Careful people have found that ordinary lamps have only one sole function, which is to illuminate the space, but blackboard lamps are not like this. This type of lamps is very low in terms of brightness. At first, many people thought this The brightness of the product is not up to the standard at all, and it was discovered later that it is not as simple as everyone imagined.
This type of lighting is indeed relatively low in terms of brightness, because its role is not to illuminate at all, but to avoid reflections. Sometimes rainy weather appears, but the course will continue. The teachers will turn on the indoor lighting. It is because it is too bright to cause reflection problems. At this time, some people with poor eyesight cannot see the words on the blackboard clearly. At this time, the teacher cannot stop and wait, so he can only use the blackboard light.
Blackboard light
Many people find that as long as the blackboard lamp is turned on, the characters on the blackboard become clearer. Although it is not an expensive lamp and its brightness is not very high, it has become the natural enemy of the reflection phenomenon, perhaps because of this. , So it will be used in various types of classrooms. If there is no blackboard light, the children's academic performance will be affected to a certain extent.
