In terms of educational content, we don't need to worry too much. After all, there are countries that control the broad direction. From teaching textbooks to auxiliary materials, our educational capabilities are unquestionable. But in terms of teaching conditions, there is still much to be improved. For example, in our educational lighting environment, nowadays, the myopia level of teenagers has been increasing year by year, and the root cause has been traced back. Or is there a "blem" in educational lighting.


At present, education lighting generally has a series of problems such as illuminance, lighting uniformity, and lighting instability. However, it is relatively simple to eliminate the problems of uniformity of illumination and stability of lighting in the classroom. To increase the illumination, it is necessary to increase the number of light sources or increase the power of the light sources, but this will inevitably increase energy consumption.


When the teacher and student's eyes move from a book (one brightness area) to a blackboard (another brightness area), the visual organs are immediately adjusted to the new brightness level. When the brightness levels of the two areas differ greatly, it can take a long time for the eyes to fully adapt to the new environment. If the difference in brightness is too great, the pupil must change suddenly to adapt to the new visual environment. Such repeated ups and downs will cause visual fatigue and even cause the eyes to become dry and sour, which will have a great impact on human vision in the long run.


Nowadays, the educational lighting environment of most schools currently has certain flaws, which are mainly reflected in the following aspects:


1. Illumination of classroom blackboards and desks is lower than the illumination value specified by national standards, and students have been studying in a low illumination environment for a long time;


2. There is no special blackboard light for education lighting, or the installation of blackboard light is not standardized. For example, ordinary ordinary fluorescent lamps are used as blackboard lights. Not only the blackboard has low illumination, but the visibility is low. When students look at the blackboard, they can see lamps Direct glare, which can easily cause visual fatigue;


3. Educational lighting generally uses simple fluorescent lamps with low quality, low price, high energy consumption, and unsophisticated technology; and more use of inductive ballasts, there is a serious strobe effect;


4. Educational lighting generally uses soft ceilings, and ceiling fans are installed above the lamps. When the ceiling fans and lights are turned on at the same time, there is a serious phenomenon of pendulum and light shaking.
