Waɗannan fasalulluka sun haɗu don ba da nuni mai babban haske, ingantaccen aminci, da sassauƙar ƙira don aikace-aikacen masu kula da farashi amma masu mayar da hankali kan aiki.

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

Q1: Menene bambanci tsakanin tsayin raƙuman ruwa na kololuwa (639nm) da tsayin raƙuman ruwa mai rinjaye (631nm)?

A: Tsayin raƙuman ruwa na kololuwa shine kololuwar zahiri na fitowar bakan. Tsayin raƙuman ruwa mai rinjaye shine tsayin raƙuman ruwa guda ɗaya wanda idon ɗan adam ke gani wanda ya dace da launin tushen haske. Sau da yawa suna kusa amma ba iri ɗaya ba saboda siffar bakan fitarwa.

Q2: Shin zan iya tuƙa wannan nuni da fil ɗin microcontroller na 5V kai tsaye?

A: A'a. Ƙarfin lantarki na gaba shine 2.0-2.6V kawai. Haɗa tushen 5V kai tsaye ba tare da resistor mai iyakance halin yanzu ba zai lalata LED. Dole ne ka yi amfani da resistor na jeri ko, zai fi dacewa, mai tuƙi na halin yanzu na dindindin don iyakance halin yanzu zuwa ƙimar aminci (misali, 10-20mA).

Q3: Me yasa ake ba da shawarar tuƙi na halin yanzu na dindindin?

A: Hasken LED shine aikin halin yanzu da farko, ba ƙarfin lantarki ba. Ƙarfin lantarki na gaba (VF) yana da haƙuri kuma yana bambanta da zafin jiki. Tushen halin yanzu na dindindin yana tabbatar da haske ya kasance barga ba tare da la'akari da waɗannan bambance-bambancen VF ba, yana haifar da aiki mafi daidaito da tsinkaya.

Q4: Ta yaya zan aiwatar da yawan aiki (multiplexing)?

A: Don nuna lamba akan lambobi uku, za ku yi zagaye cikin sauri (multiplex) tsakanin su. Misali, kunna anodes na sassa don Lamba 1, kunna cathode gama gari, jira ɗan lokaci kaɗan, saka kashe wannan cathode. Na gaba, saita anodes don Lamba 2, kunna cathodensa, da sauransu. Zagayowar yana da sauri sosai (yawanci >100Hz) har idon ɗan adam yana ganin duk lambobin a matsayin mai haske ci gaba.

10. Ƙira na Aiki da Lamarin Amfani

Yanayi: Ƙirar nuni mai sauƙi na voltmeter mai lamba 3.

1. Microcontroller:Zaɓi MCU mai isassun layukan I/O: layukan sassa 7 (A-G) + layin maki goma 1 + layukan zaɓin lamba 3 (cathodes gama gari) = layuka 11 aƙalla.

2. Da'irar Tuƙi:Tun da fil ɗin MCU ba zai iya samar da/ɗaukar isassun halin yanzu ga duk sassa lokaci ɗaya ba, yi amfani da jerin transistor (misali, ULN2003) don ɗaukar halin yanzu na cathode ga kowane lamba. Za a iya samun halin yanzu na anode na sassa daga fil ɗin MCU idan suna cikin iyakoki, ko ta hanyar ƙarin masu tuƙi.

3. Ƙuntata Halin Yanzu:Sanya resistor mai iyakance halin yanzu a jere tare da kowane layin anode na sashi. Lissafa ƙimar resistor bisa ga ƙarfin lantarkin ku (Vcc), ƙarfin lantarki na gaba na LED (yi amfani da matsakaicin VF=2.6V don mafi munin yanayi), da halin yanzu da ake so (misali, 10mA): R = (Vcc - VF) / IF.

4. Software:Ai wata katsewar timer don yawan aiki (multiplexing). A cikin aikin hidimar katsewa, kashe lambar da ta gabata, sabunta tsarin sashi don lamba ta gaba daga teburin nema, saka kunna cathodenta.

5. La'akari da Zafi:Tabbatar cewa ba a sanya nuni kusa da wasu sassan da ke haifar da zafi ba. Idan ana tsammanin zafin yanayi zai yi zafi, yi la'akari da rage halin yanzu na tuƙi ƙasa da matsakaici don rage rushewar wutar lantarki.

11. Gabatarwa da Ka'idar Aiki

LTC-4724JR ya dogara ne akan electroluminescence na semiconductor. Lokacin da aka yi amfani da ƙarfin lantarki na gaba wanda ya wuce kofa na kunna diode a kan haɗin p-n na AlInGaP, ana shigar da electrons da ramuka cikin yanki mai aiki. Haɗuwarsu yana sakin makamashi a cikin nau'in photons (haske). Takamaiman abun da ke cikin gawa na AlInGaP yana ƙayyade makamashin bandgap, wanda ke ayyana tsayin raƙuman ruwa (launi) na hasken da aka fitar—a wannan yanayin, super red (~631-639nm). Abu marar gani na GaAs substrate yana taimakawa wajen nuna haske sama, yana inganta ingancin cire haske. Tsarin sassa bakwai (seven-segment) tsari ne na daidaitaccen tsari inda aka haskaka haɗuwa daban-daban na sassa bakwai masu sarrafawa daban (A zuwa G) don samar da lambobi 0-9 da wasu haruffa.

12. Trends na Fasaha

Masana'antar nuni na LED tana ci gaba da haɓaka. Duk da yake wannan samfurin yana amfani da fasahar AlInGaP mai girma da aminci, manyan abubuwan da ke tasiri wannan sashe sun haɗa da:
