Inkomba yokunikeza umbala we-LED

Abantu abaningi ngokwengeziwe ekukhetheni izibani kanyeizibani, umqondo wenkomba yokunikeza umbala ezindleleni zokukhetha.

Ngokusho kwencazelo ethi “Izindinganiso Zokuklama Ukukhanya Kwezakhiwo”, ukudweba kombala kubhekisela emthonjeni wokukhanya uma kuqhathaniswa nomthombo wokukhanya ojwayelekile obhekiselwe kuwo, umthombo wokukhanya uveza izici zombala wento. Inkomba yokudweba kombala iyisilinganiso sokudweba kombala womthombo wokukhanya, okuvezwa njengezinga lokuvumelana phakathi kombala wento ngaphansi komthombo wokukhanya olinganisiwe nombala wento ngaphansi komthombo wokukhanya ojwayelekile obhekiselwe kuwo.

IKhomishini Yomhlaba Wonke Yokukhanyisa (i-CIE) ibeke inkomba yokunikeza umbala yokukhanya kwelanga ku-100, futhi yabeka imibala yokuhlola engu-15, isebenzisa u-R1 ~ R15 ukukhombisa inkomba yokubonisa yale mibala engu-15 ngokulandelana. Ingakwazi ukuveza kahle umbala wokuqala wezinto ezidingekayo ukuze isebenzise inkomba yokunikeza umbala ephezulu (i-Ra) yomthombo wokukhanya, inani layo liseduze no-100, ukunikezwa kombala okungcono kakhulu.

Inkomba yokunikeza umbala ejwayelekile, thatha izinhlobo ze-R1 ~ R8 zenkomba yokunikeza umbala ejwayelekile yenani elimaphakathi, eqoshwe njengo-Ra, echaza ukuboniswa kombala womthombo wokukhanya. Inkomba yokunikeza umbala ekhethekile ekhethiwe izinhlobo ze-R9 ~ R15 zamasampula ombala ajwayelekile enkomba yokunikeza umbala, eqoshwe njengo-Ri.

Ngokuvamile sithi inkomba yokunikeza umbala ivame ukubhekisela kunkomba yokunikeza umbala evamile, okungukuthi, inani likaRa, ngokusho "kweZinga Lokuklama Ukukhanyisa Kwezakhiwo," okuhlinzekwa yi-Ra okungenani engu-80, kodwa ngokombono wobungcweti, sifuna futhi ukucabangela inkomba yokunikeza umbala ekhethekile.

Phakathi kwazo, inkomba ekhethekile yokunikeza umbala i-R9 yikhono lokubonisa obomvu ogcwele, lapho uthengaIzibani ze-LEDfuthiizibanikudingeka sinake kakhulu inani lika-R9. Uma inani lika-R9 liphakeme, kulapho umbala wezithelo, izimbali, inyama, njll. ubonakala ungokoqobo khona. Kuncishisiwe. Uma ukukhanya okubomvu kungekho ekukhanyeni, kuzothinta ikhwalithi yokukhanya kwendawo yokukhanya. Ngakho-ke kuphela uma u-Ra no-R9 benamanani aphezulu ngesikhathi esifanayo, ukuvezwa kombala okuphezuluIzibani ze-LEDkungaqinisekiswa.

Uma sibhekisela ekuchazweni kukazwelonke, lapho i-Ra ≥ 80 kanye ne-R9 ≥ 0 yezibani, ingahlangabezana ngokuyisisekelo nenkomba yokunikeza umbala edingekayo emisebenzini yansuku zonke.

Kufanele kuqashelwe ukuthi abaningiIzibani ze-LEDemakethe manje sezithengiswa ngamanani aphansi e-R9, ngakho-ke udinga ukuhlola ngokucophelelaisibaniukukhetha. Ngaphezu kwalokho, uma izidingo zenkomba yokubonisa umbala ziphezulu, ungakhetha izibani ze-Ra ≥ 90, R9 ≥ 70.

Inkomba yokubonisa umbala ephansi kakhulu izothinta amehlo ethu ekubonweni kombala wento, okuholela ekwehleni noma ekwehleni kwekhono lokubona umbala, isikhathi eside emthonjeni wokukhanya ongabonakali kahle, ukuzwela kweseli le-cone yeso lomuntu nakho kuzoncishiswa, kube lula ukuletha ukukhathala kokubona, futhi kubangele ngisho ne-myopia.

Ngakho-ke, ukukhetha izibani ezinenkomba yokubonisa imibala ephezulu kungavikela amehlo ethu futhi kusilethele indawo yokukhanya ekhululekile ngenkathi kuthuthukiswa ukukhiqizwa kombala kwezinto.
