Is educational lighting really the higher the illuminance, the better?
School is the main place for students to study and carry out activities. According to statistics, a student spends 60 percent of their time in school every day. For students, school is their second home. In school time, lighting is an unavoidable factor. Good lighting can make students 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, provide guarantee for the visual work of school education, meet the visual work requirements of students and teachers, protect eyesight, and improve the efficiency of teaching and learning.
The most important part of educational lighting is classroom lighting. The general teaching forms are divided into formal teaching and interactive teaching. Formal teaching is mainly the communication between teachers and students, that is, teachers read lesson plans, observe students, write on the blackboard, and students read and write. , Look at the words and pictures on the blackboard, watch the teacher's demonstration, etc.
Interactive teaching increases the 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. The school mainly focuses on teaching during the day, and effectively uses natural light to save energy. Therefore, the most basic task in classroom lighting is to meet the daily needs of teachers and students!
Referring to the "School Illuminance Standard", the illuminance of the classroom desktop should be greater than 300Lx. At present, some schools may one-sidedly pursue the illuminance, or the design is unreasonable (the illuminance reaches 800-100Lx). The effect is that students' books and desk tops form strong reflection glare, students feel tired, and the school pays more for electricity, and finally half of the educational lighting has to be removed.
The problem of high brightness is also reflected in the "sunshine" classrooms facing south. Generally speaking, the illuminance of sunlight on the desktop can reach more than several thousand lux (Lx). Under this high illuminance, students cannot see the teacher's writing on the blackboard clearly, causing serious visual fatigue.
In order to prevent the sunlight from directly shining on the desktop, curtains must be installed in the south-facing classrooms of the school. It is recommended that schools be equipped with a portable illuminance meter to check the illuminance status of educational lighting. In order to analyze the uniformity of illuminance in the classroom, it can also 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.
Educational lighting, aiming at the problems existing in the field of educational lighting, designed professional educational lighting fixtures, which can well meet the daily needs of teachers and students. The classroom lighting fixtures are all metal heat dissipation, light weight, high CRI, no stroboscopic, blue light level reaches RG0, and also has the most critical UGR<15 anti-glare="" design,="" providing="" classroom="" lighting="" in="" all="" directions="" and="" angles.="">
