Idosi yonyango olukhanyayo ibalwa ngale fomula:
Uxinzelelo lwamandla x Ixesha = Ithamo
Ngethamsanqa, uninzi lwezifundo zamva nje zisebenzisa iiyunithi ezisemgangathweni ukuchaza iprotocol yazo:
Uxinaniso lwaMandla kwi-mW/cm² (i-milliwatts ngesentimitha ephindwe kabini)
Ixesha kwi s (imizuzwana)
Ithamo kwi-J/cm² (Ijowuli ngesentimitha ephindwe kabini)
Kunyango olulula ekhaya, ukuxinana kwamandla ke ngoko yeyona nto iphambili ekufuneka uyazi - ukuba awuyazi, awuyi kuba nakho ukwazi ukuba ungasifaka ixesha elingakanani isixhobo sakho ukuze ufumane ithamo elithile.Ngumlinganiselo nje wokomelela kokukhanya kokukhanya (okanye ukuba zingaphi iifotoni ezikwindawo ethile).
Ngee-LED ze-angled output, ukukhanya kusasazeka njengoko kuhamba, kugubungela indawo ebanzi kunye nebanzi.Oku kuthetha ukuba ubukhulu bokukhanya obunxulumeneyo nakweyiphi na indawo iye iba buthathaka njengoko umgama osuka kumthombo usanda.Umahluko kwii-angles ze-beam kwii-LED nazo zichaphazela ubuninzi bamandla.Umzekelo i-LED ye-3w/10° iya kuvelisa uxinano lwamandla okukhanya ngaphezulu kwe-3w/120° i-LED, eya kuvelisa ukukhanya okubuthathaka kwindawo enkulu.
Uphononongo lonyango olulula lukholisa ukusebenzisa uxinaniso lwamandla oluyi ~10mW/cm² ukuya kuthi ga kwi-max ~200mW/cm².
Ithamo ikuxelela nje ukuba uxinaniso lwamandla lwalucelwe ixesha elingakanani.Ukukhanya okuphezulu kokukhanya kuthetha ukuba kufuneka ixesha elincinci lokufaka isicelo:
I-5mW/cm² ifakwe kwimizuzwana engama-200 inika i-1J/cm².
I-20mW/cm² ifakwe kwimizuzwana engama-50 inika i-1J/cm².
I-100mW/cm² ifakwe kwimizuzwana eyi-10 inika i-1J/cm².
Ezi yunithi ze-mW/cm² kunye nesekondi zinika isiphumo kwi-mJ/cm² – phinda-phinda oko ngo-0.001 ukuze ungene ku-J/cm².Ifomula epheleleyo, kuthathelwa ingqalelo iiyunithi ezisemgangathweni yile:
Umthamo = Ubuninzi bamandla x Ixesha x 0.001
