Ngemva kwamashumi eminyaka yentuthuko yezobuchwepheshe, ukusebenza kahle okukhanyayo kwe-LED kuthuthukiswe kakhulu. Ngenxa ye-monochromaticity yayo enhle kanye ne-spectrum encane, ingakhipha ngqo ukukhanya okubonakalayo okunemibala ngaphandle kokuhlunga. Iphinde ibe nezinzuzo zokukhanya okuphezulu, ukusetshenziswa kwamandla aphansi, impilo yesevisi ende, ukuqala okusheshayo, njll. ingalungiswa iminyaka eminingi, kunciphisa kakhulu izindleko zokulungisa. Ngokuthengiswa kwe-LED ekhanyayo ephezulu ngemibala ebomvu, ephuzi, eluhlaza kanye neminye, i-LED iye yathatha indawo yesibani sendabuko se-incandescent njengesibani sesignali yethrafikhi.
Njengamanje, i-LED enamandla aphezulu ayisetshenziswa kuphela emikhiqizweni enenani eliphezulu lokwengeza njengokukhanyisa kwezimoto, izibani, isibani sangemuva se-LCD, izibani zasemgwaqweni ze-LED, kodwa futhi ingathola inzuzo enkulu. Kodwa-ke, ngokufika kokufakwa esikhundleni kwezibani zethrafikhi ezivamile zakudala kanye nezibani zesignali ze-LED ezingavuthiwe eminyakeni edlule, izibani zethrafikhi ezintsha ze-LED ezinemibala emithathu zikhuthazwe kakhulu futhi zasetshenziswa. Eqinisweni, intengo yesethi ephelele yezibani zethrafikhi ze-LED ezinemisebenzi ephelele kanye nekhwalithi ephezulu ibiza kakhulu. Kodwa-ke, ngenxa yendima ebalulekile yezibani zethrafikhi ezimotweni zasemadolobheni, inani elikhulu lezibani zethrafikhi kudingeka libuyekezwe njalo ngonyaka, okuholela emakethe enkulu kakhulu. Phela, inzuzo ephezulu nayo ikhuthaza ukuthuthukiswa kwezinkampani zokukhiqiza nokuklama ze-LED, futhi izophinde ikhiqize ukukhuthazwa okuhle embonini yonke ye-LED.
Imikhiqizo ye-LED esetshenziswa emkhakheni wezokuthutha ifaka phakathi isibonakaliso sesignali esibomvu, esiluhlaza kanye nesiphuzi, isibonisi sesikhathi sedijithali, isibonakaliso somcibisholo, njll. Umkhiqizo udinga ukukhanya okunamandla kakhulu emini ukuze kukhanye, futhi ukukhanya kufanele kuncishiswe ebusuku ukuze kugwenywe ukukhanya. Umthombo wokukhanya wesibani somyalo wesignali yethrafikhi ye-LED wakhiwe ngama-LED amaningi. Lapho kuklanywa umthombo wokukhanya odingekayo, kufanele kucatshangelwe amaphuzu amaningi okugxila, futhi kunezidingo ezithile zokufakwa kwe-LED. Uma ukufakwa kungavumelani, kuzothinta ukufana komphumela wokukhanya wobuso obukhanyayo. Ngakho-ke, indlela yokugwema lesi sici kufanele icatshangelwe ekwakhiweni. Uma umklamo wokukhanya ulula kakhulu, ukusatshalaliswa kokukhanya kwesibani sesignali kuqinisekiswa kakhulu ngombono we-LED uqobo, khona-ke izidingo zokusatshalaliswa kokukhanya nokufakwa kwe-LED uqobo ziqinile, ngaphandle kwalokho lesi simo sizoba sobala kakhulu.
Izibani zethrafikhi ze-LED nazo zihlukile kwezinye izibani zesignali (njengezibani zemoto) ekusatshalalisweni kokukhanya, yize nazo zinezidingo zokusatshalaliswa kokukhanya okunamandla. Izidingo zezibani zemoto emgqeni wokusika ukukhanya ziqinile kakhulu. Uma nje ukukhanya okwanele kunikezwe indawo ehambisanayo ekwakhiweni kwezibani zemoto, ngaphandle kokubheka ukuthi ukukhanya kukhishwa kuphi, umklami angaklama indawo yokusatshalaliswa kokukhanya kwelensi ezifundeni ezincane nasemabhulokini amancane, kodwa isibani sesignali yethrafikhi sidinga futhi ukunaka ukufana komphumela wokukhanya wobuso bonke obukhipha ukukhanya. Kumelwe kuhlangabezane nezidingo zokuthi lapho kubonwa ubuso obukhipha ukukhanya besignali kunoma iyiphi indawo yokusebenza esetshenziswa isibani sesignali, iphethini yesignali kumele icace futhi umphumela obonakalayo kumele ufane. Nakuba isibani se-incandescent kanye nesibani se-halogen tungsten esikhanyayo sikhipha ukukhanya okuzinzile nokulinganayo, sineziphambeko ezifana nokusetshenziswa kwamandla aphezulu, impilo ephansi yesevisi, kulula ukukhiqiza isibonisi sesignali se-phantom, kanye nama-color chips kulula ukuwafiphaza. Uma singanciphisa ukwenzeka kokukhanya okungabonakali kwe-LED futhi sinciphise ukuncishiswa kokukhanya, ukusetshenziswa kokukhanya okuphezulu kanye nokusetshenziswa kwamandla aphansi kwe-LED esibanini sesignali nakanjani kuzoletha izinguquko ezinkulu emikhiqizweni yesibani sesignali.
