Ubuchwepheshe bokubonisa i-LED

Isibonisi se-LEDingenye yezinkambu eziyinhloko ze-LED, ezithuthuke ngokushesha eminyakeni yamuva.Okwamanje,Isikrini sokubonisa se-LEDinobuchwepheshe obuphambili bokukhiqiza kanye nenani eliphansi, ngakho-ke kunzima ngezinkampani zakwamanye amazwe ukuncintisana emakethe yezwekazi.Ngokwezibalo ezingaphelele, ngo-1998, kwakukhona abakhiqizi besikrini sokubonisa i-LED abangaphezu kuka-150 e-China, abakhiqiza cishe amamitha-skwele angu-50000 azo zonke izinhlobo zemibukiso, bazuza inani eliphumayo lama-yuan ayizigidi eziyizinkulungwane ezingu-1.4.Imboni ye-LED yenze impumelelo emangalisayo.Eminyakeni yamuva nje, ngokwesakhiwo somkhiqizo, ubuchwepheshe bokukhiqiza, ikhwalithi yomkhiqizo, izinga lokukhiqiza ngobuningi, isabelo semakethe, njll., iseduze neJapane, futhi ikleliswe endaweni yesithathu emhlabeni ilandela i-United States neJapane embonini ye-LED yomhlaba.Kule minyaka emihlanu edlule, isilinganiso sokukhula konyaka sifinyelele ngaphezu kwama-20%.Ngo-1997, imikhiqizo eyishumi ephezulu ye-optoelectronic yaseTaiwan yakleliswa yesine, enenani eliphumayo le-SGD 18870 million.I-Epistar Corp ithuthukise ngempumelelo ama-chips abomvu, aluhlaza naluhlaza okwesibhakabhaka ngezibani ezinombala ogcwele nezibonisi, ngokukhanya kokukhanya kwalawa mashiphu angaphezu kuka-70 mcd.Inkampani eyenza ukukhiqiza isebenzisa ubuchwepheshe be-MOVPE ukukhiqiza i-InGaAlp izinto ezikhanyayo ezikhanyayo nezicwebezelayo.I-Taiwan inezinkampani eziyisikhombisa ezikhiqiza ama-chips e-LED, akhiqiza ama-chips endabuko ahlukahlukene, ahlanganisa ngaphezu kuka-70% womkhiqizo womhlaba.

Ukusetshenziswa kweI-LEDivame kakhulu.Ngenxa ye-voltage yayo ephansi yokusebenza, ukusetshenziswa kwamandla okuphansi, imibala ecebile kanye nenani eliphansi, yamukelwa onjiniyela bakagesi nabacwaningi besayensi.Ezinsukwini zokuqala, imikhiqizo yendabuko yayisebenza kahle ngokukhanyayo, futhi amandla okukhanya ayevame ukuba ngama-mcd amaningana kuya kwamashumi.Bezilungele izinhlelo zokusebenza zasendlini, njengezinto zikagesi zasendlini, izinsimbi, izinto zokuxhumana, amakhompiyutha amancane namathoyizi.Ngenxa yokuthuthukiswa okukhulayo kobuchwepheshe bokufaka isicelo, amathuba amasha okufaka isicelo avele emikhiqizweni yendabuko.Izibani zikaKhisimusi ze-LED ezidumile, ezinomumo wazo wenoveli, izibani zikaKhisimusi ezikhokhiswa ngamadada, izibani zebhola ezimibalabala, nezibani zamafasitela eparele.Zinemibala, azinqamuki, futhi ziphephile ukusetshenziswa kwamandla kagesi aphansi.Muva nje, banemakethe eqinile eNingizimu-mpumalanga ye-Asia, njengeHong Kong, futhi bamukelwa kabanzi ngabantu.Bayasabisa futhi bashintsha imakethe kaKhisimusi ekhona manje ukuze bafake izibani zombani.Uhlobo lwezicathulo ezicwebezelayo oluthandwa yizingane, olusebenzisa i-LED ukuze lukhanyise lapho uhamba futhi ulele.Idonsa amehlo kakhulu, okuhlanganisa ukukhanya kwe-monochromatic nokukhanya kombala okabili.Mayelana nemikhiqizo yezimboni, izibani ze-LED zohlobo lwe-AD11 zisetshenziswa kakhulu kumakhabethe kagesi.Le mikhiqizo isebenzisa ukuhlanganiswa kwama-chip amaningi ukwenza umthombo wokukhanya, onemibala emithathu: obomvu, ophuzi kanye nohlaza.Ngemuva kokuthi i-capacitor icindezelekile, amandla kagesi angu-220V nama-280V angasetshenziswa.Ngokomkhiqizi wase-Jiangsu, ukuthengiswa konyaka kwenkampani kufinyelela ngaphezu kwe-10M, futhi idinga (200~300) ama-LED chips e-M njalo ngonyaka.Imakethe isenamandla okunwetshwa.Ngenxa yenkomba ekhanyayo esebenzayo, impilo ende yesevisi, ukusetshenziswa kwamandla okuphansi nezinye izici, ithandwa kakhulu kubasebenzisi futhi ingangena esikhundleni sayo yonke imikhiqizo yohlobo lwebhamuza ye-AD11.Ngamafuphi, imakethe yama-diode endabuko akhipha ukukhanya ngeke nje ithuthuke ngokukhula kwemikhiqizo yokuqala yohlelo lokusebenza, kodwa futhi ivule amathuba emakethe ezinhlelo zokusebenza ezintsha.
