8. Kwatancen Fasaha & Bambance-bambance

Idan aka kwatanta da tsofaffin fasahohi kamar daidaitaccen GaAsP ko LED ja GaP, fasahar AlInGaP a cikin LTS-4710AJD tana ba da ingancin haske mai yawa sosai. Wannan yana nufin zai iya samun mafi girman haske a igiyar lantarki ɗaya, ko haske ɗaya a ƙarancin lantarki sosai. Idan aka kwatanta da wasu LED "super-bright" masu ƙarancin lantarki sosai, an siffanta wannan na'urar kuma an ba da garantin daidaitawar sashi a ƙananan igiyoyin lantarki, wanda ke da mahimmanci don kamanni iri ɗaya a cikin tsarin bakwai sashi. Siffantarsa har zuwa 1 mA a kowane sashi takamaiman manufar ƙira ce wacce ba koyaushe ake samu ba a cikin nunin bakwai sashi na gabaɗaya.

9. Tambayoyin da ake yawan yi (Dangane da Ma'auni na Fasaha)

Q: Zan iya tuka wannan nuni kai tsaye daga fil ɗin microcontroller na 3.3V ko 5V?

A: A'a. Dole ne ka yi amfani da resistor mai iyakance igya ko takamaiman IC direba. Fil ɗin microcontroller ba zai iya samar da ko nutse da igiyar lantarki da ake buƙata don sashi da yawa lokaci guda ba kuma ba shi da ƙa'idar igiyar lantarki ta asali.

Q: Menene bambanci tsakanin kololuwar tsawon tsawon (656 nm) da tsawon tsawon da ya fi rinjaye (640 nm)?

A> Kololuwar tsawon tsawon ita ce madaidaicin ƙarfin bakan. Tsawon tsawon da ya fi rinjaye shi ne tsawon tsawon guda ɗaya na hasken monochromatic wanda zai dace da launin da ake gani. Ga LED ja, tsawon tsawon da ya fi rinjaye sau da yawa yana ɗan gajarta (mai launin lemu) fiye da kololuwar tsawon tsawon, kamar yadda idon ɗan adam ya gane.

Q: Ma'auni na ci gaba da igya yana raguwa sama da 25°C. Menene matsakaicin igiyar lantarki mai aminci a 70°C?

A> Ta amfani da ma'aunin raguwa na 0.33 mA/°C: Ƙaruwar zafin jiki = 70°C - 25°C = 45°C. Raguwawar igya = 45°C * 0.33 mA/°C = 14.85 mA. Matsakaicin igiyar lantarki mai aminci ta ci gaba ≈ 25 mA - 14.85 mA =10.15 mAa kowane sashi.

10. Lamarin Ƙira na Aiki

Yanayi:Ƙira na'urar ma'aunin zafi ta dijital mai ɗaukar baturi tare da nuni mai lamba 4 ta amfani da LTS-4710AJD, wanda tsarin 3.3V ke amfani da shi.

Aiwatarwa:Za a haɗa lambobi huɗu. Microcontroller zai sarrafa fil ɗin anode gama gari (ta hanyar sauya transistor) da layukan cathode sashi (ta hanyar fil ɗin GPIO, kowannensu yana da resistor na jerin). Don adana wutar lantarki, ana tuka sashi a matsakaicin igiyar lantarki na 2 mA. Ta amfani da haɗawa da yawa tare da aikin aiki na 1/4, igiyar lantarki ta nan take a kowane sashi yayin lokacin aiki zai kasance 8 mA (2 mA / 0.25 aikin aiki), wanda yake cikin ma'auni na kololuwa da na ci gaba. Karfin lantarki na gaba a ~8 mA yana kusan 2.2V (daga lanƙwasa I-V na yau da kullun). Ƙimar resistor mai iyakance igya zai kasance R = (3.3V - 2.2V) / 0.008A = 137.5 Ω. Za a yi amfani da daidaitaccen resistor 150 Ω, wanda zai haifar da ɗan ƙaramin igiyar lantarki na nan take na ~7.3 mA. Wannan ƙira yana cimma kyakkyawan haske yayin da yake haɓaka rayuwar baturi.

11. Gabatarwar Ka'idar Fasaha

LTS-4710AJD yana amfani da kayan semiconductor na AlInGaP (Aluminum Indium Gallium Phosphide) da aka girma akan wani abu na GaAs (Gallium Arsenide). AlInGaP kayan ne na bandeji kai tsaye wanda ya dace da fitar da haske a cikin bakan ja zuwa rawaya-lemu. Takamaiman abun da ke ciki na aluminum, indium, da gallium suna ƙayyade ƙarfin bandeji don haka tsawon tsawon da aka fitar (~656 nm don wannan na'urar). Kalmar "inganci" tana nufin ingantattun dabarun girma na epitaxial waɗanda ke rage lahani na crystal da inganta ingancin ƙididdiga na ciki—kashi na sake haɗuwar rami na electron da ke samar da photons. Abun da ba shi da gani na GaAs yana shan hasken da aka fitar, don haka ƙirar guntu tana amfani da dabarun don haɓaka fitar da haske daga saman saman, yana ba da gudummawa ga babban haske.

12. Trends na Fasaha

Trend a cikin LED na nuni yana ci gaba zuwa ga mafi inganci da ƙananan ƙarfin lantarki na aiki. Duk da yake AlInGaP ya balaga don ja/lemu/rawaya, sabbin kayan kamar InGaN (Indium Gallium Nitride) yanzu sun mamaye kasuwannin LED blue, green, da fari kuma ana haɓaka su don masu fitar da ja masu inganci. Don nunin bakwai sashi, trend yana zuwa ga haɗawa—saka direba IC har ma da microcontroller a cikin kunshin nuni don ƙirƙirar modules "mai hankali" waɗanda ke sauƙaƙa ƙirar tsarin. Bugu da ƙari, akwai turawa don ƙananan ƙananan ƙarfin lantarki na aiki don na'urorin IoT da na sawa masu ƙarancin wutar lantarki, da kuma inganta aikin zafi mai zafi don aikace-aikacen motoci da masana'antu.
