Vim li cas thiaj yuav tsum tau siv lub teeb pom kev zoo nrog lub teeb pom kev zoo asymmetric rau lub teeb pom kev zoo? Vim tias lub teeb dub tsis tuaj yeem muab tso rau hauv qhov chaw ntsug ntawm lub blackboard, nws tsuas tuaj yeem muab tso rau saum lub blackboard, thiab txhawm rau ua kom lub teeb pom kev zoo ntawm lub blackboard, nws tsuas tuaj yeem siv lub teeb blackboard nrog asymmetric muaj zog lub teeb faib cov yam ntxwv. lub illumination ntawm ib feem ntawm lub blackboard nyob ze ntawm lub blackboard lub teeb thiab ib feem ntawm lub blackboard deb ntawm lub blackboard lub teeb kom zoo ib yam.
Chav kawm teeb pom kev zoo dimming system yog tswj los ntawm ntau lub voj voog. Txhua lub teeb nyob rau hauv thawj kab rov tav kab ntawm chav kawm teeb yuav tsum tau tswj los ntawm ib tug cais voj hloov. Thaum siv kev qhia multimedia, lub teeb pom kev zoo tuaj yeem hloov kho nyias. Txhua qhov ntawm lwm cov kab teeb yog tswj los ntawm ib qho kev ywj pheej hloov hluav taws xob. Blackboard teeb pom kev zoo yuav tsum tau tswj los ntawm ntau lub voj voog, thiab txhua lub teeb yuav tsum tau tswj los ntawm lub voj voog cais. Thaum siv multimedia qhia, teeb pom kev zoo thiab illuminance tuaj yeem hloov kho nyias.
Raws li kev paub ntau yam, LED cov chav kawm ua haujlwm blackboard teeb tuaj yeem ua tiav qhov nruab nrab illuminance ntawm 700 lux ntawm lub blackboard, uas ua tau raws li lub teb chaws tus qauv yuav tsum muaj ntau tshaj 500 lux, lub glare tus nqi ntawm lub blackboard yog 17, thiab lub illumination ntawm lub blackboard yog ci thiab sib xws, txawm tias nws yuav tsis cuam tshuam rau cov tub ntxhais kawm hauv kab rov qab. Los ntawm cov tsos thiab tag nrho, nws tsim ib tug nyob ntsiag to, huv si, xis thiab kaj chav kawm ntawv rau cov tub ntxhais kawm.
