With the change of the way of working, more and more people work from outdoors to indoors, and frequently work in front of computer screens. With the increase in working hours and close work, more and more people are suffering from myopia, especially children and teenagers.
In this case, educational lighting has attracted much attention.
Educational lighting is also known as classroom lighting. From kindergarten, primary school, middle school to college, students spend most of their time in the classroom. Therefore, the lighting in the classroom is particularly important, and needs to meet the needs of reading, writing, painting and other activities.
Lamps must meet the horizontal and vertical illumination requirements, and the quality of lamps is also more stringent:
1. Flicker free, no glare, no blue light hazard, no harm to the eyes of children and teenagers.
2. The brightness, illuminance, color temperature, and color rendering of the place should meet the needs of reading, writing, talking and other activities.
3. Energy saving and environmental protection.
Some countries have also formulated lighting standards for different locations. For example, China has formulated lighting standards. Educational lighting needs to meet standards such as illuminance standard value, unified glare level, and color rendering index (Ra).
