Bisa ga bayanan fasaha, wannan LED ya dace da aikace-aikace da yawa. A cikin hasken gabaɗaya, ana iya amfani da shi a cikin kwararan fitila na LED, bututu, da fitilun panel. A cikin kayan lantarki na masu amfani, yana aiki azaman alamomin matsayi, hasken baya don nuni, ko hasken madannai. A cikin motoci na ciki, ana iya amfani da shi don hasken dashboard, fitilun dome, da hasken accent. Aikace-aikacen masana'antu sun haɗa da alamomin matsayin na'ura da hasken panel.

12. Gabatarwa da Ka'idar Aiki

LED diode ne na semiconductor. Lokacin da aka yi amfani da ƙarfin lantarki na gaba a kan haɗin gwiwar p-n, electrons da ramuka suna sake haɗuwa, suna sakin makamashi a cikin nau'in photons (haske). Tsawon raƙuman ruwa (launi) na hasken da aka fitar an ƙaddara shi ta hanyar bandgap na makamashi na kayan semiconductor. Fararen LED yawanci ana ƙirƙira su ta hanyar lulluɓe guntun LED shuɗi ko ultraviolet tare da kayan phosphor wanda ke ɗaukar wasu hasken farko kuma ya sake fitar da shi a tsayin raƙuman ruwa masu tsayi, wanda ke haifar da babban bakan da ake ganin shi azaman farin haske.

13. Trends na Fasaha

Masana'antar LED tana ci gaba da haɓakawa. Trends sun haɗa da ƙaruwar ingancin haske (ƙarin lumens a kowace watt), inganta fihirisar fitar da launi (CRI) da daidaiton launi, rage farashin kowane lumen, da haɓaka sabbin siffofi (ƙananan ƙira, substrates masu sassauƙa). Haka nan akwai mai da hankali sosai kan ingantaccen aminci da tsawon rayuwa a ƙarƙashin yanayin zafi da ƙarfin lantarki mafi girma. Hasken wayo, wanda ya haɗa da haɗin gwiwar sarrafawa da ji, wani muhimmin al'ada ne. Matsayin "Sake Dubawa 3" na takardar bayanin yana nuna wani wuri na farko a cikin wannan ci gaban fasaha mai gudana.
