Ifomu Lokuxhuma Ubuhlalu Besibani Se-LED, Isixazululo Esivamile Sokuhluleka Kwe-LED Amamojula Okukhipha Ukukhanya

Ubuhlalu besibani se-LED Izindlela ezijwayelekile zokuxhuma 1. Ifomu lokuxhuma lilonke (1) Amafomu ochungechunge olulula Ngokuvamile kanye namafomu ochungechunge olula oxhumano lwe-LED1 LEDN axhunywe ekuqaleni nasemsileni, kanti amanje agelezayo phakathi ne-LED ayalingana. Kuma-LED wokucaciswa okufanayo nama-batches, nakuba i-voltage ku-LED eyodwa ingase ibe nomehluko omncane, ngoba i-LED iyidivayisi yamanje, ingaqinisekisa ukuthi ukuqina kwayo okukhanyayo kuyavumelana, kubambe lokhu, amafomu ochungechunge olula amafomu okwakheka. I-LED inezici zesekethe elula nokuxhumana okulula. Kodwa-ke, ngenxa yokusetshenziswa kochungechunge, lapho enye ye-LED ivela, zonke izibani ze-LED zizocinywa, okuzothinta ukuthembeka kokusetshenziswa. (2) Amafomu ochungechunge e-two-pole diode nenhlanganisela ye-Qina diode axhunywe ochungechungeni oluthuthukisiwe lokuxhumana lwe-Qiner diode ngokuhambisana. Kule ndlela yokuxhuma, i-voltage yokuwohloka ye-Zina diode ngayinye iphakeme kune-voltage yokusebenza ye-LED. Uma usebenza ngokujwayelekile, ngenxa yokuthi i-Qina diode VD1 VDN, yamanje ihamba ngokuyinhloko ku-LED1 LEDN. Uma i-LED eyonakele ochungechungeni lwe-LED ibangelwa Ngaphezu kwe-LED enephutha, amanye ama-LED asenawo ama-currents ngokusebenzisa kwamanje nokukhanya. Le ndlela yokuxhuma ithuthukiswa kakhulu mayelana nokuqhathaniswa okuthembekile mayelana nokuthembeka. Ifomu elihambisanayo lilonke (1) Ifomu elihambisanayo elilula Elilula futhi lixhumekile le-LED1 le-LEDN lekhanda nomsila ngokuhambisana, i-LED ngayinye ilingana ne-LED ngayinye. Ingabonakala ezicini ze-LED. Ingeyedivayisi yamanje, futhi izinguquko ezincane ku-voltage engezwe ku-LED zizodala ushintsho olukhulu lwamanje. Ngaphezu kwalokho, ngenxa yokulinganiselwa kobuchwepheshe bokukhiqiza be-LED, ngisho nenqwaba efanayo yama-LED, umehluko ekusebenzeni ungokwemvelo, ngakho-ke uma i-LED1 LEDN isebenza, noma ubani osebenzisa i-LED ngayinye akalingani. Kungabonakala ukuthi ukusatshalaliswa okungalingani kwe-LED ngayinye yamanje kungabangela impilo ye-LED yamanje ukuthi ibe nkulu kakhulu, futhi ishise imbala. Nakuba le ndlela yokuxhuma ilula. Kodwa ukwethembeka akuphakeme, ikakhulukazi izinhlelo zokusebenza esimweni senani elikhulu lama-LED. (2) Ifomu elihambisanayo lokufanisa okuzimele lihloselwe ukwethembeka kokufana okulula. Ifomu elihambisanayo lokufanisa okuzimele liyindlela enhle. I-LED ngayinye ngale ndlela inamanje okulungiswayo okwamanje (i-drive Voutput terminal iyi-L1 Ln, ngokulandelana), futhi iqinisekise ukuthi yamanje egeleza nge-LED ngayinye ingaphakathi kwebanga lezidingo zayo, nemiphumela emihle yokushayela, i-LED eyodwa, i-LED eyodwa. Ukuvikela kuqedile, akuthinti omunye umsebenzi we-LED uma amaphutha, futhi kungafanisa izici zama-LED anomehluko omkhulu. Inkinga eyinhloko yokuba khona: ukwakheka kwesekethe yomshayeli kuyinkimbinkimbi, izindleko zedivayisi ziphezulu, futhi umthamo wokusebenza ukhulu kakhulu. Ayifanele inani elikhulu lamasekethe e-LED. Amafomu ahlanganisiwe ahlongozwe ngokuhlanganisa izinzuzo ezifanele zochungechunge kanye namafomu ahambisanayo. Amafomu amakhulu yilawa amabili alandelayo. (1) Uma amafomu okwakheka okuxubile kuqala, inani lezinhlelo zokusebenza ze-LED likhulu, futhi uchungechunge olulula noma uxhumano oluhambisanayo alunangqondo. Eyangaphambili idinga eyokuqala ukuthi icele i-voltage ephezulu yedrayivu (izikhathi ezingu-N ze-voltage eyodwa ye-LED VF). Ukuwisa idrayivu nge-current enkulu (izikhathi ezingu-N ze-IF yamanje ye-LED eyodwa). Lokhu kuletha ubunzima ekwakhiweni nasekukhiqizeni umshayeli, futhi kuhilela izinkinga zesakhiwo kanye nokusebenza kahle jikelele kwesekethe yokushayela. I-voltage yokusebenza yenani lama-LED ochungechungeni kanye ne-voltage yokusebenza ye-LED VF eyodwa inquma i-voltage ephumayo yamandla okushayela; Inani le-NVF linquma amandla okukhipha edrayivu. Ngakho-ke, indlela yokuxuba ngemva kokuxuba ngokuyinhloko iwukuqinisekisa ukuthi kunokwethenjelwa okuthile (iphutha le-LED entanjeni ngayinye lithinta kuphela ukukhanya okuvamile kwentambo), nokumataniswa kwesekethe yedrayivu ), Ithuthukisa ukwethembeka kunamafomu ochungechunge olula. . Isifunda sonke sinezici zesakhiwo esilula, ukuxhumana okulula, nokusebenza kahle okuphezulu. Ilungele izinhlelo zokusebenza ezinenani elikhulu lama-LED. (2) Ama-LED amaningana axutshwe nentambo yokusebenzisana kuqala bese kuba ama-skewers aqala bese anezintambo. Njengoba i-LED1-N LEDM-N ixhunywe okokuqala ukuxhuma, okuthuthukisa ukuthembeka kweqembu ngalinye lama-LED, kodwa lokhu kubalulekile. Ngenxa yalesi sizathu, ungakhetha i-voltage esebenzayo kanye neyamanje ngangokunokwenzeka njengeqembu elihambisanayo ngokumatanisa, noma ukuxazulula ukumelana okuncane kwamanje kwe-LED ngayinye. Ezinye izici nezinkinga ezikhona zaleli fomu elixubile ziyafana ne. (3) Izinhlobo ze-cross array of cross arrays ikakhulukazi ezokuthuthukisa ukuthembeka komsebenzi we-LED nokunciphisa izinga lokuhluleka. Indlela eyinhloko yokuqamba ithi: uchungechunge ngalunye lwama-LED angu-3 njengeqembu, kanye namatheminali okukhiphayo e-VA, VB, kanye ne-VC axhunywe ekuphumeni kwedrayivu yedrayivu. Uma ama-LED angu-3 ochungechunge ejwayelekile, ama-LED angu-3 akhanya ngesikhathi esifanayo; uma i-LED eyodwa noma amabili engasebenzi, ingaqinisekisa ukuthi okungenani i-LED eyodwa isebenza ngokujwayelekile. Ngale ndlela, ingathuthukisa kakhulu ukuthembeka kweqembu ngalinye lokukhanya kwe-LD, futhi ingathuthukisa ukwethembeka okuphelele kwakho konke ukukhanya kwe-LED. 2. Ukuxhumeka okuhlukene ekuxhumekeni okuhlukene kunezici zabo siqu, futhi izidingo zomshayeli zihlukile, ikakhulukazi uma i-LED eyodwa ihluleka ukwehluleka umsebenzi wesifunda, ukuthembeka okuphelele kokukhanyisa, nokuqinisekisa ukuthi i-LED iyonke ingaba ngangokunokwenzeka ngangokunokwenzeka. Kubaluleke kakhulu ukuqhubeka nekhono lomsebenzi nokunciphisa ukwehluleka kwe-LED iyonke, njll. Sekukonke, izinhlelo zokusebenza zeqembu le-LED ziyindlela ebalulekile yezinhlelo zokusebenza zangempela ze-LED. Ukuxhumana okuhlukile kwe-LED kubalulekile kuma-LED amakhulu kanye nezidingo zedizayini zamasekethe okushayela. Ngakho-ke, ekuhlanganisweni kwamasekethe angempela, ukukhetha okulungile kwendlela yokuxhuma i-LED ehambisanayo kubaluleke kakhulu ekuthuthukiseni umphumela wokukhanya kwayo, ukwethembeka komsebenzi, ukuklama nokukhiqiza umshayeli kube lula, kanye nokusebenza kahle komshini. isifunda sonke. Ukwehluleka kwemojula ekhanyayo ye-LED kanye nesixazululo: konke ukukhanya kwe-LED; Umbuzo: ukuthintana kabi; isisombululo: ukulungisa kabusha noma ukufakwa; isenzakalo: I-LED dim; Umbuzo 1. I-LED polarity iyaguqulwa; 2. I-LED yinde kakhulu ukuba ibe yinde kakhulu; 3. Ukunikezwa kwamandla okushintshayo akuhambelani nophawu lwe-voltage ye-LED; Ukukhanya; Umbuzo 1. Ukuthi isiqondiso sokufaka silungile yini; 2. Ukuthi izintambo zokuphuma kwamandla zilungile yini; 3. Intambo yamandla ixhuma futhi ihlehle; isixazululo: 1. Hlukanisa , Izintambo ezimnyama zixhunywe ezigxotsheni ezingezinhle; 3. Thola ingxenye yemigqa ephambene; xhuma kabusha; isenzakalo: Wonke ama-LED awakhanyi; Umbuzo 1. Akukho okukhipha amandla kagesi wokushintshwa kwamandla; 2. Ukuthi izintambo eziphumayo zokunikezwa kwamandla okushintshwa zilungile yini; isixazululo: 1 , Ukuhlola -kuya -kumandla okushintsha indawo yokufaka amandla; 2. Izintambo zamandla izigxobo ezinhle nezingezinhle zilungile;
