Thaum tshav kub kub dissipation: Lub Lifeline ntawm LED teeb pom kev zoo
LED chips yog kub heev -sensitive. Qhov kub siab ncaj qha ua rau:
Accelerated Lumen Depreciation: ceev brightness poob, ua tsis tau raws li lub neej nyob.
Spectral Shift: Hloov nyob rau hauv emitted lub teeb xim kub (xim).
Kev txo qis qis qis: Lub neej tseem ceeb luv luv los ntawm kaum tawm txhiab mus rau ntau txhiab teev.
Kev pheej hmoo ua tsis tiav: Cov khoom siv hluav taws xob ua rau muaj kev puas tsuaj nyob rau hauv qhov kub thiab txias.
Ib qho kev siv hluav taws xob zoo cua sov feem ntau suav nrog:
High thermal conductivity cov ntaub ntawv: Siv aluminium alloy (tsis yog yas) ua lub ntsiab cua sov lub cev. Aluminium lub siab thermal conductivity sai hloov tshav kub ntawm LED substrate.
Loj - cheeb tsam tshav kub dab dej fins: Ua kom thaj chaw saum npoo raug huab cua kom cov cua sov dissipation los ntawm ntuj convection los yog yuam cua txias.
Cov kiv cua ua kom txias txias: Qhov tseem ceeb rau siab - fais fab fixtures. Nyob ntsiag to, txhim khu kev qha, thiab plua plav- kiv cua tiv taus yog qhov tseem ceeb. Cov qauv tsim tau zoo ua kom muaj kev tswj xyuas ceev ceev raws li qhov kub thiab txias, ntsuas kub dissipation thiab suab nrov.
Cov khoom siv hluav taws xob sib txuas: Siab- cov roj thermal zoo lossis cov ntaub qhwv kom ntseeg tau tias muaj cua sov hloov ntawm LED nti thiab lub dab dej kub.
Ntsuam xyuas Thaum tshav kub kub Dissipation: Ua ntej yuav khoom, tshuaj xyuas cov tshuaj tiv thaiv kom nkag siab txog cov qauv cua sov. Thaum siv, kov lub vaj huam sib luag (tso tawm ntawm thaj chaw LED). Kev sov yog qhov qub; Thaum tshav kub kub heev qhia tias tsis txias txias.
Kev Siv Hluav Taws Xob: Tus nqi teeb pom kev zoo thiab Eco-Kev xaiv tus phooj ywg
Kev siv hluav taws xob ntsuas qhov ua tau zoo npaum li cas cov khoom siv hluav taws xob hloov hluav taws xob rau hauv lub teeb pom kev (tshwj xeeb tshaj yog cov hluav taws xob photosynthetically active radiation).
Tsom ntsoov rau "Luminous Efficacy": Qhov no yog hais txog lub luminous flux (lumens) los yog photosynthetic photon flux (PPF) uas tsim ib watt ntawm hluav taws xob. Cov nqi siab dua qhia tias kev txuag hluav taws xob ntau dua.
Ntev -Lub Sij Hawm Txuag Zog: Piv txwv tias 100W LED fixture muab qhov sib npaug lossis zoo dua PAR qhov tseem ceeb tshaj li 200W ib txwm siv, ua haujlwm 10 teev txhua hnub ntawm $ 0.15 ib kWh. Tshaj ib xyoos, kev txuag hluav taws xob ib leeg yog kwv yees li (200-100)W * 10h / hnub * 365 hnub / 1000 * $ 0.15 ≈ $ 54.75. Txuag tshaj qhov khoom siv lub neej yuav nyob deb tshaj qhov pib tus nqi yuav khoom sib txawv.
Kev Pabcuam Ib puag ncig: Txo kev siv hluav taws xob txhais tau tias muaj cov pa roj carbon tsawg dua.
