Description

Technical Field

[0001] This invention belongs to the field of smart home and health monitoring technology, specifically a smart sleep regulation system that integrates light hypnosis and infrared-sound perception. Background Technology

[0002] In today's fast-paced life, traditional alarm clocks and sleep monitoring devices undoubtedly play a vital role, having an indispensable part in people's daily lives. However, despite their usefulness, their functions and the technologies they employ still have significant limitations. Traditional alarm clocks primarily rely on a single audio stimulus to wake users, most commonly the monotonous ringtone. This method of waking is sudden and intense, like a boulder thrown into a calm lake, often abruptly pulling users from the tranquil world of deep sleep back to wakefulness. This abrupt interruption of sleep can cause strong discomfort, as if being forcibly dragged from a sweet dream. Moreover, this discomfort can further affect a user's mental state throughout the day, potentially leading to fatigue, drowsiness, and difficulty concentrating.

[0003] Meanwhile, while existing sleep monitoring devices possess certain functions and can record users' sleep data to some extent, including basic physiological indicators such as heart rate and respiratory rate, their data analysis capabilities are very limited. They remain at a superficial, basic data level, failing to delve deeper into the meaning behind the data. Moreover, these devices lack the ability to comprehensively regulate sleep cycles and environmental factors; they cannot adjust accordingly based on different sleep cycles the user is in or changes in the surrounding environment.

[0004] Clearly, traditional alarm clocks and sleep monitoring devices only offer basic wake-up functions and limited sleep data analysis. They are like pre-programmed machines, operating only according to fixed patterns, lacking the ability to dynamically adjust the environment based on the user's actual sleep state, and unable to allow the user to wake up naturally at the optimal time. In other words, they cannot automatically create a suitable environment for the user to wake up based on their sleep patterns, ensuring that the user can end their sleep in a comfortable and natural state.

[0005] Therefore, developing a completely new system is particularly important. This system needs to be able to monitor and analyze sleep data in real time, acting like an intelligent sleep manager, constantly monitoring the user's sleep patterns and meticulously analyzing various sleep data. Furthermore, this system should be able to automatically adjust the indoor environment based on the analysis results, such as adjusting indoor lighting, temperature, and humidity, allowing the user to naturally enter a light sleep state at a preset time. In this way, the user can be awakened in a relaxed and comfortable atmosphere, avoiding the discomfort caused by traditional wake-up methods, thus facing the new day with a better mental state.

[0006] Existing intelligent sleep systems primarily rely on monitoring and regulating the physical environment (such as temperature, humidity, light, and sound) to create a suitable sleep environment. However, these systems are inherently passive and responsive, meaning they only adjust the environment when the system detects that the user is in a certain state. They lack the ability to proactively and proactively intervene in the user's core physiological driver—the circadian rhythm (biological clock).

[0007] Circadian rhythms are primarily regulated by light, particularly short-wavelength blue light, through intrinsically photosensitive retinal ganglion cells (ipRGCs) in the retina. Traditional systems simulate natural light variations by controlling the color temperature and brightness of lighting fixtures, but their effectiveness is limited by the spectral characteristics of existing fixtures and they cannot effectively intervene under low-light conditions. Furthermore, the impact of indoor air quality (such as VOCs) on sleep quality has not been adequately considered, and there is a lack of means to combine air purification with photophysiological regulation.

[0008] Therefore, there is an urgent need in this field for an intelligent sleep system that can go beyond simple environmental regulation, directly, proactively, and safely intervene in the user's physiological rhythms, and deeply integrate environmental purification with light health care functions. Summary of the Invention

[0009] To overcome the shortcomings of existing technologies, this invention proposes an intelligent sleep regulation system that integrates photohypnosis and infrared-sound perception. This invention primarily addresses the technical problems of existing intelligent sleep systems that can only passively adapt to the environment, lack proactive and forward-looking physiological intervention on the user's circadian rhythm, and fail to deeply integrate air purification with photophysiological regulation functions.

[0010] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides an intelligent sleep regulation system that integrates light hypnosis and infrared-sound perception, including a data acquisition module, an intelligent analysis and processing module, an environmental control system, and a photocatalytic hypnosis module; The data acquisition module is used to collect the user's physiological state data and sleep environment data in real time; The intelligent analysis and processing module is connected to the data acquisition module and is used to receive and analyze the data to generate a comprehensive control strategy that includes environmental regulation instructions and photocatalytic regulation instructions. The environmental control system is connected to the intelligent analysis and processing module and is used to execute the environmental control instructions to adjust the temperature, humidity, sound and traditional lighting of the sleep environment. The photocatalytic hypnosis module is connected to the intelligent analysis and processing module and is used to receive and execute the photocatalytic regulation command, and actively generate a hypnotic light environment for regulating the user's circadian rhythm through a controlled photocatalytic reaction.

[0011] Preferably, the photocatalytic hypnosis module includes: The photocatalytic reaction unit has nano-photocatalytic materials loaded on its inner wall; A primary light source is used to emit excitation light to the photocatalytic reaction unit, so that the nano-photocatalytic material can undergo a photocatalytic reaction. The optical control unit is used to filter, shape, and guide the light signals generated during the photocatalytic reaction, thereby outputting a hypnotic secondary light source with specific spectral components; The emission spectrum peak of the primary light source is located within the excitation wavelength range of the nano-photocatalytic material, and the main wavelength range of the hypnotic secondary light source is 460nm to 500nm. It is used to stimulate non-visual photoreceptor cells ipRGC to inhibit melatonin secretion, or to be turned off after the sleep preparation stage to promote a natural increase in melatonin.

[0012] Preferably, the nano-photocatalytic material is a TiO2 composite material doped with rare earth elements or a g-C3N4-based composite material. After being excited by the primary light source, it can generate visible light with an intensity higher than the background noise and a wavelength of 480±10nm while degrading organic matter in the air. This visible light serves as the main component of the hypnotic secondary light source.

[0013] Preferably, the optical control unit includes a dynamic spectral filter array and an optical fiber beam guide; the dynamic spectral filter array selects light of a specific wavelength band to pass through according to the instructions of the intelligent analysis and processing module; the optical fiber beam guides the processed hypnotic secondary light source to a diffuser above the user's pillow, forming a localized light environment intervention to avoid disturbing other people in the same room.

[0014] Preferably, the data acquisition module further includes a high-precision light intensity spectral sensor for real-time monitoring of indoor ambient light intensity, color temperature, and spectral power distribution, and transmits the data to the intelligent analysis and processing module; the intelligent analysis and processing module determines the impact of the current natural / artificial light source on the user's circadian rhythm based on this data, and generates corresponding photocatalytic adjustment commands for compensation or synergistic effects.

[0015] Preferably, the intelligent analysis and processing module incorporates a light environment-physiological rhythm coupling model. This model dynamically calculates and outputs photocatalytic regulation commands based on data from the high-precision light intensity spectral sensor, the user's preset sleep schedule, and the current sleep state inferred from infrared / sound data. The command parameters include: the on / off time and luminous intensity of the primary light source, and the spectral selection parameters of the optical control unit, to achieve: In the first period before the user's preset sleep time, the blue light output around 480nm is turned on and enhanced to help reset the biological clock; In the second period before the user's preset sleep time, the blue light output is gradually reduced and turned off, transitioning to long-wavelength warm light to create an environment for melatonin synthesis. During the user's sleep, the photocatalytic sleep-inducing module remains off or operates at low power in an invisible ultraviolet light mode for air purification.

[0016] Preferably, the intelligent analysis and processing module is further used for: When the sound monitor identifies that the user's snoring characteristics match the pathological pattern of sleep apnea syndrome (OSA), a specific photocatalytic intervention instruction is generated. This instruction controls the photocatalytic hypnosis module to generate a low-frequency, softly flickering amber light (wavelength approximately 590nm). This amber light stimulation can slightly penetrate through the user's eyelids to attempt to improve the user's sleep depth and change the pathological state of sleep apnea in a non-disturbing manner.

[0017] Preferably, the system further includes an environmental pollutant sensor for detecting indoor VOCs concentration; the intelligent analysis and processing module controls the primary light source of the photocatalytic hypnosis module to work in the ultraviolet band according to the pollutant concentration data to degrade pollutants with maximum efficiency, while blocking the emission of ultraviolet light and harmful secondary light sources through the optical control unit, and only switching to visible light mode when performing circadian rhythm regulation.

[0018] Preferably, the intelligent analysis and processing module executes the photocatalytic co-wake-up protocol during the daily wake-up phase: While gradually increasing ambient light through the environmental control system, the photocatalytic hypnosis module outputs a secondary light source with a high color temperature (≥5000K) and rich in 480nm blue light. This light source couples with the gradually increasing ambient light and works together on the user to inhibit melatonin in a more physiological way, thereby improving wakefulness comfort and alertness.

[0019] The beneficial effects of this invention are as follows: 1. This invention, through the unique design of a photocatalytic hypnosis module, achieves proactive and forward-looking intervention in the user's circadian rhythm. This module does not simply simulate changes in natural light, but utilizes the innovative method of photocatalysis to actively generate a spectrum with specific physiological regulatory functions. Its core lies in the fact that, under the excitation of a primary light source, the nano-photocatalytic material not only degrades organic matter in the air and purifies the air, but also generates visible light with controllable intensity and precise wavelength, especially blue light around 480nm. This wavelength of light can effectively stimulate the intrinsic photosensitive retinal ganglion cells on the retina, thereby directly regulating melatonin secretion and achieving proactive reset and precise control of the biological clock. This intervention, driven by physiological factors, has a deeper regulatory effect and higher efficiency compared to the passive regulation of environmental physical parameters by traditional systems.

[0020] 2. This invention ingeniously integrates indoor air purification and photophysiological regulation functions into a photocatalytic hypnosis module, achieving multiple benefits in one step. When the environmental pollutant sensor detects excessive indoor VOCs concentration, the intelligent analysis and processing module controls the primary light source to switch to the ultraviolet band. At this time, the nano-photocatalytic material, under ultraviolet light excitation, can efficiently degrade harmful organic compounds in the air, purifying the indoor air. Simultaneously, the optical control unit precisely blocks the emission of ultraviolet light and any potentially harmful secondary light sources, ensuring user safety. When circadian rhythm regulation is needed, the system switches to visible light mode. At this time, the specific wavelength visible light (such as 480nm blue light or long-wavelength warm light) generated by the photocatalytic reaction becomes the "active ingredient" for regulating physiological rhythms. This design allows the photocatalytic hypnosis module to perform the roles of air purification and physiological regulation separately or simultaneously at different stages, greatly improving the system's integration and practicality, and avoiding redundancy of functional modules.

[0021] 3. The data acquisition module in this invention integrates multiple sensors, including infrared, sound, high-precision light intensity spectrum, and environmental pollutant sensors, enabling comprehensive and multi-dimensional real-time perception of the user's physiological state (such as sleep state, snoring, and OSA characteristics) and sleep environment parameters (such as light intensity and VOCs concentration). The intelligent analysis and processing module acts as the system's "brain," incorporating an advanced light environment-physiological rhythm coupling model. This model allows for deep fusion and intelligent analysis of these multi-source data, dynamically generating refined control strategies. Whether it's blue light reset and warm light transition during sleep preparation, ultraviolet purification mode during sleep, high color temperature blue light synergy during wake-up, or even specific amber light intervention for OSA, the system can make precise and dynamic adjustments based on the user's real-time state and preset needs, achieving a leap from passive response to proactive prediction and personalized intervention.

[0022] 4. While pursuing highly efficient physiological intervention, this invention places great emphasis on user safety and comfort. Regarding light output, the system employs an optical control unit to rigorously filter and shape the spectrum, ensuring precise wavelength and appropriate intensity of the output hypnotic secondary light source, thus avoiding potential harm to the user from harmful light components. For example, during sleep, the photocatalytic hypnosis module remains off unless air purification is performed; even when operating in ultraviolet mode, ultraviolet light leakage is blocked. In terms of intervention methods, such as for OSA intervention, low-frequency, softly flickering amber light is used. This light stimulation can penetrate slightly through the eyelids, attempting to improve sleep apnea in a non-disturbing manner, minimizing interference with the user's sleep continuity. During the wake-up phase, a method coupled with gradually increasing ambient light is used to enhance wakefulness comfort in a more physiological way, avoiding the sudden stimulation of a traditional alarm clock. This meticulous consideration of safety and comfort makes the system more user-friendly and easily accepted by users. Attached Figure Description

[0027] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0028] like Figures 1 to 3 As shown, the intelligent sleep regulation system integrating light hypnosis and infrared-sound perception includes a data acquisition module, an intelligent analysis and processing module, an environmental control system, and a photocatalytic hypnosis module. The data acquisition module is used to collect the user's physiological state data and sleep environment data in real time; The intelligent analysis and processing module is connected to the data acquisition module and is used to receive and analyze the data to generate a comprehensive control strategy that includes environmental regulation instructions and photocatalytic regulation instructions. The environmental control system is connected to the intelligent analysis and processing module and is used to execute the environmental control instructions to adjust the temperature, humidity, sound and traditional lighting of the sleep environment. The photocatalytic hypnosis module is connected to the intelligent analysis and processing module, and is used to receive and execute the photocatalytic regulation command. Through a controlled photocatalytic reaction, it actively generates a hypnotic light environment to regulate the user's circadian rhythm. By setting up the photocatalytic hypnosis module, this module can utilize the innovative mechanism of photocatalysis to actively generate a spectrum with specific physiological regulatory functions while purifying the air. This overcomes the limitations of traditional systems that rely solely on physical environmental parameters, and achieves proactive intervention in the user's circadian rhythm.

[0029] In one embodiment of the present invention, the photocatalytic hypnosis module includes: The photocatalytic reaction unit has nano-photocatalytic materials loaded on its inner wall; A primary light source is used to emit excitation light to the photocatalytic reaction unit, so that the nano-photocatalytic material can undergo a photocatalytic reaction. The optical control unit is used to filter, shape, and guide the light signals generated during the photocatalytic reaction, thereby outputting a hypnotic secondary light source with specific spectral components; The emission spectrum peak of the primary light source is located within the excitation wavelength range of the nano-photocatalytic material, and the main wavelength range of the hypnotic secondary light source is 460nm to 500nm. It is used to stimulate non-visual photoreceptor cells ipRGC to inhibit melatonin secretion, or to be turned off after the sleep preparation stage to promote a natural increase in melatonin.

[0030] During operation, the primary light source emits excitation light of a specific wavelength. The spectral peak of this excitation light precisely matches the excitation wavelength of the nano-photocatalytic material loaded on the inner wall of the photocatalytic reaction unit. For example, if a TiO2 composite material doped with rare earth elements is used, the primary light source can be ultraviolet light or visible light of a specific wavelength. When the excitation light irradiates the surface of the nano-photocatalytic material, the material absorbs photon energy and generates electron-hole pairs. These electron-hole pairs undergo a series of complex redox reactions with oxygen, water molecules, etc., in the air, i.e., photocatalytic reactions. In this process, not only can organic matter (such as VOCs) in the air be effectively degraded, playing a role in air purification, but the photocatalytic reaction itself is also accompanied by the generation of light signals of a specific wavelength. For the nano-photocatalytic materials selected in this invention, such as TiO2 composite materials doped with rare earth elements or g-C3N4-based composite materials, after being excited, they can generate visible light with an intensity higher than the background noise and a wavelength concentrated at 480±10nm. This wavelength of light is key to regulating the non-visual photoreceptor cells ipRGC. Subsequently, these light signals enter the optical control unit. Within this unit, a dynamic spectral filter array, based on photocatalytic adjustment commands from the intelligent analysis and processing module, precisely selects and filters out light of specific wavelengths. For example, when melatonin secretion needs to be suppressed for circadian rhythm reset or wake-up, blue light near 480nm is allowed to pass through efficiently. During the sleep preparation stage, the filters are gradually switched to weaken and eventually block blue light, potentially allowing some longer-wavelength warm light to pass through, or directly shutting off visible light output. The filtered and shaped light signals are then efficiently guided by an optical fiber beam to a diffuser above the user's pillow. The diffuser projects the light evenly and softly, creating a localized and precise light environment around the user's eyes, thereby achieving proactive and precise intervention in the user's circadian rhythm while avoiding interference with other people in the room. During this process, if the intelligent analysis and processing module determines that no light environment adjustment is needed and only air purification is required, the primary light source can be switched to a mode that emits only ultraviolet light. At this time, the optical control unit will ensure that ultraviolet light and other potentially harmful secondary light sources are effectively blocked to prevent them from affecting the user.

[0031] In one embodiment of the present invention, the nano-photocatalytic material is a TiO2 composite material doped with rare earth elements or a g-C3N4-based composite material. After being excited by the primary light source, it degrades organic matter in the air while simultaneously generating visible light with an intensity higher than the background noise and a wavelength of 480±10 nm. This visible light serves as the main component of the hypnotic secondary light source. The preparation process of the nano-photocatalytic material is as follows: Taking rare earth element-doped TiO2 composite materials as an example, pure TiO2 sol is first prepared using the sol-gel method. Tetrabutyl titanate is dissolved in anhydrous ethanol, and glacial acetic acid is added as an inhibitor. The mixture is magnetically stirred for 30 minutes to form solution A. Separately, rare earth nitrates (such as Eu(NO3)3·6H2O or Tb(NO3)3·6H2O, with a doping amount of 0.5-2 mol%) are dissolved in a mixed solution of deionized water and anhydrous ethanol to form solution B. Solution B is then slowly stirred under continuous stirring. Slowly add solution A, and after the addition is complete, add an appropriate amount of polyethylene glycol as a dispersant. Continue stirring for 2 hours, and let it stand for 24 hours to obtain a gel. Place the gel in a 60℃ oven to dry for 12 hours, remove the solvent, and obtain a dry gel, which is then ground into powder. Finally, place the powder in a muffle furnace and heat it to 450-550℃ at a heating rate of 5℃ / min. Calcinate for 2-4 hours, and then let it cool naturally to room temperature to obtain a TiO2 nanocomposite material with anatase phase structure doped with rare earth elements.

[0032] For g-C3N4-based composite materials, a thermal polymerization method was used for preparation. Melamine and urea in a specific ratio (mass ratio 1:1-1:3) were mixed evenly and placed in a covered alumina crucible. The temperature was raised to 520℃ at a rate of 2.5℃ / min under a nitrogen atmosphere and held for 3 hours. After natural cooling, a light yellow g-C3N4 powder was obtained. Subsequently, it was treated with an ultrasonic-assisted liquid phase exfoliation method. The g-C3N4 powder was dispersed in deionized water and treated with an ultrasonic power of 300W for 2 hours. The supernatant was collected by centrifugation and dried to obtain a thin layer of g-C3N4. Then, TiO2 quantum dots or ZnO nanoparticles (mass fraction 5-15%) were loaded onto the surface of the thin layer of g-C3N4 by in-situ growth to form a heterojunction structure, which further improved its photocatalytic activity and visible light response range, ensuring stable generation of visible light of 480±10nm under primary light source excitation.

[0033] During operation, when TiO2 composite materials or g-C3N4-based composite materials doped with rare earth elements (such as europium and terbium) are irradiated with excitation light of a specific wavelength emitted by a primary light source (whose spectral peak is within the excitation wavelength range of the nano-photocatalytic material), electrons within the material are excited from the valence band to the conduction band, forming electron-hole pairs. These electron-hole pairs possess extremely strong redox capabilities, rapidly reacting with airborne organic matter (such as formaldehyde, benzene compounds, TVOCs, etc.), water molecules, and oxygen molecules adsorbed on the material surface. In this process, the organic molecules are oxidized and decomposed into harmless carbon dioxide and water, thus purifying the air in the sleeping environment. Simultaneously, for this specific type of nano-photocatalytic material, the doping of rare earth elements or the inherent properties of g-C3N4 not only enhances its photocatalytic activity and absorption capacity for specific wavelengths of light but also facilitates energy transfer and photoluminescence at specific wavelengths during the photocatalytic reaction. Specifically, excited electrons release photons of specific wavelengths during recombination from the conduction band to the valence band, or through energy level transitions of rare-earth ions. In the material system used in this invention, this photon emission is primarily concentrated in the visible light range of 480±10nm, and its intensity is optimized to be significantly higher than the background noise light intensity in the environment, ensuring it is perceived as an effective physiological signal. This visible light with a wavelength of 480±10nm is specifically perceived and absorbed by the intrinsically photosensitive retinal ganglion cells (ipRGCs) on the retina, thus becoming a core component of the hypnotic secondary light source, responsible for transmitting key light signals that regulate the user's circadian rhythm. This allows the photocatalytic hypnosis module to cleverly achieve the function of physiological rhythm light regulation while purifying the air, truly achieving a deep integration and synergistic work between air purification and photophysiological regulation.

[0034] In one embodiment of the present invention, the optical control unit includes a dynamic spectral filter array and an optical fiber beam guide; the dynamic spectral filter array selects light of a specific wavelength band to pass through according to the instructions of the intelligent analysis and processing module; the optical fiber beam guides the processed hypnotic secondary light source to a diffuser above the user's pillow, forming a localized light environment intervention to avoid disturbing other people in the same room.

[0035] During operation, the optical control unit, as the core component of the photocatalytic hypnosis module, precisely controls the light output, and its workflow closely coordinates with the instructions of the intelligent analysis and processing module. First, the dynamic spectral filter array receives photocatalytic adjustment instructions from the intelligent analysis and processing module, which contain the currently required spectral composition parameters. The dynamic spectral filter array consists of a series of independently controllable micro-electronic filters, each corresponding to a specific spectral transmission range. Based on the user's current physiological state (such as wakefulness, preparing to fall asleep, or deep sleep inferred from infrared / sound data), the preset sleep schedule, and the ambient light conditions monitored by the high-precision light intensity spectral sensor, the intelligent analysis and processing module calculates and determines the optimal hypnotic secondary light source spectrum. For example, during the first period before the user's preset sleep time, if a biological clock reset is needed, the command will control a specific filter in the array to switch to a state that allows efficient transmission of blue light around 480nm. When entering the second period before the preset sleep time, when melatonin synthesis needs to be promoted, the command will drive the filter array to gradually switch to a state that blocks blue light or only allows weak transmission of long-wavelength warm light (such as red or orange light greater than 600nm), and even completely shut down the visible light pathway in some cases. This switching is real-time and continuously adjustable to ensure a smooth spectral transition and avoid causing light stimulation interference to the user.

[0036] After the dynamic spectral filter array filters and shapes the original light signal generated by the photocatalytic reaction unit, the resulting light signal with specific spectral components enters the fiber optic guide beam. The fiber optic guide beam consists of multiple bundles of high-transmittance quartz or plastic optical fibers, with its input end precisely aligned with the output port of the dynamic spectral filter array to maximize the collection and transmission of the processed light signal. The output end of the fiber optic guide beam is connected to a diffuser installed at a specific location above the user's pillow. The diffuser, typically made of frosted glass, milky acrylic, or microstructured optical elements, effectively scatters and homogenizes the concentrated light beam transmitted from the fiber optic guide beam, resulting in uniform and soft projected light, creating a localized light environment centered on the user's eyes and covering the area near their head. This localized design ensures that the light environment intervention precisely targets the user, with the light intensity reaching an effective physiological regulation threshold in the user's eye area, while attenuating to a negligible level in areas occupied by other people in the room, effectively avoiding any unnecessary interference with the sleep or activities of others in the room. For example, when a user wakes up at night and the system needs to briefly turn on low-intensity, specific-spectrum light to soothe or help them fall back asleep, this localized lighting environment will not illuminate the entire bedroom, ensuring that the sleep of other roommates is not disturbed. At the same time, the diffuser's soft light effect avoids the discomfort that direct light might cause to the user's eyes, enhancing the user experience.

[0037] As one embodiment of the present invention, the data acquisition module further includes a high-precision light intensity spectral sensor for real-time monitoring of the light intensity, color temperature and spectral power distribution of indoor ambient light, and transmitting the data to the intelligent analysis and processing module; the intelligent analysis and processing module determines the impact of the current natural / artificial light source on the user's circadian rhythm based on this data, and generates corresponding photocatalytic adjustment commands for compensation or synergistic effects.

[0038] During operation, the high-precision light intensity spectral sensor continuously samples indoor ambient light at a sampling frequency of no less than 1 Hz, capturing data on illuminance (in lux), color temperature (in K), and continuous spectral power distribution within the visible light range of 380 nm to 780 nm. This data is transmitted in real-time to the intelligent analysis and processing module via wired or low-power wireless means. The intelligent analysis and processing module first preprocesses the received raw spectral data, including background noise reduction, spectral smoothing, and standard light source calibration, to ensure data accuracy. Subsequently, the module's built-in circadian rhythm light effect evaluation algorithm calculates the melanopic equivalent illuminance (melanopic EDI), which has a strong stimulating effect on iPRGC cells, and the circadian rhythm stimulation value (CS), which characterizes the influence of the biological clock, based on the spectral power distribution. For example, when the sensor detects insufficient indoor natural light during the day and the melanopic EDI is below 300 lux, the intelligent analysis and processing module determines that the current ambient light may not be sufficient to effectively suppress melatonin secretion, thereby affecting the user's wakefulness and daytime alertness. At this point, the module generates a synergistic enhancement command, controlling the optical control unit of the photocatalytic hypnosis module to switch to a visible light mode rich in 480nm blue light. It also dynamically adjusts the blue light intensity and overall output power of the secondary light source based on real-time ambient light spectral data, ensuring the total melanopic EDI reaches the ideal range of 500-1000 lux to compensate for insufficient natural light and synergistically enhance the daytime reset effect of the biological clock. Conversely, if, during the second period before the preset sleep time, the sensor detects a strong blue light component in the room (such as light from electronic device screens), with a significant peak in its spectral power distribution near 480nm, the intelligent analysis and processing module generates a compensation inhibition command. This command further reduces the blue light output of the photocatalytic hypnosis module and may appropriately increase the proportion of long-wavelength warm light to counteract the interference of excess blue light in the ambient light on melatonin synthesis, ensuring the user can smoothly enter a natural sleep state at the preset sleep time. In addition, when the system executes the wake-up protocol, the high-precision light intensity spectral sensor monitors the changes in ambient light enhanced by the environmental control system in real time. The intelligent analysis and processing module fuses this change data with the high color temperature secondary light source data output by the photocatalytic hypnosis module, and dynamically adjusts the light intensity and spectral ratio of the two to ensure that the rate of change and spectral composition of the light environment during the entire wake-up process conforms to the natural curve of human physiological wake-up, avoiding discomfort caused by sudden changes in light, and achieving true physiological synergistic wake-up.

[0039] In one embodiment of the present invention, the intelligent analysis and processing module incorporates a light environment-physiological rhythm coupling model. This model dynamically calculates and outputs photocatalytic regulation commands based on data from the high-precision light intensity spectral sensor, the user's preset sleep schedule, and the current sleep state inferred from infrared / sound data. The command parameters include: the on / off time and luminous intensity of the primary light source, and the spectral selection parameters of the optical control unit, to achieve: In the first period before the user's preset sleep time, the blue light output around 480nm is turned on and enhanced to help reset the biological clock; In the second period before the user's preset sleep time, the blue light output is gradually reduced and turned off, transitioning to long-wavelength warm light to create an environment for melatonin synthesis. During the user's sleep, the photocatalytic sleep-inducing module remains off or operates at low power in an invisible ultraviolet light mode for air purification.

[0040] During operation, the intelligent analysis and processing module first fuses and initializes multi-source data. It reads user-preset sleep schedule data via the accompanying app or physical buttons on the device, such as a set sleep time of 11:00 PM and a wake-up time of 7:00 AM. Based on this, the day is divided into several key time periods, such as the 2-hour circadian rhythm reinforcement period after waking up, the first period 90 minutes before the preset sleep time (e.g., 9:30 PM - 10:00 PM), the second period 30 minutes before the preset sleep time (e.g., 10:30 PM - 11:00 PM), the sleep period (11:00 PM - 7:00 AM), and the wake-up period (e.g., 7:00 AM - 7:30 AM). Simultaneously, the module continuously receives real-time data from the infrared / sound sensing unit. Through feature extraction and pattern recognition algorithms, it accurately infers the user's current sleep state, such as whether they are awake, relaxed, in light sleep, in deep sleep, or in REM sleep. A high-precision light intensity spectral sensor provides real-time baseline data of the indoor ambient light.

[0041] Based on the above data input, the light environment-physiological rhythm coupling model begins to operate. At its core is a series of dynamic equations and decision trees trained with extensive physiological experimental data. This model can simulate the effects of different light environment parameters (spectrum, intensity, duration of exposure) on the human melatonin secretion curve, core body temperature rhythm, and sleep structure. For example, based on the user's age, preset wake-up time, and the current ambient light's melatonin EDI value, the model calculates the target melatonin EDI value to be achieved in the first period before the preset sleep time (21:30-22:00). This ensures sufficient intensity of 480nm blue light stimulates iPRGC cells, effectively inhibiting premature melatonin secretion and helping the user anchor their biological clock to the preset sleep schedule. At this point, the photocatalytic adjustment instructions output by the model will include: the primary light source emitting excitation light of a specific wavelength at a higher power (e.g., 70%-90% of its rated power) to ensure that the nano-photocatalytic material produces 480±10nm visible light of sufficient intensity; the dynamic spectral filter array of the optical control unit switches to the "blue light enhancement" mode, allowing light in the 470-490nm band to pass through with a transmittance of more than 90%, and may simultaneously suppress light in other non-target bands.

[0042] As time progresses, during the second period before the preset sleep time (22:30-23:00), the light environment-physiological rhythm coupling model initiates a blue light attenuation program based on the remaining sleep preparation time and the expected time when melatonin levels begin to rise. At this time, the model dynamically adjusts the luminous intensity of the primary light source (e.g., gradually and linearly reducing it from 70% power to 20%), referencing the current indoor blue light level monitored by a high-precision light intensity spectral sensor. It also instructs the dynamic spectral filter array of the optical control unit to gradually switch filter combinations, gradually reducing the transmittance of 480nm blue light from 90% to 0%, while potentially allowing 590-650nm warm red light to pass through with 10%-30% transmittance, creating a dim, warm light environment conducive to melatonin synthesis. This transition process is typically smooth and slow, lasting 20-30 minutes, to simulate the light changes of a natural sunset and avoid abrupt changes in light signals that could stimulate the user.

[0043] When the preset sleep time (11:00 PM) is reached, if infrared / sound data indicates that the user has successfully entered a light sleep state, the intelligent analysis and processing module will instruct the primary light source to turn off the visible light excitation mode or switch to a low-power mode that emits only ultraviolet light (e.g., 10%-20% of its rated power). At this time, the optical control unit will ensure that all visible light (including any secondary light sources that may be generated) is completely blocked, allowing only the photocatalytic reaction to take place internally to continuously purify the air. Throughout the sleep period (11:00 PM - 7:00 AM), the model will continuously monitor the user's sleep status. If the infrared / sound sensor detects that the user experiences brief awakenings or an increased number of times they toss and turn, it may be judged that the air quality in the sleep environment has decreased or there is slight external interference. In this case, the ultraviolet light power of the primary light source may be briefly increased to enhance the air purification effect without turning on visible light, but strict light leakage is ensured throughout the process.

[0044] Before the preset wake-up time (e.g., 30 minutes before 7:00 AM), the intelligent analysis and processing module begins executing the wake-up protocol. The light environment-physiological rhythm coupling model, based on the user's desired wake-up time and current sleep cycle stage (inferred from infrared / sound data, prioritizing light sleep), instructs the primary light source to restart and gradually increase its power. The dynamic spectral filter array of the optical control unit switches to a "high color temperature wake-up" mode, allowing 480nm blue light and 500-600nm green light components to pass through, simulating the spectral changes at sunrise. The model controls the light intensity to gradually and linearly increase from an almost invisible low level (e.g., 10 lux) to the target wake-up light intensity (e.g., 500-1000 lux melanopic EDI), with the rate of change strictly following the optimal curve for human biological clock wake-up. This ensures a natural and comfortable transition from deep sleep to wakefulness, avoiding the sleep inertia caused by the sudden stimulation of traditional alarm clocks. During this process, a high-precision light intensity spectral sensor provides real-time feedback on ambient light changes, allowing the model to fine-tune the photocatalytic regulation commands, achieving closed-loop precise control.

[0045] In one embodiment of the present invention, the intelligent analysis and processing module is further used for: When the sound monitor identifies that the user's snoring characteristics match the pathological pattern of sleep apnea syndrome (OSA), a specific photocatalytic intervention instruction is generated. This instruction controls the photocatalytic hypnosis module to generate a low-frequency, softly flickering amber light (wavelength approximately 590nm). This amber light stimulation can slightly penetrate through the user's eyelids to attempt to improve the user's sleep depth and change the pathological state of sleep apnea in a non-disturbing manner.

[0046] During operation, the sound monitor continuously collects sound signals from the user's sleep process at a sampling frequency of no less than 20Hz. The collected raw audio signals are first processed by bandpass filtering to remove 50Hz / 60Hz power frequency interference and high-frequency noise above 10kHz. Then, the time-domain signal is converted into a frequency-domain signal through Fast Fourier Transform (FFT) to extract the characteristic parameters of snoring, including the duration of snoring (e.g., a single snoring lasting more than 10 seconds), the interval period (e.g., apnea time exceeding 15 seconds and accompanied by a low ventilation index), the fundamental frequency range (usually between 50-500Hz), and the sound pressure level change (e.g., explosive snoring exceeding 60dB). These characteristic parameters are transmitted in real time to the intelligent analysis and processing module. The module's built-in OSA pathological pattern recognition algorithm compares the current characteristic parameters with preset OSA typical templates (e.g., obstructive, central, or mixed types). When snoring events matching OSA pathological characteristics are detected 3 times consecutively or 5 times cumulatively within 5 minutes, the system determines that the user may have sleep apnea. At this moment, the intelligent analysis and processing module immediately initiates an emergency intervention program, generating a specific photocatalytic intervention command. This command first controls the primary light source to switch to a specific wavelength excitation mode, driving the photocatalytic reaction unit to generate an amber light signal with a center wavelength of 590nm±10nm. Then, it commands the dynamic spectral filter array to switch to a state that allows efficient transmission of this wavelength (transmittance >85%) while strictly blocking stray light of other wavelengths. Simultaneously, it precisely controls the driving current of the primary light source, maintaining the output light intensity at an extremely low level of 0.5-2 lux, and slowly flickering at a low frequency of 0.5-1Hz (duty cycle 50%). The processed amber flickering light signal is transmitted to the diffuser via an optical fiber beam, forming a soft, uniform local light environment that weakly acts on the retina through the user's closed eyelids (the eyelids have a transmittance of approximately 10%-20% for 590nm wavelength light). This specific wavelength and frequency of light stimulation aims to activate specific photoreceptor cell pathways in the retina non-invasively, indirectly affecting the neural regulation of the brainstem respiratory center, promoting the recovery of upper respiratory tract muscle tone, or slightly increasing the user's sleep arousal threshold, thereby alleviating sleep apnea symptoms. During the intervention, the sound monitor continuously collects and analyzes snoring signals. If no snoring of the OSA pathological pattern is detected for two consecutive minutes, the intelligent analysis and processing module instructs the photocatalytic hypnosis module to gradually reduce the flashing frequency and intensity of the amber light until the intervention light source is completely turned off to avoid continuous light stimulation affecting the user's subsequent sleep. If the OSA symptoms are still not relieved after a certain period of 5 minutes, the module will activate a secondary warning mechanism, sending a reminder message to the user's preset emergency contacts through the accompanying APP, and attempting to wake the user on the local device with extremely weak vibration (non-sound) to prevent severe hypoxia events.

[0047] As one embodiment of the present invention, the system further includes an environmental pollutant sensor for detecting indoor VOCs concentration; the intelligent analysis and processing module controls the primary light source of the photocatalytic hypnosis module to work in the ultraviolet band according to the pollutant concentration data to degrade pollutants with maximum efficiency, while blocking the emission of ultraviolet light and harmful secondary light sources through the optical control unit, and only switching to visible light mode when performing circadian rhythm regulation.

[0048] During operation, the environmental pollutant sensor (such as a PID-based or metal-oxide-semiconductor sensor) continuously monitors the concentration of volatile organic compounds (VOCs) in indoor air, such as formaldehyde, benzene compounds, and TVOC, at a preset sampling interval (e.g., once every 30 seconds), and transmits the real-time data to the intelligent analysis and processing module. The intelligent analysis and processing module compares the received VOC concentration values ​​with a preset safety threshold (e.g., TVOC concentration of 0.6 mg / m³). 3 The system compares the VOC concentration with the ambient light source. When the VOC concentration is detected to be below the safety threshold, and the system is not currently in a period of light environment adjustment (i.e., not executing protocols requiring visible light such as sleep preparation, wake-up, or OSA intervention), the intelligent analysis and processing module prioritizes the photocatalytic purification function by default. At this time, the module generates an ultraviolet light purification command, controlling the primary light source of the photocatalytic hypnosis module to switch to the ultraviolet band (usually 254nm or 185nm) working mode, and dynamically adjusts its output power according to the concentration of pollutants. For example, when the VOC concentration is between 0.3-0.6 mg / m³... 3 Within the sub-safe range, the primary light source operates at 50%-70% of its rated ultraviolet power; if the concentration approaches or slightly exceeds the safety threshold, the rated power is increased to 80%-100% to maximize the excitation efficiency of the nano-photocatalytic material (such as TiO2) and generate sufficient hydroxyl radicals (·OH) and superoxide anion radicals (·O2). - This system efficiently degrades VOCs in the air. Simultaneously, the intelligent analysis and processing module strictly controls the optical control unit, ensuring its dynamic spectral filter array switches to "UV blocking and secondary light absorption" mode. In this mode, the filter's transmittance to primary UV light sources can be as low as 0.1%, and it can effectively absorb any short-wavelength harmful secondary light sources (such as the weak fluorescence emitted by some reactive oxygen species) that may be generated during the photocatalytic reaction. This ensures that only purified air is discharged through a specific air duct, without any UV light or other harmful light leaking into the user's living space, thus protecting user safety.

[0049] When the high-precision light intensity spectral sensor detects the need for circadian rhythm adjustment (such as entering a preset first / second sleep period or wake-up period), or when the infrared / sound sensing unit triggers the OSA intervention mechanism, the intelligent analysis and processing module will prioritize functions. At this time, even if the environmental pollutant sensor shows that the VOCs concentration has not completely decreased to the ideal value, the module will temporarily prioritize the light environment adjustment needs, placing the photocatalytic purification function in a secondary position. It will instruct the primary light source to switch from the ultraviolet band to the corresponding visible light mode (such as blue light enhancement, warm red light, or amber intervention light) and control the optical control unit to adjust the filter array to match the currently required spectral output. During this period, if the VOCs concentration is still higher than the safety threshold, the intelligent analysis and processing module will optimize the energy distribution of the primary light source as much as possible without affecting the current light environment adjustment effect. For example, within the allowable range of visible light output power, it may appropriately retain some ultraviolet excitation capability, or briefly activate ultraviolet light for rapid purification during the visible light mode switching intervals. Once the circadian rhythm adjustment task is completed (e.g., the user is asleep and OSA intervention is unnecessary, or the wake-up process is finished), the intelligent analysis and processing module will immediately instruct the system to return to the ultraviolet light purification mode until the VOCs concentration drops below the safe threshold, and maintain a low-power ultraviolet cruise purification state to maintain indoor air quality. Furthermore, the system has learning capabilities; the intelligent analysis and processing module records the VOCs concentration changes at different times and the user's daily routines. Therefore, during periods when the user does not typically adjust the light environment (e.g., when the user is out working during the day), it automatically increases the operating power and duration of the ultraviolet light purification for deep purification, ensuring that the indoor environment meets both physiological rhythm requirements and air cleanliness standards when the user returns.

[0050] In one embodiment of the present invention, the intelligent analysis and processing module executes a photocatalytic co-wake-up protocol during the daily wake-up phase: While gradually increasing ambient light through the environmental control system, the photocatalytic hypnosis module outputs a secondary light source with a high color temperature (≥5000K) and rich in 480nm blue light. This light source couples with the gradually increasing ambient light and works together on the user to inhibit melatonin in a more physiological way, thereby improving wakefulness comfort and alertness.

[0051] At work, The intelligent analysis and processing module first confirms that the user is in a light sleep stage (e.g., stable breathing rate, minimal body movement, and duration exceeding 5 minutes) through the infrared / sound sensing unit. Then, it simultaneously sends a coordinated wake-up command to both the environmental control system and the photocatalytic hypnosis module. Upon receiving the command, the environmental control system activates its built-in main light source (e.g., a simulated sunrise light installed on the ceiling), starting from an initial light intensity (e.g., 5 lux, color temperature 2700K) according to a preset wake-up curve, slowly increasing the light intensity at a rate of 5-10 lux per minute, while simultaneously linearly increasing the color temperature from 2700K to over 5000K, simulating the natural light changes from dawn to sunrise. At the same time, the intelligent analysis and processing module of the photocatalytic hypnosis module instructs the primary light source to switch to the "high color temperature synergistic awakening" mode, driving the nano-photocatalytic material to generate a composite beam of blue light with a peak wavelength of 480±5nm and green light with a peak wavelength of 500-600nm. At this time, the dynamic spectral filter array of the optical control unit switches to a specific combination to ensure that the transmittance of 480nm blue light reaches more than 85%, the transmittance of 500-600nm green light reaches 70%-80%, while the transmittance of red light above 600nm is limited to less than 10%, forming a secondary light source with a high color temperature (≥5000K). The secondary light source transmits light to the bedside diffuser via fiber optic beams, focusing the illumination at a 30°-45° angle onto the area around the user's eyes (but avoiding direct light to the eyeballs). The initial light intensity is set to 10%-15% of the current light intensity of the environmental control system (for example, when the ambient light intensity reaches 50 lux, the secondary light source contributes 5-7.5 lux of directional blue light stimulation), and increases linearly in sync with the increase in ambient light intensity. Finally, at the end of the wake-up phase (i.e., the preset wake-up time of 7:00), the melanopic EDI value of the secondary light source reaches 20%-25% of the total ambient light intensity (for example, when the ambient light intensity is 500 lux, the secondary light source provides 100-125 lux of melanopic EDI contribution). The advantage of this dual-light source coupling mechanism is that the environmental control system provides the overall brightness and color temperature atmosphere of the space, while the secondary light source of the photocatalytic hypnosis module precisely targets the iPRGC cells of the retina. By enhancing the local stimulation intensity of 480nm blue light, it accelerates the inhibition efficiency of melatonin (compared to single ambient light, the rate of melatonin decline can be increased by 15%-20%).Meanwhile, the intelligent analysis and processing module receives real-time environmental total spectrum data from a high-precision light intensity spectral sensor and dynamically adjusts the blue / green light ratio of the secondary light source to ensure that the spectral energy distribution of both always conforms to the "natural sunrise spectrum simulation curve"—for example, in the early stage of wake-up (6:30-6:40), the proportion of green light is slightly higher than that of blue light (approximately 55%:45%) to gently activate the visual pathway; in the middle stage of wake-up (6:40-6:50), the proportion of blue light gradually increases to 55%-60% to strengthen the biological clock reset signal; in the late stage of wake-up (6:50-7:00), the ratio of blue light to green light stabilizes at 50%:50%, which, together with the high color temperature of the ambient light, enhances the user's alertness and cognitive performance. In addition, the collaborative wake-up protocol will also be personalized by combining the user's historical sleep data: if the user's deep sleep rate is insufficient (<25%) the previous night, the module will appropriately reduce the intensity of blue light stimulation from the secondary light source (reduce by 5%-10%) and extend the wake-up transition time by 5-10 minutes to avoid overstimulation; if the user is in a deep sleep cycle (body movement frequency detected by infrared sensor <1 time / 10 minutes and breathing amplitude is uniform), the activation of the secondary light source will be temporarily delayed until the light intensity of the environmental control system reaches more than 100 lux and the user enters a light sleep state, and then the directional blue light stimulation will be turned on to ensure the comfort and effectiveness of the wake-up process.

[0052] General Working Principle: Within the user's preset sleep cycle, the system constructs a multimodal sleep state perception network through infrared sensors and sound monitors. It captures physiological signals such as the user's body movement amplitude, respiratory rate, and snoring characteristics in real time. Combined with ambient light parameters fed back by a high-precision light intensity spectral sensor, the intelligent analysis and processing module integrates the data and drives the core functional modules to work collaboratively. During the sleep-onset stage, the intelligent analysis and processing module initiates the photo-hypnosis process based on the user's set bedtime or through behavioral perception (such as the user lying in bed and the ambient light dimming). It controls the photocatalytic hypnosis module to sequentially output warm red-toned (wavelength 620-660nm) initial guide light, gradually reducing the color temperature to below 2200K. Simultaneously, it works with the environmental control system to create a low-brightness environment of 15-30 lux, and activates the white noise generation unit (if the user has enabled this function) to improve sleep-onset efficiency through sound masking. During this process, environmental pollutant sensors continuously monitor indoor VOCs concentration, and the intelligent analysis and processing module dynamically balances photocatalytic purification and photo-hypnosis functions. If the pollutant concentration exceeds the standard, the ultraviolet light mode is used to degrade the pollutants first, and after the concentration drops to a safe threshold, it seamlessly switches to the visible light hypnosis mode to ensure that air purification and sleep aid effects are achieved simultaneously.

[0053] Once the system detects that the user has entered a stable sleep state (cessation of body movement, even breathing), it automatically switches to sleep maintenance mode. At this time, the photocatalytic hypnosis module turns off visible light output by default. If the concentration of environmental pollutants does not reach the ideal value, low-power ultraviolet light continues to purify the air, and the optical control unit strictly blocks ultraviolet leakage. During this period, the sound monitor continuously analyzes snoring signals at a sampling frequency of 20Hz or higher. Once characteristic parameters consistent with the OSA pathological pattern are identified (such as snoring lasting more than 10 seconds accompanied by 15 seconds of breathing apnea), amber low-frequency flickering light (590nm±10nm, 0.5-2lux, 0.5-1Hz) is immediately triggered to intervene, penetrating the retina through the eyelids to attempt to regulate the respiratory center function. During the intervention, changes in snoring are continuously monitored. If the snoring is relieved within 2 minutes, the intervention light source is gradually turned off. If the snoring is not relieved within 5 minutes, a level two warning is activated.

[0054] 30-45 minutes before the preset wake-up time, the system enters the coordinated wake-up phase: the simulated sunrise light of the environmental control system starts from a low color temperature (2700K) and low light intensity (5 lux), linearly increasing to a high color temperature above 5000K and a light intensity above 500 lux; simultaneously, the photocatalytic hypnosis module outputs a high color temperature (≥5000K) secondary light source, precisely enhancing the 480nm blue light component (transmittance >85%), and directing it to the eye area through fiber optic beams, coupling with ambient light to form a dual-path stimulation of "overall atmosphere + local targeting", accelerating melatonin inhibition and biological clock activation. During the wake-up process, the intelligent analysis and processing module dynamically adjusts the blue light intensity and the slope of the wake-up curve according to the user's historical sleep structure (such as the proportion of deep sleep and sleep cycles) to ensure a balance between wake-up comfort and alertness. Throughout the entire working cycle, the system achieves intelligent and personalized regulation of the sleep environment and physiological state through a closed-loop feedback mechanism (real-time sensor data → algorithm analysis → module parameter adjustment → effect re-monitoring). It integrates the dual characteristics of purification and light regulation of photocatalysis technology to achieve full-process sleep health management of "environmental purification - sleep monitoring - abnormal intervention - natural awakening".
