Emva kwamashumi eminyaka yophuhliso lwetekhnoloji, ukusebenza okukhanyayo kwe-LED kuye kwaphuculwa kakhulu.Ngenxa ye-monochromaticity entle kunye ne-spectrum emxinwa, inokukhupha ngokuthe ngqo ukukhanya okubonakalayo okunemibala ngaphandle kokucoca.Kananjalo ineenzuzo zokukhanya okuphezulu, ukusetyenziswa kwamandla aphantsi, ubomi benkonzo ende, ukuqalisa ngokukhawuleza, njl njl. inokulungiswa iminyaka emininzi, ukunciphisa kakhulu iindleko zokugcina.Ngokurhweba ngokuqaqamba okuphezulu kwe-LED ebomvu, emthubi, eluhlaza kunye neminye imibala, i-LED ngokuthe ngcembe ithathe indawo yesibane se-incandescent yesibane njengesibane sendlela.
Okwangoku, i-LED enamandla amakhulu ayisetyenziswanga kuphela kwiimveliso zexabiso eliphezulu ezifana nokukhanya kweemoto, izibane zokukhanyisa, ukukhanya kwe-LCD, izibane zesitrato ze-LED, kodwa zinokufumana inzuzo eninzi.Nangona kunjalo, ngokufika kokutshintshwa kwezibane zendlela eziqhelekileyo eziqhelekileyo kunye nezibane ze-LED ezingavuthiweyo kwiminyaka edlulileyo, izibane ze-LED ezinemibala eqaqambileyo ezintathu ziye zakhuthazwa ngokubanzi kwaye zasetyenziswa.Enyanisweni, ixabiso leseti epheleleyo yezibane ze-LED ezinemisebenzi epheleleyo kunye nomgangatho ophezulu ubiza kakhulu.Nangona kunjalo, ngenxa yendima ebalulekileyo yezibane zendlela kwiitrafikhi zasezidolophini, inani elikhulu lezibane zendlela kufuneka zihlaziywe minyaka yonke, nto leyo ekhokelela kwimarike enkulu.Emva kwayo yonke loo nto, iingeniso eziphezulu zikwaluncedo kuphuhliso lwemveliso ye-LED kunye neenkampani zoyilo, kwaye ziya kuvelisa uvuselelo oluhle kulo lonke ishishini le-LED.
Iimveliso ze-LED ezisetyenziswa kwintsimi yezothutho zibandakanya umqondiso obomvu, oluhlaza kunye notyheli, umboniso wexesha ledijithali, isalathisi sotolo, njl. njl. ukuphepha ukukhazimla.Umthombo wokukhanya wesibane somyalelo we-LED wetrafikhi yomyalelo wenziwa ngee-LED ezininzi.Xa uyila umthombo wokukhanya ofunekayo, iindawo ezininzi zokugxila kufuneka ziqwalaselwe, kwaye kukho iimfuno ezithile zokufakelwa kwe-LED.Ukuba ukufakela akuhambelani, kuya kuchaphazela ukufana kwesiphumo esikhanyayo sokukhanya okukhanyayo.Ngoko ke, indlela yokuphepha esi siphene kufuneka ithathelwe ingqalelo kuyilo.Ukuba idizayini ye-optical ilula kakhulu, ukuhanjiswa kokukhanya kwesibane somqondiso kuqinisekiswa ngokukodwa ngumbono we-LED ngokwayo, Ke iimfuno zokusabalalisa ukukhanya kunye nokufakwa kwe-LED ngokwayo zingqongqo, ngaphandle koko le nto iya kuba yinto ecacileyo kakhulu.
Izibane ze-LED zikwahluke kwezinye izibane zesignali (ezifana nezibane zemoto) ekuhanjisweni kokukhanya, nangona nazo zineemfuno zokusabalalisa ukukhanya.Iimfuno zezibane zemoto kumgca wokusikwa kokukhanya zingqongqo.Logama nje ukukhanya okwaneleyo kwabelwe indawo ehambelanayo kuyilo lwezibane zemoto, ngaphandle kokuqwalasela apho kukhutshwa khona ukukhanya, umyili unokuyila indawo yokuhambisa ukukhanya kwelensi kwimimandla engaphantsi kunye neebhloko, kodwa isibane somqondiso wetrafikhi kwakhona. idinga ukuthathela ingqalelo ukufana kwesiphumo sokukhanya kwendawo yonke ekhupha ukukhanya.Kufuneka ihlangabezane neemfuno zokuthi xa uqwalasela ukukhanya okukhupha ukukhanya komqondiso kuyo nayiphi na indawo yokusebenza esetyenziswa sisibane somqondiso, ipateni yomqondiso kufuneka icace kwaye umphumo obonakalayo kufuneka ufanane.Nangona isibane se-incandescent kunye ne-halogen tungsten isibane somthombo wokukhanya kwesibane sokukhanya okuzinzile kunye nokukhanya okufanayo, baneziphene ezifana nokusetyenziswa kwamandla aphezulu, ubomi benkonzo ephantsi, ukuvelisa umboniso we-phantom lula, kunye neetshiphusi zemibala kulula ukucima.Ukuba sinokunciphisa ukukhanya okufileyo kwe-LED kunye nokunciphisa ukukhanya kokukhanya, ukusetyenziswa kokukhanya okuphezulu kunye nokusetyenziswa kwamandla aphantsi okukhokelela kwisibane somqondiso ngokuqinisekileyo kuya kuzisa utshintsho oluguqukayo kwiimveliso zesibane somqondiso.
