The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this disclosure. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0035] Please see Figures 1 to 3 This is an embodiment of the microwave radar sensing-based lamp panel 10, comprising a housing 100, a light source control component 200, and a light-transmitting plate 300. The light source control component 200 includes a power driver 210, a lamp panel 220, and a radar sensor controller 230. The housing 100 has a mounting groove 101. The lamp panel 220 is located in the mounting groove 101 and disposed in the housing 100. The power driver 210 is disposed on the outside of the housing 100. The power output terminal of the power driver 210 is electrically connected to the lamp panel 220. The light-transmitting plate 300 is connected to the housing 100, and the opening of the mounting groove 101 faces the light-transmitting plate 300. The radar communication terminal of the power driver 210 is electrically connected to the transceiver terminal of the radar sensor controller 230. The radar sensor controller 230 is located in the mounting groove 101 and connected to the housing 100, and the sensing terminal of the radar sensor controller 230 faces the light-transmitting plate 300.

[0036] like Figures 5 to 7 As shown, the radar sensor controller 230 has a microwave radar communication circuit 2300, which includes a communication circuit 2301, a voltage regulator 2302, and a radar sensing circuit 2303. The communication circuit 2301 includes a communication chip 230a and a signal filtering circuit 230b. One communication terminal of the signal filtering circuit 230b is connected to the bidirectional communication terminal of the communication chip 230a. The third terminal of the voltage regulator 2302 is connected to the second communication terminal of the signal filtering circuit 230b, and the first terminal of the voltage regulator 2302 is connected to signal ground. The radar sensing circuit 2303 includes a radar RF chip U3 and a radar control unit U5. The reference voltage terminal of the radar RF chip U3 is connected to the second terminal of the voltage regulator 2302. The signal acquisition terminal of the radar control unit U5 is connected to the signal receiving terminal of the radar RF chip U3. The sensing terminal OUT1 of the radar control unit U5 is used to acquire the movement signal of a moving object, corresponding to pin 16 of the radar control unit U5. Furthermore, the two communication terminals of the signal filtering circuit 230b are connected to the third terminal of the voltage regulator 2302 via a 5V voltage; the second terminal of the voltage regulator 2302 is connected to the radar RF chip U3 via a 3.3V voltage.

[0037] It can be understood that the communication interaction one end and the communication interaction two end of the signal filtering circuit 230b are represented as the signal filtering circuit 230b having two ends, one end being electrically connected to the communication chip 230a and the other end being connected to the voltage regulator 2302, so that the communication chip 230a and the radar RF chip U3 can achieve bidirectional communication through signal filtering and voltage conversion.

[0038] In this design, the sensing terminal OUT1 of the radar control unit U5 serves as a radar antenna, used to sense stationary or moving human bodies or objects. When a moving object is detected, its movement signal is high-level, and the radar sensor controller 230 outputs a high-level signal, enabling the lamps to illuminate normally. When no moving object is detected, its movement signal is low-level, and the radar sensor controller 230 outputs a low-level signal, keeping the lamps in a low-brightness state. The schematic diagram is shown below. Figure 8 As shown.

[0039] In this embodiment, the radar antenna is located at the sensing end of the radar control unit U5 to optimize the antenna layout and circuit design. In addition, the sensing end of the radar sensor controller 230 faces the light-transmitting plate 300, which can improve the sensing distance and sensitivity. Furthermore, an anti-interference circuit design is adopted, such as the signal filtering circuit 230b, to enhance the module's anti-interference ability against other electromagnetic signals in the environment. It can also ensure communication stability in complex electromagnetic environments, that is, to ensure communication between the communication chip 230a and the radar RF chip U3, as well as communication with other modules in the same frequency band, thereby improving compatibility with the equipment and achieving efficient and stable communication.

[0040] Furthermore, the communication chip 230a adopts a 2.4GHz Mesh chip, which can realize distributed control of the lighting fixtures when applied to them. Thus, users can control the lighting fixtures or remotely upgrade the radar module through APP, mini-program, etc. Furthermore, the radar sensor controller 230 communicates with the user terminal or other modules in the same frequency band using 2.4GHz. The radar RF chip U3 adopts an X-band RF chip, which operates in the microwave band with a short wavelength (about 2.5-3.75cm), suitable for high-precision detection and high-speed data transmission. The radar sensor controller 230 applied in this solution can accurately detect stationary or slowly moving human bodies.

[0041] like Figure 5 and Figure 6 As shown, in one embodiment, the signal filtering circuit 230b includes a first capacitor C1, a second capacitor C6, a first inductor L2, and a second inductor L3. The upper half of the first capacitor C1 is connected to one communication terminal of the communication chip 230a, corresponding to pin 28 of the communication chip 230a. The lower half of the first capacitor C1 is grounded. The upper half of the second capacitor C6 is connected to the second communication terminal of the communication chip 230a, corresponding to pin 27 of the communication chip 230a. The lower half of the second capacitor C6 is connected to the first terminal of the first inductor L2. The second terminal of the first inductor L2 is connected to the first terminal of the second inductor L3 and the third terminal of the voltage regulator 2302, respectively. The second terminal of the second inductor L3 is grounded. It is understandable that multiple capacitors and multiple inductors can be combined to form an inductor-capacitor (LC) resonant circuit, which is used for frequency selection filtering to ensure that the communication chip 230a can efficiently transmit and receive signals within a specific frequency band, suppress interference from other frequency bands, and improve the reliability and anti-interference capability of communication. In this way, the communication stability between the radar module and the lighting module can be maintained in a complex electromagnetic environment, while also suppressing signal noise. This achieves dual filtering, ensuring the bidirectional communication performance between the communication chip 230a and the radar RF chip U3, and preventing the unstable signal acquired by the radar module caused by interference from other signals.

[0042] like Figure 6 As shown, in one embodiment, the signal filtering circuit 230b further includes a third capacitor C8. The upper half of the third capacitor C8 is connected to the lower half of the first capacitor C1, and the lower half of the third capacitor C8 is connected to the first end of the second inductor L3, so as to filter the interference signal when passing through the 5V voltage terminal and ensure the communication performance between the two chips.

[0043] like Figure 5 and Figure 6As shown, in one embodiment, the communication circuit 2301 further includes a crystal oscillator 230c. The first terminal of the crystal oscillator 230c is connected to the clock input terminal of the communication chip 230a, and the third terminal of the crystal oscillator 230c is connected to the clock output terminal of the communication chip 230a. The second and fourth terminals of the crystal oscillator 230c are both grounded. It can be understood that the clock input terminal Xin and the clock output terminal Xout of the communication chip 230a are both connected to the crystal oscillator 230c to form an oscillation circuit. The crystal oscillator 230c is used to provide a system clock reference to prevent packet loss during communication. Thus, when the user controls the lights through an app or mini-program, or when the radar module is upgraded via OTA, the communication chip 230a can receive data packets requested by the user.

[0044] like Figure 6 As shown, in one embodiment, the microwave radar communication circuit 2300 further includes a fourth capacitor C13 and a fifth capacitor C16. The upper half of the fourth capacitor C13 is connected to the first terminal of the crystal oscillator 230c, and the lower half of the fourth capacitor C13 is grounded. The upper half of the fifth capacitor C16 is connected to the third terminal of the crystal oscillator 230c, and the lower half of the fifth capacitor C16 is grounded. By setting the fourth capacitor C13 and the fifth capacitor C16, a passive crystal connection is formed. The lower half of both the fourth capacitor C13 and the fifth capacitor C16 is grounded, which can filter out high-frequency noise. The fourth capacitor C13 and the fifth capacitor C16 are also used to fine-tune and compensate for crystal manufacturing tolerances or temperature drift, so that the oscillation frequency accurately matches the target value, further ensuring that the communication chip 230a can normally receive data packets requested by the user.

[0045] like Figure 5 and Figure 7 As shown, in one embodiment, the microwave radar communication circuit 2300 further includes a sixth capacitor C18 and a seventh capacitor C20. The upper half of the sixth capacitor C18 is connected to the third terminal of the voltage regulator 2302, and the lower half of the sixth capacitor C18 is grounded. The upper half of the seventh capacitor C20 is connected to the second terminal of the voltage regulator 2302, and the lower half of the seventh capacitor C20 is grounded. The sixth capacitor C18 is used to filter out interference signals passing through the third terminal of the voltage regulator 2302, and the seventh capacitor C20 is used to filter out interference signals passing through the first terminal of the voltage regulator 2302, preventing damage to components caused by sudden voltage changes at each terminal of the voltage regulator 2302.

[0046] like Figure 5 and Figure 7As shown, in one embodiment, the microwave radar communication circuit 2300 further includes an eighth capacitor C26. The upper half of the eighth capacitor C26 is connected to the analog-to-digital converter receiving terminal of the radar RF chip U3 and the analog-to-digital converter terminal of the radar control unit U5, respectively, and the lower half of the eighth capacitor C26 is connected to signal ground. It can be understood that when the radar control unit U5 acquires the data corresponding to the movement state, it transmits the signal data to the radar RF chip U3 through analog-to-digital conversion. During this process, the eighth capacitor C26 is used to filter out interference signals acquired by the radar control unit U5 to ensure the stability of the signal data received by the radar RF chip U3.

[0047] like Figure 3 and Figure 4 As shown, in one embodiment, the radar sensor controller 230 includes a radar pre-installed housing 231 and a radar sensing circuit board 232. A microwave radar communication circuit 2300 is disposed inside the radar sensing circuit board 232. The radar pre-installed housing 231 is disposed inside the housing 100. The radar sensing circuit board 232 is located in the mounting slot 101 and connected to the housing 100. The radar sensing circuit board 232 is electrically connected to the radar communication terminal of the power driver 210. The sensing terminal of the radar sensing circuit board 232 is disposed facing the light-transmitting plate 300 so that the sensing part of the radar sensing circuit board 232 can collect the movement of objects below the lamp and control the lamp to illuminate normally or enter a low brightness state according to the above situation.

[0048] like Figure 3 and Figure 4 As shown, in one embodiment, the radar sensor controller 230 further includes a heat-conducting component 233. The radar sensing circuit board 232 is disposed inside the radar pre-mounted housing 231 via the heat-conducting component 233, so that the heat generated by the radar sensing circuit board 232 during operation is transferred to the radar pre-mounted housing 231, thereby achieving uniform heat dissipation and preventing damage to local components due to excessively high temperatures. Furthermore, the heat-conducting component 233 can be silicone grease, silicone gel, etc.

[0049] This disclosure also provides a lighting system including a microwave radar sensing-based lamp panel 10 of any of the above embodiments.

[0050] Compared with the prior art, this disclosure has at least the following advantages:

[0051] Because the radar antenna is located at the sensing end of the radar control unit U5, the antenna layout and circuit design are optimized. In addition, the sensing end of the radar sensor controller 230 faces the light-transmitting plate 300, which can improve the sensing distance and sensitivity. Furthermore, an anti-interference circuit design is adopted, such as the signal filtering circuit 230b, to enhance the module's anti-interference ability against other electromagnetic signals in the environment. It can also ensure communication stability in complex electromagnetic environments, that is, to ensure communication between the communication chip 230a and the radar RF chip U3, as well as communication with other modules in the same frequency band, thereby improving compatibility with the equipment and achieving efficient and stable communication.

[0052] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
