Description

Technical Field

[0001] The present invention belongs to the technical field of lighting regulation, and relates to a lighting dynamic regulation system device coordinated with biological rhythm, a method and an application. Background Art

[0002] Biological rhythm, also known as "biological clock". It is a periodic change process that occurs inside an organism. The most typical example is the periodic alternation of sleep and wakefulness. The reason why the alternation shows accurate rhythmicity is determined by the periodic changes in the functional state of body organs and cells on the one hand, and the influence of the environment on the other hand, such as the periodic changes in the rising and setting of the sun and the moon. The movement of the sun and the moon directly affects the rhythmic changes of organisms on the earth, such as the growth of grains with the seasons; migratory birds migrate with the changes in the tides (the tides are caused by the gravitational force of the moon on the ocean); the rhythmic rise and fall of human body temperature in a day and night, etc. The biological clock phenomenon makes people work at different times of the day. Sudden changes in the normal circadian rhythm (such as moving from the east to the west of the earth) will cause confusion in human body functions, irritability, and reduced work efficiency.

[0003] Studies have shown that when the brightness and color temperature of the light source increase or decrease, people can feel warm or cool, and the temperature inside the human body is also affected by the illumination and color temperature, which shows that the color temperature of the light source has a certain effect on the thermal regulation of the human body. Recently, people have chosen comfortable light sources based on the laws of psychological and physiological changes under different light source color temperatures, so that the human body can create the most suitable light environment for work and life in response to the changes in cold and warm seasons and ambient temperature. A famous discovery of the role of light sources in regulating biological rhythms and body temperature is that when the human body is exposed to high color temperature light sources at night, the body temperature rises, and this increase is only seen when the level of melatonin is high at night, but not when the level of melatonin is low during the day. This may be due to melatonin causing the regulation of light on human body temperature. Researchers have found the effect of night light sources on the core temperature of the human body, and believe that the decrease in the core temperature of the human body at night is related to melatonin and the hypothalamic thermal regulation center. In terms of human behavior, it is also shown that when the body temperature drops, people like relatively high ambient temperatures, and when the body temperature rises, they like relatively low ambient temperatures. These all suggest that the effect of light stimulation on thermal comfort is through the synthesis and release of melatonin. This shows that the color temperature of the light source plays an important role in the human circadian biorhythm and the adjustment of body temperature under different ambient temperatures, and there is a close relationship between the two.

[0004] CN1121880C discloses a portable light irradiation device for providing light stimulation to the user's eyes to adjust the biological rhythm and improve the awakening level, comprising a laterally elongated lighting unit for irradiating the user's eyes, a pair of pads suitable for wearing on the side of the user's head, a headband extending to the top of the user's head and engaging with the pads at its lower end, and a support arm extending from at least one pad and supporting the lighting unit at its front end and placing the lighting unit in front of the user's eyes. The support arm is slidably supported by the pad at its rear end so that the protruding length of the support arm relative to the pad is adjustable.

[0005] CN113170744A discloses a full-time monitoring device for the biorhythm phenotype of small animals based on chronobiology, comprising: a small animal test processing system device, which is used to feed the small animals to be tested separately and independently; a full-time automatic monitoring system device for the biorhythm phenotype, which is located below or around the small animal test processing system device to automatically monitor the independently fed small animals; an environmental factor control and monitoring system device, which is used to accommodate the small animal test processing system device and the full-time automatic monitoring system device for the biorhythm phenotype, as well as the temperature and humidity adjustment, temperature and humidity and light intensity monitoring in a closed space; an open source light source control system device is located on the top of the environmental factor control and monitoring system device to provide the required light source; a coaxial data acquisition and storage system device, which is used to receive the data obtained by the full-time automatic monitoring system device for the biorhythm phenotype and the environmental factor control and monitoring system device in real time and synchronously, and implement control according to requirements.

[0006] CN101589651 discloses a light source and a light irradiation device, which can effectively adjust the user's biorhythm without changing the color temperature of the irradiated light, the average color rendering index (Ra), or both. The light irradiation device includes: a blue light emitting body, which emits light with more energy in a wavelength region near the wavelength where M(λ) / z(λ) is the minimum value, and M(λ) is the relative sensitivity in the inhibition characteristics of melatonin secretion, and z(λ) is the relative sensitivity of the color matching function; a blue light emitting body, which emits light with more energy in a wavelength region different from the blue light emitting body; a red light emitting body; a green light emitting body; a diffusion plate, which diffuses the light from each light emitting body; a control device, which controls the luminous intensity of each light emitting body; an information input device, which inputs information related to the adjustment of the bio-effect degree of each light emitting body and information related to the color temperature of the lighting light; a switch, which switches the lighting of each light emitting body; and a storage device, which stores the luminous intensity of each light emitting body and the luminous intensity adjustment method.

[0007] However, the current existing technology only collects and analyzes data for outdoor environments or indoor environments, and is unable to achieve comprehensive data collection and integrated processing, resulting in an inability to achieve an ideal match between lighting adjustment and changes in human biorhythms, an inability to achieve rapid dynamic adjustment of lighting, and a lag in lighting adjustment. Therefore, there is an urgent need to redesign and improve the existing dynamic lighting adjustment scheme. Summary of the invention

[0039] In a second aspect, the present invention provides a method for dynamically adjusting lighting in coordination with biological rhythms, wherein the lighting dynamic adjustment system device described in the first aspect is used to dynamically adjust lighting, and the method for dynamically adjusting lighting comprises:

Optionally, through the wearer's body temperature, blood pressure, heart rate and blood oxygen saturation, combined with the current positioning information, time information, weather information, outdoor environment information and indoor environment information, the user's life state can be roughly divided into morning, work, nap, leisure, nighttime sleep and getting up at night. Each life state will correspond to an illumination parameter and a color temperature parameter to match the current user's life state, so that the user can get a better lighting experience in the current life state.

[0044] For example, during the working hours, relatively high color temperature and high illumination light is provided to awaken the brain excitement through strong light stimulation; then the indoor light environment simulates the changing law of natural light, the illumination slowly rises, the indoor color temperature changes with natural light on sunny days, and the color temperature remains high on cloudy days to give higher melatonin suppression, maintaining high work efficiency during the working hours; during the nap period, it is reduced to low color temperature and low illumination light to allow people to have a full rest; during the leisure period, high color temperature and high illumination light is provided again, and strong light stimulation is used again to awaken the brain excitement, and then the indoor light environment simulates the changing law of natural light, and the illumination slowly decreases until it is reduced to low color temperature and low illumination light during the night sleep period. This dynamic lighting adjustment method is consistent with the changing law of outdoor natural light, conforms to the human body's biological rhythm, and takes into account different weather conditions. It is not only conducive to regulating and improving people's emotions, but also can improve work efficiency.

[0045] In a third aspect, the present invention provides an application of the lighting dynamic adjustment system device described in the first aspect, wherein the lighting dynamic adjustment system device is used in homes, schools, shopping malls, offices or hospitals.
