An yi wannan nunin don kayan aikin lantarki na yau da kullun ciki har da kayan aikin ofis, na'urorin sadarwa, da aikace-aikacen gida. Misalai sun haɗa da na'urori masu auna lambobi da yawa, rediyon agogo, na'urorin ƙidayar lokaci na kayan aiki, karatun firikwensin masana'antu, da ma'aunin allon.

2 Abubuwan Ƙira da Gargaɗi

Ƙirar Da'irar Mai Tuƙi:Ana ba da shawarar tuƙi na lantarki na dindindin fiye da ƙarfin lantarki na dindindin don tabbatar da daidaiton ƙarfin haske da tsawon rai, saboda ƙarfin lantarki na gaba (VF) yana da iyaka kuma yana bambanta da zafin jiki. Dole ne a ƙirƙiri da'irar don ɗaukar cikakken kewayon VF (2.1V zuwa 2.6V na yau da kullun). Kariya daga ƙarfin lantarki na baya da ƙwanƙwasa na wucin gadi yayin zagayowar wutar lantarki yana da mahimmanci don hana lalacewa daga ƙaura na ƙarfe da ƙaruwar lantarki mai ɓarna.

Zaɓin Lantarki:Dole ne a zaɓi lantarkin aiki yana la'akari da matsakaicin zafin yanayi, ta amfani da ƙayyadaddun raguwar lantarki. Wucewa da ƙima yana haifar da lalacewar haske mai tsanani ko gazawa.

Taron Na Gani:Idan an yi amfani da allon gaba ko murfi, bai kamata ya danna kai tsaye akan fim ɗin tsarin nunin ba, saboda hakan na iya haifar da motsi. Don tarukan lambobi da yawa, ana ba da shawarar yin amfani da nunin daga rukunin ƙarfin haske iri ɗaya don guje wa rashin daidaiton haske (rashin daidaiton launi).

Muhalli:A guji fallasa nunin zuwa saurin canjin zafin jiki a cikin yanayi mai ɗanɗano don hana hazo.

9. Kwatancen Fasaha da Bambance-bambance

Duk da yake ba a ba da kwatancen kai tsaye da wasu samfura ba, mahimman bambance-bambancen LSHD-7801 a cikin rukuninsa (lamba guda 0.3-inch) sun haɗa da amfani da takamaiman fasahohin ƙananan na'urori na LED kore (GaP da AlInGaP) don launinsa, bayyanannen rarraba don daidaiton ƙarfin haske, faɗin kewayon zafin aiki (-35°C zuwa +105°C), da bin buƙatun maras gubar/RoHS. Babban haske na yau da kullun (1600 ucd a 10mA) da ƙarancin buƙatun wutar lantarki suma fa'idodin gasa ne.

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

Q: Menene bambanci tsakanin tsayin zango mafi girma (λp) da tsayin zango mai rinjaye (λd)?

A: Tsayin zango mafi girma shine tsayin zango inda bakan fitarwa yake da ƙarfin girma. Tsayin zango mai rinjaye shine tsayin zango guda na haske mai launi ɗaya wanda ya dace da launin da ake gani na fitarwar LED. Ga LED kore, sau da yawa suna kusa, kamar yadda aka gani a nan (565 nm da 569 nm).

Q: Me yasa ake ba da shawarar tuƙi na lantarki na dindindin?

A: Hasken LED shine aikin lantarki na farko, ba ƙarfin lantarki ba. Ƙarfin lantarki na gaba (VF) yana bambanta daga raka'a zuwa raka'a kuma yana raguwa tare da ƙaruwar zafin jiki. Tushen lantarki na dindindin yana tabbatar da cewa an kiyaye fitarwar hasken da ake so ba tare da la'akari da waɗannan bambance-bambancen VF ba, yana samar da ingantaccen aiki da kare LED daga wuce gona da iri idan VF ya ragu.

Q: Zan iya tuƙa shi da wadatar 5V da resistor?

A: I, wannan hanya ce ta gama gari. An ƙididdige ƙimar resistor na jerin R kamar R = (Vsupply - VF) / IF. Ta amfani da VF=2.6V na yau da kullun da IF=10mA tare da wadatar 5V: R = (5 - 2.6) / 0.01 = 240 Ohms. Dole ne ku tabbatar cewa ƙimar wutar lantarki ta resistor ta isa (P = IF^2 * R). Wannan hanyar tana ba da kusan lantarki na dindindin idan Vsupply yana da ƙarfi kuma ya fi girma fiye da bambancin a cikin VF.

Q: Me yake nufi da "anode gama gari"?

A: Yana nufin cewa anodes (bangarori masu kyau) na duk LED na sassa daban-daban an haɗa su tare a ciki zuwa fil ɗaya ko fiye (fil 1 & 6 a wannan yanayin). Don haskaka wani sashe, dole ne a haɗa fil ɗin cathode ɗinsa daidai zuwa ƙaramin ƙarfin lantarki (ƙasa) yayin da fil ɗin anode gama gari yana riƙe da ƙarfin lantarki mai kyau.

11. Ƙirar Aiki da Yanayin Amfani

Harka: Ƙirar karatun voltmeter mai lamba 3 mai sauƙi.

Za a yi amfani da nunin LSHD-7801 guda uku. Microcontroller tare da isassun fil ɗin I/O zai sarrafa sassan. Yawanci ana amfani da dabarar haɗawa don rage adadin fil: microcontroller yana tuƙa anodes gama gari na kowane lamba a jere, yayin da layukan cathode na duk sassan suke raba. Wannan yana haifar da tunanin cewa duk lambobin suna kan tare idan sauyi ya yi sauri sosai. Dole ne ƙirar ta haɗa da resistors masu iyakance lantarki akan kowane layin cathode (ko amfani da IC mai tuƙi na lantarki na dindindin). Dole ne software ya ƙididdige daidaitattun sifofin sassa don 0-9 kuma ya sarrafa lokacin haɗawa. Abubuwan da suka shafi zafi sun haɗa da tabbatar da tsarin PCB yana ba da damar ɓarnawar zafi, musamman idan an tuƙa shi a manyan lantarki a cikin akwati mai dumi.

12. Gabatarwar Ka'ida

Ka'idar aiki ta dogara ne akan electroluminescence a cikin kayan semiconductor. Lokacin da aka yi amfani da ƙarfin lantarki na gaba wanda ya wuce kofa na kunna diode a kan ƙaramin LED (GaP ko AlInGaP), electrons da ramuka suna sake haɗuwa a cikin yanki mai aiki, suna sakin makamashi a cikin nau'in photons (haske). Ƙarfin bandgap na takamaiman kayan semiconductor yana ƙayyade tsayin zango (launi) na hasken da aka fitar. A cikin nunin 7-segment, an tsara ƙananan na'urori na LED da yawa a cikin tsari kuma an haɗa su a bayan abin rufe fuska tare da sifofin sassa. Ta hanyar zaɓar amfani da lantarki ga haɗuwa daban-daban na waɗannan ƙananan na'urori, ana iya samar da lambobi da wasu haruffa.
