1. I-Luminous Flux (F)
Isimbuku samandla akhutshwa ngumthombo wokukhanya kwaye afunyanwa ngamehlo omntu yi-luminous flux (iyunithi: lm(lumen)). Ngokubanzi, amandla aphezulu ohlobo olufanayo lwesibane, kokukhona i-luminous flux inkulu. Umzekelo, i-luminous flux yesibane esiqhelekileyo se-incandescent esingama-40 yi-350-470Lm, ngelixa i-luminous flux yesibane esiqhelekileyo se-40W straight tube fluorescent imalunga ne-28001m, elilixesha eli-6 ~ 8 lesibane esikhanyayo.
2. Ubunzulu obukhanyayo (I)
Ukukhanya okuphuma kumthombo wokukhanya kwi-unit solid angle kwicala elithile kubizwa ngokuba yi-luminous intensity yomthombo wokukhanya kuloo ndlela, kwaye ngokungathanga ngqo kubizwa ngokuba yi-luminous intensity (iyunithi yi-cd (candela)), 1cd=1m/1s.
3.Ukukhanya (E)
Ukukhanya okukhanyayo okufumaneka ngeyunithi nganye yendawo ekhanyisiweyo kubizwa ngokuba yi-illuminance (iyunithi yi-1x（lux）, oko kukuthi, i-11x=1lm/m². Ukukhanya komhlaba emini kunye nokukhanya kwelanga okunamandla ehlotyeni kumalunga ne-5000lx, ukukhanya komhlaba ngemini enelanga ebusika kumalunga ne-20001x, kwaye ukukhanya komhlaba ebusuku benyanga ecacileyo kumalunga ne-0.2lX.
4.Ukukhanya (L)
Ukukhanya komthombo wokukhanya kwicala elithile, iyunithi yi-nt (nits), kukukhanya okukhanyayo okukhutshwa yindawo eqikelelweyo yeyunithi kunye ne-engile eqinileyo yomthombo wokukhanya kuloo ndlela. Ukuba yonke into ithathwa njengomthombo wokukhanya, ukukhanya kuchaza ukukhanya komthombo wokukhanya, kwaye ukukhanya kuphatha yonke into njengento ekhanyisiweyo. Sebenzisa ibhodi yokhuni ukubonisa. Xa umqadi othile wokukhanya ubetha ibhodi yokhuni, kuthiwa ibhodi inokukhanya okungakanani, kwaye ibhodi ibonakalisa ukukhanya okungakanani emehlweni omntu, kuthiwa ibhodi inokukhanya okungakanani, oko kukuthi, ukukhanya kuyafana nokukhanya okuphindaphindwe kukukhanya, kwindawo enye kwigumbi elinye, iqhekeza lelaphu elimhlophe kunye neqhekeza lokukhanya. Ukukhanya kwemarike emnyama kuyafana, kodwa ukukhanya kwahlukile.
5.Ukusebenza Okukhanyayo Komthombo Wokukhanya
Umlinganiselo we-flux iyonke ekhanyayo ekhutshwa ngumthombo wokukhanya kumandla ombane (w) asetyenziswa ngumthombo wokukhanya ubizwa ngokuba yi-Luminous efficiency yomthombo wokukhanya, kwaye iyunithi yi-lumens/watt (Lm/W)
6.Ubushushu boMbala (i-CCT)
Xa umbala wokukhanya okhutshwa ngumthombo wokukhanya usondele kumbala okhutshwa ngumzimba omnyama kubushushu obuthile, ubushushu bomzimba omnyama bubizwa ngokuba bubushushu bombala (CCT) bomthombo wokukhanya, kwaye iyunithi yi-K. Imithombo yokukhanya enobushushu bombala obungaphantsi kwe-3300K inombala obomvu kwaye inika abantu imvakalelo efudumeleyo. Xa ubushushu bombala budlula i-5300K, umbala uba luhlaza okwesibhakabhaka kwaye unika abantu imvakalelo epholileyo. Ngokubanzi, imithombo yokukhanya enobushushu bombala obungaphezulu kwe-4000K isetyenziswa kwiindawo ezinobushushu obuphezulu. Kwiindawo eziphantsi, sebenzisa imithombo yokukhanya engaphantsi kwe-4000K.
7.Isalathisi Sokuhombisa Umbala (Ra)
Zombini izibane zelanga kunye nezibane ze-incandescent zikhanyisa i-spectrum eqhubekayo. Izinto zibonisa imibala yazo yokwenyani phantsi kokukhanya kwelanga elikhulu kunye nezibane ze-incandescent, kodwa xa izinto zikhanyiswa zizibane zegesi ezikhutshwa yi-spectrum engaguqukiyo, umbala uya kuba namanqanaba ahlukeneyo okuGxothwa, inqanaba lomthombo wokukhanya kumbala wokwenyani wento liba ngumbala womthombo wokukhanya. Ukuze kulinganiswe umzobo wombala womthombo wokukhanya, ingcamango yesalathisi sombala iyaziswa. Ngokusekelwe kukukhanya okuqhelekileyo, isalathisi sombala sichazwa njenge-100. Isalathisi sombala weminye imithombo yokukhanya singaphantsi kwe-100. Isalathisi sombala sichazwa yiRa. Okukhona ixabiso likhulu, kokukhona umbala womthombo wokukhanya ungcono.
8.Umyinge woBomi
Ixesha eliqhelekileyo lobomi libhekisa kwinani leeyure apho i-50% yezibane ezikwiqela lezibane zikhanyisa xa zonakele.
9.Ubomi bezoqoqosho
Ubomi bezoqoqosho bubhekisa kwinani leeyure xa imveliso yemitha edibeneyo incitshiswa ukuya kumlinganiselo othile, kuthathelwa ingqalelo umonakalo webhalbhu kunye nokuncitshiswa kwemveliso yemitha. Umlinganiselo yi-70% kwimithombo yokukhanya yangaphandle kunye ne-80% kwimithombo yokukhanya yangaphakathi.
10.Ukusebenza kakuhle okukhanyayo
Ukusebenza kakuhle kokukhanya komthombo wokukhanya kubhekisa kumlinganiselo wokukhanya okukhanyayo okukhutshwa ngumthombo wokukhanya kumandla ombane u-P asetyenziswa ngumthombo wokukhanya.
11.Ukukhanya okuqaqambileyo
Xa kukho izinto ezikhanyayo kakhulu kwindawo yokujonga, kuya kuba nzima ukubona, okubizwa ngokuba yi-dazzle light. I-dazzle light yinto ebalulekileyo echaphazela umgangatho wemithombo yokukhanya.
