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 wokunikezelwa kombala (Ra) womthombo 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 sithetha ukuba isalathiso sokwenza umbala ngokuqhelekileyo sibhekisela kwisalathiso sombala jikelele, oko kukuthi, ixabiso likaRa, ngokwe "Imigangatho yoYilo loLwakhiwo loLwakhiwo," izibonelelo zeRa ubuncinane ze-80, kodwa kwimbono yobungcali, sifuna kwakhona ukuqwalasela isalathisi esikhethekileyo sokunikezelwa kombala.

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 wokunikezelwa kwesalathiso kuya kuchaphazela amehlo ethu ekuqaphelisweni kombala wento, okukhokelela ekwehleni okanye ekwehleni kwesakhono sokuqondwa kombala, ixesha elide kumthombo wokukhanya wombala ohlwempuzekileyo, uvakalelo lweseli yeso lomntu nalo luya kuncitshiswa, lula ukuzisa ukudinwa okubonakalayo, kwaye nokuba kubangele i-myopia.

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