Nekuda kwekushomeka kwesimba repasi rose uye kusvibiswa kwezvakatipoteredza, LED inoratidzira ine nzvimbo yakakura yekushandisa nekuda kwehunhu hwayo hwekuchengetedza simba uye kuchengetedza kwezvakatipoteredza. Mumunda wekuvhenekera, kushandiswa kweZvigadzirwa zve LED zvinopenyairi kukwezva pfungwa dzenyika. Kazhinji kutaura, kugadzikana uye kunaka kwemwenje ye LED kune hukama nekupisa kwekupisa kwemuviri wemwenje pachayo. Parizvino, kupisa kwekupisa kwekupenya kwakakwirira kwemarambi e-LED mumusika kunowanzotora kupisa kwechisikigo, uye mhedzisiro yacho haina kunaka.Mwenje we LEDyakagadzirwa ne LED mwenje sosi inoumbwa ne LED, kupisa disipation chimiro, mutyairi uye lens. Nokudaro, kupisa kupisa kunokoshawo chikamu. Kana LED isingakwanise kupisa zvakanaka, hupenyu hwayo hwesevhisi huchakanganiswawo.

Heat management ndiro dambudziko guru mukushandiswa kwekupenya kwepamusoro LED

Nekuti iyo p-type doping yeboka III nitrides inoganhurwa nekunyungudika kweMg vanogamuchira uye nepamusoro pekutanga simba remakomba, kupisa kunonyanya nyore kugadzirwa munzvimbo yep-mhando, uye kupisa uku kunofanirwa kubviswa pane singi yekupisa. kuburikidza nechimiro chose; Nzira dzekupisa kupisa dze LED midziyo inonyanya kupisa conduction uye kupisa convection; Iyo yakanyanya kuderera yekupisa yekupisa yesafire substrate zvinhu inotungamira kukuwedzera kwekupisa kwechigadzirwa, zvichikonzera kudzika kwekudziya kwega, iyo ine kukanganisa kunoparadza pakuita uye kuvimbika kwechishandiso.

Mhedzisiro yekupisa pakupenya kwakanyanya kwe LED

Kupisa kunoiswa mudiki chip, uye tembiricha yechip inowedzera, zvichikonzera kugovera kusiri kwakafanana kwekushushikana kwekupisa uye kuderera kweiyo chip luminous performance uye phosphor lasing performance; Kana tembiricha ikadarika imwe kukosha, mwero wekutadza kwechigadzirwa unowedzera zvakanyanya. Statistical data inoratidza kuti kuvimbika kunodzikira ne10% yega yega 2 ℃ kukwira kwechikamu chetembiricha. Kana ma LED akawanda akarongedzerwa zvakanyanya kuti aumbe chena mwenje system, dambudziko rekupisa kupisa rinonyanya kuoma. Kugadzirisa dambudziko rekutonga kwekupisa kwave kudikanwa kwekushandiswa kwekupenya kwakanyanya kwe LED.

Hukama pakati pehukuru hwechip uye kupisa kupisa

Nzira yakananga yekuvandudza kupenya kwesimba re LED kuratidza skrini ndeyekuwedzera simba rekupinza, uye kuitira kudzivirira kuzara kweiyo inoshanda layer, saizi yepn junction inofanira kuwedzerwa zvinoenderana; Kuwedzera simba rekuisa kunozowedzera kuwedzera tembiricha yekusangana uye kuderedza quantum kunyatsoshanda. Iko kunatsiridza kwesimba rimwe chete transistor kunoenderana nekugona kwechishandiso kuendesa kunze kupisa kubva kune pn junction. Pasi pemamiriro ekuchengetedza iripo chip zvinhu, chimiro, kurongedza maitiro, ikozvino density pane chip uye yakaenzana kupisa dissipation, kuwedzera chip size chete kuchawedzera tembiricha yekusangana.
