Chii chinoita kuti tembiricha yepamusoro ishande pane inotungamira kuratidza?Nekuwedzera kwekushandiswa kwe LED kuratidza skrini nhasi, kuitira kuti uwedzere zvakanakira skrini yekuratidzira, vashandisi vanofanirwa kuve nekumwe kunzwisisa kwekuchengetedza kweiyo LED skrini.Kunyangwe iri yemukati ye LED kuratidza kana yekunze ye LED kuratidza, kupisa kunogadzirwa panguva yekushanda, uye kupisa kunogadzirwa kuchaita kuti tembiricha yekuratidzira kwe LED kukwire.Asi, iwe unoziva here kuti chii chinoita kuti tembiricha ishande pane inotungamira kuratidza?Ngatitaure nezve Shenzhen LED kuratidza mugadziri Tuosheng Optoelectronics.

Mumamiriro ezvinhu akajairwa, maratidziro emukati e LED anogadzira kupisa kushoma nekuda kwekupenya kwakaderera uye anogona kuparara nega.Nekudaro, iyo yekunze yekuratidzira ye LED skrini inoburitsa kupisa kwakawanda nekuda kwekupenya kwayo kwakanyanya, uye inoda kuraswa neair conditioner kana axial fan.Sezvo kuratidzwa kwe LED kuri chigadzirwa chemagetsi, kuwedzera kwekushisa kuchakanganisa kudzikama kwemwenje we LED mabheji emwenje, nekudaro kuderedza kushanda zvakanaka kwemutyairi IC uye kupfupisa hupenyu hwesevhisi yekuratidzira kwe LED.

1. LED inoratidzira yakavhurika yedunhu kutadza: tembiricha yekushanda yekuratidzira kwe LED inodarika tembiricha yekuremerwa kwechip, iyo ichakurumidza kuderedza kupenya kwemagetsi e LED skrini, kukonzeresa kujeka kwechiedza uye kukonzera kukanganisa;iyo LED inoratidzira inonyanya kugadzirwa neyakajeka epoxy resin.Yekurongedza, kana tembiricha yekusangana ichipfuura iyo yakasimba chikamu chekuchinja tembiricha (kazhinji 125 ° C), iyo yekurongedza inoshanduka kuita rabha uye iyo coefficient yekuwedzera kwemafuta inokwira zvakanyanya, zvichikonzera kuvhurika kwedunhu kutadza kweiyo LED kuratidza.Kuwedzera tembiricha kuchakanganisa kuora kwechiedza chekuratidzira kwe LED.Hupenyu hwekuratidzira kwe LED hunoratidzwa nekudzikisira kwayo kwechiedza, ndiko kuti, kupenya kunenge kwakadzikira nekudzika nekufamba kwenguva kusvika yabuda.Kupisa kwepamusoro ndicho chikonzero chikuru chekudzikisira kwechiedza chekuratidzira kwe LED, uye inopfupisa hupenyu hwechiratidziro che LED.Kudzikiswa kwechiedza kwemhando dzakasiyana dzemaratidziro e LED kwakasiyana, kazhinji Shenzhen LED vagadziri vekuratidzira vanopa seti yeyakajairwa mwenje attenuation curves.Iko kudzikisira kweinopenya flux ye LED yemagetsi skrini inokonzerwa nekupisa kwakanyanya haidzokerike.

Iyo inopenya inopenya isati yadzoserwa mwenje kudzoreredzwa kweiyo LED kuratidzwa kunonzi "yekutanga luminous flux" ye LED yemagetsi skrini.

2. Kuwedzera kwekushisa kunoderedza kupenya kwechiedza che LED kuratidza: kutonhora kunowedzera, kusanganiswa kwema electrons nemakomba kunowedzera, gap rebhandi rinoderera, uye kufamba kwe electron kunoderera;tembiricha inowedzera, maerekitironi mune inogona tsime inoderedza maburi Mukana wemwaranzi recombination inotungamirira kune isiri-radiative recombination (kupisa), nokudaro kuderedza mukati quantum kunyatsoshanda kwe LED kuratidzwa;Kuwedzera tembiricha kunoita kuti peak yebhuruu yechip ifambe kuenda kune yakarebesa wave nzira, zvichikonzera kubuda kwewavelength yechip kusanganiswa nephosphor.Iko kusapindirana kweiyo excitation wavelength kuchaita zvakare kuti kunze kwechiedza kubviswa kweiyo chena LED kuratidza kuderera.Sikirini: Sezvo tembiricha inokwira, kuwanda kwehuwandu hwephosphor kunodzikira, huwandu hwemwenje unoburitswa hunodzikira, uye kunze kwechiedza chekubvisa mwenje wekuratidzira kwe LED kunoderera.Kuita kwe silica gel kunonyanya kukanganiswa ne ambient tembiricha.Sezvo tembiricha ichiwedzera, kushushikana kwekushisa mukati me silica gel kunowedzera, zvichiita kuti iyo refractive index yesilica gel ideredze, nekudaro ichikanganisa kushanda kwechiedza chekuratidzira kwe LED.
