But the non-drug treatment is a method with high safety and symptom relief, and related researches are carried out. Among them, phototherapy is considered as a therapeutic method for both sleep disorders and depression, and is not prone to serious side effects.
Intrinsic photosensitive retinal ganglion cells (ipRGCs) use the photochromic visual melanin to deliver optical stimuli to different areas of the brain through the hypothalamic tract, primarily to our internal "master clock", the upper nucleus of the visual junction, which in turn controls the rhythm and regulates sleep.
The apparent melanin is very sensitive to short wavelength light, i.e., blue light, which makes these wavelengths of light efficient time service factors. Due to the influence of artificial light, the natural illumination time of modern people is reduced, especially the illumination exposure in daytime is insufficient, the artificial illumination exposure in night is increased, the work and rest rhythm of a human body is not considered by the conventional illumination lamp on the market, the human circadian rhythm system is greatly influenced by an illumination system, and sleep disorder and depression are easily caused.
Therefore, a rhythm lamp for treating insomnia appears in the market, but the main change of the rhythm lamp is color temperature, but the change of pure color temperature does not correspond to the change of spectrum and brightness, so that the final sleep adjusting effect cannot simulate the change effect of sunlight, and the sleep improving effect is poor; the existing rhythm lamp needs to be adjusted manually and actively, but the effect after adjustment is poor due to the fact that a user lacks necessary knowledge, or the rhythm lamp is adjusted by utilizing a solidified illumination parameter change curve, so that the requirement of different people is difficult to adapt.
Therefore, it is necessary to study the dynamic parameter adjustment of the rhythm lamp and improve the therapeutic effect of the rhythm lamp.

Detailed Description
The following detailed description of embodiments of the invention is exemplary and intended to be illustrative of the invention and not to be construed as limiting the invention.
In this embodiment, a system capable of dynamically adjusting biorhythm light is provided, including: rhythm light, sleep parameter acquisition system, control system.
The rhythm light can adjust spectrum, color temperature and brightness according to the control signal. In particular, the rhythm lamp comprises a power supply interface, a color temperature driver, a spectral driver, a brightness driver, and a light source. The power supply interface is connected with external alternating current and is used for providing power for the color temperature driver, the spectrum driver, the brightness driver and the light source. The color temperature driver, the spectrum driver and the brightness driver output corresponding color temperature, spectrum and brightness driving signals to the light source according to the control signals. The light source is used as the final output of the lamp and emits light with corresponding color temperature, spectrum and brightness.
The sleep parameter acquisition system can acquire sleep parameters of a user. Specifically, the sleep parameter acquisition system is used for actively recording the input subjective or other sleep monitoring results of a sleep diary through intelligent equipment, such as a smart watch, and the acquired sleep parameters comprise: the user gets up time, falls asleep time, wakes up time after falling asleep, and wakes up time. Of course, the sleep parameters can be collected by combining a plurality of devices and subjective records, for example, the getting-up time and the getting-up time can be collected by actively recording the getting-up time and the getting-up time of a user, or the getting-up time and the getting-up time of the user can be collected by turning off and on a rhythm lamp and the like, and the sleeping time, the waking time and the waking time of the user after sleeping can be collected by using the intelligent watch.
The control system is internally provided with an algorithm module for adjusting the illumination data curve according to the sleeping parameters of the user, and is also provided with a storage module for storing a plurality of basic illumination data curves of different urban areas and a personalized illumination change control curve of the user; and can generate control signals according to the illumination change control curve to adjust the spectrum, color temperature and brightness of the output of the rhythm lamp.
The basic illumination data curves of different urban areas are obtained through the following processes:
step 1.1: in a selected urban area, the area is prevented from being influenced by external illumination, a sunny day between a small full season and a miscanthus season is specifically selected in a spring and summer intersecting season, a spectrometer is adopted to collect natural light spectrum, color temperature and brightness at a position which is 1m away from a window horizontally and 1.2m vertically indoors under a sunny condition, the natural light spectrum, the color temperature and the brightness are continuously collected for a plurality of days, 24 hours are daily, and the natural light spectrum, the color temperature and the brightness are automatically collected every half an hour at intervals;
step 1.2: and performing outlier removal and missing value addition processing on the acquired data to obtain a basic illumination data curve of the selected city.
Therefore, the storage module stores basic illumination data curves of different urban areas, and when the user uses the basic illumination data curves, the city closest to the time zone can be selected as a basic starting value according to the area.
After the basic illumination data curve of the selected urban area is obtained, the rhythm illumination change control curve is correspondingly adjusted according to the acquired sleep parameters of the user, and the personalized illumination change control curve for the specific user is obtained. As previously described, the acquired sleep parameters include: the user gets on the bed, gets off, falls asleep, wakes up after falling asleep; here we get the average time to get up for the user by multiple acquisitions. And then, setting the average getting-up time of the user as the getting-up time, taking the getting-up time as the inflection point of the night relative platform period and the rising period, adjusting the illumination change control curve from the getting-up time, wherein the color temperature is linearly increased, the brightness is linearly increased, the spectrum is correspondingly changed until the daytime relative platform period reaches the maximum value of the color temperature and the brightness parameters of the lamp, the period is maintained for 6 hours, the falling period is entered, the color temperature is linearly reduced, the brightness is linearly reduced, the spectrum is correspondingly changed until the night user gets on the bed, and the night relative platform period is taken as the inflection point of the falling period and the night relative platform period, so that the color temperature and the brightness of the rhythm lamp are reduced to the minimum limit value.
In addition, to better improve the sleep quality of the user, we also calculate the sleep efficiency by the formula sleep efficiency= (wake-up time-fall wake-up time)/(get-up time-get-in time) ×100% according to the acquired sleep parameters, and correct the user get-in time according to the sleep efficiency:
if the sleeping efficiency of the user is above 85%, the current set time for getting on the bed of the user is set as the time for getting on the bed of the user used when the personalized illumination change control curve is calculated. If the sleeping efficiency of the user is less than 85%, the current set getting-up time of the user is taken as the getting-into time, but the getting-up time is required to be ensured to be at least 6 hours away from the average getting-up time of the user, and if the sleeping efficiency of the user is less than 6 hours, the getting-up time is determined as the getting-up time according to the 6 hours before the average getting-up time of the user.
Therefore, the adjusted personalized illumination change control curve of the user is utilized for illumination, and the sleeping quality of the user can be better improved.
In addition, a man-machine interaction system realized by a mobile phone APP is designed, and information interaction is carried out between the man-machine interaction system and a control system; for example, through a man-machine interaction system, a user can select a region where the user is located, and the rhythm lamp can be controlled to turn on or off a rhythm function.
Although embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and not to be construed as limiting the invention, and that variations, modifications, alternatives, and variations may be made in the above embodiments by those skilled in the art without departing from the spirit and principles of the invention.
