Ukuqonda i-CRI kanye ne-lumens

Njengakwezinye izici eziningi zesayensi yombala, kumelwe sibuyele ekusatshalalisweni kwamandla e-spectral komthombo wokukhanya.
I-CRI ibalwa ngokuhlola i-spectrum yomthombo wokukhanya bese ilingisa futhi iqhathanise i-spectrum ezobonisa isethi yamasampula ombala wokuhlola.
I-CRI ibala ukukhanya kwelanga noma umzimba omnyama i-SPD, ngakho-ke i-CRI ephezulu ikhombisa ukuthi ukukhanya kwe-spectrum kufana nokukhanya kwelanga kwemvelo (ama-CCT aphezulu) noma ukukhanya kwe-halogen/incandescent (ama-CCT aphansi).

Ukukhanya komthombo wokukhanya kuchazwa ngokukhishwa kwawo okukhanyayo, okulinganiswa ngama-lumens. Ukukhanya, ngakolunye uhlangothi, kungumuntu ngokuphelele! Kunqunywa ngama-wavelength amehlo ethu azwela kakhulu kuwo kanye nenani lamandla okukhanya akhona kulawo ma-wavelength. Sibiza ama-wavelength e-ultraviolet kanye ne-infrared ngokuthi “angabonakali” (okungukuthi, ngaphandle kokukhanya) ngoba amehlo ethu “awathathi” la ma-wavelength njengokukhanya okubonwayo, kungakhathaliseki ukuthi angakanani amandla akhona kuwo.
Umsebenzi Wokukhanya

Ososayensi ekuqaleni kwekhulu lama-20 bathuthukisa amamodeli ezinhlelo zokubona komuntu ukuze baqonde kangcono ukuthi lesi simo sokukhanya sisebenza kanjani, futhi isimiso esiyisisekelo ngemuva kwaso umsebenzi wokukhanya, ochaza ubudlelwano phakathi kobude be-wavelength kanye nokubona ukukhanya.

Ijika eliphuzi limelela umsebenzi ojwayelekile we-photopic (ngenhla)
Ijika lokukhanya lifinyelela ukuphakama okuphakathi kuka-545-555 nm, okuhambisana nobubanzi bobude bokukhanya obuluhlaza okotshani, futhi lehla ngokushesha kuma-wavelength aphezulu naphansi. Ngokubalulekile, amanani okukhanya aphansi kakhulu ngaphezu kuka-650 nm, okuhambisana nama-wavelength ombala obomvu.
Lokhu kusho ukuthi ubude besikhathi obubomvu, kanye nobude besikhathi obuluhlaza okwesibhakabhaka no-violet, abusebenzi kahle ekwenzeni izinto zibonakale zikhanya. Ububanzi besikhathi obuluhlaza nophuzi, ngakolunye uhlangothi, busebenza kahle kakhulu ekubonakaleni bukhanya. Lokhu kungachaza ukuthi kungani amavesti okuphepha abonakala kakhulu kanye nama-highlighter ngokuvamile asebenzisa imibala ephuzi/eluhlaza ukuze afinyelele ukukhanya kwawo okulinganiselwe.
Okokugcina, uma siqhathanisa umsebenzi wokukhanya ne-spectrum yokukhanya kwelanga kwemvelo, kufanele kucace ukuthi kungani i-CRI ephezulu, ikakhulukazi i-R9 yama-reds, iphikisana nokukhanya. I-spectrum egcwele, ebanzi cishe njalo inenzuzo lapho kulandelwa i-CRI ephezulu, kodwa i-spectrum encane egxile ebangeni lamaza okukhanya okuluhlaza okwesibhakabhaka izosebenza kahle kakhulu lapho kulandelwa ukusebenza kahle okuphezulu kokukhanya.

Ikhwalithi yombala kanye ne-CRI cishe njalo kubekwa phansi njengento eza kuqala ekuphishekeleni ukusebenza kahle kwamandla ngenxa yalesi sizathu. Ukuze kube nobulungiswa, ezinye izinhlelo zokusebenza, ezifanaukukhanyisa kwangaphandle, kungase kugcizelele kakhulu ukusebenza kahle kunokudweba imibala. Ukuqonda nokwazisa i-physics ehilelekile, ngakolunye uhlangothi, kungaba usizo kakhulu ekwenzeni isinqumo esinolwazi ekufakweni kokukhanyisa.
