Cov teeb hauv chav kawm suav nrog cov teeb pom kev dub hauv kev nkag siab dav
Peb feem ntau hnov txoj kev npaj tsim teeb pom kev zoo hauv cov chav kawm hauv tsev kawm ntawv: ua qauv hauv chav kawm uas yuav tsum tau nruab nrog 9 chav kawm teeb thiab 3 lub teeb dub. Yog li cov lus nug yog, puas yog lub teeb blackboard tsis yooj yim rau chav kawm teeb? Dab tsi yog qhov sib txawv ntawm cov teeb hauv chav kawm thiab lub teeb blackboard?
Cov teeb hauv chav kawm suav nrog cov teeb pom kev dub hauv qhov dav, tab sis hauv kev tsim cov teeb pom kev hauv tsev kawm ntawv, cov teeb hauv chav kawm tsuas yog hais txog cov teeb uas ci ntsa iab rau cov tub ntxhais kawm lub rooj thiab podiums, tsis suav nrog cov teeb pom kev dub, vim hais tias lub teeb pom kev dub xav tau lwm yam teeb. Tshwj xeeb hauv kev teeb pom kev zoo.
Cov kev qhia tshwj xeeb ntawm cov teeb hauv chav kawm yog txawv ntawm cov teeb pom kev dub
01
Teeb pom kev zoo
Chav kawm teeb illumination 300lx; blackboard teeb 500lx;
02
Kev sib tw
Qhov sib xws ntawm chav kawm teeb≥0.7; lub uniformity ntawm blackboard teeb≥0.8;
03
Cov txheej txheem ntaus ntawv
Lub teeb hauv chav kawm feem ntau yog LED qhov muag tiv thaiv chav kawm teeb. Cov cuab yeej yuav tsum tau teem caij longitudinally (qhov ntev axis ntawm lub teeb yog ncaj nraim mus rau lub blackboard). Qhov kev ncua deb ntawm lub teeb thiab lub rooj yog tsis tsawg tshaj li 1.7 meters. Cov cuab yeej ntawm lub teeb hauv chav kawm yog lub rooj siv qhov siab, qhov siab ntawm lub rooj hauv cov tsev kawm ntawv theem pib thiab theem nrab feem ntau yog li 70cm, thiab qhov siab ntawm lub rooj hauv kindergartens feem ntau yog li 50cm.
Led qhov muag tiv thaiv blackboard teeb khoom, qhov kev ncua deb ntawm lub blackboard yog 0.7m mus rau 1.0m, thiab qhov ncaj nrug ntawm ntug sab sauv ntawm lub blackboard yog 0.1m mus rau 0.2m. Lub illumination lub kaum sab xis ntawm lub blackboard teeb yuav tsum tau kho kom tiv thaiv lub blackboard teeb los ntawm ncaj qha glare rau tus xib fwb.

Txoj kev teeb pom kev zoo
Cov teeb pom kev hauv chav kawm yuav tsum siv tshwj xeeb LED qhov muag-tiv thaiv chav kawm teeb nrog cov yam ntxwv muaj zog lub teeb tawg, vim qhov no yuav ua rau tag nrho cov teeb pom kev zoo ntawm chav kawm ci dua thiab zoo ib yam, lub teeb yuav softer, thiab qhov pom kev yuav zoo dua!
Lub teeb pom kev lag luam dub yuav tsum siv qhov tshwj xeeb coj qhov muag tiv thaiv blackboard teeb nrog asymmetrical muaj zog lub teeb dispersion yam ntxwv, vim hais tias lub teeb pom kev ntawm blackboard tsis tuaj yeem muab tso rau hauv nruab nrab ntawm lub blackboard, tab sis tsuas yog muab tso rau saum lub blackboard, thiab txhawm rau kom ntseeg tau tias lub teeb pom kev zoo ntawm lub teeb pom kev zoo. blackboard' s illuminance thiab illumination uniformity yog siab, Yog li ntawd, tsuas yog lub LED qhov muag-tiv thaiv blackboard teeb nrog asymmetrical muaj zog lub teeb dispersion yam ntxwv yuav siv tau, thiab lub illuminance ntawm ib feem ntawm lub blackboard uas yog ze rau lub blackboard. teeb thiab ib feem ntawm lub blackboard nyob deb ntawm lub blackboard teeb yog tib yam.
