high frequency electromagnetic interference.

[0047] Specifically, FR107W diodes are also used in power supply circuits as protection components for switching circuits to prevent voltage interference or overcurrent from damaging the power supply circuits.

[0048] Figure 2 Schematic diagram of a mechanical switch circuit provided by an embodiment of the present invention, such as Figure 2 As shown, the mechanical hardware switch unit of the mechanical switch circuit includes a mechanical switch S1, an optional terminal CON 1, and a rectifier D5, whose model is FR107W. The FR107W fast recovery diode plays multiple roles in electronic circuits, such as rectification, protection, and switching. The mechanical hardware switch unit includes a mechanical switch and an FR107W diode; one end of the mechanical switch is used to connect to either the neutral wire or the live wire, and the other end of the mechanical switch is connected to the power ground through the FR107W diode, which can effectively protect various electronic components in the circuit.

[0049] It should be noted that the present invention does not limit the parameters of the components in the mechanical switch circuit 110. All parameters that enable the mechanical switch circuit 110 to achieve the above functions or enable the modules in the mechanical switch circuit 110 to achieve the above corresponding functions are applicable to the present invention.

[0050] In some embodiments, the software switch circuit includes a wireless Bluetooth unit, and the input of the wireless Bluetooth unit includes a Bluetooth signal from a remote control or an electronic device, and the electronic device is installed with the switch control software.

The user can operate the remote control or electronic device, such as clicking the light on or off button on the interface of the switch control software in the electronic device, to enable the remote control or electronic device to send a Bluetooth signal to the wireless Bluetooth unit, so that the wireless Bluetooth unit sends a second switch signal to the control module.

[0052] In some embodiments, the control module includes a single chip microcomputer or a microprocessor.

[0053] Figure 4 is a schematic diagram of a control module provided by an embodiment of the present invention, such as Figure 4 As shown, the control module may be a single chip microcomputer or a microprocessor, for example, a microcontroller unit (MCU) or a single chip microcomputer (Single Chip Microcomputer) or a single chip microcomputer.

[0054] The software switch circuit 120 outputs a second switch signal to the single-chip microcomputer or microprocessor, and / or the mechanical switch circuit 110 outputs a first switch signal to the single-chip microcomputer or microprocessor. When the single-chip microcomputer or microprocessor receives the first switch information and / or the second switch signal, it can determine the state of the controlled load based on the received first switch information and / or the second switch signal, generate and output a switch control signal, and realize the function of dual control of the same load by the software wireless switch and the hardware software switch.

[0055] In some embodiments, the isolation circuit 140 includes a primary circuit 141 and a secondary circuit 142 , the rectifier bridge circuit is connected to the primary circuit, and the primary circuit is configured to refract voltage to the secondary circuit after being powered on.

[0056] Specifically, isolation circuits are used to completely transfer signals or power from one circuit to another while achieving electrical isolation, even if there is a potential difference between the two circuits. The primary and secondary circuits are two key components of an isolation circuit. The primary circuit is typically the input, receiving the signal or power source. In an isolation circuit, the primary circuit is typically physically separated from the external circuit by an isolation barrier (such as a transformer or optocoupler), preventing direct current or signal transmission. The primary circuit is responsible for receiving and transmitting energy. The secondary circuit is typically the output, converting the signal or power transmitted from the primary into a final output signal or power. Communication between the secondary and primary circuits occurs through an isolation barrier (such as a transformer or optocoupler), maintaining electrical isolation between the two circuits. In an isolation circuit, transmission between the primary and secondary sides occurs through a physically isolated medium. This isolation can be achieved using various technologies, such as transformers, optocouplers (photocouplers), or magnetic couplers. These isolation technologies prevent electrical noise, potential differences, and other issues from propagating between the primary and secondary sides, achieving effective isolation and protection.

[0057] In the embodiment of the present invention, the primary circuit winding can refract voltage to the secondary circuit after being energized.

[0058] In some embodiments, the secondary circuit is connected to the software switching circuit for supplying power to the software switching circuit; and / or the secondary circuit is connected to the control module for supplying power to the control module.

[0059] Figure 5 This is a second structural diagram of the isolation controller provided by an embodiment of the present invention, such as Figure 5 As shown, the secondary circuit can be connected to the software switch circuit and / or to the control module; after the circuit is powered on, the secondary circuit of the isolated power supply outputs a constant voltage of 5V, which can power the control module and / or the wireless Bluetooth unit to realize the AC-DC function.

[0060] It should be noted that the present invention does not limit the parameters of the components in the isolation controller. All parameters that enable the isolation controller to achieve the above functions or enable the circuits or modules in the isolation controller to achieve the above corresponding functions are applicable to the present invention.

[0061] In an embodiment of the present invention, if the mechanical switch S1 in the lighting control device remains in a closed state and the load is in an on state, the user presses S2 through an electronic device or a remote control to turn off the load, and pin 7 of the microcontroller outputs a close signal (switch control signal); if the mechanical switch S1 in the lighting control device remains in an open state and the load is in an off state, the user presses S2 through an electronic device or a remote control to turn on the load, and pin 7 of the microcontroller outputs an open signal (switch control signal); thereby realizing the dual control function of software and hardware mechanical switches.

[0066] The remote controller or electronic device is used to send a Bluetooth signal to the lighting control device.

[0067] In an embodiment of the present invention, a remote control or an electronic device is used to send a Bluetooth signal to the lighting control device. After the lighting control device receives the Bluetooth signal, it can control the lighting device to be turned on and off through a switch control signal, or after the mechanical switch in the lighting control device is closed or opened, it can also control the lighting device to be turned on and off through a switch control signal.
