Emva kweminyaka yophuhliso, isiboniso esiqhelekileyo se-anode ye-LED senziwe ikhonkco elizinzileyo lemizi-mveliso, elikhokelele ekwandeni komboniso we-LED.Nangona kunjalo, ikwanazo iingxaki, ubushushu obugqithisileyo besikrini kunye nokusetyenziswa kwamandla okugqithisileyo.Emva kwenkangeleko eqhelekileyo cathode LED ukubonisa amandla iteknoloji, iye yatsala ingqalelo enkulu kwimarike ukubonisa LED.Le ndlela yonikezelo lwamandla inokufezekisa ukonga amandla aphezulu angama-75%, ngoko yintoni itekhnoloji yobonelelo lwamandla ebonisa i-LED cathode eqhelekileyo?Ziziphi iingenelo zobu bugcisa?
Ziziphi iingenelo zeteknoloji yonikezelo lwamandla omboniso we-LED oqhelekileyo we-cathode
1. Yintoni umboniso we-LED oqhelekileyo we-cathode?
"I-cathode eqhelekileyo" ibhekiselele kwindlela yonikezelo lwamandla ombane oqhelekileyo.Enyanisweni, le yitekhnoloji yokonga amandla kwiziboniso ze-LED.Ibhekisa ekusebenziseni i-cathode eqhelekileyo ukunika amandla umboniso we-LED.I-B (ebomvu, eluhlaza, eluhlaza okwesibhakabhaka) yahlula unikezelo lwamandla, kwaye isasaza ngokuchanekileyo i-current kunye ne-voltage ye-R, G, B amaso isibane, kuba i-R, G, B (ebomvu, eluhlaza, eluhlaza) amaso esibane afuna ukusebenza kakuhle. i-voltage, kwaye yangoku yahlukile, Ngoko ke, i-current iya kuqala idlule kwi-bead yesibane, kwaye emva koko ifikelele kwipali engafanelekanga ye-IC, ukunciphisa ukuhla kwamandla ombane kunye nokunciphisa ukunyanzeliswa kwangaphakathi.
2. Uthini umahluko phakathi kwe-cathode eqhelekileyo kunye neziboniso ze-LED ze-anode eziqhelekileyo?
①.Iindlela ezahlukeneyo zobonelelo lwamandla:
Indlela yonikezelo lwamandla e-cathode esetyenziswa ngokuqhelekileyo kukuba i-current yokuqala idlula kwi-bead yesibane kwaye ifike kwipali engafanelekanga yesekethe edibeneyo, ukwenzela ukuba i-voltage yangaphambili ihla ibe yincinci kwaye i-on-resistance ibe yincinci.
I-anode eqhelekileyo ngoku equkuqelayo ukusuka kwibhodi ye-PCB ukuya kumaso wesibane, kwaye inika amandla ngokulinganayo ku-R, G, B (obomvu, oluhlaza, oluhlaza okwesibhakabhaka), ukuze ukuhla kwamandla ombane angaphambili kwisekethe ibe nkulu.
②.Umbane wobonelelo lwamandla wahlukile:
I-cathode eqhelekileyo, ukubonelela ngoku kunye ne-voltage ye-R, G, B (ebomvu, eluhlaza, eluhlaza okwesibhakabhaka), ngokulandelanayo.Ii-LED ezibomvu, eziluhlaza kunye neziluhlaza zineemfuno ezahlukeneyo zombane.I-voltage yezibane zesibane ezibomvu malunga ne-2.8V, kwaye i-voltage ye-blue and green beads imalunga ne-3.8V, lo mbane unokufikelela kumbane ochanekileyo kunye nokunikezelwa kwamandla.Ngenxa yeelahleko ezincinci, ukushisa okwenziwa ngumboniso we-LED ngexesha lokusebenza kuphantsi kakhulu.
I-cathode eqhelekileyo idinga ukunika i-R, G, B (ebomvu, eluhlaza, eluhlaza okwesibhakabhaka) unikezelo lwamandla olumanyeneyo olungaphezulu kwe-3.8V (njenge-5V).Ngeli xesha, i-voltage efunyenwe ngobomvu, eluhlaza kunye noluhlaza okwesibhakabhaka ifana ne-5V, ngelixa ibomvu, iluhlaza, I-voltage esebenza ngokufanelekileyo efunekayo ngamaso amathathu ezibane eziluhlaza ngezantsi kakhulu kune-5V.Ngokwefomula yamandla P=UI, phantsi kweemeko eziqhubekayo zangoku, ukuphakama kwamandla ombane, amandla amakhulu, oko kukuthi, ukusetyenziswa kwamandla amakhulu, ngelixa isiboniso se-LED sisebenza Ukushisa okungaphezulu kuveliswa kwinkqubo.
3. Kutheni ubushushu besiqhelo se-cathode isiboniso se-LED sisezantsi?
Imowudi ekhethekileyo yonikezelo lwamandla e-cathode yesikrini esibandayo yenza inkqubo yokubonisa i-LED ivelise ubushushu obuncinci kunye nokunyuka kobushushu obuphantsi.Ngaphantsi kweemeko eziqhelekileyo, ngexesha lokulinganisela okumhlophe kunye nokudlalwa kwevidiyo, ukushisa kwesikrini esibandayo malunga ne-20 ° C ephantsi kunombonakaliso wendabuko wangaphandle we-LED wemodeli efanayo.Phantsi kweenkcukacha ezifanayo kunye nokuqaqamba okufanayo, ubushushu bekhusi yesiqhelo cathode isiboniso LED ingaphezulu kwama-20 degrees ngaphantsi kunaleyo yesiqhelo anode imveliso ukubonisa LED, kunye nokusetyenziswa kwamandla 50% ngaphantsi kunaleyo anode eqhelekileyo iimveliso ukubonisa LED.
Ukushisa okuphezulu kwesikrini sokubonisa i-LED kunye nokusetyenziswa kwamandla okugqithisileyo kuye kwaba zizinto eziphambili ezichaphazela ubomi benkonzo yesikrini se-LED."Umboniso we-LED oqhelekileyo we-cathode" unokusombulula ezi ngxaki zimbini.
4. Ziziphi iingenelo zemiboniso ye-LED eqhelekileyo ye-cathode?
Ubonelelo lwamandla e-e luwonga ngokwenene amandla:
Iimveliso eziqhelekileyo ze-cathode zamkela itekhnoloji yokulawula amandla achanekileyo, ngokweempawu ezahlukeneyo ze-optoelectronic zemibala emithathu ebomvu ye-LED, eluhlaza kunye nohlaza okwesibhakabhaka, idityaniswe nenkqubo yolawulo ekrelekrele ye-IC kunye nemowudi yokuzinikela ezimeleyo, umbane ohlukeneyo we-LED kunye neesekethe zokuqhuba zichanekile. yabelwe, ukwenzela ukuba ukusetyenziswa kwamandla emveliso kuphezulu kakhulu.Iimveliso ezifanayo kwiimarike zigcina malunga ne-40%!
②.Ukonga amandla okwenene kuzisa umbala wokwenyani:
Indlela yokuqhuba i-cathode ye-LED esetyenziswa ngokuqhelekileyo inokulawula ngokuchanekileyo i-voltage, ngelixa inciphisa ukusetyenziswa kwamandla kunye nokuveliswa kobushushu, ubude be-LED abuyi kukhukuliseka ngexesha lokusebenza okuqhubekayo, kwaye umbala wokwenyani unokuboniswa ngokuzinzileyo!
③.Ukonga amandla okwenene kuzisa ubomi obude:
Ukusetyenziswa kwamandla kuyancipha, ukunyuka kweqondo lokushisa kwenkqubo kuncitshiswe kakhulu, amathuba okuba umonakalo we-LED uyancitshiswa ngokufanelekileyo, ukuzinza kunye nokuthembeka kwenkqubo yokubonisa yonke iphuculwe, kwaye ubomi benkonzo yenkqubo bandiswa kakhulu.
5. Zeziphi iintsingiselo kwiiteknoloji ezingalunganga eziqhelekileyo?
Inxulumene ne-cathode eqhelekileyo ye-LED ye-teknoloji yokubonisa njenge-LEDs, izixhobo zombane, kunye nee-ICs zomqhubi, ayivuthwanga njenge-chain ye-Ram LED.Ukongezelela, uchungechunge lwangoku lwe-cathode ye-IC aluphelelanga, kwaye umthamo wokuthengisa ngokubanzi awukho mkhulu.I-Ram isathatha i-80% yemarike.
Esona sizathu siphambili sophuhliso olucothayo lwetekhnoloji eqhelekileyo ye-cathode okwangoku lixabiso eliphezulu lemveliso.Ngokwesiseko sentsebenziswano yekhonkco lokubonelela, i-cathode eqhelekileyo ifuna intsebenziswano elungelelanisiweyo kuzo zonke iziphelo zekhonkco lezoshishino ezifana neechips, ukupakishwa, kunye neePCB, kwaye iindleko ziphezulu.
Ngeli xesha lemfuno ephezulu kakhulu yokonga amandla, ukuvela komboniso ocacileyo we-LED oqhelekileyo uye waba yindawo yenkxaso yokusukela kolu shishino.Nangona kunjalo, kusekho indlela ende yokufezekisa ukukhuthazwa okubanzi kunye nesicelo kwingqiqo enkulu, kwaye imizamo edibeneyo yoshishino lonke iyadingeka.Umboniso we-LED oqhelekileyo we-cathode ubandakanya ukusetyenziswa kwamandla ombane kunye neendleko zokusebenza, nto leyo yindlela yokuphuhlisa ukugcinwa kwamandla.Ngoko ke, ukugcinwa kwamandla kunye nokunciphisa ukusetyenziswa kuhambelana nomdla wabaqhubi be-LED kunye nokusetyenziswa kwamandla kazwelonke.
Ukujonga imeko yangoku, i-cathode eqhelekileyo ye-LED egcina amandla umboniso ayiyi kwandisa iindleko kakhulu xa kuthelekiswa nomboniso wendabuko, kwaye iya kugcina iindleko zokusetyenziswa kwixesha elizayo, ezifunyenwe kakuhle kwiimarike.
