Maktab ovoz yozish va eshittirish sinfining yoritilishini qanday o'rnatish va disk raskadrovka qilish kerak?
Online education courses have become a new trend at the moment, so the number of recording and broadcasting classrooms is gradually increasing, but many users report that the pictures of the course videos are blue and red, and the teacher's face is black. There are two reasons for this explanation: ①: The professional recording and broadcasting classroom lamps were not selected; ②: The classroom lamps were not installed and debugged by professional engineers after the installation of the classroom lamps.
Yozuv va eshittirish sinfini yoritish uchun lampalarni tanlashda ikkita nuqtaga e'tibor qaratish lozim: yorug'likning rang harorati, yaxshisi 4000K, yozish va eshittirish sinfida ishlatiladigan kameralarning tortishish talablariga javob beradi. bir vaqtning o'zida suratga olish rasmining mavimsi yoki qizg'ish bo'lishi hodisasidan qochadi; Rangni ko'rsatish indeksi 85 dan katta, bu sahnaning holatini real tarzda aks ettiradi va rasm yanada aniqroq.
Yozuv va eshittirish sinfida yoritishni o'rnatish va disk raskadrovka qilish professional ro'yxatga olish va eshittirish sinfining asosiy mazmuni bo'lib, onlayn kurslarning ro'yxatga olish effektiga bevosita ta'sir qiladi. Yozuv va eshittirish sinfini o'rnatish va disk raskadrovka qilishda qanday omillarga e'tibor berish kerak?
1. Chiroqlarni o'rnatish: birinchi navbatda ovoz yozish va eshittirish sinfining qavat balandligiga qarang. Umuman olganda, ovoz yozish va radioeshittirish xonasi oddiy sinfdan o'zgartiriladi. Zamin balandligi 3 dan 3,5 metrgacha. Sozlanishi burchakli LED yig'ilish xonasi yoritgichi. Yozuv va eshittirish sinfining shiftini uchun asosan 2 tur mavjud. Gipsokarton shipi to'rtburchaklar LED konferentsiya xonasi chiroqlaridan yasalgan bo'lishi kerak. Ochilishning o'lchami kichik va o'rnatish oddiy va oqlangan. U to'g'ridan-to'g'ri ship tuzilishiga kiritilgan, teshiklarni ochishning hojati yo'q va o'rnatish qulay.
2. Chiroqning joylashuvi: professional ovoz yozish va radioeshittirish sinflarining yuqori yorug'ligi doskadan 600-1200 mm, sirt yorug'ligi esa ustki yorug'likdan 1200-1800 mm masofada joylashgan. Yoritgichlarning joylashuvi turli o'lchamdagi va ehtiyojlarning ro'yxatga olish va radioeshittirish sinflariga mos ravishda joyida sozlanishi mumkin.
3. The distance between the lamps and the teacher: the teacher is the main character in the recording and broadcasting classroom. The quality of the teacher's image can lead to the quality of the course. The top light should be installed at the top of the teacher, and the horizontal distance between the face light and the teacher It is 1200-1800mm, and the face light should use adjustable-angle lamps to illuminate the teacher's face to highlight the teacher's facial contour.
4. Lighting illuminance: The central illuminance of professional recording and broadcasting classroom lighting is 600-800lux, and dimmable LED conference room lamps should be selected, which can control the brightness of the lamps and make the recording and broadcasting classroom lighting meet the relevant illuminance requirements, and at the same time not It will be too bright and dazzling, and it will not be too dark to see the teacher's facial expression.
