How to create a classroom lighting environment for health sciences
What harm does the poor lighting in the classroom cause to the eyes? Students are still in the growth and development period. Inferior classroom lighting fixtures will have problems such as flickering and glare. They read and study under this kind of lighting day after day. It will bring eye fatigue to the eyes, and even become an external factor that causes myopia. Some classrooms use old fluorescent lights. Because they are used for a long time, the two ends will turn black and there will be noise. These seemingly inconspicuous small problems will subtly affect the health of students.
In schools, there are many types of buildings, including not only teaching buildings, libraries, but also sports centers (including stadiums/halls, open-air playgrounds, etc.), canteens, dormitories, student activity centers, cultural exchange centers, etc. The classroom is the main place for students to study. The quality of its lighting environment directly affects the students' vision, eye fatigue and concentration. Therefore, a healthy and scientific lighting environment is one of the necessary conditions for students to learn. It provides protection for the visual work of school education, meets the visual work requirements of students and teachers, protects eyesight, and improves teaching and learning efficiency. How to provide a good classroom lighting design? Let's learn about it now!
A good classroom lighting design should meet the following standards:
1. Meet the basic requirements of students for reading, writing, and painting, ensure the horizontal and vertical illuminance requirements of the visual target, meet the desktop average illuminance value not less than 300lx, and its illuminance uniformity should not be less than 0.7.
2. Satisfy the color rendering index greater than 80, good glare control (glare value UGR<19), reduce light curtain reflection, protect eyesight, and improve visual function and visibility.
3. To guide students to focus on the teaching or demonstration area, while ensuring that the color temperature is between 4500K-5500K, in order to achieve a comfortable lighting environment.
4. To meet the requirements of face-to-face communication between students, the brightness distribution should be reasonable, meet the average illuminance value of 300lx, and the illuminance uniformity should not be less than 0.7.
5. Lighting control should be adapted to different demonstration and teaching situations, and the influence of natural light should be considered.
6. Classroom lighting should also be safe, reliable, convenient for maintenance and repair, and coordinated with the environment.
For a good classroom lighting environment, it is also important to choose high-quality classroom lighting fixtures. The eye-protecting classroom lamps developed and produced by Benwei Lighting use high-efficiency, energy-saving, high-quality LED light sources, IC constant current and non-flicker control power supplies. The lamps adopt professional optical design, use small grille anti-glare technology, and the lamp body is made of light-transmitting materials. The light will be emitted to create a healthy, comfortable and uniform classroom lighting environment.
At the same time, in the classroom lighting, the blackboard lighting is the key lighting, and the blackboard bears the important task of transmitting knowledge points. The utilization rate of blackboards in general classrooms is very high, and blackboard lighting must be considered from the perspective of students and teachers.
Then, to create a good blackboard lighting, you need to do the following:
1. The blackboard is the focus point of the students' attention. It needs a higher vertical illuminance, and it needs to meet the standard value ≥500lux.
2. As the blackboard is the key area for displaying knowledge, the more uniform the light distribution, the more comfortable the visual experience, and the uniformity of illumination ≥0.8.
3. Reflected glare and direct glare are very easy to appear in blackboard lighting. In order to eliminate the effect of glare in blackboard lighting, the following three conditions need to be met. The blackboard lighting does not enter the eyes of the students through the reflected light from the blackboard surface; the light source of the blackboard lighting does not directly enter the eyes of the students; the teacher will not feel the blackboard lighting dazzling.
4. In order to avoid problems such as reflected glare and direct glare, the installation position and angle of the blackboard lamp need to be professionally designed.
5. In order to facilitate the blackboard light to change according to different teaching environments, it is recommended that the blackboard lighting needs to be controlled separately.
6. In addition to satisfying the above points, high-quality blackboard lamps play a pivotal role. The eye-protecting blackboard lamp developed and produced by Benwei Lighting adopts an optical lens design to adjust the light output route to eliminate glare and not glare to achieve the lighting effect of the blackboard.
