Minisiteri ishinzwe ingufu muri Amerika (DOE) iherutse gushyira ahagaragara raporo yayo ya gatatu yo kwizerwa ku bashoferi ba LED ishingiye ku kwipimisha igihe kirekire. Abashakashatsi bo muri Minisiteri y’ingufu muri Leta zunze ubumwe z’Amerika zifite ingufu zikomeye (SSL) bemeza ko ibisubizo biheruka byemeza imikorere myiza y’uburyo bwihuse bw’ikigereranyo (AST) 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, nkaLED ibice ubwabyo, ni ngombwa kubwiza bwumucyo mwiza. Igishushanyo mbonera gikwiye gishobora gukuraho flicker no gutanga itara rimwe. Kandi umushoferi nabwo birashoboka cyane muriAmatara ya LEDcyangwa kumurika ibikoresho kugirango bidakora neza. 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 y’ingufu muri Amerika yabanje gusohora raporo ebyiri zerekeye inzira yo kwipimisha n’iterambere, none ni raporo ya gatatu y’ibizamini, ikubiyemo ibisubizo by’ibicuruzwa byakozwe mu bihe bya AST mu masaha 6000 kugeza 7500.

Mubyukuri, inganda ntizifite umwanya munini wo kugerageza drives ahantu hasanzwe ikora mumyaka myinshi. Ibinyuranye na byo, Minisiteri y’ingufu muri Amerika n’umushinga wayo RTI International bagerageje iyo disiki mu cyo bise ibidukikije 7575 - haba mu butumburuke bw’imbere ndetse n’ubushyuhe bikomeza kubikwa kuri 75 ° C. Iki kizamini kirimo ibyiciro bibiri byo kwipimisha 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 Amerika yatangaje ko mu bizamini byakorewe kuri drives 11 zitandukanye, drives zose zakorewe mu bidukikije 7575 mu gihe cy’amasaha 1000. 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 ikora ibizamini nubushakashatsi byingenzi mubice bya SSL, harimo no kuri Gateway
