Idan aka kwatanta da tsofaffin fasahohi kamar LED na jan Gallium Arsenide Phosphide (GaAsP), fasahar AlInGaP a cikin LTC-5836JG tana ba da ingantaccen ingantaccen aiki sosai, yana haifar da nunin masu haske don halin yanzu ɗaya, ko kuma haske iri ɗaya a ƙarancin wutar lantarki. Launin kore sau da yawa ana ganin ya fi dacewa don faɗaɗa kallo fiye da ja. Idan aka kwatanta da matrix-dot ko OLED na zane, wannan nunin sassa bakwai ya fi sauƙi, ya fi dacewa da kuɗi don aikace-aikacen lambobi kawai, kuma yawanci yana ba da haske mafi girma da dogon rayuwa, ko da yake ba shi da ikon haruffa ko zane.

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

Q: Menene manufar tsarin \"anode gama gari\"?

A: A cikin nunin anode gama gari, duk anodes na LEDs a cikin lamba an haɗa su tare zuwa fil guda ɗaya. Wannan yana ba da damar microcontroller don sarrafa wace lamba ke aiki ta hanyar samar da wutar lantarki (ta hanyar canji) ga wannan anode gama gari, yayin da ake sarrafa katod ɗin sashi ɗaya don kunna ko kashe takamaiman sassan. Wannan yana rage adadin fil ɗin microcontroller da ake buƙata sosai.

Q: Zan iya tuƙa wannan nunin tare da samar da 5V?

A: Ee, amma dole ne ka yi amfani da resistor mai iyakancewar halin yanzu a jere tare da kowane sashi. Misali, don cimma halin yanzu na gaba na 20 mA tare da VF na 2.6V da Vcc na 5V, ƙimar resistor zata zama R = (5V - 2.6V) / 0.02A = 120 Ohms. Dangantaccen resistor na 120Ω zai dace.

Q: Menene ma'anar \"an rarraba don ƙarfin haske\" ga ƙirara?

A: Yana nufin ana gwada nunin kuma a raba su cikin ƙungiyoyi (kwandon) bisa ga haskensu. Idan daidaiton haske cikakke yana da mahimmanci a duk raka'a na samfurin ku, yakamata ku ƙayyade kuma ku sayi na'urori daga kwandon ƙarfi ɗaya daga mai kaya.

Q: Ta yaya zan haɗa lambobi uku?

A: Za ku haɗa duk katod ɗin sassan da suka dace tare (misali, duk katod ɗin sashi \"A\" daga Lamba 1, 2, da 3 zuwa fil ɗin microcontroller ɗaya ta hanyar direba). Sannan kuma a jere kun kunna (samar da wutar lantarki ga) anode gama gari na Lamba 1, sannan Lamba 2, sannan Lamba 3, yayin da ake fitar da daidaitaccen tsarin sashi ga kowane lamba. Wannan zagayowar yana maimaitawa cikin sauri.

11. Ƙira mai Aiki da Amfani da Shari'a

Shari'a: Ƙirar Ƙididdigar Lokaci ta Lamba tare da Microcontroller.Mai ƙira yana ƙirar ƙididdigar lokaci. Suna amfani da LTC-5836JG don nuna mintuna da dakika (MM:SS). Sun haɗa layukan sashi 7 (A-G) da layukan colon/maki goma zuwa fitattun fil ɗin microcontroller ta hanyar resistors masu iyakancewar halin yanzu (wanda aka lissafa don 15 mA kowane sashi don daidaita haske da wutar lantarki). Fil ɗin anode gama gari guda uku (ɗaya ga kowane lamba na mintuna da biyu na dakika) an haɗa su zuwa microcontroller ta hanyar transistors na NPN waɗanda ke aiki azaman masu canza gefen ƙasa. Firmware na microcontroller yana gudanar da katsewar ƙididdigar lokaci a 1 kHz. A cikin aikin hidimar katsewa, yana kashe duk transistors na lamba, yana sabunta tsarin sashi don lamba ta gaba da za a nuna, yana kunna transistor ɗin lamba da ya dace, sannan ya matsa zuwa lamba ta gaba. Wannan tsarin haɗawa yana amfani da fil ɗin I/O na microcontroller 7+3=10 kawai don sarrafa nunin lamba 3, yana nuna ingantaccen amfani da albarkatu.

12. Gabatarwar Ka'idar Fasaha

LTC-5836JG ya dogara ne akan fasahar semiconductor na Aluminium Indium Gallium Phosphide (AlInGaP). Wannan shine semiconductor na III-V mai tazara kai tsaye. Lokacin da aka yi amfani da ƙarfin wutar lantarki na gaba a kan haɗin p-n, electrons daga yankin n-type da ramuka daga yankin p-type ana shigar da su cikin yankin aiki. Waɗannan masu ɗaukar caji suna sake haɗuwa, suna sakin makamashi a cikin nau'in photons (haske). Takamaiman abun da ke ciki na Al, In, Ga, da P a cikin lattice crystal yana ƙayyade makamashin tazara, wanda kai tsaye yayi daidai da tsayin rai (launi) na hasken da aka fitar. Don fitar da kore, an ƙera tazarar tazara kusan 2.2 zuwa 2.3 electron volts (eV). Amfani da tushen GaAs yana ba da samfuri na crystalline da ya dace don girma yadudduka na AlInGaP. Fuskar launin toka da sassa fari wani ɓangare ne na kunshin filastik, wanda ke aiki azaman mai watsawa da ruwan tabarau don siffanta fitar haske daga ƙananan guntuwar LED zuwa sassa iri ɗaya, masu ganewa.

13. Trends na Ci gaban Fasaha

Trend a cikin fasahar nunin LED yana zuwa ga ingantaccen aiki, haɗin kai mafi girma, da ƙirar siffofi masu yawa. Duk da yake nunin sassa bakwai masu hankali kamar LTC-5836JG sun kasance masu dacewa don aikace-aikacen lambobi kawai masu rauni, ana lura da trends da yawa. Na farko, motsi zuwa ga ƙarin ingantattun kayan aiki kamar Gallium Nitride (GaN) don shuɗi/kore/fari da ci gaba da gyara AlInGaP don ja/lemu/rawaya/kore. Na biyu, haɗa ICs direba kai tsaye cikin na'urar nunin (\"nunin hankali\") don sauƙaƙe ƙirar tsarin. Na uku, girma na kunshin na'urar da aka ɗora akan saman (SMD) akan nau'ikan rami don taron kai tsaye. A ƙarshe, matsin lamba na gasa daga madadin fasahohi kamar Organic LEDs (OLEDs) da Liquid Crystal Displays (LCDs), waɗanda ke ba da cikakken ikon zane a cikin siraran kunshin, ko da yake sau da yawa a farashi, haske, da wuraren rayuwa daban-daban. Nunin sassa bakwai na AlInGaP yana mamaye wani kusurwa mai ƙarfi inda sauƙinsa, ƙarfin ƙarfi, haske mai girma, da ƙarancin farashi suke fa'idodi masu yanke hukunci.
