1.I-Luminous Flux (F)
Isimbuku samandla akhutshwa ngumthombo wokukhanya kwaye afunyenwe ngamehlo omntu yi-flux ekhanyayo (iyunithi: lm(lumen)). Ngokubanzi, amandla aphezulu ohlobo olufanayo lwesibane, lukhulu ngakumbi umbane okhanyayo. Umzekelo, ukukhanya okukhanyayo kwesibane se-incandescent esiqhelekileyo se-40 yi-350-470Lm, ngelixa ukukhanya okukhanyayo kwe-40W eqhelekileyo yesibane esiqhelekileyo se-tube fluorescent malunga ne-28001m, engama-6 ~ 8 amaxesha wesibane se-incandescent.
2.Ukuqina okuLuminous(I)
I-flux ekhanyayo ekhutshwa ngumthombo wokukhanya kwiyunithi eqinileyo ye-engile kwicala elinikiweyo ibizwa ngokuba bubushushu obukhanyayo bomthombo wokukhanya ukuya kwelo cala, kwaye ngokungathanga ngqo ibizwa ngokuba yi-luminous intensity (iyunithi yi-cd (candela)), 1cd=1m/1s.
3.Illuminance(E)
Ukukhanya okukhanyayo okufunyenwe kwiyunithi nganye yendawo ekhanyisiweyo kubizwa ngokuba yi-illuminance (iyunithi yi-1x (i-lux), oko kukuthi, 11x=1lm/m². Ukukhanya komhlaba emini kunye nokukhanya okunamandla ehlotyeni malunga ne-5000lx, ukukhanya komhlaba kwimini enelanga ebusika0 kumhlaba ocacileyo 1x ukukhanya kwenyanga kunye ne-20 ebusuku malunga ne-0.2lX.
4.Ukukhanya (L)
Ukukhanya komthombo wokukhanya kwicala elithile, iyunithi yi-nt (ii-nits), yi-flux ekhanyayo ekhutshwa yiyunithi yendawo eqikelelweyo kunye neyunithi ye-engile eqinileyo yomthombo wokukhanya kwelo cala. Ukuba yonke into ithathwa njengomthombo wokukhanya, ke ukukhanya kuchaza ukuqaqamba komthombo wokukhanya, kwaye ukukhanya kuphatha nje yonke into njengento ekhanyisiweyo. Sebenzisa ibhodi yeplanga ukubonisa. Xa umqadi othile wokukhanya ubetha ibhodi yokhuni, kubizwa ngokuba kungakanani ukukhanya kwebhodi, kwaye ukukhanya okungakanani kubonakaliswa yibhodi kwiliso lomntu, kubizwa ngokuba bubuninzi bokukhanya kwebhodi, oko kukuthi, ukukhanya kuyalingana nokukhanya okuphindaphindwe yi-reflection, kwindawo efanayo kwigumbi elinye, iqhekeza lelaphu elimhlophe kunye nokukhanya okukhanyayo okufanayo, i-illumina ye-lightness efanayo. ezahlukeneyo.
5.UkuSebenza okuLuminous koMthombo wokuKhanya
Umlinganiselo wokukhanya okukhanyayo okuphuma kumthombo wokukhanya kumandla ombane (w) asetyenziswe ngumthombo wokukhanya kubizwa ngokuba bubuchule obuLuminous bomthombo wokukhanya, kwaye iyunithi yilumens/watt (Lm/W)
6.Ubushushu boMbala(CCT)
Xa umbala wokukhanya okhutshwe ngumthombo wokukhanya usondele kumbala okhutshwe ngumzimba omnyama kwiqondo elithile lobushushu, ubushushu bomzimba omnyama bubizwa ngokuba yiqondo lokushisa lombala (CCT) lomthombo wokukhanya, kwaye iyunithi yi-K. Imithombo yokukhanya kunye nobushushu bombala ongaphantsi kwe-3300K inombala obomvu kwaye inika abantu imvakalelo efudumeleyo. Xa ubushushu bombala budlula i-5300K, umbala uba bluish kwaye unika abantu imvakalelo epholileyo. Ngokuqhelekileyo, imithombo yokukhanya enobushushu bombala obungaphezulu kwe-4000K isetyenziswa kwiindawo ezinobushushu obuphezulu. Kwiindawo ezisezantsi, sebenzisa imithombo yokukhanya engaphantsi kwe-4000K.
7.Isalathiso sokuBonelela ngoMbala(Ra)
Zombini ukukhanya kwelanga kunye nezibane ze-incandescent zikhupha i-spectrum eqhubekayo. Izinto zibonisa imibala yazo yokwenyani phantsi kokukhanya kwelanga okukhulu kunye nezibane ze-incandescent, kodwa xa izinto zikhanyiswa zizibane zokukhutshwa kwegesi ye-spectrum engapheliyo, umbala uya kuba needigri ezahlukeneyo zokuPhatha, idigri yomthombo wokukhanya kumbala wokwenyani wento iba ngumbala wokunikezelwa komthombo wokukhanya. Ukulinganisa unikezelo lombala lomthombo wokukhanya, ingqikelelo yesalathiso sombala iyaziswa. Ngokusekelwe kukukhanya okusemgangathweni, isalathisi sombala sichazwa njenge-100. Isalathiso sombala weminye imithombo yokukhanya singaphantsi kwe-100. Isalathisi sombala sichazwa nguRa. Ixabiso elikhulu, kokukhona unikezelo lombala lomthombo wokukhanya.
8.I-Avareji yoBomi
Umndilili wobomi ubhekisa kwinani leeyure ezithi i-50% yezibane ezikwibhetshi yezibane zikhanyise xa zonakele.
9.Ubomi bezoqoqosho
Ubomi bezoqoqosho bubhekiselele kwinani leeyure xa ukukhutshwa kwe-beam edibeneyo kuncitshiswa kumlinganiselo othile, kuthathelwa ingqalelo umonakalo webhalbhu kunye nokuthotywa kwe-beam output. Umlinganiselo yi-70% yemithombo yokukhanya yangaphandle kunye ne-80% yemithombo yokukhanya yangaphakathi.
10.Ubuchule obuqaqambileyo
Ukusebenza okukhanyayo komthombo wokukhanya kubhekiselele kumlinganiselo wokukhanya okukhanyayo okukhutshwa ngumthombo wokukhanya kumandla ombane we-P asetyenziswe ngumthombo wokukhanya.
11.Dazzle ukukhanya
Xa kukho izinto ezigqame ngokugqithisileyo kwibala lokujonga, iya kuba ingakhululeki ngokubonakalayo, ebizwa ngokuba yi-dazzle light. ukukhanya kwedazzle yinto ebalulekileyo echaphazela umgangatho wemithombo yokukhanya.
Ngaba ucacile ngoku? Ukuba unayo nayiphi na imibuzo, ungathandabuzi ukuqhagamshelana noLiper.
