• Fil 14: Cathode gama gari donLamba 1.

Zanen da'irar ciki yana nuna tsari na sassan LED 14 (7 kowane lamba, tare da maki goma sha shida biyu) da haɗin su zuwa fil 18. Ana buƙatar haɗawa don tuƙi duka lambobi biyu: ta hanyar sauya kunna cathode na Lamba 1 da Lamba 2 yayin samar da siginar anode don sassan da ake so na lambar aiki, ana iya sarrafa lambobi biyu tare da ƙananan layukan I/O.

6. Jagororin Solder & Taro

Matsakaicin ƙididdiga na iyaka yana ƙayyade bayanin yanayin zazzabin solder: kunshin zai iya jure matsakaicin zazzabi na 260°C har zuwa dakika 3, wanda aka auna a wuri 1.6mm (1/16 inch) ƙasa da wurin zama (watau akan PCB kusa da jagora). Wannan ƙimar daidaitacce ce don hanyoyin solder na reflow maras gubar (misali, ta amfani da solder SAC305). Dole ne masu ƙira su tabbatar da bayanin tanda na reflow ɗin su ya tsaya cikin waɗannan iyakokin don hana lalata guntu na LED ko kunshin filastik. Yakamata a kiyaye matakan kariya na ESD (Electrostatic Discharge) yayin sarrafawa. Ya kamata a adana shi a cikin ƙayyadadden kewayon zazzabi -35°C zuwa +85°C a cikin yanayi mai ƙarancin zafi.

7. Shawarwarin Aikace-aikace

7.1 Da'irori na Aikace-aikacen Yau da Kullun

Don tuƙa wannan nuni, ana buƙatar microcontroller ko takamaiman direba IC. Don nunin cathode gama gari, ana haɗa fil ɗin cathode zuwa ƙasa (ta hanyar sauya transistor don haɗawa), kuma fil ɗin anode ana haɗa su zuwa tushen wutar lantarki mai iyakance (misali, ta hanyar resistor na jerin ko direba mai ci gaba). Ƙarfin wutar lantarki na gaba (V_F) na 2.6V da halin yanzu da ake so (I_F, misali, 10-20 mA don cikakken haske) suna ƙayyade ƙimar resistor na jerin: R = (V_wadata- V_F) / I_F. Idan ana haɗa lambobi biyu a 10 mA kowanne, matsakaicin halin yanzu yayin lokacin kunna lambar zai iya zama 10 mA, amma matsakaicin halin yanzu kowane yanki ya yi ƙasa, yana rage amfani da wutar lantarki.

7.2 Abubuwan da ake la'akari da ƙira

• Iyakance Halin Yanzu:Koyaushe yi amfani da resistors na jerin ko direbobi masu ci gaba. Kada a haɗa LED kai tsaye zuwa tushen wutar lantarki.
• Haɗawa:Mahimmanci ga nunin lambobi da yawa don rage adadin fil. Yakamata ƙimar sabuntawa ta yi girma sosai (>60 Hz) don guje wa flicker da ake iya gani.
• Gudanar da Zafi:Duk da yake LEDs suna da inganci, ɓarnar wutar lantarki (P = V_F* I_F) kowane yanki zai iya kaiwa har zuwa 52 mW (2.6V * 20mA). Tabbatar da isasshen iska, musamman idan ana tuƙi a manyan halin yanzu ko a cikin yanayin zafi mai girma.
• Kusurwar Kallo:Faɗin kusurwar kallo yana da fa'ida amma yi la'akari da layin gani na mai amfani na farko lokacin da ake ɗora nuni.

8. Kwatancen Fasaha

Idan aka kwatanta da tsofaffin fasahohi kamar daidaitattun LEDs ja na GaAsP (Gallium Arsenide Phosphide), LED na AlInGaP Hyper Red yana ba da ingantaccen inganci na haske (ƙarin fitar da haske kowane mA na halin yanzu) da mafi kyawun aiki a manyan yanayin zafi. Idan aka kwatanta da fararen LEDs (sau da yawa blue LED + phosphor), yana ba da mafi girman tsaftar launi da yawanci mafi inganci don hasken ja monochromatic. Tsawon lambobi 0.56" girman girma ne na yau da kullun, yana ba da daidaitaccen ma'auni tsakanin iya karantawa da ƙanƙanta idan aka kwatanta da ƙanana (0.3") ko manyan (0.8") nunin.

9. Tambayoyin da ake yawan yi (Dangane da Sigogi na Fasaha)

Q: Menene bambanci tsakanin tsawon zango kololuwa (650nm) da tsawon zango mai rinjaye (639nm)?

A: Tsawon zango kololuwa shine mafi girman matsayi akan lanƙwasa fitarwa na bakan. Tsawon zango mai rinjaye shine tsawon zango guda ɗaya na hasken monochromatic wanda zai bayyana yana da launi ɗaya ga idon ɗan adam. Sau da yawa suna bambanta kaɗan.

Q: Zan iya tuƙa wannan nuni tare da microcontroller 3.3V?

A: Ee. Tare da V_Fna 2.6V, wadata 3.3V ya isa. Resistor na jerin zai kasance: R = (3.3V - 2.6V) / 0.020A = 35 Ohms. Daidaitaccen resistor 33 ko 39 Ohm zai dace.

Q: Me yasa matsakaicin halin gaba (90mA) ya fi girma fiye da halin yanzu na ci gaba (25mA)?

A> LED zai iya ɗaukar gajerun bugun jini, manyan halin yanzu ba tare da zafi sosai ba, yana ba da damar tsare-tsaren haɗa nunin mai haske (inda kowane lamba yana kunne ne kawai na ɗan lokaci) ko don ƙirƙirar walƙiya mai haske sosai.

Q: Menene ma'anar "AlInGaP epi akan GaAs substrate"?

A> Layukan da ke fitar da haske (layukan epitaxial ko "epi") an yi su ne da Aluminum Indium Gallium Phosphide. Ana girma waɗannan akan wafer na Gallium Arsenide (GaAs) wanda ke ba da tallafi na tsari amma ba shine ainihin kayan fitar da haske ba.

10. Misalin Amfani na Aiki

Yanayi: Ƙirar nuni na voltmeter na lambobi mai sauƙi.

Da'irar voltmeter tana samar da fitarwar BCD (Binary-Coded Decimal) wanda yayi daidai da karatun wutar lantarki. Microcontroller yana karanta wannan ƙimar BCD. Sannan yana amfani da teburin nema don tantance waɗanne sassa (A-G) za a haskaka don kowane lamba don nuna lambar. Fil ɗin I/O na microcontroller, wanda aka haɗa ta hanyar resistors masu iyakance halin yanzu, suna tuƙa fil ɗin anode na LTD-5023AJD. Wasu fil ɗin I/O guda biyu, waɗanda aka haɗa zuwa masu sauya transistor, suna sarrafa fil ɗin cathode gama gari (14 da 13). Software ɗin yana saurin canzawa (haɗawa) tsakanin kunna Lamba 1 da Lamba 2, yayin aikawa da daidaitattun ƙirar anode don kowane lamba. Girman 0.56" yana ba da karatu bayyananne daga nisan benci na yau da kullun, kuma babban bambanci yana tabbatar da bayyana a ƙarƙashin hasken aikin. Ƙarancin amfani da wutar lantarki yana da fa'ida idan ma'aunin yana iya ɗauka.

11. Gabatarwar Ka'idar Fasaha

AlInGaP wani fili ne na semiconductor na III-V. Lokacin da aka yi amfani da ƙarfin wutar lantarki na gaba a kan haɗin p-n, ana shigar da electrons da ramuka cikin yankin aiki inda suke sake haɗuwa. Wannan tsarin sake haɗuwa yana sakin makamashi a cikin nau'in photons (haske). Takamaiman abun da ke ciki na Aluminum, Indium, Gallium, da Phosphide a cikin lattice crystal yana ƙayyade makamashin bandgap, wanda kai tsaye yana ƙayyade tsawon zango (launi) na hasken da aka fitar. Don launin Hyper Red, an daidaita bandgap don fitar da photons kusan 650 nm. Substrate na GaAs yana sha haske a wannan tsawon zango, don haka yawanci ana fitar da haske daga saman saman guntu. Sunan "Hyper Red" yana nuna launin ja mai zurfi, cikakke tare da babban inganci na haske.

12. Trends na Ci gaban Fasaha

Fasahar nuni na LED tana ci gaba da haɓaka. Duk da yake AlInGaP ya kasance babban kayan aiki don ingantattun LEDs ja da amber, trends sun haɗa da:
