1. Students-Ensure the horizontal and vertical illumination requirements of visual targets, reduce visual fatigue, concentrate, have high learning efficiency, and meet the requirements of face-to-face communication between students.

2. Teachers-lecture easily, guide students to focus on the teaching demonstration area, light control adapts to different demonstration teaching scenes, and the teaching effect is good.

3. School management-the environment is getting better, the equipment utilization rate is high, and accidents and disasters are prevented.

4. Appropriate illuminance-the average illuminance value maintained on the classroom table should not be less than 300lx, and its illuminance uniformity should not be less than 0.7; The classroom blackboard should be equipped with local lighting, and the average illumination should be not less than 500lx, and the uniformity of illumination should be not less than 0.8.

5. Reduce glare-a visual phenomenon that causes discomfort or reduces the ability of details or targets due to inappropriate brightness distribution or extreme contrast in the field of vision, which is called glare. The contrast between light and shade is too large, which will make people feel uncomfortable when there is glare, and sometimes they can't see things clearly, causing visual fatigue.

In order to reduce the glare area and light screen reflection area of ordinary classrooms, educational lighting lamps should be arranged vertically, that is, the long axis of lamps should be parallel to the main line of sight of students and perpendicular to the blackboard, so as to reduce the luminous area of educational lighting lamps seen by students.

6. The choice of lamps and lanterns-the choice of educational lighting is the most important. At this stage, many universities at home and abroad have cooperated with Qichen Education Lighting, and there are many scholars under its reputation. I believe that Qichen must have its own uniqueness in the field of educational lighting.
