10. Tambayoyin da ake yawan yi (Bisa Sigogi na Fasaha)

Q: Menene yawanci ƙarfin lantarki na aiki na wannan LED?
A: Daidaitaccen yanayin gwaji da yawancin ƙayyadaddun takardar bayanai ana bayar da su a 20mA. Ana iya aiki da shi har zuwa mafi girman ƙarfin lantarki na ci gaba na 30mA, amma fitowar haske da inganci ya kamata a tabbatar daga lanƙwan aiki, kuma sarrafa zafi ya zama mafi mahimmanci.

Q: Ta yaya zan fassara lambobin kwandon launi (misali, A0+2)?
A: Waɗannan lambobin sun dace da takamaiman yankuna akan ginshiƙin launi na CIE da aka ayyana a cikin takardar bayanai. Suna tabbatar da cewa ma'anar fari (dangantakar zafin launi da launi) yana cikin kewayon da aka sarrafa. Masu ƙira ya kamata su zaɓi kwandon asusun da suka dace da buƙatun daidaiton launin samfurinsu.

Q: Zan iya tuƙi wannan LED kai tsaye daga wadata 5V?
A: Ba tare da na'urar iyakance ƙarfin lantarki ba. Ƙarfin lantarki na gaba yawanci yana kusa da 3.0-3.4V. Haɗa 5V kai tsaye zai haifar da ƙarfin lantarki mai yawa, wanda ya wuce mafi girman ƙima kuma ya lalata LED. Resistor na jere ko direba na yau da kullun yana da mahimmanci.

11. Lamarin Aikace-aikace na Aiki

Yanayi: Ƙirar allon nuna yanayi don kayan aikin masana'antu.Ana amfani da LED ɗin fari da yawa don haskaka alamomin da ke wucewa. Don tabbatar da daidaiton haske, ya kamata a zaɓi LED ɗin daga kwandon asusun ƙarfin haske iri ɗaya (misali, W1). Ana iya ƙirar da'irar tuƙi mai sauƙi ta amfani da layin dogo na 12V da resistor na jere ga kowane LED. Ana ƙididdige ƙimar resistor kamar R = (V_supply - VF_LED) / I_LED. Ta amfani da VF na yau da kullun na 3.2V daga kwandon asusun 6 da ƙarfin lantarki da ake so na 20mA, R = (12V - 3.2V) / 0.02A = 440 Ohms (daidaitaccen resistor na 470 Ohm zai haifar da ~18.7mA, wanda ya yarda). Faɗin kusurwar kallo na digiri 120 yana tabbatar da cewa alamar tana haskakawa daidai ba tare da wurare masu zafi ba.

12. Gabatarwar Ƙa'idar Aiki

Wannan LED fari ne da aka canza phosphor. Tushen haske na asali shine guntu na semiconductor da aka yi da Indium Gallium Nitride (InGaN) wanda ke fitar da hasken shuɗi lokacin da aka yi masa bambanci na gaba (electroluminescence). Wannan hasken shuɗi wani ɓangare yana sha ta hanyar wani Layer na rufin phosphor na cerium-doped yttrium aluminum garnet (YAG:Ce) da aka yi amfani da shi akan guntu. Phosphor ɗin yana sha photons shuɗi masu ƙarfin kuzari kuma yana sake fitar da hasken rawaya mai ƙarancin kuzari ta hanyar aikin da ake kira photoluminescence. Sauran hasken shuɗi da ba a sha ba yana haɗuwa da hasken rawaya da aka fitar. Idon ɗan adam yana ganin wannan haɗuwar sassan bakan a matsayin hasken fari. Za a iya daidaita ainihin inuwa ko zafin launi na hasken fari ta hanyar daidaita abun da ke ciki da kauri na phosphor.

13. Trends na Fasaha

Ci gaban LED ɗin fari ya kasance tsakiyar juyin juya halin haske mai ƙarfi. Trends masu ci gaba suna mai da hankali kan haɓaka ingancin haske (lumens a kowace watt), inganta ma'anar nuna launi (CRI) don ƙarin haske na halitta, da kuma samun ingantaccen dogaro da tsawon rayuwa. Ci gaban fasahar phosphor, gami da amfani da ɗigon ƙididdigewa ko gaurayawan phosphor da yawa, suna ba da damar sarrafa ƙarin bakan fitarwa. Hakanan akwai yunƙurin zuwa ga ƙananan ƙira yayin da ake kiyayewa ko ƙara fitowar haske, kamar yadda aka gani a cikin micro-LEDs. Bugu da ƙari, haɗa kayan lantarki na sarrafawa kai tsaye tare da kunshin LED don aikace-aikacen haske mai hankali yanki ne na ci gaba da girma.
