Isibani sokuvikela ukuqhuma kwe-LED siwuhlobo lwesibani esingaqhumi.Isimiso saso siyafana nesesibani esivikela ukuqhuma, ngaphandle kokuthi umthombo wokukhanya ungumthombo wokukhanya we-LED, obhekisela esibanini esinezinyathelo ezihlukahlukene ezithathiwe ukuvimbela indawo ezungezile yothuli kanye negesi ekushiseni.Izibani ze-LED ezingaqhumi okwamanje zingamalambu angaqhumi angawongi, asetshenziswa kumakhemikhali kaphethiloli, ezimayini zamalahle, ezitshalweni zikagesi, eziteshini zikaphethiloli nakwezinye izindawo.
Sonke siyazi ukuthi izibani ze-LED ezingaqhumi zinemiphumela emihle yokonga amandla nokukhanya okuhle.Ngakho-ke yini ethinta ukuphila kwezibani ze-LED ezingaqhumi, futhi ukunakekelwa kungaletha kanjani izinzuzo?
Izinto ezimbalwa ezithinta impilo yezibani ze-LED ezingaqhumi:
1. Izinga lentambo yisimo esiyinhloko esinquma impilo yesibani se-LED esingaqhumisi
Enqubweni yokukhiqiza ama-chips e-LED, okunye ukungcoliswa kwe-ion ukungcola, ukukhubazeka kwe-lattice nezinye izinqubo zobuchwepheshe kuzothinta impilo yabo.Ngakho-ke, ukusetshenziswa kwezintambo ze-LED eziphezulu yisimo esiyinhloko.
Isibani se-Keming esingaqhumi sithatha ubuhlalu belambu le-LED obunamandla amakhulu obulingisa i-lumen kanye nomklamo omkhulu we-chip brand.Umthombo wokukhanya we-LED oklanywe ngokukhethekile unombono ofanayo, ukudluliswa kokukhanya okuphezulu kanye ne-glare ephansi.
2. Ukwakhiwa kwesibani kuyindaba eyinhloko ethinta ukuphila kwezibani ze-LED ezingaqhumi
Ngaphezu kokuhlangana nezinye izinkomba zesibani, ukwakheka kwesibani okunengqondo kuyindaba eyinhloko yokukhipha ukushisa okukhiqizwa lapho i-LED ikhanya.Isibonelo, izibani zomthombo wokukhanya ezihlanganisiwe emakethe (i-30 W, 50 W, 100 W eyodwa), umthombo wokukhanya wale mikhiqizo kanye nengxenye yokuxhumana yesiteshi sokushisa ayibusheleli, ngenxa yalokho, eminye imikhiqizo ibangela. ukukhanya ngemva kwezinyanga ezingu-1-3 zokukhanyisa.Ukubola kungaphezu kwama-50%.Ngemva kokuba eminye imikhiqizo isebenzisa ishubhu lamandla aphansi angaba ngu-0.07 W, ngenxa yokuthi ayikho indlela enengqondo yokukhipha ukushisa, ukukhanya kwabola ngokushesha okukhulu.Le mikhiqizo emithathu engeyona imikhiqizo inokuqukethwe okuphansi kobuchwepheshe, izindleko eziphansi kanye nempilo efushane.
3. Ukunikezwa kwamandla kalambu kubaluleke kakhulu empilweni yesibani sokuvikela ukuqhuma kwe-LED
Ukuthi ukunikezwa kwamandla kwesibani kunengqondo nakho kuzothinta ukuphila kwaso.Ngenxa yokuthi i-LED iyidivayisi eqhutshwa manje, uma amandla amanje ashintsha kakhulu, noma imvamisa yama-spikes amandla iphezulu, izothinta impilo yomthombo wokukhanya we-LED.Impilo yomthombo wamandla ngokwawo incike kakhulu ekutheni idizayini yokunikezwa kwamandla inengqondo yini.Ngokwesisekelo sokuklama kokunikezwa kwamandla okunengqondo, impilo yokunikezwa kwamandla incike empilweni yezingxenye.
4. Ithonya lokushisa elizungezile empilweni yezibani ze-LED ezivimbela ukuqhuma
Ukuphila okufushane kwamanje kwezibani ze-LED ikakhulukazi ngenxa yempilo emfushane yokunikezwa kwamandla, futhi ukuphila okufushane kokunikezwa kwamandla kungenxa yokuphila okufushane kwe-electrolytic capacitor.Esinye isici senkomba yokuphila yama-electrolytic capacitor ukuthi kufanele ikhombise impilo ngaphansi kwezinga lokushisa lendawo yokusebenza ukuthi mangaki amadigri, futhi ngokuvamile icaciswa njengempilo ngaphansi kwezinga lokushisa le-ambient elingu-105 ℃.Ukwehla kwezinga lokushisa le-ambient, iba yinde impilo yesevisi ye-capacitor.Ngisho ne-electrolytic capacitor evamile enesikhathi sokuphila samahora angu-1 000 ingafinyelela emahoreni angu-64,000 endaweni yokushisa ye-45 ° C, eyanele isibani se-LED esivamile esiphila amahora angu-50,000.Wayisebenzisa.
Ukugcinwa kwansuku zonke kwezibani ze-LED ezingaqhumi:
Sithenga isibani esihle sokuvikela ukuqhuma kwe-LED singasetshenziswa iminyaka emithathu, kodwa ngokuvamile awukunaki ukugcinwa kwesibani sokuvikela ukuqhuma kwe-LED, ngakho-ke ungakwazi ukusisebenzisa iminyaka emibili kuphela, okulingana Ukusebenzisa imali eningi, sisenza kanjani isibani se-LED esingaqhumi Ukuphila isikhathi eside kuyisihluthulelo, ake sikhulume kafushane ngezinto ezimbalwa ezingezansi:
1. Hlanza njalo uthuli nezinye izinsalela ezindlini zezibani (uma zingahlanzwa isikhathi eside, uthuli lunamathela esibanini ukuze luvimbele ukushisa okukhishwa isibani, okuholela ekushiseni okungaqediwe. Lokhu kuwukuqinisekisa ukuthi isibani se-LED esingaqhumisi Umphumela omuhle wokushisa ukushisa), ukuchithwa kahle kokushisa kuyisici esibalulekile sokwelula impilo ye-LED.
2. Ukulungiswa kanye nokucisha kwezibani.Kunconywa ukuthi izibani zingasebenzi ngokungaphazamiseki amahora angu-24, ngoba izinga lokushisa lezibani lizokhuphuka kancane kancane phakathi nomsebenzi ongaphazamiseki.Uma izinga lokushisa liphezulu, kuba nomthelela omkhulu empilweni yesibani.Uma izinga lokushisa liphakeme, impilo yesibani iba mfushane..
3. Ikhava yokudlulisa ukukhanya njalo ihlanza uthuli nezinye izibi ukuze kuqinisekiswe umphumela wokudlulisa ukukhanya
4. Hlola njalo i-voltage yesifunda.Uma i-voltage ingazinzile, isifunda kufanele sigcinwe futhi silungiswe.
5. Izinga lokushisa elizungezile lamalambu e-LED angaqhumi akumele libe ngaphezu kwamadigri angu-60, futhi impilo yesevisi ingase incishwe ngokuqondile ngo-2/3 uma ingaphezulu kuka-60 degrees.
6. Izibani kufanele zivulwe njalo ngesikhathi sokusetshenziswa okujwayelekile.
