Ukuqonda i-CRI kunye ne-lumens

Njengeminye imiba emininzi yesayensi yemibala, kufuneka sibuyele kumandla okukhanya okubonakalayo komthombo wokukhanya.
I-CRI ibalwa ngokujonga i-spectrum yomthombo wokukhanya kwaye emva koko ifanise kwaye ithelekise i-spectrum enokuthi ibonise isethi yeesampuli zemibala yovavanyo.
I-CRI ibala ukukhanya kwemini okanye umzimba omnyama we-SPD, ngoko ke i-CRI ephezulu ibonisa ukuba ukukhanya okukhanyayo kufana nokukhanya kwemini yendalo (iiCCT eziphezulu) okanye ukukhanya kwe-halogen / incandescent (ii-CCT eziphantsi).

Ukukhanya komthombo wokukhanya kuchazwa ngokuphuma kwayo okukhanyayo, okulinganiswa kwii-lumens. Ukukhanya, kwelinye icala, kukwakhiwa komntu ngokupheleleyo! Kumiselwa ngamaza obude apho amehlo ethu anovelwano kakhulu kunye nobungakanani bamandla okukhanya akhoyo kuloo maza obude. Sibiza i-ultraviolet kunye ne-infrared wavelengths "engabonakaliyo" (oko kukuthi, ngaphandle kokukhanya) ngenxa yokuba amehlo ethu "awathathi" la maza okukhanya njengokukhanya okubonakalayo, kungakhathaliseki ukuba angakanani amandla akhoyo kuwo.
Umsebenzi wokuKhanya

Izazinzulu ekuqaleni kwenkulungwane yamashumi amabini ziye zavelisa iimodeli zeenkqubo zokubona komntu ukuqonda ngcono indlela okwenzeka ngayo ukuqaqamba, kwaye umgaqo osisiseko osemva kwawo ngumsebenzi wokukhanya, ochaza unxulumano phakathi kobude obungamaza kunye nokubonwa kokukhanya.

Igophe elityheli limele umsebenzi oqhelekileyo wefoto (ngasentla)
Ijiko lokukhanya liphezulu phakathi kwe-545-555 nm, ehambelana noluhlu lwamaza ombala we-lime-luhlaza, kwaye yehla ngokukhawuleza kumaza aphezulu nangaphantsi. Ngokucacileyo, amaxabiso okukhanya aphantsi kakhulu ngaphaya kwe-650 nm, ehambelana nombala obomvu wamaza.
Oku kuthetha ukuba umbala obomvu wamaza wamaza, kunye nombala oluhlaza okwesibhakabhaka kunye nombala o-violets, awusebenzi ekwenzeni izinto zibonakale ziqaqambile. Kwelinye icala, amaza aluhlaza natyheli ngawona asebenza kakuhle ekubonakaleni eqaqambile. Oku kunokucacisa ukuba kutheni iivesti zokhuseleko ezibonakala kakhulu kunye neziqaqambisi ngokuqhelekileyo zisebenzisa imibala emthubi/eluhlaza ukuphumeza ukuqaqamba kwazo.
Okokugqibela, xa sithelekisa umsebenzi wokukhanya kunye nokukhanya kwemini yendalo, kufanele kucace ukuba kutheni i-CRI ephezulu, ngakumbi i-R9 yeereds, ingqubana nokuqaqamba. I-spectrum egcweleyo, ebanzi iphantse ihlale inenzuzo xa ulandela i-CRI ephezulu, kodwa i-spectrum emxinwa egxininise kuluhlu lwamaza obude obuluhlaza-tyheli iya kusebenza kakhulu xa ulandela ukusebenza okuphezulu kokukhanya.

Umgangatho wombala kunye ne-CRI ziphantse zibekwe kwindawo ephambili ekufuneni ukusebenza kakuhle kwamandla ngenxa yesi sizathu. Ukuba nobulungisa, ezinye izicelo, ezifanaukukhanya kwangaphandle, inokubeka ugxininiso olukhulu ekusebenzeni kakuhle kunokunikezelwa kombala. Ukuqonda kunye nokuxabisa i-physics echaphazelekayo, ngakolunye uhlangothi, kunokuba luncedo kakhulu ekwenzeni isigqibo esinolwazi ekufakeni ukukhanya.
