I-Oremark UV Bead Structure

Ingabe abantu abaningi bazofuna ukwazi isakhiwo sangaphakathi sobuhlalu besibani se-diode? Kunjalo naku-Xiaobian, ngakho-ke ngicele ngokukhethekile ochwepheshe ukuthi bahlanganise ulwazi olunjalo ukuze uthole ireferensi yakho. I-UV ukukhanya diode ibhekisela. Ukukhanya kwe-Ultraviolet kuvame ukusetshenziselwa ukukhomba ukuthi ama-banknote awakhohlisi yini, futhi ezinye izinto zokukhanyisa ze-ultraviolet diode zithandwa kakhulu kuma-nightclub nasemaphathini. Zisetshenziselwa ukwenza izinto ze-fluorescent zikhiphe ukukhanya okugqamile. Isakhiwo sayo esiyisisekelo siyi-semiconductor ekhazimulayo ka-electrostatic, ebekwe eshalofini eliholayo, bese ivalwa nge-epoxy resin eyizungezile ukuze kuvikelwe intambo ewumgogodla wangaphakathi. Ngakho - ke. Ingxenye eyinhloko ye-diode ephumayo iyi-chip ehlanganisa i-semiconductor yohlobo lwe-P kanye ne-N -type semiconductor. Kukhona ungqimba olushintshayo phakathi kwe-semiconductor yohlobo lwe-P kanye ne-N -type semiconductor, ebizwa ngokuthi i-PN knot. Kufindo le-PN lezinto ezithile ze-semiconductor, umthwalo omncane -in -load kanye nesithwali esiningi sikhululwa lapho isithwali sikhululwa ngendlela yokukhanya, ukuze amandla kagesi aguqulwe ngokuqondile emandleni okukhanya kumandla okukhanya. I-Pn knot plus reverse voltage, inkampani yenethiwekhi embalwa kunzima ukuyijova, ngakho ayikhiphi ukukhanya. Le diode eyenziwe ngokujova isimiso sokukhanyisa i-electrophoretic ibizwa ngokuthi i-luminous diode, eyaziwa ngokuthi yi-LED. Uma isesimweni esihle sokusebenza (okungukuthi, iziphetho ezimbili kanye ne-voltage ephozithivu), i-current igeleza isuka ku-anode ye-LED iye ku-cathode, amakristalu e-semiconductor akhipha ukukhanya kusuka ku-ultraviolet kuya kumbala we-infrared. Izici zobuchwepheshe ze-ultraviolet diode yokukhanya; 1) Ukukhanya okunsomi okungu-5mm kusebenzisa okupakishwayo kwengilazi namagobolondo engxube ye-nickel-plated, athuthukisa ngokwengeziwe ukukhanya kokukhanya okunsomi, anciphise ukubola kokukhanya okunsomi, andise impilo yesevisi yokuphila kwesevisi, futhi andise impilo yesevisi. 2) Izikhonkwane ezimbili zisebenzisa ubuchwepheshe begolide. 3) Amandla aphezulu ngokomzwelo. 4) Ikhwalithi ezinzile futhi enokwethenjelwa.
