Zomwe Zimagwiritsidwa Ntchito Mu UV Led Chip

Monga tonse tikudziwira, ma diode otulutsa kuwala kwa ultraviolet ndi ma semiconductors omwe amatulutsa kuwala pamlingo wina wake pomwe kuwala kumadutsa. Ma LED amadziwika ngati zida zolimba. Makampani ambiri amapanga tchipisi ta UV-based LED pamakampani, zida zamankhwala , zoletsa ndi zophera tizilombo, zida zotsimikizira zolemba, ndi zina zambiri. Ndi chifukwa cha gawo lapansi komanso zinthu zogwira ntchito. Zimapangitsa ma LED kukhala owonekera, kupezeka pamtengo wotsika, kusinthira magetsi, ndikuchepetsa mphamvu yotulutsa kuwala kuti igwiritsidwe ntchito bwino.

Buku lathunthu ili lidzakuyendetsani pazinthu zomwe zagwiritsidwa ntchito, yerekezerani mapindu, ndikufotokozerani momwe mungasankhire chipangizo choyenera cha LED.

Zida Zapakati Zogwiritsidwa Ntchito Mu ma LED a UV

Zida zazikulu zomwe zimagwiritsidwa ntchito popanga chip ultraviolet LED chip zimagawidwa m'magawo ndi zida zogwira ntchito. Zida zitatu zotsatirazi zimagwiritsidwa ntchito kwambiri popanga tchipisi.

1  Aluminium Nitride

Nkhaniyi imagwiritsa ntchito UWBG kapena Ultra-Wide Bandgap Technology. Zinthu zakuya izi zimatulutsa kuwala mumtundu wa ultraviolet, ndipo zida monga gallium nitride ndi silicon carbide zimagwiritsidwa ntchito pambali pake kuti awonjezere mphamvu zamagetsi.

Izi zimagwira ntchito pamtunda wochepera 315nm. Tchipisi za Aluminium Nitride zimathandizira pakutentha kokwanira komanso kuwongolera magetsi pazida za LED. AIN kapena aluminium nitride imalowa m'malo mwa BeO kapena beryllium oxide chifukwa ilibe zoopsa pa thanzi. Imatha kupirira kutentha kwambiri ndipo imakhala yopanda msoko pamagetsi ndi zida zina.

2  AlGaN Aloyi

Aloyiyi ndi kuphatikiza kwa Aluminium, Gallium, ndi Nayitrojeni, zomwe zimapereka kutalika kwa mafunde mpaka 400nm. Aloyi iyi yomwe imagwiritsidwa ntchito pa tchipisi ta UV LED imagwiritsa ntchito kwambiri Chithunzi cha UV-A  Zinthu za alloy izi zophatikizidwa zimakhala ndi kutalika kowoneka bwino komwe kumatulutsa kuwala kwa ultraviolet, kupangitsa kuti ikhale yoyenera pazida zamankhwala, masensa, mpweya ndi Kudwala matenda a madzi , kutsekereza, etc. Zimathandizanso kukonza magwiridwe antchito a zida.

Chifukwa cha mawonekedwe a physico-chemical a AIGaN, kupita patsogolo kwakukulu kwachitika pakukhathamiritsa kupanga chip. Ndizinthu zapamwamba kwambiri zomwe zimathandizira kuti zida za UV za LED ziziyenda bwino. Amagwiritsidwanso ntchito popanga ma eco-friendly, anzeru, komanso tchipisi chokhazikika.

3  Gawo lapansi

Zinthu zazikuluzikuluzi ndi tchipisi’ maziko, mphamvu, ndi chithandizo. Gawo lofunikira kwambiri lomwe limagwiritsidwa ntchito pa ma LED a UV ndi safiro. Ndi yowonekera, imakhala ndi kupezeka kwakukulu, ndipo imapezeka pamtengo wotsika. Kupatula izi, gawo lapansi la Sapphire lili ndi zabwino zina zambiri, monga zinthu zake zapamwamba, zokhwima zomwe zilipo, zimatha kupirira kutentha kwambiri, kuyeretsa kosavuta, komanso mphamvu zamakina amphamvu.

Kuphatikiza apo, gawo lapansi la Saphire mu tchipisi limakwaniritsa zomwe zikukula pamsika wamachiritso. Chitetezo ndi zopulumutsa mphamvu zimapangitsa gawo lapansili kukhala labwino kwambiri pakugwiritsa ntchito LED. Kutumiza kwa mafunde abwino kumathandiza kwambiri ndi magetsi oyenera komanso kutumiza kwa kuwala mu chip.

Kuyerekeza Mwamsanga Kwa Zida Zonse Zoyambira

Zida zitatuzi zimapereka maubwino osiyanasiyana zikagwiritsidwa ntchito mu tchipisi ta UV. Mafakitale, mabungwe azachipatala, okhalamo, maofesi, ndi zina zambiri, amatha kugwiritsa ntchito zida zopangidwa ndi tchipisi tapakatikati ndikupeza phindu losiyanasiyana.

Momwe Mungasankhire Chip cha UV LED pa Ntchito Yanu?

·  Kugwira Ntchita:  Posankha UV LED, onetsetsani kuti ikugwira ntchito bwino ndikutulutsa mawonekedwe a ultraviolet oyenera ntchitoyo. Kutha kukhala kuchiza kapena kutsekereza malo anu. Muyenera kuyang'ana chip’s ntchito posankha voteji yoyenera. Yang'anani kutalika ndi kukwanira kwa chipangizo cha UV LED pa ntchito inayake. Zidzathandiza kusunga khalidwe, kupititsa patsogolo ntchito, ndi kusunga mawonekedwe a LED kwa nthawi yaitali.

·  Nthaŵi: Mafunde ambiri amagwira ntchito pakati pa 200nm ndi 400nm. Sankhani chip chomwe chili ndi kutalika koyenera kuti chizigwira ntchito mwamphamvu kuti chitulutse sipekitiramu yomwe imagwira ntchito bwino ndi zida. Kutalika kothandiza kwambiri kwa ma LED kuli pakati pa 365nm ndi 395nm. Ndizotetezeka komanso zimakhala ndi ma radiation ochepa, nawonso.

·  Zokwera mtengo: Mafakitale ambiri amayendetsa bajeti ndipo amayembekezera tchipisi ta LED totsika mtengo. Chifukwa chake, sankhani chip chomwe chikugwirizana ndi ntchito yanu bwino. Mutha kugwiritsa ntchito kuchiritsa utomoni kapena inki, kutsekereza madzi ndi mpweya, kuchiritsa zipatala, kapena kufufuza zaupandu

·  Kutulutsa Kowala: Mbiri yakutulutsa kwa ma module a UV-A, UV-B, ndi UV-C iyenera kuyang'aniridwa. Muyenera kusankha ma LED a UV molingana ndi kuwala kwawo, komwe kumatha kukhala ofatsa, apakati, kapena amphamvu kwambiri. Ngati mukufuna Chip cha UV cha LED chochiritsira , mungafune china chake chokhala ndi LOP yofatsa.

Mapeto

Tchipisi za UV-LED zimachepetsa zoopsa ndikuwonetsetsa ROI pazida zanu. Mutha kupeza zinthu zapamwamba kuchokera Tianhui , wopanga wamkulu wa tchipisi. Zogulitsa zathu ndizabwino zotsekereza komanso kupha tizilombo toyambitsa matenda; mukhoza kuwagwiritsa ntchito kuchiza. Timagwiritsa ntchito ukadaulo wotsogola kupanga zatsopano ndikupanga zinthu zathu. Ngati mukuyang'ana chipangizo chabwino kwambiri cha UV LED m'derali, funsani akatswiri athu ndi nkhawa zanu. Tidzakonza mayankho athu mogwirizana ndi zosowa zanu zapadera zamalonda kapena zamankhwala.
