A ellir gosod y golau bwrdd du ar y wal?
Mae'r offer addysgu mewn ysgolion hefyd wedi gwneud cynnydd mawr gyda datblygiad cymdeithas. Cymerwch y bwrdd du hwn fel enghraifft. Mae llawer o ysgolion wedi newid i fyrddau du amlgyfrwng, hynny yw, mae'r delweddau'n cael eu hadlewyrchu ar y bwrdd du trwy'r taflunydd, ond mae'n rhaid bod goleuadau ar y bwrdd du, felly a all y goleuadau bwrdd du gael eu gosod ar y wal? Nesaf, bydd ein golygydd yn ei gyflwyno i chi.
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.
Trwy gyflwyniad ein golygydd uchod, a oes gennych chi ddealltwriaeth benodol o'r broblem hon? Argymhellir eich bod yn meistroli mwy o wybodaeth am gyfleusterau'r campws bob dydd. Dim ond trwy wybod mwy y gallwch chi gael dealltwriaeth dda o beryglon cudd goleuadau bwrdd du yn yr ystafell ddosbarth. datrys.
