Inkomba yokunikeza umbala we-LED

Abantu abaningi ngokwengeziwe ekukhetheni izibani kanyeizibani, umqondo wenkomba yokunikeza umbala kumbandela wokukhetha.

Ngokusho kwencazelo "Amazinga Omklamo Wokukhanya Wokwakhiwa", ukunikezwa kombala kubhekisela kumthombo wokukhanya uma kuqhathaniswa nomthombo wokukhanya ojwayelekile wereferensi, umthombo wokukhanya uveza izici zombala wento.Inkomba yokunikeza umbala isilinganiso sombala womthombo wokukhanya, ovezwa njengezinga lokuvumelana phakathi kombala wento engaphansi komthombo wokukhanya olinganiselwe kanye nombala wento engaphansi komthombo wokukhanya ojwayelekile wereferensi.

I-International Commission on Illumination (CIE) yabeka inkomba enikeza umbala yokukhanya kwelanga ku-100, futhi yabeka imibala yokuhlola engu-15, isebenzisa u-R1~R15 ukuze ibonise inkomba yesibonisi yale mibala engu-15 ngokulandelanayo.Ingakwazi ukuveza kahle umbala wangempela wesidingo sokusebenzisa inkomba enikeza umbala ophezulu (Ra) yomthombo wokukhanya, inani layo lisondele ku-100, ukunikezwa kombala okungcono kakhulu.

Inkomba evamile yokunikeza umbala, thatha izinhlobo ezingu-R1 ~ R8 zenkomba evamile yokunikeza umbala yenani elimaphakathi, elirekhodwe njengo-Ra, elibonisa ukunikezwa kombala womthombo okhanyayo.Inkomba ekhethekile yokunikeza imibala ekhethiwe engu-R9 ~ R15 izinhlobo zamasampuli ombala ojwayelekile wenkomba yokunikeza umbala, eqoshwe ngokuthi Ri.

Ngokuvamile sithi inkomba yokunikeza umbala ngokuvamile ibhekisela kunkomba evamile yokunikeza umbala, okungukuthi, inani lika-Ra, ngokuya “Ngamazinga Omklamo Wokukhanyisa Kwezakhiwo,” izinhlinzeko zobuncane be-Ra obungu-80, kodwa kusukela endaweni yobuchwepheshe. buka, sifuna futhi ukucabangela inkomba ekhethekile yokunikeza umbala.

Phakathi kwazo, inkomba ekhethekile yokunikeza umbala i-R9 yikhono lokubonisa okubomvu okugcwele lapho uthengaIzibani ze-LEDfuthiizibanikudingeka sinake ngokukhethekile inani lama-R9.Uma liphakeme inani lika-R9, umbala wezithelo, izimbali, inyama, njll ubonakala ungokoqobo nakakhulu.Uma isibani esibomvu singekho ekukhanyeni, sizothinta ikhwalithi yokukhanya kwemvelo yokukhanya.Ngakho-ke kuphela uma i-Ra ne-R9 inamanani aphezulu ngesikhathi esifanayo, ukunikezwa kombala ophezulu weIzibani ze-LEDingaqinisekiswa.

Ibhekisela ekucacisweni kwezwe, lapho i-Ra ≥ 80 ne-R9 ≥ 0 yezibani, ingahlangabezana ngokuyisisekelo nenkomba yokunikeza umbala edingekayo emisebenzini yansuku zonke.

Kufanele kuqashelwe ukuthi abaningiIzibani ze-LEDemakethe manje athengiswa ngamavelu e-R9 angemahle, ngakho-ke udinga ukuhlola ngokucophelelaisibaniukukhetha.Ngaphezu kwalokho, uma izidingo zenkomba yokunikeza umbala ziphezulu, ungakhetha amalambu e-Ra ≥ 90, R9 ≥ 70.

Inkomba ephansi kakhulu yokunikeza umbala wokukhanyisa izothinta amehlo ethu ekuqashelweni kombala wento, okuholela ekwehleni noma ekwehleni kwekhono lokuqaphela umbala, isikhathi eside emthonjeni wokukhanya onikeza umbala ompofu, ukuzwela kwekhoni yeso lomuntu nakho kuzoncipha, kube lula. ukuletha ukukhathala okubukwayo, futhi kubangele i-myopia.

Ngakho-ke, ukukhetha amalambu anenkomba ephezulu yokunikeza umbala kungavikela amehlo ethu futhi kusilethele indawo yokukhanya enethezekile kuyilapho kuthuthukisa ukukhiqizwa kombala kwezinto.
