Ingabe Ubuhlalu Belambu Le-LED Elinamandla Aphezulu Likwehlisa Kanjani Ukushisa Likhuphuka Futhi Ligwema I-Anti -corrosion?

Kuyinto engaziwa ukulahlekelwa amalambu e-LED, kodwa ingase ingazi okuningi mayelana nemikhiqizo yesibani se-LED ephezulu. Ngesikhathi senqubo yokufakwa kwemikhiqizo yezibani zamandla aphezulu we-LED namadivayisi, ukuchithwa kokushisa, ukuvikelwa kwe-electrostatic, kanye nokushisela kunomthelela omkhulu ezicini zabo. Kudingeka kubangele ukuthi Naka ukusetshenziswa kwamakhasimende. Ake ngikwethule kafushane ukuthi unganciphisa kanjani izinga lokushisa kanye nendlela yokugwema ukugqwala kubuhlalu besibani se-LED enamandla amakhulu. 1. Unganciphisa kanjani izinga lokushisa le-high-power LED ubuhlalu besibani. Njengamanje, izindlela zokukhipha ukushisa kwezibani ze-LED ikakhulukazi zifaka i-convection yemvelo kanye nokuchithwa kokushisa, abalandeli abafakiwe baphoqelelwe ukuchithwa kokushisa, ipayipi yokushisa kanye nokushisa kwepayipi yokushisa kwesifunda, njll. 1. Ukuhlukaniswa kwamandla kagesi kusuka kumzimba wokukhanya kuhlukaniswa nomthombo wamandla ngokwawo, okwandisa umthombo wokushisa wesibani se-LED. Ngesikhathi esifanayo, ukuhlanganiswa kwamandla kagesi kanye nezibani kwenza izibani ze-LED zishise ngokulinganayo zizonke. Lezi zici zizodala ukukhathala kanye nokwehluleka kwangaphambi kwesikhathi kwesibani, okuzothinta ubude baso bokuphila. 2. Ukukhethwa kokukhethwa kwamamojula we-LED wekhwalithi ephezulu ye-LED nakho kudlala indima ebalulekile ekwehliseni izinga lokushisa. Khetha ubuhlalu besibani se-LED obumbozwe i-coefficient yokushisa okuphezulu nezinto ezingaguquguquki, ezingathuthukisa ukusakazeka kokushisa kwangaphakathi. I-substrate yensimbi ene-heat-conducting ephezulu kanye nokukhishwa kokushisa okuphezulu isetshenziswa njengepuleti eliwumgogodla wokukhanya ukwenza ukusatshalaliswa kwezinga lokushisa ngokulinganayo, ukuze umphumela wokukhipha ukushisa ukhuliswe. 3. Ukwandisa indawo yokukhipha ukushisa kwe-aluminium substrate kanye nesixhumi esibonakalayo sethebhulethi yokukhipha ukushisa kulula ukuba nezikhala, futhi i-coefficient yokushisa yomoya incane kakhulu, kuphela mayelana ne-0.03W/m ·K, ngakho-ke ingasetshenziswa endaweni yokuxhumana ene-conductivity ephezulu ye-thermal endaweni yokuxhumana ukuze kwandiswe indawo yokuxhumana yangempela. Ngesikhathi esifanayo, ukwandisa indawo yokushisa ukushisa kwe-heat sink futhi uguqule isakhiwo se-heat sink ukuze kube lula ukuchithwa kokushisa. Okwesibili, indlela yokugwema ukugqwala kobuhlalu belambu le-LED lamandla aphezulu: ubuhlalu besibani se-LED obunamandla angaqhubeka nokusebenza ngaphansi kwezimo eziningi ezihlukene. Kodwa-ke, uma ubuhlalu besibani se-LED bugqwalile futhi ubuhlalu besibani se-LED busabela ngamakhemikhali ngendawo ezungezile, ukusebenza kobuhlalu besibani se-LED kuzoncipha. Ukugwema ukugqwala kobuhlalu besibani se-LED kuyingxenye ebalulekile yokuthuthukisa ukuthembeka kobuhlalu besibani se-LED. Ukuthembeka kobuhlalu besibani se-LED kungenye yezimpawu ezibalulekile ezisetshenziselwa ukulinganisa impilo yobuhlalu besibani se-LED. Ukuhlaziywa kwe-photoelectric ye-Tianhui yezizathu zokuthi kungani ubuhlalu besibani se-LED bugqwalile futhi bunikezwe indlela yokugwema ukugqwala kobuhlalu besibani se-LED. —— Gwema ubuhlalu besibani se-LED eduze kwezinto eziyingozi, futhi unciphise ngempumelelo izinga lokuhlushwa kanye nezinga lokushisa elizungezile lezinto eziyingozi. Ukuze ugweme ukugqwala kobuhlalu belambu le-LED, gwema ukuthintana nemibuthano emise okwe-O (O -RING), padding, irabha ephilayo, amaphedi amagwebu, irabha yophawu, i-sulphur equkethe umzimba onwebekayo, amaphedi ashaqisayo nezinye izinto eziyingozi. Ngisho nenani elincane lezinto eziyingozi lingabangela ubuhlalu besibani se-LED ukuba bugle. Ngisho noma ubuhlalu besibani se-LED buthintana kuphela negesi egqwalayo phakathi nenqubo yokucubungula, njengemishini ekulayini wokukhiqiza ingase ibe nemiphumela emibi. Kulezi zimo, ungakwazi ukubona ukuthi ingxenye yobuhlalu besibani se-LED yonakele yini ngaphambi kwezilungiselelo zangempela zesistimu. Uma ubuhlalu besibani se-LED bungakwazi ukugwema ngokuphelele lezi zinto eziyingozi, ubuhlalu besibani se-LED obunokumelana nokugqwala okuphezulu kufanele kusetshenziswe. Okungenhla kumayelana “Ingabe ubuhlalu besibani se-LED enamandla amakhulu kunciphisa kanjani izinga lokushisa futhi kugweme ukubola? ”Ukuze uthole isingeniso esifushane, sicela unake leli sayithi uma ulidinga.
