Yintoni i-Colour Rendering Index (i-CRI) kwaye kutheni ibalulekile ekukhanyeni kwe-LED?
Ngaba awukwazi ukuchazela umahluko phakathi kweekawusi ezimnyama kunye ne-navy-colored kwi-closet yakho yokuhamba phantsi kwezibane zakho zakudala ze-fluorescent? Kungenzeka ukuba umthombo wokukhanyisa wangoku unezinga eliphantsi kakhulu le-CRI. Isalathiso sokuBonelelwa koMbala (CRI) ngumlinganiselo wendlela imibala yendalo esebenza ngayo phantsi komthombo wokukhanya owenziweyo omhlophe xa uthelekiswa nokukhanya kwelanga. Isalathiso silinganiswa ukusuka ku-0 ukuya kwi-100, kunye ne-100 egqibeleleyo ebonisa ukuba imibala yezinto eziphantsi komthombo wokukhanya ibonakala ifana njengoko bekuya kuba njalo phantsi kokukhanya kwelanga. Ii-CRIs ezingaphantsi kwama-80 zithathwa ngokuba 'zimbi' ngelixa uluhlu olungaphezulu kwama-90 lubonwa 'lulukhulu'.
Ukukhanya okuphezulu kwe-CRI ye-LED kunika iithowuni ezintle, eziphilileyo kuwo wonke umbala ogcweleyo. Nangona kunjalo, i-CRI ngumlinganiselo omnye kuphela womgangatho wokukhanya. Ukuqonda ngokwenene amandla omthombo wokukhanya ukunika imibala oyifunayo, kukho uvavanyo olunzulu esilwenzayo kwaye iinzululwazi zethu zokukhanyisa ziyacebisa. Siza kucacisa oko ngakumbi apha.
Yeyiphi iCRI enokuSebenziswa
Xa kuthengwa kwaye kufakwe izibane ezimhlophe ze-LED, sincoma i-CRI engaphezulu kwe-90 kodwa kwakhona ithi kwezinye iiprojekthi, ubuncinci be-85 bunokwamkeleka. Apha ngezantsi kukho ingcaciso emfutshane yoluhlu lweCRI:
CRI 95 - 100 → Unikezelo lombala omangalisayo. Imibala ibonakala njengoko ifanele, iithoni ezifihlakeleyo ziyaphuma kwaye zigxininiswe, iitoni zesikhumba zibukeka zihle, ubugcisa buyaphila, i-backsplashes kunye nepeyinti ibonisa imibala yabo yokwenyani.
Isetyenziswe ngokubanzi kwiiseti zemveliso yaseHollywood, iivenkile ezithengisayo eziphezulu, iivenkile zokuprinta kunye nepeyinti, iihotele zokuyila, iigalari zobugcisa, kunye nezicelo zokuhlala apho imibala yendalo kufuneka ikhanye ngokuqaqambileyo.
CRI 90 - 95 → Unikezelo oluhle lombala! Phantse yonke imibala 'pop' kwaye kulula ukuyiqonda. Okuqaphelekayo ukhanyiso olukhulu luqala kwi-CRI ye-90. I-backsplash yakho yombala weteal esanda kufakwa kwikhitshi lakho iya kujongeka intle, idlamkile, kwaye ihluthike ngokupheleleyo. Iindwendwe ziqala ukuncoma izinto zokubala, ipeyinti, kunye neenkcukacha zekhitshi lakho, kodwa kuncinci ukwenza ukukhanya kunoxanduva lokubonakala kumangalisa kakhulu.
CRI 80 - 90 →Unikezelo oluhle lombala, apho uninzi lwemibala lunikezelwa kakuhle. Yamkelekile kusetyenziso oluninzi lwezorhwebo. Usenokungaboni izinto zigcwele ngokupheleleyo njengoko ubungathanda.
CRI Ngaphantsi kwama-80 →Ukukhanyisa nge-CRI engaphantsi kwe-80 kuya kuthathwa njengonikezelo lombala olubi. Phantsi kolu kukhanya, izinto kunye nemibala inokujongeka iphelelwe, idonsa, kwaye ngamanye amaxesha ingabonakali (njengokungakwazi ukubona umahluko phakathi kweekawusi ezimnyama kunye ne-navy-colored). Kuya kuba nzima ukwahlula phakathi kwemibala efanayo.
Unikezelo olululo lombala ngundoqo wokufota, imiboniso yevenkile ethengisa ukutya, izibane zegrosari, imiboniso yobugcisa, kunye neegalari ukubala nje ezimbalwa. Apha, umthombo wokukhanya one-CRI engaphezulu kwe-90 uya kuqinisekisa ukuba imibala ijongeka ngqo ngendlela ekufanele ukuba yenziwe ngayo, inikezelwe ngokuchanekileyo kwaye ibonakale iqaqambile kwaye iqaqambile. Ukukhanya okuphezulu kwe-CRI kubaluleke ngokulinganayo kwizicelo zokuhlala, njengoko kunokuguqula igumbi ngokugqamisa iinkcukacha zoyilo kunye nokudala ukukhululeka, ukuvakalelwa kwendalo jikelele. Ukugqitywa kuya kuba nobunzulu kunye nokucwebezela.
Uvavanyo lwe-CRI
Ukuvavanyelwa i-CRI kufuna oomatshini abakhethekileyo abayilelwe le njongo. Ebudeni bolu vavanyo, ukukhanya kwesibane kuhlalutywa kube yimibala esibhozo eyahlukeneyo (okanye “amaxabiso e-R”), ebizwa ngokuba yi-R1 ukuya kwi-R8.
Kukho imilinganiselo ye-15 enokubonwa ngezantsi, kodwa umlinganiselo we-CRI usebenzisa kuphela i-8 yokuqala. "egqibeleleyo" okanye "ireferensi" umthombo wokukhanya njengokukhanya kwelanga kubushushu obufanayo bombala. Ungabona kwimizekelo engezantsi, nangona umfanekiso wesibini une-CRI ye-81, iyoyikeka ekunikezeni umbala obomvu (R9).
Abavelisi bezibane ngoku badwelisa iireyithingi ze-CRI kwiimveliso zabo, kunye namanyathelo karhulumente afana neSihlokwana sama-24 saseCalifornia siqinisekisa ukufakwa kokukhanya okusebenzayo, okuphezulu kwe-CRI.
Nangona ukhumbula ukuba i-CRI ayisiyiyo indlela yokuma yodwa yokulinganisa umgangatho wokukhanyisa; Ingxelo ye-Lighting Research Institute iphinda ikhuthaze ukusetyenziswa okudibeneyo kwe-TM-30-20 ye-Index yendawo ye-Gamut.
I-CRI isetyenziswe njengomlinganiselo ukususela ngo-1937. Abanye bakholelwa ukuba umlinganiselo we-CRI unesiphene kwaye uphelelwe yisikhathi, njengoko kukho iindlela ezingcono zokulinganisa umgangatho wokunikezela ukusuka kumthombo wokukhanya. Le milinganiselo eyongezelelweyo i-Colour Quality Scale (CQS), i-IES TM-30-20 kuquka i-Gamut Index, i-Fidelity Index, iVector yoMbala.
I-CRI-Isalathiso sokuBonelela ngoMbala-Ukukhanya okujongwe ngokukufutshane kunokunika imibala efana nelanga, kusetyenziswa iisampulu ezi-8 zemibala.
I-Fidelity Index (TM-30) -Ukusondele kangakanani ukukhanya okujongiweyo kunika imibala efana nelanga, kusetyenziswa iisampuli zemibala ezingama-99.
Isalathiso seGamut (TM-30) - Indlela ehluthe ngayo okanye ehlutheke kangakanani imibala (aka indlela ecace ngayo imibala).
Umzobo wevektha yombala (TM-30) – Yeyiphi imibala egcweleyo / ehluthiweyo kunye nokuba kukho utshintsho lwe-hue kuyo nayiphi na imigqomo ye-16 yemibala.
CQS -Isikali soMgangatho woMbala - Enye indlela kwimibala yokulinganisa i-CRI engaxutywanga. Kukho i-15 yemibala egcwele kakhulu esetyenziselwa ukuthelekisa ucalucalulo lwechromatic, ukhetho lomntu, kunye nokunikezelwa kombala.
Sesiphi isibane se-LED esiyeyona ilungileyo kwiProjekthi yakho?
Siyile zonke iintambo zethu ze-LED ezimhlophe ukuba zibe ne-CRI ephezulu ngaphezulu kwe-90 ngaphandle kokunye kuphela (ukusetyenziswa kwemizi-mveliso), okuthetha ukuba benza umsebenzi oncomekayo ngokunika imibala yezinto kunye neendawo ozikhanyisayo.
Kwisiphelo esiphezulu sezinto, senze esinye sezona zibane ziphakamileyo ze-CRI ze-strip ze-LED kwabo banemigangatho ethile okanye ukufota, umabonwakude, umsebenzi welaphu. I-UltraBright™ Render Series inamaxabiso akufutshane-agqibeleleyo e-R, kubandakanywa amanqaku aphezulu e-R9. Unokufumana apha zonke iingxelo zethu zefotometric apho unokubona amaxabiso e-CRI kuwo onke amacwecwe ethu.
Izibane zethu ze-LED kunye nemivalo yokukhanya ziza kwiindidi ezininzi zokuqaqamba, ubushushu bemibala, kunye nobude. Into abafana ngayo yi-CRI ephezulu kakhulu (kunye ne-CQS, i-TLCI, i-TM-30-20). Kwiphepha ngalinye lemveliso, uya kufumana iingxelo zefotometric ezibonisa zonke ezi zifundo.
Ukuthelekiswa kwezibane eziPhezulu zeCRI ze-LED Strip
Ngezantsi uza kubona uthelekiso phakathi kokukhanya (lumens ngenyawo) yemveliso nganye. Sisoloko sifumaneka ukukunceda ekukhetheni imveliso efanelekileyo ngokunjalo.
