Indangantego yo gutanga amabara ni iki (CRI) kandi ni ukubera iki ari ngombwa kumurika LED?
Ntushobora kuvuga itandukaniro riri hagati yamasogisi yumukara na navy-amabara mu kabati kawe munsi yumucyo wawe wa fluorescent? Birashoboka ko isoko yumucyo ifite urwego rwo hasi cyane CRI. Ibara ryerekana amabara (CRI) ni igipimo cyerekana uburyo amabara karemano atanga munsi yumucyo wera wera ugereranije nizuba. Ironderero ripimwa kuva 0-100, hamwe 100 byuzuye byerekana ko amabara yibintu munsi yumucyo bigaragara nkaho byari munsi yizuba risanzwe. CRIs munsi yimyaka 80 ifatwa nk 'abakene' mugihe intera irenga 90 ifatwa nk '' ikomeye '.
Amatara maremare ya CRI LED atanga amajwi meza, afite imbaraga hejuru yamabara yuzuye. Ariko, CRI ni igipimo kimwe gusa cyubwiza bwurumuri. Kugirango usobanukirwe neza nubushobozi bwumucyo ubushobozi bwo gutanga amabara ushaka, hariho ibizamini byimbitse dukora kandi abahanga bacu bamurika. Tuzabisobanura birambuye hano.
Nibihe CRI Ikoreshwa
Mugihe cyo kugura no gushiraho amatara yera ya LED, turasaba CRI irenga 90 ariko nanone tuvuge mumishinga imwe n'imwe, byibuze 85 irashobora kwemerwa. Hano haribisobanuro bigufi byerekana urwego CRI:
CRI 95 - 100 → Ibara ryerekana amabara. Amabara agaragara nkuko bikwiye, amajwi yoroheje arasohoka kandi arashimangirwa, imiterere yuruhu isa neza, ubuhanzi buza ari muzima, gusubira inyuma no gusiga irangi byerekana amabara yabo nyayo.
Ikoreshwa cyane mubikorwa bya Hollywood, ibicuruzwa byo mu rwego rwo hejuru byo kugurisha, amaduka yo gucapa no gusiga amarangi, amahoteri ashushanya, ububiko bwubukorikori, no mubisabwa gutura aho amabara asanzwe akeneye kumurika cyane.
CRI 90 - 95 → Guhindura amabara meza! Amabara hafi ya yose 'pop' kandi arashobora gutandukana byoroshye. Ikigaragara ni uko itara ryinshi ritangirira kuri CRI ya 90.Icyapa cyawe gishya cyashizwemo amabara yicyayi mugikoni cyawe kizaba cyiza, gifite imbaraga, kandi cyuzuye. Abashyitsi batangira gushima compte, gusiga irangi, nibisobanuro byigikoni cyawe, ariko bike ntibamurika ahanini bashinzwe kubireba bitangaje.
CRI 80 - 90 →Gutanga amabara meza, aho amabara menshi yatanzwe neza. Biremewe kubikoresha byinshi mubucuruzi. Ntushobora kubona ibintu byuzuye nkuko ubishaka.
CRI Munsi ya 80 →Kumurika hamwe na CRI munsi ya 80 byafatwa nkibara ryerekana nabi. Munsi yurumuri, ibintu namabara birashobora kugaragara nkibicucu, drab, kandi rimwe na rimwe bitamenyekana (nko kutabasha kubona itandukaniro riri hagati yamasogisi yumukara na navy). Byaba bigoye gutandukanya amabara asa.
Guhindura amabara meza ni urufunguzo rwo gufotora, kwerekana ibicuruzwa byerekanwe, kumurika ububiko bwibiryo, kwerekana ibihangano, hamwe na galeries kugirango tuvuge bike. Hano, isoko yumucyo hamwe na CRI hejuru ya 90 izemeza ko amabara asa neza uko agomba, yatanzwe neza kandi agaragara neza kandi neza. Amatara maremare ya CRI afite agaciro kamwe mubisabwa gutura, kuko bishobora guhindura icyumba mugaragaza ibisobanuro birambuye no gukora ibintu byiza, bisanzwe muri rusange. Kurangiza bizagira ubujyakuzimu kandi burabagirana.
Kwipimisha CRI
Kwipimisha kuri CRI bisaba imashini zidasanzwe zabugenewe kubwiyi ntego. Muri iki kizamini, urumuri rwamatara rusesengurwa mumabara umunani atandukanye (cyangwa “R agaciro”), bita R1 kugeza kuri R8.
Hano hari ibipimo 15 bishobora kugaragara hepfo, ariko gupima CRI ikoresha gusa 8. Icya mbere. Itara ryakira amanota kuva 0-100 kuri buri bara, ukurikije uburyo ibara risanzwe ritangwa ugereranije nuburyo ibara risa munsi ya a Inkomoko yumucyo "itunganye" cyangwa "reference" nkumucyo wizuba mubushyuhe bumwe. Urashobora kubona kurugero rukurikira, nubwo ishusho ya kabiri ifite CRI ya 81, biteye ubwoba muguhindura ibara ritukura (R9).
Abakora amatara ubu berekana urutonde rwa CRI kubicuruzwa byabo, kandi gahunda za leta nka Californiya Umutwe wa 24 zituma hashyirwaho amatara meza ya CRI.
Nubwo uzirikane ko CRI atariyo nzira yonyine yo gupima ubuziranenge bwamatara; Raporo y'Ikigo gishinzwe Ubushakashatsi kandi irasaba ko hakoreshwa icyerekezo cya TM-30-20.
CRI yakoreshejwe nk'igipimo kuva mu 1937. Bamwe bemeza ko gupima CRI ari inenge kandi itajyanye n'igihe, kubera ko hari uburyo bwiza bwo gupima ubuziranenge bwo gutanga buturuka ku mucyo. Ibipimo byinyongera ni Ibipimo Byiza Byibara (CQS), IES TM-30-20 harimo Indangantego ya Gamut, Indangagaciro Yizerwa, Ibara rya Vector.
CRI - Ironderero ryerekana amabara -Ukuntu urumuri rwagaragaye rushobora guhindura amabara nkizuba, ukoresheje ingero 8 zamabara.
Ironderero ry'ubudahemuka (TM-30) -Ukuntu urumuri rwagaragaye rushobora guhindura amabara nkizuba, ukoresheje amabara 99.
Ironderero rya Gamut (TM-30) - Ukuntu amabara yuzuye cyangwa yataye agaciro (aka nukuntu amabara akomeye).
Ibara ryerekana ibara (TM-30) - Ni ayahe mabara yuzura / yataye agaciro kandi niba hari ihinduka rya hue muri kimwe muri bino 16 y'amabara.
CQS -Ibara ryiza Ibipimo - Ubundi buryo bwo gupima ibara rya CRI ridahagije. Hano hari amabara 15 yuzuye cyane akoreshwa mukugereranya ivangura rya chromatic, ibyo abantu bakunda, hamwe no gutanga amabara.
Nuwuhe LED Strip Itara ryiza kumushinga wawe?
Twashizeho imirongo yacu yera ya LED kugirango tugire CRI ndende hejuru ya 90 usibye imwe gusa (yo gukoresha inganda), bivuze ko bakora akazi keza ko gutanga amabara yibintu n'umwanya urimo kumurika.
Ku mpera yibintu, twashizeho rimwe mumatara maremare ya CRI LED kumurongo kubafite ibipimo byihariye cyangwa kumafoto, tereviziyo, imirimo yimyenda. UltraBright ™ Gutanga Urukurikirane rufite hafi-yuzuye R indangagaciro, harimo amanota R9 yo hejuru. Urashobora gusanga hano raporo zacu zose zifotora aho ushobora kubona indangagaciro za CRI kumurongo wose.
Amatara yacu ya LED n'amatara yumucyo biza muburyo bwinshi bwurumuri, ubushyuhe bwamabara, nuburebure. Icyo bahurizaho ni CRI ndende cyane (na CQS, TLCI, TM-30-20). Muri buri rupapuro rwibicuruzwa, uzasangamo raporo yerekana amafoto yerekana ibyo wasomye byose.
Kugereranya Amatara maremare ya CRI LED
Hasi urahabona kugereranya hagati yumucyo (lumens kumaguru) ya buri gicuruzwa. Buri gihe turaboneka kugirango tugufashe guhitamo ibicuruzwa byiza nabyo.
