Tsis tas li ntawd, nws tseem yuav tsum tau them sai sai rau qhov uniformity ntawm illuminance. Qhov piv ntawm qhov tsawg kawg nkaus illuminance rau qhov nruab nrab illuminance yog hu ua uniformity, thiab feem ntau yuav tsum tsis txhob tsawg tshaj li 0.8. Lub rooj teeb yuav them nyiaj ntau dua rau qhov tsis sib xws ntawm kev teeb pom kev zoo. Rau qhov chaw teeb pom kev ntev ntev, lub teeb pom kev hauv zos yuav tsum tsis txhob tsawg tshaj li ib feem peb ntawm tag nrho cov illuminance. Piv txwv li, thaum peb siv lub rooj teeb, peb yuav tsum tau them sai sai rau tig lub teeb taub hau, kom lub qhov muag yuav tsis raug kho tas li vim rov hloov ntawm lub teeb thiab tsaus.

Kev ua haujlwm sib txawv thiab kev ua neej nyob muaj qhov sib txawv rau qhov ci. Nyob rau hauv qee qhov teeb pom kev zoo, cov ntawv ntsa lossis cov ntaub ntawv uas muaj qhov tsim nyog xav tau siv tau raws li qhov yuav tsum tau ua kom pom kev ci ntsa iab kom tsim nyog thiab ci ntsa iab.

glare

Thaum peb saib ncaj qha rau ntawm lub teeb ci, lossis thaum lub teeb pom kev zoo los ntawm cov khoom muaj ntau dua li qhov ci ntsa iab uas tib neeg lub qhov muag tuaj yeem hloov mus rau, tib neeg lub qhov muag yuav tsis xis nyob thiab yuav tsum zam lossis thaiv nws.
