Zvinonzi United States Dhipatimendi reMagetsi (DOE) ichangobva kuburitsa yechitatu LED mutyairi kuvimbika mushumo wakavakirwa parefu-yakawedzera kukurumidza hupenyu bvunzo. Vatsvagiri veSolid-state lighting (SSL) yeUnited States Dhipatimendi reMagetsi vanotenda kuti mhedzisiro yazvino yakasimbisa accelerated pressure test (AST) nzira, iyo yakaratidza kuita kwakanaka pasi pemamiriro akasiyana-siyana akaomarara. Pamusoro pezvo, mhedzisiro yebvunzo uye kuyerwa kukundikana zvinhu zvinogona kuzivisa vatyairi vanogadzira nzira dzakakodzera dzekuwedzera kuvimbika.

Sezvinozivikanwa, madhiraivha e LED, senge ma LED ezvikamu ivo pachavo, akakosha kune yakakwana mhando yechiedza. Iyo yakakodzera mutyairi dhizaini inogona kubvisa flicker uye inopa yunifomu mwenje. Uye mutyairi ndiye zvakare angangoita chikamu mumwenje we LED kana zvigadziriso zvemwenje kusashanda. 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.

Bazi reUnited States reMagetsi rakamboburitsa mishumo miviri pamusoro pebvunzo uye kufambira mberi. Ikozvino ndiyo yechitatu bvunzo data repoti, iyo inosanganisira chigadzirwa bvunzo mhinduro dze6000-7500 maawa ekushanda pasi peAST mamiriro.

Muchokwadi, iyo indasitiri haina nguva yakawanda yekuyedza madhiraivha munzvimbo dzakajairika dzekushanda kwemakore mazhinji. Kusiyana neizvi, Dhipatimendi reMagetsi reUnited States nekambani yayo RTI International vakaedza actuator mune yavanodaidza kuti 7575 nharaunda - humidity yemukati uye tembiricha inochengetwa 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.

Bazi reUnited States reMagetsi rakashuma kuti mukuedzwa kwemadhiraivha gumi nerimwe akasiyana, madhiraivha ese akafamba kwemaawa 1000 munzvimbo ye7575. 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 yekutanga yemidziyo yakakundikana 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 tsvakiridzo mundima yeSSL, kusanganisira application mamiriro echigadzirwa bvunzo pasi peGateway purojekiti uye kutengeserana kwechigadzirwa bvunzo yekushanda pasi peCaliper chirongwa.
