10. Tambayoyin da ake yawan yi (FAQ)

Q1: Menene matsakaicin karfin gaba don tuƙi wannan LED?

A1: Matsakaicin V_Fyana kusa da 2.85V a 5mA, amma yana iya bambanta daga 2.55V zuwa 3.15V. Koyaushe ka tsara don matsakaicin V_Fa cikin kwandon da kuka zaɓa don tabbatar da cewa an sami halin da ake so.

Q2: Zan iya tuƙi wannan LED tare da 20mA akai-akai?

A2: Ee, 20mA shine matsakaicin halin gaba na DC da aka ba da shawarar. Yin aiki a wannan matsakaicin zai haifar da mafi girman fitar da haske amma yana iya rage tsawon rayuwa idan aka kwatanta da ƙananan halaye. Koyaushe ka yi la'akari da sarrafa zafi.

Q3: Ta yaya zan fassara zanen Rarrabawar Hue (Shafi na 5)?

A3: Zanen yana zana kwandon takwas (A1-A8) akan ginshiƙi na launi na CIE 1931. Kowane kwandon ƙaramin yanki ne mai siffar huɗu. Ma'auni (x, y) a cikin tebur suna ayyana kusurwoyin waɗannan siffofi. Kuna zaɓar lambar kwandon don tabbatar da cewa wurin launi na LED ya faɗi cikin wannan yanki na musamman akan ginshiƙi.

Q4: Tsarin hadawa na yana amfani da bayanin reflow tare da kololuwar 250°C. Shin wannan yana da kyau?

A4: Ee, kololuwar 250°C tana cikin ƙayyadaddun iyaka na 260°C max. Tabbatar da cewa jimlar lokacin da ya wuce yanayin zafi na ruwa mai ruwa da ƙimar ramuka ana sarrafa su bisa ga daidaitattun jagororin SMT.

Q5: Me yasa kariyar ESD ke da mahimmanci ga LED?

A5: Haɗin semiconductor a cikin LED yana da hankali sosai ga fitar da wutar lantarki mai ƙarfi, wanda zai iya lalata ko lalata na'urar nan take. Lalacewar ESD bazai bayyana nan take ba amma yana iya haifar da gazawar da ba ta dace ba ko canza aiki.
