[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0028] The present application discloses a lighting control device and a lamp, which are used to send a control signal received by a wireless communication technology (Wireless Fidelity, WIFI) circuit to a driving circuit via a Bluetooth circuit, thereby realizing long-distance transmission of the control signal. Detailed descriptions are given below.

[0029] In order to better understand the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below.

[0030] See also Figure 1 , Figure 1 Schematic diagram of the structure of a lamp disclosed in the embodiment of the present application. Figure 1 As shown, the lamp may include a power supply, a Bluetooth circuit and a light-emitting device.

[0031] The power supply can be connected to the Bluetooth circuit and the light-emitting device respectively to power the Bluetooth circuit and the light-emitting device to ensure the normal operation of the lamp. The Bluetooth circuit can receive control signals from the user terminal (such as a smart phone, tablet computer, etc.) that is successfully paired with it, and control the switch, brightness, color change and other functions of the light-emitting device according to these signals. Users can use Bluetooth technology to control lamps, such as turning on / off lights, adjusting brightness or changing light colors, thereby meeting basic needs for light control in daily life.

[0032] However, since Bluetooth technology cannot directly access the Internet, users cannot achieve remote control through the Internet. For example, users cannot adjust the status of lights at home when they are away, which limits the application scope and flexibility of lamps. Secondly, due to the lack of Internet connection, Bluetooth circuits cannot receive the latest software updates and firmware upgrades, and cannot download the latest configuration data, scene settings or other data that users may need from the Internet, which limits the scalability of lamp functions.

[0033] In order to solve the above problems, the present application designs a lighting control device, which can send the control signal received by the WIFI circuit to the driving circuit through the Bluetooth circuit, thereby realizing the long-distance transmission of the control signal.

[0034] See also Figure 2 , Figure 2 Schematic diagram of the structure of a lighting control device disclosed in the embodiment of the present application. Figure 2 As shown, the lighting control device may include a WIFI circuit, a Bluetooth circuit and a driving circuit.

[0035] The first end of the WIFI circuit is connected to the first end of the Bluetooth circuit, the second end of the Bluetooth circuit is connected to the first end of the driving circuit, the second end of the driving circuit is connected to the light-emitting device, the second end of the WIFI circuit is the signal input end of the light control device, and the third end of the WIFI circuit is the power input end of the light control device.

[0036] The WIFI circuit can receive the first control signal and send the first control signal to the Bluetooth circuit through the first end of the WIFI circuit. The Bluetooth circuit can send the received first control signal to the driving signal through the second end of the Bluetooth circuit. The driving circuit can control the lighting effect of the light-emitting device according to the first control signal, thereby realizing remote control of the light-emitting device.

[0037] The first control signal may be a control signal for controlling the light emitting device to achieve different lighting effects. The first control signal may control the switch, brightness, color, etc. of the light emitting device.

[0038] The first control signal may be a control signal sent by a user through a user device (such as a smart phone, a tablet computer, etc.) bound to the WIFI circuit.

[0039] For example, assuming that the light-emitting device is a lamp in the living room, the user wants to turn on the lamp in the living room before returning home and adjust the light color of the lamp to yellow. The user can send a first control signal to the WIFI circuit through a user device bound to the WIFI circuit in the lighting control device. The first control signal is used to instruct to turn on the lamp in the living room and adjust the light color of the lamp to yellow. After receiving the first control signal, the WIFI circuit can send the first control signal to the Bluetooth circuit. The Bluetooth circuit can send the first control signal to the drive circuit. The drive circuit can turn on the lamp in the living room according to the first control signal and adjust the light color of the lamp to yellow.

[0040] The WIFI circuit can also receive a third control signal, and send the third control signal to the Bluetooth circuit through the first end of the WIFI circuit. The Bluetooth circuit can upgrade the Bluetooth circuit according to the received third control signal.

[0041] The third control signal may be a control signal for upgrading the Bluetooth circuit.

[0042] The third control signal may be a control signal sent by a user to the WIFI circuit via the Internet.

[0043] For example, the developer releases update data of the Bluetooth firmware to increase the security of control signal transmission. The WIFI circuit can receive the third control signal and send the third control signal to the Bluetooth circuit, and the third control signal can upgrade the Bluetooth firmware in the Bluetooth circuit. The Bluetooth circuit can upgrade the Bluetooth firmware according to the third control signal to ensure the security of lighting control.

[0044] In some embodiments, the WIFI circuit may also be connected to a driving circuit. The WIFI circuit may also directly send the received first control signal to the driving circuit, and the driving circuit may control the light emitting device according to the first control signal, thereby realizing remote control of the light emitting device.

[0045] For example, suppose that a user needs to turn off all the lamps in the home, but the Bluetooth circuit fails at this time. The user can send a first control signal to the WIFI circuit through a user device bound to the WIFI circuit, and the first control signal is used to instruct to turn off all the lamps in the home. The WIFI circuit can directly send the received first control signal to the drive circuit. The drive circuit can turn off all the lamps in the home according to the first control signal without relying on the Bluetooth circuit.

[0046] The driving circuit may be a single Schmitt trigger buffer. The single Schmitt trigger buffer may be packaged in SOT-23 or in other ways. The model of the single Schmitt trigger buffer may be AiP74LVC1G17 or other models with equivalent functions.

[0047] It should be understood that the connection in the present application may be an electrical connection.

[0048] exist Figure 1 The described lighting control device includes a WIFI circuit, a Bluetooth circuit and a driving circuit. The first end of the WIFI circuit is connected to the first end of the Bluetooth circuit, the second end of the Bluetooth circuit is connected to the first end of the driving circuit, the second end of the driving circuit is connected to the light-emitting device, the second end of the WIFI circuit is the signal input end of the lighting control device, and the third end of the WIFI circuit is the power input end of the lighting control device; the WIFI circuit is used to receive a first control signal and send the first control signal to the Bluetooth circuit; the Bluetooth circuit is used to send the first control signal to the driving circuit; the driving circuit is used to control the lighting effect of the light-emitting device according to the first control signal. It can be seen that the WIFI circuit can receive the first control signal, and then send the first control signal to the first end of the Bluetooth circuit, and the Bluetooth circuit can send the first control signal to the driving circuit, so that the driving circuit can control the lighting effect of the light-emitting device according to the first control signal. Since the WIFI technology can realize long-distance transmission and the Bluetooth technology can realize short-distance transmission with low power consumption, when the WIFI circuit receives the first control signal from a long distance, the first control signal can be sent to the Bluetooth circuit, and the first control signal is sent to the driving circuit through the Bluetooth circuit, so that the long-distance transmission of the control signal can be realized.

[0049] See also Figure 3 , Figure 3 FIG. 1 is a schematic diagram of the structure of another lighting control device disclosed in an embodiment of the present application. Figure 3 As shown, the lighting control device may further include a micro controller unit (MCU).

[0050] The first end of the MCU is connected to the third end of the Bluetooth circuit, and the second end of the MCU is the power input end of the lighting control device.

[0051] The MCU can receive the second control signal and send the second control signal to the Bluetooth circuit through the first end of the MCU. The Bluetooth circuit can send the second control signal to the driving circuit through the second end of the Bluetooth circuit. The driving circuit can control the lighting effect of the light-emitting device according to the second control signal.

[0052] The second control signal may be a control signal for controlling the light emitting device to achieve different lighting effects. The second control signal may control the switch, brightness, color, etc. of the light emitting device.

[0053] The second control signal may be a control signal sent by a user through a physical interface (a button or a touch screen) connected to the MCU.

[0054] In some embodiments, the MCU may further include a serial communication module. The serial communication module is connected to the MCU.

[0055] The serial communication module can enable the MCU to support multiple serial communication protocols, including Universal Asynchronous Receiver Transmitter (UART), Serial Peripheral Interface (SPI), etc.

[0056] MCU can exchange data with external devices (such as sensors, other MCUs, computers, etc.) through serial communication modules. Through serial communication modules, MCU can connect to more devices and networks, which can improve the scalability of MCU. For example, you can connect to a network module through a serial interface, so that the MCU can send and receive Internet data.

[0057] See also Figure 4 , Figure 4 Schematic diagram of a WIFI circuit disclosed in the embodiment of the present application. Figure 4 As shown, the WIFI circuit may include a WIFI switch module and a WIFI module.

[0058] The signal input end of the WIFI switch module is connected to the Bluetooth circuit, the output end of the WIFI switch module is connected to the power input end of the WIFI module, the output end of the WIFI module is connected to the Bluetooth circuit, the signal input end of the WIFI module is the second end of the WIFI circuit, and the power input end of the WIFI module is the third end of the WIFI circuit.

[0059] When the WIFI module needs to be turned on, the Bluetooth circuit can receive a WIFI enable signal and send the WIFI enable signal to the WIFI switch module. The WIFI switch module can control the WIFI module to enter a working state according to the WIFI enable signal. The WIFI module can receive a first control signal and send the first control signal to the Bluetooth circuit.

[0060] The WIFI enable signal may be a control signal for controlling the WIFI module to enter a working state, that is, controlling the WIFI circuit to receive a first control signal and send the first control signal to the Bluetooth circuit.

[0061] The WIFI enabling signal may be a control signal sent by a user through a user device (such as a smart phone, a tablet computer, etc.) bound to a Bluetooth circuit.

[0062] See also Figure 5 , Figure 5 Schematic diagram of the structure of a WIFI switch module disclosed in the embodiment of the present application. Figure 5 As shown, the WIFI switch module includes a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, a fifth resistor R5, a first capacitor C1, a first switch device Q1 and a second switch device Q2, wherein:

[0063] One end of the first resistor R1 is connected to the Bluetooth circuit, the other end of the first resistor R1 is respectively connected to the first end of the first switch device Q1 and one end of the second resistor R2, the second end of the first switch device Q1 is connected to one end of the third resistor R3, the third end of the first switch device Q1 and the other end of the second resistor R2 are respectively grounded, the other end of the third resistor R3 is respectively connected to one end of the fourth resistor R4, one end of the first capacitor C1 and the first end of the second switch device Q2, the second end of the second switch device Q2 is respectively connected to the other end of the fourth resistor R4, the other end of the first capacitor C1 and one end of the fifth resistor R5, the third end of the second switch device Q2 is respectively connected to the other end of the fifth resistor R5 and the power input end of the WIFI module, and the second end of the second switch device Q2 is the power input end of the WIFI switch module.

[0064] The first switch device Q1 may be a transistor, or other switch devices for controlling circuit switching. Figure 5 The description is made by taking the first switch device Q1 as a triode as an example.

[0065] When the first switching device Q1 is a transistor, the base of the transistor is the first end of the first switching device Q1, the collector of the transistor is the second end of the first switching device Q1, and the emitter of the transistor is the third end of the first switching device Q1.

[0066] The second switch device Q2 may be a metal oxide semiconductor (MOS) tube, or may be other switch devices with equivalent functions. Figure 5 The description is made by taking the first switch device Q1 as a MOS tube as an example.

[0067] When the second switch device Q2 is a MOS tube, the gate of the MOS tube is the first end of the second switch device Q2, the drain of the MOS tube is the second end of the second switch device Q2, and the source of the MOS tube is the third end of the second switch device Q2.

[0068] When the WIFI module needs to be turned on, the Bluetooth circuit can receive the WIFI enable signal and send the WIFI enable signal to the WIFI switch module. The WIFI enable signal can be transmitted to the first end of the first switch device Q1 through the first resistor R1, so that the first switch device Q1 is turned on. After the first switch device Q1 is turned on, the first end of the second switch device Q2 can obtain a suitable level through the third resistor R3 and the fourth resistor R4 after voltage division, thereby turning on the second switch device Q2, thereby powering the WIFI module and controlling the WIFI module to enter the working state.

[0069] The first resistor R1 serves as a current limiting protection resistor of the first switching device Q1 , and can limit the current flowing to the first switching device Q1 , thereby preventing the first switching device Q1 from being damaged by an excessively high current.

[0070] The second resistor R2 can provide a default level for the first end of the first switch device Q1, which can ensure that the first end of the first switch device Q1 is maintained at an appropriate level in the absence of an input signal (such as a WIFI enable signal), thereby preventing the first switch device Q1 from accidentally turning on.

[0071] The third resistor R3 and the fourth resistor R4 may form a voltage divider circuit, which may reduce the high voltage impact on the first end of the second switch device Q2 and prevent the second switch device Q2 from being damaged due to excessive voltage.

[0072] The first capacitor C1 is used as a delayed turn-on capacitor to extend the start-up time of the second switch device Q2 and avoid a high peak current that may be caused when the second switch device Q2 suddenly changes from a cut-off state to a fully turned-on state.

[0073] The fifth resistor R5 serves as a compatible power supply on-resistance of the second switching device Q2 and can help distribute the voltage between the second terminal and the third terminal of the second switching device Q2 to ensure that the second switching device Q2 operates within its safe operating area.

[0074] See also Figure 6 , Figure 6 : is a schematic diagram of the structure of another WIFI switch module disclosed in the embodiment of the present application. Figure 6 The WIFI switch module shown consists of Figure 5 The WIFI switch module shown is optimized. Figure 6 As shown, the WIFI switch module may further include a second capacitor C2, a third capacitor C3 and a first high-frequency magnetic bead FB1.

[0075] One end of the second capacitor C2 is connected to the second end of the second switch device Q2, and the other end of the second capacitor C2 is grounded. One end of the third capacitor C3 is connected to the third end of the second switch device Q2, and the other end of the third capacitor C3 is grounded.

[0077] One end of the first high-frequency magnetic bead FB1 is connected to the third end of the second switch device Q2 , and the other end of the first high-frequency magnetic bead FB1 is connected to the power input end of the WIFI module.

[0078] After the second switch device Q2 is turned on, the power can be transmitted to the WIFI module through the first high-frequency magnetic bead FB1. The first high-frequency magnetic bead FB1 can filter out high-frequency interference in the circuit, thereby ensuring that the WIFI module receives clean power supply.

[0079] See also Figure 7 , Figure 7 Schematic diagram of the structure of a WIFI module disclosed in the embodiment of the present application. Figure 7 As shown, the WIFI module may include a WIFI unit, a fourth capacitor C4 and a fifth capacitor C5.

[0080] One end of the fourth capacitor C4 is respectively connected to the first end of the WIFI unit and one end of the fifth capacitor C5, the other ends of the fourth capacitor C4 and the fifth capacitor C5 are respectively grounded, the second end of the WIFI unit is connected to the Bluetooth circuit, the first end of the WIFI unit is the power input end of the WIFI module, and the third end of the WIFI unit is the signal input end of the WIFI module.

[0081] The third end of the WIFI unit can receive the first control signal, and send the first control signal to the Bluetooth circuit through the second end of the WIFI unit.

[0082] The WIFI unit may be an IoT microcontroller, and the model of the IoT microcontroller may be RTL8720CF, or other models with equivalent functions.

[0083] The fourth capacitor C4 and the fifth capacitor C5 can remove the noise in the power supply from the signal path to prevent high-frequency switching noise interference.

[0084] Among them, the capacitance values ​​of the fourth capacitor C4 and the fifth capacitor C5 are different. The fourth capacitor C4 has a larger capacitance value, which can filter out low-frequency noise, smooth the lower frequency components in the voltage ripple, and provide a larger energy storage for the circuit, so that the voltage can be maintained stable when the instantaneous load changes. The fifth capacitor C5 has a smaller capacitance value, which can filter out high-frequency noise, handle higher frequency spikes, and respond quickly to high-frequency changes.

[0085] Exemplarily, the fourth capacitor C4 may be a capacitor with a capacitance value ranging from microfarad level to millifarad level, and the fifth capacitor C5 may be a capacitor with a capacitance value ranging from picofarad level to nanofarad level.

[0086] It should be understood that the fourth capacitor C4 may include one capacitor or multiple capacitors. In the case where the fourth capacitor C4 includes multiple capacitors, the fourth capacitor C4 may be formed by connecting the multiple capacitors in parallel. The fifth capacitor C5 may include one capacitor or multiple capacitors. In the case where the fifth capacitor C5 includes multiple capacitors, the fifth capacitor C5 may be formed by connecting the multiple capacitors in parallel.

[0087] See also Figure 8 , Figure 8 Schematic diagram of the structure of an MCU disclosed in the embodiment of the present application. Figure 8 As shown, the MCU may include an MCU chip, a sixth resistor R6, a seventh resistor R7, a sixth capacitor C6, a seventh capacitor C7 and an eighth capacitor C8.

The MCU can receive the second control signal and send the second control signal to the Bluetooth circuit.

[0089] The sixth resistor R6 and the sixth capacitor C6 can form an RC circuit for the power-on reset function of the MCU. When the power of the MCU is turned on for the first time, the sixth capacitor C6 is in a discharged state. As the power is turned on, the current begins to flow to the sixth capacitor C6 through the sixth resistor R6, so that the sixth capacitor C6 begins to charge. Due to the current limiting effect of the sixth resistor R6, the voltage of the sixth capacitor C6 gradually rises, and this rising process can delay the arrival time of the reset signal. The RC circuit composed of the sixth resistor R6 and the sixth capacitor C6 can provide a stable startup environment for the MCU by delaying the release of the reset signal, ensuring that all system voltages are stable before starting to execute the program. The seventh capacitor C7 and the eighth capacitor C8 act as filter capacitors, which can make the voltage more stable.

[0090] The model of the MCU chip may be BAT32G133, or other models with equivalent functions.

[0091] See also Fig. 9 , Fig. 9 : is a schematic diagram of another MCU structure disclosed in the embodiment of the present application. Fig. 9 The MCU shown consists of Figure 8 The MCU shown is optimized. Fig. 9 As shown, the MCU may further include a ninth resistor R9 and a tenth resistor R10.

[0093] The ninth resistor R9 and the tenth resistor R10 serve as current limiting protection resistors, which can limit the current flowing to the Bluetooth circuit and protect the Bluetooth circuit from being damaged by excessive current.

[0094] After the MCU is powered on, the sixth resistor R6 and the sixth capacitor C6 can realize the reset function after the MCU is powered on, thereby increasing the stability and reliability of the system. The MCU chip can communicate with the Bluetooth chip through the ninth resistor R9 and the tenth resistor R10 via the serial communication protocol (Inter-Integrated Circuit, IIC). The ninth resistor R9 and the tenth resistor R10 serve as I 2 The current limiting protection resistor of the C communication line can protect the circuit from damage by excessive current, and at the same time can reduce noise interference during the communication process, thus ensuring the reliability of data transmission.

[0098] The antenna can receive and send Bluetooth data, for example, receive control signals sent by users. The ninth capacitor C9, the tenth capacitor C10 and the eleventh capacitor C11 can help achieve impedance matching between the antenna and the Bluetooth chip.

[0108] The power conversion circuit can convert a first direct current signal provided by the power supply into a second direct current signal, and a voltage of the second direct current signal is lower than a voltage of the first direct current signal.

[0109] Since the voltage output by most power supplies does not meet the voltage requirements of the Bluetooth circuit, WIFI circuit and / or MCU. For example, the voltage output by the power supply is usually 36V, while the operating voltage of the Bluetooth circuit, WIFI circuit and / or MCU is usually 3.3V. Therefore, the higher input voltage can be converted into the required lower voltage through the power conversion circuit to ensure that the Bluetooth circuit, WIFI circuit and / or MCU can operate safely at the correct voltage.

[0111] The output end of the switch circuit is connected to the light emitting device, the signal input end of the switch circuit is connected to the Bluetooth circuit, and the power input end of the switch circuit is the power input end of the light control device.

[0112] The Bluetooth circuit can generate a switch control signal and send the switch control signal to the switch circuit. The switch circuit can control the working state of the light emitting device according to the switch control signal.

[0113] In some embodiments, the lighting control device may further include a power supply circuit.

[0114] The output end of the power supply circuit is connected to the switch circuit and the Bluetooth circuit respectively, and the input end of the power supply circuit is the power input end of the lighting control device.

[0117] The input end of the power input module is the input end of the power supply circuit, and the output end of the power input module is the output end of the power supply circuit. The power input module can filter the electromagnetic interference in the third direct current signal to obtain the first direct current signal.

[0118] In some embodiments, the power supply circuit may further include a soft start module.

[0119] The input end of the slow start module is connected to the output end of the power input module, and the output end of the slow start module is the output end of the power supply circuit.

The insurance module can send the fourth DC signal to the slow start module when the current of the fourth DC signal does not exceed the preset current.

[0122] In the case where the light emitting device includes a plurality of light emitting units, the light control device may further include a detection circuit and a processing circuit, and the detection circuit may include a sampling resistor.

[0123] The detection circuit is respectively connected to the Bluetooth circuit, the processing circuit and the light emitting device.

[0124] The Bluetooth circuit can send a first signal to the detection circuit. The detection circuit can detect the voltage of the sampling resistor according to the first signal.

[0126] See also Fig.12 , Fig.12is a schematic diagram of the structure of another lamp disclosed in the embodiment of the present application. Fig.12 As shown, the lamp may further include a first boost circuit.

[0127] The first boost circuit can be connected between the light control device and the light emitting device. The first boost circuit can convert the fifth DC signal into a sixth DC signal, and the voltage of the fifth DC signal is less than the voltage of the sixth DC signal.

[0128] Due to the existence of impedance, the power supply will experience voltage attenuation during the transmission process. When the transmission distance is too long, the transmission voltage will attenuate to a certain extent and cannot meet the stable operation or other requirements of the back-end terminal. For example, when the transmission distance between the light control device and the light-emitting device is too long, the transmission voltage will attenuate to a certain extent, and the light-emitting device will experience abnormal phenomena such as light source color difference, flashing, etc. Therefore, the first boost circuit can be used to convert the fifth DC signal with a lower voltage into the sixth DC signal with a higher voltage to provide a suitable DC voltage for the light-emitting device.

[0129] See also Fig.13 , Fig.13 is a schematic diagram of the structure of another lamp disclosed in the embodiment of the present application. Fig.13 As shown, the lamp may further include a second boost circuit. The lighting device may include a plurality of light emitting units.

[0130] The second boost circuit may be connected between two adjacent light-emitting units. The second boost circuit may convert the seventh DC signal into an eighth DC signal, and the voltage of the seventh DC signal is lower than the voltage of the eighth DC signal.

[0131] The seventh DC signal with a lower voltage can be converted into an eighth DC signal with a higher voltage by the second boost circuit, so as to provide a suitable DC voltage for the light-emitting unit.

[0132] See also Fig.14 , Fig.14 is a schematic diagram of the structure of another lamp disclosed in the embodiment of the present application. Fig.14 As shown, the lamp may further include a third boost circuit and a fourth boost circuit. The light emitting device may include a plurality of light emitting units (only two are shown in the figure).
