Njira yopangira mikanda ya nyali za LED

Njira yopangiraMikanda ya nyali ya LEDndi ulalo wofunikira kwambiri mumakampani opanga magetsi a LED. Mikanda ya kuwala ya LED, yomwe imadziwikanso kuti ma diode otulutsa kuwala, ndi zinthu zofunika kwambiri zomwe zimagwiritsidwa ntchito m'njira zosiyanasiyana kuyambira kuunikira kwa nyumba mpaka kuunikira kwa magalimoto ndi mafakitale. M'zaka zaposachedwa, chifukwa cha ubwino wosunga mphamvu, moyo wautali, komanso kuteteza chilengedwe cha mikanda ya nyali za LED, kufunikira kwawo kwawonjezeka kwambiri, zomwe zapangitsa kuti ukadaulo wopanga zinthu upite patsogolo komanso kutukuka.

Njira yopangira mikanda ya nyali ya LED imaphatikizapo magawo angapo, kuyambira kupanga zipangizo za semiconductor mpaka kusonkhanitsa komaliza kwa ma chips a LED. Njirayi imayamba ndi kusankha zipangizo zoyera kwambiri monga gallium, arsenic, ndi phosphorous. Zipangizozi zimaphatikizidwa muyeso wolondola kuti apange makristasi a semiconductor omwe amapanga maziko a ukadaulo wa LED.

Pambuyo poti zinthu za semiconductor zakonzedwa, zimadutsa mu njira yoyeretsa kwambiri kuti zichotse zinyalala ndikuwonjezera magwiridwe antchito ake. Njira yoyeretsayi imatsimikizira kuti mikanda ya nyali ya LED imapereka kuwala kwambiri, kusinthasintha kwa utoto, komanso kugwira ntchito bwino ikagwiritsidwa ntchito. Pambuyo poyeretsa, zinthuzo zimadulidwa m'ma wafer ang'onoang'ono pogwiritsa ntchito chodulira chapamwamba.

Gawo lotsatira pakupanga limaphatikizapo kupanga ma LED chips okha. Ma wafer amasamalidwa mosamala ndi mankhwala enaake ndipo amadutsa mu njira yotchedwa epitaxy, momwe zigawo za zinthu za semiconductor zimayikidwa pamwamba pa wafer. Kuyika kumeneku kumachitika pamalo olamulidwa pogwiritsa ntchito njira monga metal-organic chemical vapor deposition (MOCVD) kapena molecular beam epitaxy (MBE).

Pambuyo poti njira ya epitaxial yatha, wafer iyenera kudutsa njira zingapo zojambulira ndi kupukuta kuti ifotokoze kapangidwe ka LED. Njirazi zimaphatikizapo kugwiritsa ntchito njira zapamwamba zojambulira kuti apange mapangidwe ovuta pamwamba pa wafer omwe amafotokoza zigawo zosiyanasiyana za chip cha LED, monga madera a p-type ndi n-type, zigawo zogwira ntchito, ndi ma contact pads.

Ma chip a LED akapangidwa, amadutsa mu njira yosankha ndi kuyesa kuti atsimikizire kuti ali ndi khalidwe labwino komanso magwiridwe antchito. Chip imayesedwa kuti ione ngati pali magetsi, kuwala, kutentha kwa mtundu, ndi zina zofunika kuti ikwaniritse miyezo yofunikira. Ma chip olakwika amasankhidwa pamene ma chip omwe akugwira ntchito amapita ku gawo lotsatira.

Pa gawo lomaliza la kupanga, ma chips a LED amapakidwa mu mikanda yomaliza ya nyali za LED. Njira yopakira imaphatikizapo kuyika ma chips pa chimango cha lead, kuwalumikiza ku zolumikizira zamagetsi, ndikuziyika mu resin yoteteza. Paketi iyi imateteza chips ku zinthu zachilengedwe ndikuwonjezera kulimba kwake.

Pambuyo poyika, mikanda ya nyali ya LED imayesedwanso ntchito zina, kulimba, komanso kudalirika. Mayesowa amatsanzira mikhalidwe yeniyeni yogwirira ntchito kuti atsimikizire kuti mikanda ya nyali ya LED imagwira ntchito bwino komanso imatha kupirira zinthu zosiyanasiyana zachilengedwe monga kusinthasintha kwa kutentha, chinyezi, ndi kugwedezeka.

Ponseponse, njira yopangira mikanda ya nyali ya LED ndi yovuta kwambiri, imafuna makina apamwamba, kuwongolera molondola, komanso kuyang'anitsitsa bwino khalidwe. Kupita patsogolo kwa ukadaulo wa LED ndi kukonza bwino njira zopangira kwathandizira kwambiri kuti mayankho a nyali za LED azigwira ntchito moyenera, zolimba, komanso zodalirika. Ndi kafukufuku wopitilira komanso chitukuko m'munda uno, njira yopangira ikuyembekezeka kukonzedwanso, ndipo mikanda ya nyali ya LED idzakhala yothandiza komanso yotsika mtengo mtsogolo.

Ngati mukufuna kudziwa njira yopangira mikanda ya nyali za LED, takulandirani kuti mulumikizane ndi wopanga nyali za LED mumsewu wa TIANXIANG kuti akuthandizeni.Werengani zambiri.
