Don daidaitaccen daidaitawa a cikin aikace-aikace masu mahimmanci, tuntubi masana'anta don takamaiman lambobin kwandon shara.

Q: Menene ma'anar "sassuna sun dace"?

A> Yana nufin halayen lantarki da na gani (kamar ƙarfin lantarki na gaba da ƙarfin haske) sun yi kama da juna a cikin na'urar ɗaya. Wannan yana tabbatar da daidaiton haske lokacin da aka turawa duk sassuna tare da halin yanzu ɗaya, wanda ba koyaushe ake tabbatar da shi ba a cikin ƙananan nunin.

9. Aikin Zane da Amfani na Aikace-aikace

Yi la'akari da ƙirar ma'aunin bayanan muhalli mai ƙarancin wutar lantarki wanda ke nuna zafin jiki akan karatu na lamba 4. Ta amfani da nunin LTS-10304JD guda huɗu, mai zane zai ƙirƙiri da'irar haɗawa. Microcontroller mai ƙarancin wutar lantarki zai kunna kowane lamba ta hanyar cathode gama gari ta hanyar ƙaramin transistor NPN yayin da yake fitar da tsarin sashe na wannan lamba akan saitin filolin I/O (watakila ta hanyar rajistar motsi ko faɗaɗa tashar don adana fil). Ta hanyar saita halin yanzu na turawa sashe zuwa 2-3mA (da kyau a ƙasa da matsakaicin), ana samun kyakkyawan karantawa yayin da ake rage yawan amfani da wutar lantarki na tsarin. Babban rabo na bambanci yana tabbatar da cewa ana iya karanta nuni a cikin gida da kuma yanayin waje mai inuwa. Faɗin kewayon zafin jiki na nuni ya dace da ƙayyadaddun aikin ma'aunin.

10. Gabatarwar Ka'idar Aiki

Nuni na LED mai sassuna bakwai tarin LED ne da yawa waɗanda aka jera a cikin tsarin adadi takwas. Kowane ɗayan sanduna bakwai (sassuna A-G) da ma'auni (DP) LED ne na mutum. A cikin tsarin cathode gama gari kamar LTS-10304JD, cathodes na duk waɗannan LED na ciki an haɗa su tare zuwa fil ɗaya ko fiye. Don haskaka takamaiman sashe, dole ne a yi amfani da ƙarfin lantarki mai kyau ga takamaiman fil ɗin anode yayin da aka haɗa cathode gama gari zuwa ƙasa (ko ƙarancin ƙarfin lantarki), yana kammala da'irar kuma yana ba da damar halin yanzu ya gudana. Ta hanyar sarrafa waɗanne haɗin sassuna aka kunna, ana iya samar da lambobi 0-9 da wasu haruffa. Tsarin kayan AlInGaP yana fitar da haske lokacin da electrons da ramuka suka sake haɗuwa a cikin yanki mai aiki a ƙarƙashin son zuciya na gaba, tare da takamaiman abun da ke ciki yana ƙayyade tsayin zango ja.

11. Trends na Fasaha da Mahallin

Ci gaban fasahar LED ta AlInGaP a cikin shekarun 1990 ya kasance babban ci gaba don babban haske ja, orange, da LED rawaya. Ya maye gurbin ƙarancin inganci na fasahar GaAsP da GaP a aikace-aikacen da ke buƙatar ganuwa mai yawa.
