Iyini I-chip ye-LED?

Iyini i-chip ye-LED? Yiziphi izici zayo? Ukwenziwa kwe-chip ye-LED ngokuyinhloko ukwakha i-electrode yokuxhumana ye-Ohm esebenzayo nethembekile, futhi ingahlangabezana nokwehla kwamandla kagesi amancane phakathi kwezinto ezifinyelelekayo futhi inikeze amaphedi emigqa yokushisela. Ngasikhathi sinye. Izindlela ze-vacuum steam plating ngokuvamile zisetshenziselwa inqubo ye-cross-membrane. I-4Pa iphakeme futhi ayinamuntu. Ngaphansi kwe-vacuum ephezulu, sebenzisa ukushisisa kwe-resistor noma izindlela zokushisisa i-electronic beam ukuze uncibilikise into. I-chip ye-Shenzhen LED, futhi ngaphansi kwengcindezi yomoya ephansi, i-BZX79C18 iba amadiphozi omusi wensimbi ebusweni bezinto ezibonakalayo. Ngokuvamile esetshenziswa P -type contact metals kuhlanganise AUZN, AUZN kanye nezinye ingxubevange. Insimbi yokuxhumana ohlangothini lwe-N ivamise ukusebenzisa i-AUGENI ingxubevange. Ungqimba lwe-alloy olwakhiwe ngemva kokumboza nalo ludinga ukudalulwa ngangokunokwenzeka ngenqubo yokuqoshwa kwe-optical, ukuze ungqimba lwe-alloy lwesokunxele lukwazi ukuhlangabezana nezidingo zama-electrode othintana nawo aphansi we-ohm asebenzayo kanye namaphedi ashiselwe. Ngemuva kokuthi inqubo ye-lithography isiphelile, kufanele idluliswe ngenqubo ye-alloyization, futhi i-alloyization ngokuvamile ingaphansi kokuvikelwa kwe-H2 noma i-N2. Isikhathi kanye nezinga lokushisa kwe-alloy kuvame ukunqunywa ngokuya ngezinto ezifana nezici ezibonakalayo kanye nohlobo lwesithando somlilo wengxubevange. Yiqiniso, uma inqubo ye-electrode ye-blue and green kanye namanye ama-chips iyinkimbinkimbi, kuyadingeka ukwandisa ukukhula kwefilimu ye-passivation, inqubo ye-plasma etching, njll. Ukuhlukaniswa kwe-chip ye-LED —— Yiziphi izigaba zama-GB chips nama-LED chips? Incazelo ye-GB chip nezici 1. Incazelo: I-Glue bonding chip; le chip ingeyomkhiqizo we-I-benefit okhethekile we-UEC. 2. Izici: (1) Isisekelo sesafire esikhanyayo singena esikhundleni se-suction GAAS substrate. Amandla ayo okukhiphayo angaphezu kokuphindwe kabili kune-chip yendabuko ye-AS (ABSORBable Structure). (2) I-chip ikhanya nhlangothi zonke, inomdwebo omuhle kakhulu wephethini. (3) Mayelana nokukhanya, ingakanani i-chip ye-LED, ukukhanya kwayo kukonke kudlule izinga le-TS chip (8.6mil). (4) Isakhiwo se-Dual-electrode, ukumelana kwayo okuphezulu kwamanje kufanele kube kubi kancane kune-TS single -electrode chip. Usayizi we-chip we-LED uhlukaniswe ngama-chips wamandla amancane, ama-chips aphakathi kwamandla kanye nama-high-power chips ngokusho kwamandla angahlukaniswa ngama-chips amancane wamandla. Ngokwezidingo zamakhasimende, ingahlukaniswa ngezinga le-single-tube, izinga ledijithali, izinga le-matrix yamachashazi, ukukhanya komhlobiso nezinye izigaba. Ngokuqondene nosayizi othize we-chip, kuncike ezingeni langempela lokukhiqiza labakhiqizi abahlukene be-chip. Azikho izidingo eziqondile. Uma nje inqubo idlula, ama-chips amancane angakhuphula ukukhishwa kweyunithi futhi anciphise izindleko. Ukusetshenziswa kwamanje kwe-chip empeleni kuhlobene nokuminyana kwamanje kokugeleza ku-chip. I-chip isebenzisa imisinga emincane yamanje, inxusa le-chip linomthamo omkhulu wamanje, futhi ukuminyana kweyunithi yawo kuyafana ngokuyisisekelo. Uma kucatshangelwa ukuthi ukuchithwa kokushisa kuyinkinga eyinhloko ngaphansi kwamanje amakhulu, abakhiqizi be-chip ye-LED, ngakho-ke ukusebenza kahle kwayo okukhanyayo kuphansi kunamanje okuncane. Ngakolunye uhlangothi, ngenxa yokwanda kwendawo, ukumelana komzimba we-chip kuzokwehla, ngakho-ke i-voltage yesiqondiso esihle izokwehla.
