Kuyinto evamile kakhulu ukuthi izibani ze-LED ziba mnyama njengoba zisetshenziswa. Kunezizathu ezintathu ezingenza izibani ze-LED zifiphale:.
IDrayivu ilimele
Ama-chips e-LED ayadingeka ukuze asebenze ku-voltage ye-DC ephansi (ngaphansi kuka-20V), kodwa amandla ethu avamile ama-main angamandla kagesi aphezulu we-AC (220V AC). Ukuze uguqule amandla kagesi abe ugesi odingekayo kuma-chips e-LED, idivayisi ebizwa ngokuthi "i-LED constant current driving power supply" iyadingeka.
Ngokombono, inqobo nje uma imingcele yomshayeli ihambisana nebhodi le-LED, inganikwa amandla ngokuqhubekayo futhi isetshenziswe ngokujwayelekile. Isakhiwo sangaphakathi somshayeli siyinkimbinkimbi impela, futhi noma iyiphi idivayisi (efana ne-capacitor, i-rectifier, njll.) ukuthi ukungasebenzi kahle kungase kubangele ushintsho ku-voltage okukhiphayo, okungabangela ukuthi isibani sokukhanyisa sibe sifiphele.
Ukulimala komshayeli kuwuhlobo oluvame kakhulu lokungasebenzi kahle kwezibani ze-LED, okungase kuxazululwe ngazo ngokufaka umshayeli esikhundleni.
I-LED iphelile
I-LED ngokwayo yakhiwe ngenhlanganisela yobuhlalu obukhanyayo, futhi uma eyodwa noma ingxenye yabo ingakhanyi, nakanjani izokwenza isibani sonke sifiphale. Ubuhlalu besibani buvamise ukuxhunywa ngochungechunge bese ngokuhambisana - ngakho uma ubuhlalu obubodwa busha, bungabangela inqwaba yobuhlalu ukuthi ingakhanyi.
Kunamabala amnyama asobala ebusweni bobuhlalu besibani esishile. Ithole bese uxhuma ucingo emhlane wayo ukuze uyijikeleze kancane; Okunye, ukushintsha isibani esikhundleni esisha kungaxazulula inkinga.
Ngezinye izikhathi, i-LED eyodwa iyasha, kungase kube ukuqondana. Uma ivame ukushisa, khona-ke izinkinga zokushayela kufanele zicatshangelwe - okunye ukubonakaliswa kokwehluleka kwedrayivu ukushiswa kwama-chips e-LED.
Ukubola kokukhanya kwe-LED
Okubizwa ngokuthi ukubola kokukhanya kubhekisela ekukhanyeni okunciphayo komzimba okhanyayo, okubonakala kakhulu kumalambu e-incandescent kanye ne-fluorescent.
Izibani ze-LED nazo azikwazi ukugwema ukubola kokukhanya, kodwa izinga labo lokubola kokukhanya lihamba kancane, futhi ngokuvamile kunzima ukubona izinguquko ngeso lenyama. Kodwa ngeke kukhishwe ukuthi ama-LED ekhwalithi ephansi, noma amabhodi obuhlalu bekhwalithi ephansi, noma izici ezihlosiwe ezifana nokungashisi kahle ukushisa zingabangela izinga lokubola kokukhanya kwe-LED ukuthi lisheshe.
