Ngemuva kwamashumi eminyaka okuthuthukiswa kwezobuchwepheshe, ukusebenza kahle okukhanyayo kwe-LED kuye kwaba ngcono kakhulu. Ngenxa ye-monochromaticity enhle kanye ne-spectrum encane, ingakwazi ukukhipha ukukhanya okubonakalayo okunemibala ngaphandle kokuhlunga. Iphinde ibe nezinzuzo zokukhanya okuphezulu, ukusetshenziswa kwamandla okuphansi, impilo yesevisi ende, ukuqalisa okusheshayo, njll. ingalungiswa iminyaka eminingi, kunciphisa kakhulu izindleko zokulondoloza. Ngokudayiswa kokukhanya okuphezulu kwe-LED ngemibala ebomvu, ephuzi, eluhlaza kanye neminye, i-LED kancane kancane isithathele indawo isibani se-incandescent esivamile njengesilambu sethrafikhi.
Njengamanje, i-LED enamandla amakhulu ayisetshenziswa kuphela emikhiqizweni yenani eliphezulu lesesekeli njengokukhanya kwezimoto, izinto zokukhanyisa, i-LCD backlight, amalambu omgwaqo we-LED, kodwa futhi ingathola inzuzo enkulu. Kodwa-ke, ngokufika kokushintshwa kwamarobhothi ajwayelekile emfashini endala namalambu angavuthiwe amasignali e-LED eminyakeni edlule, amarobhothi e-LED anemibala emithathu egqamile athuthukiswe futhi asetshenziswa kabanzi. Eqinisweni, intengo yesethi ephelele yamarobhothi e-LED anemisebenzi ephelele kanye nekhwalithi ephezulu ibiza kakhulu. Kodwa-ke, ngenxa yendima ebalulekile yamarobhothi esiminyaminya sasemadolobheni, inani elikhulu lamarobhothi lidinga ukubuyekezwa njalo ngonyaka, okuholela emakethe enkulu uma kuqhathaniswa. Phela, inzuzo ephezulu ibuye ibe nomthelela ekuthuthukisweni kwezinkampani zokukhiqiza nezokuklama ze-LED, futhi zizokhiqiza ukugqugquzela okuhle kuyo yonke imboni ye-LED.
Imikhiqizo ye-LED esetshenziswa emkhakheni wezokuthutha ikakhulukazi ihlanganisa inkomba yesignali ebomvu, eluhlaza nokuphuzi, isibonisi sesikhathi sedijithali, inkomba yomcibisholo, njll. Umkhiqizo udinga ukukhanya kwe-ambient okunamandla kakhulu emini ukuze kukhanye, futhi ukukhanya kufanele kuncishiswe ebusuku. ukugwema ukucwazimula. Umthombo wokukhanya welambu le-LED lethrafikhi yomyalo wakhiwe ama-LED amaningi. Lapho uklama umthombo wokukhanya odingekayo, izindawo eziningi zokugxila kufanele zicatshangelwe, futhi kunezidingo ezithile zokufakwa kwe-LED. Uma ukufakwa kungahambisani, kuzothinta ukufana komphumela okhanyayo wendawo ekhanyayo. Ngakho-ke, indlela yokugwema lesi sici kufanele kucatshangelwe ekuklanyeni. Uma umklamo we-optical ulula kakhulu, ukusatshalaliswa kokukhanya kwesibani sesignali kuqinisekiswa ngokuyinhloko ngombono we-LED ngokwayo, Khona-ke izidingo zokusabalalisa ukukhanya nokufakwa kwe-LED ngokwayo ziqinile, ngaphandle kwalokho lesi simo sizoba sobala kakhulu.
Amarobhothi e-LED nawo ahlukile kwamanye amalambu esignali (njengamalambu emoto) ekusabalaliseni ukukhanya, nakuba futhi anezidingo zokusabalalisa ukukhanya kokukhanya. Izidingo zamalambu emoto kulayini wokunqamula ukukhanya ziqine kakhulu. Inqobo nje uma ukukhanya okwanele kwabelwa indawo ehambisanayo ekwakhiweni kwezibani zezimoto, ngaphandle kokucabangela lapho ukukhanya kukhishwa khona, umklami angaklama indawo yokusabalalisa ukukhanya kwelensi ezifundeni ezincane namabhulokhi amancane, kodwa isibani sesiginali yethrafikhi futhi. idinga ukucabangela ukufana komphumela wokukhanya wendawo yonke ekhipha ukukhanya. Kumelwe ihlangabezane nezimfuneko zokuthi lapho ubheka indawo ephuma ukukhanya yesiginali kunoma iyiphi indawo yokusebenza esetshenziswa isibani sesignali, iphethini yesiginali kufanele icace futhi umphumela wokubukwayo kufanele ufane. Nakuba isibani se-incandescent nesibani sesignali somthombo wokukhanya we-halogen tungsten sinokukhipha ukukhanya okuzinzile nokufana okufanayo, anokukhubazeka okufana nokusetshenziswa okuphezulu kwamandla, impilo yesevisi ephansi, ukukhiqiza isibonisi sesignali ye-phantom kalula, nama-chips ombala kulula ukufiphala. Uma singakwazi ukunciphisa ukwenzeka kokukhanya okufile kwe-LED futhi sinciphise ukuncishiswa kokukhanya, ukusetshenziswa kokukhanya okuphezulu nokusetshenziswa kwamandla okuphansi okuholele esibani sesiginali kuzoletha izinguquko eziguquguqukayo emikhiqizweni yesibani sesignali.
