1. I-Luminous Flux (F)
Isamba samandla akhishwa umthombo wokukhanya futhi atholwa ngamehlo omuntu yi-luminous flux (iyunithi: lm(lumen)). Ngokuvamile, uma amandla ohlobo olufanayo lwesibani ephezulu, i-luminous flux inkulu. Isibonelo, i-luminous flux yesibani esijwayelekile esingu-40 i-incandescent ingu-350-470Lm, kanti i-luminous flux yesibani esijwayelekile esingu-40W i-straight tube fluorescent cishe ingu-28001m, okuyizikhathi ezingu-6~8 zesibani esikhanyayo.
2. Ukuqina Okukhanyayo (I)
Ukukhanya okukhanyayo okukhishwa umthombo wokukhanya ekhoneni eliqinile leyunithi ohlangothini oluthile kubizwa ngokuthi ukuqina okukhanyayo komthombo wokukhanya kulolo hlangothi, futhi ngokungaqondile kubizwa ngokuthi ukuqina okukhanyayo (iyunithi yi-cd (candela)), 1cd=1m/1s.
3.Ukukhanya(E)
Ukukhanya okukhanyayo okutholwa ngeyunithi ngayinye yendawo ekhanyisiwe kubizwa ngokuthi ukukhanya (iyunithi ingu-1x（lux）, okungukuthi, 11x=1lm/m². Ukukhanya komhlabathi emini nokukhanya kwelanga okunamandla ehlobo kungaba ngu-5000lx, ukukhanya komhlabathi ngosuku olunelanga ebusika kungaba ngu-20001x, kanti ukukhanya komhlabathi ebusuku benyanga ecacile kungaba ngu-0.2lX.
4.Ukukhanya (L)
Ukukhanya komthombo wokukhanya ohlangothini oluthile, iyunithi ingu-nt (nits), ukugeleza okukhanyayo okukhishwa yindawo ebonisiwe yeyunithi kanye ne-engeli eqinile yeyunithi yomthombo wokukhanya kulolo hlangothi. Uma yonke into ibhekwa njengomthombo wokukhanya, khona-ke ukukhanya kuchaza ukukhanya komthombo wokukhanya, futhi ukukhanya kuphatha yonke into njengento ekhanyisiwe. Sebenzisa ibhodi lokhuni ukuze ubonise. Lapho umsebe othile wokukhanya ushaya ibhodi lokhuni, kubizwa ngokuthi ukukhanya okungakanani ibhodi elinakho, nokuthi ukukhanya okungakanani okuboniswa yibhodi emehlweni omuntu, kubizwa ngokuthi ukukhanya okungakanani ibhodi elinakho, okungukuthi, ukukhanya kulingana nokukhanya okuphindaphindwe ngokukhanya, endaweni efanayo egumbini elifanayo, indwangu emhlophe kanye nengxenye yokukhanya. Ukukhanya kwemakethe emnyama kuyafana, kodwa ukukhanya kuhlukile.
5.Ukusebenza Okukhanyayo Komthombo Wokukhanya
Isilinganiso sokukhanya okuphelele okuphuma kumthombo wokukhanya kumandla kagesi (w) asetshenziswa umthombo wokukhanya sibizwa ngokuthi ukusebenza kahle kokukhanya komthombo wokukhanya, futhi iyunithi iyi-lumens/watt (Lm/W)
6.Izinga Lokushisa Lombala (i-CCT)
Uma umbala wokukhanya okhishwa ngumthombo wokukhanya useduze nombala okhishwa ngumzimba omnyama ekushiseni okuthile, izinga lokushisa lomzimba omnyama libizwa ngokuthi izinga lokushisa lombala (CCT) lomthombo wokukhanya, kanti iyunithi ingu-K. Imithombo yokukhanya enezinga lokushisa lombala elingaphansi kuka-3300K inombala obomvu futhi inikeza abantu umuzwa ofudumele. Uma izinga lokushisa lombala lidlula u-5300K, umbala uba luhlaza okwesibhakabhaka futhi unikeza abantu umuzwa opholile. Ngokuvamile, imithombo yokukhanya enezinga lokushisa lombala elingaphezu kuka-4000K isetshenziswa ezindaweni ezinezinga lokushisa eliphezulu. Ezindaweni eziphansi, sebenzisa imithombo yokukhanya engaphansi kuka-4000K.
7.Inkomba Yokunikeza Umbala (Ra)
Kokubili ukukhanya kwelanga kanye nezibani ezikhanyayo kukhanyisa i-spectrum eqhubekayo. Izinto zibonisa imibala yazo yangempela ngaphansi kokukhanya kwelanga okukhulu kanye nezibani ezikhanyayo, kodwa lapho izinto zikhanyiswa izibani zokukhipha igesi ezingapheli, umbala uzoba namazinga ahlukene okuHlanekezelwa, izinga lomthombo wokukhanya kumbala wangempela wento liba ukuboniswa kombala komthombo wokukhanya. Ukuze kulinganiswe ukuboniswa kombala komthombo wokukhanya, umqondo wenkomba yokuboniswa kombala wethulwa. Ngokusekelwe ekukhanyeni okujwayelekile, inkomba yokuboniswa kombala ichazwa njenge-100. Inkomba yokuboniswa kombala yeminye imithombo yokukhanya ingaphansi kwe-100. Inkomba yokuboniswa kombala ivezwa yi-Ra. Uma inani likhulu, kulapho ukuboniswa kombala komthombo wokukhanya kuba ngcono.
8.Isikhathi Esimaphakathi Sokuphila
Isikhathi sokuphila esimaphakathi sibhekisela enanini lamahora lapho ama-50% ezibani ezibangeni elilodwa ekhanya khona lapho onakele.
9.Isikhathi sokuphila komnotho
Impilo yezomnotho ibhekisela enanini lamahora lapho umkhiqizo womsebe ohlanganisiwe wehliswa ube yisilinganiso esithile, kucatshangelwa umonakalo webhalbhu kanye nokuncipha komkhiqizo womsebe. Isilinganiso singama-70% emithonjeni yokukhanya yangaphandle kanye nama-80% emithonjeni yokukhanya yangaphakathi.
10.Ukusebenza Kahle Okukhanyayo
Ukusebenza kahle komthombo wokukhanya kubhekisela esilinganisweni sokugeleza okukhanyayo okukhishwa umthombo wokukhanya kumandla kagesi u-P asetshenziswa umthombo wokukhanya.
11.Ukukhanya okukhazimulayo
Uma kunezinto ezikhanya kakhulu emkhakheni wokubuka, kuzoba nzima ukubona, okubizwa ngokuthi ukukhanya okukhazimulayo. Ukukhanya okukhazimulayo kuyisici esibalulekile esithinta ikhwalithi yemithombo yokukhanya.
Ingabe ucacile manje? Uma unemibuzo, ungangabazi ukuxhumana noLiper.
