For students, school is their second home. In school time, lighting is an unavoidable factor. Good lighting can make students meet new challenges with full enthusiasm, while poor lighting will affect students' physical and mental health!

The most important part of educational lighting is classroom lighting. The general teaching forms are divided into formal teaching and interactive teaching. Formal teaching is mainly the communication between teachers and students, that is, teachers read lesson plans, observe students, write on the blackboard, and students read and write. , Look at the words and pictures on the blackboard, watch the teacher's demonstration, etc.

Referring to the "School Illuminance Standard", the illuminance of the classroom desktop should be greater than 300Lx. At present, some schools may one-sidedly pursue the illuminance, or the design is unreasonable (the illuminance reaches 800-100Lx). The effect is that students' books and desk tops form strong reflection glare, students feel tired, and the school pays more for electricity, and finally half of the educational lighting has to be removed.
The problem of high brightness is also reflected in the "sunshine" classrooms facing south. Generally speaking, the illuminance of sunlight on the desktop can reach more than several thousand lux (Lx). Under this high illuminance, students cannot see the teacher's writing on the blackboard clearly, causing serious visual fatigue.
Txhawm rau tiv thaiv kom tsis txhob tshav ntuj ncaj qha rau ntawm lub desktop, cov ntaub thaiv yuav tsum tau nruab rau sab qab teb -faus cov chav kawm ntawm lub tsev kawm ntawv. Nws raug pom zoo tias cov tsev kawm ntawv yuav tsum tau nruab nrog lub ntsuas hluav taws xob portable los xyuas qhov teeb pom kev zoo ntawm kev kawm teeb pom kev zoo. Txhawm rau txheeb xyuas qhov tsis sib xws ntawm cov teeb pom kev zoo hauv chav kawm, nws tseem tuaj yeem nkag siab qhov tshwm sim ntawm lub teeb pom kev zoo uas tshwm sim thaum lub teeb pom kev zoo siv rau lub sijhawm ntev, thiaj li hloov cov kev kawm teeb pom kev zoo hauv lub sijhawm.
Kev kawm teeb pom kev zoo, tsom rau cov teeb meem uas muaj nyob rau hauv kev kawm teeb pom kev zoo, tsim cov kev kawm teeb pom kev zoo, uas tuaj yeem ua tau raws li cov kev xav tau niaj hnub ntawm cov kws qhia ntawv thiab cov tub ntxhais kawm. Cov chav kawm teeb pom kev zoo yog tag nrho cov hlau kub dissipation, lub teeb yuag, siab CRI, tsis muaj stroboscopic, xiav lub teeb mus txog RG0, thiab tseem muaj qhov tseem ceeb tshaj UGR<15 anti-glare="" design,="" providing="" classroom="" lighting="" in="" all="" directions="" and="" angles.="">
