UMnyango Wezamandla wase-US (i-DOE) usanda kukhipha umbiko wawo wesithathu onokwethenjelwa kubashayeli be-LED ngokusekelwe ekuhlolweni kwempilo okusheshisiwe kwesikhathi eside. Abacwaningi boMnyango Wezamandla Wase-US i-Solid State Lighting (SSL) bakholelwa ukuthi imiphumela yakamuva iqinisekisa ukusebenza okuhle kakhulu kwendlela ye-Accelerated Pressure Test (AST) ngaphansi kwezimo ezihlukahlukene ezinzima. Ngaphezu kwalokho, imiphumela yokuhlolwa kanye nezici zokwehluleka ezilinganisiwe zingazisa abathuthukisi babashayeli ngamasu afanelekile ukuze kuthuthukiswe ukwethembeka.

Njengoba kwaziwa, abashayeli be-LED, bathandaIzingxenye ze-LED ngokwazo, zibalulekile kwikhwalithi yokukhanya elungile. Idizayini efanelekile yomshayeli ingaqeda ukucwayiza futhi inikeze ukukhanya okufanayo. Futhi umshayeli uyingxenye okungenzeka kakhulu kuyoIzibani ze-LEDnoma izibani zokukhanyisa zingasebenzi kahle. Ngemva kokubona ukubaluleka kwabashayeli, i-DOE yaqala iphrojekthi yokuhlola abashayeli yesikhathi eside ngo-2017. Le phrojekthi ihlanganisa abashayeli besiteshi esisodwa kanye namashaneli amaningi, angasetshenziselwa ukulungisa izinto ezifana nemigodi ye-ceiling.

UMnyango Wezamandla wase-US ngaphambilini ukhiphe imibiko emibili ngenqubo yokuhlola nenqubekelaphambili, futhi manje sekuwumbiko wesithathu wokuhlola idatha, ohlanganisa imiphumela yokuhlolwa komkhiqizo osebenza ngaphansi kwezimo ze-AST amahora angu-6000 kuya kwangu-7500.

Eqinisweni, imboni ayinaso isikhathi esiningi sokuhlola ukushayela ezindaweni ezijwayelekile zokusebenza iminyaka eminingi. Ngokuphambene nalokho, uMnyango Wezamandla wase-US kanye nenkontileka yawo i-RTI International baye bahlola idrayivu kulokho abakubiza ngokuthi imvelo engu-7575 - kokubili umswakama wasendlini kanye nezinga lokushisa kugcinwa ngokungaguquki ku-75 ° C. Lokhu kuhlolwa kuhilela izigaba ezimbili zokuhlolwa komshayeli, ngaphandle kokuphazanyiswa. isiteshi. Idizayini yesiteji esisodwa ibiza kancane, kodwa ayinayo isekethe ehlukile eqale iguqule i-AC ibe yi-DC bese ilawula eyamanje, ehlukile ekwakhiweni kwezigaba ezimbili.

UMnyango Wezamandla wase-US ubike ukuthi ezivivinyweni ezenziwa kumadrayivu ahlukene ayi-11, wonke amadrayivu asetshenziswa endaweni engama-7575 amahora ayi-1000. Uma idrayivu itholakala ekamelweni lezemvelo, umthwalo we-LED oxhunywe ku-drive utholakala ngaphansi kwezimo zemvelo zangaphandle, ngakho-ke imvelo ye-AST ithinta kuphela idrayivu. I-DOE ayizange ihlobanise isikhathi sokusebenza ngaphansi kwezimo ze-AST nesikhathi sokusebenza ngaphansi kwezindawo ezivamile. Iqoqo lokuqala lamadivayisi lihlulekile ngemva kwamahora angu-1250 okusebenza, nakuba amanye amadivaysi asasebenza. Ngemva kokuhlola amahora angu-4800, u-64% wamadivayisi wehlulekile. Noma kunjalo, uma kucatshangelwa isimo sokuhlola esinzima, le miphumela isivele mihle kakhulu.

Abacwaningi bathole ukuthi amaphutha amaningi enzeka esigabeni sokuqala somshayeli, ikakhulukazi ku-power factor correction (PFC) kanye ne-electromagnetic interference (EMI) suppression circuits. Kuzo zombili izigaba zomshayeli, ama-MOSFET nawo anamaphutha. Ngaphezu kokucacisa izindawo ezifana ne-PFC ne-MOSFET ezingathuthukisa idizayini yomshayeli, le AST iphinde ibonise ukuthi amaphutha ngokuvamile angabikezelwa ngokusekelwe ekuqapheni ukusebenza komshayeli. Isibonelo, ukuqapha isici samandla kanye namandla okwandayo kungathola amaphutha kusenesikhathi. Ukwanda kombani futhi kukhombisa ukuthi ukungasebenzi kahle sekuzokwenzeka.

Sekuyisikhathi eside, uhlelo lwe-DOE lwe-SSL belwenza ukuhlola nokucwaninga okubalulekile emkhakheni we-SSL, kuhlanganise nase-Gateway.
