Indlela Yokukala I-CRI?
1- Ukulinganisa I-CRI Yokukhanya Kwasemini
Udinga ukulandela indlela evamile yemboni ye-CIE ukukala i-CRI yanoma yimuphi umthombo wokukhanya. Lapha, irediyetha yomzimba emnyama enamaphuzu aphelele e-CRI angu-100 ithathwa njengesampula yereferensi. Udinga ukuqhathanisa ukunikezwa kombala womthombo wokuhlola nale sampuli. Ukuze ubale isilinganiso esijwayelekile se-CRI, udinga ukukhetha amasampuli ayizithenjwa ayi-15 ngokucabangela ukushisa kombala yokukhanya okuhloliwe.
I-CIE (1999) ihlele ngezinombolo lawa masampuli ayizethenjwa eshadini Lokuhlola Umbala. Lokhu kuqala nge-TCS01, okubizwa ngokuthi 'I-Light Grayish Red,' futhi iphela nge-TCS15, ebizwa ngokuthi 'isikhumba sase-Asia.' Uma umthombo ohloliwe usondelana kakhulu nesampula yesithenjwa, izinga le-CRI elizoba nalo liyaphakama.
Siqhathanisa imibala ebonisiwe futhi sinqume ngokwefomula umphumela othi “R” wewashi ngalinye lombala.
Inani elingu-R lombala othile libonisa amandla omthombo wokukhanya ukuze anikeze ngokwethembeka lowo mbala othile. Ngakho-ke, ifomula ye-CRI ithatha isilinganiso samanani angu-R ukuze ibonise amandla okunikeza umbala wonke womthombo wokukhanya.
- U-Ra uyisilinganiso senani lika-R1 kuya ku-R8.
- I-AvgR iyinani elimaphakathi lika-R1 kuya ku-R15.
- Inani elikhethekile: R9
Ngokuvamile, esibalweni se-CRI, u-Ra uyisilinganiso sika-R1–R8. Lapha, amanani asuka ku-R9 kuya ku-R15 awabalwa. Nokho, ezinsizeni ezidinga inkomba ephezulu yokunikeza imibala, u-R9 uwukucatshangelwa okubalulekile. Inquma amandla omthombo wokukhanya okubonisa umbala obomvu ngokunembile.

Kodwa-ke, iSeoul Semiconductor ithathe ukukhanya okugcwele kwe-spectrum yaya ezingeni elilandelayo nayo I-SunLike Natural Spectrum LED Technology. Lobu buchwepheshe bathuthukiswa ngokubambisana ngenhlanganisela yobuchwepheshe be-Seoul Semiconductor optical semiconductor kanye nobuchwepheshe be-Toshiba Materials' TRI-R.
Izibani eziklanywe ngalobu buchwepheshe zilingisa ukukhanya kwelanga eduze kakhulu, zinikeza ukunemba kombala okunembile njengoba nje ubona emini yemvelo. Ngakho, ama-SunLike LED aqinisekisa inkomba ephezulu yokunikeza umbala (CRI) engu-98+.
Amathrendi Akusasa Ekunikezeni Umbala
1. Ukukhula Okudumile Kwamamethrikhi Athuthukile
I-CRI inemikhawulo ethile embozwa kalula u-matrices njenge-TM-30 ne-CQS. Ngakho-ke, ukuhlola ukunikezwa kombala, lawa mayunithi azoduma kakhulu kune-CRI.
2. Ukukhanyisa Okuphakathi Kwabantu
Ukukhanyisa okuphakathi kwabantu kuya ngokuduma njengoba kuklanyelwe ukunikeza ukukhanya okunethezekile. Ngakho-ke, uzothola isilinganiso esiphezulu se-CRI kuzo zonke izinhlobo zokukhanya okugxile kumuntu ukuze kuqinisekiswe ukunethezeka okubonakalayo.
3. Smart Lighting Solutions
Izibani ezihlakaniphile ezinezici ezithuthukisiwe zisiza izinketho ze-CCT ezilungisekayo. Kodwa-ke, izinketho ezinjalo zokwenza ngokwezifiso zizofika maduze ku-CRI, futhi.
Imibuzo Evame Ukubuzwa
Ukufaka phezulu
Ukufingqa, ukucabangela i-CRI ephezulu kubalulekile ukuze uqinisekise umbono ofanele wombala wendawo ekuzungezile. Izibani ze-CRI eziphansi ngeke zigcine ngokuthinta ukubukeka kombala kuphela kodwa futhi zibangele ukungakhululeki futhi ziphazamise ukukhiqiza komsebenzi. Ngakho-ke, kufanele ucabangele izidingo zesicelo sakho bese ukhetha i-CRI efanele ulandela imihlahlandlela engenhla.
Kodwa-ke, ukuze uqinisekise ukuthi uthenga ukukhanya kwekhwalithi ngesilinganiso esithembekile se-CRI, i-LEDYi iyisixazululo sakho othembeke kakhulu. Konke okwethu ukukhanya okugcwele kwe-LED strip ane-CRI ephezulu, i-Ra> 97. Njengoba siyinkampani eqinisekisiwe, akudingeki ukhathazeke ngokunemba kwayo. Ngakho-ke, kungani usalinda?
