Fulumirani, Kuwala kwa Nyali ya LED Kumakhala ndi Mavuto Ofala!

M'moyo watsiku ndi tsiku, zida zambiri zowunikira zomwe timagwiritsa ntchito nthawi zambiri zimapangidwa ndi mikanda ya nyali ya LED. Mikanda ya nyali ya LED ndi yomwe timatcha semiconductor emitting diode, yomwe imapangidwa ndi zida za semiconductor. Kwa mphamvu yowunikira, nambala yamagetsi imasinthidwa kukhala zida zowunikira zowunikira; mawonekedwe ake ndi kugwiritsa ntchito mphamvu zochepa, kuwala kwakukulu, mtundu wobiriwira, anti -vibration, moyo wautali, gwero lowala lozizira ndi zina. “Kuunika koŵera ”Anthu ambiri nthawi zonse amakumana ndi mavuto ena akamagwiritsa ntchito. Okonza otsatirawa adayankha mafunso odziwika bwino a mikanda ya nyali ya LED: 1. Chifukwa cha kuwala kwa mikanda ya nyali ya LED? Mikanda ya nyali ya LED ndizifukwa zotsatirazi zochepetsera mikanda yaing'ono yamphamvu yomwe timanena kuti: Zotchingira zachitsulo ndizosauka, epoxy resin yellow, chip ndi mabulaketi sizili zolimba mokwanira, kuchepa kwa chip ndi kwakukulu, ngati kuli koyera, ndi fulorosenti ufa, pali fulorosenti ufa Attenuation. 2. LED chigamba mikanda yachikasu? Chifukwa cha tsitsi lachikasu losindikiza tsitsi lachikasu makamaka limayamba chifukwa chosafanana ndi epoxy tree esters ndi machiritso othandizira, koma sizingatheke kuti nthawi yophika ya kusindikiza kwakunja ndi yaitali kwambiri. Mitundu yamankhwala 800 kapena 2339 guluu sizichitika muzochitika zotsatirazi. Tsatirani mosamalitsa momwe ntchitoyi ikuyendera kuti mupewe nthawi yayitali kapena yosakwanira kuphika. Izi zimayendetsedwa bwino. 3. Kodi nyali ya nyali ya LED ikutha? Pamene mikanda ya nyali ya LED siimakhazikika panthawi yopanga, ogwira ntchito samavala zibangili za electrostatic (ziyenera kukhala ndi zingwe), zomwe zimayambitsa chitetezo chosayenera cha electrostatic. Zowopsa zobisika. 4. Kodi mikanda ya nyali ya LED imayatsidwa? Choyamba, tiyenera kufufuza ngati mphamvu ya magetsi ikugwira ntchito bwino. Kodi chizindikirocho chikuwala? Ngati siinayatsidwe, chonde onani ngati magetsi alumikizidwa. Palibe reverse gawo, ngati pali mavuto pamwamba, chonde kulumikiza molondola. 5. Kodi mikanda ya nyali ya LED ikuyang'aniridwa? Pamene mikanda ya nyali ya LED si yamagetsi, ngati kuli koyenera kusankha pogula, wopanga akulangiza kukonzekera batire ya 3V, ndikugwiritsa ntchito batri kuti muwone kuwala komwe kudzagwiritse ntchito posankha. Nthawi zambiri, magetsi atatu a 1W angagwiritsidwe ntchito. Ma mbale opangidwa ndi aluminiyumu amayendetsedwa ndi pafupifupi 12V, ndipo sagwiritsidwa ntchito kawirikawiri mu 220V mwachindunji. Mukuwona ngati muli ndi gwero lanthawi zonse kapena magetsi oyendetsa 12V. Masiku ano mikanda ya nyali ya LED imatchulidwa kawirikawiri apa. Kodi inu mukudziwa izo? Ngati mukufunabe kudziwa zambiri za LED, chonde pitilizani kutimvera.
