10. Misalin Amfani na Aiki

Yanayi: Ƙirar allon nuna yanayi don kayan aikin masana'antu.

Mai zane yana buƙatar LED alamar ja. Suna komawa wannan takardar bayanai don zaɓar LED tare da λp a cikin rarrabuwar tsawon zango na ja da ake so (misali, 625 nm) don tabbatar da daidaitaccen, launin ja mai haske a duk raka'o'in da ke kan allon. Sun lura cewa ƙayyadaddun kunshe sun ƙayyade jakar lantarki, don haka suka umurci sashin karɓarsu da su sarrafa kayan a tashar aiki mai aminci daga ESD. Bayanin adadin kunshe yana taimaka musu su tsara kayansu kuma su yi odar daidai adadin akwatunan ciki. Yayin shimfidar PCB, sun ƙirar tsarin kushin da ya dace da sawun LED kuma sun haɗa da taimakon zafi. A cikin umarnin haɗawa, sun ƙayyade bayanan reflow daga takardar bayanai ga mai kwangilarsu.

11. Gabatarwar Ka'idar Fasaha

LED diode ne na haɗin gwiwar p-n semiconductor. Lokacin da aka karkatar da shi gaba, electrons daga yankin n suna sake haɗuwa da ramuka daga yankin p a cikin yankin aiki, suna sakin makamashi a cikin nau'in photons (haske). Tsawon zango (launi) na hasken da aka fitar an ƙaddara shi ta hanyar tazarar bandgap na kayan semiconductor da aka yi amfani da su (misali, InGaN don shuɗi/kore, AlInGaP don ja/amber). "Kololuwar tsawon zango" shine takamaiman makamashin photon da aka fitar tare da mafi girman ƙarfi daga wannan tsari. Kunshen yana kare ƙwayar semiconductor mai laushi kuma ya haɗa da ruwan tabarau na epoxy wanda ke siffata fitar da haske da kare ƙwayar daga muhalli.

12. Trends na Masana'antu

Masana'antar LED na ci gaba da haɓaka zuwa ga ingantacciyar inganci (ƙarin lumens a kowace watt), ingantaccen nuna launi, da ingantaccen dogaro. Ƙananan ƙira ya kasance al'ada, yana ba da damar yin jeri mai yawa da sabbin siffofi. Har ila yau, ana ƙara ba da fifiko kan haske mai hankali da haɗin kai, yana buƙatar LED masu dacewa da da'irorin direba waɗanda ke goyan bayan dushewa da daidaita launi. Bugu da ƙari, bayyana sarrafa kaya da cikakkun takardun bayanai waɗanda za a iya karantawa da na'ura (kamar wannan tare da sarrafa bita bayyananne) suna zama ma'auni don tallafawa sarrafa kayan aiki ta atomatik da hanyoyin sarrafa inganci.
