Babban lambar sashi shine LTC-5336JD. Bayanin ya ƙayyade cewa AlInGaP Ja Mai Tsananin Haske ne, Nunin Cathode Gama Gari tare da ma'auni na hannun dama. Duk da yake ba a jera cikakkun ƙayyadaddun fakiti (misali, tire, bututu, reel) da adadi a cikin wannan ɓangaren ba, fakiti na al'ada don irin waɗannan nunin fil da yawa yana cikin bututu ko tire masu hana tsayayya don kare filayen yayin jigilar kaya da sarrafawa. Alamar za ta haɗa da lambar sashi, lambar kuri'a, da yuwuwar bayanin rarrabawa.

8. Shawarwarin Aikace-aikace

8.1 Yanayin Aikace-aikace na Al'ada

Wannan nunin ya dace da kowane aikace-aikacen da ke buƙatar karatun lambobi da yawa mai ƙarfi, amintacce, da haske. Misalai sun haɗa da: na'urorin auna lantarki da na'urorin danna, na'urorin ƙidaya mitar, na'urorin ƙidayar lokaci da ƙidayar, ma'auni, masu sarrafa tsarin HVAC, nunin kayan aikin binciken mota, da kayan aikin dakin gwaje-gwaje. Faɗin kewayon zafinsa yana sa ya dace da aikace-aikacen cikin gida da na waje masu kariya.

8.2 Abubuwan da Ake La'akari da Ƙira

Lokacin ƙira tare da LTC-5336JD, dole ne a yi la'akari da abubuwa da yawa:Hanyar Tuƙi: Tsarin fil ɗin cathode gama gari an inganta shi don yawan aiki. Microcontroller na iya jere ƙasa kowane cathode na lamba yayin amfani da daidaitattun ƙirar anode na sashi ta hanyar transistors ko takamaiman IC mai tuƙi (misali, MAX7219). Wannan yana rage adadin fil ɗin I/O da ake buƙata sosai.Ƙuntatawa na Yanzu: Masu hana ƙarfin lantarki na waje wajibi ne ga kowane anode na sashi (ko kuma ya kamata a yi amfani da mai tuƙi na ƙarfin lantarki akai-akai) don hana wuce matsakaicin ƙarfin gaba na ci gaba, musamman mahimmanci lokacin da ake yawan aiki kamar yadda matsakaicin ƙarfin lantarki zai iya zama mafi girma. Ana ƙididdige ƙimar resistor bisa ga ƙarfin wutar lantarki, ƙarfin wutar gaba na LED (VF), da ƙarfin sashi da ake so.Gudanar da Zafi: Duk da yake na'urar da kanta ba ta ɓarke da zafi mai yawa a kowane sashi, zafin gama gari daga sassa da yawa da ake haskakawa lokaci guda, musamman a ƙarfin lantarki mafi girma, ya kamata a yi la'akari. Ana ba da shawarar isasshen iska a cikin akwati.Kusurwar Dubawa: Ya kamata a yi amfani da faɗin kusurwar kallo a cikin ƙirar injiniya don tabbatar da cewa an daidaita nunin daidai ga mai amfani na ƙarshe.

9. Kwatancen Fasaha da Bambance-bambance

Idan aka kwatanta da tsofaffin fasahohi kamar na'urorin haske ko na'urorin nuni na fluorescent (VFDs), LTC-5336JD yana ba da fa'idodi mafi girma: ƙarancin amfani da wutar lantarki, mafi ingantaccen aminci (babu filament da zai ƙone), saurin amsawa mafi sauri, da mafi kyawun juriya ga girgiza. Idan aka kwatanta da daidaitattun LED na ja GaAsP ko GaP, fasahar AlInGaP tana ba da inganci da haske mafi girma, wanda ke haifar da mafi kyawun ganuwa. Idan aka kwatanta da na zamani dot-matrix ko OLED na zane, wannan nunin sassa bakwai yana ba da sauƙin sarrafa bayanan lambobi, ƙarancin farashi, kuma sau da yawa mafi girman haske mafi girma don karanta hasken rana, ko da yake yana da iyakaccen saitin haruffa (galibi 0-9 da wasu haruffa). Babban bambance-bambancensa shine haɗin takamaiman tsayin lamba 0.52-inch, tsarin lamba uku, launin ja mai tsananin haske, da ƙirar cathode gama gari a cikin fakitin da ya dace da RoHS.

10. Tambayoyin da Ake Yawan Yi (Bisa Ma'auni na Fasaha)

Q: Menene manufar "fuska mai launin toka da sassa farare" da aka ambata a cikin bayanin?

A: Wannan fasalin ƙira ne na gani. Fuskar launin toka tana ɗaukar hasken yanayi, tana rage haske da inganta bambanci. Sassa fararen suna aiki azaman mai watsawa da mai nuna haske ga hasken ja da guntu na LED ke fitarwa, yana taimakawa wajen ƙirƙirar kamannin sashi mai haske iri ɗaya.

Q: Ta yaya zan fassara ƙayyadaddun "Rage Ƙarfin Gaba na Ci Gaba"?

A: Matsakaicin ƙarfin lantarki na ci gaba na 25 mA yana aiki ne kawai a zafin yanayi na 25°C. Ga kowane digiri Celsius sama da 25°C, dole ne ku rage matsakaicin ƙarfin lantarki da aka yarda da shi da 0.33 mA. Misali, a zafin yanayi na 50°C, matsakaicin ƙarfin lantarki zai zama 25 mA - (0.33 mA/°C * 25°C) = 25 mA - 8.25 mA = 16.75 mA a kowane sashi.

Q: Zan iya tuƙa wannan nunin da microcontroller 5V kai tsaye?

A: A'a, ba za ku iya haɗa anodes na sassi kai tsaye zuwa fil ɗin microcontroller 5V ba. Matsakaicin ƙarfin wutar gaba shine 2.6V, don haka koyaushe ana buƙatar resistor mai hana ƙarfin lantarki. Bugu da ƙari, fil ɗin microcontroller mai yiwuwa ba zai iya samar da/ɗaukar isasshen ƙarfin lantarki ba (har zuwa 25 mA a kowane sashi). Kuna buƙatar transistors masu tuƙi ko takamaiman IC mai tuƙi na LED tsakanin microcontroller da nunin.

11. Ƙirar Aiki da Yanayin Amfani

Harka: Ƙirar Karatun Voltmeter mai Lamba 3

Injiniya yana ƙirar voltmeter na dijital mai sauƙi don auna 0-30V DC. ADC na microcontroller yana ba da ƙimar dijital. Ana buƙatar nuna wannan ƙimar akan LTC-5336JD. Matakan ƙira za su haɗa da: 1.Haɗin Microcontroller: Yi amfani da fil ɗin I/O 7 don anodes na sashi (A-G) da fil ɗin I/O 3 don cathodes na lamba (Lamba 1, 2, 3). Kowane fil ɗin I/O zai sarrafa transistor (misali, NPN don cathodes, PNP ko NPN+inverter don anodes, ko kuma amfani da takamaiman IC mai tuƙi). 2.Tsarin Yawan Aiki: Firmware zai aiwatar da katsewar timer. A cikin kowane zagaye na katsewa, yana kashe duk lambobi, yana ƙididdige ƙirar sashi don lamba ta gaba bisa ga lambar da za a nuna, yana amfani da wannan ƙirar ga masu tuƙi na anode, sannan ya kunna (ƙasa) cathode don wannan takamaiman lamba. Wannan yana zagayowa cikin sauri tsakanin lambobi uku, yana haifar da tunanin cewa duk lambobi suna haskakawa lokaci guda. 3.Ƙididdigar Ƙarfin Yanzu: Idan ana amfani da wutar lantarki 5V (Vcc) da nufin ƙarfin sashi (Iseg) na 10 mA, ƙimar resistor mai hana ƙarfin lantarki R = (Vcc - VF) / Iseg = (5V - 2.6V) / 0.01A = 240 Ohms. Ana iya amfani da daidaitaccen resistor na 220 ko 270 Ohm. 4.Ma'auni: Ana iya amfani da ma'auni na hannun dama don nuna wurin ma'auni, wanda takamaiman fil ɗin anode da cathode na lambar da ta dace ke sarrafa shi.

12. Gabatar da Ƙa'idar Aiki

Babban ƙa'idar aiki ta dogara ne akan electroluminescence a cikin haɗuwar p-n semiconductor. Tsarin kayan AlInGaP semiconductor ne kai tsaye. Lokacin da aka yi amfani da ƙarfin wutar gaba wanda ya wuce kofa na haɗuwa (kusan 2.1-2.6V), 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 gawa na AlInGaP yana ƙayyade ƙarfin bandgap, wanda kai tsaye yayi daidai da tsayin raƙuman ruwa (launi) na hasken da ake fitarwa—a wannan yanayin, ja mai tsananin haske a 650 nm. Abun da ba shi da gani na GaAs yana ɗaukar duk wani hasken da aka fitar ƙasa, yana inganta bambanci. Hasken da aka fitar sama yana ratsa ta cikin yadudduka na semiconductor kuma an siffanta shi ta hanyar fakitin filastik da aka gyara tare da fuskar sa mai launin toka da masu watsawa na sassa farare don samar da sanannen halayen sassa bakwai.
