Can the blackboard light be mounted on the wall?
The teaching equipment in schools has also made great progress with the development of society. Take this blackboard as an example. Many schools have changed to multimedia blackboards, that is to say, the images are reflected on the blackboard through the projector, but There must be lights on the blackboard, so can the blackboard lights be mounted on the wall? Next, our editor will introduce it to you.
According to our understanding, the blackboard light can be installed on the wall. The blackboard light is a kind of lighting for the convenience of the projector to reflect on the blackboard. Its brightness and position are very important. The installation of the blackboard light must be based on the blackboard and projection. The distance of the projector and the degree of reflection are installed. If the distance is too far or there is a deviation of the orientation, the projector cannot reflect the image on the blackboard, which will also affect the students' learning.
The conflict between the school's existing blackboard lights and projectors. Since most of the blackboard lights are currently suspended fluorescent lights or can only illuminate vertically, after the projector is put away, the blackboard projected by the projector has no light projected past, and students generally report that the content of the projection cannot be seen clearly; second, the existing The angle transmitted by the blackboard light is not put on the blackboard, but on the white wall above the blackboard, which not only fails to achieve the proper illumination for students to read the content on the blackboard, but also causes reflection in sunny weather and sunlight. , resulting in serious glare on the blackboard, hindering students' reading, resulting in students' vision loss.
Through the introduction of our editor above, do you have a certain understanding of this problem? It is recommended that you master more knowledge about campus facilities every day. Only by knowing more can you get a good understanding of the hidden dangers of classroom blackboard lighting. solve.
