Description

Technical Field

[0001] This invention relates to the field of lighting device design technology, and in particular to an intelligent sleep-aiding and wake-up lighting system. Background Technology

[0002] Sleep quality has a significant impact on human health and daytime mental state. Light, as a key environmental factor influencing the body's biological clock and sleep rhythm, directly affects sleep onset efficiency and wakefulness. Currently, common bedroom lighting devices mainly provide basic lighting functions, such as manual switches, brightness adjustment, or preset color temperature switching, offering relatively limited functionality. Although some lighting products on the market have "sleep aid" or "wake-up" modes, such as gradually dimming the light or simulating sunrise light by controlling the timer, these solutions are mostly based on fixed time programs and cannot dynamically adjust according to the user's actual sleep cycle and physiological state.

[0003] In practical use, individual users have different sleep onset times, sleep stages, and environmental conditions. Relying solely on fixed-sequence control often leads to the following problems: the light is turned off according to the preset program before the user has entered a relaxed state, making it difficult to fall asleep; or the wake-up light is prematurely increased while the user is still in deep sleep, causing discomfort upon waking or even sleep interruption. In addition, ambient light, noise, and other factors can also interfere with the sleep process, and traditional lighting systems lack the ability to comprehensively perceive and respond to environmental information, failing to provide appropriate sleep aid or wake-up support in complex environments.

[0004] Therefore, existing lighting devices are significantly inadequate in "automatically adjusting light according to the sleep cycle," lacking the ability to intelligently perceive and adaptively regulate the user's real-time physiological state and sleep environment, making it difficult to truly improve the user's sleep and wake-up experience.

[0005] Therefore, there is an urgent need for an intelligent lighting system that can comprehensively sense the user's state and environmental conditions, and dynamically adjust the brightness and color temperature of the light accordingly, in order to achieve a more natural and comfortable sleep aid and wake-up process. Summary of the Invention

[0006] This invention discloses an intelligent sleep-aiding and wake-up lighting system to solve the technical problem that existing lighting devices lack the ability to intelligently perceive and adaptively regulate the user's real-time physiological state and sleep environment, making it difficult for them to truly improve the user's sleep and wake-up experience.

[0007] The present invention provides an intelligent sleep-aiding and wake-up lighting system, comprising a control module, an environmental sensing module and an adjustable light source module, all electrically connected to the control module;

[0008] The environmental perception module includes at least a bio-radar for detecting the user's vital signs, an ambient light sensor for detecting the illuminance of the sleep environment, and a sound sensor for detecting the noise intensity of the sleep environment.

[0009] The control module is used to determine whether to activate the sleep aid mode or the wake-up mode based on the user's vital signs information detected by the bio-radar, the sleep environment light intensity information detected by the ambient light sensor, and the ambient noise intensity detected by the sound sensor.

[0010] The adjustable light source module is used to output light with adjustable brightness and color temperature based on the sleep aid mode or wake-up mode.

[0011] Optionally, when the control module activates the sleep aid mode, the adjustable light source module, according to a first preset program, smoothly and gradually changes the brightness and color temperature of the light from a first state to a second state within a first time period.

[0012] When the control module activates the wake-up mode, the adjustable light source module, according to the second preset program, smoothly transitions the brightness and color temperature of the light from the second state to the first state within a first time period.

[0013] Optionally, the first state is:

[0014] The adjustable light source module emits light with a brightness range of 500lx-700lx and a cool color temperature range of 4000K-5000K.

[0015] The second state is:

[0016] The adjustable light source module emits light with a brightness range of 10lx-50lx and a warm color temperature range of 1500K-2800K.

[0017] Optionally, the control module is further configured to dynamically adjust the execution parameters of the first preset program based on the user's vital signs information monitored by the bio-radar during the first time period when the sleep aid mode is activated.

[0018] Optionally, the dynamic adjustment of the execution parameters of the first preset program specifically includes:

[0019] If, based on the feedback from the bio-radar, it is determined that the user has not entered a static and relaxed state within the first time period, the total duration of the first time period is extended, or the adjustable light source module is controlled to output a brightness fluctuation mode.

[0020] Optionally, the brightness fluctuation mode is specifically as follows:

[0021] The light output by the adjustable light source module fluctuates at a low frequency within the brightness range of 10lx-500lx.

[0022] Optionally, when the bio-radar detects that the user has entered a static and relaxed state for more than a first time threshold, the ambient light intensity detected by the ambient light sensor is lower than a first light threshold, the ambient noise detected by the sound sensor is lower than a first sound threshold, and the sum of the values ​​of the first time threshold, the first light threshold, and the first sound threshold is less than a first preset comprehensive threshold, the control module activates the sleep aid mode.

[0023] Optionally, the bio-radar can detect whether the user is in a deep sleep or light sleep stage;

[0024] When the bio-radar detects that the user is in a light sleep period exceeding a second time threshold, the ambient light intensity detected by the ambient light sensor is higher than a second light threshold, the ambient noise detected by the sound sensor is higher than a second sound threshold, and the sum of the values ​​of the second time threshold, the second light threshold, and the second sound threshold is greater than a second preset comprehensive threshold, the control module activates the wake-up mode.

[0025] Optionally, the user's vital signs information detected by the bio-radar includes body movement index, heart rate index, and respiratory index;

[0026] The bio-radar detects that the user's kinematic index is less than 10, heart rate is 60-80 beats / minute, and respiratory rate is 12-18 breaths / minute, and this condition is maintained for at least 5 minutes, and then determines that the user is in a state of rest and relaxation.

[0027] The bio-radar detects that the user's kinematic index is between 10 and 30, heart rate is between 60 and 80 beats per minute, and respiratory rate is between 12 and 18 breaths per minute, and this condition is maintained for at least 3 minutes, indicating that the user is in a light sleep stage.

[0028] The bio-radar detects that the user's kinematic index is less than 10, heart rate is between 50 and 70 beats per minute, and respiratory rate is between 10 and 14 breaths per minute, and this condition persists for at least 5 minutes, indicating that the user is in a deep sleep period.

[0029] Optionally, it may also include a user interaction module;

[0030] The user interaction module is electrically connected to the control module and is used to receive configuration information input by the user, including at least preset sleep time and preset wake-up time.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] In the intelligent sleep-aid and wake-up lighting system of this invention, bio-radar monitors the user's vital signs in real time. Combined with ambient light and noise sensor information, the control module can accurately determine whether the user is in the sleep preparation stage or awake state, and automatically trigger the sleep-aid mode or wake-up mode accordingly, achieving dynamic synchronization between light and the user's sleep cycle. Furthermore, because the lighting system integrates data from multiple environmental sensors, the system will only activate the sleep-aid or wake-up program when the lighting is suitable, the noise is low, and the user's state meets the conditions, effectively preventing false triggering, improving usability in different sleep environments, and greatly enhancing the user's sleep and wake-up experience.

[0036] This invention discloses an intelligent sleep-aiding and wake-up lighting system to solve the technical problem that existing lighting devices lack the ability to intelligently perceive and adaptively regulate the user's real-time physiological state and sleep environment, making it difficult for them to truly improve the user's sleep and wake-up experience.

[0037] To enable those skilled in the art to better understand the present invention, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figure 1 The present invention provides an intelligent sleep-aiding and wake-up lighting system, including a control module 1, an environmental sensing module 3 and an adjustable light source module 2, all of which are electrically connected to the control module 1.

[0039] The environmental perception module 3 includes at least a bio-radar 301 for detecting the user's vital signs, an ambient light sensor 302 for detecting the illuminance of the sleep environment, and a sound sensor 303 for detecting the noise intensity of the sleep environment.

[0040] The control module 1 is used to determine whether to activate the sleep aid mode or the wake-up mode based on the user's vital signs information detected by the bio-radar 301, the sleep environment light intensity information detected by the ambient light sensor 302, and the ambient noise intensity detected by the sound sensor 303.

[0041] The adjustable light source module 2 is used to output light with adjustable brightness and color temperature based on the sleep aid mode or wake-up mode.

[0042] It should be noted that in the aforementioned intelligent sleep-aiding and wake-up lighting system:

[0043] Control Module 1: An embedded microprocessor (such as the STM32 series) is used as the main control module 1, which is responsible for data processing, logical judgment and instruction issuance.

[0044] Environmental perception module 3: Bio-radar 301: Employs a 60GHz millimeter-wave radar sensor (such as Infineon BGT60LTR11), placed at the head of the bed or above the ceiling, to detect the user's vital signs such as body movement, heart rate, and respiration.

[0045] Ambient light sensor 302: Employs a digital light intensity sensor (such as BH1750), installed near the bedside or other areas close to the sleeping area, to detect ambient light intensity in real time.

[0046] Sound sensor 303: Employs a digital microphone module (such as INMP441) to detect ambient noise intensity.

[0047] Adjustable light source module 2: It adopts RGBW four-color LED light group and is equipped with PWM dimming drive circuit, which can realize continuous adjustment of brightness and color temperature.

[0048] User interaction module 4: Optional touch screen, mobile APP or voice assistant (such as integrated Bluetooth / WIFI module) for user settings and status display, specifically allowing users to set their desired sleep time and wake-up time.

[0049] In this embodiment of the intelligent sleep-aid and wake-up lighting system, the bio-radar 301 monitors the user's vital signs in real time. Combined with ambient light and noise sensor information, the control module 1 can accurately determine whether the user is in the sleep preparation stage or awake state, and automatically trigger the sleep-aid mode or wake-up mode accordingly, achieving dynamic synchronization between the light and the user's sleep cycle. Furthermore, because the lighting system integrates data from multiple environmental sensors, the system will only activate the sleep-aid or wake-up program when the lighting is suitable, the noise is low, and the user's state meets the conditions, effectively preventing false triggering, improving usability in different sleep environments, and greatly enhancing the user's sleep and wake-up experience.

[0050] Furthermore, when the control module 1 activates the sleep aid mode, the adjustable light source module 2, according to a first preset program, smoothly and gradually changes the brightness and color temperature of the light from a first state to a second state within a first time period.

[0051] When the control module 1 activates the wake-up mode, the adjustable light source module 2, according to the second preset program, smoothly transitions the brightness and color temperature of the light from the second state to the first state within a first time period.

[0052] It should be noted that, through the above design, since the adjustable light source module 2 in this embodiment is equipped with a PWM dimming drive circuit, the brightness and color temperature can be continuously adjusted. Therefore, when the control module 1 turns on the sleep aid mode or wake-up mode, the brightness and color temperature of the light can be continuously changed between the first state and the second state. The entire light change state is soft and gentle, which is more conducive to the user entering a sleep state and reducing the light stimulation caused to the user when the wake-up mode is activated.

[0053] Specifically, the first state mentioned above is as follows:

[0054] The brightness range of the light emitted by the adjustable light source module 2 is 500lx-700lx, and the color temperature is cool, with a color temperature range of 4000K-5000K.

[0055] The second state mentioned above is specifically as follows:

[0056] The adjustable light source module 2 emits light with a brightness range of 10lx-50lx and a warm color temperature range of 1500K-2800K.

[0057] It should be noted that in the first state, the color temperature is cool, resulting in light that is approximately white; in the second state, the color temperature is warm, resulting in light that is approximately yellow.

[0058] In sleep aid mode, the adjustable light source module 2 controls the light to smoothly transition from high brightness and cool color temperature to low brightness and warm color temperature, which can effectively guide users into a relaxed state and help them fall asleep as soon as possible.

[0059] In wake-up mode, the adjustable light source module 2 controls the light to smoothly transition from low brightness and warm color temperature to high brightness and cool color temperature, simulating natural morning light, avoiding sudden light stimulation, and reducing the discomfort of waking up.

[0060] Furthermore, in this embodiment, the control module 1 is also used to dynamically adjust the execution parameters of the first preset program based on the user's vital signs information monitored by the bio-radar 301 during the first time period when the sleep aid mode is activated.

[0061] The steps described above for dynamically adjusting the execution parameters of the first preset program specifically include:

[0062] If, during the first time period, the bio-radar 301 determines that the user has not entered a static and relaxed state, the total duration of the first time period is extended, or the adjustable light source module 2 is controlled to output a brightness fluctuation mode.

[0063] It should be noted that when in sleep aid mode, since the bio-radar 301 detects that the user has not yet entered a static and relaxed state, the control module 1 will extend the total duration of the first time period so that the adjustable light source module 2 has more time to control the light to switch from the first state to the second state, thereby extending the sleep aid time for the user so that the user can fall asleep as soon as possible.

[0064] Alternatively, in another scenario, the adjustable light source module 2 can output a brightness fluctuation mode.

[0065] The light output by the adjustable light source module 2 fluctuates at a low frequency within the brightness range of 10lx-500lx, thereby producing a campfire-like effect and enhancing the sleep-aiding effect on the user, so as to help the user fall asleep faster.

[0066] Furthermore, in this embodiment, please refer to Table 1 below. The user vital signs information detected by the bio-radar 301 specifically includes the body movement index, heart rate index, and respiratory index.

[0067] In addition, Table 1 also records the detection range and trigger threshold of the bio-radar 301, ambient light sensor 302, and sound sensor 303 during actual operation, as shown in Table 1:

[0068] Table 1

[0069]

[0070] Furthermore, in this embodiment, when the bio-radar 301 detects that the user has entered a static and relaxed state (body movement index less than 10, heart rate between 60-80 beats / minute, respiratory rate between 12-18 breaths / minute, and lasting for at least 5 minutes) for more than a first time threshold, the ambient light intensity detected by the ambient light sensor 302 is lower than a first light threshold, the ambient noise detected by the sound sensor 303 is lower than a first sound threshold, and the sum of the values ​​of the first time threshold, the first light threshold, and the first sound threshold is less than a first preset comprehensive threshold, the control module 1 activates the sleep aid mode.

[0071] It should be noted that, based on Table 1 above, the first time threshold can be selected according to design requirements, and can be 3 min, 5 min, 10 min, etc.; the first illumination threshold can be selected according to actual requirements, and can be 100 lx, 90 lx, etc.; the first sound threshold can be selected according to actual requirements, and can be 40 dB, 30 dB, etc. Furthermore, the first preset comprehensive threshold can also be selected according to design requirements.

[0072] Furthermore, in this embodiment, when the bio-radar 301 detects that the user is in a light sleep period exceeding the second time threshold, the ambient light intensity detected by the ambient light sensor 302 is higher than the second light threshold, the ambient noise detected by the sound sensor 303 is higher than the second sound threshold, and the sum of the values ​​of the second time threshold, the second light threshold, and the second sound threshold is greater than the second preset comprehensive threshold, the control module 1 activates the wake-up mode.

[0073] It should be noted that, based on Table 1 above, the second time threshold can be selected according to actual requirements, and can be 3 min, 5 min, 10 min; the second illumination threshold can be 50 lx, 70 lx, etc.; the second sound threshold can be 40 dB, 50 dB, 60 dB, etc.; in addition, the first preset comprehensive threshold can also be selected according to design requirements.

[0074] The above provides a detailed description of the specific architecture and control mechanism of the intelligent sleep-aiding and wake-up lighting system provided in this embodiment. The following will further describe the intelligent sleep-aiding lighting device in a specific application scenario:

[0075] Scenario 1: Triggering and Execution of Sleep Aid Mode

[0076] Initial state: The user enters the bedroom at 10 pm, preparing to go to sleep.

[0077] Environmental perception module 3 starts working:

[0078] The BioRadar 301 detects that the user is lying down, the body movement index is gradually decreasing (e.g., from an activity value of >50 to <10), the heart rate is stable at 60-80 beats / minute, and the respiratory rate is 12-18 breaths / minute.

[0079] The ambient light sensor 302 detected an indoor light level of 300 lx (higher than the optimal level for sleep).

[0080] The sound sensor 303 detected an ambient noise level of 45 dB (such as the sound of a vehicle in the distance).

[0081] Module 1 judgment conditions:

[0082] The user remains in a static state for 5 minutes (first time threshold).

[0083] Illumination below 100 lx (first illumination threshold);

[0084] Noise level is below 40dB (first sound threshold).

[0085] If the overall score (such as the weighted sum) is lower than the first preset overall threshold, then the condition for sleep aid is determined.

[0086] Activate sleep aid mode:

[0087] The adjustable light source module 2 smoothly transitions the light from the initial state (brightness 600lx, color temperature 4500K) to the sleep-aid state (brightness 20lx, color temperature 2200K) within 30 minutes (the first time period) according to the first preset program.

[0088] Example of dynamic adjustment:

[0089] If the bio-radar 301 detects that the user's body movement index is still higher than 10 during the transition period (first time period), it determines that the user is not relaxed. The system will then automatically extend the transition time to 45 minutes or start a low-frequency brightness fluctuation mode (such as fluctuating once every 3 minutes between 500lx and 30lx) to help the user relax.

[0090] Scenario 2: Wake-up Mode Triggering and Execution

[0091] Morning wake-up phase: The user sets the wake-up time to 7:00.

[0092] Environmental sensing module 3 monitoring:

[0093] At 6:45, the BioRadar 301 detected that the user started to move (10 < body movement index < 30), the heart rate gradually increased, the breathing accelerated, and the user entered a light sleep period.

[0094] The ambient light sensor 302 detected that the outdoor natural light gradually increased (from 10 lx to 200 lx).

[0095] The sound sensor 303 detects that the alarm clock or ambient noise rises to 50dB or higher.

[0096] Decision conditions for control module 1:

[0097] The user is in a light sleep state for more than 3 minutes (second time threshold).

[0098] Illumination level above 50 lx (second illumination threshold);

[0099] Noise level is above 40 dB (second sound threshold).

[0100] If the overall score is higher than the second preset overall threshold, it is determined that the wake-up condition is met.

[0101] Enable wake-up mode:

[0102] The adjustable light source module 2, following the second preset program, smoothly transitions the light from low-brightness warm color (20lx, 2200K) to high-brightness cool color (500lx, 4500K) within 20 minutes, simulating the sunrise process and gently waking up the user.

[0103] In summary, the intelligent sleep-aiding and wake-up lighting system of this embodiment, through multi-sensor fusion and intelligent algorithms, achieves real-time perception of the user's sleep state and adaptive light adjustment, significantly improving sleep efficiency and wake-up comfort. The system possesses strong environmental adaptability and user personalization support, making it suitable for various scenarios such as homes, hotels, and senior living facilities.

[0104] The above provides a detailed description of the intelligent sleep-aiding and wake-up lighting system provided by the present invention. For those skilled in the art, based on the ideas of the embodiments of the present invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of the present invention.
