Cov kws tshawb fawb tau tsim lub teeb xaim xiav LED teeb

Raws li ib yam ntawm cov xim dawb lias, lub teeb xiav yog qhov muag pom nyob hauv ntau lub teeb. Txawm li cas los xij, feem ntau ntawm cov teeb ci LED tam sim no ntawm kev ua lag luam tawm lub teeb xiav los ntawm lub nti ua rau kom muaj siab muaj cov phosphor daj los kho qhov teeb pom kev dawb. Yog li ntawd, qhov teeb meem xiav teeb ntawm LED teeb ci nyob nruab nrab ntawm 400nm thiab 500nm yog qhov tshwj xeeb tshaj yog.

Cov kev tshawb fawb dhau los tau lees tias xiav lub teeb nrog nthwv dej ntawm 450 txog 500 nm tuaj yeem cuam tshuam cov khoom tsim tawm ntawm melatonin, yog li cuam tshuam qhov zoo ntawm peb hmo pw. Tam sim no, cov kws tshawb nrhiav tau txhim kho ib qho qauv LED. Lub LED txo cov xiav tivthaiv (hloov daim npog ntsej muag), txo qhov xiav tivthaiv, thiab tib lub sijhawm ua rau xim zoo li nws nyob hauv ntuj tshav ntuj. Cov kev tshawb fawb tau luam tawm nyob rau hauv phau ntawv journal ACS Cov Khoom Siv Khoom Siv& Muaj kev cuam tshuam.

Tus qauv tiv thaiv tuaj yeem ua rau lub teeb dawb dawb tsis muaj lub khaus xiav uas tuaj yeem ua teeb meem kev mob nkeeg

Raws li pov thawj ntawm lub tswv yim, cov kws tshawb nrhiav tau txheeb xyuas thiab coj los ua ib hom tshuaj fluorescent tshiab uas muaj ((Na1.92Eu0.04) MgPO4F). Hauv qhov ntsuas qhov thermal stability, cov xim tawm ntawm cov phosphor tseem nyob ntawm chav sov thiab qhov ua haujlwm siab dua (149.4 ° C) ntawm kev ua lag luam LED teeb pom kev zoo. Hauv kev ntsuas lub sij hawm ntev av noo, xim ntawm cov sib txuas los yog cov kev siv hluav taws xob tsis hloov.

Txhawm rau kom nkag siab tias cov khoom siv no ua haujlwm li cas, cov kws tshawb nrhiav tsim cov qauv tiv thaiv: ib lub teeb liab LED npog nrog ib lub hnab ntim silicone, uas muaj cov khoom sib xyaw ntawm xiav sib txuas, liab phosphors thiab phosphors ntsuab. Nws tsim tawm qhov yuav tsum tau muaj lub teeb sov dawb lub teeb dawb thaum txo qhov kev siv ntawm lub teeb hluav taws xob xiav, uas txawv ntawm kev lag luam LED qij. 8-

Cov kws tshawb nrhiav tau hais tias cov khoom siv kho qhov muag ntawm lub qauv tuaj yeem yuav luag tag nrho cov xim ntawm qhov khoom, xws li lub hnub ci ntuj, uas tuaj yeem ua tau raws li qhov xav tau ntawm cov teeb pom kev sab hauv, txawm hais tias lawv tau hais ntxiv tias yuav tsum tau ua haujlwm ntau dua ua ntej npaj rau kev siv txhua hnub.
