Where should the classroom lighting design problems?
Students spend most of their time studying in school classrooms. If the lighting environment of the classroom is not done well, it is easy to cause visual fatigue of the students, leading to myopia, please solve it! The mental state must combine the relationship between the natural lighting environment and the classroom lighting. What should we do? What is the relationship between classroom lighting and visual health? Let's take care of it together now.
First of all, consider the difference in lighting, color, temperature and tones between the student area and the podium. In order to enable students to concentrate and facilitate teaching, we must pay attention to the lighting in this area.
Secondly, when the ratio of the ambient light to the main light area is too large, such as no ambient light or low ambient light, students are prone to visual fatigue, distress and inattention.
In addition, when the environment colors are yellow, green, and orange, and the saturation is moderate, students will concentrate on studying and easily recover. On the contrary, when the ambient light and colors are cold, gray, or white, and the saturation is too low or too high, students are easily excited. The higher the light, the more obvious the reflection.
There is also the environment color is too complex and chaotic, when the light contrast is too large, the students' spirits are easily dispersed, which affects the teaching effect.
At present, the development and prospect of modern school classroom lighting design. With the increasing popularity of computers, multimedia, and digital audio and video equipment in classroom teaching, the single teaching model of students reading and writing on desks, blackboards, and book planes is being used in computer screens, large projection screens, keyboards, scene teaching and other audio-visual media The change of teaching mode. The students' visual scope and visual objects in the classroom and traditional single-media visual objects such as paper and blackboard have produced essential differences and differences. It is an indisputable fact that students study and live for a long time in such a complicated visual environment every day. The proportion of myopia among middle school students in our country is increasing. The traditional school classroom lighting theory, lighting model and school classroom lighting design standards are obviously lagging behind the development and needs of today's classroom teaching. Therefore, how to protect the visual health of students and create a scientific, comfortable, pleasant and healthy visual environment for students has become a top priority.
The classroom lighting design is mainly considered from the following aspects:
1. According to the specifications of the classroom, select the specifications and quantity of panel lights suitable for the classroom.
2. Perform lighting simulation and on-site debugging according to the classroom lighting environment, and adjust the classroom lighting uniformity to a comfortable level.
3. Pay attention to the installation of the blackboard lamp and its anti-glare debugging and design, so that it does not produce exposed light sources, and teachers and students cannot directly touch the light sources. Its debugging and results depend more on the characteristics of the lamp itself, rather than experience.
