Problems and solutions of special eye-protection lamps for classrooms
Nowadays, the myopia rate of students is getting more and more serious. However, students spend most of their time in the classroom. Therefore, in order to solve the problem of myopia rate in many places, they will choose to use special lamps for classrooms, but many users will report that they have used them. How does this kind of special lamp feel still not improved? This is not a question about the lamp, but there are certain problems when you use it, so it has no effect. Then what problems do you have when you use it? How to solve it? Let's take a look together.
1. Many classroom special lamps are placed in unreasonable directions, causing glare. Classroom lighting fixtures are generally horizontal and the direction of the blackboard, so that it is easy to make the light directly into the eyes of people. When there is too high brightness or too large brightness contrast in the field of view, students will feel dazzling, which affects the degree of 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, produces visual discomfort and distraction, easily causes visual fatigue and damages eyesight.
Solution: The arrangement of special lamps for classrooms should be parallel to the long axis and the students’ desks, and perpendicular to the blackboard, so that the light from the lamps will enter people’s eyes from both sides of the eyes, avoiding direct sunlight; at the same time, Arrange the lamps and lanterns above the vertical blackboard passage, so that the tabletop forms the side or both sides of the lighting, and the lighting effect is better.
2. The number of light sources for the classroom dedicated lamps is insufficient, causing shadows. Insufficient number of light sources is also the cause of projection. Due to the small number of lamps, the distance between the lamp and the lamp is too large. When the student sits between the two lamps and is close to the latter lamp, the illuminance of the previous lamp cannot radiate to the position of the latter lamp. It cannot effectively offset the shadow caused by a lamp shining on the human body.
Solution: Because we can’t use shadowless lights like the operating room, we can increase the number of dedicated lights and change the installation position of the lights at the same time. In places with dense light sources, we can appropriately reduce the light intensity and use more low-power lights. Lamps, replacing less high-power lamps.
3. The light source of the classroom dedicated lamp is not fixed. When the fan is turned on, the light source will be unstable. Due to the high height of the classroom, in order to prevent the brightness of the classroom from being affected by the height of the classroom, the lamp is suspended in the mid-air at a certain height from the desktop. Some classrooms use soft hanging, that is, the light source is not used. Fixed, when the weather is hot in summer, when the fan is turned on, the lamp will constantly swing 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 harder material to fix the lamp.
In summary, there are problems and solutions when using special lamps for classrooms. Is it true that many people suddenly realize after seeing them? It does not mean that the special lamps will be improved after the use of special lamps, but we need to install them correctly. And the distance is used, so after we make the purchase, we must strictly follow the correct installation method and distance to use, so that the special lamp can exert the corresponding use effect.
