Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.

[0041] like Figures 1 to 11 As shown, this utility model embodiment provides a control system for a multifunctional reading lamp, including:

[0042] A smart bracelet 70 includes a bracelet body and a first microcontroller, a temperature sensing module 74, a signal transmitting module, and a first power module disposed within the bracelet body. The temperature sensing module 74, the signal transmitting module, and the first power module are all electrically connected to the first microcontroller. The temperature sensing module 74 is used to detect the temperature signal of the user wearing the smart bracelet 70 and transmit the temperature signal to the first microcontroller. The first microcontroller is used to transmit the received temperature signal to a multi-functional reading light through the signal transmitting module. The first power module is used to supply power to the smart bracelet 70.

[0043] A multi-functional reading lamp includes a lamp body, a second microcontroller, a signal receiving module, an LED driving circuit, and an LED light group disposed on the lamp body. The signal receiving module is used to transmit the temperature signal received from the smart bracelet 70 to the second microcontroller. The second microcontroller is used to generate a corresponding light signal according to the received temperature signal and transmit the light signal to the LED driving circuit. The LED driving circuit is used to control the display state of the LED light group according to the received light signal.

[0044] In this embodiment, temperature signals can be detected using a wristband to control the lights. Alternatively, temperature difference detection can be used to control the light display. Since the metabolic rate decreases during sleep, body temperature typically drops by about 0.5-1°C. This control system, based on temperature difference, accurately captures the decreasing trend of body temperature as the user enters sleep. As the user's body temperature gradually decreases, the reading light gradually dims according to a preset temperature difference threshold. For example, when a temperature drop of 0.3°C is detected, the light brightness begins to decrease slowly; when the temperature continues to drop, reaching a difference of 0.5°C, the brightness is further reduced until the temperature difference reaches the set final threshold, at which point the light completely turns off. This dimming method, which adapts to the body temperature changes during sleep, perfectly matches the user's transition from wakefulness to sleep, avoiding disturbance caused by sudden light switching and improving the sleep experience.

[0045] By monitoring body temperature differences, the system automatically adjusts the light until it turns off, avoiding energy waste caused by the reading light remaining on after the user falls asleep. Traditional reading lights may consume electricity all night if the user forgets to turn them off, while this system automatically shuts off the power while the user is asleep, significantly reducing energy consumption. Based on a normal nightly reading light power of 10 watts and an average sleep time of 8 hours, leaving the light on all night would consume 0.08 kWh; however, this system saves that amount of electricity by automatically turning off the light after the user falls asleep. At the same time, frequent switching of lights can damage the lifespan of LED light modules. This system avoids unnecessary switching operations, smoothly controlling light brightness changes based on body temperature differences, reducing the impact of current surges on the LED light modules, thereby effectively extending the lifespan of the LED light modules and reducing the frequency and cost of replacing the light fixtures.

[0046] During sleep, the human body is highly sensitive to changes in the environment, and sudden changes in light can disrupt sleep. This system uses gradual dimming based on body temperature differences to ensure that the light does not flicker abruptly during the user's sleep. For example, movements such as turning over at night may cause brief temperature fluctuations in the smart bracelet, but the system will comprehensively assess the trend of body temperature differences and will not incorrectly adjust the light due to these minor fluctuations. This maintains the stability of the sleep environment, helps users maintain deep sleep, improves sleep quality, and reduces sleep problems caused by light interference, such as night awakenings and vivid dreams.

[0047] More preferably, the smart bracelet 70 further includes a display interaction module electrically connected to the first microcontroller, the display interaction module being used to display the control signals sent by the first microcontroller.

[0048] Users can intuitively see the control signals sent by the first microcontroller on the display interaction module. For example, when the temperature sensing module 74 detects a change in the user's body temperature, the first microcontroller generates a corresponding temperature difference signal, which the display interaction module can clearly present in the form of numbers, charts, etc. Users can know their own temperature changes in real time and how these changes will affect the control of the reading light, such as the current temperature difference corresponding to a 20% reduction in the reading light brightness and a warmer color temperature. This allows users to clearly understand the system's operating status and adjust the relevant settings of the wristband or reading light in advance according to their personal preferences and actual needs, obtaining a lighting experience that better suits their needs.

[0049] The display interaction module in this embodiment provides convenient operation feedback. For example, when a user configures the smart bracelet 70, such as adjusting the temperature detection sensitivity or setting the light change mode of the reading light under different temperature differences, the display interaction module will immediately display information such as whether the setting was successful and the specific parameters currently set. Users can quickly receive operation feedback without additional operation or confirmation from other devices, greatly improving operational efficiency and making the control of the smart bracelet 70 and reading light smoother and easier.

[0050] More preferably, the smart bracelet 70 further includes a heart rate detection module and a motion detection module electrically connected to the first microcontroller, wherein the heart rate detection module is used to detect the user's heart rate signal, and the motion detection module is used to detect the user's motion signal.

[0051] The motion detection module can detect the user's motion signals and determine whether the user is in motion or at rest.

[0052] More preferably, such as Figure 3 and Figure 4As shown, the main body of the smart bracelet includes a display body 71, a first connector 72, and a second connector 73. A display screen 711 is located on the front of the display body 71, and a temperature sensing module 74 is located on the back of the display body 71. An adjustment hole 721 is provided on the first connector 72. One end of the second connector 73 is connected to the display body 71, and the other end of the second connector 73 is provided with a fixing buckle 731, which is used to mate with the adjustment hole 721 for installation. A charging interface 75 is also provided on the main body of the smart bracelet, through which the battery module inside the smart bracelet is charged.

[0053] The temperature sensing module 74 is located on the back of the display body 71. When the wristband is worn on the wrist, it can make close and stable contact with the skin, reducing detection errors caused by shaking or displacement, and ensuring accurate detection of the user's body temperature. The display body 71 provides a certain degree of protection for the temperature sensing module 74, preventing interference from external environmental factors such as wind and direct sunlight, so that the detection results can more accurately reflect the user's actual body temperature.

[0054] The adjustment hole 721 on the first connector 72 cooperates with the fixing buckle 731 of the second connector 73 for installation, allowing for flexible adjustment of the watchband length according to the user's wrist size. This makes the bracelet more comfortable to wear, preventing discomfort from being too tight and affecting detection accuracy and wearing stability from being too loose. This adjustable structure can meet the wearing needs of users of different ages and genders. Whether it is children, teenagers or adults, they can find a suitable wearing size through adjustment, thus expanding the applicability of the product.

[0055] More preferably, the first and second microcontrollers are of model ESP32-C3, and the temperature sensing module 74 is of model DS18B20; both the signal transmitting module and the signal receiving module are Bluetooth communication modules.

[0056] The ESP32-C3 in this embodiment integrates a 32-bit RISC-V processor, possessing high computing performance. It can quickly process data from multiple sensors such as temperature, heart rate, and motion, and can also generate accurate lighting control signals in a timely manner. Simultaneously, it employs a low-power design, effectively reducing the power consumption of the smart bracelet 70 and the multi-functional reading light, extending the device's battery life. For example, in the smart bracelet 70, it can be used for a longer period after a single charge, reducing the inconvenience of frequent charging.

[0057] This microcontroller boasts a rich set of peripheral interfaces, such as SPI, I2C, and UART, facilitating connection and communication with various sensors and modules, including the temperature sensing module 74, display interaction module, heart rate detection module, and motion detection module. This allows for easy system expansion and functional upgrades. For example, new sensors or functional modules can be easily added, enhancing the product's competitiveness. The ESP32-C3 incorporates Bluetooth Low Energy (BLE) functionality, enabling seamless integration with Bluetooth communication modules to achieve stable and efficient wireless communication between the smart bracelet 70 and the multi-functional reading light. Bluetooth communication offers advantages such as low power consumption and strong anti-interference capabilities, ensuring accurate transmission of data such as temperature signals between the two devices.

[0058] The DS18B20 temperature sensor boasts a measurement accuracy of ±0.5℃, precisely detecting changes in the user's body temperature and providing accurate temperature data for the Smart Bracelet 70. Based on this precise data, the multi-functional reading light can more accurately adjust its lighting status, such as brightness and color temperature, according to the user's body temperature, offering a more personalized lighting experience. The DS18B20 uses a single-bus interface, requiring only one data cable to communicate with the microcontroller, greatly simplifying circuit design and reducing hardware costs and board space requirements. This makes the Smart Bracelet 70 more compact, easier to carry and wear. The module exhibits strong anti-interference capabilities and stability, operating normally within a wide temperature range (-55℃ to +125℃), adapting to various usage environments and ensuring accurate measurement of the user's body temperature under all conditions.

[0059] More preferably, the multi-functional reading light includes a touch control button, an audio module, a water level detection sensor, and an ultrasonic atomizer electrically connected to the second microcontroller. The water level detection sensor is disposed in the water tank to detect the water level signal in the humidification device. The touch control button is used to output corresponding touch control signals to the second microcontroller.

[0060] The LED light sets include LED reading light sets and LED sleep aid light sets.

[0061] Users can easily control the reading light by turning it on and off, adjusting brightness, color temperature, and switching modes via touch control buttons, without complicated procedures, making it convenient and quick. The touch control can accurately output corresponding control signals to the second microcontroller, enabling precise adjustment of the light status and meeting users' personalized lighting needs in different scenarios.

[0062] The audio module can play music, audiobooks, etc., providing accompanying sound effects for users while reading, creating a comfortable reading atmosphere, or serving as a sound aid to help them sleep during rest, thus enhancing the user experience.

[0063] LED reading lights provide bright, even light, suitable for reading, helping to protect the eyes and improve reading efficiency; LED sleep aid lights emit soft, warm light, creating a comfortable sleep atmosphere, helping users relax and fall asleep more easily.

[0064] More preferably, such as Figures 8 to 11 As shown, the multi-functional reading light also includes a crystal clock module, a storage module, a power management module, and an analog power supply module that are electrically connected to the second microcontroller;

[0065] The crystal clock module is used to provide a master clock signal for the second microprocessor, the storage module is used to store information, the analog power supply module is used to supply power to the analog pins of the second microprocessor, and the power management module is used to provide various voltage signals.

[0066] More preferably, the power management module includes capacitors C13, C14, C15, C16, and C12, a voltage regulator U2, and a battery; one end of the battery, one end of capacitor C13, and one end of capacitor C14 are electrically connected to the input terminal of voltage regulator U2; one end of capacitor C15, one end of capacitor C16, and the output terminal of voltage regulator U2 are all connected to the 3.3V power supply terminal of the second microcontroller; the ground terminal of voltage regulator U2, the other end of capacitor C15, and the other end of capacitor C16 are all grounded; the power management module is used to convert the 3.7V voltage of the battery to 3.3V voltage, and to power the microcontroller and temperature sensor through the 3.3V voltage;

[0067] The LED driving module includes a resistor R10 and a transistor Q1; the driving terminal of the second microcontroller is electrically connected to the gate of the transistor Q1 and one end of the resistor R10, the other end of the resistor R10 and the source of the transistor Q1 are both grounded, and the drain of the transistor Q1 is electrically connected to the negative terminal of the LED assembly; the positive terminal of the LED assembly is connected to the 3.3V power supply terminal of the second microcontroller.

[0068] The crystal clock module includes a resistor R1, a capacitor C1, a capacitor C2, and a clock chip U1; the clock terminal of the second microcontroller is electrically connected to one end of the resistor R1, the other end of the resistor R1 and one end of the capacitor C1 are connected to the input terminal of the clock chip U1, the ground terminal of the clock chip U1 and the other end of the capacitor C1 are both grounded, and the output terminal of the clock chip U1 is grounded through the capacitor C2.

[0069] In this embodiment, the crystal oscillator clock module provides a stable and accurate master clock signal to the second microprocessor, ensuring time synchronization and coordinated operation among all modules of the multi-functional reading light system. For example, when adjusting the light based on the user's sleep state (determined by combining data such as temperature and heart rate), the crystal oscillator clock module can ensure accurate timing of light adjustments at different stages. For instance, after detecting that the user has entered a sleep state for 5 minutes, it begins to slowly reduce the light brightness at a specific rate, improving the accuracy and reliability of system control.

[0070] Storage module: Capable of storing large amounts of data related to user habits, environmental parameters (such as temperature at different times), and equipment operating status. By analyzing this data, the system can learn user preferences, such as analyzing user choices regarding light brightness and color temperature at different temperatures and times, thereby achieving more intelligent and personalized lighting adjustments. Simultaneously, the stored equipment operating data helps technicians troubleshoot and diagnose equipment malfunctions, quickly pinpointing problems and improving maintenance efficiency.

[0071] The analog power supply module provides a stable power supply to the analog pins of the second microprocessor. Analog circuits have extremely high requirements for power supply stability; even small voltage fluctuations can affect the accuracy and reliability of analog signals. The analog power supply module effectively reduces power supply noise and interference, ensuring the microprocessor's processing accuracy of analog signals (such as the analog temperature signal from the temperature sensing module 74), thereby guaranteeing the accuracy of the entire system's environmental parameter detection and lighting control.

[0072] The power management module in this embodiment uses components such as voltage regulator U2 to convert the single voltage provided by the battery into various voltage signals suitable for different modules, such as providing a stable 3.3V power supply to the second microcontroller. Different modules typically require different supply voltages, and the power management module meets this diverse need, ensuring that each module can operate normally under the appropriate voltage, thus improving system compatibility and overall performance. Capacitors C13, C14, C15, C16, and C12 act as filters, effectively removing noise and ripple in the power supply, making the output voltage smoother and more stable. This is crucial for microcontrollers and other sensitive circuit modules with high voltage stability requirements, reducing system failures and malfunctions caused by voltage fluctuations, improving equipment reliability and stability, and extending equipment lifespan.

[0073] The LED driver module, through a circuit consisting of resistor R10 and transistor Q1, efficiently converts the control signal output from the second microcontroller into a driving current for the LED light group. Transistor Q1 acts as a switch and current amplifier, quickly and accurately controlling the LED light group's on / off state and brightness adjustment based on the microcontroller's drive signal. It features fast response and high control precision, ensuring the LED light group can promptly and accurately present the lighting effects set by the microcontroller.

[0078] Based on the above structure, when the user needs to add water, the aromatherapy device 50 must first be removed from the first connection port 4211 of the water inlet connector 421 to expose the water inlet 4216. Then, the user can inject water into the receiving cavity 4215 through the water inlet 4216.

The atomizing component 43, with its ultrasonic atomizing plate 431 inside the water suction pipe 422, atomizes the water into fine particles. During this process, the atomizing component 43 uses high-frequency vibration to break down water molecules into tiny particles, forming a water mist. The atomized water vapor is then discharged into the indoor air through the mist outlet 4214 on the side wall of the water inlet connector 421 and the mist outlet pipe 423, achieving a humidification effect. The water mist diffuses in the air, increasing air humidity and providing a more comfortable environment for the user.

[0080] The aromatherapy device 50 is detachably sealed at the first connection port 4211 of the water inlet connector 421. The aromatherapy device 50 contains essential oils, which gradually evaporate and release a pleasant fragrance when air flows through or the temperature is suitable. Users can choose different types of essential oils according to their personal preferences and can replace or clean the aromatherapy device 50 at any time.

[0081] In summary, this utility model's reading lamp integrates lighting, humidification, and aromatherapy functions. The aromatherapy device 50 is installed on the humidification device 40, and the two are closely integrated, improving the overall space utilization and making the overall structure of the reading lamp more compact and aesthetically pleasing. Furthermore, users can individually turn the lighting, humidification, and aromatherapy functions on or off as needed, increasing the flexibility of use. In addition, the water inlet 4216 and the detachable aromatherapy device 50 make the product's use and maintenance more convenient.
