Mayelana namalambu emoto, ngokuvamile sinaka inani lama-lumens namandla. Ngokuvamile kunenkolelo yokuthi ukuphakama "kwenani le-lumen", izibani zikhanya kakhulu! Kodwa ngezibani ze-LED, awukwazi ukumane ubheke inani le-lumen. Okubizwa ngokuthi i-lumen iyunithi ebonakalayo echaza ukugeleza okukhanyayo, okuchazwa yi-physics njengekhandlela (cd, candela, iyunithi yokukhanya okukhanyayo, okulingana nokukhanya okukhanyayo kwekhandlela elijwayelekile), nge-engeli eqinile (iyunithi). indilinga enendawo eyimitha eyi-1). Endimeni, i-engeli emelwe ikhoni eyindilinga ehambisana nomqhele oyindilinga wemitha-skwele elingu-1, ohambelana ne-engeli emaphakathi yesigaba esimaphakathi (cishe u-65°), ikhiqiza ukugeleza okukhanyayo okuphelele okukhishiwe.
Ukuze sibe nokuzwiseka okwengeziwe, sizosebenzisa ithoshi le-LED ukwenza isilingo esilula. Ithoshi liseduze kakhulu nokuphila futhi lingabonisa inkinga ngokuqondile.
Kusukela ezithombeni ezine ezingenhla, singabona ukuthi ithoshi elifanayo linomthombo wokukhanya ofanayo, kodwa i-reflector ivinjiwe, ngakho-ke kukhona umehluko omkhulu, obonisa ukuthi ukukhanya kwe-flashlight akuhlobene kuphela nokukhanya kwe-flashlight. umthombo wokukhanya ngokwawo, kodwa futhi awunakuhlukaniswa nesibonisi. Ubudlelwano. Ngakho-ke, ukukhanya kwezibani akukwazi ukuhlolwa kuphela ngama-lumens. Ezibani zangaphambili, kufanele sisebenzise "ukukhanya kokukhanya" okungokoqobo ukwahlulela,
Amandla okukhanya asho amandla okukhanya okubonakalayo atholwe endaweni yeyunithi ngayinye, okubizwa ngokuthi ukukhanya, futhi iyunithi iyi-Lux (Lux noma Lx). Igama elibonakalayo elisetshenziselwa ukukhombisa amandla okukhanya kanye nenani lokukhanya endaweni engaphezulu yento.
Indlela yokulinganisa yokukhanyisa nayo ilula futhi iluhlaza. Ngemuva kokulayisha, ingalinganiswa kuphela nge-illuminometer. Ama-lumens angafakazela kuphela idatha yelambu ngokwayo ngaphambi kokuba imoto ifakwe. Ukukhanya ngemva kwemoto kudinga ukugxiliswa futhi kumiswe isibonisi. Uma ukugxila kungalungile, uma ukukhanya kungenakunqanyulwa ngokugcwele, kungakhathaliseki ukuthi i-"lumen" ephakeme kangakanani ayikho iphuzu.

Amalambu emoto nawo adinga ukukhipha ukukhanya ngomthombo wokukhanya bese enqanyulwa yinkomishi ye-reflector. Umehluko wethoshi ukuthi indawo yokukhanya yemoto ayindilinga njengethoshi. Izidingo zezibani zemoto ziqinile futhi ziyinkimbinkimbi, ekuphepheni kokushayela futhi Ngokucabangela ukuphepha kwabahamba ngezinyawo, kuye kwasungulwa indinganiso ye-engeli kanye nobubanzi bokukhanya, futhi leli zinga libizwa ngokuthi "uhlobo olukhanyayo".
"Uhlobo olukhanyayo" (i-low beam) lwamalambu kufanele lube phansi kwesokunxele futhi lube phezulu kwesokudla, ngoba ohlangothini lwesobunxele lwezimoto zasekhaya indawo yomshayeli. Ukuze ugweme ukukhanya okukhazimulayo futhi uthuthukise ukuphepha kokushayela lapho izimoto ezimbili zihlangana zodwa phakathi nokushayela ebusuku. Indawo yokukhanya kwesokudla iphakeme. Kumshayeli wemoto eshayela ngesandla sobunxele, uhlangothi lwesokudla lwemoto aluboni kahle futhi ludinga indawo yokubona ebanzi. Zama ukukwazi ukukhanyisa i-pavement, ukuphambana kwemigwaqo nezinye izimo zomgwaqo ngendawo enkulu kwesokudla, uma kungenzeka. Thatha isinyathelo kusenesikhathi. (Uma kuyimoto eshayela kwesokudla, iphethini yokukhanya iphambene)
Izinzuzo zezibani ze-LED
1. Imikhiqizo yokukhanya kwe-LED ine-low-voltage eqalayo, futhi isici sokuphepha siphezulu uma kuqhathaniswa;
2. Imikhiqizo yokukhanya kwe-LED iqala ngokushesha, okuhambisana kakhulu nezidingo zezimoto zabantu;
3. Ukonga amandla nokuvikelwa kwemvelo, okunezinzuzo ezisobala zokuthuthukiswa kwezimoto zamandla amasha esikhathini esizayo;
4. Ngokuthuthukiswa okuqhubekayo nokuthuthukiswa kochungechunge lwemboni yobuhlalu belambu le-LED lamandla aphezulu, inzuzo engabizi kakhulu yezibani ze-LED izophinde yembulwe.
5. Ipulasitiki yomthombo wokukhanya we-LED inamandla uma iqhathaniswa, efaneleka kakhulu kumkhuba wokusetshenziswa komuntu siqu wesikhathi esizayo.
