Ibara ryerekana amabara (CRI) ya LED imirongo
2024-09-13 14:33:34
Ibara ryerekana amabara (CRI) nikintu gikunze gukoreshwa mubijyanye nubuhanga bwo gucana. Yerekeza ku gipimo cy'urwego ibara ry'ikintu rihoraho iyo rimurikirwa n'iri soko ry'umucyo n'igihe rimurikirwa n'umucyo usanzwe (muri rusange ukoresha urumuri rw'izuba nk'isoko risanzwe ry'umucyo), ni ukuvuga, uburyo ibara ni.
1.CRI ibisobanuro
Kubimenyereza kumurika, indangagaciro yo gutanga amabara (CRI) ni ijambo risanzwe rikoreshwa. Dukunze kubona agaciro ka CRI mumibare yinkomoko yumucyo, kandi tuzi ko yerekana ubwiza bwisoko yumucyo mubijyanye no gutanga amabara.
Ariko mubyukuri bivuze iki? Agaciro CRI ifasha kumenya inkomoko yumucyo igomba gukoreshwa mugikoresho kimurika. Hejuru ya CRI agaciro, nibyiza, ariko abantu bazi icyo bipima muburyo bwo kubipima? Kurugero, CRI agaciro ka OLIGHT S1MINI ni 90. Ni ayahe makuru atanga? Ubwiza bwo kumurika inzu ndangamurage bugomba kuba hejuru ya CRI 95. Kubera iki?
Kubivuga mu buryo bworoshe: gutanga amabara ni ikintu cyingenzi mugusuzuma ubuziranenge bwurumuri, naho indangagaciro yo gutanga amabara nuburyo bwingenzi bwo gusuzuma ibara ryerekana amasoko yumucyo. Nibintu byingenzi byo gupima ibara riranga inkomoko yumucyo. Kurwego rwo hejuru rwerekana amabara, niko amabara atanga isoko yumucyo. Ibara ryiza, nubushobozi bwo kugarura ibara ryikintu.
Komisiyo mpuzamahanga ishinzwe kumurika (CIE) isobanura gutanga amabara nk: ingaruka zumucyo kumabara kumabara yibintu ugereranije nibisanzwe bitanga urumuri.
Muyandi magambo, CRI nuburyo bwo gupima ibara ryerekana ibara ryumucyo ugereranije numucyo usanzwe (nkumucyo). CRI ni metero yemewe na bose kandi niyo nzira yonyine yo gusuzuma no gutanga raporo yerekana ibara ryerekana isoko yumucyo. inzira.
Ishyirwaho ryibipimo bya CRI ntabwo riri kure. Intego yambere yo gushyiraho iki gipimo kwari ukuyikoresha kugirango isobanure ibara ryerekana amabara yamatara ya fluorescent yakoreshejwe cyane mumwaka wa 1960, no gufasha abayikoresha kumva ko amatara ya fluorescent hamwe nogukwirakwiza umurongo bishobora gukoreshwa mubihe bihe.
Ikoranabuhanga rya CRI
Nubwo ibara ryibara ryerekanwe neza kandi ibintu bifatika bishobora kubyara amabara yibi bisobanuro, ni ngombwa kumva ko indangagaciro za CRI zikomoka muburyo bwo kubara kandi ntabwo byanze bikunze zimurikira ibara ryukuri rifite isoko nyayo.
Icyo tugomba gukora ni ugukoresha urumuri rwapimwe urumuri rwapimwe kugirango tugereranye nurutonde rwibara ryerekana urugero, hanyuma dukure kandi tubare agaciro CRI dukoresheje isesengura ryimibare.
Kubwibyo, gupima agaciro ka CRI ni byinshi kandi bifite intego. Ntabwo aribwo buryo bwo gupima ibintu bifatika (gupima ibintu bishingiye gusa ku ndorerezi yatojwe kugirango hamenyekane isoko yumucyo ifite amabara meza).
Kugereranya gushingiye kumyumvire yamabara nabyo birasobanutse, mugihe ubushyuhe bwamabara bwumucyo wapimwe hamwe nisoko yumucyo bigomba kuba bimwe.
Kurugero, kugerageza kugereranya isura yibibiri bibiri bisa bisa bimurikirwa nisoko yumucyo wera ushyushye hamwe nubushyuhe bwamabara ya 2900K hamwe nisoko ryera ryera ryera (kumanywa) hamwe nubushyuhe bwamabara ya 5600K ni uguta igihe.
Bagomba kugaragara bitandukanye, bityo ubushyuhe bwibara rifitanye isano (CCT) yumucyo wapimwe ubarwa uhereye kumurongo wumucyo. Umaze kugira ubu bushyuhe bwibara, irindi soko ryumucyo wubushyuhe bumwe burashobora gushirwaho mubiharuro.
Ku isoko yumucyo wapimwe hamwe nubushyuhe bwamabara buri munsi ya 5000K, isoko yumucyo ni radiyo yumukara (Planck), naho kumucyo wapimwe ufite ubushyuhe bwamabara burenze 5000K, isoko yumucyo ni CIE isanzwe imurika D.
Ihitamo rishobora guhuza urwego rwumucyo utanga isoko hamwe na buri bara ryicyitegererezo kugirango habeho urutonde rwibintu byiza byerekana ibara rihuza ingingo (ibara ryibara rigufi).
Kimwe nukuri kumasoko yumucyo uri kugeragezwa. Ikirangantego cyumucyo utanga ikizamini gihujwe na buri bara icyitegererezo kugirango ubone urundi rutonde rwamabara. Niba ibara ryibara munsi yumucyo wapimwe rihuye neza neza nibara ryamabara munsi yumucyo utanga urumuri, tubona ko ibara ryabo ryerekana amabara amwe kandi tugashyiraho CRI agaciro kayo 100.
Mu mbonerahamwe yamabara, kure cyane ibara ryibara munsi yumucyo wapimwe ni isoko ijyanye nibyiza, ibara ryerekana nabi kandi nigiciro cya CRI.
Kubara ibara ryimurwa ryibice 8 byamabara atandukanye, hanyuma ubare indangagaciro 8 zidasanzwe zerekana amabara (CRI agaciro k'umucyo uturuka kumurongo runaka w'icyitegererezo cyitwa amabara yihariye yerekana indangagaciro), hanyuma ufate ibisobanuro byabo byerekana imibare, bityo agaciro kabonetse ni CRI agaciro.
CRI agaciro ka 100 bivuze ko nta tandukanyirizo ryamabara riri hagati yikibiri cyamabara yibice umunani yibara ryerekana amabara munsi yumucyo wapimwe nisoko yumucyo.
3.Ni ubuhe buryo bwo kwerekana amabara yerekana amatara ya LED biterwa?
Ibara ryerekana amabara yerekana amatara ya LED ahanini biterwa nubwiza nigipimo cya fosifore. Ubwiza nigipimo cya fosifore bigira ingaruka zikomeye kumurongo wamabara yerekana amatara ya LED. Fosifike yo mu rwego rwo hejuru irashobora gutanga ubushyuhe bwiza bwamabara hamwe nubushyuhe buto bwamabara, bityo bikazamura ibara ryerekana amabara. 12
Ibinyabiziga bigenda nabyo bizagira ingaruka kumabara yerekana urumuri rwa LED. Ikinini kinini cyo gutwara kizatera ubushyuhe bwamabara kugendagenda hejuru yubushyuhe bwo hejuru bwamabara, bityo bigabanye ibara ryerekana amabara.
Sisitemu yo gukwirakwiza ubushyuhe bwa LED nayo igira ingaruka runaka kumurongo wo gutanga amabara. Sisitemu yizewe yo gukwirakwiza ubushyuhe irashobora kwemeza imikorere yumucyo wa LED kandi ikagabanya urumuri rwerekana ibara ryerekana ibara ryatewe no kuzamuka kwubushyuhe.
Gukwirakwiza gukwirakwiza urumuri ni ikintu cyingenzi mu kumenya ibara ryerekana amabara. Ingano nuburemere bwamabara atandukanye akubiye murwego rugira ingaruka itaziguye. Mugari mugukwirakwiza gukwirakwiza, hejuru yerekana ibara ryerekana amabara, hamwe nuburyo bwiza bwo gukora ibara.
