Yin bin waɗannan jagororin yana da mahimmanci don cimma yawan amfanin ƙasa da amincin dogon lokaci a fagen.

11. Tambayoyin da ake yawan yi (FAQ)

Q: Shin zan iya tuƙa guntu ja da kore a lokaci guda a 20mA kowanne?
A: Ee, amma dole ne ku yi la'akari da jimillar rushewar wutar lantarki. A 20mA da Vf na yau da kullun na 2.0V, kowane guntu yana rushe 40mW, jimillar 80mW. Wannan yana cikin matsakaicin matsakaicin ƙimar 75mW a kowane guntu, amma kusa da iyaka. Tabbatar da isasshen sanyaya PCB idan ana ci gaba da aiki a wannan matakin, musamman a cikin yanayin zafi mai girma.

Q: Menene bambanci tsakanin tsawon tsawon kololuwa da tsawon tsawon mai girma?
A: Tsawon tsawon kololuwa (λP) shine tsawon tsawon a mafi girman matsayi a cikin bakan fitarwa na LED. Tsawon tsawon mai girma (λd) shine tsawon tsawon guda ɗaya da idon ɗan adam ya gane, wanda aka lissafta daga ma'auni na launi akan ginshiƙi na CIE. λd ya fi dacewa don ƙayyadaddun launi a aikace-aikacen gani.

Q: Ta yaya zan ƙirƙiri hasken rawaya da wannan LED?
A: Ana ganin rawaya lokacin da aka gauraye hasken ja da kore. Ta kunna duka guntu ja da kore a lokaci guda kuma daidaita ƙarfinsu na dangi (misali, ta hanyar duhun PWM ko resistors na jerin daban-daban), zaku iya cimma inuwa daban-daban na rawaya, gami da amber.

Q: Shin diode na kariya na baya yana da mahimmanci?
A: Duk da yake LED ɗin zai iya jure ƙarfin lantarki na baya har zuwa 5V, ba a tsara shi don ci gaba da bias na baya ba. A cikin kewayawa inda za a iya yiwuwar ƙarfin lantarki na baya (misali, lodi na inductive, hot-plugging), aiwatar da kariya ta polarity ta baya na waje shine aikin ƙira mai hikima don haɓaka amincin.
