Kana iyo LED ichishanda, anotevera mamiriro anogona kuita kuti tembiricha yejunction ikwire kune madhigirii akasiyana.

1, Zvave zvichiratidzwa kuti kudzikisira kwekupenya kwakanaka ndicho chikonzero chikuru chekusimuka kweLED junctiontembiricha. Parizvino, kukura kwezvinhu zvepamberi uye maitiro ekugadzira echikamu anogona kushandura mazhinji ekuisa simba remagetsi eLED muchiedzasimba remwaranzi. Nekudaro, nekuti ma LED chip zvinhu zvine akakura akakura refractive coefficients kupfuura akatenderedza midhiya, chikamu chikuru chephotons (> 90%) inogadzirwa mukati meiyo chip haigone kupfachukira iyo interface, uye kuratidzwa kwakazara kunogadzirwa pakati peiyo chip uye media media, Iyo. inodzokera mukati meiyo chip uye inopedzisira yatorwa neiyo chip zvinhu kana substrate kuburikidza neakawanda emukati maratidziro, uye inova inopisa muchimiro chelattice vibration, ichisimudzira tembiricha yekusangana kuti ikwire.

2, Sezvo iyo PN junction isingagone kuve yakanyanya kukwana, kushanda kwejekiseni kwechinhu hakusvike 100%, kureva kuti, mukuwedzera kune yekuchaja (gomba) yakabaiwa munzvimbo yeN munzvimbo yeP, nzvimbo yeN ichabayawo. kuchaja (electron) munzvimbo yeP apo LED iri kushanda. Kazhinji, iyo yekupedzisira mhando yejekiseni yekuchaja haiburitse optoelectric athari, asi inopedzwa nenzira yekudziya. Kunyangwe chikamu chinobatsira chejekiseni chekuchaja chikasave chakareruka, chimwe chinozopedzisira chave kupisa kana chasanganiswa netsvina kana kuremara munzvimbo yekusangana.

3, Iyo yakaipa electrode chimiro chechinhu, zvimisikidzo zvehwindo layer substrate kana nzvimbo yekusangana, uye conductive sirivheri glue zvese zvine humwe hunhu hwekupikisa. Izvi zvinopikisa zvakarongedzerwa kune mumwe nemumwe kuti zvigadzire kutevedzana kwekupokana kweLED element. Apo ikozvino inoyerera kuburikidza nePN junction, inoyererawo kuburikidza nevanopikisa izvi, zvichiita kuti Joule inopisa, iyo inotungamira kukwira kwekushisa kwechiputi kana kupisa kwejunction.
