What are the problems with school classroom lighting?
Students spend most of their time studying in the classroom. If the classroom lighting is not well designed, it is easy to cause visual fatigue. After a long time, it will lead to the decline of students' eyesight and academic performance. Therefore, we must pay attention to the renovation of classroom lighting facilities. So what are the problems with the lighting facilities in the school classrooms, and how should they be solved? Let's take a look with the teaching office lamp manufacturers now!
1. Many school classroom lighting lamps are placed in an unreasonable direction, resulting in glare. The lighting fixtures in school classrooms are generally in the direction of the level and the blackboard, which makes it easy for the light to directly enter people's eyes. When there is excessive brightness or excessive brightness contrast in the field of vision, students will feel dazzling and affect their vision. This dazzling light is glare. Glare is divided into direct glare, reflected glare and contrast glare. The visual effect of glare reduces the visual effect of the work area, causing visual discomfort and distraction, easily causing visual fatigue and damage to eyesight.
Solution: The arrangement of the lamps should be parallel to the long axis and the students' desks, and perpendicular to the blackboard, so that the light of the lamps will enter people's eyes from both sides of the eyes, avoiding direct sunlight; at the same time, put the lamps It is arranged above the vertical blackboard channel, so that the desktop forms side or two sides lighting, and the lighting effect is better.
2. The number of light sources for school classroom lighting is insufficient, resulting in shadows. Insufficient number of light sources is also the cause of projection. Due to the small number of lamps, the distance between the lamps is too large. When the student sits between the two lamps and is close to the latter lamp, the illumination of the former lamp cannot radiate to the position of the latter lamp. It cannot effectively offset the shadows caused by a lamp shining on the human body.
Solution: Because we can't use shadowless lamps like the operating room, we can appropriately increase the number of lamps and change the installation position of the lamps. In places where the light sources are denser, we can appropriately reduce the light intensity and use more low-power lamps. , replacing less high-power lamps.
3. The light source is not fixed. When the fan is turned on, the light source will be unstable. Due to the high height of the school classroom, in order to prevent the light from being affected by the high classroom, the school uses a chandelier to hang the lamp in the mid-air at a certain height from the desktop, and some school classroom lighting uses a soft hanging, that is If the light source is not fixed, when the weather is hot in summer and the fan is turned on, the lamp will keep swinging back and forth, making the light source unstable and affecting the brightness. At the same time, the lamp body keeps shaking, which increases the danger.
Solution: Fix the soft chandelier and use a material with greater hardness to fix the light.
