9. Tambayoyin da ake yawan yi (FAQ)

9.1 Menene bambanci tsakanin tsayin tsayi mai kololuwa da tsayin tsayi mai rinjaye?

Tsawon tsayi mai kololuwa (518 nm) shine wurin mafi girman ƙarfin radiyo a cikin bakan fitarwa. Tsawon tsayi mai rinjaye (525 nm) shine tsayin tsayi guda ɗaya da idon ɗan adam ke gani wanda ya dace da launin LED. Don LEDs k'ore, tsayin tsayi mai rinjaye sau da yawa ya fi tsayin tsayi mai kololuwa saboda siffar lanƙwasa amsawar gani na idon ɗan adam.

9.2 Shin zan iya tuka wannan LED a 25mA akai-akai?

Duk da yake matsakaicin ƙimar ƙarfin lantarki na gaba na ci gaba shine 25 mA, daidaitaccen yanayin gwaji da bayanan aiki na yau da kullun an ƙayyade su a 20 mA. Aiki a 25 mA na iya ƙara haske amma kuma zai haifar da ƙarin zafi, yana iya rage tsawon rayuwa da canza launi. Gabaɗaya ana ba da shawarar yin ƙira don tuka na yau da kullun na 20mA sai dai idan aikace-aikacen yana buƙatar ƙarin fitarwa na gefe kuma sarrafa zafi yana da kyau.

9.3 Yaya CAT, HUE, da REF suke aiki?

Waɗannan lambobin rarrabuwa ne. Ana rarraba LEDs bayan ƙirƙira bisa ga aikin da aka auna. CAT yana jera ƙarfin haske (misali, batutuwa masu haske suna samun lamba daban). HUE yana jera tsayin tsayi mai rinjaye (ƙarfafa yaduwar launi). REF yana jera ƙarfin lantarki na gaba. Ƙayyadaddun waɗannan matsayi yana ba masu ƙira damar zaɓar LEDs tare da halaye masu daidaito don aikace-aikacen da daidaito ke da mahimmanci, ko da yake yana iya shafar farashi da samuwa.

10. Ka'idar Aiki

Wannan LED ya dogara ne akan guntu na semiconductor na Indium Gallium Nitride (InGaN). Lokacin da aka yi amfani da ƙarfin lantarki na gaba wanda ya wuce ƙofar diode, ana shigar da electrons da ramuka cikin yanki mai aiki inda suke sake haɗuwa. A cikin wannan tsarin kayan, makamashin da aka saki yayin sake haɗuwa yayi daidai da photons a cikin ɓangaren k'ore na bakan gani (kusa da 518-525 nm). Takamaiman launi an ƙaddara shi ta hanyar daidaitaccen abun ciki na gami na InGaN. Resin na epoxy mai tsabta yana kare guntu, yana aiki azaman ruwan tabarau don siffanta fitar da haske, kuma yana iya ƙunsar phosphors ko masu watsewa (ko da yake don wannan sigar k'ore mai haske, yana bayyana).
