Iyo LED yekushongedza mwenje muviri haiburitse ultraviolet rays

LED single chubhu simba 0.03 ~ 0.06 watts, uchishandisa DC drive, imwe chubhu yekutyaira voltage 1.5 ~ 3.5 volts, ikozvino 15 ~ 18 mA, kukurumidza kupindura, inogona kushanda pakakwirira frequency. Pasi pemamiriro ekuvhenekera kwakafanana kwemwenje yekushongedza ye LED, simba rekushandisa inosvika zviuru gumi zveiyo incandescent bulbs, uye imwe hafu yeiyo fluorescent chubhu. Inofungidzirwa muJapan kuti kana ma LED ane kaviri kupenya kwemagetsi anoshandiswa kutsiva hafu yemabharubhu eJapan. Incandescent uye fluorescent mwenje. Iyo yakaenzana ne6 mabhiriyoni emarita emafuta asina kuchena anogona kuchengetwa gore negore. Panyaya yemarambi ebhiriji, rambi refluorescent rine mhedzisiro yakafanana rinopfuura makumi mana watts, nepo simba re LED yega yega richingova 8 watts, uye rinogona kuve neruvara.

Iyo yezororo LED yekushongedza marambi emutambo wekushongedza mwenje purojekiti inoshandisa magetsi emagetsi mwenje mwenje kuburitsa mwenje, uye mafilaments ane zvazvakaipira senge kupisa nyore, kupisa kupisa, uye kudzikamisa mwenje. Mwenje we LED idiki muhukuru uye uremu huremu, wakaputirwa ne epoxy resin, unogona kutsungirira yakakwirira-yakasimba mechanical shock uye vibration, uye haisi nyore kutyora. Avhareji yehupenyu i100,000 maawa. Hupenyu hwesevhisi yemutambo we LED wekushongedza mwenje muviri unogona kusvika makore 5-10, izvo zvinogona kuderedza zvakanyanya mutengo wekugadzirisa mwenje uye kudzivirira marwadzo ekugara achitsiviwa mwenje.

Muviri wehoridhe ye LED yekushongedza mwenje haiburitse ultraviolet rays, saka hapazove neumhutu huzhinji hwakatenderedza mwenje sosi semarambi echinyakare. Marambi echinyakare anovhenekerwa nemagetsi akakwira anoburitswa neanogadzirisa, uye haagone kubatidzwa kana voltage yadzikiswa. Muviri wemwenje wekushongedza wezororo unogona kuvhenekerwa mukati mehumwe huwandu hwemagetsi, uye kupenya kunogonawo kugadziriswa.

Iwo ma LED machipi ezororo e LED ekushongedza marambi anozochembera panguva yekuvhenekesa, uye ipapo mwenje unoora. Kazhinji, mushure menguva yekushandiswa, mwenje ichave yakasviba zvishoma pane yekutanga, uye kuderera kwechiedza chekuora kunogona kuvimbisa hupenyu hurefu. Pane yakakwirira junction tembiricha, kuora kwechiedza kwe LED kunozowedzera zvishoma nezvishoma sezvo tembiricha inokwira. Kamwe tembiricha yemukati ye LED ichipfuura tembiricha yejunction, kuora kwechiedza kuchawedzera mumutsara wakatwasuka.

Kubwinya kwakanyanya kunoderedza kugadzirwa kwekupisa, uye kudzikisira chizvarwa chekupisa kunogona kuderedza kuora kwechiedza, uye tembiricha yepamusoro yejunction inoderedza zvinodikanwa zvema radiator. Kusarudza yepamusoro-giredhi machipisi ndiyo yakanakisa mutambo we LED yekushongedza mwenje muviri. Zvisinei, marambi ane American CREE chips haigoni kutengwa pane imwe pfuma, nokuti inodhura zvikuru, uye kusiyana pakati pemachipisi ehukuru hwakafanana inenge 10-100 nguva, uye musiyano pakati pezvigadzirwa zvakapedzwa zvakatonyanya kukura.
