Izibonisi ze-LED ziguqule indlela esidlulisela ngayo ulwazi, kokubili kuzilungiselelo zasendlini nezangaphandle. Izinhlobo ezimbili ezijwayelekile zobuchwepheshe be-LED zibusa emakethe: I-SMD (Idivayisi Ekhwezwe Ekuphakameni) I-LED kanye ne-DIP (I-Dual In-line Package) LED. Ngayinye inezici ezihlukile, futhi ukwazi ukuhlukana kwazo kubalulekile ukuze wenze ukukhetha okufanele kuye ngohlelo lwakho lokusebenza. Ake sihlukanise lezi zinhlobo ezimbili zezibonisi ze-LED futhi sihlole ukuthi zihluke kanjani ngokuya ngesakhiwo, ukusebenza, kanye nokusetshenziswa.
1. Isakhiwo se-LED
Umehluko obalulekile phakathi kwe-SMD ne-DIP LEDs usesimeni sawo somzimba:
Isibonisi se-SMD LED: Esibonisini se-SMD, ama-chips e-LED afakwa ngqo phezu kwebhodi lesekethe eliphrintiwe (PCB). I-SMD LED eyodwa ngokuvamile iqukethe ama-diode abomvu, aluhlaza, naluhlaza okwesibhakabhaka kuphakheji eyodwa, okwenza iphikseli.
I-DIP LED Display: Ama-LED e-DIP aqukethe ama-diode ahlukene abomvu, aluhlaza, naluhlaza okwesibhakabhaka ambozwe ngegobolondo leresin eqinile. Lawa ma-LED afakwa ngezimbobo ku-PCB, futhi i-diode ngayinye yenza ingxenye yephikseli enkulu.
2. Idizayini yePixel nokuminyana
Ukuhlelwa kwama-LED kuthinta ukuminyana kwephikseli nokucaca kwesithombe kwazo zombili izinhlobo:
I-SMD: Ngenxa yokuthi womathathu ama-diode (RGB) aqukethwe ephaketheni elilodwa elincane, ama-SMD LED avumela ukuminyana kwephikseli okukhulu. Lokhu kuzenza zilungele izibonisi ezinokulungiswa okuphezulu lapho kudingeka khona imininingwane emihle nezithombe ezibukhali.
I-DIP: Umbala ngamunye we-diode ubekwe ngokuhlukile, okhawulela ukuminyana kwephikseli, ikakhulukazi ekubonisweni kwephimbo elincane. Ngenxa yalokho, ama-LED e-DIP ngokuvamile asetshenziswa ezinhlelweni lapho ukulungiswa okuphezulu kungeyona into ebaluleke kakhulu, njengezikrini ezinkulu zangaphandle.
3. Ukukhanya
Ukukhanya kungenye into ebalulekile lapho ukhetha phakathi kwezibonisi ze-SMD ne-DIP ze-LED:
I-SMD: Ama-LED ama-SMD anikeza ukukhanya okusesilinganisweni, okuvamise ukufaneleka endaweni yasendlini noma engaphandle. Inzuzo yabo eyinhloko ukuxutshwa kombala okuphakeme kanye nekhwalithi yesithombe, kunokukhanya okwedlulele.
I-DIP: Ama-LED e-DIP aziwa ngokugqama kwawo okukhulu, okuwenza alungele ukusetshenziswa kwangaphandle. Bangakwazi ukugcina ukubonakala okucacile elangeni eliqondile, okungenye yezinzuzo zabo ezibaluleke kakhulu kunobuchwepheshe be-SMD.
4. I-engeli yokubuka
I-engeli yokubuka isho ukuthi ungabuka kude kangakanani maphakathi nesibonisi ngaphandle kokulahlekelwa ikhwalithi yesithombe:
I-SMD: Ama-LED ama-SMD anikezela nge-engeli yokubuka ebanzi, ngokuvamile efika ku-160 degrees ngokuvundlile nangokuqondile. Lokhu kuzenza zibe yinketho edumile yezibonisi zasendlini, lapho izethameli zibuka izikrini ngama-engeli amaningi.
I-DIP: Ama-LED e-DIP avame ukuba ne-engeli yokubuka encane, ngokuvamile azungeze ama-degree angu-100 kuya kwangu-110. Nakuba lokhu kwanele kumasethingi angaphandle lapho izibukeli ngokuvamile zikude khona, akulungele kangako ukubuka eduze noma ngaphandle kwe-engeli.
5. Ukuqina Nokumelana Nesimo Sezulu
Ukuqina kubalulekile, ikakhulukazi kuzibonisi zangaphandle ezibhekene nezimo zezulu eziyinselele:
I-SMD: Nakuba ama-SMD LED elungele ukusetshenziswa okuningi kwangaphandle, aqinile kakhulu kunama-DIP LEDs esimweni sezulu esibi kakhulu. Idizayini yabo ebekwe phezulu ibenza babe sengozini kakhudlwana yokulimala ngenxa yomswakama, ukushisa, noma imithelela.
I-DIP: Ama-LED e-DIP ngokuvamile ahlala isikhathi eside futhi anikeza ukumelana nesimo sezulu esingcono. Isikhwama sabo se-resin esivikelayo sibasiza ukuthi bamelane nemvula, uthuli, namazinga okushisa aphezulu, okubenza babe yinketho yokukhethwa kukho kokufakwa okukhulu kwangaphandle njengamabhodi okukhangisa.
6. Ukuphumelela Kwamandla
Ukusetshenziswa kwamandla kungase kube ukukhathazeka ekufakweni kwesikhathi eside noma okukhulu:
I-SMD: Izibonisi ze-SMD zingonga kakhulu amandla kunezibonisi ze-DIP ngenxa yedizayini yazo ethuthukisiwe nosayizi ohlangene. Zidinga amandla amancane ukuze zikhiqize imibala egqamile nezithombe ezinemininingwane, okuzenza zibe ukukhetha okuhle kumaphrojekthi akhathalela amandla.
I-DIP: Izibonisi ze-DIP zisebenzisa amandla engeziwe ukuze zifinyelele amazinga azo okukhanya aphezulu. Lesi sidingo esinyukile samandla singaholela ezindlekweni zokusebenza eziphezulu, ikakhulukazi ukufakwa kwangaphandle okusebenza ngokuqhubekayo.
7. Izindleko
Isabelomali sidlala indima ebalulekile ekunqumeni phakathi kwezibonisi ze-SMD ne-DIP ze-LED:
I-SMD: Ngokujwayelekile, izibonisi ze-SMD zibiza kakhulu ngenxa yamakhono azo anokulungiswa okuphezulu kanye nenqubo yokukhiqiza eyinkimbinkimbi. Kodwa-ke, ukusebenza kwazo ngokuya ngokunemba kombala kanye nokuminyana kwe-pixel kuthethelela izindleko zezinhlelo zokusebenza eziningi.
I-DIP: Izibonisi ze-DIP ngokuvamile zithengeka kakhulu, ikakhulukazi ukufakwa kwangaphandle okukhulu, okunokulungiswa okuphansi. Izindleko eziphansi zibenza babe ukukhetha okudumile kumaphrojekthi adinga ukuqina kodwa hhayi imininingwane emihle.
8. Izicelo Ezivamile
Uhlobo lwesibonisi se-LED olukhethayo luzoncika kakhulu kuhlelo oluhlosiwe:
I-SMD: Ama-LED ama-SMD asetshenziswa kakhulu emibukisweni yasendlini, okuhlanganisa amagumbi enkomfa, izimpawu zokudayisa, imibukiso yombukiso wezohwebo, nezitudiyo zikamabonakude. Ziphinde zitholakale ekufakweni okuncane kwangaphandle lapho ukulungiswa okuphezulu kubalulekile, njengezikrini zokukhangisa eziseduze.
I-DIP: Ama-LED e-DIP abusa ukufakwa okukhulu kwangaphandle, okufana namabhodi ezikhangiso, izikrini zenkundla, nezibonisi zemicimbi yangaphandle. Idizayini yazo eqinile nokukhanya okuphezulu kuzenza zilungele izindawo lapho ukuqina okudlulele kanye nokubonakala kokukhanya kwelanga kuyadingeka.
Isiphetho: Ukukhetha Phakathi Kwezibonisi ze-SMD ne-DIP ze-LED
Uma ukhetha phakathi kwesibonisi se-SMD ne-DIP ye-LED, kubalulekile ukucabangela izidingo ezithile zephrojekthi yakho. Uma udinga ukulungiswa okuphezulu, ama-engeli okubuka abanzi, kanye nekhwalithi yesithombe engcono, ikakhulukazi kuzilungiselelo zasendlini, izibonisi ze-SMD LED ziyindlela okufanele uhambe ngayo. Ngakolunye uhlangothi, ekufakweni kwangaphandle kwesilinganiso esikhulu lapho ukukhanya, ukuqina, nokusebenza kahle kwezindleko kubalulekile, izibonisi ze-DIP ze-LED ngokuvamile ziyinketho engcono.
