Raws li kev tshaj tawm xov xwm, US Department of Energy (DOE) tsis ntev los no tau tshaj tawm nws qhov kev ntseeg thib peb ntawm LED tsav raws li kev ntsuas lub neej ntev ntev. Cov kws tshawb fawb ntawm US Department of Energy's Solid State Lighting (SSL) ntseeg hais tias cov txiaj ntsig tshiab tshaj tawm tau lees paub tias Kev Ntsuas Kev Ntsuas Kev Nyuaj Siab (AST) tau pom qhov ua tau zoo nyob rau hauv ntau yam mob 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 kev pom lub teeb zoo. Tus tsav tsheb tsim nyog tuaj yeem tshem tawm flickering thiab muab teeb pom kev zoo ib yam. Thiab tus neeg 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 kev sim thiab kev ua tiav, thiab tam sim no daim ntawv tshaj tawm thib peb cov ntaub ntawv xeem tau raug tso tawm, uas suav nrog cov txiaj ntsig ntawm cov khoom lag luam khiav hauv AST cov xwm txheej rau 6000-7500 teev.
Qhov tseeb, kev lag luam tsis muaj sijhawm ntau npaum li kev sim tsav hauv ib puag ncig kev ua haujlwm tau ntau xyoo. Ntawm qhov tsis sib xws, US Department of Energy thiab nws tus neeg cog lus RTI International tau sim tsav tsheb hauv qhov lawv hu ua 7575 ib puag ncig - nrog cov av noo hauv tsev thiab qhov kub thiab txias tsis tu ncua ntawm 75 ° C. Qhov kev sim no suav nrog ob theem ntawm kev sim tsav tsheb, ywj siab ntawm cov 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.

Tsoomfwv Meskas Lub Tsev Haujlwm Saib Xyuas Kev Ruaj Ntseg tau hais tias hauv kev sim ua rau 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 chav, 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 txuas lub sijhawm ua haujlwm raws li AST cov xwm txheej rau lub sijhawm ua haujlwm raws li ib txwm muaj. Thawj pawg ntawm cov cuab yeej ua tsis tiav tom qab ua haujlwm rau 1250 teev, txawm 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 txog thaj chaw xws li PFC thiab MOSFET uas tuaj yeem txhim kho tus qauv tsav tsheb, qhov 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. Ib qho kev nce hauv flashing kuj qhia tau tias kev ua haujlwm tsis zoo 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.
