Yuav ua li cas LED qhov muag tiv thaiv chav kawm teeb teeb txhawb chav kawm hloov pauv
Cov teeb pom kev hauv chav kawm muaj kev cuam tshuam loj rau kev noj qab haus huv ntawm cov tub ntxhais hluas. Nrog kev nce qib ntawm myopia, kev saib xyuas kev noj qab haus huv ntawm cov tub ntxhais hluas tau txais kev saib xyuas dav los ntawm zej zog thiab tsoomfwv cov haujlwm.
Ib qho ntxiv, kev txhim kho txuas ntxiv thiab txhim kho kev tshawb fawb ntawm LED teeb pom kev zoo thev naus laus zis tau muab ntau lub tswv yim thiab kev daws teeb meem rau chav teeb pom kev zoo. Yog li ntawd, chav kawm teeb pom kev zoo tsis tsuas yog ua tau raws li qhov xav tau teeb pom kev zoo, tab sis kuj zoo dua thiab nyab xeeb dua. Hais txog qhov pom kev, muaj peev xwm pom tau meej thiab tsis nkees yog qhov tseem ceeb ntawm kev teeb pom kev hauv chav kawm.
Ib puag ncig teeb pom kev zoo ntawm ntau chav kawm hauv tsev kawm ntawv hauv peb lub tebchaws siv cov teeb roj fluorescent yooj yim, feem ntau yog cov teeb liab qab yam tsis muaj lub hau npog. Ib puag ncig teeb pom kev zoo ntawm chav kawm yog qhov tsis zoo:
1. Cov teeb pom kev zoo ib yam thiab qhov pom kev zoo feem ntau qis dua li lub tebchaws cov qauv. Tus qauv qhov tseem ceeb ntawm cov teeb pom kev zoo hauv chav kawm yog siab dua 300LX thiab siab dua 0.7, thaum lub teeb pom kev zoo thiab tsis sib xws ntawm cov raj fluorescent tsis tuaj yeem txaus siab. Yog tias cov tub ntxhais kawm nyob rau qhov tsis pom kev zoo thiab tsis pom kev ntev ntev Kev kawm nyob rau hauv ib puag ncig lub teeb uas tsis zoo ib yam tuaj yeem ua rau pom kev qaug zog.
Qhov thib ob, cov blackboards hauv chav kawm feem ntau tsis muaj cov teeb duab tshwj xeeb hauv chav kawm ntawv. Cov tub ntxhais kawm tsis tuaj yeem pom meej, muaj teeb meem mloog zoo, thiab nquag pom kev nkees, ua rau myopia.
Peb, cov teeb roj fluorescent feem ntau yog nruab nrog cov khoom siv hluav taws xob, thiab qhov flicker yog qhov hnyav. Txhawm rau hloov kho rau qhov hloov pauv ntau zaus, tus tub ntxhais kawm' qhov muag pom kev yuav raug kho ntau dhau, ua rau pom kev nkees. Cov teeb tiv thaiv qhov muag tam sim no yuav tsum tsis muaj qhov muag.
Qhov thib plaub, lub raj roj fluorescent, xim kub siab dhau, feem ntau siab dua 6000K, vim tias lub teeb xim dawb dhau, thiab lub teeb xiav tiv thaiv ntau dhau, nws yooj yim ua rau cov tub ntxhais kawm zoo siab, ua rau lub qhov muag qaug zog, txawm tias ua rau tsis tsaug zog, ua phem kev noj qab haus huv ntawm lub cev thiab lub hlwb, chav kawm ib txwm tiv thaiv qhov muag Cov xim kub yuav tsum tau tswj ntawm 3500K-5500K, ze rau lub teeb ntuj, sov thiab xis nyob.
Tam sim no, tsoomfwv thiab cov tsev kawm ntawv tau maj mam nkag siab qhov tseem ceeb ntawm kev teeb pom kev zoo hauv tsev kawm ntawv rau cov tub ntxhais kawm ntawv qhov muag pom, thiab tau pib ua haujlwm txhim kho teeb pom kev zoo, siv tus qauv LED qhov muag tiv thaiv chav kawm teeb thiab LED teeb tiv thaiv blackboard teeb los txhim kho teeb pom kev zoo ib puag ncig ntawm cov chav kawm hauv tsev kawm ntawv. Ua kom nrov-saib xyuas qhov zoo hauv chav kawm ib puag ncig teeb pom kev zoo los tiv thaiv kev noj qab haus huv ntawm cov tub ntxhais hluas'
Tus txheej txheem lossis tsis ua raws ntawm lub tsev kawm ntawv teeb pom kev zoo ib puag ncig cuam tshuam rau cov menyuam kawm ntawv qhov muag pom. Qhov zoo ntawm chav tiv thaiv qhov muag teeb nyob rau ntawm kev ua lag luam tsis sib xws, tab sis LED qhov muag tiv thaiv chav kawm teeb uas tsim los ntawm Benwei Teeb pom kev zoo sawv ntawm ntau chav teeb hauv chav kawm! Raws li lub tsev kawm ntawv noj qab haus huv teeb pom kev zoo Implementer. LED qhov muag tiv thaiv chav kawm teeb tsim los ntawm Benwei Teeb pom kev zoo muaj cov hauv qab no:
1. Cov teeb pom kev zoo tshaj plaws thiab kev ua kom pom kev zoo ib yam: Raws li lub teb chaws tus qauv GB7798-2010, cov chav kawm hauv chav kawm tswj cov teeb pom kev zoo flat300, kev teeb pom kev zoo ib yam ≥0.7, blackboard tuav qhov nruab nrab qhov pom kev zoo ≥500, thiab kev teeb pom kev zoo ib yam ≥0.8. Raws li qhov kawg ntawm xyoo 2018, ntau dua 90% ntawm qhov pom kev zoo thiab tsis sib xws ntawm txhua chav kawm teeb nyob hauv 1,000 lub tsev kawm ntawv theem pib thiab theem ob uas peb tau kho dua tshiab tsis tau raws li cov qauv hauv tebchaws. Txawm tias qhov pom kev ntawm qee lub tsev kawm ntawv lub rooj thiab cov ntawv dub tsuas yog ntau dua 100 lux. Cov tub ntxhais kawm kawm nyob rau ib puag ncig lub teeb pom kev ntev ntev tuaj yeem ua rau pom kev qaug zog thiab ua rau muaj qhov muag.
2. Anti-glare: Lub teb chaws tus qauv teev tseg tias qhov ci ntawm chav teeb pom kev zoo yog< 19,="" thiab="" tsev="" kawm="" ntawv="" feem="" ntau="" teeb="" pom="" kev="" zoo="" siv="" cov="" teeb="" ci="" teeb="" ci="" yooj="" yim,="" lub="" teeb="" pom="" kev="" ncaj="" qha,="" lub="" teeb="" zoo="" nkauj="" heev,="" thiab="" tus="" nqi="" glare="" tshaj="" 22.="" yog="" li="" ntawd,="" cov="" leeg="" ntawm="" lub="" qhov="" muag="" nruj="" heev,="" uas="" cuam="" tshuam="" loj="" heev="" rau="" cov="" tub="" ntxhais="" kawm'="" muaj="" peev="" xwm="" mloog="" zoo="" hauv="" chav="">
3. Feem ntau, cov teeb roj fluorescent siv AC lub zog, qhov hloov pauv tam sim no nrog lub sijhawm, thiab 100 flickers ib pliag, ua rau lub teeb ci tsis ruaj khov. Thaum kawm nyob rau hauv qhov chaw stroboscopic lub teeb pom kev, lub kaw lus yuav tsum tau hloov kho qhov loj ntawm cov menyuam kawm ntawv qhov muag. Tiv thaiv kev ruaj ntseg ntawm lub teeb pom kev zoo thiab qhov ntse ntawm daim duab. Kev kawm nyob rau ib puag ncig lub teeb pom kev no ntev yuav ua rau cov menyuam kawm ntawv lub cev tsis muaj zog vim siv ntau dhau.
4. Kev tiv thaiv lub teeb xiav thiab lwm yam teeb meem kev phom sij: Qhov ua kom luv-nthwv dej xiav lub teeb nruab nrab ntawm 400-500nm hauv cov teeb pom kev zoo ib yam LED tuaj yeem ua rau tsis pom kev puas tsuaj rau lub qhov muag, xws li kev tsim myopia, mus rau thaj tsam kab mob macular uas ncaj qha nkag mus rau lub qhov muag mus rau lub fundus. Ntxiv nrog rau qhov teeb meem xiav lub teeb nyob rau hauv ib txwm LEDs, muaj xya qhov teeb meem teeb meem xws li actinic ultraviolet, ze ultraviolet, kub hauv qhov muag, tsis pom kev tsis pom kev, qhov chaw me me, thiab hluav taws xob tawg. 7 yam teeb pom kev zoo no ua rau peb lub qhov muag thiab lub cev sib txawv.
5. Kev tiv thaiv lub teeb tsis zoo thiab ua haujlwm lub neej ntev: Cov teeb pom kev zoo yuav muaj lub teeb pom kev hnyav tom qab ib nrab xyoo ntawm kev siv, ua rau txo qis hauv cov teeb pom kev zoo, uas yuav tsis ua tau raws li lub teb chaws tus qauv qis. Tam sim no, txhawm rau tswj hwm lub teeb pom kev zoo uas ua tau raws li tus txheej txheem hauv tebchaws, kev hloov pauv lub teeb Nws yuav siv sijhawm 2 txog 6 lub hlis thiab xav tau kev saib xyuas mus sij hawm ntev los ntawm cov neeg ua haujlwm saib xyuas uas tsim nyog, ua rau cov nqi saib xyuas siab thiab pov tseg cov peev txheej.
6. Kev ntsuas xim zoo tshaj plaws: qhov pom ntawm cov teeb pom kev zoo ib yam tsis tiav, ua rau cov xim ploj thiab pov xim. Nyob deb ntawm kev ncav cuag lub tebchaws tus qauv Ra≥80, thiab cov xim tsis zoo tsim muaj peev xwm ntawm cov teeb pom kev zoo yuav cuam tshuam ncaj qha rau menyuam' kev muaj peev xwm ntxub ntxaug xim.
7. Cov xim sov kom xis nyob: Lub teb chaws tus qauv teev tseg tias xim kub yog 3300-5300K, thiab qhov ntsuas tiag tiag nce mus txog 6500K. Cov xim kub dhau dhau yuav ua rau muaj kev faib ua feem ntawm cov hluav taws xob xiav, thiab lub teeb xiav tseem yuav nce ntxiv. Lub teeb xiav yuav ua rau hnyav zuj zus vim yog noob caj noob ces, ib puag ncig kev noj zaub mov zoo, kev noj qab haus huv thiab lub hnub nyoog Muaj teeb meem cuam tshuam los ntawm kev puas tsuaj ntawm macular. Kev kawm tus kheej lig rau lub sijhawm tseem yuav cuam tshuam rau kev zais melatonin hauv cov tub ntxhais kawm, txo kev pw tsaug zog zoo, thiab cuam tshuam rau kev kawm tau zoo ntawm hnub tom ntej.
8. Tiv thaiv qhov muaj feem cuam tshuam ntawm cov teeb roj fluorescent: cov roj fluorescent muaj mercury, phosphors thiab lwm yam tshuaj hnyav hlau. Yog tias mercury thiab cov hlau hnyav phosphors khaws tsis raug thiab pov tseg, lawv tseem yuav ua rau muaj kev phom sij loj rau ib puag ncig ib puag ncig. Lawv tuaj yeem nkag mus rau hauv ecology ntau yam. Ib puag ncig ncaj qha ua paug av, huab cua thiab dej. Tom qab ntawd nkag mus rau tib neeg lub cev los ntawm cov saw zaub mov, cuam tshuam rau tib neeg kev noj qab haus huv, thiab kev ua kom pom kev zoo ntawm cov teeb roj fluorescent tsawg, feem ntau cov teeb fluorescent tsuas yog 50lm/w. Txawm hais tias lub teeb fluorescent tso lub teeb ntawm 365 degrees, lub teeb tawm hauv qhov kev coj rov qab yog qhov tsis muaj txiaj ntsig. Txawm hais tias nws tau rov qab los ntawm lub teeb txawb, qhov ua tau zoo ntawm kev ua haujlwm qis thiab siv lub zog siab dhau. Cov ballasts hauv cov teeb roj fluorescent kuj tseem tso tawm cov suab tsis zoo uas muaj teeb meem rau lub cev.
