Ngokuthandwa kobuchwepheshe bokukhanyisa i-LED, abathengi banaka kakhulu ikhwalithi yokukhanya lapho bethenga izibani. I-CRI (inkomba yokunikeza umbala), njengesibonakaliso esibalulekile sokulinganisa ikhono lokunikeza umbala lemithombo yokukhanya, isibe ngenye yemingcele ebalulekile yokwahlulela ukusebenza kwezibani ze-LED. Ngakho-ke, ake sibheke ukuthi iyini i-CRI.
[Incazelo kanye nokubaluleka kwenkomba ye-CRI]:CRI (Inkomba Yokunikeza Umbala)iyinkomba esetshenziswa ukuhlola ikhono lomthombo wokukhanya lokubuyisela umbala wangempela wento. Inani layo lisukela ku-0 kuya ku-100.Uma inani liphakeme, kulapho umbala womthombo wokukhanya ubonakala khona kangcono.I-CRI yokukhanya kwemvelo ingu-100, kuyilapho i-CRI yezibani ze-LED ezisezingeni eliphezulu ingafinyelela ngaphezu kuka-80, kanti imikhiqizo ephezulu ingafinyelela ngisho nangaphezu kuka-95, okungaveza imininingwane yombala wezinto ngendlela engokoqobo.
Ezimweni zokukhanya zasekhaya, zezentengiselwano nezezimboni, izinga le-CRI index lithinta ngqo ulwazi olubonakalayo. Isibonelo, ezindaweni zobuciko, ezitolo zezingubo noma ezindaweni zokulungisa izimonyo, ukukhanya okuphezulu kwe-CRI kungabuyisela ngokunembile imibala yangempela yemibukiso futhi kugweme umehluko wemibala; ezindaweni zasekhaya, izibani eziphezulu ze-CRI zingenza ukudla, ifenisha kanye nemibala yokuhlobisa ikhanye kakhulu futhi ithuthukise induduzo. Ngokuphambene nalokho, imithombo yokukhanya ephansi ye-CRI ingabangela ukuphambuka kombala, futhi ukusetshenziswa isikhathi eside kungabangela nokukhathala kokubona.
Ukudweba imibala kanye nempilo: Uma uhlala ngaphansi komthombo wokukhanya onombala ongabonakali kahle isikhathi eside, kulula ukubangela ukukhathala kwamehlo ngisho ne-myopia. Inkomba yombala wokukhanya ephansi kakhulu ekilasini ithinta amehlo abantu ukuze babone umbala wezinto, ukuze izinto zingakwazi ukukhombisa imibala yazo yangempela.
Ukudweba nokukhanyisa kombala: Inkomba yokubonisa umbala yomthombo wokukhanya kanye nokukhanya ndawonye kunquma ukucaca okubonakalayo kwendawo ezungezile. Kukhona ibhalansi phakathi kokukhanyisa kanye nenkomba yokubonisa umbala. Uma usebenzisa isibani esinenkomba yokubonisa umbala i-Ra>90 ukukhanyisa ihhovisi, ukukhanya kungancishiswa ngaphezu kuka-25% ngokweneliseka kokubukeka kwalo uma kuqhathaniswa nehhovisi elikhanyiswa isibani esinenkomba yokubonisa umbala ephansi (Ra<60).
Ngakho-ke, kubaluleke kakhulu ukukhetha inani elifanele le-CRI. Ekukhanyeni okuvamile kwasekhaya, izibani ze-LED ezine-CRI ≥ 80 zingakhethwa, kuyilapho izindawo ezinezidingo eziqinile zombala (njengezitudiyo zokuklama nezindawo zezokwelapha) kufanele zikhethe imikhiqizo
nge-CRI ≥ 90. Ngaphezu kwalokho, abathengi kufanele baqaphele ukuthi i-CRI akuyona yodwa indinganiso, futhi kuyadingeka futhi ukucabangela amapharamitha afana nokushisa kombala kanye nokusebenza kahle kokukhanya.
Njengamanje, izibani ze-LED ezine-CRI ephezulu ziyadingeka ezindaweni eziningi. Ngokwefilosofi ye-LIPER: i-CRI engaphezu kuka-80 iyindawo yokuqala nje. Lokho i-LIPER efuna ukukwenza ukuqinisekisa ukuthi wonke umsebenzisi angasebenzisa izibani ze-LED ezine-CRI engaphezu kuka-90!
Esikhathini sokukhanya kwe-LED, inkomba ye-CRI isibe yindlela ebalulekile yokulinganisa ikhwalithi yokukhanya. Lapho bethenga, abathengi kufanele bakhethe imikhiqizo enemibala emihle kakhulu ngokwezidingo zabo ukuze bathole ulwazi lokukhanya olunempilo nolukhululekile.
Yilokhu esifuna ukukukhombisa khona ngokukhanya kwe-LED kochungechunge lwe-Liper MW.
