Kutheni ufuna into efanelekileyo isibane sentloko kwinkampu, izibane zentloko ziphathwa kwaye zikhaphukhaphu, kwaye ziyimfuneko ekuhambeni ebusuku, izixhobo zokulungelelanisa kunye namanye amaxesha.
I-1, ikhanya ngakumbi: iphezulu i-lumens, ukukhanya ngakumbi!
Ngaphandle, amaxesha amaninzi "okukhanyayo" kubaluleke kakhulu. Umzekelo, intaba yomgca wasebusuku okanye uphonononge umqolomba, ukuqaqamba akwanelanga kunokukhubeka, ukuwa, okanye ukuphosa i-signpost ebalulekileyo; "Izibane" ziya kukwenza ube "yintlekele". Ukuba ufuna ukukhanya, ngoko kufuneka ubeke ingqalelo kwiparameter ye-lumens.
(1) Umlinganiselo wokukhanya ovela kwilumens
Ubomi, sihlala sithi ukukhanya "okukhanyayo okanye akunjalo", enyanisweni, kubhekiselele kwi-flux ekhanyayo. Iyunithi yokukhanya okukhanyayo yi-lumen, ebonisa umthamo okhanyayo womthombo wokukhanya. Ukuba ufuna ukuthenga ukukhanya okukhanyayo, kufuneka sinikele ingqalelo kwi-lumens yale parameter. Ukukhanya okuphezulu kukuvumela ukuba ubone ngokucacileyo indawo ephambi kwakho.
(2) Ukuba likhulu kwexabiso lelumen, kokukhona ukukhanya kuqaqamba.
Kubaizibane zangaphandle kwaye iithotshi, kukho ubudlelwane obuhle phakathi kwe-lumens kunye nokukhanya: ixabiso elikhulu le-lumen, ubukhulu be-flux ekhanyayo, amandla amakhulu okukhanya komthombo wokukhanya. Umzekelo, aIsibane se-lumen se-1000 liqaqambile kuno-a I-300 ye-lumen headlamp.
(3) Ukukhethwa kokuqaqamba
Ukuphakama kwexabiso lemveliso kuphezulu, xa kuthengwa kufuneka kudityaniswe nokusetyenziswa kwabo kwendawo. I-lumens eyi-100 ilingana nokukhanya kwamakhandlela asi-8, eyona misebenzi iphambili yokukhwela inkampu yangaphandle ukukhetha 100 ~ 200 lumens yeemveliso ngokwaneleyo; iimveliso zokukhanyisa ezingxamisekileyo ezincinci zihlala kwi-lumens engama-50 okanye kunjalo, kodwa zinokuhlangabezana neemfuno zokukhanya.
Ukuba uthatha inxaxheba kwimidlalo yangaphandle ineemfuno eziphezulu zokukhanyisa, unokuqwalasela i-200 ~ 500 yeemveliso ze-lumens. Ukuba kukho iimfuno eziphezulu, ezifana nokuhamba ngokukhawuleza (ubusuku bokuwela ilizwe), okanye imfuno yokukhanyisa indawo enkulu, unokuqwalasela i-500 ~ 1000 lumens yeemveliso.
Iimfuno zobungcali, ezifana nokukhangela kokuhlangula, unokuqwalasela ngaphezu1000 lumens isibane sentloko. Ukukhanya akuthethi ukuba kude, ngamanye amaxesha kufuneka ukhangele kwaye uqwalasele, ngokuqinisekileyo unethemba lokuba ukukhanya kukude, ngoko ufuna enye ipharamitha ekhankanywe ngezantsi.
