Ndeapi Mamisimboti uye Hunhu hweRima Ultraviolet LED Mwenje Bead?

DUVLED marambi bead " > Duvled beads musimboti uye maitiro 1. Iyo yekuvhenekesa mwenje yemarambi akakomberedzwa mabhedhi: Iyo yekupedzisira voltage yePN knot inoumba chimwe chingave chipingamupinyi. Zi akapararira mumwe nemumwe. Nemhaka yokuti chiyero chekufambisa kwemagetsi chakakura kudarika chiyero chekufambisa kwebako, nhamba huru yekugovera magetsi ichaonekwa munzvimbo yeP, uye zvishomanana zvekutakura zvinoumbwa munzvimbo yeP. Mhando iyi yemagetsi inosanganiswa pabako pamutengo, uye simba rinobudiswa kuburikidza nenzira yesimba rechiedza. Kureva, musimboti PN bvudzi chiedza. DUVLED mwenje mutsetse mwenje sosi yekurapa michina DUV mwenje bead mutsetse mwenje sosi yekurapa michina 2. DUV mwenje bead mwenje ekuburitsa simba: inowanzonzi ekunze quantum simba rechikamu. Iyo yemukati quantum simba rechikamu ndiyo yekutanga photoelectric kutendeuka simba rechikamu pachayo. Chokutanga pane zvose, zvinosanganisira maitiro echikamu chacho pachako (sekukwanisa kuunza, kukanganisa, kusvibiswa, nezvimwewo), uye chimiro uye chimiro chechikamu chacho pachako. Zvisinei, simba rinobva muchikamu rinoreva photon inogadzirwa mukati mechikamu. Mushure mekutora, kudzokororwa, uye kuratidzwa kwechikamu chacho, nhamba yemafotoni akaitwa kunze kwechikamu anogona kuyerwa mukushanda chaiko. Nokudaro, zvinhu zvinopesvedzera zvekubvisa simba zvinosanganisira kunyura kwechikamu chacho pachayo, geometric structure yechikamu, refractive index musiyano wechikamu uye chigadziro chekuputira, uye kuparadzira maitiro echigadziro chechikamu. Pakati pavo, simba remukati quantum ndiro chibereko chechikamu chekuwedzera simba, kureva, chikamu chose chechikamu, kureva, simba rekunze kwechikamu chechikamu. Munguva yekutanga yekuvandudza chikamu, vandudza iyo yemukati quantum simba. Nzira yekutanga ndeyekuvandudza kunaka kwekristaro ye barriers uye kushandura chimiro chechivharo, kuitira kuti simba resimba rive nyore kushandura kuva simba rinopisa, uye zvino rinonatsiridza zvakananga simba rinopenya remvura yakadzika ye ultraviolet LED mwenje, uye ipapo ipapo Kuwedzera theoretical mukati quantum simba 70%, asi saka mukati quantum simba rinenge riri pedyo ne theoretical muganhu. Muchiitiko ichi, simba remukati quantum yechikamu chekuvandudza hachikwanisi kuwedzera chiedza chese chechikamu, saka kubudiswa kwekuvandudzwa kwechikamu chinofambira mberi chinova chinyorwa chekutanga chekutsvakurudza. Nzira huru ikozvino: shandura chimiro chekunze chezviyo —— TIP chimiro, shandura kushata kwepamusoro. 3. Yakadzika ultraviolet LED mwenje bead magetsi maitiro: ikozvino kudzora mudziyo, hunhu hwekutakura hwakafanana neiyo UI curve yePN knot, kudiki kuchinja kweiyo inflow voltage kuchaita shanduko huru mukumberi ikozvino (index level). Diki, uye reverse breakdown voltage. Iwe unofanirwa kusarudza nzira inokodzera kushandiswa chaiko. Sezvo tembiricha inowedzera, kumberi kwemhepo yeyakadzika ultraviolet mwenje mabheji anoderera, uye tembiricha coefficient haina kunaka. Rima ultraviolet mwenje mabheji emwenje anodya simba uye zvishoma anoshandurwa kuita simba rechiedza. Izvi ndizvo chaizvo zvatinoda. Iyo yasara kupisa simba kuwedzera knot tembiricha. Inogona kumiririrwa nemacalorie (simba) anoburitswa. 4. The optical maitiro ezvakadzama ultraviolet LED mwenje mabhero: Yakadzika UV mwenje mabhero emwenje inopa hafu -hupamhi monochrome. Sezvo gap resimba rema semiconductors richiderera sezvo tembiricha inowedzera, peak wavelength ye luminescence yayo iri pamwe netembiricha pamwe netembiricha pamwe netembiricha. Kuwedzera kuwedzera, ndiko kuti, mutsara wakatsvuka, iyo tembiricha coefficient is2 3A/. Rima ultraviolet LED pearly kupenya L inoshanduka neiyo yakanaka ikozvino. Kuwedzera ikozvino, unogona kufungidzira kupenya kwechiedza; kukwira kwe tembiricha ye ambient, kuderera kwesimba rinoumbwa nemubatanidzwa, kuderera kwesimba rinopenya, uye kudzikisa kumwe kupenya kunopenya. Deep ultraviolet rambi bead fever maitiro: diki ikozvino, tembiricha inokwira haisi pachena. Kana tembiricha yepakati yakakwira, iwo mafungu makuru eiyo yakadzika ultraviolet mabedhi anopenya anozowedzera, kupenya kunodzikira, mwenje unopenya wakaenzana unodzikira, uye kuwirirana kunova kushoma. Yakakosha dot matrix uye yakakura skrini tembiricha inosimuka ine simba rakakura pakuvimbika uye kugadzikana kweLED. Saka dhizaini yekubvisa kupisa ndiyo kiyi. Yakadzika ultraviolet LED mwenje bead hupenyu: Yenguva refu basa reyakadzika ultraviolet mwenje mabhero anotungamira mukuchembera kwakareruka, kunyanya yakakwira -simba rakadzika ultraviolet mwenje mabedhi. Pakuyera hupenyu hweyakadzika ultraviolet mwenje mabedhi, hazvina kukwana kushandisa kukuvadzwa kwegirobhu sekurasikirwa nehupenyu hweyakadzika ultraviolet LED mabedhi. Somuenzaniso, 35%, izvi zvinonzwisisika. Simba repamusoro Yakadzika UV mwenje inoburitsa diode kurongedza: Chekutanga pane zvese, funga kupisa kupisa uye kunze kwechiedza. Panyaya yekupisa kupisa, mhangura-based radiator lining inoshandiswa, uyezve yakabatana nealuminum radiator. Mbeu uye jira rinopisa zvinosungirirwa. Nzira yekupisa kupisa iri nani. Panyaya yechiedza, sarudza chip inverted hunyanzvi, uye wedzera reflex surface kuratidza mwenje kuti uparadze mwenje kubva pasi uye parutivi, kuitira kuti iwe uwane zvakawanda kunze kwechiedza.
