Lub teeb siv, LED xim kub thiab flash zaus ntawm cov chav kawm feem ntau tsis ua raws li lub teb chaws tus qauv
Classroom lighting should not only be "bright", but "standard", which is what Gu Lin insisted. "Classroom lighting has relevant national policies, such as the "Classroom Lighting and Lighting Hygiene Standards for Primary and Secondary Schools", but during the construction and acceptance of school buildings, classroom lighting does not have to be compelled to meet the standards like firefighting and sewage discharge. In fact, if the classroom lighting Failure to meet the standard will greatly affect the students' eyesight.
LED kev kawm teeb pom kev lag luam pom tias chav kawm teeb pom kev zoo ib puag ncig tsis yog raws li tus qauv feem ntau hauv cov ntsiab lus hauv qab no:
Lub illuminance thiab illuminance uniformity ntawm lub rooj yog feem ntau qis dua lub teb chaws tus qauv (lub teb chaws tus qauv: lub illuminance ntawm lub rooj yuav tsum siab tshaj 300 lux, thiab lub illuminance uniformity yog ntau tshaj 0.7). Txawm li cas los xij, yog tias cov tub ntxhais kawm nyob rau lub teeb pom kev tsis zoo rau lub sijhawm ntev, thiab lub teeb pom kev tau txais los ntawm cov rooj sib txawv hauv tib chav kawm tsis zoo ib yam, qee cov tub ntxhais kawm yuav nyuaj rau kev nyeem, nyeem thiab sau, uas yuav ua rau pom kev qaug zog.
At the same time, a point that is often overlooked is that most classrooms use ordinary bracket lamps installed in front of the blackboard as blackboard lamps, and no special blackboard lamps are used, or even blackboard lighting is not arranged, resulting in the average blackboard illumination far lower than the national standard (national standard: blackboard illumination Greater than or equal to 500 lux, the uniformity is greater than 0.8), some students can't see the text on the blackboard, and they are prone to visual fatigue and myopia.
Most of the classrooms are directly installed with exposed fluorescent tubes. The light directly hits the students' eyes and produces glare, which distracts the students' attention, reduces the learning efficiency, causes visual fatigue, and induces myopia. In addition, fluorescent lamps are generally equipped with magnetic ballasts, which have serious optical stroboscopic effects. In order to adapt to frequency changes, students' visual systems will frequently adjust themselves, causing visual fatigue.
Tsis tshua muaj xim rendering Performance index kuj yog ib qho tsis zoo ntawm chav kawm teeb pom kev zoo. Cov chav kawm feem ntau siv cov teeb fluorescent nrog cov xim rendering Performance index ntawm ib ncig ntawm 70 (lub teb chaws tus qauv: xim rendering Performance index ntawm lub teeb qhov chaw yuav tsum tsis txhob tsawg tshaj li 80), ua rau cov xim distortion, tshwj xeeb tshaj yog nyob rau hauv kos duab, chemistry, handcraft xws li cov chav kawm ntawv, Nws cuam tshuam qhov kev txiav txim siab ntawm cov xim ntawm cov khoom, kom cov khoom tsis tuaj yeem nthuav tawm nws cov xim tiag tiag, thiab dhau sijhawm yuav ua rau pom teeb meem xws li qhov muag tsis pom xim thiab xim tsis muaj zog.
Tsis tas li ntawd, cov chav kawm feem ntau siv cov xim kub kub (6500K) fluorescent tubes (tus qauv hauv tebchaws: cov chav kawm yuav tsum siv 3300-5500K xim kub qhov chaw), uas muaj teeb meem xiav xiav, lub teeb xiav yuav ua rau muaj kev puas tsuaj rau lub retina, thiab tsis pom kev. txaus ntshai heev. Cov xim kub kub tuaj yeem ua rau cov menyuam kawm ntawv zoo siab thiab nkees yooj yim vim lub teeb xim dawb dhau.
