What are the problems with classroom lights?
At present, the eyesight problems of primary and middle school students are getting more and more serious. In order to solve this problem, many places choose to use special classroom lights. In fact, there are many reasons that affect the eyesight of students, such as congenital factors, incorrect sitting posture, and long-term viewing of electronic products. But the fundamental reason is that the design of classroom lights is not reasonable enough, so what are the problems with classroom lights? Let us find out together.
1. Many classroom special lamps use simple fluorescent lamps with low quality, low price, high energy consumption, and technology staying at the level of the 1980s and 1990s.
2. There is no special blackboard lamp or the installation of blackboard lamp is not standardized. For example, ordinary simple fluorescent lamp is used as blackboard lamp. Not only the blackboard illumination is low, but the visibility is low. Students can also see the lamp tube when watching the blackboard. Direct glare can easily cause visual fatigue.
3. Many classroom special lamps use inductive ballasts, which have serious stroboscopic effects.
4. Most lighting fixtures use soft hanging, and the ceiling fan is installed above the lighting fixture. When the ceiling fan and the light are turned on at the same time, there will be serious lamp swing and light shaking.
5. Many lamps use fluorescent tubes with a high color temperature (6500K) and a cold light color. The light is too pale and harsh.
In summary, there are problems with special lamps for classrooms. In fact, with the continuous improvement of social technology, the shortcomings of old-fashioned special lamps have been completely improved. The current special lamps do not have the above problems, and as long as they are in use When the design is reasonable, it will not cause the students' visual fatigue, which can effectively reduce the students' myopia. Of course, when you make a purchase, you have to shop around and buy cheap and good-quality lights.
