Biravugwa ko Minisiteri ishinzwe ingufu muri Amerika (DOE) iherutse gushyira ahagaragara raporo ya gatatu ya LED yo kwizerwa ishingiye ku kizamini cy’ubuzima bwihuse. Abashakashatsi bo mu mucyo wa Leta (SSL) wo muri Minisiteri ishinzwe ingufu muri Leta zunze ubumwe z’Amerika bemeza ko ibisubizo biheruka kwemeza uburyo bwihuse bw’ikizamini cy’umuvuduko (AST), cyerekanye imikorere myiza mu bihe bitandukanye. Byongeye kandi, ibisubizo byikizamini hamwe nimpamvu zapimwe zatsinzwe zirashobora kumenyesha abashoferi ingamba zingirakamaro kugirango barusheho kunoza ubwizerwe.

Nkuko bizwi, abashoferi ba LED, nkibigize LED ubwabo, nibyingenzi kugirango urumuri rwiza. Igishushanyo mbonera gikwiye gishobora gukuraho flicker no gutanga itara rimwe. Kandi umushoferi kandi nikintu gishoboka cyane mumatara ya LED cyangwa amatara yo gukora nabi. Nyuma yo kubona akamaro k'abashoferi, DOE yatangiye umushinga muremure wo kugerageza abashoferi muri 2017. Uyu mushinga urimo umuyoboro umwe hamwe nabashoferi benshi, ushobora gukoreshwa mugukosora ibikoresho nkibisenge bya sima.

Minisiteri ishinzwe ingufu muri Leta zunze ubumwe z’Amerika yasohoye raporo ebyiri ku bijyanye n’ibizamini ndetse n’iterambere. Ubu ni raporo ya gatatu yikizamini cya raporo, ikubiyemo ibisubizo byibizamini byibicuruzwa byamasaha 6000-7500 yo gukora mubihe AST.

Mubyukuri, inganda ntizifite umwanya munini wo kugerageza drives ahantu hasanzwe ikora mumyaka myinshi. Ibinyuranye na byo, Minisiteri y’ingufu muri Leta zunze ubumwe z’Amerika hamwe n’umushinga wayo RTI International bapimishije icyo bakora mu cyo bise ibidukikije 7575 - ubuhehere bwo mu nzu n’ubushyuhe bikomeza kuri 75 ° C. Iki kizamini kirimo ibyiciro bibiri byo gupima abashoferi, bititaye ku umuyoboro. Igishushanyo mbonera cya stade imwe igura make, ariko ibuze umuzenguruko wihariye ubanza guhindura AC kuri DC hanyuma ukagenga ikigezweho, kikaba cyihariye kubishushanyo mbonera.

Minisiteri ishinzwe ingufu muri Leta zunze ubumwe z’Amerika yatangaje ko mu kizamini cya drives 11 zitandukanye, izo drives zose zakoze amasaha 1000 mu bidukikije 7575. Iyo ikinyabiziga giherereye mucyumba cy’ibidukikije, umutwaro wa LED uhujwe na disiki uba uri munsi y’ibidukikije byo hanze, bityo ibidukikije bya AST bigira ingaruka kuri disiki gusa. DOE ntabwo yahujije igihe cyo gukora mubihe bya AST nigihe cyo gukora mubidukikije bisanzwe. Icyiciro cya mbere cyibikoresho cyatsinzwe nyuma yamasaha 1250 yo gukora, nubwo ibikoresho bimwe na bimwe bikiri gukora. Nyuma yo kugerageza amasaha 4800, 64% yibikoresho byarananiranye. Nubwo bimeze bityo, urebye ibidukikije bigoye byo kugerageza, ibisubizo bimaze kuba byiza cyane.

Abashakashatsi basanze amakosa menshi abaho mugice cya mbere cyumushoferi, cyane cyane mugukosora ibintu (PFC) no kwivanga kwa electronique (EMI). Mubyiciro byombi byumushoferi, MOSFET nayo ifite amakosa. Usibye kwerekana uduce nka PFC na MOSFET zishobora kunoza igishushanyo mbonera, iyi AST irerekana kandi ko amakosa ashobora guhanurwa hashingiwe ku gukurikirana imikorere yumushoferi. Kurugero, kugenzura ibintu byingufu hamwe nibishobora kugaragara birashobora kumenya amakosa hakiri kare. Ubwiyongere bwa flashing burerekana kandi ko imikorere idahwitse.

Kuva kera, gahunda ya SSL ya DOE yagiye ikora ibizamini nubushakashatsi byingenzi murwego rwa SSL, harimo kugerageza ibicuruzwa byerekana ibicuruzwa munsi yumushinga wa Gateway hamwe no gupima ibicuruzwa byubucuruzi munsi yumushinga wa Caliper.
