"LED junction tembiricha" haina kujaira kune vanhu vazhinji, asi kunyangwe kune vanhu vari muindasitiri ye LED! Zvino ngatitsanangure zvizere. Apo iyoLED inoshanda, zvinotevera zvinogona kusimudzira tembiricha yejunction kuti ikwire mumadhigirii akasiyana.

1, Zvakaratidzwa nemaitiro mazhinji kuti kudzikisira kwekubuda kwechiedza ndicho chikonzero chikuru chekuwedzera kwekushisa kwejunction ye LED. Parizvino, kukura kwezvinhu zvepamberi uye tekinoroji yekugadzira tekinoroji inogona kushandura yakawanda yemagetsi ekuisa simba reinotungamirwa kuita mwenje radiation simba. Nekudaro, nekuda kweiyo yakakura kwazvo refractive index yeChipo che LEDzvinhu zvichienzaniswa neyakatenderedza svikiro, akawanda mafotoni (> 90%) anogadzirwa muchip haagone kufashukira mushe, uye ratidziro yakazara inoitika pakusangana pakati pechip nepakati, Inodzokera mukati meiyo chip uye inopedzisira yanyudzwa. neiyo chip zvinhu kana substrate kuburikidza neakawanda emukati maratidziro, uye inova kupisa nenzira yelattice vibration, iyo inosimudzira kukwira kwejoni tembiricha.

2, Nekuti pn junction haigone kuve yakanyanya kukwana, kushanda kwejekiseni kwechinhu hakusvike 100%, ndiko kuti, kana iyo LED ichishanda, mukuwedzera kune jekiseni (gomba) munzvimbo n munzvimbo yeP, iyo n. nzvimbo inozopinzawo charge (electron) munzvimbo yeP. Kazhinji, jekiseni rekuchaja rerudzi rwekupedzisira hariburitse optoelectric athari, asi inopedzwa nenzira yekudziya. Kunyangwe chikamu chinobatsira chejekiseni chakajairwa hachizoreruke zvese, uye zvimwe zvinozopedzisira zvave kupisa kana zvasanganiswa netsvina kana kuremara munharaunda yekusangana.

3, Iyo yakashata electrode chimiro chechinhu, zvinhu zvehwindo layer substrate kana nzvimbo yekubatanidza uye conductive sirivheri glue zvese zvine kumwe kupikisa kukosha. Izvi zvinopikisa zvakarongedzerwa pamwe chete kuti zvigadzire kutevedzana kwekupokana kweLED element. Apo ikozvino inoyerera kuburikidza ne pn junction, inoyererawo kuburikidza neaya anopikisa, zvichiita kuti Joule inopisa, zvichiita kuti kuwedzera kwekushisa kwe chip kana kupisa kwejunction.

Chokwadi, nekufambira mberi kwesainzi neruzivo rwokugadzira zvinhu, chikonzero chikuru nei tisinganzwisisi zviri pamusoro apa chimwe nechimwe ndechokuti hatigoni kuzvinzwisisa chimwe nechimwe munguva yemberi. Chokwadi, hatigoni kuzvinzwisisa mumwe nomumwe nokufambira mberi kwesayenzi noruzivo rwokugadzira zvinhu!
