Ikibuga cyumupira wamaguru cyihariye Igishushanyo mbonera
Dutanga ibishushanyo mbonera byubusa kumikino yumupira wamaguru cyangwa ikibuga cyumupira wamaguru, hamwe nibipimo bitandukanye byimyidagaduro, amashuri yisumbuye, kaminuza, amarushanwa yumwuga n’amahanga.
Amatara yumwuzure wa stade LED yujuje FIFA, Premier League hamwe na Olympic. Ba injeniyeri bacu bazi neza gukoresha DiaLux mugushushanya ibisubizo byiza byo kumurika no gukora raporo zisesengura amafoto. Usibye kukubwira uburyo tugomba gushyira amatara yo hanze, tuzaguha kandi amakosa asanzwe, kugirango ubyirinde. Igenamigambi ryiza nibisabwa kugirango utsindire amasoko.
Ibisabwa kumurika umupira wamaguru
Iki gisabwa gitanga umurongo wo kumurika stade. Reka dushakishe uburyo bwo guhitamo amatara meza.
1. Urwego rwiza (umucyo) rusabwa mukibuga cyumupira wamaguru
Urwego rwiza hagati ya tereviziyo n'amarushanwa atari televiziyo biratandukanye cyane. Nk’uko bitangazwa na Sitade ya FIFA yo kumurika, urwego rwo hejuru rwurwego rwa V (ni ukuvuga Igikombe cyisi nizindi televiziyo mpuzamahanga) kuri stade yumupira wamaguru ni 2400 lux (vertical - isura yumukinnyi wumupira wamaguru) na 3500 lux (horizon - turf). Niba ikibuga cyumupira wamaguru ari icy'abaturage (imyidagaduro), dukeneye urwego 200 rwiza. Amashuri yumupira wamaguru cyangwa kaminuza yumupira wamaguru arashobora kugira 500 lux.
2. Igipimo kimwe
Ikindi kintu cyingenzi ni ukumurika uburinganire. Ni igipimo cya 0 kugeza kuri 1 (ntarengwa), byerekana ikwirakwizwa rya lumen mukibuga. Ni igipimo cyo kumurika byibuze kumurika (U1), cyangwa ikigereranyo cya minisiteri ntarengwa (U2). Kubwibyo, niba urwego rwimyambarire rusa cyane, hafi 650 kugeza 700, itandukaniro riri hagati yagaciro ntarengwa ninshi ntarengwa ni rito cyane kandi uburinganire buzaba hafi ya 1. Ikibuga cyumupira wamaguru cya FIFA gifite uburinganire bwa 0.7, ugereranije bigoye mu nganda zimurika siporo.
3. Ubushyuhe bwamabara
Ubushyuhe rusange bwibara busabwa kurwego rwose rwumupira wamaguru burenze 4000K. Nubwo iki gitekerezo, mubisanzwe turasaba urumuri rwera rukonje (kuva 5000K kugeza 6500K) kugirango rutange urumuri rwiza kubakinnyi ndetse nababareba kuko ayo mabara arusha imbaraga.
Amakosa akunze kwirinda mugihe utegura amatara ya siporo
Kugirango tunoze ireme ryibyo watanze, turashobora kwirinda amakosa akurikira yimikino yo kumurika.
1. Irinde kwanduza urumuri mugushushanya
Stade ikoresha amatara ya LED agera kuri 60.000 kugeza 100.000. Kugenzura nabi isuka rito birashobora kugira ingaruka kubuzima bwabatuye hafi. Urumuri rwinshi rushobora guhindura icyerekezo cy'abakoresha umuhanda kandi bigahungabanya ubuzima bw'abanyamaguru.
Kugira ngo iki kibazo gikemuke, amatara yacu ya stade LED afite ibikoresho birwanya anti-glare na optique neza kugirango yereke urumuri ahantu hagenewe kugabanya gutakaza urumuri. Mubyongeyeho, turashobora gukoresha amatara yumwuzure hamwe nuduce duto duto, bityo amatara akaba menshi.
2. Ubuzima bw'itara
Bamwe mu bakora amashanyarazi barashobora kwirengagiza ubuzima bwitara. Mubyukuri, itara rimara imyaka irenga 20 nigitekerezo cyiza kubafite stade. Gusimburwa kenshi bisobanura kandi amafaranga menshi yo kubungabunga. Amatara yacu ya LED afite ubuzima bwamasaha 80.000, ahwanye nimyaka 27 iyo ifunguye amasaha 8 kumunsi.
3. Ikibazo cya Flickering mubishushanyo mbonera
Iki kibazo kigaragara cyane mubibuga byumupira wamaguru byakira amarushanwa ya tereviziyo mpuzamahanga. Mu gushushanya amatara, dukwiye kwemeza ko kumurika ikibuga cyumupira wamaguru bidahungabana munsi ya kamera igenda; bitabaye ibyo, bizagira ingaruka cyane kubireba abareba. Itara rya strobe rizagira ingaruka kumucamanza mugihe cyo gukina kandi bizatuma stade yawe isa nkidasanzwe.
Nubwo bimeze gurtyo, amatara yimikino yacu yagenewe kamera yihuta. Igipimo cyabo cyo guhindagurika kiri munsi ya 0.3%, ukurikije ibipimo mpuzamahanga byo gutangaza.
Urebye ibintu byose byavuzwe haruguru, amahirwe yawe yo gutsinda azongerwa cyane. Urashobora kubona inama zumwuga kandi nziza zo kumurika utwandikira.
