Isalathisi sokuboniswa kombala we-LED

Abantu abaninzi ngakumbi ekukhetheni izibaneizibane, ingcamango yesalathisi sokuboniswa kombala kwiikhrayitheriya zokukhetha.

Ngokwenkcazo "yeMigangatho yoYilo lweZibane zoLwakhiwo", ukuboniswa kombala kubhekisa kumthombo wokukhanya xa kuthelekiswa nomthombo wokukhanya oqhelekileyo, umthombo wokukhanya ubonisa iimpawu zombala wento. Isalathisi sokuboniswa kombala sisilinganiselo sokuboniswa kombala komthombo wokukhanya, esichazwa njengomlinganiselo wokuhambelana phakathi kombala wento phantsi komthombo wokukhanya olinganisiweyo kunye nombala wento phantsi komthombo wokukhanya oqhelekileyo.

IKhomishini yeHlabathi yoKukhanyiswa (i-CIE) ibeke isalathisi sokuboniswa kombala welanga kwi-100, yaza yabeka imibala yovavanyo eli-15, isebenzisa i-R1 ~ R15 ukubonisa isalathisi sokuboniswa kwezi mibala zili-15 ngokulandelelana. Ingabonakalisa ngokuchanekileyo umbala wokuqala wezinto ezifunekayo ukuze isebenzise isalathisi sokuboniswa kombala ophezulu (i-Ra) somthombo wokukhanya, ixabiso layo lisondele kwi-100, eyona nkcazelo yombala ibalaseleyo.

Isalathisi sombala ngokubanzi, thabatha iintlobo ze-R1 ~ R8 zesalathisi sombala esiqhelekileyo sexabiso eliphakathi, ezirekhodwe njenge-Ra, ezichaza umzobo wombala womthombo wokukhanya. Isalathisi sombala esikhethekileyo esikhethiweyo si-R9 ~ R15 iintlobo zeesampuli zombala ezisemgangathweni zesalathisi sombala, ezirekhodwe njenge-Ri.

Ngokwesiqhelo sithi isalathisi sombala sidla ngokubhekisa kwisalathisi sombala ngokubanzi, oko kukuthi, ixabiso likaRa, ngokwe "Migangatho yoYilo lweZibane zoLwakhiwo," amalungiselelo e-Ra ubuncinci obuyi-80, kodwa ngokwembono yobungcali, sifuna nokuqwalasela isalathisi sombala okhethekileyo.

Phakathi kwazo, isalathisi sombala okhethekileyo i-R9 kukukwazi ukubonisa ubomvu obomileyo, xa uthengaIzibane ze-LEDkwayeizibanekufuneka unikele ingqalelo ekhethekileyo kwixabiso le-R9. Okukhona ixabiso le-R9 liphezulu, kokukhona umbala weziqhamo, iintyatyambo, inyama, njl.njl. Uncitshisiwe. Ukuba isibane esibomvu asifumaneki ekukhanyeni, oko kuya kuchaphazela umgangatho wokukhanya kwendawo ekukhanyeni. Ke kuphela xa i-Ra kunye ne-R9 zinamaxabiso aphezulu ngaxeshanye, umbala ophezulu ubonakala.Izibane ze-LEDinokuqinisekiswa.

Ngokubhekiselele kwiinkcukacha zesizwe, xa izibane zeRa ≥ 80 kunye neR9 ≥ 0, ngokusisiseko zinokuhlangabezana nesalathisi sombala esifunekayo kwimisebenzi yemihla ngemihla.

Kufuneka kuqatshelwe ukuba uninziIzibane ze-LEDezithengiswayo ngoku zithengiswa ngexabiso eliphantsi le-R9, ngoko ke kufuneka uyihlole ngononopheloisibaneukhetho. Ukongeza, ukuba iimfuno zesalathisi sokuboniswa kombala ziphezulu, ungakhetha izibane zeRa ≥ 90, R9 ≥ 70.

Isalathisi sokuboniswa kombala esiphantsi kakhulu siya kuchaphazela amehlo ethu ekubonweni kombala wento, nto leyo ekhokelela ekwehleni okanye ekwehleni kwamandla okubonwa kombala, ixesha elide kumthombo wokukhanya ongekho mhle, uvakalelo lweeseli zekhoni zeliso lomntu nalo luya kuncipha, kube lula ukuzisa ukudinwa kokubona, kwaye kubangele nokuba ne-myopia.

Ngoko ke, ukukhetha izibane ezinemibala ephezulu kunokukhusela amehlo ethu kwaye kusizise indawo ekhanyayo ekhululekileyo ngelixa kuphucula ukuveliswa kombala wezinto.
