Dhipatimendi reMagetsi reUS (DOE) ichangobva kuburitsa mushumo waro wechitatu wekuvimbika pane vatyairi ve LED zvichibva pakuedza kwenguva refu kwehupenyu.Vatsvagiri kubva kuUS department reEnergy's Solid State Lighting (SSL) vanotenda kuti zvichangobva kubuda zvinosimbisa mashandiro akanaka eiyo Accelerated Pressure Test (AST) pasi pemamiriro akasiyana siyana.Pamusoro pezvo, mhedzisiro yebvunzo uye kuyerwa kukundikana zvinhu zvinogona kuzivisa vatyairi vanogadzira nzira dzakakodzera dzekuwedzera kuvimbika.

Sezvinozivikanwa, vatyairi ve LED, sengeLED zvinoumba ivo pachavo, akakosha pamhando yemwenje yakakwana.Iyo yakakodzera mutyairi dhizaini inogona kubvisa flicker uye inopa yunifomu mwenje.Uye mutyairi ndiye zvakare angangoita chikamu mukatiMwenje dze LEDkana zvigadziriso zvemwenje kuti zvisashande.Mushure mekuona kukosha kwevatyairi, DOE yakatanga chirongwa chekuongorora mutyairi kwenguva refu muna 2017. Iyi purogiramu inosanganisira imwe nzira uye madhiraivha akawanda, ayo anogona kushandiswa kugadzirisa zvigadzirwa zvakadai seceiling grooves.

Dhipatimendi reMagetsi reUS rakamboburitsa mishumo miviri pamusoro pekuyedzwa uye kufambira mberi, uye ikozvino ndiyo yechitatu bvunzo data mushumo, iyo inovhara chigadzirwa chekuongorora mhedzisiro inomhanya pasi peAST mamiriro e6000 kusvika 7500 maawa.

Muchokwadi, iyo indasitiri haina nguva yakawanda yekuyedza madhiraivha munzvimbo dzakajairika dzekushanda kwemakore mazhinji.Kusiyana neizvi, Dhipatimendi reMagetsi reUnited States pamwe nekambani yeRTI International vakaedza dhiraivha mune yavanodaidza kuti 7575 nharaunda - zvese hunyoro hwemukati uye tembiricha zvinoramba zvichichengetwa pa75 ° C. Muedzo uyu unosanganisira matanho maviri ekuedzwa kwemutyairi, pasina chiteshi.Single stage design inodhura zvishoma, asi inoshaya dunhu rakaparadzana rinotanga kushandura AC kuenda kuDC yobva yadzora yazvino, iyo yakasarudzika kune maviri-matanho dhizaini.

Dhipatimendi reMagetsi reUS rakashuma kuti mubvunzo dzakaitwa pamadhiraivha gumi nerimwe akasiyana, madhiraivha ese akashandiswa munzvimbo ye7575 kwemaawa zana.Kana dhiraivha iri mukamuri yezvakatipoteredza, iyo LED mutoro wakabatana nedhiraivha unowanikwa pasi pekunze kwemamiriro ekunze, saka iyo AST nharaunda inongobata drive.DOE haina kubatanidza nguva yekushanda pasi peAST mamiriro nenguva yekushanda pasi pemamiriro ezvinhu.Batch rekutanga remidziyo rakakundikana mushure memaawa 1250 ekushanda, kunyangwe mamwe maturusi achiri kushanda.Mushure mekuedza kwemaawa 4800, 64% yemidziyo yakundikana.Zvakadaro, tichifunga nezve hutsinye hwekuyedza nharaunda, idzi mhedzisiro dzatove dzakanaka.

Vatsvagiri vakaona kuti kukanganisa kwakawanda kunoitika padanho rekutanga remutyairi, kunyanya musimba rekugadzirisa zvinhu (PFC) uye electromagnetic interference (EMI) kudzvinyirira maseketi.Mumatanho ese ari maviri emutyairi, maMOSFET anewo zvikanganiso.Pamusoro pekutsanangura nzvimbo dzakaita sePFC neMOSFET dzinogona kuvandudza dhizaini yevatyairi, iyi AST inoratidzawo kuti kukanganisa kunowanzo fungirwa zvichienderana nekutarisa mashandiro emutyairi.Semuyenzaniso, yekutarisa simba chinhu uye surge ikozvino inogona kuona zvikanganiso zvekutanga pamberi.Kuwedzera kwekupenya kunoratidzawo kuti kusashanda kuri kuda kuitika.

Kwenguva yakareba, chirongwa cheDOE's SSL chave kuita bvunzo dzakakosha uye tsvagiridzo mundima yeSSL, kusanganisira paGedhi.
