Eye protection table lamp used by students

[ Huaqiang Security Network News ]
Do you know the eye protection table lamp used by students? Everyone knows that protecting the eyes is the homework of our life, and the eye protection should start from an early age. Students are in the stage of rapid physical growth, and should protect the windows of the soul. Eye protection can be reflected in many details. LED eye protection table lamp can greatly relieve visual fatigue and protect eyes from injury. How to choose the LED eye protection table lamp, how to use the LED eye protection table lamp correctly during the learning process, the fire wolf Xiaobian and everyone to understand.
LED eye protection desk lamps are generally used in office or learning lighting places such as reading, writing, designing, and reviewing. For those who do desktop learning, ensuring a good visual environment in the work area is of great benefit to improving the quality of learning and office, improving work efficiency, and protecting health. Only by fully understanding the characteristics of lighting and choosing the right lighting, can we make our study and work easier and more comfortable, the body becomes healthier, life becomes more colorful, and work becomes more enjoyable.
In places where LED desk lamps are used, if the illumination and color rendering of the lamps are insufficient, the reader will over-examine the vision, causing eye fatigue, and the long-term strobe or glare of the light will cause serious damage to the human nervous system. Therefore, we must pay special attention to the quality of lighting. From the perspective of satisfying the comfort and health of human lighting and considering energy conservation, LED eye protection lamps should have five conditions:

1, desktop lighting should have enough illumination
At present, the lighting design standards commonly used in lighting places such as schools and office buildings in China are formulated in the 1980s. The table illumination standard for office and study is only 1/2 of the international standard, and the international standard is 300-500 lux (lx). Our country is about 150 lux. Too low or too high illumination can make reading difficult, which can cause reading fatigue and affect reading and work efficiency.
2, the light should be stable
If the light is "bright" enough, but it is constantly "flashing", the light is not stable enough, we say it has "strobe". When the strobe exceeds a certain range, visual fatigue occurs. Long-term visual fatigue can cause damage to the human visual system. Especially in today's increasingly popular computer, many people use computers under the light. Usually, the strobe of the fluorescent ballast of the magnetic ballast and the frame of the fluorescent screen flicker (replace the picture 50-100 times per second) to form an optical resonance. The human visual system is more harmful. Reading or working in this lighting environment for a long time can damage the eyes, and there are symptoms such as eye swelling and headache, and usually no reason can be found.
3, the color rendering index is not less than 80
The color rendering index is the degree of reduction of light to color - we call it color rendering. In the light with a low color rendering index (general fluorescent light is 60-70), the eye has a low ability to distinguish colors and is prone to visual fatigue. The color rendering index of general desk lighting should be no less than 80.
4, no glare
When the human eye is affected by glare, it will feel the stimulation and oppression and lose the bright and comfortable atmosphere. If the time is long, it will cause moodiness, anxiety and anxiety, which will have serious adverse effects on reading and work.
5, the use of green lighting products
Promoting the adoption of energy-saving light sources has always been China's energy-saving policy. Promoting green lighting means being environmentally friendly. It is necessary to make lighting products not adversely affect the environment, and at the same time reflect the lighting culture of modern civilization. The core of green lighting is to choose high-efficiency, energy-saving and environmentally friendly light sources, accessories and lamps. Only by fully conserving energy can the power plant reduce atmospheric CO2, SO2 and NOx emissions, thereby reducing the greenhouse effect that causes global warming, reducing the occurrence of acid rain, and avoiding the long-term living in a certain concentration of SO2 and NOx air. And other diseases.
