Kif tinstalla u tiddibaggja d-dawl tal-klassi tar-reġistrazzjoni u tax-xandir tal-iskola?
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.
Żewġ punti għandhom jingħataw attenzjoni meta jagħżlu lampi għad-dawl tal-klassi tar-reġistrazzjoni u x-xandir: it-temperatura tal-kulur tad-dawl, preferibbilment 4000K, hija adattata għar-rekwiżiti tal-isparar tal-kameras użati fil-klassi tar-reġistrazzjoni u x-xandir, u fil- istess ħin jevita l-fenomenu li l-istampa isparar huwa blu jew ħamrani; L-indiċi tal-għoti tal-kulur huwa akbar minn 85, li jirrifletti s-sitwazzjoni tax-xena b'mod realistiku, u l-istampa hija aktar realistika.
L-installazzjoni u d-debugging tad-dawl fi klassi ta 'reġistrazzjoni u xandir hija l-kontenut ewlieni ta' klassi professjonali ta 'reġistrazzjoni u xandir, li taffettwa direttament l-effett ta' reġistrazzjoni ta 'korsijiet onlajn. Liema fatturi għandhom jingħataw attenzjoni fl-installazzjoni u d-debugging tal-klassi tar-reġistrazzjoni u x-xandir?
1. Installazzjoni ta 'lampi: l-ewwel ħarsa lejn l-għoli tal-art tal-klassi tar-reġistrazzjoni u x-xandir. B'mod ġenerali, il-klassi tar-reġistrazzjoni u x-xandir hija trasformata minn klassi ordinarja. L-għoli tal-art huwa bejn 3 u 3.5 metri. Angolu aġġustabbli LED kamra tal-laqgħat tad-dawl. Għal-limitu tal-klassi tar-reġistrazzjoni u x-xandir, hemm prinċipalment 2 tipi. Is-saqaf tal-bord tal-ġibs għandu jkun magħmul minn dwal tal-kamra tal-konferenzi LED rettangolari. Id-daqs tal-ftuħ huwa żgħir, u l-installazzjoni hija sempliċi u eleganti. Huwa direttament inkorporat fl-istruttura tas-saqaf, l-ebda ħtieġa li tiftaħ toqob, u l-installazzjoni hija konvenjenti.
2. Post tal-bozza: id-dawl ta 'fuq tal-klassijiet ta' reġistrazzjoni u xandir professjonali huwa 600 -1200mm 'il bogħod mill-blackboard, u d-dawl tal-wiċċ huwa 1200-1800mm 'il bogħod mid-dawl ta' fuq. Il-post tal-lampi jista 'jiġi aġġustat fuq il-post skont il-klassijiet ta' reġistrazzjoni u xandir ta 'daqsijiet u bżonnijiet differenti.
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.
