Menene LED?
LED shine takaitaccen bayanin LIGHT EMITTING DIODE, wani bangaren da ke fitar da hasken monochromatic tare da kwararar wutar lantarki.
LEDs suna samar da masu zanen hasken wuta tare da sabbin kayan aikin fita don taimaka musu cimma mafi kyawun sakamako da haɓaka hanyoyin samar da hasken haske tare da tasirin ban mamaki waɗanda sau ɗaya a zahiri ba za a iya cimma su ba.LED mai inganci tare da ma'aunin CRI>90 wanda aka ƙididdige shi a 3200K - 6500K shima ya bayyana akan kasuwa.wadannan kwanan nanshekaras.
An inganta haske, kamanni, da ma'anar launi na fitilun LED har zuwa yanzu ana amfani da su don aikace-aikacen haske da yawa.Samfuran LED sun ƙunshi takamaiman adadin diodes masu fitar da haske waɗanda aka ɗora akan allon da'irar da aka buga (tsattsauran ra'ayi da sassauƙa) tare da na'urori masu aiki ko na yau da kullun.
Hakanan za'a iya ƙara na'urorin gani ko na'urorin jagorar haske dangane da filin aikace-aikacen don samun katako da haske daban-daban.Bambance-bambancen launuka, ƙaƙƙarfan girman da sassauƙan samfuran suna tabbatar da fa'idar yuwuwar ƙirƙira a yawancin aikace-aikace.
LEDs: yaya suke aiki?
LEDs su ne na'urorin semiconductor waɗanda ke canza wutar lantarki zuwa haske mai gani.Lokacin da aka kunna wutar lantarki (kai tsaye polarization), electrons suna motsawa ta hanyar semiconductor, kuma wasu daga cikinsu sun faɗi cikin ƙaramin ƙarfin ƙarfi.
A cikin tsarin, ana fitar da makamashin "ajiye" azaman haske.
Binciken fasaha ya ba da izinin cimma 200 Im/W don kowane babban ƙarfin lantarki na LED.Matsayin ci gaba na yanzu yana nuna cewa fasahar LED ba ta kai ga cikakkiyar damarta ba.
