[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0034] In intelligent lighting systems, multi-lamp linkage control is an important means to achieve energy saving and scene-based lighting. However, with the increase in the number of lamps and the complexity of control, multiple lamps often face problems such as signal interference and signal conflict when working together, which reduces the stability and reliability of lamp operation.

[0035] Therefore, refer to Figure 1 The present invention proposes a smart lighting fixture comprising a lighting body and a circuit board; and comprising:

[0036] The communication module 10 has a communication terminal for communicating with external devices;

[0037] The microwave module 20 is used to transmit microwave signals and receive reflected microwave signals, and to process the reflected microwave signals and output corresponding human body movement electrical signals.

[0038] The touch sensing module 30 is used to detect human touch signals and output corresponding touch control signals;

[0039] The main controller 40 is electrically connected to the communication module 10, the microwave module 20, and the touch sensing module 30, respectively;

[0040] The main controller 40 is used to send and / or receive linkage signals via the communication module 10, and to control the working state of the lamp body according to at least one of the linkage signals, the human body movement electrical signals, and the touch control signals.

[0041] The communication module 10, the microwave module 20, the touch sensing module 30, and the main controller 40 are all mounted on the circuit board, and the communication module 10, the microwave module 20, and the touch sensing module 30 are located on at least two sides of the main controller 40.

[0042] In this embodiment, the main controller 40 can be implemented using, for example, an MCU, a DSP (Digital Signal Processor), an FPGA (Field Programmable Gate Array), a PLC, or a SOC (System on Chip). The communication module 10 can be implemented using wired communication modules such as CAN or RS485, or wireless communication modules such as Bluetooth, 2.4G / 4G / 5G, or WIFI. The lamp body can be composed of an LED light source, a heat dissipation structure, and a housing. The heat dissipation structure can use an aluminum heat sink or a heat pipe design; the housing can be made of flame-retardant ABS or PC material, which has good insulation and heat dissipation performance. The circuit board, as the carrier of the various functional modules inside the lamp, can be implemented using printed circuit boards, flexible circuit boards, ceramic substrates, etc.

[0043] In this embodiment, the microwave module 20 can be implemented using a 5.8G microwave module, which emits microwaves and receives echo signals caused by human movement, thereby determining the human movement status and outputting corresponding electrical signals. Compared with traditional infrared pyroelectric sensing modules, the 5.8G microwave sensing module is smaller in size, easier to install, and does not require openings in the outer casing, making it more aesthetically pleasing and neat.

[0044] In this embodiment, the communication module 10 can be implemented using a 2.4G communication module. The communication module 10 is responsible for communicating with other external devices, such as sending linkage signals to external devices or receiving linkage signals from external devices.

[0045] In this embodiment, the touch sensing module 30 can be implemented using a capacitive touch sensing module 30. Correspondingly, a touch button can be provided on the lamp body, or a separate touch button can be provided, electrically connected to the lamp body, and installed in a location easily accessible to the user, such as a desktop or wall. Touch buttons are more aesthetically pleasing and cleaner than physical buttons, eliminating the need for openings in the casing, thus simplifying the manufacturing process and reducing costs. When the touch button is touched by the user, the touch sensing module 30 can detect the change in capacitance or resistance generated by the user's touch operation and convert it into an electrical signal. The touch sensing module 30 typically includes a sensor chip and processing circuitry for filtering, debouncing, and recognizing different touch actions (such as light touch, long press, etc.).

[0046] In this embodiment, the main controller 40 controls the working state of the lamp body based on at least one of the linkage signal, the human body movement electrical signal, and the touch control signal. For example, when a user briefly presses the touch button of the lamp, the touch sensing module 30 sends a specific touch control signal to the main controller 40. After receiving the touch control signal, the main controller 40 switches the working mode of the lamp, such as controlling the lamp to turn on or off, to achieve lamp switching control. If the user presses and holds the touch button, the touch sensing module 30 will also send a corresponding touch control signal to the main controller 40. At this time, the main controller 40 will adjust the brightness of the lamp, usually gradually increasing or decreasing the brightness. At the same time, the 5.8G microwave sensing module continuously monitors the surrounding environment. Once it detects someone approaching, it sends a human body movement electrical signal to the main controller 40. The main controller 40 turns on the lamp based on the human body movement electrical signal and sends a linkage signal to external devices, such as other lamps, via the communication module 10. When the main controller 40 of a certain lamp receives a linkage signal through the 2.4G linkage module (communication module 10), it determines whether someone is approaching and within the detection range based on the output of the 5.8G microwave sensing module. If someone is within the detection range, it controls its own lamp to turn on and sends a linkage signal to other surrounding lamps through the 2.4G linkage module to notify them in advance. This allows the main controllers 40 of other lamps to control their lights to turn on or off based on touch control signals or human movement electrical signals. Alternatively, when a lamp receives a linkage signal through the 2.4G linkage module, it controls its own lamp to turn on and sends a linkage signal to other associated surrounding lamps through the 2.4G linkage module, causing all associated lamps to turn on synchronously.

[0047] In one embodiment, assuming a multi-story residential building has multiple smart lights installed in the stairwell, these lights communicate with each other via a 2.4G linkage module. When someone goes up or down the stairs: the 5.8G microwave sensing module of the light closest to the person detects the movement and sends a movement signal to its main controller 40. Upon receiving the movement signal, the main controller 40 determines that someone is approaching and within the detection range, and controls its own light to turn on. Simultaneously, this light's main controller 40 also sends a linkage signal to other surrounding lights via the 2.4G linkage module. Lights receiving the linkage signal will have their own 5.8G microwave sensing modules check if they have also detected human movement. If someone is approaching and within the detection range, the light will turn on. To improve the user experience, lights can also turn on even if no movement is directly detected, simply by receiving the linkage signal. In this way, these lights illuminate synchronously. Understandably, if a person continues to move away from a lamp and the lamp's 5.8G microwave sensing module does not detect human movement or moves out of its detection range for an extended period, it can be set to automatically turn off after a certain period (such as a preset first duration, 3 seconds) to save energy.

[0048] In another embodiment, suppose a user gets up at night to go to the bathroom, and the path includes the bedroom, hallway, and bathroom. Upon leaving the bedroom, the bedroom lights are activated and turn on by the user triggering a touch button or by their own microwave module 20. The main controller 40 of the bedroom lights can send a linkage signal to the first light in the hallway via a 2.4G linkage module. After receiving the linkage signal, the main controller 40 of the first light in the hallway automatically turns on based on the human movement detected by its 5.8G microwave sensing module. When the user walks towards the bathroom through the hallway, each light along the way automatically turns on based on the human movement detected by its 5.8G microwave sensing module, and simultaneously sends a linkage signal to the lights ahead, causing the lights ahead to pre-light up and provide sufficient illumination. At the bathroom entrance, smart lights are also installed, which can automatically turn on based on human movement and provide necessary lighting for the user.

[0049] The combination of a 2.4G linkage module and a 5.8G microwave sensing module effectively improves the comfort and safety of the living environment while also considering energy-saving requirements. Each lamp can not only independently respond to local triggering conditions (such as touch or human body sensing) but also coordinate with other lamps. However, both the 5.8G microwave module and the 2.4G wireless communication module 10 are high-frequency radio frequency devices that emit or receive high-frequency electromagnetic waves during operation. These high-frequency signals can easily cause electromagnetic interference (EMI) to other functional modules, such as causing the main controller 40 to mistrigger or misjudge, resulting in the lamp turning on automatically. Alternatively, when the user adjusts the brightness via touch buttons, electromagnetic interference can cause unresponsiveness, abrupt changes, or incorrect recognition.

[0050] Therefore, in this embodiment, the communication module 10, microwave module 20, and touch sensing module 30 are respectively located on at least two sides of the main controller 40. For example, the main controller 40 is located in the center of the circuit board; the communication module 10 is arranged on one side of the main controller 40 (e.g., the left side) for easy antenna wiring; the microwave module 20 is arranged on the other side of the main controller 40 (e.g., the right side), away from the communication module 10, to reduce high-frequency signal interference; the touch sensing module 30 is arranged on the top or bottom of the main controller 40 for easy connection of leads to the touch area of ​​the lamp housing. Furthermore, shielded wiring or ground plane isolation can be used between the functional modules to further reduce electromagnetic interference between modules. In this embodiment, the distance between the positions of each functional module on the circuit board needs to be greater than or equal to a preset first distance, such as 20mm, to avoid mutual interference.

[0051] In practical applications, smart lighting fixtures include various detection methods, enabling multi-lamp collaborative control in smart home scenarios. By distributing the functional modules of smart lighting fixtures on the circuit board, mutual interference between them is reduced from a physical layout perspective, improving the anti-interference performance of each functional module, thereby enhancing the stability and reliability of smart lighting fixtures and improving the user experience.

[0052] In one embodiment, reference Figure 1 The touch sensing module 30 is located on one side of the main controller 40, as shown on the left, while the microwave module 20 and the communication module 10 are located on the other side of the main controller 40, as shown on the right. The communication module 10 (e.g., a 2.4G wireless module) and the microwave module 20 (e.g., a 5.8G microwave sensing module) are high-frequency radio frequency modules, which generate strong electromagnetic interference during operation. The touch sensing module 30 is extremely sensitive to electromagnetic interference, easily leading to false triggering. Therefore, the touch sensing module 30 and the radio frequency module are respectively arranged on opposite sides of the main controller 40 to achieve physical isolation and reduce interference.

[0053] In one embodiment, the communication module 10, the microwave module 20, and the touch sensing module 30 are disposed around the main controller 40, and the communication module 10, the microwave module 20, and the touch sensing module 30 are disposed on different sides of the main controller 40.

[0054] refer to Figure 2The touch sensing module 30 is located on the left side of the main controller 40, the communication module 10 is located on the right side of the main controller 40, and the microwave module 20 is located below the main controller 40. Thus, the functional modules are located on different sides of the main controller 40. Modules prone to electromagnetic interference, such as the microwave module 20 and the communication module 10, are separated from the touch module, which is susceptible to electromagnetic interference, by being located on different sides of the main controller 40. This physical isolation effectively reduces EMI interference. It improves the slow response time when users perform touch operations via touch buttons due to electromagnetic interference and reduces the risk of accidental activation or deactivation due to electromagnetic interference, thereby enhancing the user experience.

[0055] In another embodiment, the main controller 40 includes a microwave signal pin, a linkage signal pin, and a touch signal pin, wherein the distance between any two of the microwave signal pin, the linkage signal pin, and the touch signal pin is greater than a preset safety distance.

[0056] refer to Figure 3 U1 is the main controller 40. The microwave signal pin WB uses pin 16, the linkage signal pin DATA uses pin 9, and the touch signal pin KEY uses pin 5 on the other side. This arrangement, with the microwave signal pin WB and linkage signal pin on different sides from the touch signal pin, reduces interference from microwave and linkage signals on the touch control signal received by the touch signal pin. Furthermore, the interface distance between the linkage signal pin DATA and the microwave signal pin WB is greater than a preset safety distance, providing a larger safety margin to reduce interference between human movement electrical signals and linkage signals. This pin configuration of the main controller 40 chip reduces misjudgments and false triggers caused by signal interference, improving the stability and reliability of the smart lighting fixture and ultimately enhancing the user experience.

[0057] In one embodiment, the main controller 40 is further configured to control the lamp body to work when it receives a touch control signal or a human body movement electrical signal, and send a linkage signal to the communication module 10 so that an external device can receive the linkage signal.

[0058] In accordance with the above embodiments, when the main controller 40 receives a touch control signal output by the touch sensing module 30 or a human movement electrical signal output by the microwave module 20, it controls the lamp body to operate. That is, if the touch control signal or the human movement electrical signal corresponds to an on command, the main controller 40 controls the lamp to turn on and simultaneously sends a linkage signal to other smart lamps (associated smart lamps) that are communicating with this lamp. When other smart lamps receive the linkage signal, they can further determine whether they need to control themselves to turn on based on the touch control signal or the human movement electrical signal, in order to save energy.

[0059] In this embodiment, the main controller 40 is also used to control the lamp body to work when it receives a linkage signal output by an external device via the communication module 10. Correspondingly, when the main controller 40 of other smart lamps receives a linkage signal, it will immediately control the lamp body to work, so as to realize that multiple associated smart lamps light up synchronously.

[0060] Taking a fire alarm-linked emergency lighting system composed of multiple intelligent lighting fixtures as an example, this system includes multiple intelligent lighting fixtures, a fire alarm system (such as smoke detectors, heat detectors, fire alarm control panels, buzzer modules, etc.), and communication circuits. Multiple intelligent emergency lighting fixtures can be installed in key areas such as teaching buildings, dormitories, laboratories, libraries, corridors, and stairwells, and linked with the fire alarm system. When a smoke detector detects smoke, a heat detector detects abnormal high temperatures, or a manual alarm button is pressed, the fire alarm control panel sends a linkage signal to the main controller 40 of each intelligent lighting fixture, simultaneously controlling the buzzer module to sound an alarm. Upon receiving the linkage signal, each main controller 40 immediately controls the lighting fixture to operate in fire emergency mode, such as switching to high brightness or white light mode, so that it can still provide lighting if the main power supply is interrupted due to a fire; or it can activate a flashing or blinking mode to attract attention.

[0061] It should be noted that because multiple smart lights are connected via communication module 10, they will quickly and synchronously respond upon receiving a linkage signal. This prevents confusion in the dark when the main power fails, ensuring all emergency lights illuminate simultaneously, clearly indicating escape routes, and maximizing evacuation speed. This improves user safety. Furthermore, triggering without manual intervention further enhances safety and efficiency.

[0062] Taking a synchronous lighting system for a classroom composed of multiple smart lamps as an example, this system includes smart lamps (multiple deployed in the same classroom), communication circuits, control devices, an academic affairs system or examination management system, and remote control terminals (such as a teacher's app or management platform). For example, 6-10 smart lamps are deployed in each classroom, adjusted according to the area and lighting requirements. When the exam starts, the teacher sends an "exam mode" command via the app or control panel, or the academic affairs system automatically pushes the exam schedule. Based on the "exam mode" command or exam schedule, the control device determines that the exam lighting mode is required. When the lights need to be turned on, a linkage signal is sent to the communication module 10 of each smart lamp via the communication circuit. In this way, all lamps are controlled to turn on simultaneously; for example, set to high brightness, natural light with a color temperature of around 5000K. This avoids local dark areas affecting students' answers and allows remote control of the lights in multiple classrooms, suitable for large-scale exam scenarios. In addition, when the exam lighting mode is triggered, automatic sensors (such as microwave / touch modules) can be turned off to prevent them from turning off midway; a timer can also be set to turn off automatically (such as automatically turning off the lights at the end of the exam).

[0063] Multiple lights can be wirelessly linked via communication module 10, resulting in a short response time and synchronized activation, thus improving response speed. Linked control avoids unnecessary repetitive operations, reduces energy consumption, and improves management efficiency. It provides timely, uniform, and bright lighting in special scenarios such as emergencies or examinations, ensuring personnel safety and a positive user experience.

[0064] It should be noted that when the lighting fixture sends a linkage signal, the electromagnetic interference generated by the communication module 10 (such as a 2.4G wireless module) can affect the normal operation of the microwave module 20 (such as a 5.8G radar module), causing the smart lighting fixture to enter a false triggering loop, resulting in the lighting fixture remaining on and unable to be turned off. For example, when the lighting fixture sends a linkage signal to other smart lighting fixtures through the communication module 10 (such as a 2.4G wireless module), the radio frequency signal emitted by this module will cause electromagnetic interference (EMI) to the microwave module 20 (such as a 5.8G radar module). This interference may cause the microwave module 20 to mistakenly determine that someone is moving and within its detection range, and output a false human movement electrical signal to the main controller 40. After receiving the human movement electrical signal, the main controller 40: controls the lighting fixture to turn on, and sends the linkage signal again through the communication module 10. The linkage signal interferes with the microwave module 20 again, and the microwave module 20 misjudges again; thus, it enters a loop, causing the lighting fixture to remain on and unable to be turned off normally.

[0065] Optionally, the main controller 40 is further configured to stop receiving the touch control signal and the human body movement electrical signal within a preset time period when sending the linkage signal to the communication module 10.

[0066] The preset duration is set in advance by the R&D personnel.

[0067] In this embodiment, after the main controller 40 sends a linkage signal through the communication module 10, it can first shield the human body movement electrical signal and touch control signal for a period of time (e.g., 2 seconds) to prevent the sending of the linkage signal from interfering with the normal operation of the microwave module 20 or the touch sensing module 30, thereby causing false triggering or misjudgment.

[0068] refer to Figure 4 U2 is the touch sensing module 30, which determines whether a touch button has been pressed by observing the charging and discharging rate of capacitor C1 connected to pin 4. Understandably, when the touch button is pressed, the charging and discharging rate of capacitor C1 changes; when the user is not operating the touch button, the charging and discharging rate of capacitor C1 remains essentially unchanged, tending towards a stable state. (Reference) Figure 5 J2 is microwave module 20. (Reference) Figure 6 U3 is a 2.4G wireless communication module 10. The parameters of the high-frequency inductors L1 and L2 are set in advance by the R&D personnel according to actual needs.

[0069] In this embodiment, the main controller 40 sends a linkage signal via the communication module 10, which can execute a shielding mechanism. This can be achieved by setting a "shielding flag," which is set to 1 after sending the linkage signal; starting a timer and clearing the shielding flag after 2 seconds; during the shielding period, the main controller 40 ignores signals from the microwave module 20 or the touch sensing module 30; after the shielding ends, it continues to scan the states of U2 and J2. Furthermore, if a new touch or human movement signal is received during the shielding period, a buffering mechanism can be set: the signal is temporarily stored in a buffer; after the shielding ends, the buffered signal is processed. This reduces the inconvenience caused by the risk of signal loss without affecting the anti-interference effect.

[0070] Optionally, the touch sensing module 30 detects human touch signals at a first preset frequency, the main controller 40 receives the linkage signal via the communication module 10 at a second preset frequency, and the microwave module 20 receives the reflected microwave signal at a third preset frequency.

[0071] The first preset frequency is greater than the second preset frequency; the second preset frequency is greater than the third preset frequency.

[0072] In this embodiment, the first, second, and third preset frequencies are pre-set by the R&D personnel. Taking a first preset frequency of 100Hz (triggered every 10 milliseconds), a second preset frequency of 5Hz (triggered every 200 milliseconds), and a third preset frequency of 2Hz (triggered every 500 milliseconds) as an example, the touch sensing module 30 scans for human touch signals at a frequency of f1 = 10Hz, the communication module 10 receives linkage signals at f2 = 5Hz, and checks every 200ms for linkage signals from other lamps or external devices. The microwave module 20 receives reflected microwave signals at f3 = 2Hz. Thus, the main controller 40 rationally allocates resources based on the signal frequency differences of each module; upon receiving any valid signal (touch, linkage, human movement), it controls the lamp to turn on; the different scanning (detection) times at different frequencies reduce signal interference between modules.

[0073] High-frequency tasks (touch detection) are prioritized to ensure immediate response to user actions. Mid-frequency tasks (communication monitoring) receive secondary priority to ensure timely reception of linkage signals; low-frequency tasks (microwave detection) are processed later to avoid impacting the main workflow and reduce system load. This reduces signal interference between modules. The scanning mechanism at different frequencies, combined with the shielding mechanism, enhances anti-interference capabilities and stability. Furthermore, through a combination of hardware and software, multiple smart lights and multifunctional modules can work collaboratively while improving anti-interference performance, reducing interference between different signals, lowering production defect rates, and minimizing resource waste.

[0074] This invention proposes a multi-lamp intelligent system, including any of the intelligent lamps described above, wherein the number of intelligent lamps is multiple;

[0075] The intelligent lamp is used to control the working state of its own lamp body according to the human body movement electrical signal output by its own microwave module 20 and the touch control signal output by the touch sensing module 30 when it receives the linkage signal.

[0076] Optionally, the intelligent lighting fixture is used to control its own lighting body to be in working state when it receives a linkage signal.

[0077] The multi-lighting intelligent system includes, but is not limited to, the fire alarm-linked emergency lighting system and the synchronous lighting system for classrooms described in the above embodiments. Further details will not be elaborated upon here.
