Ngokuphathelele izibane zemoto, ngokuqhelekileyo sinikela ingqalelo kwinani le-lumens kunye namandla. Ngokuqhelekileyo kukholelwa ukuba phezulu "ixabiso le-lumen", izibane ezikhanyayo! Kodwa kwizibane ze-LED, awukwazi ukubhekisa kwixabiso le-lumen. Into ebizwa ngokuba yi-lumen yiyunithi yomzimba echaza ukukhanya okukhanyayo, okuchazwa yi-physics njengekhandlela (i-cd, i-candela, iyunithi yokukhanya okukhanyayo, ilingana nokukhanya okukhanyayo kwekhandlela eliqhelekileyo), kwi-angle eqinileyo (iyunithi isangqa kunye ne-radius ye-1 yeemitha). Kwi-sphere, i-angle emelwe yi-cone ye-spherical ehambelana nesithsaba se-spherical se-spherical meter ye-square, ehambelana ne-angle ephakathi yecandelo eliphakathi (malunga ne-65 °), ivelisa i-flux ekhanyayo epheleleyo.
Ukuze sibe nokuqondakala ngakumbi, siya kusebenzisa isibane se-LED ukwenza umfuniselo olula. Isibane sikufutshane ebomini kwaye sinokubonisa ngokuthe ngqo ingxaki.
Ukususela kule mifanekiso ingentla, sinokubona ukuba isibane esifanayo sinomthombo wokukhanya ofanayo, kodwa i-reflector ivaliwe, ngoko kukho umahluko omkhulu, obonisa ukuba ukukhanya kwesibane akuhambelani kuphela nokukhanya kokukhanya. umthombo wokukhanya ngokwawo, kodwa nawo awunakwahlulwa kwisibonisi. Ubudlelwane. Ngoko ke, ukukhanya kwezibane akukwazi ukuvavanywa kuphela nge-lumens. Kwizibane zangaphambili, kufuneka sisebenzise "ukukhanya kokukhanya" okubonakalayo ukugweba,
Ukukhanya kokukhanya kubhekisa kumandla okukhanya okubonakalayo afunyenwe kwindawo nganye yeyunithi, ekubhekiswa kuyo njengokukhanya, kwaye iyunithi yiLux (Lux okanye Lx). Igama elibonakalayo elisetyenziselwa ukubonisa ubunzulu bokukhanya kunye nomthamo wokukhanya kumphezulu wento.
Indlela yokulinganisa yokukhanyisa nayo ilula kwaye ikrwada. Emva kokulayisha, inokulinganiswa kuphela nge-illuminometer. I-lumens inokungqina kuphela idatha ye-headlight ngokwayo phambi kokuba imoto ifakwe. Ukukhanya emva kwemoto kufuneka kugxininiswe kwaye kuhlanjululwe ngumbonisi. Ukuba ugxininiso alulungile, ukuba ukukhanya akukwazi ukuchaswa ngokupheleleyo, kungakhathaliseki ukuba "lumen" iphakamileyo kangakanani.

Izibane zemoto nazo kufuneka zikhuphe ukukhanya ngomthombo wokukhanya kwaye emva koko zihlanjululwe yikomityi yesibonisi. Umahluko ukusuka kwisibane kukuba indawo yokukhanya yokukhanya kwemoto ayikho setyhula njengetotshi. Iimfuno zezibane zemoto zingqongqo kwaye zinzima, ukhuseleko lokuqhuba kwaye Ukuqwalasela ukhuseleko lwabahamba ngeenyawo, umgangatho umiselwe i-angle kunye noluhlu lokukhanya, kwaye lo mgangatho ubizwa ngokuba "uhlobo olukhanyayo".
"Uhlobo olukhanyayo" (i-beam ephantsi) yezibane kufuneka zibe phantsi ngakwesobunxele kwaye ziphakame ngakwesokudla, kuba icala lasekhohlo leemoto zasekhaya yindawo yomqhubi. Ukuze ugweme izibane ezikhanyayo kunye nokuphucula ukhuseleko lokuqhuba xa iimoto zombini zidibana ngexesha lokuqhuba ebusuku. Indawo yokukhanya ngasekunene iphezulu. Kumqhubi wemoto yesandla sasekhohlo, icala lasekunene lesithuthi linomgca ombi wokubona kwaye lifuna indawo ebanzi yokubona. Zama ukukwazi ukukhanyisa i-pavement, i-intersection kunye nezinye iimeko zendlela kunye nommandla omkhulu ngasekunene, ukuba kunokwenzeka. Thatha inyathelo kwangethuba. (Ukuba yimoto eqhuba ngasekunene, ipateni yokukhanya ichasene)
Izinto eziluncedo kwizibane ze-LED
1. Iimveliso zokukhanya ze-LED ziqala umbane ophantsi, kwaye ukhuseleko luphezulu;
2. Iimveliso zokukhanya ze-LED ziqala ngokukhawuleza, ezihambelana ngakumbi neemfuno zezithuthi zabantu;
3. Ukugcinwa kwamandla kunye nokukhuselwa kokusingqongileyo, kunye neenzuzo ezicacileyo zokuphuhliswa kwezithuthi zamandla amatsha kwixesha elizayo;
4. Ngokuphuculwa okuqhubekayo kunye nokuphuculwa komgangatho ophezulu wamandla we-LED yesibane se-bead chain chain, inzuzo eneendleko ezisebenzayo zezibane ze-LED ziya kutyhilwa ngakumbi.
5. Iplastiki yomthombo wokukhanya we-LED yomelele, ifaneleke kakhulu kwixesha elizayo lokusetyenziswa komntu.
