Educational lighting improves teaching and learning efficiency

School is the main place for students to study and activities. According to statistics, a student spends 60% of his time in school every day. For students, school is their second home. In school time, lighting is an unavoidable factor. Good lighting can allow students to meet new challenges with full enthusiasm, while poor lighting will affect students' physical and mental health!

The purpose of educational lighting is to create a good environment for the visual work of school education, to meet the visual work requirements of students and teachers, to protect vision, and to improve teaching and learning efficiency.

The main type of education lighting is classroom lighting. The general teaching style is divided into formal teaching and interactive teaching. Formal teaching is mainly the exchange between teachers and students, that is, teachers read lesson plans, observe students, write on the blackboard, students read books, write, Look at the words and figures on the blackboard, watch the teacher's presentation, etc.

Interactive teaching increases communication between students, and students should be able to see each other's expressions clearly. At present, teaching methods such as projection are also used in teaching. Schools mainly use daytime teaching to effectively use natural light to save energy. Therefore, the basic task in classroom lighting is to meet the daily needs of teachers and students!

According to the "School Illumination Standard", the desk illumination of the classroom should be greater than 300Lx. At present, some schools may pursue the illumination one-sidedly or the design is not reasonable (the illumination reaches 800-100Lx). The effect is that students' books and desks form a strong reflective glare, students feel tired, and the school pays more for electricity, and then has to remove half of the educational lighting.

The problem of high brightness is also reflected in the "sunshine" classroom facing south. Generally speaking, the sunlight on the desktop can reach thousands of lux (Lx) or more. Under this kind of high illumination, students can't see the teacher's blackboard writing on the blackboard, causing severe visual fatigue.

To prevent sunlight from shining directly on the table, curtains must be installed in the school's south-facing classroom. It is recommended that schools can be equipped with a portable light meter to check the state of education illumination. In order to analyze the uniformity of the illumination in the classroom, it is also possible to understand the light decay phenomenon that occurs when the lighting fixtures are used for a long time, so as to replace the educational lighting fixtures in time.
