Ukuqonda i-CRI namalumens

Njengezinye izici eziningi zesayensi yombala, kufanele sibuyele ekusabalaliseni amandla e-spectral omthombo wokukhanya.
I-CRI ibalwa ngokuhlola i-spectrum yomthombo wokukhanya bese ilingisa futhi iqhathanise i-spectrum engabonisa isethi yamasampuli ombala wokuhlola.
I-CRI ibala ukukhanya kwemini noma umzimba omnyama we-SPD, ngakho i-CRI ephakeme ibonisa ukuthi i-spectrum yokukhanya ifana nokukhanya kwemini yemvelo (ama-CCT aphezulu) noma ukukhanya kwe-halogen/incandescent (ama-CCT aphansi).

Ukukhanya komthombo wokukhanya kuchazwa ngokukhipha kwawo okukhanyayo, okukalwa ngama-lumens. Ukukhanya, ngakolunye uhlangothi, kuwukwakhiwa komuntu ngokuphelele! Kunqunywa ngamaza amaza amehlo ethu azwela kakhulu kuwo kanye nenani lamandla okukhanya akhona kulawo maza obude. Sibiza amaza e-ultraviolet namaza e-infrared “angabonakali” (okungukuthi, ngaphandle kokukhanya) ngoba amehlo ethu “awacoshi” lawa maza obude njengokukhanya okubonwayo, kungakhathaliseki ukuthi angakanani amandla akhona kuwo.
Umsebenzi Wokukhanya

Ososayensi ekuqaleni kwekhulu lamashumi amabili bathuthukise amamodeli wezinhlelo zokubona komuntu ukuze baqonde kangcono ukuthi kwenzeka kanjani ukukhanya okusebenza, futhi isimiso esiyisisekelo ngemuva kwakho umsebenzi wokukhanya, ochaza ubudlelwano phakathi kobude beza nombono wokukhanya.

Ijika eliphuzi limelela umsebenzi ojwayelekile wesithombe (ngenhla)
Ijika lokukhanya lifinyelela phezulu phakathi kuka-545-555 nm, elihambisana nobubanzi be-wavelength bombala oluhlaza okotshani, futhi lehle ngokushesha kumaza amaza aphezulu naphansi. Ngokubalulekile, amanani okukhanya aphansi kakhulu ukudlula u-650 nm, ohambisana namaza ombala obomvu.
Lokhu kusho ukuthi amaza ombala obomvu, kanye namaza ombala oluhlaza okwesibhakabhaka noviolet, awasebenzi ekwenzeni izinto zibonakale zigqamile. Ngakolunye uhlangothi, amaza amaza aluhlaza naphuzi yiwona asebenza kahle kakhulu ekubonakaleni egqamile. Lokhu kungachaza ukuthi kungani amavesti okuphepha abonakala phezulu kanye nezinto ezigqamisayo ngokuvamile zisebenzisa imibala ephuzi/eluhlaza okotshani ukuze zifinyelele ukukhanya kwazo okuhlobene.
Okokugcina, uma siqhathanisa umsebenzi wokukhanya ne-spectrum yokukhanya kwemvelo kwemini, kufanele kucace ukuthi kungani i-CRI ephezulu, ikakhulukazi i-R9 yokubomvu, ingqubuzana nokukhanya. I-spectrum egcwele, ebanzi cishe ihlale inenzuzo uma ulandela i-CRI ephezulu, kodwa i-spectrum encane egxile kububanzi be-wavelength obuluhlaza-ophuzi izosebenza kakhulu uma ilandela ukusebenza ngempumelelo kokukhanya okuphezulu.

Ikhwalithi yombala kanye ne-CRI cishe kuhlale kwehliswa kuqala ekuphishekeleni ukusebenza kahle kwamandla ngenxa yalesi sizathu. Ukuze sibe nobulungiswa, ezinye izicelo, ezifanaukukhanya kwangaphandle, ingase igcizelele kakhulu ukusebenza kahle kunokunikezwa kombala. Ukuqonda nokwazisa kwe-physics ehilelekile, ngakolunye uhlangothi, kungaba usizo kakhulu ekwenzeni isinqumo esinolwazi ekufakweni kokukhanyisa.
