Why use LED classroom eye protection lights for classroom lighting renovation
Why use LED classroom eye protection LED blackboard light for classroom lighting renovation? What is the basic status quo of student myopia? Let’s take a look now!
According to the analysis report of (Physical Fitness and Health Survey), the myopia rate of primary school students reached 45.71%, and the myopia rate of junior high school students suddenly increased to 74.36%. The myopia rate of high school and college students reached 84.82%. The place where myopia is most induced is at school, and primary and secondary school students 60% of the time It is in the classroom, and the number of myopia patients is increasing year by year.
High myopia rate:
According to the survey of China's first white paper ``National Visual Health'' that systematically studies visual health, the proportion of myopia among people over 5 years old is 35.16% to 39.21%, that is, 1 out of every 3 people is myopia, and the total number of patients with myopia is in Between 437 million and 487 million.
The serious effects of myopia:
1. In the aerospace, precision manufacturing, military and other industries, people who meet the requirements of vision may face a huge gap, which will directly threaten my country's sustainable economic and social development and national security.
2. Induce a variety of diseases, affect learning efficiency, cause physical and mental abnormalities, cause inconvenience in life, and pass it on to the next generation.
3. Poor classroom lighting environment is the main cause of the decline of students’ eyesight. The experiment of the National Natural Science Foundation of China "Research on Healthy Lighting of Classrooms Based on Photobiological Effects" shows more scientifically that school classroom lighting will directly affect students’ learning efficiency. And healthy vision.
Causes of decreased eyesight of students:
1. Congenital genetic factors
2. The electronic equipment has been used for a long time, etc.
3. A learning environment that does not meet the relevant national lighting standards;
4. Use eye hygiene, incorrect sitting posture, and heavy learning burden;
Common problems of domestic classroom lighting:
Most of the students' time is spent in school, especially the pupils whose eyesight is under development. They have been studying intensely under the lighting conditions that do not meet the requirements for a long time, and are suffering from unbearable light pollution, resulting in a general decline in eyesight. And most of the domestic classroom lighting mainly has the following 6 common problems
1. Generally, classrooms are illuminated with high color temperature 6500K fluorescent tubes. Because the light color is too white, it is easy to cause excitement and fatigue of students.
2. Fluorescent lamps are generally equipped with inductive ballasts, which have a serious light stroboscopic effect. In order to adapt to stroboscopic changes, the student's visual system will automatically adjust frequently, which is easy to cause visual fatigue;
3. The color rendering index is too low. Most classrooms use fluorescent lights with a color rendering index of about 70, causing color distortion. Especially in professional classrooms such as art, chemistry, biology, etc., it directly affects students' correct judgment on the color of objects;
4. The exposed fluorescent tube, direct light to the students' eyes will easily produce glare, distract the students, and then reduce the learning efficiency, leading to visual distress and easy to cause myopia;
5. There is no dedicated blackboard lighting, and most of the classroom spaces share fluorescent lights. The average illuminance of the blackboard is very low, causing students to not see the content on the blackboard;
6. The illuminance and uniformity of the illuminance of the desks are generally lower than the national standards. Students who study in a low and uneven lighting environment for a long time can easily cause visual fatigue;
According to the above situation, do you think the eye protection lamp in the classroom is useful? The light source is at least 6-8 hours a day and is indispensable for a long time, so the eye protection lighting renovation project must be implemented
Relevant information shows that, according to the requirements of the "Hygienic Standards for Daylighting and Lighting in Primary and Secondary School Classrooms", the desktop illuminance compliance rate of the school classroom lighting using traditional lamps is less than 40%, and the blackboard illuminance compliance rate of the classroom is less than 10%.
Classroom lighting renovation
Use professional LED energy-saving eye protection classroom lamps:
1. Provide a high-quality light environment, protect eyesight, and improve teaching quality.
① The light source does not directly shine into the eyes, there is no glare, does not hurt the eyes, and avoids distraction of students;
② No light strobe hazard to ensure eye comfort;
③ High color rendering index, strong color reproduction ability, closest to natural light, improve students' ability to recognize colors, and protect vision development;
④ No ultraviolet radiation, no harmful blue light, no noise pollution;
⑤ The light is soft, it is easy to concentrate and improve the learning efficiency.
2. After professional lighting design, the illuminance and uniformity are better than national standards to protect eyesight health.
3. With the same illuminance, it saves more than 50% of electricity, does not contain harmful substances such as mercury and lead, and is energy-saving and environmentally friendly.
4. The average service life of the lamp is more than 30,000 hours, the light decay is small, and the maintenance cost is low.
