Isalathisi sonikezelo lombala we-LED

Abantu abaninzi ngakumbi ekukhetheni izibane kunyeizibane, ingqikelelo yonikezelo lombala kwiikhrayitheriya zokukhetha.

Ngokwenkcazo "yeMigangatho yoYilo loMbane woLwakhiwo", ukunikezelwa kombala kubhekiselele kumthombo wokukhanya xa kuthelekiswa nomthombo wokukhanya oqhelekileyo wereferensi, umthombo wokukhanya ubonisa iimpawu zombala wento.Isalathiso sombala wesalathiso ngumlinganiselo wonikezelo lombala womthombo wokukhanya, ochazwa njengeqondo lokuthotyelwa phakathi kombala wento ephantsi komthombo wokukhanya olinganisiweyo kunye nombala wento phantsi komthombo wokukhanya osemgangathweni wereferensi.

I-International Commission on Illumination (CIE) yamisela isalathiso sombala wokukhanya kwelanga kwi-100, yaza yachaza imibala yovavanyo eli-15, isebenzisa i-R1~R15 ukubonisa isalathisi sale mibala ili-15 ngokulandelelanayo.Iyakwazi ukuchaza ngokuchanekileyo umbala wokuqala wezinto ezifunekayo ukusebenzisa umbala ophezulu wokunikezela ngesalathiso (Ra) somthombo wokukhanya, ixabiso layo lisondele kwi-100, ukunikezelwa kombala ongcono.

Isalathiso sonikezelo lombala ngokubanzi, thatha i-R1 ~ R8 iintlobo zesalathiso sombala esisemgangathweni sexabiso eliphakathi, elirekhodwe njengo-Ra, elibonisa umthombo wokukhanya wonikezelo lombala.Isalathiso esikhethekileyo sonikezelo sombala esikhethiweyo R9 ~ R15 iintlobo zeesampulu zombala eziqhelekileyo zesalathisi sonikezelo sombala, esirekhodwe njengeRi.

Ngokuqhelekileyo sithi isalathiso sonikezelo lombala sihlala sibhekisa kwisalathiso sonikezelo lombala ngokubanzi, oko kukuthi, ixabiso likaRa, ngokwe "Imigangatho yoYilo loLwabiwo lwezoLwakhiwo," izibonelelo zeRa ubuncinci be-80, kodwa ukusuka kwindawo yobuchwephesha. Jonga, sikwafuna ukuqwalasela umbala okhethekileyo wonikezelo index.

Phakathi kwabo, isalathisi esikhethekileyo sombala we-R9 yikhono lokubonisa i-saturated red, xa kuthengwaIzibane ze-LEDkwayeizibanekufuneka kunikwe ingqwalasela eyodwa kwixabiso le-R9.Xa liphezulu ixabiso le-R9, kokukhona umbala weziqhamo, iintyatyambo, inyama, njl. njl.Ukuba ukukhanya okubomvu kulahlekile ekukhanyeni, kuya kuchaphazela umgangatho wokukhanya kwendawo yokukhanya.Ke kuphela xa iRa kunye ne-R9 zinamaxabiso aphezulu ngexesha elinye, unikezelo lombala ophezulu weIzibane ze-LEDinokuqinisekiswa.

Ngokubhekiselele kwinkcazo yelizwe, xa i-Ra ≥ 80 kunye ne-R9 ≥ 0 yezibane, inokuhlangabezana ngokusisiseko nesalathisi sombala ofunekayo kwimisebenzi yemihla ngemihla.

Kufuneka kuqatshelwe ukuba abaninziIzibane ze-LEDkwimarike ngoku zithengiswa ngexabiso elibi le-R9, ngoko ke kufuneka ukhuselwe ngononopheloisibaneukhetho.Ukongeza, ukuba iimfuno zesalathisi sombala ziphezulu, ungakhetha iRa ≥ 90, R9 ≥ 70 izibane.

Ukukhanya okuphantsi kakhulu kombala wokunikezela ngesalathiso kuya kuchaphazela amehlo ethu ekuqaphelisweni kombala wento, okukhokelela ekwehleni okanye ekwehleni kobuchule bokuqatshelwa kombala, ixesha elide kumthombo wokukhanya ongemhle wombala, uvakalelo lweseli yeso lomntu luya kuncitshiswa, lula. ukuzisa ukudinwa okubonakalayo, kunye nokubangela i-myopia.

Ke ngoko, ukukhetha izibane ezinesalathiso sombala ophezulu kunokukhusela amehlo ethu kwaye kusizisele indawo yokukhanya ekhululekileyo ngelixa uphucula ukuvela kombala wezinto.
