Ngakhale kuwala kwa UV kumakhala kowopsa kwa zamoyo zatsiku ndi tsiku, monga kutentha kwa dzuwa, kuwala kwa UV kumapereka zopindulitsa zambiri m'magawo osiyanasiyana.Monga ma LED owoneka bwino owoneka bwino, kupangidwa kwa ma LED a UV kubweretsa kumasuka kuzinthu zosiyanasiyana.
Zomwe zachitika posachedwa zaukadaulo zikukulitsa mbali za msika wa UV LED mpaka pakupanga zatsopano ndi magwiridwe antchito.Akatswiri opanga mapangidwe akuwona kuti ukadaulo watsopano wa ma LED a UV ukhoza kubweretsa phindu lalikulu, mphamvu komanso kupulumutsa malo poyerekeza ndi umisiri wina.Ukadaulo wotsatira wa UV LED uli ndi zabwino zisanu, chifukwa chake msika waukadaulo uwu ukuyembekezeka kukula ndi 31% pazaka 5 zikubwerazi.
Ntchito zosiyanasiyana
Kuwala kwa kuwala kwa ultraviolet kumakhala ndi mafunde onse kuyambira 100nm mpaka 400nm m'litali ndipo nthawi zambiri amagawidwa m'magulu atatu: UV-A (315-400 nanometers, yomwe imadziwikanso kuti long-wave ultraviolet), UV-B (280-315 nanometers, komanso yotchedwa medium wave) Ultraviolet), UV-C (100-280 nanometers, yomwe imadziwikanso kuti short-wave ultraviolet).
Zida zamano ndi zozindikiritsa zida zinali zoyamba kugwiritsa ntchito ma LED a UV, koma magwiridwe antchito, mtengo ndi kukhazikika kwabwino, komanso kuchuluka kwa moyo wazinthu, zikuchulukirachulukira kugwiritsa ntchito ma LED a UV.Kugwiritsiridwa ntchito kwa ma LED kwa UV kumaphatikizapo: masensa openya ndi zida (230-400nm), chitsimikizo cha UV, ma barcode (230-280nm), kutsekereza madzi apamtunda (240-280nm), kuzindikira ndi kuzindikira madzimadzi amthupi (250-405nm), Kusanthula kwa mapuloteni ndi kupezeka kwa mankhwala (270-300nm), chithandizo cha kuwala kwachipatala (300-320nm), polima ndi kusindikiza kwa inki (300-365nm), chinyengo (375-395nm), kutseketsa pamwamba / zodzikongoletsera (390-410nm) ).
Kukhudza chilengedwe - kuchepetsa mphamvu yogwiritsira ntchito mphamvu, kuwononga pang'ono komanso palibe zinthu zoopsa
Poyerekeza ndi matekinoloje ena, ma LED a UV ali ndi ubwino woonekera bwino wa chilengedwe.Poyerekeza ndi nyali za fulorosenti (CCFL), ma LED a UV ali ndi mphamvu yochepera 70%.Kuphatikiza apo, UV LED ndi yovomerezeka ya ROHS ndipo ilibe mercury, chinthu chovulaza chomwe chimapezeka muukadaulo wa CCFL.
Ma LED a UV ndi ang'onoang'ono kukula kwake komanso olimba kuposa ma CCFL.Chifukwa ma LED amanjenjemera komanso osagwedezeka, kusweka ndikosowa, kumachepetsa zinyalala ndi ndalama.
Ionjezerani moyo wautali
Pazaka khumi zapitazi, ma UV LED akhala akutsutsidwa pankhani ya moyo wonse.Ngakhale zili ndi zabwino zambiri, kugwiritsa ntchito kwa UV LED kwatsika kwambiri chifukwa kuwala kwa UV kumakonda kuphwanya utomoni wa LED, ndikuchepetsa moyo wa UV LED kukhala maola ochepera 5,000.
Mbadwo wotsatira wa teknoloji ya UV LED imakhala ndi "olimba" kapena "UV-resistant" epoxy encapsulation, yomwe, ngakhale ikupereka moyo wa maola 10,000, ikadali yokwanira kuti igwiritsidwe ntchito zambiri.
M'miyezi ingapo yapitayi, matekinoloje atsopano athetsa vutoli.Mwachitsanzo, phukusi lolimba la TO-46 lokhala ndi mandala agalasi linagwiritsidwa ntchito m'malo mwa lens ya epoxy, yomwe idakulitsa moyo wake wautumiki ndi kakhumi mpaka maola 50,000.Ndizovuta zazikuluzikulu zaumisiri ndi zovuta zokhudzana ndi kukhazikika kokhazikika kwa kutalika kwa mafunde atathetsedwa, ukadaulo wa UV LED wakhala njira yowoneka bwino pakuchulukira kwa ntchito.
Pkachitidwe
Ma LED a UV amaperekanso maubwino ogwirira ntchito kuposa matekinoloje ena.Ma LED a UV amapereka ngodya yaying'ono yamtengo ndi mtengo wofanana.Chifukwa cha kuchepa kwa ma LED a UV, mainjiniya ambiri opanga amafunafuna kolowera komwe kumawonjezera mphamvu yotulutsa pamalo enaake.Ndi nyali wamba za UV, mainjiniya amayenera kudalira kugwiritsa ntchito kuwala kokwanira kuti aunikire malowa kuti agwirizane komanso kuphatikizika.Kwa ma LED a UV, mawonekedwe a lens amalola mphamvu zambiri zotulutsa za UV LED kuti zikhazikike pomwe pakufunika, zomwe zimapangitsa kuti pakhale kocheperako.
Kuti zigwirizane ndi ntchitoyi, matekinoloje ena amafunikira kugwiritsa ntchito magalasi ena, kuwonjezera mtengo wowonjezera ndi zofunikira za malo.Chifukwa ma LED a UV safuna magalasi owonjezera kuti akwaniritse ngodya zolimba komanso mawonekedwe amtengo wofananira, kugwiritsa ntchito mphamvu pang'ono komanso kulimba, ma LED a UV amawononga theka loti agwiritse ntchito poyerekeza ndiukadaulo wa CCFL.
Zosankha zodzipatulira zotsika mtengo zimamanga njira ya UV LED yogwiritsira ntchito inayake kapena kugwiritsa ntchito ukadaulo wamba, zakale nthawi zambiri zimakhala zothandiza kwambiri pamitengo ndi magwiridwe antchito.Ma LED a UV amagwiritsidwa ntchito motsatizana nthawi zambiri, ndipo kusasinthika kwamitengo yamitengo ndi kulimba kwamitundu yonse ndikofunikira.Ngati wothandizira m'modzi akupereka mndandanda wonse wophatikizika wofunikira kuti agwiritse ntchito, ndalama zonse zimachepetsedwa, kuchuluka kwa ogulitsa kumachepetsedwa, ndipo gululo likhoza kuyang'aniridwa musanatumizidwe kwa wopanga makina.Mwanjira imeneyi, zocheperako zimatha kupulumutsa ndalama zauinjiniya ndi zogulira ndikupereka mayankho ogwira mtima ogwirizana ndi zofunikira pakumaliza ntchito.
Onetsetsani kuti mwapeza wothandizira amene angapereke njira zothetsera chizolowezi zotsika mtengo ndipo atha kupanga mayankho okhudzana ndi zosowa zanu.Mwachitsanzo, wogulitsa yemwe ali ndi zaka khumi pakupanga PCB, mawonekedwe owoneka bwino, kufufuza ma ray ndi kuumba azitha kupereka zosankha zingapo panjira zotsika mtengo komanso zapadera.
Pomaliza, kuwongolera kwaposachedwa kwaukadaulo mu ma LED a UV kwathetsa vuto la kukhazikika kotheratu ndikukulitsa moyo wawo mpaka maola 50,000.Chifukwa cha zabwino zambiri za ma LED a UV monga kulimba kolimba, kusakhala ndi zida zowopsa, kugwiritsa ntchito mphamvu pang'ono, kukula kochepa, magwiridwe antchito apamwamba, kupulumutsa mtengo, zosankha zotsika mtengo, ndi zina zambiri, ukadaulo ukukula kwambiri m'misika, m'mafakitale ndi angapo amagwiritsa An wokongola njira.
M'miyezi ndi zaka zikubwerazi, padzakhala kusintha kwina, makamaka mu pulogalamu yogwira ntchito.Kugwiritsa ntchito ma UV LED kudzakula mwachangu.
Vuto lalikulu lotsatira laukadaulo wa UV LED ndikuchita bwino.Pazinthu zambiri zogwiritsa ntchito mafunde ochepera 365nm, monga phototherapy yachipatala, kupha tizilombo toyambitsa matenda m'madzi ndi ma polima, mphamvu yotulutsa ma LED a UV ndi 5% -8% yokha ya mphamvu yolowera.Pamene kutalika kwa mafunde ndi 385nm ndi pamwamba, mphamvu ya UV LED imawonjezeka, komanso 15% yokha ya mphamvu zolowetsa.Pamene matekinoloje omwe akubwera akupitilira kuthana ndi zovuta, ntchito zambiri ziyamba kugwiritsa ntchito ukadaulo wa UV LED.
