In recent years, the country’s investment in basic education has been increasing, but the number of myopic students in primary and secondary schools has increased rapidly. The survey found that poor classroom lighting environment is one of the main reasons for the decline of students’ eyesight.
At present, most of the classroom lighting in primary and secondary schools in China use fluorescent lamps as light sources, or directly use the “lamp support (including electrical components) + bare lamps”, or use “lamps (grid lamp panel/blackboard lamp ) + Fluorescent tube light source method. Most of this type of lighting has the problems of generally insufficient desk illumination, poor uniformity of blackboard lighting, obvious glare easily irritating eyes, and high color temperature easily causing visual fatigue.
Primary and elementary schools, as a place where students live and study for a long time, a healthy light environment plays a positive role in promoting the growth of primary and middle school students.
The LED intelligent lighting system can meet the requirements of all standard contrast and uniformity of classroom lighting. When the total luminous flux of each lamp panel of the three-dimensional lighting LED lamp panel is 3000lm, it is at a level of 0.75m (lesson table height) 7.0m X5.6m The desk area of the student’s class, the illuminance maintenance value (maintenance factor is 0.8) is 336lx, and the illuminance uniformity can be 0.82. The three-dimensional lighting LED lamp panel with increased side and backlighting has a good performance in increasing the uniformity of the three-dimensional space and reducing the glare effect in the space.
