[0020] In order to further illustrate the technical means and effects adopted by the present application to achieve the predetermined object of the present application, the specific embodiments, structures, features and effects thereof according to the present application are described in detail below in combination with the drawings and preferred embodiments.
[0021] Embodiment one: Anti-sensitivity application of the system in the scene of the elderly getting up at night.
[0022] Lighting parameter and demand definition module: In combination with the characteristics that the visual function of the elderly deteriorates with age, the tolerance of the pupil to light stimulation at night is greatly reduced, and walking safety needs to be ensured in dim light when getting up at night, and the functional attributes of the bedroom as a resting and getting-up space, the core lighting parameters and adjustment demands in this scene are determined, wherein the bedroom night light illumination area illuminance is strictly set to ≤50 lux, which can provide the elderly with basic light to clearly identify the bed edge and ground obstacles, and can also avoid strong light direct radiation to cause pupil contraction, reduce eye discomfort and temporary blurred vision; the color temperature corresponding to the getting-up mode is determined as 1900±100K, the warm light in this color temperature interval is more in line with the night visual adaptation habit of the elderly, which can reduce the interference of light on the secretion of melatonin and reduce the difficulty of falling asleep again after getting up at night; in view of the high-frequency behavior of the elderly getting up at night, the lighting adjustment demand is set as “fast response + gradual light-up” at the same time, to ensure that the lighting starts in time when the elderly get up, and at the same time, through the way of gradually brightening the light, the eyes have sufficient time to adapt to the change of light, avoiding the problems of dizziness and blurred vision caused by sudden light-up, and ensuring the visual safety and comfort during the process of getting up at night, as shown in Figure 1 .
[0023] Zero-blue-light layered lighting hardware construction module: A pure LED lighting source is composed of a silicon-based yellow light LED and a silicon-based red light LED, wherein the silicon-based yellow light LED has a peak wavelength accurately controlled at 585-590 nm, the silicon-based red light LED has a peak wavelength stably at 625-630 nm, and the two are packaged in a ratio of 3:1. Through multi-primary color chip light mixing technology, the blue light component in the light source is completely eliminated, realizing zero blue light output, avoiding potential damage of blue light to the macular area of the retina of the elderly from the source, especially suitable for the more fragile physiological state of the eyes at night. In the bedroom space, a layered lighting structure is formed by configuring main lights, auxiliary lights and key lighting lamps. The main light is a ceiling light with a thickness of less than 5 cm, and the waterproof panel has a protection level of ≥IP65, which can effectively resist the humid water vapor that may occur in the bedroom environment (such as condensation water generated by window ventilation in winter), prolong the service life of the lamp and ensure the safety of electricity. The auxiliary light is a wall lamp with diffuse reflection light material, and the anti-glare value UGR is ≤16, which can evenly disperse the light into the space, avoid the strong light spots formed by the direct light of the lamp, and prevent the elderly from feeling dazzling when their eyesight contacts the lamp. The key lighting lamps (such as reading lamps) are not used in the night scene, and the connection interface with the intelligent control integrated module is reserved, providing hardware support for data transmission and function cooperation between modules, ensuring the stability and continuity of the whole lighting system.
[0024] Intelligent control integrated module: Integrating four core sensing components—millimeter-wave radar, infrared sensor, digital light sensor, and low-power camera—each component's function is deeply adapted to the bedroom nighttime getting-up scenario: The millimeter-wave radar has a detection range of 0.5m-8m, a detection angle of up to 120°, and a resolution accurate to 0.1m. It can collect real-time data on the elderly person's presence in the bedroom (e.g., whether they are in bed or have gotten up), their distance from the radar (to determine their relative position to the bedside or doorway), and their movement speed (to identify the pace of their nighttime getting-up movements), providing precise human dynamic data support for lighting adjustment; the infrared sensor has a detection range of 1m-5m, a detection angle of 90°, and a response time ≤0.5 seconds. It can quickly capture the intensity of human infrared radiation signals (distinguishing between humans and inanimate objects such as furniture and clothing) and activity trigger signals (sensing the initial moment of the elderly person getting up), ensuring that the lighting starts immediately upon the nighttime getting-up behavior, preventing the elderly person from groping in the dark; the digital light sensor's measurement range covers… With a range of 0-20000 lux, accuracy controlled within ±5%, and a response time ≤100ms, it can acquire real-time indoor and outdoor illuminance values and differences (to determine whether outdoor moonlight or streetlights interfere with indoor lighting at night), providing accurate ambient light data for adjusting auxiliary lighting. The low-power camera has a resolution of 1080P and a frame rate of 15fps, which can clearly capture human contour images (confirming that the active object is an elderly person and not a pet), behavioral action sequence frames (completely recording the entire process from getting up, getting out of bed to walking to the door), and location coordinates (precisely locating the elderly person's specific position in the bedroom), further improving the accuracy and reliability of the sensing data. Each sensing component is connected to the lighting system through a dedicated interface, and integrates multi-scene color temperature and illuminance switching, voice control, timed on / off, and gradual brightening / darkening functions. In the scenario of getting up at night, the transition time and brightness change range of the gradual brightening / darkening function are optimized to match the elderly person's nighttime visual adaptation rhythm and avoid discomfort caused by abrupt changes in light.
[0025] Adaptive lighting adjustment module: Each sensor collects real-time data on human movement, ambient light intensity, and behavioral images and transmits it to the module core. First, combining the multi-source sensing fusion weight dynamic allocation algorithm, it comprehensively considers human recognition reliability (confirming the current active object is an elderly person and is awake), ambient light intensity influencing factors (determining whether there are other interfering lights indoors at night), and behavioral recognition matching degree (confirming the current action is getting up at night rather than turning over or adjusting sleeping posture), to calculate the fusion decision weight at time t. The calculation formula for the multi-source sensing fusion weight dynamic allocation algorithm is as follows: ,in: for Integrate decision-making weights at all times. To enhance the credibility of human body recognition, Ambient light intensity is an influencing factor. For behavior recognition matching degree, The weighting coefficients representing the reliability of human body recognition. This represents the weighting coefficient of the ambient light intensity influencing factor. The weight coefficients represent the matching degree of behavior recognition, and This serves as the core basis for determining whether to turn off the main light and adjust the illuminance of the auxiliary light. When an elderly person gets out of bed to get up at night, the sensor detects continuous and stable human activity signals. If the fusion decision weight calculated by the algorithm is not less than the main light-off threshold of 0.2, the main light remains off to avoid the sudden bright light from disrupting nighttime visual inertia. Subsequently, using the auxiliary light target illuminance adjustment algorithm, combined with real-time ambient light intensity data collected by the digital light sensor, the target illuminance value that the auxiliary light should be adjusted to is accurately calculated. The calculation formula for the auxiliary light target illuminance adjustment algorithm is as follows: ,in To supplement the basic illuminance of the auxiliary lamps, To adjust the coefficient, and thus adjust the illuminance of the auxiliary lights, Indicates the target illuminance of the auxiliary lights. for The system integrates decision-making weights at all times to ensure that the auxiliary light illumination remains stable within the range of ≤50 lux, which meets the basic needs of identifying obstacles when getting up at night without causing excessive light.
[0026] Next, based on the behavior-related adaptive illuminance adjustment algorithm, and considering the changes in location during the elderly person's nighttime awakening process (such as walking from the bedside to the wardrobe, or from the wardrobe to the door), the calculation formula for the behavior-related adaptive illuminance adjustment algorithm is as follows: ,in: for Spectral distribution of light source at any time Indicates the wavelength of light. Represents a time variable. This is the standard spectrum of silicon-based red LEDs. This is the standard spectrum for silicon-based yellow LEDs. This represents the weighting coefficient of the silicon-based yellow LED at time t. This represents the weighting coefficient of the silicon-based red LED at time t, which dynamically adjusts the illuminance output of the auxiliary light to ensure that the elderly can obtain uniform and suitable lighting in different areas of the bedroom, avoiding excessively dim or bright light due to differences in location.
[0027] Meanwhile, based on the color temperature-scene-time linkage adjustment algorithm, combined with the attributes of the nighttime scene, the current nighttime period (such as the difference in visual sensitivity between 2 AM and 5 AM), and related parameters, the calculation formula for the color temperature-scene-time linkage adjustment algorithm is as follows: ,in: For behavior The corresponding target illuminance, a base illuminance defined in the lighting parameter and demand defining module for the behavior b set, a fusion weight influence coefficient, a distance of the elderly person from the lighting area, a decay coefficient, denotes an inverse function, is The moment fusion decision weight, maintain 1900±100K soft color temperature, through slow and continuous color temperature adjustment mode, realize color temperature smooth dynamic change, prevent color temperature mutation cause eye fatigue.
[0028] And, real-time correlation zero blue spectrum real-time regulation algorithm, continuous monitoring of the spectral distribution of the light source, zero blue spectrum real-time regulation algorithm calculation formula is: , wherein: is The moment actual color temperature, is the scene base color temperature, is the scene allowed fluctuation range, is the scene start time, is the scene end time, is The moment fusion decision weight, denotes a time variable, once the presence of trace blue light component in the spectrum is detected, immediately adjust the light emitting proportion of silicon-based yellow light LED and silicon-based red light LED, ensure that always maintain zero blue light output in the whole night process, fundamentally reduce the stimulation of light to the sensitive eyes of the elderly at night.
[0029] Verification and adaptation module: The complete system after adaptive adjustment is applied to the real elderly bedroom night getting up scene, and a 15-day actual use test is conducted on the elderly population of 60-85 years old, covering different visual degradation degrees such as mild presbyopia and moderate postoperative cataract. The verification link focuses on three aspects: first, the parameters set by the lighting parameter and demand definition module are quantitatively detected. The illuminance of the night light in different areas of the bedroom (bedside, doorway, corridor) is measured multiple times by a professional illuminometer to ensure that it is stable ≤50 lux. The color temperature value under the night getting up mode is continuously monitored by a color temperature instrument to ensure that it is accurately maintained at 1900±100K; second, the hardware performance of the zero-blue light layered lighting hardware construction module is detected. The anti-glare effect of the auxiliary light is evaluated by subjective feedback from the elderly (whether there are feedbacks such as dazzling and eye acidification is recorded). The light source output is monitored by a spectrometer throughout the process to confirm that the zero-blue light state is stable. At the same time, the main light and auxiliary light are continuously operated for 72 hours to observe whether there are faults such as flickering and sudden brightness changes; third, the control function of the intelligent control integrated module is tested. The response time from the elderly getting up action to the start of the auxiliary light is recorded (the requirement is ≤1 second). The transition effect of the gradual brightening and dimming function is observed (to ensure that there is no obvious stuttering in the process from dark to light). The data coordination of components such as millimeter wave radar and infrared sensor is checked (to avoid abnormal situations such as "the sensor detects a human body but the lighting does not start"). According to the feedback from the elderly during the test, if some of the elderly reflect that the light is still slightly dazzling, the basic illuminance of the auxiliary light is adjusted to 45 lux. If there is a situation that the color temperature is slightly high in the early morning period, the time correlation parameter in the color temperature-scene-time linkage adjustment algorithm is adjusted. Finally, a personalized lighting solution that adapts to different visual states of the elderly and can stably meet the anti-sensitive needs of the bedroom night getting up is formed, ensuring that every elderly person can have a safe, comfortable and non-stimulating lighting experience during the night getting up process.
[0030] In summary, the embodiment focuses on the anti-sensitive scene of the elderly in the bedroom at night, and shows the complete operation process of the indoor zero-blue light healthy lighting system. Each module works together. The lighting parameter and demand definition module sets parameters according to the visual characteristics of the elderly at night. The zero-blue light hardware construction module avoids blue light stimulation from the source. The intelligent control integrated module accurately perceives through multiple sensors. The adaptive lighting adjustment module realizes dynamic adaptation of lighting through multiple algorithms. The verification and adaptation module optimizes the scheme through testing. The whole system from parameter setting to hardware construction, intelligent control and verification and adaptation, fully guarantees the visual comfort and safety of the elderly during the night getting up, and fully reflects the adaptability of the system in the elderly care scene.
[0031] Embodiment two: Application of the method in the elderly bathroom washing scene.
[0032] S100, parameter and demand determination: In combination with the fact that the elderly have lens opacity, decreased sensitivity of retinal photoreceptor cells, and the need to clearly distinguish facial details (such as facial hair and makeup residue) while being unable to withstand strong light stimulation, and the fact that the bathroom is used as a space for washing and grooming, the core parameters and adjustment directions of each dimension are determined, and the illuminance of the bathroom mirror area is set to be ≥ 350 lux. This value can ensure that the light is evenly distributed over each area of the face, avoiding insufficient illumination that causes the elderly to be unable to see the fine dirt on their face or the location of their washing supplies. Washing behavior is a type of life activity, and the corresponding color temperature is determined to be 4000K. At this color temperature, the color reproduction of objects is closer to the natural state, which can help the elderly accurately identify the true colors of washing supplies such as toothpaste and facial cleanser, reducing the likelihood of mistakenly grabbing the wrong item due to color deviation. The color rendering index is required to be Ra≥92, which can clearly present the changes in facial skin color, making it easier for the elderly to observe their skin condition (such as whether there is redness, swelling, or wounds). In addition, in response to the actions that the elderly may take during the washing process, such as leaning towards the mirror, bending down to get water, and lifting their hands to wash their face, the lighting adjustment requirements are set to be "dynamic illumination adaptation + stable color temperature", ensuring that the lighting always meets the visual needs during different actions, avoiding issues such as reduced washing efficiency or eye discomfort caused by light problems, as shown in FIG. 8. Figure 2
[0033] S200, zero-blue hardware construction: A pure LED lighting source is adopted, which is composed of a silicon-based yellow light LED and a silicon-based red light LED. The peak wavelength of the silicon-based yellow light LED is precisely controlled at 585-590 nm, and the peak wavelength of the silicon-based red light LED is stably at 625-630 nm. The two are packaged in a ratio of 3:1, and the blue light component in the light source is completely filtered through multi-primary color chip light mixing technology, achieving zero-blue output. This avoids chronic damage to the elderly's macular area of the retina caused by blue light from the source, especially in the humid environment of the bathroom, where the eyes are more susceptible to irritation. In the bathroom space, a layered lighting structure of "main light + auxiliary light + key lighting" is constructed. The main light is a ceiling light with a thickness of ≤5 cm, and its waterproof panel has a protection level of ≥IP65, which can effectively resist water vapor erosion during washing, prevent short circuits caused by moisture in the lamp interior, prolong the service life, and ensure electrical safety. The auxiliary light is installed on both sides of the mirror and uses a diffuse reflection light material with a glare value of UGR≤16, which can softly project light onto the face, avoiding the formation of reflected light spots on the mirror caused by direct light from the lamp, and preventing the elderly from experiencing eye strain when looking at the mirror. The key lighting lamp is a model with a 360° rotating lamp head and a 180° flipping function, with a maximum opening degree of the clamp of ≥5 cm, which can be flexibly clamped on the edge of the washbasin or the mirror cabinet. It provides supplementary lighting for local operations such as toothpaste squeezing and razor use, meeting the needs of detailed washing. At the same time, the adaptation ports for the intelligent control module are reserved at the interfaces of each lamp, laying a hardware channel for subsequent sensing data transmission and intelligent lighting adjustment, ensuring that each lamp responds cooperatively.
[0034] S300, intelligent control integration: Integrate four types of sensing components: millimeter wave radar, infrared sensor, digital light sensor, and low-power camera. Each component is deeply matched with the bathroom washing scene: millimeter wave radar detects a distance of 0.5m-8m, an angle of 120°, and a resolution of 0.1m, which can collect the position coordinates of the elderly in the bathroom (such as whether they are close to the mirror or the distance from the washbasin), movement speed (to determine whether they are washing slowly or quickly taking water), and provide dynamic human position data for lighting adjustment; infrared sensor detects a distance of 1m-5m, an angle of 90°, and a response time of ≤0.5 seconds, which can quickly capture the intensity of human infrared radiation signals (distinguish between humans and towels, shelves, and other items in the bathroom) and activity trigger signals (sense the elderly entering the bathroom and starting to wash), ensuring that the lighting is turned on in time when the elderly enter the scene, avoiding groping in the dark; digital light sensor measures a range of 0-20000 lux with an accuracy of ±5% and a response time of ≤100ms, which can obtain real-time illumination values in the bathroom (such as the brightness of natural light through the window during the day), outdoor real-time illumination values, and the difference between the two, providing environmental light as a basis for determining whether additional lighting is needed; low-power camera with a resolution of 1080P and a frame rate of 15fps can clearly capture human behavior sequences (such as the complete action of washing face with hands or bending down to get water) and human contour images (confirming that the moving object is an elderly person), further improving the accuracy of behavior recognition. Connect each sensing component to the lighting system through a dedicated data interface, while integrating multi-scene color temperature and illumination switching, voice control, timing switch, and gradual brightening and dimming functions. The voice control function can support the elderly to adjust the lighting through voice commands such as "brighten the mirror light" and "lower the color temperature" when their hands are wet or they are holding washing supplies, improving the convenience of use; the gradual brightening and dimming function can avoid the impact on the eyes caused by sudden turning on or off of the lighting.
[0035] S400, adaptive lighting adjustment: Each sensor collects human position, behavior, and environmental light data in real time and transmits them to the adjustment core. First, combine the multi-source sensing fusion weight dynamic allocation algorithm, integrate human recognition reliability (confirm that the current moving object is an elderly person and is in a washing state, not just passing by), environmental light intensity influence factor (such as insufficient illumination in the bathroom on a cloudy day, which requires increased lighting compensation), and behavior recognition matching degree (determine whether the current action belongs to the washing process or not), calculate the fusion decision weight at time t, and the calculation formula of the multi-source sensing fusion weight dynamic allocation algorithm is: Use this as the core basis for lighting adjustment. When the elderly approach the mirror to start washing, this algorithm determines that the main light does not need to be turned off, and the auxiliary light target illumination adjustment algorithm is used. The calculation formula of the auxiliary light target illumination adjustment algorithm is: , combined with the real-time ambient light intensity data collected by the digital light sensor, the target illuminance value that the auxiliary lamp should reach is accurately calculated, ensuring that the illuminance in the mirror area is stable at ≥350 lux, and the light is evenly covered on the face.
[0036] Then, according to the behavior-related illuminance adaptive adjustment algorithm, according to the change of the old people's washing action (such as bending down to get water, the head is close to the washstand, the lower lighting needs to be appropriately reduced to avoid being too bright; when washing face, the face is far away from the mirror, the angle of the mirror light needs to be adjusted to enhance the light coverage), the calculation formula of the behavior-related illuminance adaptive adjustment algorithm is: , dynamically adjust the illuminance output of the corresponding lamps, and ensure that the lighting in each action stage meets the visual needs.
[0037] At the same time, according to the color temperature-scene-time linkage adjustment algorithm, combined with the washing scene attribute, the current period (such as the morning washing needs clear light, the evening washing needs slightly soft light) and the distance between the old people and the lighting area, the calculation formula of the color temperature-scene-time linkage adjustment algorithm is: , maintain a stable color temperature of 4000K, and avoid visual fatigue caused by color temperature fluctuations through subtle color temperature smoothing adjustment.
[0038] And the real-time correlation zero-blue spectrum real-time regulation algorithm, the calculation formula of the zero-blue spectrum real-time regulation algorithm is: , continuously monitor the spectral distribution of the light source, and once a trace of blue light component is detected in the spectrum, immediately adjust the light-emitting ratio of the silicon-based yellow light LED and the silicon-based red light LED, to ensure that the zero-blue light output is maintained throughout the washing process, and reduce the stimulation of light to the eyes.
[0039] S500, scene verification and adaptation: The adaptive lighting system is applied to a real bathroom washing scene of the elderly. A group of 60-80 year old elderly people with different eye conditions such as mild presbyopia and dry eye are selected for a 10-day actual use test. The verification link focuses on three aspects: first, the lighting parameters and the standards set in the demand determination stage are tested. The illuminance is measured multiple times at different positions (forehead, chin, cheek) in front of the mirror by a professional illuminometer to ensure that it is ≥ 350 lux. The color temperature value during washing is continuously monitored by a color temperature instrument to ensure that it is stable at 4000K. The color rendering index is verified by a color restoration test card to ensure that the color of the items does not deviate significantly, the second is to test the performance of the zero-blue hardware construction. The anti-glare effect of the auxiliary lamp is evaluated by subjective feedback from the elderly (whether eye dryness, stinging and other discomforts occur are recorded), the light source output is monitored by a spectrometer throughout the process to confirm the stability of the zero-blue state. At the same time, the flexibility of the key lighting lamps is tested to check whether the lamp head rotation and clamp fixing effect meet the fine use requirements, the third is to test the intelligent control integration function. The response time from the elderly entering the bathroom to the lighting starting is recorded (the requirement is ≤ 1 second), the recognition accuracy of the voice control command is observed (such as whether the "brighten the mirror light" command can be accurately executed), the sensor data coordination is checked (to avoid abnormal situations such as "the sensor detects the lifting action but the lighting is not adjusted"), according to the test feedback, if some elderly people reflect that there is slight glare in front of the mirror, the installation angle of the auxiliary lamp is adjusted and a soft light cover is added; if the elderly feel that the light is too strong when washing in the evening, the time period associated parameters are optimized through the color temperature-scene-time linkage adjustment algorithm, finally forming a personalized lighting solution that adapts to different eye conditions of the elderly and can stably meet the bathroom washing needs, ensuring that the elderly can complete the washing in a safe and comfortable lighting environment.
[0040] In summary, this embodiment relies on the bathroom washing scene of the elderly, presents the specific application of indoor zero-blue healthy lighting method, from the parameters and demand determination to meet the washing visual demand, to the zero-blue hardware construction to create adaptive light source and lamp structure, to the intelligent control integration to realize multi-component linkage, then through the adaptive lighting adjustment algorithm to accurately adapt the lighting, finally through the scene verification and adaptation optimization scheme, the method is closely linked at each step, which not only ensures sufficient lighting and true color during washing, but also avoids blue light damage, and also considers the operation convenience, effectively meets the lighting needs of the elderly in the washing scene, and highlights the practicality and pertinence of the method.
