Nws tau tshaj tawm tias Tebchaws Meskas Lub Tsev Haujlwm Saib Xyuas Hluav Taws Xob (DOE) tsis ntev los no tau tshaj tawm tsab ntawv ceeb toom thib peb ntawm LED tsav tsheb kev ntseeg siab raws li kev ntsuas lub neej ntev ntev.Cov kws tshawb fawb ntawm Solid-state teeb pom kev zoo (SSL) ntawm Tebchaws Meskas Lub Tsev Haujlwm Saib Xyuas Lub Zog ntseeg tias cov txiaj ntsig tshiab tau lees paub qhov kev ntsuas nrawm nrawm (AST) txoj kev, uas tau pom tias muaj kev ua tau zoo nyob rau hauv ntau yam hnyav.Tsis tas li ntawd, cov txiaj ntsig kev xeem thiab ntsuas qhov ua tsis tau zoo tuaj yeem qhia cov neeg tsav tsheb ntawm cov tswv yim cuam tshuam los txhim kho kev ntseeg tau ntxiv.
Raws li paub zoo, LED tsav tsheb, zoo li cov khoom siv LED lawv tus kheej, yog qhov tseem ceeb rau lub teeb pom kev zoo.Kev tsim tus tsav tsheb tsim nyog tuaj yeem tshem tawm flicker thiab muab teeb pom kev zoo ib yam.Thiab tus tsav tsheb kuj yog qhov feem ntau yuav muaj nyob rau hauv LED teeb los yog teeb pom kev zoo fixtures rau malfunction.Tom qab paub txog qhov tseem ceeb ntawm cov neeg tsav tsheb, DOE tau pib qhov kev sim tsav tsheb mus sij hawm ntev hauv 2017. Qhov project no suav nrog ib qho channel thiab ntau tus tsav tsheb, uas tuaj yeem siv los kho cov cuab yeej xws li qab nthab grooves.
Lub Tsev Haujlwm Saib Xyuas Kev Ruaj Ntseg Hauv Tebchaws Meskas yav dhau los tau tshaj tawm ob tsab ntawv tshaj tawm txog cov txheej txheem xeem thiab kev ua tiav.Tam sim no nws yog daim ntawv tshaj tawm thib peb cov ntaub ntawv, uas suav nrog cov khoom kuaj tau ntawm 6000-7500 teev ntawm kev ua haujlwm raws li AST.
Qhov tseeb, kev lag luam tsis muaj sijhawm ntau los kuaj cov tsav tsheb hauv ib puag ncig kev ua haujlwm tau ntau xyoo.Ntawm qhov tsis sib xws, Tebchaws Meskas Lub Tsev Haujlwm Saib Xyuas Kev Ruaj Ntseg thiab nws tus neeg cog lus RTI International tau sim tus actuator hauv qhov lawv hu ua 7575 ib puag ncig - cov av noo hauv tsev thiab qhov kub thiab txias tau khaws cia ntawm 75 ° C. Qhov kev sim no suav nrog ob theem ntawm kev sim tsav tsheb, ywj siab ntawm lub channel.Ib theem tsim nqi tsawg dua, tab sis nws tsis muaj qhov sib cais uas thawj zaug hloov AC rau DC thiab tom qab ntawd tswj cov tam sim no, uas yog qhov tshwj xeeb rau ob-theem tsim.
Lub Tsev Haujlwm Saib Xyuas Kev Ruaj Ntseg Hauv Tebchaws Meskas tau tshaj tawm tias hauv kev sim ntawm 11 qhov sib txawv, txhua qhov tsav tau khiav mus txog 1000 teev hauv 7575 ib puag ncig.Thaum tsav tsheb nyob rau hauv ib puag ncig ib puag ncig, LED load txuas nrog lub tsav yog nyob rau hauv ib puag ncig sab nraum zoov, yog li AST ib puag ncig tsuas cuam tshuam rau tsav.DOE tsis koom nrog lub sijhawm ua haujlwm raws li AST cov xwm txheej nrog lub sijhawm ua haujlwm nyob rau hauv ib puag ncig ib puag ncig.Thawj pawg ntawm cov cuab yeej ua tsis tiav tom qab 1250 teev ntawm kev ua haujlwm, txawm hais tias qee cov khoom siv tseem ua haujlwm.Tom qab kev sim rau 4800 teev, 64% ntawm cov cuab yeej ua tsis tiav.Txawm li cas los xij, xav txog qhov kev sim hnyav ib puag ncig, cov txiaj ntsig no twb zoo heev.
Cov kws tshawb fawb tau pom tias feem ntau qhov ua yuam kev tshwm sim hauv thawj theem ntawm tus neeg tsav tsheb, tshwj xeeb tshaj yog nyob rau hauv lub hwj chim kho kom raug (PFC) thiab electromagnetic cuam tshuam (EMI) hluav taws xob hluav taws xob hluav taws xob.Hauv ob theem ntawm tus neeg tsav tsheb, MOSFETs kuj muaj qhov tsis raug.Ntxiv rau qhov qhia meej txog thaj chaw xws li PFC thiab MOSFET uas tuaj yeem txhim kho tus qauv tsav tsheb, AST no kuj qhia tau tias kev ua txhaum feem ntau tuaj yeem kwv yees raws li kev saib xyuas kev ua haujlwm ntawm tus tsav tsheb.Piv txwv li, kev saib xyuas lub zog thiab qhov hluav taws xob tam sim no tuaj yeem tshawb pom qhov ua txhaum ntxov ua ntej.Qhov nce hauv flashing kuj qhia tau tias muaj kev ua haujlwm tsis zoo yog yuav tshwm sim.
Tau ntev, DOE's SSL txoj haujlwm tau ua qhov kev sim thiab tshawb fawb tseem ceeb hauv SSL teb, suav nrog cov ntawv thov scenario cov khoom kuaj nyob rau hauv Gateway project thiab cov khoom lag luam kuaj kev ua tau zoo raws li Caliper project.
