[0019] See the attached figures. The voice-controlled desk lamp controller described in this embodiment includes an offline voice module, an MCU control circuit, multiple DC / DC dimming and step-down circuits, a DC / DC step-down power supply circuit, a lighting module, a power amplifier IC, a microphone input interface, and a speaker output interface.

[0020] The DC / DC step-down power supply circuit is electrically connected to the offline voice module, MCU control circuit, multiple DC / DC dimming step-down circuits, and power amplifier IC to provide them with operating voltage. The input terminal of the DC / DC step-down power supply circuit is connected to 48V voltage, and the output terminal outputs 5V voltage, providing a stable operating voltage for each module in the entire system and ensuring the normal operation of each module.

[0021] The MCU control circuit uses the CA51F152P6A chip, which has rich interfaces and functions, enabling touch control. It can also receive and process signals from the offline voice module and send control signals to various DC / DC dimming step-down circuits.

[0022] Multiple DC / DC dimming step-down circuits include a first DC / DC dimming step-down circuit, a second DC / DC dimming step-down circuit, and a third DC / DC dimming step-down circuit, all of which are connected to a 48V voltage. These dimming step-down circuits can convert the 48V high voltage into a voltage suitable for the operation of the lighting module and realize the dimming function of the light.

[0023] The first DC / DC dimming step-down circuit is connected to a PWM-H signal, the second DC / DC dimming step-down circuit is connected to a PWM-L signal, and the third DC / DC dimming step-down circuit is connected to a PWM-R signal. These PWM signals can precisely control the output of the corresponding dimming step-down circuits, thereby achieving brightness adjustment of different parts of the lighting module.

[0024] The first DC / DC dimming step-down circuit uses the BP1386 control chip to adjust the brightness of the main lighting area. The BP1386 is a commonly used LED step-down constant current driver chip, supporting wide voltage input and PWM dimming, and possessing high output current stability, making it suitable for driving high-power, high-brightness main lighting modules. As the core lighting area of ​​the desk lamp (covering the main study area of ​​the desktop), the main lighting area requires stable and sufficient light. The constant current characteristics of the BP1386 ensure uniform brightness and flicker-free operation in the main lighting area, meeting the eye-protection needs for long-term study.

[0025] The second DC / DC dimming and buck circuit uses the BP1386 control chip to adjust the brightness of the left auxiliary lighting area. This second DC / DC dimming and buck circuit connects to a "PWM-L" signal. The BP1386 supports independent PWM dimming, allowing for precise adjustment of the brightness of the left auxiliary lighting area to suit left-handed users or the supplementary lighting needs of left-handed objects (such as reference books or stationery). Sharing the BP1386 chip with the first DC / DC dimming and buck circuit ensures consistency in dimming response speed and stability between the auxiliary and main lighting, preventing excessive differences in light intensity between the left and right sides.

[0026] The third DC / DC dimming step-down circuit uses the BP1808 control chip to adjust the brightness of the right-side auxiliary lighting area. This circuit connects to a "PWM-R" signal, and the BP1808 also supports PWM dimming. This is used to match the specific needs of the right-side auxiliary lighting area, adapt to supplemental lighting for objects on the right, and improve the overall balance of the desktop lighting.

[0027] When a user issues a voice command, the microphone input interface receives the voice signal and transmits it to the offline voice module. The offline voice module processes the voice signal and converts it into a corresponding electrical signal. The offline voice module communicates with the MCU control circuit through interfaces such as TX0 and RX0, sending control signals to the MCU control circuit.

[0028] The MCU control circuit uses the CA51F152P6A chip to receive control signals from the offline voice module, and can also receive user key operation signals. After processing these signals, the MCU control circuit sends the control signals to the first DC / DC dimming step-down circuit, the second DC / DC dimming step-down circuit, and the third DC / DC dimming step-down circuit.

[0029] The first, second, and third DC / DC dimming step-down circuits, upon receiving control signals from the MCU control circuit, regulate and convert the voltage to power the lighting module, thereby enabling the switching and brightness adjustment of the lighting module. Specifically, the first DC / DC dimming step-down circuit adjusts according to the PWM-H signal, the second DC / DC dimming step-down circuit adjusts according to the PWM-L signal, and the third DC / DC dimming step-down circuit adjusts according to the PWM-R signal.

[0030] Meanwhile, the offline voice module connects to the power amplifier IC, transmitting the voice signal that needs feedback to the power amplifier IC. After amplifying the signal, the power amplifier IC outputs voice feedback through the speaker output interface, allowing the user to know the operation result.

[0031] In addition, the KEY3-KEY8 key interfaces on the MCU control circuit can receive key operation signals. When the user touches the corresponding key, a corresponding electrical signal is generated. These signals are transmitted to the MCU control circuit. After the MCU control circuit recognizes and processes them, it issues corresponding control commands to control the lighting, thereby improving the flexibility of operation.

[0032] There are no specific restrictions on the models of the offline voice module and power amplifier IC, as long as they can achieve the above functions. For example, commonly used offline voice module models include NRK330X, NRK3502, VC-02, etc., and commonly used power amplifier IC models include LM386, TDA2822, etc.

[0033] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
