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

Q: Menene bambanci tsakanin tsayin kololuwa (596nm) da tsayin tsayin tsayin (584.5-594.5nm)?

A: Tsayin tsayin kololuwa shine wurin mafi girman ƙarfi a cikin fitarwar bakan. Tsayin tsayin tsayin an samo shi daga daidaitattun launi kuma yana wakiltar tsayin tsayin tsayin guda ɗaya na launin bakan tsantsa wanda ya dace da launin da LED ke gani. Suna da alaƙa amma ba daidai ma'auni na launi ba.

Q: Zan iya tuƙa wannan LED a 50mA akai-akai?

A: Yayin da matsakaicin matsakaicin matsakaici shine 50mA DC, ci gaba da aiki a wannan halin yanzu zai haifar da zafi mai yawa. Ainihin halin yanzu na aiki mai aminci ya dogara da yanayin yanayi da sarrafa zafi, kamar yadda ƙimar ɓarnawar wutar lantarki (120mW matsakaici) da lanƙwasa raguwa suka ƙaddara. A 25°C, 50mA tare da Vf na al'ada na 2.2V yana haifar da 110mW, wanda yana cikin iyakoki amma yana barin ɗan gefe kaɗan. Don aminci, yin aiki a ko ƙasa da yanayin gwaji na 20mA ya zama gama gari.

Q: Me ya sa resistor na jere ya zama dole ga kowane LED a layi daya?

A> Ƙarfin lantarki na gaba (Vf) yana da jurewa da kewayon binning (1.8V-2.4V). Ƙananan bambanci a cikin Vf tsakanin LEDs biyu da aka haɗa a layi daya zuwa tushen ƙarfin lantarki zai haifar da babban bambanci a cikin halin yanzu da kowanne yake ɗauka saboda lanƙwasa I-V mai ƙima na diode. Resistor na jere ga kowane LED yana sa halin yanzu ya zama ƙasa da hankali ga bambance-bambancen Vf, yana tabbatar da daidaitaccen haske.

11. Nazarin Shari'ar Ƙira mai Amfani

Yi la'akari da ƙira tarin pixel don cikakken launi a cikin alamar waje. Pixel na iya amfani da LED ɗaya ja, kore ɗaya, da LTL17KYV3JS (rawaya) LED ɗaya. Don cimma ma'auni na fari da hasken da ake nufi, halayen tuƙi don kowane launi na iya zama daban kuma ana sarrafa su ta hanyar PWM (Gyaran Faɗin Bugun Jini). Mai zane zai zaɓi LEDs daga kwandon ƙarfi da suka dace (misali, kwandon V ko W) don tabbatar da fitarwar tashar rawaya ta dace da ja da kore. Za a yi amfani da resistors masu iyakance halin yanzu daban-daban ga kowane LED, waɗanda aka ƙididdige su dangane da ƙarfin wutar lantarki da Vf na al'ada na LED daga lambar kwandon sa (misali, kwandon 2A: ~2.1V). Tsarin PCB zai kiyaye mafi ƙarancin 3mm daga ruwan tabarau don solder kuma ya ba da isasshen tazara don ɓarkewar zafi.

12. Gabatarwar Ƙa'idar Aiki

LTL17KYV3JS ya dogara ne akan kayan semiconductor na Aluminum Indium Gallium Phosphide (AlInGaP). Lokacin da aka yi amfani da ƙarfin lantarki na gaba a kan haɗin gwiwar PN, electrons da ramuka suna sake haɗuwa a cikin yanki mai aiki, suna sakin makamashi a cikin nau'in photons. Takamaiman abun da ke cikin yadudduka na AlInGaP yana ƙayyade ƙarfin bandgap, wanda kai tsaye yayi daidai da tsayin hasken da aka fitar—a wannan yanayin, rawaya (~596nm). Ruwan tabarau na epoxy yana aiki don kare mutuwar semiconductor, siffanta tsarin bazuwar zuwa kusurwar kallo na digiri 30, da kuma watsa hasken don kamanni iri ɗaya.

13. Trends na Fasaha

A cikin kasuwar LED ta alama, abubuwan da suka haɗa da ci gaba da haɓakar ingancin haske (lumens a kowace watt), yana ba da damar nunin haske ko ƙarancin amfani da wutar lantarki. Hakanan akwai motsi zuwa ƙarancin jurewar binning don duka launi da ƙarfi don ba da damar nunin manyan yanki marasa gani ba tare da bambance-bambancen launi ko haske ba. Yayin da na'urorin LED na ƙirar ƙira (SMD) suka mamaye sabbin ƙira don ƙanƙanta, LEDs ta cikin rami kamar kunshin T-1 sun kasance masu dacewa don aikace-aikacen da ke buƙatar ƙaƙƙarfan hawa na injiniya, sauƙin haɗa hannu, ko takamaiman halayen gani daga siffar ruwan tabarau na al'ada.
