Ib qho ntxiv, lawv tsis ua tib zoo saib xyuas qhov muag, uas tuaj yeem ua rau myopia yooj yim.
2. Glare: Qee chav kawm raug teeb tsa ncaj qha nrog cov raj ci ci. Thaum cov tub ntxhais kawm tab tom saib daim txiag ntoo, lawv raug cuam tshuam los ntawm lub teeb ci ncaj qha los ntawm lub teeb, uas ua rau nws nyuaj rau mloog lus, uas txo qis kev kawm tau zoo thiab nquag pom kev nkees, uas tuaj yeem ua rau myopia mus sij hawm ntev.
3. Lub teeb xiav: Feem ntau hauv chav kawm feem ntau siv cov xim kub (6500k) cov raj roj fluorescent. Vim tias lub teeb xim dawb dhau thiab muaj ntau lub teeb xiav lub ntsej muag, nws yooj yim ua rau tsis muaj zog, qaug zog, thiab txawm tias tsis tsaug zog.
Chav kawm LED qhov muag tiv thaiv teeb tsim los ntawm Benwei Teeb pom kev zoo yog cov khoom lag luam nyab xeeb ntawm cov khoom siv hluav taws xob. Ntxiv rau kev tiv thaiv kev pom kev, lub teeb tiv thaiv qhov muag muaj qhov zoo dua li cov teeb pom kev zoo hauv lwm yam!
Ib, kev tiv thaiv ib puag ncig
Vim tias kev hloov pauv hluav taws xob siab ntawm LED qhov muag tiv thaiv teeb pom kev zoo hauv chav kawm, kev siv hluav taws xob tsuas yog ib zaug txhua 150 teev, uas muaj lub zog txuag hluav taws xob zoo. Hauv kev tshawb xav, LED qhov muag tiv thaiv lub teeb tuaj yeem siv tau 10 xyoo yam tsis hloov lub teeb, uas yog 80-100 zaug ntawm qhov muag qhov muag, thiab lub neej ua haujlwm ntev dua li lwm qhov muag.
Hais txog kev tiv thaiv ib puag ncig, chav kawm coj lub teeb tiv thaiv qhov muag yog ua los ntawm cov khoom tsis muaj tshuaj lom. Ib txwm muaj cov kua roj fluorescent tuaj yeem ua rau muaj kuab paug, thiab cov teeb LED kuj tseem tuaj yeem siv tau yam tsis muaj kuab paug. Piv nrog rau lub teeb uas tso tawm los ntawm lub teeb rooj ib txwm muaj, tsis muaj ultraviolet thiab hluav taws xob nyob hauv qhov pom ntawm LED qhov muag tiv thaiv teeb nyob hauv chav kawm. Nws tuaj yeem kov tau ncaj qha thiab nyab xeeb. Nws yog ntsuab, tsis muaj kuab paug, thiab tsis muaj hluav taws xob ib puag ncig teeb pom kev zoo.
Qhov thib ob, tiv thaiv qhov muag
Chav kawm LED qhov muag tiv thaiv lub teeb pom kev zoo siv DC lub zog hluav taws xob thiab yuav tsis tsim hluav taws xob stroboscopic. Lub teeb tawm los ntawm LED qhov muag tiv thaiv teeb nyob hauv chav kawm yog muag muag heev, thiab nws tuaj yeem ua tiav tiag tiag tsis muaj qhov muag thiab tsis muaj qhov ci. Nyob rau tib lub sijhawm, LED teeb siv xim xim me ntsis siab dua, uas yuav tsis ua rau tib neeg qhov muag pom. Ntev nyeem ntawv lossis ua haujlwm ntev yuav tsis ua rau mob qhov muag thiab o.
Kev Nyab Xeeb
Rau chav kawm ib puag ncig, kev nyab xeeb ntawm teeb pom kev yog qhov tseem ceeb heev. Led qhov muag tiv thaiv teeb nyob hauv chav kawm siv 12V qhov hluav taws xob DC qhov hluav taws xob qis, thiab 36V yog qhov hluav taws xob qis uas tib neeg lub cev tuaj yeem hnov. Lub zog hluav taws xob tsawg dua 36V muaj kev nyab xeeb rau tib neeg lub cev. Ib qho ntxiv, LED qhov muag tiv thaiv lub teeb pom kev zoo siv thev naus laus zis tshwj xeeb, tsis muaj qhov iav tawg yooj yim, thiab nws muaj kev nyab xeeb dua thiab ntseeg tau siv.
