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

Q1: Wane resistor nake buƙata don wadata 5V?
A1: Nufin yanzun tuƙi mai aminci na 20mA tare da V na yau da kullun_Fna 2.0V: R = (5V - 2.0V) / 0.020A = 150 Ω. Yi amfani da ƙimar daidaitaccen da ta fi kusa (misali, 150Ω ko 160Ω) kuma duba ƙimar wutar lantarki na resistor (P = I²R = 0.06W, don haka resistor 1/8W ko 1/4W yana da kyau).

Q2: Zan iya tuƙa wannan LED da 3.3V?
A2: I. Amfani da lissafi iri ɗaya: R = (3.3V - 2.0V) / 0.020A = 65 Ω. Daidaitaccen resistor na 68Ω zai haifar da ɗan ƙaramin yanzu (~19.1mA), wanda ya yarda.

Q3: Yaya haske 20 mcd?
A3: Millicandelas 20 haske ne mai matsakaici wanda ya dace da aikace-aikacen nuna alama na cikin gida inda za a duba shi daga nesa mai nisa. Yana bayyane a cikin yanayin hasken daki na yau da kullun.

Q4: Me ake nufi da "Kore Mai Haske Zaitun"?
A4: Wannan suna ne na bayyani don launin da tsayin tsayinsa mai rinjaye na kusan 573 nm ya ayyana. Yana tsakanin kore mai tsafta (~525 nm) da rawaya mai tsafta (~590 nm) akan bakan.

Q5: Ana buƙatar mai sanyaya zafi?
A2: Don ci gaba da aiki a matsakaicin yanzu na cikakke na 25mA a cikin babban yanayin yanayi, la'akari da zafi yana da mahimmanci. Don amfani na yau da kullun a 20mA a yanayin daki, alamun PCB yawanci sun isa. Dubi lanƙwasan rage ƙima don aiki mai zafi.

10. Misalin Amfani na Aiki

Yanayi: Ƙirar alamar kunna wuta don kwamfutar tebur.
Ai watar:An sanya LED akan gaban panel. An haɗa shi a jere tare da resistor mai iyakance yanzu na 180Ω zuwa layin wutar lantarki na tsaye na 5V na uwar garken. Lokacin da aka toshe kwamfutar (ko da a kashe), layin 5VSB yana aiki, yana haskaka LED tare da kusan 16.7mA ((5V-2.0V)/180Ω), yana ba da bayyananniyar alamar "tsaye". Faɗin kusurwar kallo yana tabbatar da ganuwa daga kusurwoyi daban-daban. Ƙarancin amfani da wutar lantarki (~50mW don LED+resistor) ba kome ba ne. Halogen-Free da biyayya ga RoHS sun cika ka'idojin muhalli da ake buƙata don kera kwamfuta.

11. Gabatarwar Ka'idar Aiki

Wannan LED yana aiki bisa ka'idar electroluminescence a cikin diode semiconductor. Yankin aiki ya ƙunshi guntu semiconductor na AlGaInP (Aluminum Gallium Indium Phosphide). Lokacin da aka yi amfani da ƙarfin gaba, electrons daga yankin n-type da ramuka daga yankin p-type ana shigar da su cikin yankin aiki. Lokacin da waɗannan masu ɗaukar caji suka sake haɗuwa, suna sakin makamashi a cikin nau'in photons (haske). Takamaiman abun da ke cikin gami na AlGaInP yana ƙayyade makamashin bandgap, wanda kuma yana ƙayyade tsayin tsayi (launi) na hasken da aka fitar—a wannan yanayin, kusan 573-575 nm don kore-zaitun. Fakitin resin na epoxy yana aiki don kare guntu na semiconductor, yana aiki azaman ruwan tabarau don siffata katakon fitar da haske (kusurwar kallo na digiri 100), kuma yana haɓaka ingancin cire haske.

12. Trends na Fasaha (Hangen Nesa na Haƙiƙa)

Masana'antar LED na ci gaba da haɓaka. Duk da yake wannan daidaitaccen fakitin fitila ne ta hanyar rami, faɗaɗa trends da ke tasiri irin waɗannan abubuwan sun haɗa da:
Ƙara Ingantaccen Aiki:Binciken kimiyyar kayan aiki na ci gaba yana nufin inganta ingantaccen ƙididdiga na ciki (IQE) da ingancin cire haske (LEE) na LED ɗin AlGaInP, mai yuwuwa haifar da mafi girman haske a yanzu ɗaya ko haske iri ɗaya a ƙaramin wutar lantarki.
Ƙananan Girma:Akwai sauyin kasuwa gabaɗaya zuwa fakitin na'urar hawa saman (SMD) (kamar 0603, 0402) don alamomi saboda ƙaramin sawun su da dacewa da haɗaɗɗen ɗauka da sanyawa, kodayake fakitin ta hanyar rami sun kasance masu dacewa don samfuri, gyara, da wasu aikace-aikace masu ƙarfi.
Daidaiton Launi:Ci gaba a cikin girma na epitaxial da hanyoyin rarraba suna ba da damar ƙarin sarrafa tsayin tsayi mai rinjaye da ƙarfin haske, suna ba da mafi daidaitaccen launi da haske daga na'ura zuwa na'ura a cikin rukunin samarwa.
Dogaro da Tsawon Rayuwa:Haɓaka abubuwan fakitin (epoxy, silicone) da dabarun haɗin mutuwa suna ci gaba da haɓaka dogon lokaci na dogaro da kiyaye lumen na LED, musamman a ƙarƙashin yanayin aiki mai zafi.
