8. Tambayoyin da Ake Yawan Yi (FAQs)

Q: Menene bambanci tsakanin tsawon zango mai kololuwa da tsawon zango mai rinjaye?

A: Tsawon zango mai kololuwa (λP) shine tsawon zango inda mafi girman ƙarfin hasken da aka fitar yake. Tsawon zango mai rinjaye (λd) shine tsawon zango guda ɗaya da idon ɗan adam ke gani wanda ya dace da launin LED, wanda aka lissafta daga ma'auni na launi na CIE. Ga tushen launi ɗaya kamar wannan LED mai launin rawaya, sau da yawa suna kusa sosai, kamar yadda aka gani a nan (588 nm da 587 nm).

Q: Shin zan iya tuƙa wannan LED ba tare da resistor mai ƙuntatawa ba?

A: A'a. LED na'ura ce mai tuƙa yanzu. Haɗa shi kai tsaye zuwa tushen wutar lantarki zai haifar da wuce gona da iri na yanzu, mai yuwuwar wuce matsakaicin ƙididdiga da lalata na'urar. Koyaushe yi amfani da resistor na jerin da ya dace ko direba mai ci gaba da ƙuntatawa.

Q: Me ya sa yanayin ajiya na buɗaɗɗen marufi ya fi tsauri (60% RH da 90% RH)?

A> Da zarar an buɗe jakar shinge na danshi, kayan suna fuskantar danshi na muhalli. Mafi ƙarancin iyaka (60% RH) yana taimakawa hana ɗaukar danshi mai yawa, wanda zai iya haifar da rabuwar ciki ko fashewa a cikin babban tsarin solder na reflow na zafi (wanda aka sani da "popcorning").

Q: Me ake nufi da "duban gefe"?

A> Ba kamar LEDs masu fitarwa na sama inda haske ke fita daidai da PCB ba, LED mai duban gefe yana fitar da haske daidai da saman PCB. Wannan yana da amfani don hasken gefuna, ramuka, ko samar da alamomin matsayi a gefen na'ura.
