Yanayi:Zana mai nuna yanayi don na'urar mai ɗaukar baturi mai ɗaukuwa.

Abubuwan Ɗauka a Zuciya:Ƙarancin amfani da wutar lantarki yana da mahimmanci. Zaɓin LED daga ƙananan bin ƙarfi (misali, R2: 140-180 mcd) na iya isa, yana ba da damar turawa shi a ƙarancin halin yanzu fiye da 20mA (misali, 10mA) don adana wutar lantarki yayin da har yanzu yana ba da isasshen gani. Faɗin kusurwar kallo na digiri 120 yana tabbatar da cewa ana iya ganin mai nuni daga kusurwoyi daban-daban ba tare da buƙatar LEDs da yawa ba. Zanen dole ne ya haɗa da juriya mai dacewa mai iyakancewa wanda aka ƙidaya bisa kewayon ƙarfin lantarki na baturi (wanda zai iya bambanta daga cikakken caji zuwa fitarwa) da V na LED_Fkewayon don tabbatar da daidaitaccen haske da guje wa wuce gona da iri.

13. Gabatarwa da Ka'idar Aiki

Diodes masu Fitowa Hasken (LEDs) na'urori ne na semiconductor waɗanda ke fitar da haske ta hanyar electroluminescence. Lokacin da aka yi amfani da ƙarfin gaba a kan junction p-n, electrons suna sake haɗuwa tare da ramuka a cikin yankin aiki (wanda ya ƙunshi AlInGaP a wannan yanayin), suna sakin makamashi a cikin nau'in photons. Takamaiman tsawon zango (launi) na hasken da aka fitar yana ƙayyade ta hanyar makamashin bandgap na kayan semiconductor. Ruwan tabarau na epoxy mai tsabta yana rufe die na semiconductor, yana ba da kariya ta injiniya, da kuma siffanta fitar da hasken.

14. Trends na Fasaha

Yanayin gabaɗaya a cikin fasahar SMD LED yana ci gaba zuwa ga mafi girman inganci na haske (ƙarin fitowar haske a kowace watt na shigar da wutar lantarki), ingantaccen bayyana launi, da rage girman kunshin yana ba da damar zane masu yawan girma. Hakanan akwai mai da hankali sosai kan haɓaka dogaro da aikin zafi don tallafawa ƙarin aikace-aikace masu ƙarfi. Bugu da ƙari, haɗawa tare da masu turawa masu hankali da tsarin sarrafawa don tasirin haske mai ƙarfi yana zama mafi girma. Bangaren da aka kwatanta a nan yana wakiltar cikakkiyar mafita, mai dogaro a cikin babban yanayin LED na nuni da sigina.
