[0019] (6) Interaction module, the components of which are described in detail below: Physical touch buttons: Capacitive touch buttons are embedded in the side groove of the metal frame, with the surface flush with the frame.

[0020] like Figure 1As shown, in this embodiment, the metal frame 1 adopts a circular design with an outer diameter of 600mm and a thickness of 40mm, and is made of 6063 aluminum alloy; the crystal pendant 2 is made of K9-cut crystal, distributed in 3 layers, with 10 pieces in each layer, and is fixed by metal buckles and silicone anti-slip pads; the LED lamp bead array 3 consists of 40 LED lamp beads (20 cold light beads + 20 warm light beads), which are installed in a ring on the inner side of the metal frame; the light-transmitting cover 4 is made of frosted acrylic material, with a diameter of 580mm and a thickness of 4mm; the control box 5 is embedded in the top of the frame, with dimensions of 100mm×100mm×50mm, and is installed flush with the ceiling, and has a built-in intelligent control module, power supply and safety module; the physical touch buttons 6 are embedded in the grooves on the side of the frame, with a total of 4 buttons and a spacing of 20mm; the sensor detection holes 7 are opened below the control box, with a diameter of 5mm, and a quantity of 2 (corresponding to the human infrared sensor and the light sensor respectively); the power cord interface 8 is located on the side of the control box and uses a waterproof connector.

[0021] like Figure 2 As shown, the control system is based on the ESP32 main control chip 21. The human infrared sensor 11 and light sensor 12 in the perception layer transmit the detection signals to the main control chip in real time. The physical touch button 41, mobile APP 42, and intelligent voice assistant 43 in the interaction layer send control commands. After receiving the signal, the main control chip judges the circuit status through the fault detection unit 23. If the status is normal, the command reception status is fed back through the Wi-Fi / Bluetooth communication module 22, and the LED driver module 31 is driven to control the LED beads 32 to work. If an abnormality is detected, the safety protection module 33 is immediately triggered to cut off the power supply, and a fault prompt is pushed through the mobile APP 42.

[0022] like Figure 3As shown, the power supply section of this invention: AC220V mains power is connected to the isolation power supply U1 (model MEANWELLLRS-25-12) via power line interface 8, converted to DC12V direct current, and after passing through fuse F1 (2A) and protection chip U2 (LM317), it is distributed to the ESP32 main controller U3, LED driver U4 (PT4115), light sensor U5 (BH1750), and human infrared sensor U6 (HC-SR501); the control section: the GPIO18 pin of the ESP32 main controller U3 outputs a PWM signal to control the current of the warm light bead, and the GPIO19 pin outputs a P The WM signal controls the current of the cold light bead to achieve color temperature and brightness adjustment; GPIO21 (SDA) and GPIO22 (SCL) read the brightness data of the light sensor U5 through the I2C interface; the GPIO4 pin receives the trigger signal (active high) of the human infrared sensor U6; GPIO0, GPIO1, GPIO2, and GPIO3 are connected to physical buttons K1 (switch), K2 (mode switch), K3 (brightness +), and K4 (brightness -), respectively; Communication section: the ESP32 main controller U3 has a built-in Wi-Fi antenna ANT1 and a Bluetooth antenna ANT2 to achieve wireless communication with external devices.

[0023] The mobile app interface features a minimalist design. The top displays the device status (showing "Online / Offline") and a main power button (red for off, green for on). The middle section has two adjustment sliders, corresponding to brightness (0-100%) and color temperature (2700K-6500K), with the current value displayed to the right of each slider. The bottom section is the scene mode area, with five buttons: "Reading," "Sleep," "Party," "Movie," and "Energy Saving." The buttons are colored blue, warm yellow, purple, dark gray, and green, respectively, allowing users to switch to the corresponding scene with a single click. The bottom of the interface contains a function entry bar, including four options: "Timer Settings," "Sensitivity Adjustment," "Fault View," and "Custom Scene." Clicking these options leads to the corresponding function page.

[0024] In this embodiment, the total power of the LED array is 15W, the brightness adjustment range is 0-100%, the color temperature adjustment range is 2700K-6500K, the sensing distance is 3-5m (adjustable via APP), the standby power consumption is ≤0.3W, the control delay is ≤1s, and the fault response time is ≤0.5s, fully meeting the needs of home smart lighting. The working principle of this design is explained in detail below: (1) Standby state: The power supply module is working normally, the intelligent control module is in low power mode (power consumption ≤ 0.3W), the sensing module detects the ambient brightness and human activity status in real time, and the interaction module is in standby state.

[0025] (2) Sensing control process: The human infrared sensor detects human movement signal and transmits trigger signal to the main control chip; the light sensor collects ambient brightness data at the same time. If the brightness is ≤100 lux, the main control chip determines that "lighting is needed" and sends PWM control signal to LED driver chip; the LED driver chip adjusts the current of cold / warm light beads according to the signal and turns on the LED light source. The default brightness is 50% and the color temperature is 3500K. The infrared human body sensor continuously detects human activity. If no human activity is detected within 3 minutes, the main control chip sends a command to turn off the lights, the LED light source turns off, and the system returns to standby mode.

[0026] (3) Active control process (physical button / APP / voice): Physical button: Touch the "Switch" button to turn the lamp on and off; touch the "Mode Switch" button to cycle through preset scenes; touch the "Brightness + / -" button to adjust the brightness (in 5% increments); Mobile APP: Users send control commands (such as adjusting brightness or setting timers) through the APP. The commands are transmitted to the main control chip via Wi-Fi. After parsing, the main control chip drives the LED light source module to execute and simultaneously feeds back the execution results to the APP for display; Voice control: Users send voice commands through the intelligent voice assistant. The voice assistant converts the commands into digital signals and transmits them to the main control chip via Wi-Fi. The main control chip drives the execution and, after execution, feeds back "Completed" through the voice assistant.

[0027] (4) Fault handling process The main control chip has a built-in fault detection unit that monitors the LED bead operating current, power supply voltage, and module temperature data in real time. When an abnormality is detected (voltage > 13.5V, current > 2A, temperature > 60℃), it immediately sends a signal to the safety protection module to cut off the power supply circuit. At the same time, it pushes fault prompts (such as "over-temperature protection triggered, please check heat dissipation") through the mobile APP to facilitate users in troubleshooting problems.

[0028] Compared with the prior art, the present invention has the following advantages: (1) Perfect integration of decoration and intelligence: The intelligent modules (control box, sensor) are all installed in a concealed manner, which does not destroy the decorative beauty of the crystal lamp. The combination design of metal frame and crystal pendant is suitable for various home styles.

[0029] (2) Diverse control methods: It supports four control methods: physical touch, remote control via mobile APP, intelligent voice, and human body sensing, to meet the usage habits of different users (such as the elderly and children) and is easy to operate.

[0030] (3) Refined lighting effect: High color rendering LED beads are combined with precise dimming technology, and the brightness and color temperature can be continuously adjusted. Five scene modes are preset and support custom storage, which can be adapted to various home scenarios such as reading, sleeping, and parties, and the lighting comfort is high.

[0031] (4) Reliable safety performance: It integrates overvoltage, overcurrent and overtemperature triple protection, and is equipped with anti-fall crystal pendant design, which complies with GB7000.1-2015 "Safety Requirements for Lighting Fixtures" and is safe to use.

[0032] (5) Energy-saving and efficient: LED light source power consumption is only 15W (equivalent to 100W brightness of traditional incandescent lamp), standby power consumption ≤0.3W, service life ≥50,000 hours, energy-saving and environmentally friendly.

[0033] The above description is only a preferred embodiment of the present invention. Therefore, all equivalent changes or modifications made in accordance with the features and principles described in the claims of this patent application are included in the scope of this patent application.
