Sankhani Maluso a Chip Chip Light Light Source

Mtengo wa ma modules a LED light source wapangidwa posachedwa, ndipo ma LED akhala akudziwika kuti ndi obiriwira komanso oyeretsa zachilengedwe. Magwero a kuwala kwa LED amakhala ndi moyo wautali wautumiki, kupulumutsa mphamvu ndi kupulumutsa mphamvu, kugwiritsa ntchito kosavuta komanso kosavuta, komanso ndalama zotsika mtengo. Chotero. Kumayambiriro kwa chaka cha 2008, mipando yapadziko lonse yowunikira nyumba padziko lonse inali pafupifupi 50 biliyoni. Ukadaulo wa magwero a kuwala kwa LED wakula kwambiri, ndipo kuwala kwa matailosi aliwonse kwakula mwachangu, ndikupangitsa kuti mtengowo uchepetse chaka ndi chaka. Msika waukulu komanso kufunikira kokhazikika kwa nyali zobiriwira za LED kudzakhala msika wapamwamba kwambiri wa tsunami pamsika wophatikizika wozungulira pambuyo pa VCD, DVD, mafoni am'manja, ndi MP3! Kuchita bwino kwambiri kwamphamvu zopulumutsa mphamvu, moyo wautali, komanso kuteteza chilengedwe kwa nyali za LED ndizodziwika bwino. 1. LED mkulu mphamvu -kupulumutsa: DC dalaivala, kopitilira muyeso -otsika mphamvu (chubu limodzi 0.03 1W) Kutembenuka kwa magetsi a magetsi kuli pafupi ndi 100, kuyatsa komweko kumaposa 80% kupulumutsa mphamvu kuposa magwero achikhalidwe. 2. Moyo wautali wa LED: Gwero la kuwala kwa LED limatchedwa kuwala kwa moyo wautali. Zowunikira zozizira zolimba, ma epoxy resin ma CD, ndipo palibe ziwalo zotayirira m'thupi la nyali. Palibe zoperewera monga kuyatsa kwa filament, kuyatsa kutentha, ndi kuwala kofulumira. Zoposa zambiri. 3. Kuteteza Kwachilengedwe kwa LED: LED ndi gwero lobiriwira, ndipo zoteteza zachilengedwe ndizabwinoko. Palibe kuwala kwa ultraviolet ndi infrared mu sipekitiramu, zopatsa mphamvu zochepa komanso kung'anima kwaulere, palibe ma radiation, komanso zinyalala zitha kubwezeredwa. Palibe kuipitsa popanda mercury, magwero ozizira ozizira, omwe angakhudzidwe bwino. Ndi ya mmene wobiriwira gwero kuyatsa. Makhalidwe a ntchito ya module yowunikira ya LED ndi otsika kwambiri mu VF voteji ya magwero a kuwala kwa LED. Nthaŵi zambiri, ndi 2.75 3.8V. Chifukwa chake, mphamvu yotulutsa ya LED drive IC ndi VFXN kapena VFX1, ndipo IF imayenda mosalekeza pa 15 1,400ma. Gwero la kuwala kwa LED lomwe limagwiritsidwa ntchito ndi nyali za LED lili ndi mitundu iwiri: mphamvu yaying'ono (IF ndi 15 20mA) ndi high -power (ngati wamkulu kuposa 200mA). Mphamvu yaying'ono ya LED imagwiritsidwa ntchito ngati nyali zadzuwa za LED, nyali zokongoletsa, ndi nyali za grille. High-power LED imagwiritsidwa ntchito pakuwunikira mabanja, zowunikira, zowunikira pansi, nyali zapakhoma, zowunikira mumsewu, zowunikira, zowunikira zamagalimoto, ndi zina zambiri. Gwero la kuwala kwa LED ndi chipangizo chotsika kwambiri komanso chachikulu choyendetsedwa ndipano. Mphamvu zake zowala zimatsimikiziridwa ndi zomwe zikuyenda kudzera mu LED. Zamakono zidzachititsa kuti kuwala kwa LED kuwonongeke, ndipo zamakono ndizochepa kwambiri zidzakhudza mphamvu yowala ya LED. Choncho, dalaivala wa LED ayenera kupereka magetsi nthawi zonse kuti atsimikizire chitetezo cha ma LED apamwamba kwambiri, ndipo nthawi yomweyo akwaniritse kuyatsa koyenera. M'munda wa kuyatsa kwa LED, kuti muwonetse mawonekedwe a kupulumutsa mphamvu kwa kuwala kwa LED ndi moyo wautali, ndikofunikira kusankha bwino dalaivala wa LED IC. Popanda machesi abwino a IC, ubwino wa kuyatsa kwa LED sungathe kuwonetsedwa. LED -mbali kuwala gwero LED jekeseni akamaumba gawo Mzere kuwala LED madzi ulimi wothirira guluu gawo Hongyan kanyumba atatu - mmodzi kanyumba LED kuwala gwero gawo zofunika pa otsika -voltage galimoto tchipisi ayenera anakumana ndi mwadzina athandizira voteji osiyanasiyana Chip galimoto, DC 8 40V, kuti ikwaniritse zosowa zambiri zogwiritsira ntchito. Kutha kukana kukakamiza ndikwambiri kuposa 45V. Kulowetsako ndi AC 12V kapena 24V, voteji yosavuta yosinthira mlatho imasinthasintha ndi magetsi a gridi, makamaka mphamvu ikakhala yayikulu, magetsi a DC amakhala okwera. Ngati IC yoyendetsa ilibe ma voliyumu ambiri olowera, nthawi zambiri imalowetsedwa mphamvu ya gridi yamagetsi ikukwera, potero kuwotcha gwero la kuwala kwa LED. 2. Kutulutsa kwadzidzidzi kwa chipangizo choyendetsa kumafuna kupitilira 1.2 1.5A. Monga gwero la kuwala kwa LED pakuwunikira, mphamvu yamagetsi ya 1W magetsi a LED ndi 350mA, ndipo mphamvu yogwiritsira ntchito mphamvu ya magetsi a 3W ndi 700mA. Magwero owunikira a LED okhala ndi mphamvu yayikulu amafuna mphamvu yayikulu, kotero dalaivala wa IC wosankhidwa ndi zowunikira za LED ayenera kukhala ndi zotulutsa zokwanira pano. Popanga zinthu, dalaivala IC ntchito iyenera kugwiritsidwa ntchito pa 70-90% ya malo abwino kwambiri ogwirira ntchito a 70-90% a zotulutsa zonse. Ma IC oyendetsa pogwiritsa ntchito katundu wathunthu pakali pano samatayika mu malo ang'onoang'ono a nyali, zomwe zingayambitse kutopa komanso kulephera koyambirira kwa nyali. 3. Kutulutsa kwaposachedwa kwa chipangizo choyendetsa kuyenera kukhala kosasintha, kuti LED iwale mokhazikika popanda kuwunikira. Gulu lomwelo la tchipisi tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono tating'ono ting'onoting'ono. mizere. Kwa chip china cha discrete chokhala ndi kuwululidwa kwina kwa zomwe zikutuluka pakali pano, ndikofunikira kusankha zosankha kutsogolo kwa fakitale kapena kuziyika mumzere wopanga, sinthani kukana kwa kukana kwapano pa PCB board, kuti nyali za LED - bolodi lokhazikika lomwe limapangidwa ndi bolodi la PCB Kuwala ndi kuwala kwa gwero la kuwala kumagwirizana kuti zikhalebe zogwirizana ndi mapeto.
