Njira yopanga mikanda ya nyali ya LED

Njira yopangaNyali za LEDndi ulalo wofunikira pamakampani opanga zowunikira za LED. Mikanda yowunikira ya LED, yomwe imadziwikanso kuti ma diode otulutsa kuwala, ndi zigawo zofunika zomwe zimagwiritsidwa ntchito m'njira zosiyanasiyana kuyambira pakuwunikira kunyumba kupita kumayendedwe owunikira magalimoto ndi mafakitale. M'zaka zaposachedwa, chifukwa cha ubwino wopulumutsa mphamvu, moyo wautali, ndi kuteteza chilengedwe cha mikanda ya nyali ya LED, zofuna zawo zawonjezeka kwambiri, zomwe zimapangitsa kupita patsogolo ndi kupititsa patsogolo luso la kupanga.

Kapangidwe ka mikanda ya nyali ya LED kumaphatikizapo magawo angapo, kuyambira kupanga zida za semiconductor mpaka pagulu lomaliza la tchipisi ta LED. Njirayi imayamba ndi kusankha zinthu zoyera kwambiri monga gallium, arsenic, ndi phosphorous. Zidazi zimaphatikizidwa muyeso yeniyeni kuti apange makhiristo a semiconductor omwe amapanga maziko aukadaulo wa LED.

Zinthu za semiconductor zikakonzedwa, zimadutsa njira yoyeretsera mwamphamvu kuti ichotse zonyansa ndikuwonjezera magwiridwe ake. Njira yoyeretserayi imatsimikizira kuti mikanda ya nyali ya LED imapereka kuwala kwakukulu, kusasinthasintha kwamtundu, komanso kugwira ntchito bwino ikagwiritsidwa ntchito. Pambuyo pa kuyeretsedwa, zinthuzo zimadulidwa muzipinda zing'onozing'ono pogwiritsa ntchito chodula chapamwamba.

Gawo lotsatira pakupanga ndikupanga tchipisi ta LED tokha. Zophikazo zimasamalidwa mosamala ndi mankhwala enaake ndipo zimadutsa njira yotchedwa epitaxy, momwe zigawo za semiconductor zimayikidwa pamwamba pa nsalu yopyapyala. Kuyika uku kumachitika pamalo olamulidwa pogwiritsa ntchito njira monga metal-organic chemical vapor deposition (MOCVD) kapena molecular beam epitaxy (MBE).

Ndondomeko ya epitaxial ikamalizidwa, chophikacho chiyenera kudutsa muzithunzithunzi zingapo ndikuyika masitepe kuti afotokoze mawonekedwe a LED. Njirazi zimaphatikizapo kugwiritsa ntchito njira zamakono za photolithography kupanga mapangidwe ovuta pamwamba pa nsalu yotchinga yomwe imatanthawuza zigawo zosiyanasiyana za chipangizo cha LED, monga madera a p-mtundu ndi n-mtundu, zigawo zogwira ntchito, ndi mapepala olumikizana nawo.

Pambuyo popangidwa tchipisi ta LED, amadutsa njira yosankhira ndikuyesa kuti atsimikizire mtundu wawo komanso momwe amagwirira ntchito. Chipchi chimayesedwa mawonekedwe amagetsi, kuwala, kutentha kwamtundu, ndi magawo ena kuti akwaniritse zofunikira. Tchipisi zosalongosoka zimasanjidwa pomwe tchipisi togwira ntchito timapita gawo lotsatira.

Mu gawo lomaliza la kupanga, tchipisi ta LED zimayikidwa mu mikanda yomaliza ya nyali ya LED. Kuyikako kumaphatikizapo kuyika tchipisi pa chimango chotsogolera, kuzilumikiza kuzinthu zamagetsi, ndikuziyika muzitsulo zoteteza. Kupaka uku kumateteza chip kuzinthu zachilengedwe ndikuwonjezera kulimba kwake.

Pambuyo pa kulongedza, mikanda ya nyali ya LED imayesedwa kuti igwire ntchito, kulimba, komanso kudalirika. Mayesowa amatengera momwe amagwirira ntchito kuti awonetsetse kuti mikanda ya nyale ya LED imagwira ntchito mokhazikika ndipo imatha kupirira zinthu zosiyanasiyana zachilengedwe monga kusinthasintha kwa kutentha, chinyezi, ndi kugwedezeka.

Ponseponse, kupanga mikanda ya nyali ya LED ndizovuta kwambiri, zomwe zimafuna makina apamwamba, kuwongolera bwino, komanso kuyang'anira bwino kwambiri. Kupita patsogolo kwaukadaulo wa LED komanso kukhathamiritsa kwa njira zopangira zathandizira kwambiri kuti kuyatsa kwa LED kukhale kogwiritsa ntchito mphamvu, kukhazikika, komanso kudalirika. Pofufuza mosalekeza ndi chitukuko m'gawoli, njira yopangira ikuyembekezeka kupititsidwa patsogolo, ndipo mikanda ya nyali ya LED idzakhala yothandiza komanso yotsika mtengo m'tsogolomu.

Ngati mukufuna ndondomeko yopanga mikanda LED nyale, kulandiridwa kulankhula LED msewu kuwala wopanga TIANXIANG kutiWerengani zambiri.
