One, light radiation
The first are retinal blue light damage, near ultraviolet and retinal thermal damage. Second adverse consequences: light-induced inflammation of the cornea, conjunctiva, cataracts, retinal problems, and skin diseases caused.
Second, blue light
For example, the mobile phone has a mode that is anti-blue light, anti-blue light mobile phone film, if the blue light of 400 to 500 nanometers in the light is too high, it will damage the retina. Adolescents are in the stage of growth and development and are very sensitive to this. Of course, whether it can cause harm or not, the imaging luminance meter also needs to see the relevant dose size.
Third, the light
The concept of glare refers to the inappropriate distribution or range of brightness, which is manifested as extreme proportions in space or time. Excessive glare will make the eyes uncomfortable and visibility will be greatly reduced. Now, more and more lighting manufacturers are beginning to pay attention to this parameter, and it is a parameter to comment on the quality of lighting.
Fourth, Flicker
This can't be seen with the eyes, and the lack of it can hurt the eyes. The primary and secondary school students are between 6 and 13 years old, and their eyes are relatively delicate. If they are kept in such an environment, their eyesight will decline. Even adults working under strong Flicker lights can cause adverse visual effects. Scientists also study brain disorders such as migraines.
For decades, due to insufficient attention to lamps, the myopia group has been too large. Now is the time for improvement.
Good light can create a positive and comfortable environment for students. Classes and studies in such a place will make people more pleasant. Luminance meters, lighting companies have begun to pay attention to the LED industry, making more excellent and cost-effective lamps, as well as the future of intelligent and healthy lighting.
The new products of some lighting companies cover a variety of different industries, and in educational lighting, investment continues to increase, and the industrial chain has been vigorously improved. This industry has formed a new outlet, so as to achieve corporate profits and improve school lighting environment. , to protect the eyesight of young people.
In terms of lighting product technology, it is necessary to improve the products to meet the requirements of the school, from illuminance, glare,Flicker, color temperature, blue light, and color rendering value to six directions to ensure that each parameter meets the requirements.
At the same time, the new Internet of Things integrates lighting, from the previous manual control of lamps to intelligent control, thus achieving energy saving, suitable for various scenes, and easier to control, such as smart phones, or related panels.
