1.Lux Level (Brightness)
Thawj yam uas peb xav paub txog Lux Level, TV lossis TV tshaj tawm?
Cov txheej txheem lux yog txawv ntawm TV lossis TV tshaj tawm kev sib tw.
Raws li FIFA cov lus qhia teeb pom kev hauv chaw ntau pob,
chav kawm V (xws li xov tooj cua thoob ntiaj teb xws li World Cup) qhov chaw ncaws pob muaj qib siab tshaj plaws ntawm 2400 lux ( ntsug - ntsej muag ntawm cov neeg ncaws pob), thiab 3500 lux ( kab rov tav - turf).
Yog tias qhov chaw ncaws pob yog rau zej zog (kev siv ua si), peb xav tau 200 lux qib. Lub tsev kawm ntawv theem siab lossis tsev kawm qib siab football club tuaj yeem muaj 500 lux.
2.Unformity Standard
Lwm qhov tseem ceeb parameter yog teeb pom kev zoo sib xws.
Nws yog qhov ntsuas ntawm 0 mus rau 1 (max) qhia txog kev faib tawm ntawm lumen thoob plaws hauv kev ua kis las.
Nws yog qhov piv ntawm qhov tsawg kawg nkaus illuminance rau nruab nrab illuminance (U1), los yog qhov piv ntawm yam tsawg kawg nkaus rau siab tshaj plaws (U2).
Li no, yog tias qib lux yog qhov zoo sib xws, hais tias nyob ib puag ncig 650 txog 700 lux, qhov sib txawv ntawm qhov tsawg kawg nkaus thiab siab tshaj tus nqi yog me me, thiab cov uniformity yuav nyob ze rau 1. Lub teeb pom kev zoo ntawm FIFA tus qauv football chaw ntau pob yog 0.7, uas yog qhov nyuaj hauv kev lag luam teeb pom kev zoo.
3. Beam lub kaum sab xis
Rau qhov chaw ncaws pob loj, cov ncej ib txwm nyob deb ntawm qhov chaw ua si, yog li peb xav tau xaiv lub kaum sab xis zoo tshaj plaws, peb muaj 10 degree / 45 degree / 60 degree / 90 degree beam angle xaiv.
4. Xim kub
Cov xim kub uas yuav tsum tau muaj ntawm football hauv av yog loj dua 4000K rau txhua chav kawm. Tab sis peb feem ntau siv 5000-6000K xim kub los ua kom pom kev zoo dua rau cov neeg ua si thiab cov neeg tuaj saib vim tias cov xim no muaj zog dua.
