Dab tsi yog qhov zoo tshaj plaws hauv chav kawm LED qhov muag tiv thaiv teeb?
Raws li myopia ntawm cov tub ntxhais hluas hauv peb lub tebchaws dhau los ua mob hnyav, lub tebchaws tau them nyiaj ntau dua rau kev kho dua ntawm chav kawm teeb pom kev tiv thaiv qhov muag teeb. Muaj ntau ntau chav kawm qhov muag tiv thaiv teeb tsim khoom, yog li chav kawm qhov muag tiv thaiv teeb tsim hluav taws xob zoo dua, cia saib tam sim no. !
Benwei Teeb pom kev zoo ua raws cov qauv hauv tebchaws. Qhov nruab nrab lub teeb pom kev zoo ntawm lub desktop ntawm chav kawm teeb pom kev tiv thaiv teeb nyob hauv chav kawm: ≥300lx, qhov tsis sib xws ntawm chav kawm teeb pom kev zoo (Uo) ≥ 0.7, qhov nruab nrab qhov pom kev zoo ntawm blackboard ≥ 500lx, qhov tsis sib xws ntawm blackboard teeb pom kev zoo (Uo) ≥ 0.8 , glare tus nqi (UGR)) ≤16 Lub teeb ci, qhov ntsuas xim xim (Ra) ≥80, xim kub (CCT) 3000K-5500K.
Benwei teeb pom kev zoo LED qhov muag tiv thaiv chav kawm teeb blackboard teeb zoo tom qab hloov:
(1) Kev txuag hluav taws xob: LED qhov muag tiv thaiv teeb siv LED lub teeb pom kev muaj lub zog qis thiab ua haujlwm tau zoo. Feem ntau, 3/4W lub zog hluav taws xob LED teeb tau piv rau cov teeb rooj ib txwm muaj, thiab lawv qhov ci thiab qhov dav tau tsim nyog rau kev nyeem thiab kawm. Vim tias qhov ua tau zoo tshaj plaws hloov pauv hluav taws xob zoo ntawm LED qhov muag tiv thaiv teeb, lub zog siv hluav taws xob feem ntau tsuas yog ib zaug hauv 150 teev, uas muaj cov khoom siv txuag hluav taws xob zoo heev.
(2) Kev tiv thaiv ib puag ncig: LED teeb tiv thaiv qhov muag yog ua los ntawm cov khoom tsis muaj tshuaj lom. Cov teeb roj fluorescent ib txwm tuaj yeem ua rau muaj kuab paug nrog mercury, thiab LEDs kuj tseem tuaj yeem siv dua thiab rov siv dua yam tsis muaj kuab paug. Piv nrog rau lub teeb tso tawm los ntawm cov teeb txawb ib txwm, LED qhov muag tiv thaiv lub teeb tsis muaj cua sov thiab ultraviolet rays nyob hauv qhov pom kev, tsis muaj hluav taws xob, tiv thaiv qhov ci, lub teeb txias, thiab tuaj yeem kov tau ncaj qha. Nws yog lub ntsuab tshiab, tsis muaj kuab paug, thiab tsis muaj hluav taws xob zoo ib puag ncig teeb pom kev zoo.
(3) Ntev: Raws li kev xav, LED teeb lub teeb thiab LED qhov muag tiv thaiv lub teeb tuaj yeem siv tau yam tsis hloov qhov muag teeb rau 10 xyoo, uas yog 80-100 npaug ntawm qhov muag qhov muag. Tau kawg, lub neej tiag tiag yuav txawv me ntsis, tab sis nws lub neej ua haujlwm ntev dua li lwm qhov muag teev. Teeb meem.
(4) Kev Noj Qab Haus Huv: Lub teeb ci tsis muaj cov tshuaj hnyav hnyav xws li tungsten thiab mercury. Cov khoom siv hluav taws xob hluav taws xob tsis muaj cov tungsten filaments hauv cov roj teeb, lossis tsis muaj mercury hauv cov roj fluorescent thiab cov roj teeb txuag hluav taws xob.
(5) Kev Nyab Xeeb: Ib qho ntawm LED teeb tiv thaiv qhov muag siv 12V qis-voltage DC lub zog siv, thiab 36V yog qhov tsawg kawg nkaus uas tib neeg lub cev tuaj yeem hnov, thiab lub zog hluav taws xob tsawg dua 36V muaj kev nyab xeeb rau tib neeg lub cev. Qhov thib ob, lub teeb ci ntawm lub qhov muag tiv thaiv lub teeb pom kev zoo siv cov txheej txheem LED tshwj xeeb thiab tsis muaj cov iav tawg yooj yim, yog li nws muaj kev nyab xeeb dua thiab ntseeg tau siv.
(6) Kev Nyuaj Siab: LED qhov muag tiv thaiv lub teeb pom kev zoo siv DC lub zog, uas yuav tsis tsim lub teeb pom kev zoo ib yam thaum siv AC zog. Lub teeb tawm los ntawm LED qhov muag tiv thaiv lub teeb yog muag heev thiab tsis flicker. Tsis muaj qhov xav tsis thoob txawm tias koj saib ncaj qha rau nws. Txhawm rau ua kom tsis muaj stroboscopic, tsis muaj qhov pom kev, tsis muaj lub teeb ci ultraviolet yuav tsum yog LED qhov muag tiv thaiv teeb.
(7) Tiv thaiv qhov muag: Cov xim kub me ntsis siab dua yuav tsis ua rau tib neeg lub qhov muag, thiab yuav tsis muaj qhov muag mob thiab o thaum nyeem ntawv lossis ua haujlwm ntev. Ua ke nrog lub ntsiab lus thib rau, qhov no txo qis kev qaug zog ntawm tib neeg lub qhov muag.
