Izindlela zokulungisa eziqondile zokunikezwa kwamandla kwesikrini sesibonisi se-LED
1. Lapho silungisa isiphakeli samandla sesikrini sesibonisi se-LED, okokuqala sidinga ukusebenzisa i-multimeter ukuze sithole ukuthi ingabe kukhona isifunda esifushane sokuhlukana kudivayisi ngayinye yamandla, njengebhuloho lokulungisa amandla, ishubhu lokushintsha, ishubhu yokulungisa amandla aphezulu enemvamisa ephezulu. , kanye nokuthi ngabe i-resistor yamandla aphezulu yini...Funda kabanzi -
Ukugcinwa kokuphakelwa kwamandla kwesikrini sesibonisi se-LED kungahlukaniswa ngezinyathelo ezimbili
(1) Uma kwenzeka ukucima kukagesi, 'bheka, nuka, buza, linganisa' Bheka: Vula igobolondo lesiphakeli sikagesi, hlola ukuthi i-fuse ishaywa yini, bese ubheka isimo sangaphakathi samandla kagesi.Uma kunezindawo ezishile noma izingxenye eziphukile ebhodini le-PCB lokuphakelwa kukagesi, i-fo...Funda kabanzi -
Umthamo wokulayisha ongemuhle wokunikezwa kwamandla kagesi we-LED
Umthamo ophansi wokulayisha ugesi uyiphutha elivamile, elivame ukwenzeka kugesi wakudala noma osebenza isikhathi eside.Izizathu eziyinhloko ukuguga kwezingxenye ezihlukahlukene, ukusebenza okungazinzile kwamashubhu okushintsha, nokwehluleka ukuchithwa kokushisa okufika ngesikhathi.Kufanele kugcizelelwe ekuhloleni ukushisa...Funda kabanzi -
Ukuhlaziywa Kwamaphutha Avamile Ekunikezeni Amandla Okubonisa I-LED
(1) I-Fuse ivuthelwa Ngokuvamile, uma i-fuse ishaywa, ibonisa ukuthi kunenkinga ngesekethe yangaphakathi yokunikezwa kwamandla.1. Isifunda esifushane: Iphutha lesifunda esifushane lenzeka ohlangothini lomugqa, okwenza i-fuse iphule ngokushesha;2. Ukugcwala: Uma umthamo wamanje weqa umkhawulo wamanje we...Funda kabanzi -
Izici Zobuchwepheshe Zesikrini Se-LED Sokuboniswa Kwemishini KaRubik's Cube Rotating
Isikrini se-LED esizungeza iphiko elincane, esaziwa nangokuthi isikrini seCube sikaRubik esijikelezayo se-LED, sisetshenziswa kabanzi ekukhangiseni ngaphandle, ezikhumulweni zezindiza, emahholo emibukiso nakwezinye izindawo.Ukubambisana komshini ngezikrini ezinkulu kunemiphumela enamandla yezinhlangothi ezintathu.Ngokuvamile, iCube kaRubik iyazungeza...Funda kabanzi -
Indlela yokuxazulula iphethini ye-Moore ekudubuleni okubonakalayo kwezikrini zokubonisa ze-LED
Njengamanje, ngokwanda kancane kwezibonisi ze-LED ezenzakalweni, ezitudiyo, nakwezinye izinhlelo zokusebenza, izibonisi ze-LED kancane kancane seziphenduke insakavukela yengemuva elibonakalayo lokudubula.Kodwa-ke, lapho usebenzisa okokusebenza kwezithombe nekhamera ukuze uthwebule isikrini se-LED, isithombe sokuthwebula ...Funda kabanzi -
Ungakala futhi ucindezele kanjani ukugeleza kwamandla okubonisa i-LED
1.Ukukhiqizwa kwamandla kagesi Imithombo yethu yamandla evamile ihlanganisa imithombo yamandla alayini kanye nemithombo yamandla ashintshayo, okuphuma kwayo amandla kagesi e-DC atholakala ngokulungisa, ngokuhlunga, nangokuzinzisa amandla kagesi e-AC.Ngenxa yokuhlunga okungalungile, amasiginali wemfuhlumfuhlu aqukethe izingxenye zezikhathi ezithile nezingahleliwe azoba...Funda kabanzi -
Yiziphi izinzuzo ze-COB uma ziqhathaniswa ne-SMD?
I-SMD isifinyezo se-Surface Mounted Device, ehlanganisa izinto ezifana nezinkomishi zamalambu, abakaki, ama-chips, i-lead, ne-epoxy resin ekucacisweni okuhlukene kobuhlalu besibani, bese yenza amamojula wokubonisa ama-LED ngokuwahlanganisa ebhodini le-PCB ngendlela amapheshana.I-SMD ibonisa ijene...Funda kabanzi -
I-LED ukukhanya kokuqhuma
Ngenxa yokuthi i-LED ingumthombo wokukhanya okuqinile obandayo, inobuhle bokuguqulwa kwe-electro-light ukusebenza kahle, ukudlulisa ukushisa okuncane, ukusetshenziswa kwamandla amancane, kanye ne-voltage esebenzayo iphephile kagesi ephansi, impilo ende yesevisi nezinye izinzuzo, kanye nokusetshenziswa kwamandla okuphansi.Ngakho-ke I-e ekahle kakhulu ...Funda kabanzi -
