• Sarrafa Zafi:Duk da cewa rushewar wutar lantarki ƙanƙanta ne, tabbatar da isasshen iska idan an yi amfani da nunin da yawa a cikin ƙunƙuntaccen sarari, musamman kusa da ƙarshen kewayon zafin aiki.
• Kusurwar Dubawa:Takardar bayanan ta nuna "Kusurwar Duba Mai Faɗi." Ya kamata a yi la'akari da wannan yayin ƙirar injiniya don tabbatar da cewa an daidaita nuni daidai ga mai amfani na ƙarshe.

8. Tambayoyin da ake yawan yi (Bisa Ƙayyadaddun Fasaha)

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

A: Mai yiwuwa, amma dole ne ku duba ƙarfin lantarki na gaba. Yawanci V_Fshi ne 2.6V. Fil ɗin 3.3V na iya samar da 3.3V - 2.6V = 0.7V kawai a kan resistor mai iyakancewar halin yanzu, yana iyakance matsakaicin halin yanzu don haka haske. Gabaɗaya yana da aminci don amfani da da'irar direba ko mafi girman ƙarfin wadata don gefen anode.

Q: Menene bambanci tsakanin tsawon zango mai kololuwa da tsawon zango mafi rinjaye?

A: Tsawon zango mai kololuwa (565nm) shine kololuwar jiki na bakan hasken da aka fitar. Tsawon zango mafi rinjaye (569nm) shine tsawon zango guda ɗaya na hasken monochromatic wanda zai bayyana yana da launi ɗaya da fitowar LED ga idon ɗan adam. Tsawon zango mafi rinjaye ya fi dacewa don fahimtar launi.

Q: Ta yaya zan cimma daidaiton haske a duk kashi?

A> Yi amfani da ƙimar resistor mai iyakancewar halin yanzu iri ɗaya ga duk kashi. Ƙimar daidaitawar ƙarfin haskakawa na ciki (2:1 matsakaici) yana tabbatar da cewa ko da tare da halin yanzu na tuƙi iri ɗaya, kashi ba za su bambanta cikin haske fiye da sau biyu ba. Don mahimman aikace-aikace, zaɓi nunin daga kwandon ƙarfi ɗaya.

9. Ka'idar Aiki

LTD-5307AG yana aiki akan ka'idar electroluminescence a cikin haɗin P-N semiconductor. Lokacin da aka yi amfani da ƙarfin lantarki na gaba wanda ya wuce kofa na diode (kusan 2.1-2.6V don wannan na'urar GaP), electrons daga kayan N-type suna sake haɗuwa tare da ramuka daga kayan P-type a cikin yankin raguwa. A cikin LED na Gallium Phosphide (GaP), wannan taron sake haɗawa yana sakin makamashi a cikin nau'in photons (haske) tare da tsawon zango daidai da ƙarfin bandgap na kayan, wanda ke cikin yankin kore na bakan. Abin da ke ƙarƙashin GaP mai gani yana ba da damar ƙarin wannan hasken da aka samar a ciki don tserewa, yana ba da gudummawar inganci mafi girma. Ana haskaka takamaiman kashi ta hanyar zaɓin amfani da karkatar da gaba ga anode na kashin da ake so yayin da ake kafa ƙasa katod gama gari na lambar da ta dace.

10. Mahallin Fasaha da Trends

LTD-5307AG yana wakiltar fasaha mai girma kuma abin dogaro bisa ga kayan GaP. Duk da cewa sabbin fasahohin nuni kamar OLEDs, micro-LEDs, da ingantattun LED na tushen InGaN suna ba da fa'idodi dangane da gamut launi, inganci, da ƙuduri don zane-zane masu rikitarwa, na'urorin nuni na LED 7-kashi na gargajiya kamar wannan sun kasance masu dacewa sosai. Fa'idodinsu sun haɗa da sauƙaƙan sarrafawa, babban abin dogaro da tsawon rai, kyakkyawan haske da bambanci, faɗin kewayon zafin aiki, da ƙaramin farashi. Su ne zaɓi mafi kyau don aikace-aikace inda kawai lambobi ko bayanan haruffa masu sauƙi ke buƙatar nunawa a sarari kuma abin dogaro a ƙarƙashin yanayi daban-daban, kamar a cikin sarrafa masana'antu, na'urorin likita, dashboard na mota (don ayyuka na biyu), da kayan aikin gida. Trend a cikin wannan ɓangaren yana zuwa ga inganci mafi girma (ƙarin fitowar haske kowane mA), ƙananan ƙarfin lantarki na gaba don zama mafi dacewa da dabaru na zamani masu ƙarancin ƙarfin lantarki, da yuwuwar ƙananan girman kunshin yayin kiyayewa ko inganta karantawa.
