Ibara ritanga indangagaciro (CRI) kandi ni ukubera iki ari ngombwa kuyobora itara?
Ntushobora kuvuga itandukaniro riri hagati yisogisi yumukara na Navy-Navy mukigo cyawe munsi yamatara yawe ya kera ya fluorescent? Birashoboka ko isoko yo kumurika ifite urwego ruto cyane rwa CRI. Ibara ryahinduwe (CRI) ni igipimo cyukuntu amabara asanzwe ahinduka munsi yinkomoko yera yera mugihe ugereranije nizuba. Ironderero ripimwa kuva 0-100, hamwe nuduhazwe 100 herekana ko amabara yibintu munsi yinkomoko yoroheje bigaragara ko yaburirwa izuba. Cris munsi yimyaka 80 muri rusange ifatwa nk 'abakene' mugihe iringaniye hejuru ya 90 zifatwa nk 'ikomeye'.
CRI CRI, Cri yatumye hanone amabuye meza, afite imbaraga zo hejuru yamabara yuzuye. Ariko, CRI ni igipimo kimwe gusa kumiterere yoroheje. Kugira ngo wumve neza ubushobozi bwumucyo bwo gutanga amabara ushaka, hari ibigeragezo byimbitse dukora hamwe nabahanga mu bya siyansi birasaba. Tuzasobanura neza hano.
Niki CRI iyobora gukoresha
Mugihe ugura kandi ushyiraho amatara yayobowe yera, turasaba cri ya 90 ariko tukavuga mumishinga imwe n'imwe, byibuze 85 birashobora kwemerwa. Hasi ni ibisobanuro bigufi bya CRI,
CRI 95 - 100 → Ibara ryiza. Amabara agaragara nkuko bikwiye, amajwi yoroshye arasohoka kandi amenyerewe, uruhu rwuruhu rusa neza, ubuhanzi buba muzima, inyuma na barangi berekana amabara yabo nyayo.
Byakoreshejwe cyane mumusaruro wa Hollywood, amaduka yinyuma, icapa no gusiga irangi, gushushanya amahoteri, ibikoresho byubukorikori, no gukodesha aho amabara asanzwe akeneye kumurika.
CRI 90 - 95 → Ibara rikomeye! Amabara hafi ya yose 'pop' kandi aratandukanye byoroshye. Biragaragara ko itara rikomeye ritangira kuri 90. Amabara yawe aherutse kwishyiriraho amabara mugikoni cyawe azasa neza, afite imbaraga, kandi arazura byuzuye. Abashyitsi batangira kwishima, irangi, nibisobanuro byigikoni cyawe, ariko bike birabamenyera ahanini babitangaje.
CRI 80 - 90 →Ibara ryiza, aho amabara menshi ahindurwa neza. Byemewe kubikoresho byinshi. Ntushobora kubona ibintu byuzuye nkuko ubishaka.
CRI hepfo 80 →Kumurika hamwe na CRI hepfo 80 byaba bifatwa nkibifite ibara ribi. Munsi yuru rumuri, ibintu namabara birashobora kugaragara byihuta, drab, rimwe na rimwe bidashoboka (nko kutabasha kubona itandukaniro riri hagati yisoni yumukara na marvy). Byaba bigoye gutandukanya amabara asa.
Ibara ryiza ni urufunguzo rwo gufotora, gucuruza ububiko bwerekana, amatara yububiko, ibishushanyo, nububiko kugirango bita kumwe bake. Hano, isoko yumucyo hamwe na Cri yavuzwe haruguru 90 izemeza ko amabara asa neza nuburyo bagomba, bahindukira neza kandi bakagaragara neza. Kumurika hejuru ya CRI bifite agaciro kabisanzwe, nkuko bishobora guhindura icyumba mubishushanyo mbonera no gukora ibintu byiza, bisanzwe. Irangiye izaba ifite ubujyakuzimu no kurahira.
Kwipimisha Cri
Kwipimisha Cri bisaba imashini zidasanzwe zagenewe byumwihariko kubwiyi ntego. Muri iki kizamini, urumuri rwitara rwasesenguwe mumabara umunani atandukanye (cyangwa "r indangagaciro"), yitwa R1 binyuze kuri R8.
Hano hari ibipimo 15 bishobora kugaragara hepfo, ariko igipimo cya CRI gikoresha gusa 8-100 kuri buri bara ritagereranywa ugereranije nisoko yumucyo nkizuba. Urashobora kubona kurugero hepfo, nubwo ishusho ya kabiri ifite cri ya 81, biteye ubwoba muguhindura ibara ry'umutuku (R9).
Ubu bworozi Urutonde Ubu urutonde rwa CRI, kandi ibikorwa bya leta nka Californiya Umutwe wa Californiya 24 Menya neza ko Itara rinoze, Hejuru Cri
Nubwo uzirikana ko CRI atari uburyo bwonyine bwo gupima imirabyo; Raporo yubushakashatsi bwo gucana kandi irasaba ko ikoreshwa rya TM-30-20 Gamut Agace ka Gamut.
CRI yakoreshejwe nkigipimo kuva 1937. Bamwe bemeza ko igipimo cya CRI gifite inenge kandi kikagera, kuko hari inzira nziza zo gupima ireme ryo gutanga isoko. Ibi bipimo byinyongera ni ibara ryiza (cqs), ies TM-30-20 harimo no kwerekana imikino, icyerekezo cyiza, ibara.
CRI - Ibara ryerekana indangagaciro -Mbega ukuntu urumuri rwagaragaye rushobora gutanga amabara nk'izuba, dukoresheje ibara 8.
Ironderero ryiza (TM-30) -Mbega ukuntu urumuri rwagaragaye rushobora gutanga amabara nk'izuba, dukoresheje ibara 99.
Urupapuro rwa Gamut (TM-30) - Nigute amabara yuzuye cyangwa yashutswe ari (Aka ukomera cyane).
Ibara rya vector (TM-30) - Ni ayahe mabara yuzuye / yashimishijwe kandi niba hari ihinduka rya hue muri kimwe mu binini 16.
CQS -Igipimo cyiza cyurugero - ubundi buryo bwo gupima CRI. Hano hari amabara 15 yuzuye akoreshwa mukugereranya ivangura chromatic, ukunda, namabara.
Ninde wayoboye urumuri rwinshi kumushinga wawe?
Twateguye imirongo yose yacu yera yera kugirango tugire CRIO hejuru ya 90 hamwe nimwe gusa nimwe gusa (kubikoresha inganda), bivuze ko bakora akazi keza gahindura amabara nibintu bimurikira.
Ku mpera yibintu, twashizeho kimwe muri Cri ya CRI LED yayoboye abafite ibipimo byihariye cyangwa kumafoto, televiziyo. Ultrabright ™ Urukurikirane rufite hafi-indangagaciro zitunganye, harimo amanota menshi ya R9. Urashobora kubona hano raporo zose za Photometric aho ushobora kubona indangagaciro za CRI kubice byacu byose.
Amatara yacu ya LED yayoboye hamwe nutubari byumucyo biza muburyo bwinshi bwumucyo, ubushyuhe bwamabara, nuburebure. Ibyo bahurizaho ni hejuru cyane CRI (na Cqs, Tlci, TM-30-20). Muri buri rupapuro rwibicuruzwa, uzasangamo raporo za Photometric zerekana ibyo bisomye.
Kugereranya na Cri Nyiri ya LED yayoboye
Hasi uzabona kugereranya hagati yumucyo (lumens kumaguru) ya buri gicuruzwa. Buri gihe turaboneka kugirango tugufashe guhitamo ibicuruzwa byiza.
