Izibane ze-LED zinokukhula ngokukhawuleza, zibonwa luluntu, kwaye zinconywa lilizwe. Izicelo zibandakanya: izibane ze-LED kwiivenkile zempahla, izibane ze-LED kwiivenkile ezizodwa, izibane ze-LED kwiivenkile zamakhonkco, izibane ze-LED kwiihotele, njl.
Iimpawu ezizodwa zezibane ze-LED zezi:

1. Ubungakanani obuncinci, ubungakanani be-chip eyodwa yamandla aphezulu e-LED ngokuqhelekileyo yi-1 ye-square millimeter, kunye nempahla yokupakisha yangaphandle, ububanzi be-LED buhlala buziimilimitha ezimbalwa, kunye ne-multi-chip exutywe ukukhanya kwe-LED idibanisa ezininzi. Iitshiphusi ze-LED. inkulu kancinci. Oku kuzisa iqondo eliphezulu lokuguquguquka kuyilo lwezixhobo zokukhanyisa. Izixhobo ze-LED zingenziwa zibe yindawo yokukhanya, umgca okanye indawo yokukhanya ngokweemfuno, kunye nobukhulu bezibane zinokuthi zenziwe ngokwezifiso ngokweempawu zesakhiwo sokwakha, ukwenzela ukuba kube ngcono ngakumbi ukufezekisa umphumo wokubona. Ukhanyiso ke, ingelulo ukukhanya. Izakhiwo ezininzi zanamhlanje zisebenzisa izinto ezintsha ezifana neendonga zangaphandle zeglasi, nto leyo eyenza indlela yokukhanyisa yangaphandle yemveli ngokuthe ngcembe ithathelwe indawo yindlela yokukhanyisa yangaphakathi, kwaye i-LED iyona nto ikhethekileyo yokukhanyisa kwangaphakathi, kwaye iNceda ekunciphiseni ukuphazamiseka kokukhanya kunye neengxaki zokungcola ukukhanya.

Okwesibini, i-LED inombala ocebileyo, kwaye i-monochromaticity yokukhanya okukhutshiweyo ilungile. I-monochromaticity yokukhanya okukhutshiweyo kombala omnye we-LED ingcono, echongwa ngumgaqo wokukhanya wokukhanya kwe-chip ye-LED. Ngokusebenzisa izinto ezahlukeneyo zokukhanyisa ukukhanya, ukukhanya kwe-monochromatic kwemibala eyahlukeneyo kunokufumaneka. Ukongeza, ngokwesiseko sokukhanya okuluhlaza okwesibhakabhaka, kunye neephosphors eziMthubi zinokusetyenziselwa ukufumana ii-LED ezimhlophe ezinobushushu obunemibala eyahlukeneyo, okanye ngokufaka iitshiphusi ezintathu ezinombala omnye we-LED obomvu, oluhlaza kunye noluhlaza okwesibhakabhaka kwi-LED enye, kunye nokusebenzisa okuhambelanayo. uyilo lwe-optical ukuqonda ukuxubana kokukhanya kwemibala emithathu.

Okwesithathu, i-LED inokubona utshintsho olukhawulezayo kunye nolwahlukeneyo kumbala okhanyayo. Njengoko kukhankanyiwe ngasentla, ukukhanya okumhlophe kunokufunyanwa ngokufaka iitshiphusi ze-LED ezinombala obomvu, oluhlaza kunye noluhlaza okwesibhakabhaka kunye kunye nokuxuba ukukhanya okunemibala emithathu. Ukuba silawula iitshiphusi ezibomvu, eziluhlaza kunye nebhlowu ngokwahlukeneyo, sinokutshintsha umyinge wemibala emithathu yokukhanya kwisibane esiphumayo, ukuze siqonde utshintsho lombala okhanyayo we-LED yonke. Ngale ndlela, i-LED ifana ne-palette, enokuthi ilungiswe kwimibala eyahlukeneyo yokukhanya ngokweemfuno ezahlukeneyo, ezingenakwenzeka kwimithombo yokukhanya yendabuko. Ii-LED ziphendula ngokukhawuleza kwaye zilula ukulawula, ngoko ziyakwazi ukufezekisa utshintsho olukhawulezayo kunye nolwahlukeneyo kumbala okhanyayo. Singasebenzisa eli nqaku le-LEDs ukwakha iziphumo ezininzi eziguqukayo.

Okwesine, i-LED ingasetyenziselwa ukwakha iipateni ezahlukeneyo. Ngenxa yobungakanani obuncinci, ubume obuqinileyo kunye nexesha elifutshane lokuphendula le-LED, sinokusebenzisa ii-LED ukwakha imizobo ethile; emva koko udibanise le mizobo ukuphumeza iziphumo ezithile zoyilo. Ngoku, ezitalatweni nasezindleleni zesixeko, sinokubona iipateni ezininzi ezisicaba okanye imizobo enemigangatho emithathu eyakhiwe yi-LED, enokufikelela kwiziphumo ezimangalisayo. Ukongeza, sinokuqhuba ulawulo oluphambili lwe-LED, kwaye sisebenzise lonke udonga lwangaphandle lwesakhiwo njengomboniso oguqukayo wesikrini.

5. I-LED inobomi obude, impendulo ekhawulezayo, kwaye inokutshintshwa kunye nokucima ngokuphindaphindiweyo. Ubomi be-LEDs obuphezulu bunokufikelela iiyure ezingaphezu kwe-50,000 phantsi kweemeko eziqhelekileyo zokusebenza, kwaye impendulo ye-LED ikhawuleza kakhulu. Ukongeza, sinokutshintsha ngokuphindaphindiweyo kwaye sivale ii-LED ngaphandle kokuchaphazela kakubi ubomi babo okanye ukusebenza kwazo. Oku kwahluke kakhulu kwimithombo yokukhanya yemveli. Ukuba isibane esiqhelekileyo se-incandescent siguqulwa ngokuphindaphindiweyo kwaye sivaliwe, ubomi baso buya kuncipha ngokukhawuleza; isibane esiqhelekileyo se-fluorescent siya kubangela ilahleko yezinto ezikhupha i-electrode ngalo lonke ixesha sivulwa kwaye sicinywa, ngoko ke ukutshintshwa rhoqo kuya kukhokelela ekunciphiseni ngokukhawuleza kwexesha lokuphila kwesibane. Izibane zokukhutshwa kwegesi ephezulu, ukutshintshwa ngokuphindaphindiweyo kuya kuba nefuthe elibi kakhulu kwi-electrodes yesibane. Ngaphezu koko, olu hlobo lomthombo wokukhanya alukwazi ukuphumeza ukuqala okushushu, oko kukuthi, isibane sifuna ukupholisa ixesha elithile emva kokuba sicinywe ngaphambi kokuba siqalise kwakhona. . Ke ngoko, kwezinye iziphumo zokukhanyisa ezifuna ukutshintshwa ngokuphindaphindiweyo, ii-LED zineenzuzo ezizodwa.
