Ko da yake ba koyaushe ake bayyana su a sarari ba, sigogi a cikin takardar bayanai suna ba da damar kwatanta da samfuran da ke fafatawa. Ana iya fahimtar fa'idodi daga babban ingancin haske (lumens a kowace watt), ƙarancin juriya na zafi, faɗin kewayon zafin aiki, ko ƙayyadaddun ƙayyadaddun kwandon launi, duk suna ba da gudummawa ga mafi kyawun aiki, inganci, ko sassaucin ƙira.

11. Tambayoyin da ake yawan yi (FAQ)

Tambayoyin gama gari dangane da sigogi na fasaha sun haɗa da: "Ta yaya zan zaɓi mai iyakance halin yanzu?" (ta amfani da Vf da ƙarfin lantarki), "Me ya sa LED dina ya yi duhu fiye da yadda ake tsammani?" (sau da yawa saboda yawan zafi ko kuskuren halin yanzu), "Zan iya fitar da wannan LED tare da tushen ƙarfin lantarki?" (ba a ba da shawarar ba tare da sarrafa halin yanzu ba), da "Har yaushe wannan LED zai daɗe?" (wanda aka ayyana ta hanyar lanƙwasa kula da lumen, yawanci ƙimar L70 ko L50 tana nuna lokacin zuwa 70% ko 50% na fitowar haske na farko).

12. Lamuran Amfani na Aiki

Dangane da ƙayyadaddun LED na gama gari, yuwuwar aikace-aikace na iya haɗawa da hasken gabaɗaya (kwan fitila, panel), hasken mota (ciki, sigina), hasken baya don nuni da alamomi, fitilun nuni akan na'urorin lantarki na mabukaci, da takamaiman aikace-aikace a cikin aikin gona ko na'urorin likita, dangane da takamaiman tsawon zango da ƙarfin fitarwa.

13. Ka'idar Aiki

Diodes masu fitar da haske (LEDs) na'urorin semiconductor ne waɗanda ke fitar da haske ta hanyar electroluminescence. Lokacin da aka yi amfani da ƙarfin lantarki na gaba a kan mahadar p-n, electrons suna haɗuwa tare da ramuka, suna sakin makamashi a cikin nau'in photons. Tsawon zango (launi) na hasken 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). LED farare yawanci ana ƙirƙira su ta hanyar lulluɓe guntun LED shuɗi da phosphor rawaya, wanda ke canza wasu hasken shuɗi zuwa rawaya, wanda ke haifar da cakuda da ake ganin fari.

14. Trends na Fasaha

Masana'antar LED tana ci gaba da haɓakawa. Trends sun haɗa da haɓaka ingancin haske, rage farashin kowane lumen, inganta nuna launi don ingantaccen farin haske, da haɓaka sabbin sifofi kamar fakitin ma'auni na guntu (CSPs). Hakanan akwai mai da hankali sosai kan haske mai hankali da haske mai da hankali kan ɗan adam, haɗa sarrafawa don zafin jiki da daidaita ƙarfi. Ƙananan ƙira da mafi girman yawan wutar lantarki suna ci gaba da tura iyakokin fasahar gudanar da zafi.
