Idan aka kwatanta da LED ɗin na'urar da aka saka a saman (SMD), nau'ikan cikin rami kamar wannan suna ba da fa'idodi a cikin ƙirar samfuri, haɗawa da hannu, da aikace-aikacen da ke buƙatar ƙarfin haɗin injiniya mafi girma ko bututun haske ta hanyar allon. Duk da haka, LED ɗin SMD gabaɗaya suna ba da damar sanya yawa mafi girma kuma sun fi dacewa da cikakkun layukan haɗawa ta atomatik, masu sauri na ɗauka da sanyawa.

10. Tambayoyin da Ake Yawan Yi (FAQs)

Q1: Shin zan iya tuƙa wannan LED a matsakaicin halinsa na 60mA akai-akai?

A1: A'a. Matsakaicin ƙimar Halin Gaba (60mA) yana don gajerun bugun jini kawai (≤0.1ms) a ƙaramin aikin aiki (≤10%). Matsakaicin halin gaba na DC na yau da kullun shine 20mA. Wuce wannan zai iya haifar da yawan zafi da lalacewa cikin sauri ko gazawa.

Q2: Me yasa akwai babban bambanci a cikin matsakaicin ƙarfin haske tsakanin LED ɗin kore (420mcd) da rawa (11mcd) a halin yanzu iri ɗaya na 10mA?

A2: Wannan da farko saboda kayan semiconductor daban-daban (InGaN don kore vs. AlInGaP don rawa) da hankalin ido na ɗan adam (lankwalin CIE), wanda ya kai kololuwa a yankin kore (~555nm). Ido ba shi da hankali ga tsawon tsawon rawa da aka fitar, yana haifar da ƙarancin ƙarfin haske da aka auna (a cikin mcd) don ƙarfin haske iri ɗaya.

Q3: Me zai faru idan na solder LED ba tare da kiyaye tsabtar 2mm daga gindin ruwan tabarau ba?

A3: Yin amfani da zafi kusa da ruwan tabarau na filastik ko gini zai iya haifar da narkewa, nakasa, ko canza launi. Hakanan yana iya canja wurin zafi mai yawa zuwa guntun LED ta hanyar igwa, mai yuwuwar lalata haɗin semiconductor ko haɗin igwa na ciki.

Q4: Ta yaya zan fassara lambobin kwandon lokacin yin oda?

A4: Lambobin kwandon (misali, KL & G10 don kore) suna ayyana kewayon da aka tabbatar na ƙarfin haske da tsawon tsawon rinjaye na LED ɗin da za ku karɓa. Ƙayyade kwandon yana ba ku damar zaɓar LED ɗin tare da aiki mai daidaito don aikace-aikacenku. Idan daidaiton launi ko haske yana da mahimmanci, ya kamata ku ƙayyade ƙunƙun kwandon kuma mai yiwuwa ku nemi bayanan gwaji.

Q5: Shin diode na kariya ta baya yana da mahimmanci a cikin da'irata?

A5: Takardar bayanai ta bayyana cewa ba a ƙera na'urar don aikin baya ba kuma ta ƙayyade halin baya (IR) a ƙarƙashin gwajin 5V. Duk da yake ƙaramin ƙarfin baya na lokaci-lokaci bazai haifar da gazawar nan take ba, ba a ba da shawarar ba. A cikin da'irori inda ƙarfin baya zai yiwu (misali, haɗin AC, kayan aikin inductive), kariya ta waje kamar diode na jerin ko diode mai karkatar da baya a kan LED yana da kyau don hana sanya karkatar da baya ga LED.
