Ana ƙididdige ƙimar resistor ta amfani da dabara R = (Vcc - VF) / IF, inda VF shine ƙarfin gaba (yi amfani da matsakaicin 2.6V don aminci), Vcc shine ƙarfin wutar lantarki, kuma IF shine ƙarfin gaba da ake so (kada ya wuce 25 mA ci gaba).Da'irar Direba: A matsayin na'urar katod gama gari, yana da kyau a tuka shi ta hanyar microcontroller ko IC mai ɓoyewa wanda zai iya zubar da ƙarfi (ja katod gama gari ƙasa) da kuma samar da ƙarfi ga anod ɗin sassa daban-daban. Haɗa lambobi da yawa fasaha ce ta gama gari, amma wannan na'urar lamba guda ce.Kusurwar Dubawa: Takardar bayanin ta yi iƙirarin cewa tana da faɗin kusurwar dubawa, wanda ke da amfani ga allunan da ake duba daga wuraren da ba su da axis.

9. Kwatancen Fasaha

Idan aka kwatanta da tsofaffin fasahohi kamar daidaitattun GaAsP ko GaP jan LED, fasahar AlInGaP a cikin LTS-5003AJD tana ba da ingancin haske mai girma sosai, yana haifar da haske mafi girma don irin wannan ƙarfin tuƙi. Idan aka kwatanta da madadin zamani, mabambantan sa sune takamaiman tsawon lamba 0.56-inch, jan launi mai inganci, da tsarin katod gama gari. Nunin da ke da manyan lambobi, launuka daban-daban (misali, kore, rawaya), ko tsarin anod gama gari za su bi buƙatun ƙira daban-daban.

10. Tambayoyin da ake yawan yi (Bisa Siffofin Fasaha)

Q: Menene manufar fil katod gama gari biyu (3 da 8)?

A: An haɗa su a ciki. Samun fil biyu yana ba da mafi kyawun rarraba ƙarfi da kwanciyar hankali na injiniya, kuma yana ba da sassauci a cikin shimfidar PCB.

Q: Shin zan iya tuka wannan nuni kai tsaye daga fil ɗin microcontroller na 5V?

A: A'a. Dole ne ka yi amfani da resistor mai iyakance ƙarfi. Misali, tare da wadataccen wutar lantarki na 5V da manufar IF na 20mA, kuma ta amfani da VF(max)=2.6V, ƙimar resistor zata zama (5V - 2.6V) / 0.02A = 120 Ohms. Koyaushe tabbatar da ikon samar da ƙarfin fil ɗin microcontroller.

Q: Me ake nufi da "ƙarancin buƙatun wutar lantarki" a ƙididdiga?

A: A matsakaicin wurin aiki na 10mA kowane sashi da VF=2.6V, wutar lantarki kowane sashi shine 26 mW. Haskaka dukkan sassa 7 (da ƙari na Ɗesimal) zai ja 80mA gabaɗaya, yana cinye kusan 208 mW, wanda yake da ƙasa don nuni mai haske.

Q: Yadda ake auna ƙarfin haske?

A: Kamar yadda aka lura, ana auna shi tare da firikwensin da tacewa wanda ke kusantar da lanƙwasa amsawar ido na CIE photopic, yana tabbatar da cewa ma'aunin yana da alaƙa da hasashen haske na ɗan adam.

11. Yanayin Amfani na Aiki

Yi la'akari da ƙirar sauƙi na tachometer na lambobi don mota. Microcontroller yana auna mitar bugun jini daga firikwensin. Ana canza wannan ƙimar mitar zuwa RPM. Za a iya nuna mafi mahimmancin lamba guda na RPM (misali, lambar "dubu") ta amfani da LTS-5003AJD. Microcontroller zai ƙididdige waɗanne sassa (A-G) za a haskaka don samar da wannan lambar, sannan ya tuka katod gama gari ƙasa kuma ya saita fil ɗin anod da suka dace sama ta hanyar resistors masu iyakance ƙarfi. Babban haske yana tabbatar da karantawa a cikin yanayin aikin.

12. Ka'idar Aiki

Na'urar tana aiki bisa ka'idar electroluminescence a cikin haɗin p-n na semiconductor. Lokacin da aka yi amfani da ƙarfin gaba wanda ya wuce ƙarfin kunna diode a kan sashi (anod tabbatacce, katod mara kyau), electrons da ramuka suna sake haɗuwa a cikin yanki mai aiki na kayan semiconductor na AlInGaP. Wannan sake haɗuwa yana sakin makamashi a cikin nau'in photons, yana samar da hasken ja. Takamaiman haɗin gawa na AlInGaP yana ƙayyade ƙarfin bandgap, wanda kai tsaye yana ayyana tsayin raƙuman ruwa (launi) na hasken da aka fitar. Sassa bakwai LED ne masu zaman kansu waɗanda aka tsara su cikin tsarin siffa takwas; ta hanyar zaɓin ƙarfafa haɗuwa daban-daban na waɗannan sassa, ana iya samar da duk lambobi daga 0 zuwa 9.

13. Trends na Fasaha

Duk da yake nunin sassa bakwai sun kasance mafita mai ƙarfi da inganci don karatun lambobi, babban yanayin a cikin fasahar nuni yana zuwa ga haɗin kai mafi girma da sassauci. Ƙungiyoyin lambobi da yawa tare da masu sarrafa haɗin kai (I2C, SPI) suna zama gama gari, suna rage adadin fil ɗin microcontroller da kayan aikin software. Bugu da ƙari, nunin matrix-dot da OLEDs suna ba da damar haruffa da na hoto a cikin irin wannan kunshin. Duk da haka, don aikace-aikacen da ke buƙatar kawai sauƙi, mai haske, amintacce, da lamba mai inganci, LED na sassa bakwai masu rarrabuwa kamar LTS-5003AJD, musamman waɗanda ke amfani da kayan aiki masu inganci kamar AlInGaP, suna ci gaba da zama zaɓi mai dacewa kuma mafi kyau saboda sauƙinsu, dorewa, da kyakkyawan bambance-bambance a cikin yanayin haske daban-daban.
