Technical Field

[0001] This invention relates to the field of lighting fixtures, specifically a multifunctional voice-controlled household appliance lighting fixture. Background Technology

[0002] LED lights have the advantages of energy saving and environmental protection, and have become a major trend in the lighting industry. White LEDs consume only 1 / 10 the energy of incandescent lamps and 1 / 4 the energy of energy-saving lamps; their lifespan can reach over 100,000 hours, making them a truly "one-and-done" solution for ordinary household lighting. However, existing lighting fixtures still have the following technical problems in use: Existing lighting fixtures have limited functionality, serving only the purpose of illumination. As living environments become increasingly intelligent, current lighting fixtures are unable to easily control various household appliances and other daily necessities, making them insufficiently intelligent in use.

[0003] Therefore, a multifunctional voice-controlled home appliance lighting fixture is proposed to solve the aforementioned problems. Summary of the Invention

It is the foundation of all voice control functions. Local speech processing module 7 is responsible for voice wake-up, local offline speech recognition, and semantic parsing; The main control module 8 is used to receive the parsing instructions from the voice processing module, distribute execution signals to the lamp driving module or the home appliance control execution module, receive feedback signals from each module, and realize the process closed loop. The lamp body drive execution module 9 receives instructions from the main control module to precisely control the lamp's on / off state, stepless brightness adjustment, and light color switching.

The A / D conversion chip converts analog audio signals into digital signals for subsequent voice processing modules to recognize and analyze.

[0023] The local voice processing module 7 includes a voice processing chip with a built-in custom wake-up word (such as "little light, little light") to achieve low-power wake-up. The microphone picks up sound during standby, and full-function recognition only starts after the wake-up word is triggered, saving power. It also includes built-in core commands and a universal code library for light control and home appliance control (such as "turn on / off light", "brighten to 80%", "switch to warm / cool light", "turn on air conditioner, turn off air conditioner, cooling mode, heating mode...16 degrees,...26 degrees,...32 degrees, etc.", "turn on projector"). It can quickly recognize commands without a network connection, with a response latency of less than 1 second. It determines whether the command belongs to the light itself (on / off / brightness / color of light) or to an external home appliance (air conditioner / TV / projector / robot vacuum cleaner) and generates standardized execution commands.

[0024] The main control module 8 is a high-performance microcontroller (MCU, such as STM32, ESP32 series).

[0025] The lamp body drive execution module 9 includes a switch drive circuit (relay, thyristor), a PWM dimming chip, an RGB / WRGB lamp bead drive circuit, and a current / voltage sampling circuit; The switch driver circuit controls the on / off state of the lamp, and the PWM dimming chip adjusts the pulse width to achieve stepless brightness adjustment (0-100%), adapting to different brightness requirements. In the RGB / WRGB LED driver circuit, if it is a full-color lamp, the current of the four LEDs (R (red), G (green), B (blue), and W (white)) is controlled to achieve precise color adjustment (3000K-6500K for warm and cool light, full color gamut); if it is a single-color temperature dimming, only the warm and cool white LEDs need to be driven.

[0027] The WIFI / Bluetooth communication module 11 is a WiFi 2.4G module, such as ESP8266 / ESP32, which is compatible with home WiFi and enables the connection between the light fixture and the home router. Its functions are as follows: remote control of the light fixture via mobile APP, supplementing voice control; online upgrade of voice command library and infrared code library (no need to disassemble the device, new brand home appliance codes and new voice commands are pushed to the cloud); transparent transmission of WiFi commands to control home WiFi smart home appliances.

The stored content includes voice wake-up words, local voice command library, universal infrared code library, lamp working parameters (default brightness / color), and user-defined settings, such as commonly used home appliance commands and wake-up words, enabling offline operation.

[0029] The power supply and power management module 13 includes an AC-DC power conversion circuit, a voltage regulator circuit, an overvoltage / overcurrent / short circuit protection circuit, and a low-power standby circuit.

[0030] The auxiliary human-machine interaction module 14 includes a status indicator light, a touch button, and a buzzer. The status indicator light displays the working status of the lamp (standby / wake-up / network configuration / fault) and the WiFi connection status. The touch button enables manual network configuration, voice wake-up word reset, infrared code learning, and factory reset, solving emergency operations when voice control fails. The buzzer emits a prompt tone when voice wake-up is successful, command execution is completed, or network configuration is successful, providing auditory feedback.

[0031] The complete workflow of each module working together, taking voice-activated air conditioning and light color adjustment as an example; 1. The user gives the voice command: "Little light, little light, turn on the air conditioner to 26 degrees, switch to warm light." 2. The microphone array of the sound acquisition module picks up commands, reduces noise, converts them into digital signals, and transmits them to the voice processing module; 3. The voice processing module recognizes the wake word "xiaodengxiaodeng" and triggers full-function recognition, parsing out two commands: home appliance control command (air conditioner 26 degrees) and lamp control command (switch to warm light); 4. The main control module receives and parses the instructions, and then distributes execution signals to the infrared emitting module and the lamp body driving execution module respectively; 5. The execution layer works simultaneously: The infrared transmitting module calls the infrared code of the corresponding air conditioner such as Gree / Midea and transmits a 26-degree start command to start the air conditioner; the lamp driving module adjusts the RGB / WRGB lamp beads and switches to warm light (3000K). 6. The buzzer emits a "beep" sound to indicate that the instruction has been executed and the process is complete.
