Eminyakeni yamuva, ngenxa yokuthuthuka kobuchwepheshe nokusebenza kahle, ukusetshenziswa kwama-LED kuye kwanda kakhulu;ngokuthuthukiswa kwezinhlelo zokusebenza ze-LED, isidingo semakethe sama-LED sithuthukile futhi ngasendleleni yamandla aphezulu kanye nokukhanya okuphezulu, okwaziwa nangokuthi ama-LED aphezulu..

　　Ngokuklanywa kwama-LED anamandla amakhulu, iningi labakhiqizi abakhulu njengamanje basebenzisa ama-DC LEDs we-DC anosayizi omkhulu owodwa njengezisekelo zabo.Zimbili izindlela, eyodwa iyisakhiwo esivundlile esivamile, kanti enye iyisakhiwo esima mpo.Ngokuqondene nendlela yokuqala, inqubo yokukhiqiza icishe ifane naleyo yohlobo olujwayelekile lwamasayizi amancane.Ngamanye amazwi, isakhiwo se-cross-sectional of the two siyafana, kodwa sihlukile ku-die-size-size, ama-LED aphezulu adinga ukusebenza kuma-currents amakhulu.Ngezansi, idizayini encane yama-electrode e-P ne-N engalinganiseli izodala umphumela wokuminyana wamanje ongathi sína (Ukuminyana kwamanje), okungeke kwenze i-chip ye-LED ingafinyeleli ekukhanyeni okudingwa umklamo, kodwa futhi kulimaze ukwethembeka kwe-chip.

Yiqiniso, kubakhiqizi be-chip / abenzi be-chip, le ndlela inokuhambisana okuphezulu kwenqubo (Ukuhambisana), futhi asikho isidingo sokuthenga imishini emisha noma ekhethekile.Ngakolunye uhlangothi, kubenzi besistimu ephansi komfula, ukuhlanganiswa kwe-peripheral, Okufana nokuklama kokunikezwa kwamandla, njll., umehluko awumkhulu.Kodwa njengoba kushiwo ngenhla, akulula ukusabalalisa okwamanje ngokufanayo kuma-LED amakhulu.Uma usayizi mkhulu, unzima kakhulu.Ngesikhathi esifanayo, ngenxa yemiphumela yejometri, ukusebenza kahle kokukhishwa kokukhanya kwama-LED amasayizi amakhulu kuvame ukuphansi kunamancane..Indlela yesibili iyinkimbinkimbi kakhulu kuneyokuqala.Njengoba ama-LED wamanje okuhweba aluhlaza cishe wonke akhule ku-substrate yesafire, ukuze ashintshele esakhiweni esiqondile sokuqhuba, kufanele kuqala ahlanganiswe ne-conductive substrate, bese i-non-conductive I-substrate yesafire isusiwe, bese inqubo elandelayo. kuqediwe;ngokwemibandela yokusabalalisa kwamanje, ngoba esakhiweni esiqondile, kunesidingo esincane sokucabangela ukuqhutshwa kwe-lateral, ngakho-ke ukufana kwamanje kungcono kunesakhiwo sendabuko esivundlile;ngaphezu kwalokho, okuyisisekelo Ngokwezimiso zomzimba, izinto ezine-conductivity kagesi ezinhle nazo zinezici ze-high conductivity ezishisayo.Ngokufaka esikhundleni se-substrate, siphinde sithuthukise ukuchithwa kokushisa futhi sinciphise izinga lokushisa le-junction, okuthuthukisa ngokungaqondile ukusebenza kahle okukhanyayo.Kodwa-ke, okubi kakhulu kwale ndlela ukuthi ngenxa yokwanda kwenqubo eyinkimbinkimbi, izinga lokukhiqiza liphansi kunesakhiwo sezinga lendabuko, futhi izindleko zokukhiqiza ziphezulu kakhulu.
