Kunyangwe maranzi eUV achigona kuve nengozi kune zvipenyu muhupenyu hwemazuva ese, sekupiswa kwezuva, UV maranzi achapa akawanda anobatsira mundima dzakasiyana.Kufanana neyakajairwa mwenje inooneka ma LED, kuvandudzwa kweUV LEDs kunounza nyore kune akawanda akasiyana maapplication.
Iwo azvino budiriro tekinoroji ari kuwedzera zvikamu zvemusika weUV LED kune hurefu hutsva hwekugadzirwa kwechigadzirwa uye kuita.Madhizaini mainjiniya ari kuona kuti tekinoroji nyowani yeUV LEDs inogona kuburitsa purofiti yakakura, simba uye nzvimbo yekuchengetedza zvichienzaniswa nemamwe matekinoroji.Inotevera-chizvarwa UV LED tekinoroji ine mashanu akakosha mabhenefiti, ndosaka musika weiyi tekinoroji unotarisirwa kukura ne31% mumakore mashanu anotevera.
Zvakawanda zvekushandisa
Iyo spectrum ye ultraviolet mwenje ine ese wavelengths kubva 100nm kusvika 400nm pakureba uye inowanzo patsanurwa muzvikamu zvitatu: UV-A (315-400 nanometers, inozivikanwawo seyakareba-wave ultraviolet), UV-B (280-315 nanometers, zvakare. inozivikanwa seyepakati wave) Ultraviolet), UV-C (100-280 nanometers, inozivikanwawo seshort-wave ultraviolet).
Dental instrumentation uye zviziviso zvikumbiro zvaive zvekutanga kushandiswa kweUV LEDs, asi kuita, mutengo uye kusimba mabhenefiti, pamwe nekuwedzera hupenyu hwechigadzirwa, zviri kukurumidza kuwedzera kushandiswa kweUV LEDs.Ikozvino kushandiswa kweUV LEDs kunosanganisira: optical sensors uye zviridzwa (230-400nm), UV authentication, barcodes (230-280nm), sterilization yemvura yepamusoro (240-280nm), chiziviso uye kuona uye kuongorora mvura yemuviri (250-405nm), Kuongororwa kweprotein uye kuwanikwa kwezvinodhaka (270-300nm), kurapwa kwechiedza chekurapa (300-320nm), polymer neingi kudhinda (300-365nm), manyepo (375-395nm), sterilization yepasi / cosmetic sterilization (390-410nm) .
Kukanganisa kwezvakatipoteredza - kuderera kwesimba rekushandisa, kusarasa kushoma uye pasina zvinhu zvine ngozi
Kuenzaniswa nemamwe matekinoroji, UV ma LED ane mabhenefiti akajeka ezvakatipoteredza.Kuenzaniswa nemarambi efluorescent (CCFL), UV maLED ane 70% yakaderera simba rekushandisa.Uye zvakare, iyo UV LED ndeye ROHS certified uye haina mercury, chinhu chinokuvadza chinowanzo kuwanikwa muCCFL tekinoroji.
UV ma LED madiki muhukuru uye akasimba kupfuura maCCFL.Nekuti maUV ma LED ari kuzunguzika- uye asingade kuvhundutsa, kuputsika hakuwanzo, kunoderedza marara uye mari.
Ikuwedzera hupenyu hurefu
Mumakore gumi apfuura, UV LED dzakapikiswa maererano nehupenyu hwese.Pasinei nemabhenefiti ayo mazhinji, kushandiswa kweUV LED kwadzikira zvakanyanya nekuti danda reUV rinoda kuputsa epoxy resin yeLED, ichideredza hupenyu hweiyo UV LED kusvika pasi peawa zviuru zvishanu.
Chizvarwa chinotevera cheUV LED tekinoroji inoratidzira "yakaomeswa" kana "UV-resistant" epoxy encapsulation, iyo, nepo ichipa hupenyu hwemaawa zviuru gumi, ichiri kure nekukwana kweakawanda maapplication.
Mumwedzi mishoma yapfuura, matekinoroji matsva akagadzirisa dambudziko iri reinjiniya.Semuenzaniso, TO-46 rugged package ine girazi lens yakashandiswa kutsiva epoxy lens, iyo yakawedzera hupenyu hwesevhisi kanosvika kagumi kusvika kumaawa makumi mashanu.Iine dambudziko iri rakakura reinjiniya uye nyaya dzine chekuita nekudzikamisa kwakazara kwewavelength yakagadziriswa, UV LED tekinoroji yave sarudzo inoyevedza yehuwandu huri kukura hwekushandisa.
Performance
Ma LED eUV anopawo mabhenefiti akakosha ekuita pane mamwe matekinoroji.UV LEDs inopa diki danda angle uye yunifomu danda.Nekuda kwekushomeka kwemagetsi eUV LEDs, mainjiniya mazhinji ekugadzira ari kutsvaga danda rekona rinowedzera simba rekubuda mune imwe nzvimbo inotangwa.Nemarambi akajairwa eUV, mainjiniya anofanirwa kuvimba nekushandisa mwenje wakakwana kuvhenekera nzvimbo kuti ifanane uye compactness.Kune maUV LEDs, iyo lens chiito inobvumira yakawanda yekubuda kwesimba reUV LED kuti inyuswe painodiwa, ichibvumira kune yakaomesesa emission angle.
Kuti uenderane nekuita uku, mamwe matekinoroji angada kushandiswa kwemamwe lenzi, kuwedzera imwe mutengo uye nzvimbo inodiwa.Nekuti maUV ma LED haadi mamwe lenzi kuti awane akaomesesa danda angles uye yunifomu danda mapatani, yakaderera mashandisirwo emagetsi uye kuwedzera kusimba, UV LEDs inodhura hafu yakawandisa kushandisa zvichienzaniswa neCCFL tekinoroji.
Dzidzo dzakatsaurirwa dzinodhura dzinovaka UV LED mhinduro yeimwe application kana kushandisa yakajairwa tekinoroji, iyo yekare kazhinji ichinyanya kushanda maererano nemutengo uye kuita.Ma LED eUV anoshandiswa mune arrays muzviitiko zvakawanda, uye kuenderana kwedanda patani uye kusimba kwepakati peiyo array yakakosha.Kana mutengesi mumwe achipa iyo yese yakasanganiswa dhizaini inodiwa kune chaiyo application, iyo yakazara bhiri yezvinhu inoderedzwa, nhamba yevatengesi inoderedzwa, uye dhizaini inogona kuongororwa isati yatumirwa kune dhizaini mainjiniya.Nenzira iyi, kutengeserana kushoma kunogona kuchengetedza huinjiniya uye mutengo wekutenga uye kupa mhinduro dzinoshanda dzakagadzirirwa kupedzisa-application zvinodiwa.
Ita shuwa yekuwana mutengesi anogona kupa inodhura-inoshanda tsika mhinduro uye anogona kugadzira zvigadziriso zvakanangana nezvinodiwa zvekushandisa kwako.Semuyenzaniso, mutengesi ane makore gumi eruzivo muPCB dhizaini, tsika optics, ray tracing uye kuumba achakwanisa kupa dzakasiyana siyana sarudzo kune inodhura-inoshanda uye yakakosha mhinduro.
Mukupedzisa, ichangoburwa tekinoroji kuvandudzwa muUV LEDs yakagadzirisa dambudziko rekudzikamisa zvachose uye yakawedzera zvakanyanya hupenyu hwavo kusvika maawa makumi mashanu.Nekuda kweakawanda mabhenefiti eUV LEDs akadai sekuwedzera kusimba, pasina zvinhu zvinokuvadza, kuderera kwesimba kushandiswa, diki saizi, kuita kwepamusoro, kuchengetedza mutengo, inodhura-inoshanda kugadzirisa sarudzo, nezvimwe, tekinoroji iri kuwana traction mumisika, maindasitiri uye akawanda. inoshandisa Imwe sarudzo inoyevedza.
Mumwedzi uye makore anotevera, pachava nekumwe kuvandudzwa, kunyanya muchirongwa chekubudirira.Iko kushandiswa kweUV LEDs kuchakura nekukurumidza.
Dambudziko guru rinotevera reUV LED tekinoroji inoshanda.Kune akawanda maapplication anoshandisa wavelengths pazasi 365nm, senge yekurapa phototherapy, mvura disinfection uye polymer therapy, iyo inobuda simba reUV LEDs ingori 5% -8% yesimba rekuisa.Kana iyo wavelength iri 385nm uye pamusoro, kugona kweUV LED kunowedzera, asiwo 15% chete yesimba rekuisa.Sezvo matekinoroji ari kusimukira achiramba achigadzirisa nyaya dzekushanda, mamwe maapplication achatanga kutora UV LED tekinoroji.
