Description

Background brightness self-adaptation eye-protecting lamp system

Technical Field

The invention relates to the field of eye-protection lamps, in particular to a background brightness self-adaptive eye-protection lamp system. The light that user's eyes received remains throughout at suitable intensity, and suitable light slows down user's eyes's fatigue degree to adjust light according to the time length reasonable in order to improve user's learning efficiency of user's study.

Background

In a dark environment (with luminance lower than 10-cd/m), at night without light illumination, the cone cells of the human eyes lose sensitization, the visual function is replaced by the rod cells, the human eyes lose the ability to perceive color, and only white and gray can be distinguished; in a darker environment (with luminance between 10-cd/m and 10 cd/m), the cone cells and rods cells of the human eyes have functioned simultaneously; in a bright environment (when the brightness is higher than 10 cd/m), the cone cells of the human eyes are active, the rod cells lose sensitization, for the human eyes, ambient light is light entering the human eyes from a front view angle, and light rays in other directions have no effect on the feeling of the human eyes no matter the intensity of the light rays; under the different condition of ambient brightness, in order to make the user can obtain a good use experience, need different adjustment methods, especially under the low condition of luminance, need carry out the light filling to ambient light.

The education department issues implementation schemes (solicited opinions) about comprehensive prevention and control of myopia of children and teenagers, the scheme requirements are that by 2030, the myopia rate of the children and teenagers in China is obviously reduced, the overall level of the eyesight health of the children and the teenagers is obviously improved, the myopia rate of the children at the age of 6 is controlled to be about 3%, and the myopia rate of pupils is reduced to be below 38%. Meanwhile, the myopia prevention and control work, the total myopia rate and the physical health conditions of the children and the teenagers are brought into government performance assessment indexes, local governments and schools with continuously three-year decline of the physical health level of the children and the teenagers are blamed according to laws, and the current practical situation is as follows:

1. according to the research and development of the national students on the physique health, the vision conditions of the students in China are not optimistic, and the vision defect rates of pupils at 7-12 years old, junior students at 13-15 years old and senior students at 16-18 years old are respectively 40.89%, 67.33% and 79.20%. The myopia prevention and treatment center reports that the myopia of teenagers in a certain direct prefecture city is higher than 9-13 years old at present, and is characterized by low age and high degree, the degree of the myopia is higher than 600, retinopathy is easy to cause, according to the notification requirement of the education department on the printed ' general high school student physical examination work guidance suggestion ', any naked eye vision is lower than 5.0, and related professionals cannot take the myopia, so that the myopia prevention work cannot be carried out slowly, ' poor visual environment, insufficient light during reading and writing, overlong short-distance eye use time, incorrect reading and writing posture and the like are important reasons for the occurrence or development of myopia.

2. The LED lamp has various advantages: environmental protection property, no pollution, no ultraviolet ray, infrared ray and thermal radiation; the light quality is high, no heat and no radiation are generated due to the fact that ultraviolet rays and infrared rays do not exist in the spectrum, no burden is brought to eyes, and the phenomenon that the eyes feel painful and distended after long-time reading or working is avoided; the color rendering property is good, the fatigue degree of human eyes is reduced, and the eye protection is greatly facilitated; the maintenance cost is low, and the service life of the LED lamp is long. LED lamps are increasingly popular as eye protection lamps for students during learning.

3. Student on the current market all does not consider user's eyes to receive light or the deviation appears when the person considers, for example has some full spectrum's of the name eye-protecting lamp, just does not consider the user and wears the condition of preventing the blue light lens, uses full spectrum's eye-protecting lamp can cause the user to see white object yellow partially when the user wears to prevent the blue light lens, causes user's inconvenience. The user wears to prevent that blue light lens uses general LED lamp simultaneously, and the intensity of general LED lamp blue light is comparatively big, but prevents that the blue light proportion that the blue light lens filters and the intensity of general LED lamp blue light do not necessarily match, can cause the blue light that user's eyes received too much or too little.

4. Currently, in the eye protection lamps for students in the market, the learning efficiency of a user is not promoted by considering the attribute of light, and the expected functions of the user in the aspects of mood, sleep, growth and the like are promoted by considering the attribute of light to adjust the attribute of light according to the habit and the setting of the user after leaving a factory.

5. The patents related to the current LED lamps can be divided into the following categories:

1) the main method of dimming is to adjust the light source so that the light source is changed to assume that the eyes of a person can obtain proper light by the light source, such as the inventions of application numbers 201410735164.9, 201110004079.1 and 201310180067.3, the inventions of application numbers 201410735164.9 and 201310180067.3 take the distance between the eyes of the person into consideration, however, the intensity of light received by human eyes is not considered, and the intensity of light received by human eyes can be estimated only by calculating the distance, so that whether the estimation is accurate or not is only possible, but also only the direction of human eyes, whether glasses are worn or not and the light transmission performance of the glasses can cause that the practical effects of the invention patents of application numbers 201410735164.9 and 201310180067.3 are not ideal and even reversely adjusted under certain conditions, and the invention patents of application numbers 201410735164.9 and 201310180067.3 do not consider that the learning effect of a user is enhanced by intelligently adjusting the light according to the learning time of the user. The invention patents with application numbers of 201410735164.9 and 201310180067.3 only simply detect the intensity of light, do not detect other properties such as the spectrum of light, and have the possibility that the intensity of light is not problematic, but is blue light, and users can not protect eyes but can cause visual impairment by using the eye-protecting lamps with application numbers of 201410735164.9 and 201310180067.3 in such an environment.

2) Light sources, such as patent applications No. 201410431772.0, No. 201410180591.5 and No. 201210136847.3, mainly emit light close to natural light through various types of LEDs, so that the emitted light is suitable for learning and reading, and patent applications No. 201410431772.0, No. 201410180591.5 and No. 201210136847.3 do not consider whether the attributes of background light and light specifically received by eyes of a user are suitable or not, and do not consider the situation that the user wears blue-light-proof glasses.

3) For example, in the invention patent with the authorization number of CN 105611690B and the invention patent with the application number of 201611064603.3, the interaction between the background light and the light that can be adjusted by the invention is not distinguished, and the background light and the light are mixed together, that is, the background light and the light are uniformly calculated as the ambient light, which may cause the dark background under extreme conditions, the light is adjusted to be very bright by the system described in the above patent, and at this time, the pupil of the human eye is opened to be larger, and the very bright light may cause damage to the fundus of the user.

The above analyzed patents are not practical, do not consider the actual light receiving condition of the eyes of the user, and even do not consider the influence of the light on the eyes when the background light is too dark, and the effect is deficient in the actual use.
