9. Tambayoyin da ake yawan yi (Bisa Ma'auni na Fasaha)

Q: Menene bambanci tsakanin tsayin zango na kololuwa da matsakaicin tsayin zango?

A: Tsayin zango na kololuwa (λ_P) shine tsayin zango guda ɗaya wanda bakan fitarwa ya fi ƙarfi (464 nm na yau da kullun). Matsakaicin tsayin zango (λ_d) ƙima ce da aka samo daga ma'auni na launi akan zanen CIE; yana wakiltar tsayin zango guda ɗaya na haske mai launi ɗaya wanda zai dace da launin da ake gani na LED (kewayon 460-480 nm). Matsakaicin tsayin zango ya fi dacewa don ƙayyadaddun launi.

Q: Me yasa akwai abin ragewa don halin gaba sama da 45°C?

A: Abin ragewa (0.62 mA/°C) yana da mahimmanci don iyakance zafin haɗuwa na ciki na LED. Yayin da yanayin yanayi ke tashi, ikon na'urar na watsar da zafi yana raguwa. Rage halin yanzu na aiki yana hana tarin zafi mai yawa wanda zai iya haɓaka lalacewa, rage fitar da haske, ko haifar da gazawa mai ban tsoro.

Q: Zan iya amfani da wannan LED don nuna ƙarfin wutar lantarki na baya ko kariya?

A: A'a. Takardar bayanin ta bayyana a sarari cewa ba a ƙera na'urar don aikin baya ba. Halin baya (I_R) ma'auni ne don dalilai na gwaji kawai. Yin amfani da ƙarfin wutar lantarki na baya na ci gaba zai iya lalata LED.

Q: Yaya mahimmanci ne rayuwar bene na sa'o'i 168 bayan buɗe jakar shinge na danshi?

A: Yana da mahimmanci sosai ga dogaro. Abubuwan MSL 3 sun sha danshi daga yanayi. Idan an yi musu ginin maimaitawa bayan taga na sa'o'i 168 ba tare da gasa daidai ba, dumama mai sauri zai iya sa danshin da aka kama ya yi tururi nan take, wanda zai iya haifar da rabuwa na ciki ko \"popcorning,\" wanda zai iya fashe marufin kuma ya haifar da gazawa.

10. Ka'idojin Aiki

Wannan na'urar ita ce Diode mai Fitinar Haske (LED) dangane da kayan semiconductor na InGaN (Indium Gallium Nitride) da aka girma akan substrate, wanda ke da alhakin fitar da shudi. Lokacin da aka yi amfani da ƙarfin wutar lantarki na gaba wanda ya wuce kofa na na'urar, electrons da ramuka suna sake haɗuwa a cikin yanki mai aiki na semiconductor, suna sakin makamashi a cikin nau'in photons (haske). Takamaiman abun da ke ciki na gawa na InGaN yana ƙayyade makamashin bandgap, wanda ke da alaƙa kai tsaye da tsayin zango (launi) na hasken da aka fitar—a wannan yanayin, kusan 470 nm (shudi). Marufin ruwan tabarau na epoxy yana aiki don kare gwayar semiconductor, fitar da haske yadda ya kamata, da siffata radiation ɗin da aka fitar zuwa tsarin kusurwar kallo da ake so.
