Description
Technical Field
The utility model relates to the technical field of myopia prevention equipment, in particular to an outdoor illumination timer for preventing teenager myopia.
Background
In recent years, the myopia rate of teenagers in China is increased due to the influences of increasing the family learning time of primary and middle school students, reducing the frequency of outdoor activities, improving the use frequency of electronic products and the like and the superposition of adverse factors of new crown epidemic situations. The data of the national health committee show that as far as 2020, the total myopia rate of teenagers in China is 52.7%, wherein the myopia rate of kindergartens is 14.3%, the myopia rate of pupils is 35.6%, the myopia rate of junior and middle school students is 71.1%, and the myopia rate of senior and middle school students is 80.5%. From the perspective of myopia, 10% of myopic children are high myopia, and more than 30% are moderate myopia. In addition, according to the investigation of 9 provinces 14532 by the department of education in 2020, the myopia rates of students in half years increased by 11.7%, and the myopia rates of pupils, junior high school students increased by 15.2%, 8.2% and 3.8%, respectively, compared with those of 2019. Therefore, the situation of preventing the myopia from aging and growing is very severe in China.
Clinical studies have found that outdoor activity can reduce the incidence of myopia in teenagers, and the risk of myopia in teenagers is reduced by 2% for every 1 hour of outdoor activity per day. By exposing the juvenile cells to sunlight for 2 hours a day and more than 10 hours a week, the incidence of juvenile myopia can be reduced by more than 10%.
Enables teenagers to move in outdoor sunshine, and carries out photosynthesis through sunning, which is a simple, convenient and effective means for preventing myopia. In the last year, the national health commission disease control agency issues myopia prevention guidance during new coronary pneumonia epidemic of children and teenagers, which indicates that myopia can be effectively prevented from occurring and developing by fully contacting sunlight, and the teenagers are required to be subjected to outdoor activities under the condition of ensuring natural light for more than 2 hours every day. In 9 months at 2021, 15 departments such as education department also jointly issued "myopia prevention and control and photopic function work plans for children and teenagers (2021-2025), in which the students are definitely required to take the best to ensure the physical activity time of one hour each outside the school every day. However, it is a practical situation that the outdoor activity time of teenagers hardly reaches 2 hours per day. In 29/8/2020, the '2020 China teenager myopia prevention and control big data report' issued by the people network public opinion data center and the university of China shows that in 1 to 7/2020, the average daily outdoor effective exposure time of the teenagers is only 32.3 minutes and does not reach 1/3 of a recommended value, so that the risk of myopia development of children is greatly increased, the fastest myopia development stage is 8 to 14 years, and the myopia is probably one of the main reasons for the rapid myopia rate increase of students in half a year.
In order to prevent myopia of teenagers, children need to be guaranteed 2 hours of outdoor activity time each day, which has been accepted and appreciated by all parties, but how to really implement, the common efforts of schools, parents and children are also needed. At present, no real-time data is available, which reports the time length of the children which have been active in natural light on the day, and myopia is often caused in subtlety, so that under the pressure of the burden of the courseware, the children are often difficult to ensure sufficient 'photosynthesis' time.

Spectral difference between sunlight and artificial light
The sunlight in nature is emitted in the process of solar nuclear fusion and the like and is formed by mixing various monochromatic lights. Since the utility model of Edison bulb in 1879, various artificial light sources have been developed with the advancement of technology. Incandescent lamps and halogen tungsten lamps are light produced by tungsten filament which is energized to generate heat and high temperature, fluorescent lamps are cold light emitted by fluorescent powder excited by rays, LEDs are the most mainstream artificial light at present, and electricity is directly converted into light by a semiconductor wafer. The above various artificial lights all use a near-solar light source as an ultimate goal, in order to generate white light, the artificial light source respectively generates red, green and blue tricolor lights and then synthesizes white light, so the spectrum has very obvious difference with the sunlight, see fig. 1, fig. 1 is a chromaticity diagram for measuring the difference between the artificial light and the sunlight, three vertexes of a triangle are extreme values of the red, green and blue light source respectively, the area of the triangle represents the color range covered by the light source, and according to the National Television Standards Committee (National Television Standards Committee), the larger the area of the triangle is, the higher the percentage of the color range is.
The visible light spectrum of human eyes has a wavelength range of 380 nm-760 nm, can sense seven colors of red, orange, yellow, green, cyan, blue and purple, but can not directly distinguish artificial light from sunlight. Artificial light and sunlight can be effectively distinguished through spectral analysis, and as seen from fig. 2, the sunlight is a continuous spectrum which comprises the whole visible light spectrum section, while the spectrum of the white light LED is discontinuous and is only in the wavelength section of 430-680 nm; another important spectral feature is that the blue light of sunlight is low green and high, while the spectral feature of white LEDs is the reverse, blue light is high green and low.
The utility model uses the difference points of the sunlight and the artificial light as the characteristic value to judge whether the sunlight exists.
The main mechanism of sunlight for preventing myopia of teenagers is as follows:
myopia is divided into refractive myopia and axial myopia, and clinical data indicate that most of them are axial myopia, i.e. the increase in length of the axis of the eye is the primary cause of myopia. Experimental research also proves that two reasons for preventing myopia by solar illumination exist, namely, under strong light illumination, pupil contraction makes depth of field deeper, blur is reduced, and myopia is inhibited; secondly, in sunlight, the illumination stimulation of a specific frequency band is beneficial to the synthesis of retina and the release of dopamine, and the increase of the axis of the eye can be delayed, so that the myopia can be prevented and treated.
Based on the above principle, the myopia prevention of teenagers is realized through solar illumination, and the following 3 key factors are required to be met:
1. ultraviolet rays with a wavelength ranging from 315nm to 400nm can inhibit the growth of the axis of the eye;
