LED teeb pom kev tsis tuaj yeem xav txog xim kub xwb
Humans Factor In Lighting, tseem hu ua kev nplij siab teeb pom kev zoo, hais txog kev hloov kho teeb pom kev zoo thaum tib neeg ua haujlwm. Lub tswv yim teeb pom kev zoo no tau tshwm sim hauv Tebchaws Europe, txhawm rau tso cai rau tib neeg nyob hauv qhov chaw teeb pom kev zoo. LEDs yog qhov yooj yim-rau- tswj lub teeb pom kev zoo uas tuaj yeem hloov kho kom haum rau lub voj voog lom neeg, tab sis tseem xav tau kev faib spectral thiab xim kub.
Txawm hais tias illumination tsis yog tib yam cuam tshuam rau Circadian Rhythm, nws yog ib qho tseem ceeb. Qee cov kws tshawb fawb ntseeg tias teeb pom kev zoo tuaj yeem cuam tshuam rau tib neeg txoj kev xav, kev noj qab haus huv thiab lub zog.
LED pros thiab cons
Daim ntawv thov ntawm LED hauv tib neeg lub teeb pom kev muaj nws qhov zoo thiab qhov tsis zoo. Piv txwv li, lub teeb xiav belongs rau lub teeb txias dawb thiab ze rau lub teeb ntuj. Nws pab kom mloog zoo thiab tuaj yeem siv rau cov tub ntxhais kawm cov chav kawm thiab chaw ua haujlwm. Txawm li cas los xij, nws tseem yuav inhibit blackening thaum raug xiav lub teeb rau lub sijhawm ntev. Kev loj hlob ntawm melatonin cuam tshuam rau kev pw tsaug zog zoo, lub cev tsis muaj zog, thiab tej zaum yuav ua rau lub cev mob xws li mob qog noj ntshav.
Raws li kev tshawb fawb tshawb fawb, lub teeb xiav tuaj yeem tswj hwm cov tshuaj insulin, yog li yog tias nws raug lub teeb xiav ntev ntev thaum tsaus ntuj, nws yuav ua rau insulin tsis kam, uas txhais tau hais tias insulin txo qis thiab cov piam thaj hauv ntshav tsis tuaj yeem tswj tau, thiab qhov no. Qhov tshwm sim tuaj yeem ua rau rog rog, ntshav qab zib, thiab siab. Ntshav siab thiab lwm yam kab mob.
Kev tsim teeb pom kev tsis tuaj yeem xav txog xim kub xwb
Hauv kev tsim cov teeb pom kev zoo ntawm LED, qhov kev faib hluav taws xob spectral thiab xim kub yuav tsum raug xam tias yog ob qho tib si. Cov xim kub yog qhia nyob rau hauv qhov kub thiab txias K, sawv cev rau spectral Cheebtsam ntawm txawv lub teeb. Cov xim kub ntawm lub teeb xiav yog siab dua 5300K, uas belongs rau nruab nrab thiab siab xim kub thiab muaj lub siab kaj. Hloov pauv, lub teeb liab thiab lub teeb daj yog lub teeb xim sov, thiab xim kub yog qis dua 3300K, uas ua rau tib neeg sov so, noj qab haus huv thiab so, tsim nyog siv hauv tsev.
Txawm li cas los xij, nyob rau hauv tib cov xim kub kub, yuav muaj qhov sib txawv spectral distributions vim txawv cov neeg saib thiab lwm yam kev mob xws li huab cua thiab ib puag ncig. Yog li, cov kws tshawb fawb txog teeb pom kev zoo ntseeg tias Spectral Energy Distribution (SED) yog qhov tseem ceeb cuam tshuam rau tib neeg lub qhov muag thiab lub cev.
