1. Intshayelelo
Inxalenye ephambili yomboniso we-LED kukukhanya kwe-Diode ekhanyayo (i-LED), ethi, injenge-diode esemgangathweni, inomsebenzi ochanekileyo ofanelekileyo (i-Anode). Ngeemfuno ezikhulayo zentengiso zentengiso ye-LED, njengokuphila, ukungqinelana nokusetyenziswa kwamandla, ukusetyenziswa kwethethode yesiqhelo kunye nokulungiswa kwe-Athodes kunye ne-Atocodes eqhelekileyo kuye kwaxhaphake kwizicelo ezahlukeneyo. Ukukunceda ukuba uqonde ngcono ezi teknoloji zimbini, eli nqaku liza kubonelela ngamagqabantshintshi egcwele ulwazi lwabo olufanelekileyo.
2. Umahluko ophambili phakathi kwe-cathode eqhelekileyo ne-anode eqhelekileyo
Kwiseti yesiqhelo ye-cathode, zonke i-Cathodes ze-Chethodes (i-terminal engalunganga) Yabelana ngoqhagamshelo oluqhelekileyo, ngelixa i-anode nganye ilawulwa ngokukodwa yi-voltage. Ngokwahlukileyo, ukumiselwa okuqhelekileyo kwe-Anode Qhagamshela zonke ii-HOODS (i-terminals elungileyo) ukuya kwindawo ekwabelwana ngayo, kunye ne-canciede nganye ilawulwa ngolawulo lwevolthi. Zombini iindlela zisetyenziswa kwiimeko ezahlukeneyo zesekethe.
Ukutya umbane:
Kwi-anode eqhelekileyo ye-anode, i-terminal eqhelekileyo iqhagamshelwe kwinqanaba eliphezulu le-voltage kwaye ihlala isebenza naphi na xa kufuneka ivolthi ephezulu. Kwelinye icala, kwi-cathode ye-cathode ye-cathode, i-terminal eqhelekileyo iqhagamshelwe emhlabeni (i-GNN), kwaye kuphela i-diode ekhethekileyo kuphela yokufumana i-voltage ephezulu ukuze isebenze, inciphise ukusetyenziswa kwamandla. Olu kuncitshiswa kokusetyenziswa kwamandla luyingenelo ikakhulu kwii-LEDs ezisetyenziselwa ixesha elide, njengoko kunceda ukuthoba ubushushu besikrini.
Ubunzima besekethe:
Ngokubanzi, kwizicelo zobunjineli bobunjineli, i-cathode eqhelekileyo ye-cathode diode idla ngokuntsonkotha kunemijikelezi ye-Anode eqhelekileyo. Uqwalaselo lwe-Anode oluqhelekileyo aludingi kwimigca emininzi yevolthi ephezulu yokuqhuba.
I-3. I-Cathode eqhelekileyo
3.1 Yintoni eyona nto iqhelekileyo ye-cathode
Uqwalaselo lwe-Kathode Cothodey luqala ukuba i-terminals engeyiyo (i-CEBSDES) yee-LED iqhagamshelwe kunye. Kwisekethe eqhelekileyo yesiqhelo, yonke i-LEDS okanye ezinye izinto eziqhutywa ngamandla zidityaniswe kwinqaku elisabelweyo, ezihlala zibizwa ngokuba "kumhlaba" (GND "okanye i-thehode eqhelekileyo.
3.2 Umgaqo wokuSebenza we-Cathode eqhelekileyo
Ukuhamba kwangoku:
Kwisekethe eqhelekileyo yesiqhelo, xa enye okanye engaphezulu yemveliso yokubonelela ngekhompyutha i-voltage ephezulu, ii-LEDS ezihambelana okanye izinto ezihambelana nazo okanye ii-anodes zenziwa. Okwangoku, ukuhamba ngoku kwi-Cathode eqhelekileyo (GND) kwezi zinto zisebenzeleyo 'inamanade, zenze ukuba zikhanyise okanye zenze imisebenzi yazo.
Lawula i-Logic:
Isekethe elilawulayo lilawula imeko ye-LED nganye okanye ezinye izinto (okanye ngaphandle, okanye ezinye izinto ezisebenzayo) ngokutshintsha inqanaba le-voltage (ephezulu okanye eliphantsi) kwizikhululo zevolda. Kwisekethe eqhelekileyo yesiqhelo, inqanaba eliphezulu libonisa ukuba isebenze (ukukhanya okanye ukwenza umsebenzi), ngelixa inqanaba eliphantsi libonisa i-Deactivation (ayisebenzi okanye ayisebenzi okanye ayisebenzi umsebenzi).
4. I-Anode eqhelekileyo
4.1Yintoni eqhelekileyo
Uqwalaselo oluqhelekileyo lwe-Anode luthetha ukuba iitsinali (i-Inamade) ze-LED zidibene kunye. Kwisekethe enjalo, zonke izinto ezinxulumene noko (ezinjenge-Leds) zinama-ANEDEST kwindawo eqhelekileyo ye-onode, ngelixa i-cathode yecandelo lecandelo ngalinye liqhagamshelwe kwisekethe eyahlukileyo kwisekethe eyahlukileyo.
4.2 UMGAQO-NKQUBO WOKUGQIBELA WOBUCHULE BOKUGQIBELA
Ulawulo lwangoku:
Kwisekethe eqhelekileyo ye-ALODO, xa enye okanye engaphezulu yemveliso yokuhambisa i-voltage, indlela yenziwa phakathi kwe-Mathode ye-LOODE ye-LOPODE okanye i-Anode eQhelekileyo kwi-atode, kubangela ukuba icandelo likhanyisele okanye lisebenze. Kwelinye icala, ukuba i-terminal yemveliso ikwi-voltage ephezulu, ayinakukwazi ukudlula, kwaye icandelo alikhanyisi.
Ukuhanjiswa kwe-voltage:
Kwizicelo ezinjengemiboniso ye-Anode ye-Anode ye-Anode, kuba zonke i-ed Adses zidityaniswe kunye, zabelana ngomthombo wevolthi efanayo. Nangona kunjalo, i-cathomade nganye ye-LED ilawulwa ngokuzimeleyo, ivumela ulawulo oluchanekileyo malunga nokukhanya kwe-LED nganye ngokuhlengahlengiswa kwemveliso yemveliso kwaye okwangoku kwisekethe yokulawula.
