Qala ulandele i-libme ukuba ifunde ngakumbi malunga nokukhanya Candila & Lumen (CD & LM) Iyunithi yokukhanya ukukhanya yi-Candila, esekwe kubungakanani bekhandlela yekhandlela eliqhelekileyo, kodwa ngoku ichazwa njenge-1/60 yokukhanya ekhutshwe ngamaqondo omzimba amnyama kwiqondo eliqinileyo lePlatinam. Umthombo wokukhanya uyinto yonke imikhombandlela. Emitting 1 candela of light means emitting 12.3 lumens, that is, emitting 1 lumen per unit solid angle. I-lumen yiyunithi yokuhamba okukhanyayo. Ukukhanyisela (I-BOT) Isixa sokukhanya esisasazekileyo kumphezulu obambeleyo sibizwa ngokuba yikhanyino. Ivezwe kwi-lumens yecandelo ngalinye. I-lumen enye inyawo ngonyawo lwesikwere sisixa sezibane ebekiweyo ukusuka kumphezulu wesenzo kunye ne-piela enye. Ukukhanya kwelanga kwisibhakabhaka esicacileyo ngexesha lemini simalunga ne-1 000 ngamanyala ngonyawo ngalunye. Kwitafile yokutyela ekhanyayo, imalunga nama-20 lumens ngonyawo ngalunye. Iyunithi ehambelana ne-metric, eyi-1 lumen nganye yesikwere. I-1 lumen nganye nganye ilingane ne-10.76 Quo okanye kufutshane ne-10. E-United States, iinyawo ezihamba ngeenyawo zisetyenziswa endaweni yethu lusizi ngemitha nganye yesikwere, ngelixa i-UK isebenzisa le yokugqibela ukuba ifane. Isetyenziswe kumazwe aseYurophu. Ukucingisisa okunelungelo Xa ukukhanya kuwela kumphezulu, kubonakaliswa ngokweempawu zomphezulu. Le ndawo ibizwa ngokuba yimbonakalo yomphezulu. Ukucamngca komgangatho omhlophe kufutshane ne-100%, ngelixa inkanuko yendlela ye-asphalt i-10% kuphela. Ukukhanya komphezulu wento inxulumene nokukhanyisa kuyo. Umzekelo, ukuba umphezulu onomxholo we-100% ukhanyiselwe iinyawo ezili-10, ixabiso lefotopic leli-10 leenyawo. I-equation inokubhalwa njenge: L = Er - (1) Phakathi kwawo, l yi-PopilePpic Degree kwiimitha eziziimitha, kwaye i-lests ingeyonto inyawo. R inkanuko, ibonakaliswe njengenxalenye yenye. Sebenzisa iiyunithi zeMetrikhi, iyunithi ye-L ngu-L ngu-LIS Okokwalela (1 uwexuko ulingana ne-0.0001 ye-lamlert) kunye neyunithi ye-E. I-equation (1) isebenza kuphela kwindawo ebonakalayo egqibeleleyo kwaye ayisebenzi ukuba umphezulu une-sheen etshisayo okanye engabonakali esweni.
Zithini iimfuno zokukhanya kwivenkile yentengiso?
Amanqanaba oqhelekileyo okukhanya kwevenkile yevenkile ye-rocermarkes ukusuka kwi -750 ukuya kwi-1000 I-IT . Inqanaba lemibala enikezela ngevenkile ethengisa ivenkile inokuthi ubuncinci yi-RA ≥80 yekhanyini ngokubanzi kunye ne-ra ≥90 yezibane ezingenayo kunye neendawo ezintsha. Inqanaba lokukhanya kwimithombo yokukhanya akufuneki idlule ku-Ugr <19.
Njengoko kubonisiwe kumzobo ongezantsi, izibane zomgca we-Lithome ze-Lithor's Tracks zisetyenziswa kwivenkile enkulu yokufikelela kwi-450llux ngelixa udibana u-Ugr <13. Oku kusebenza kakuhle kakhulu kwindawo yokuthengisa.
