Izibonisi ze-LED zikhona yonke indawo namuhla. Zinemibala futhi zigqamile, zengeza umbala omningi ezimpilweni zethu. Kodwa wake wazibuza ukuthi lezi zibonisi ze-LED zenziwe ngani? Namuhla, ake sikhulume ngezingxenye ezibalulekile zezibonisi ze-LED - ubuhlalu bezibani.
Enye yezingxenye eziyinhloko zokuboniswa kwe-LED ubuhlalu bezibani, okungama-cubes noma ama-cuboid amaningi futhi anemininingwane ehlukahlukene, njengokuthi 3535, 3528, 2835, 2727 (2525), 2121, 1921, 1515, 1010, njll. ilayishwe kubakaki bensimbi, egcwele ingcina futhi yomiswe. Indawo yabo ekhanyayo ivamise ukuba nokukhanya okungaphambili okukodwa, futhi izikhonkwane zesibani zingathengiswa ngokuqondile ebhodini lesifunda le-PCB elinendawo yokunamathisela.
Ubuhlalu besibani se-LED bunokucaciswa okuhlukahlukene kanye namamodeli ukuzivumelanisa nezimo zohlelo lokusebenza ezahlukahlukene. Emkhakheni wama-LED ama-SMD angaphakathi, ukucaciswa kobuhlalu besibani okuvamile kufaka 0505, 1010, 1515, 2121, 3528, njll. Kuzinhlelo zokusebenza zangaphandle, amamodeli avamile ahlanganisa 1921, 2525, 2727, 3535, 5050, njll. Lezi zinombolo zokukhanya ze-LED zimelela usayizi we-LED wokukhanya. Isibonelo, u-0505 usho ukuthi ubude nobubanzi bengxenye ye-LED kokubili kungu-0.5mm.
Incazelo enemininingwane yokucaciswa kobuhlalu besibani
Usayizi wemethrikhi wobuhlalu belambu obungu-0505 ngu-0.5mm×0.5mm, futhi isifinyezo semboni singu-0505;
Usayizi wemethrikhi wobuhlalu besibani obuyi-1010 ngu-1.0mm×1.0mm, futhi isifinyezo semboni singu-1010;
Usayizi wemethrikhi wobuhlalu besibani obungu-2121 ngu-2.1mm×2.1mm, futhi isifinyezo semboni singu-2121;
Usayizi wemethrikhi wobuhlalu besibani obungu-3528 ngu-3.5mm×2.8mm, futhi isifinyezo semboni singu-3528;
Usayizi wemethrikhi wobuhlalu besibani obungu-5050 ngu-5.0mm×5.0mm, futhi isifinyezo semboni singu-5050.
Baningi abakhiqizi bobuhlalu belambu lokubonisa i-LED abaziwayo emhlabeni,
Ubuhlalu bezibani ze-LED bupakishwe ngezindlela ezihlukahlukene, kufaka phakathi i-plug-in eqondile, i-SMD, amandla aphezulu kanye nobuhlalu besibani se-COB LED. Ngasikhathi sinye, ubuhlalu besibani se-LED bunemibala, kufaka phakathi obomvu, ophuzi-oluhlaza okotshani, ophuzi, osawolintshi, oluhlaza okwesibhakabhaka, onsomi, opinki nomhlophe.
Lapho sihlonza izigxobo ezinhle nezingezinhle zobuhlalu bezibani ze-LED, singazihlukanisa ngokumaka nokwakheka. Ngokuvamile, isigxobo esihle sizomakwa njengechashazi elincane noma unxantathu futhi sizophumela ngaphandle; kuyilapho isigxobo esinegethivu singenazo izimpawu futhi sisifishane kancane kunephozithivu. Uma izigxobo ezinhle nezingezinhle zinganqunywa, singasebenzisa futhi i-multimeter ukuhlola.
Ukukhetha uhlobo olufanele lobuhlalu lwesibani se-LED kubalulekile ekuthuthukiseni ukusebenza nempilo yemikhiqizo ye-LED. Lapho sikhetha umkhiqizo, sidinga ukucabangela izici eziningi ukuze siqinisekise ukuthi uhlobo olukhethiwe luhlangabezana nezidingo zethu.
Ngenxa yemikhawulo yayo yesakhiwo, ubuhlalu belambu le-LED elixhumeke ngqo busetshenziswa ikakhulukazi emikhiqizweni yangaphandle enezikhala ezifana ne-P10, i-P16, ne-P20. Ubuhlalu belambu le-LED le-Surface-mount busetshenziswa kakhulu ezinhlelweni zangaphandle nangaphakathi ngenxa yesakhiwo sabo esijwayelekile, abakaki bensimbi abalungisekayo, nezinhlobo ezahlukahlukene. Kungakhathaliseki ukuthi i-P13.33 yangaphandle, i-P10, i-P8 nezinye izikhala, noma i-P1.875 yasendlini, i-P1.667, i-P1.53, i-P1.25 nezinye izinhlelo zokusebenza ezincane zesikhala, ubuhlalu besibani se-LED obubekwe phezulu bungahlangabezana nezidingo.
Amathemba okuthuthukiswa kobuhlalu besibani semojuli yesibonisi se-LED abonisa ukuthambekela okuhle. Iqhutshwa yizici eziningi ezifana nenqubekelaphambili yezobuchwepheshe, ukukhula kwesidingo semakethe nokusekelwa kwenqubomgomo, ukusebenza kobuhlalu besibani samamojula kuzoqhubeka nokuthuthuka futhi inkambu yesicelo izoqhubeka nokukhula. Ngokuzayo, sinesizathu sokukholelwa ukuthi ubuhlalu bemojuli yesibonisi se-LED buzodlala indima ebalulekile emikhakheni eminingi futhi balethe abantu umuzwa wokubuka onemibala eminingi.
