Sinf taxtasi chiroqlarini o'rnatish standartlari qanday?
Doska talabalar shaharchasida ajralmas o'qitish vositasidir. Endi jamiyatning rivojlanishi bilan maktabda asl doska asosan yo'q qilindi va multimediali yoritish taxtalaridan foydalanish targ'ib qilinmoqda. Xo'sh, sinfdagi doska chiroqlarini o'rnatish standartlari qanday? Keyingi, bizning kichik, sizni tanishtirishga ruxsat bering.
Doska yoritgichining vertikal yoritilishi sinfning o‘rtacha gorizontal yoritilganlik qiymatidan past bo‘lmasligi va sinfning o‘rtacha gorizontal yoritilganlik qiymatidan 1,5 barobar past bo‘lmasligi kerak. Doskadagi yorug'lik darajasi 500 dan, doskadagi yorug'likning bir xilligi esa 0,7 dan kam bo'lmasligi kerak. Doskaning bir tomonida sinfni yoritish uchun ma'lum quvvatga ega quvvat taqsimlash qutisi va kuchli va zaif oqim uskunalari uchun rozetkalarni o'rnatish mumkin. Qora taxta yorug'lik yoritgichi alohida o'rnatilishi kerak. Doskaga qaragan talabalarning ko'rish burchagi past bo'ladi. Doska yoritgichi o'quvchilar uchun to'g'ridan-to'g'ri ko'zni qamashtirmasligi kerak. Doskaga yozishda yoki o‘quvchilarga yuzma-yuz turganda, o‘qituvchilarga doska chiroqlarining to‘g‘ridan-to‘g‘ri ta’sir qilishi kerak.
Therefore, the blackboard lamp should be a special lamp with asymmetric light intensity that projects light toward the blackboard, or a fluorescent lamp with good shading can be used, and it should be set at an elevation angle of 45 degrees above the teacher's horizontal line of sight. Blackboard lighting has a great impact on students' eyesight. When designing blackboard lights, the main light position is selected to prevent the reflection of the light curtain. The installation position of the blackboard light should determine the distance between the blackboard light and the blackboard according to the installation height of the lamp. The elevation angle formed by the horizontal line of the center of the blackboard and the line connecting the center and the light source is around 55 degrees, and the vertical illuminance value is the highest.
Yuqoridagilar biz sizga taqdim etayotgan kichik bilimlar, sizga yordam berishga umid qilaman, agar siz kampus ob'ektlari haqida ko'proq bilmoqchi bo'lsangiz, biz bilan maslahatlashish uchun BENWEI yoritish rasmiy veb-saytiga kirishingiz mumkin, ko'proq ma'lumotni veb-saytimizda topishingiz mumkin.
