Mgbe LED na-arụ ọrụ, ọnọdụ ndị na-esonụ nwere ike ime ka nkwụsịtụ okpomọkụ na-ebili na ogo dị iche iche.

1. E gosiputara na mmachi nke luminous arụmọrụ bụ isi ihe kpatara ịrị elu nkeNjikọ LEDokpomọkụ. Ka ọ dị ugbu a, uto ihe dị elu na usoro nrụpụta akụrụngwa nwere ike ịtụgharị ọtụtụ ume ọkụ eletrik nkeLED n'ime ọkụike radieshon. Agbanyeghị, n'ihi na ihe mgbawa LED nwere ọnụọgụ refractive ka ukwuu karịa mgbasa ozi gbara ya gburugburu, akụkụ buru ibu nke photons (> 90%) emebere n'ime mgbawa ahụ enweghị ike ijupụta ngwa ngwa na interface ahụ, a na-emepụta echiche zuru oke n'etiti mgbawa na interface mgbasa ozi, Ọ. laghachi n'ime nke mgbawa na-emesị etinye obi gị dum site mgbawa ihe ma ọ bụ mkpụrụ site multiple esịtidem reflections, na-aghọ na-ekpo ọkụ n'ụdị lattice vibration, na-akwalite nkwụsịtụ okpomọkụ ebili.

2, Ebe ọ bụ na PN junction enweghị ike ịbụ oke zuru oke, injection arụmọrụ nke mmewere agaghị eru 100%, ya bụ, na mgbakwunye na ụgwọ (oghere) igba n'ime N ebe na P n'ógbè ahụ, n'ógbè ahụ ga-agbanye. chaja (electron) n'ime mpaghara P mgbe LED na-arụ ọrụ. N'ozuzu, ụdị ịgba ụgwọ nke ikpeazụ agaghị emepụta mmetụta optoelectric, kama a ga-eri ya n'ụdị kpo oku. Ọbụlagodi na akụkụ bara uru nke ụgwọ ịgbanye anaghị aghọ ọkụ, ụfọdụ ga-emecha bụrụ okpomoku mgbe ejikọtara ya na adịghị ọcha ma ọ bụ ntụpọ na mpaghara njikọ.

3, The ọjọọ electrode Ọdịdị nke mmewere, ihe nke window oyi akwa mkpụrụ ma ọ bụ junction ebe, na conductive ọlaọcha gluu niile nwere ụfọdụ iguzogide ụkpụrụ. Ndị a resistances na-stacked megide ibe ha na-etolite usoro nguzogide nkeIgwe ọkụ LED. Mgbe ihe dị ugbu a na-agafe na nkwụsị PN, ọ ga-esikwa na ndị na-eguzogide ndị a, na-ebute okpomọkụ Joule, nke ga-eduga na ịrị elu nke mgbawa okpomọkụ ma ọ bụ nkwụsịtụ okpomọkụ.
