imvelaphi eholelekile
Ngawo-1960, izisebenzi zesayensi nezobuchwepheshe zakha ama-diode akhipha ukukhanya kwe-LED zisebenzisa isimiso se-semiconductor PN junction light-emitting.I-LED eyakhiwe ngaleso sikhathi yenziwe nge-GaASP, futhi umbala wayo wawubomvu.Ngemuva kweminyaka ecishe ibe ngu-30 yokuthuthuka, i-LED eyaziwayo ingakhipha okubomvu, ...Funda kabanzi -
Inqubo yokufaka kanye nendlela yokufaka yesibonisi esiholayo
1. Inhlolovo yendawo Lokhu kusho ukuthi ngaphambi kokufakwa kwezinye izikrini zokubonisa ezihamba ngaphandle, kufanele zihlolelwe indawo ethile, i-topography, ububanzi bemisebe ekhanyayo, ukwamukela ukukhanya nezinye izinhlaka.Ukuze uqinisekise ukufakwa kahle kwamabhodi ezikhangiso, kuyadingeka ukuthi...Funda kabanzi -
Ukuhlaziywa kolwazi lwamandla esibonisi esiholayo
I-capacitor yisitsha esikwazi ukugcina ukushaja kagesi.Yakhiwe ngamashidi amabili ensimbi asondelene ndawonye, ahlukaniswe yi-insulating material.Ngokwezinto ezahlukahlukene zokuvikela, ama-capacitor ahlukahlukene angenziwa.Okufana nalokhu: i-mica, i-porcelain, iphepha, ama-electrolytic capacitors, njll.Funda kabanzi -
