Yintoni i-LED?
I-LED imele "i-Light Emitting Diode."Sisixhobo se-semiconductor esikhupha ukukhanya xa umsinga wombane udlula kuwo.Ii-LED zisetyenziselwa uluhlu olubanzi lwezicelo, kubandakanywa ukukhanya, iziboniso, izikhombisi, kunye nokunye.Baziwa ngokusebenza kakuhle kwamandla, ukuqina, kunye nobomi obude xa kuthelekiswa ne-incandescent okanye iibhalbhu ze-fluorescent.Ii-LED ziza ngemibala eyahlukeneyo kwaye zinokusetyenziswa kuluhlu olwahlukeneyo lweemveliso, ukusuka kwizibane ezilula zokubonisa ukuya kwiziboniso ze-elektroniki ezintsonkothileyo kunye nezibane zokukhanyisa.
Umgaqo wokukhanya kwe-LED
Xa ii-electron kunye nemingxuma ekudibaneni kwe-PN ye-diode ekhupha ukukhanya kwakhona iphinda idibane, ii-electron zitshintsha ukusuka kwinqanaba eliphezulu lamandla ukuya kwinqanaba eliphantsi lamandla, kwaye ii-electron zikhupha amandla amaninzi ngendlela yeefotoni ezikhutshwayo (amaza ombane), okukhokelela ekubeni i-electroluminescence.Umbala wokukhanya uhambelana nezinto eziphathekayo ezenza isiseko sayo.Ezona zinto ziphambili zibambekayo ezifana negallium arsenide diode ikhupha ukukhanya okubomvu, igallium phosphide diode ikhupha ukukhanya okuluhlaza, isilicon carbide diode ikhupha ukukhanya okutyheli, kunye negallium nitride diode ikhupha ukukhanya okuluhlaza.
Ukuthelekisa umthombo wokukhanya
I-LED: ukusebenza kakuhle kokuguqulwa kwe-electro-optical (phantse i-60%), eluhlaza kunye nokusingqongileyo, ubomi obude (ukuya kwiiyure ze-100,000), i-voltage ephantsi yokusebenza (malunga ne-3V), akukho kulahleka kobomi emva kokutshintsha ngokuphindaphindiweyo, ubungakanani obuncinci, isizukulwana esincinci sokushisa. , ukukhanya okuphezulu, okunamandla kunye nokuqina, Kulula ukufiphala, imibala eyahlukeneyo, i-beam egxininisiweyo kunye nezinzileyo, akukho kulibaziseka ekuqaliseni.
Isibane se-Incandescent: ukuguqulwa kwe-electro-optical ephantsi (malunga ne-10%), ubomi obufutshane (malunga neeyure ze-1000), ukushisa okuphezulu kokushisa, umbala omnye kunye nokushisa kombala ophantsi.
Izibane ze-Fluorescent: ukukhanya okuphantsi kwe-electro-optical conversion (malunga ne-30%), kuyingozi kwindalo (equlethe izinto ezinobungozi ezifana ne-mercury, malunga ne-3.5-5mg / iyunithi), ukukhanya okungaguqukiyo (i-voltage ephantsi ayikwazi ukukhanya), i-ultraviolet radiation, into edanyazayo, ukuqala kancinci Kancinci, ixabiso lezinto ezinqabileyo zomhlaba liyenyuka, ukutshintsha ngokuphindaphindiweyo kuchaphazela ixesha lokuphila, kwaye umthamo mkhulu.Izibane zokukhupha igesi ezinoxinzelelo oluphezulu: zidla amandla amaninzi, azikhuselekanga ukuzisebenzisa, zifutshane. ubomi, kwaye babe neengxaki zokuphelisa ubushushu.Ikakhulu isetyenziselwa ukukhanyisa kwangaphandle.
Iinzuzo ze-LED
I-LED yitshiphu encinci kakhulu efakwe kwi-epoxy resin, ngoko ke incinci kwaye ilula.Ngokubanzi, amandla ombane osebenzayo we-LED yi-2-3.6V, okwangoku esebenzayo yi-0.02-0.03A, kwaye ukusetyenziswa kwamandla akukho mkhulu kune
0.1W.Ngaphantsi kombane ozinzileyo kunye ofanelekileyo kunye neemeko zokusebenza zangoku, ubomi benkonzo ye-LED bunokuba bubude beeyure ze-100,000.
I-LED isebenzisa itekhnoloji ye-luminescence ebandayo, eyenza ubushushu obuphantsi kakhulu kunezibane eziqhelekileyo zamandla afanayo.Ii-LED zenziwe ngezinto ezingenabuthi, ngokungafani nezibane ze-fluorescent eziqukethe i-mercury, ezinokubangela ukungcola.Kwangaxeshanye, ii-LED zinokuphinda zisetyenziswe kwaye zisetyenziswe kwakhona.
Ukusetyenziswa kwe-LED
Njengoko itekhnoloji ye-LED iqhubeka nokukhula kwaye ikhula ngokukhawuleza, ngakumbi nangakumbi izicelo ze-LED zivela kubomi bethu bemihla ngemihla.Ii-LED zisetyenziswa ngokubanzi kwimiboniso ye-LED, izibane zendlela, izibane zemoto, imithombo yokukhanyisa, imihlobiso yokukhanyisa, izibane ze-LCD zesikrini, njl.
Ukwakhiwa kwe-LED
I-LED yi-chip ekhupha ukukhanya, i-bracket kunye neengcingo ezifakwe kwi-epoxy resin.Ikhaphukhaphu, ayinayo ityhefu kwaye inokumelana nokothuka okuhle.I-LED ine-conductivity yendlela enye, kwaye xa i-voltage ejikelezayo iphezulu kakhulu, iya kubangela ukuphuka kwe-LED.Isakhiwo esiphambili sokwakheka siboniswe kumzobo:
