8. Shawarwari na Aikace-aikace

8.1 Da'irori na Aikace-aikace na Yau da Kullun

Tsarin ginin LED na gama-gari ya dace da turawa da yawa. Da'ira ta yau da kullun ta ƙunshi amfani da microcontroller ko takamaiman IC direban nuni. Microcontroller zai bi da bi ya kunna (saita zuwa babban dabaru ko haɗa zuwa Vcc ta hanyar transistor) ginin LED na gama-gari na lamba ɗaya a lokaci guda, yayin da yake fitar da tsarin sassan (katod) na wannan lamba, sau da yawa ta hanyar resistors masu iyakancewar halin yanzu ko direba mai zubar da halin yanzu akai-akai. Wannan haɗakarwa yana faruwa da sauri fiye da yadda idon mutum zai iya gani, yana haifar da ruɗi na duk lambobi suna kunne a lokaci guda, yayin da yake rage adadin ƙafafun I/O na microcontroller da ake buƙata sosai.

8.2 Abubuwan da ake la'akari da Ƙira

Iyakancewar Halin Yanzu: Mai mahimmanci don hana wucewa mafi girman ci gaba da ƙarfin gaba (25mA kowane sashi). Dole ne a ƙididdige resistors ko direbobi na halin yanzu akai-akai bisa ga ƙarfin wutar lantarki da ƙarfin wutar gaba na LED (VF).Mita Haɗakarwa: Dole ne ya zama mai girma sosai don guje wa ƙyalli da ake iya gani, yawanci sama da 60-100 Hz.Ƙarfin Kololuwa: A cikin ƙirar da aka haɗa, halin yanzu na nan take yayin ɗan gajeren lokacin KUNNA zai iya zama mafi girma fiye da matsakaicin halin yanzu na DC. Tabbatar cewa ƙarfin kololuwa bai wuce ƙimar 90mA ba.Kusurwar Kallo: Faɗin kusurwar kallo yana ba da sassauci a matsayin ɗora dangane da mai amfani.Bambanci: Ƙirar fuskar launin toka/sashi fari tana ba da bambanci mai kyau; guji ɗora a bayan tagogi masu launi mai zurfi wanda zai rage hasken ja.

9. Kwatancen Fasaha da Bambance-bambance

Babban abin da ya bambanta LTC-5837JD shine amfani da fasahar LED Hyper Red AlInGaP. Idan aka kwatanta da tsofaffin fasahohi kamar daidaitattun LED jajayen GaAsP (Gallium Arsenide Phosphide), AlInGaP yana ba da ingantaccen ingantaccen haske sosai, yana haifar da mafi haske don halin yanzu iri ɗaya, ko haske iri ɗaya a ƙaramin wutar lantarki. Hakanan yawanci yana ba da ingantaccen kwanciyar hankali na tsawon zango akan zafin jiki da tsawon rai. Tsawon lamba 0.52-inch matsakaicin girma ne, amma haɗuwar haske mai ƙarfi, bambanci, da takamaiman kayan ado na launin toka/fari na iya bambanta shi da sauran nuni a cikin ajinsa.

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

Q: Menene manufar lakabin \"Hyper Red\"?

A: Yana nuna LED yana fitar da haske a tsawon zango mafi tsayi (~650nm) idan aka kwatanta da daidaitattun LED jajaye (~630nm). Wannan ja mai zurfi na iya bayyana mafi ƙarfi kuma yana iya samun mafi kyawun aiki a wasu tsarin tacewa na gani.

Q: Zan iya turawa wannan nuni tare da microcontroller 5V ba tare da direbobi na waje ba?

A: Mai yiwuwa, amma da taka tsantsan. Yawanci VF shine 2.6V. Tare da samar da wutar lantarki 5V, resistor mai iyakancewar halin yanzu ya zama dole. Ƙimar resistor R = (Vcc - VF) / IF. Don IF=10mA, R = (5 - 2.6) / 0.01 = 240 Ohms. Hakanan dole ne ku tabbatar cewa ƙafafun I/O na microcontroller na iya zubar da jimillar halin yanzu na sashi lokacin da aka kunna sassa da yawa a cikin lamba yayin haɗakarwa.

Q: Me \"Ginin LED na Gama-gari\" ke nufi ga ƙirar da'irata?

A: Yana nufin duk anodes (bangarori masu kyau) na LED na lamba ɗaya an haɗa su tare. Don haskaka sashi, kuna amfani da ƙarfin wutar lantarki mai kyau zuwa ƙafar ginin LED na gama-gari na wannan lamba kuma ku haɗa ƙafar katod ɗin sashin da ake so zuwa ƙasa (ta hanyar mai iyakancewar halin yanzu). Wannan ya saba da nuni na katod na gama-gari.

11. Ƙirar Aiki da Lamarin Amfani

Lamari: Ƙirar Karatun Voltmeter mai Lamba 4.Mai ƙira yana gina samar da wutar lantarki na benci kuma yana buƙatar nuni mai haske na ƙarfin wutar lantarki. Sun zaɓi LTC-5837JD saboda haskensa da girmansa. Microcontroller (misali, ARM Cortex-M ko PIC) yana da iyakacin I/O. Ta amfani da tsarin haɗakarwa, suna buƙatar ƙafafu 4 kawai don anodes na lamba (ana sarrafa su ta hanyar transistors NPN ko MOSFETs) da ƙafafu 8 don katod ɗin sashi (sassa 7 + maki goma). Firmware yana bincika lambobi 1-4 da sauri. Mai canza analog-zuwa-lambar yana karanta ƙarfin wutar lantarki, ya canza shi zuwa tsarin BCD, kuma firmware yana duba tsarin sassan da suka dace daga tebur, yana fitar da su a lokaci guda tare da kunna anode. An sanya resistors masu iyakancewar halin yanzu akan layukan katod. Fuskar launin toka tana ba da kamanni na ƙwararru a kan panel ɗin kayan aiki.

12. Gabatarwar Ka'ida

Nuni mai sassa bakwai tarin ƙwayoyin LED ne da aka jera a cikin tsarin siffa takwas. Kowane ɗayan sassa bakwai (mai lakabin A zuwa G) LED ne na mutum. Ta hanyar haskaka takamaiman haɗuɗɗun waɗannan sassan, ana iya samar da duk lambobi goma (0-9) da wasu haruffa. A cikin nuni mai lambobi da yawa kamar wannan, kowane lamba saiti ne na sassa daban, amma sassan da suka dace (misali, duk sassan 'A') sau da yawa suna da 'yancin kai na lantarki don ba da damar sarrafa haɗakarwa, wanda ke rage adadin ƙafafun haɗin kai da ake buƙata.

13. Trends na Ci gaba

Trend a cikin nuni na LED mai sassa bakwai yana ci gaba zuwa ga ingantaccen inganci, yana ba da damar nuni mai haske a ƙarancin amfani da wutar lantarki, wanda ke da mahimmanci ga na'urorin da ke da baturi. Haɗin kai wani trend ne, tare da da'irar direban nuni, wani lokacin har ma ya haɗa da microcontroller, ana haɗa shi cikin na'urar nuni da kanta, yana sauƙaƙe ƙirar tsarin. Hakanan akwai motsi zuwa ga gamut mai faɗi da amfani da kayan ci gaba kamar AlInGaP da InGaN (don shuɗi/kore) don inganta aiki da aminci. Duk da haka, ga yawancin aikace-aikacen masana'antu da kayan aikin aunawa, ƙirar ta hanyar rami na gargajiya tare da jajaye mai haske ya kasance sananne saboda ingantaccen amincinsa, bambanci mai kyau, da sauƙin ƙira.
