Iyini I-Colour Rendering Index (CRI) futhi Kungani Ibalulekile Ekukhanyeni Kwe-LED?
Awukwazi ukubona umehluko phakathi kwamasokisi anombala omnyama nasolwandle ekhabetheni lakho lokungena ngaphansi kwamalambu akho amadala e-fluorescent? Kungenzeka ukuthi umthombo wokukhanyisa wamanje unezinga eliphansi kakhulu le-CRI. I-Colour Rendering Index (CRI) isilinganiso sendlela imibala yemvelo esebenza ngayo ngaphansi komthombo wokukhanya wokwenziwa omhlophe uma iqhathaniswa nokukhanya kwelanga. Inkomba ikalwa ukusuka ku-0-100, ngo-100 ophelele obonisa ukuthi imibala yezinto ezingaphansi komthombo wokukhanya ibonakala ifana naleyo ebingenzeka ngaphansi kokukhanya kwelanga okungokwemvelo. Ama-CRI angaphansi kwama-80 ngokuvamile abhekwa 'njengampofu' kuyilapho ububanzi obungaphezu kuka-90 bubhekwa 'njengemikhulu'.
Ukukhanya okuphezulu kwe-CRI LED kunikeza amathoni amahle, agqamile kuwo wonke umbala ogcwele. Nokho, i-CRI iyisilinganiso esisodwa kuphela sekhwalithi yokukhanya. Ukuze uqonde ngempela amandla omthombo wokukhanya wokunikeza imibala oyifunayo, kukhona ukuhlola okujulile esikwenzayo futhi ososayensi bethu bokukhanyisa bayatusa. Sizokuchaza kabanzi lokho lapha.
Iyiphi I-CRI Ranges okufanele isetshenziswe
Uma uthenga futhi ufaka izibani ze-LED ezimhlophe, sincoma i-CRI engaphezu kuka-90 kodwa futhi sithi kwamanye amaphrojekthi, ubuncane obungu-85 bungamukeleka. Ngezansi kunencazelo emfushane yamabanga e-CRI:
I-CRI 95 - 100 → Ukunikezwa kombala okumangalisayo. Imibala ibonakala njengoba kufanele, amathoni acashile aphuma futhi agcizelelwe, amathoni esikhumba abukeka emuhle, ubuciko buyaphila, ama-backsplashes nopende kubonisa imibala yabo yangempela.
Isetshenziswa kabanzi kumasethi okukhiqiza e-Hollywood, izitolo zezitolo ezisezingeni eliphezulu, izitolo zokuphrinta nezokupenda, amahhotela edizayini, amagalari obuciko, nasezinhlelweni zokuhlala lapho imibala yemvelo idinga ukukhanya ngokugqamile.
I-CRI 90 - 95 → Ukunikezwa kombala okuhle! Cishe yonke imibala 'ye-pop' futhi ibonakala kalula. Ukukhanya okuhle ngokuphawulekayo kuqala ku-CRI engu-90. I-backsplash yakho esanda kufakwa enombala ophuzi ekhishini lakho izobukeka iyinhle, igqamile, futhi igcwele ngokugcwele. Izivakashi ziqala ukuncoma izinto zokubala, upende, kanye nemininingwane yekhishi lakho, kodwa kuncane kakhulu ukuthi ukukhanya kuyimbangela yokuthi libukeke limangalisa kakhulu.
I-CRI 80 - 90 →Ukunikezwa kombala okuhle, lapho imibala eminingi inikezwa kahle. Kwamukelekile ekusetshenzisweni okuningi kwezentengiso. Ungase ungaboni izinto zigcwele ngokugcwele ngendlela obungathanda ngayo.
I-CRI Ngaphansi kuka-80 →Ukukhanyisa nge-CRI engaphansi kuka-80 kuzobhekwa njengokunikeza umbala ompofu. Ngaphansi kwalokhu kukhanya, izinto nemibala ingase ibukeke ingenalutho, idonsa kanzima, futhi ngezinye izikhathi ingabonakali (njengokungakwazi ukubona umehluko phakathi kwamasokisi amnyama nawombala we-navy). Kungaba nzima ukuhlukanisa phakathi kwemibala efanayo.
Ukunikezwa kombala okuhle kuwukhiye wokuthwebula izithombe, izibonisi zezitolo zezitolo, ukukhanya kwesitolo segrosa, imibukiso yobuciko, namagalari ukusho nje ezimbalwa. Lapha, umthombo wokukhanya one-CRI engaphezu kuka-90 uzoqinisekisa ukuthi imibala kufanele ibukeke ngendlela efanele, inikezwe ngokunembile futhi ibonakale icwebezela futhi ikhanya kakhudlwana. Ukukhanyisa okuphezulu kwe-CRI kubaluleke ngokufanayo ezinhlelweni zokuhlala, njengoba kungashintsha igumbi ngokugqamisa imininingwane yokuklama nokudala ukunethezeka, umuzwa wemvelo jikelele. Ukuqeda kuzoba nokujula nokucwebezela okwengeziwe.
Ukuhlola i-CRI
Ukuhlolwa kwe-CRI kudinga imishini ekhethekile eklanyelwe le njongo ngqo. Phakathi nalokhu kuhlolwa, i-spectrum yokukhanya yesibani ihlaziywa ibe imibala eyisishiyagalombili ehlukene (noma “amanani ka-R”), ebizwa ngokuthi R1 kuya ku-R8.
Kunezilinganiso ezingu-15 ezingabonakala ngezansi, kodwa isilinganiso se-CRI sisebenzisa esokuqala esingu-8 kuphela. Isibani sithola amaphuzu ukusuka ku-0-100 kumbala ngamunye, ngokusekelwe endleleni umbala owenziwe ngayo wemvelo uma kuqhathaniswa nendlela umbala obukeka ngayo ngaphansi Umthombo wokukhanya “ophelele” noma “oyisithenjwa” njengokukhanya kwelanga ezingeni lokushisa elifanayo lombala. Ungabona ezibonelweni ezingezansi, nakuba isithombe sesibili sine-CRI engu-81, kubi ukunikeza umbala obomvu (R9).
Abakhiqizi bezibani manje baklelisa izilinganiso ze-CRI emikhiqizweni yabo, futhi imizamo kahulumeni efana ne-California Title 24 iqinisekisa ukufakwa kwezibani ezisebenza kahle, eziphezulu ze-CRI.
Nakuba khumbula ukuthi i-CRI akuyona indlela yokuma yodwa yokulinganisa ikhwalithi yokukhanyisa; umbiko we-Lighting Research Institute uphinde uncome ukusetshenziswa okuhlangene kwe-TM-30-20 Gamut Area Index.
I-CRI isetshenziswe njengesilinganiso kusukela ngo-1937. Abanye bakholelwa ukuthi ukulinganisa kwe-CRI kunephutha futhi kuphelelwe yisikhathi, njengoba kunezindlela ezingcono manje zokulinganisa ikhwalithi yokunikezwa okuvela emthonjeni wokukhanya. Lezi zilinganiso ezengeziwe I-Color Quality Scale (CQS), IES TM-30-20 kuhlanganise ne-Gamut Index, Fidelity Index, Vector Yombala.
I-CRI - Inkomba Yokunikeza Umbala -Ukukhanya okubhekiwe kungayinikeza ngokuseduze kangakanani imibala efana nelanga, kusetshenziswa amasampula emibala ayi-8.
I-Fidelity Index (TM-30) -Ukuthi ukukhanya okubhekiwe kungayiveza ngokuseduze kangakanani imibala efana nelanga, kusetshenziswa amasampula ombala angu-99.
I-Gamut Index (TM-30) – Yeka ukuthi imibala egcwele noma egcwele kangakanani (okuwukuthi imibala ishube kangakanani).
I-vector yombala Graphic (TM-30) – Yimiphi imibala egcwele/ecishiwe nokuthi ingabe kukhona ukushintsha kombala kunoma yimiphi imigqomo yemibala engu-16.
CQS -Isikali Sekhwalithi Yombala - Enye yemibala yokulinganisa ye-CRI engagcwalisiwe. Kukhona imibala engu-15 egcwele kakhulu esetshenziselwa ukuqhathanisa ukubandlululwa kwe-chromatic, okuthandwa ngabantu, nokunikezwa kombala.
Ikuphi Ukukhanya Kwe-LED Strip Okungcono Kakhulu Kuphrojekthi Yakho?
Siklame yonke imichilo yethu ye-LED emhlophe ukuthi ibe ne-CRI ephezulu engaphezu kuka-90 ngaphandle kokukhetha okukodwa kuphela (okusetshenziselwa imboni), okusho ukuthi yenza umsebenzi omuhle kakhulu wokunikeza imibala yezinto nezikhala ozikhanyisayo.
Phezulu kwezinto, senze enye yezibani eziphakeme kakhulu ze-CRI LED zalabo abanamazinga akhethekile noma izithombe, ithelevishini, umsebenzi wendwangu. I-UltraBright™ Render Series inamanani acishe aphelele e-R, afaka amaphuzu aphezulu angu-R9. Ungathola lapha yonke imibiko yethu ye-photometric lapho ungabona khona amanani e-CRI ayo yonke imicu yethu.
Izibani zethu ze-strip ye-LED namabha akhanyayo ziza ngezinhlobonhlobo eziningi zokukhanya, amazinga okushisa emibala, nobude. Abafana ngakho i-CRI ephezulu kakhulu (kanye ne-CQS, TLCI, TM-30-20). Ekhasini ngalinye lomkhiqizo, uzothola imibiko ye-photometric ebonisa konke lokhu kufundwa.
Ukuqhathaniswa kwe-High CRI LED Strip Lights
Ngezansi uzobona ukuqhathanisa phakathi kokukhanya (lumens ngonyawo ngalunye) komkhiqizo ngamunye. Sihlala sitholakala ukuze sikusize ekukhetheni umkhiqizo olungile futhi.
