LED waa nooc ka mid ah semiconductor oo iftiimiya iftiinka markaad siiso xoogaa koronto ah.Habka wax soo saarkeeda iftiinku wuxuu ku dhow yahay nalka fluorescent iyo laambada soo daaya gaaska.Ilaysku ma laha fiilo, iftiinkeedana kuma dhaliyo kuleylinta fiilada, taas oo ah, ma dhaliso iftiin iyada oo u oggolaanaysa in hadda uu dhex socdo labada terminal.LED-ku waxa ay sii daayaan hirarka elektromagnetic-ka ah (oo ah inta jeer ee gariir aad u sarreeya), marka ay hirarkaasi gaadhaan in ka badan 380nm oo ay ka hooseeyaan 780nm, dhererka hirarka dhexda ayaa ah iftiin muuqda, iftiin muuqda oo ay arki karaan indhaha bini’aadamka.

Diodes-yada iftiinka soo saara waxa kale oo loo qaybin karaa nalalka monochrome-ka caadiga ah, laydhka-iftiinka-iftiinka-sare ee-dhalaalka,daabka-dhaleysyada-iftiinka-dhalaalka-sare-sare,-daabka-soo-saarka-ifalka-beddelka-midabka-soo-saarka,-iftiinka-soo-saarka iftiinka,-xakamaynta korantada. Diodes-baxa iftiinka, dareerayaasha iftiinka-bixiya infrared iyo caabbinta taban ee soo saarta iftiinka.

1. Tilmaamaha awoodda AC

Ilaa inta wareeggu ku xiran yahay khadka korontada ee 220V/50Hz AC, LED waa la shidi doonaa, taas oo muujinaysa in korontadu ay shidantahay.Qiimaha iska caabinta caabbinta xaddidan ee hadda jirta waa 220V/IF.

2. Iftiinka tilmaame beddelka AC

U isticmaal nalalka LED-ka wareeg ahaan si aad u hesho nalalka tilmaamaya nalka shidan.Marka uu furuhu go’o oo nalka uu bakhtiiyo, waxa uu hadda ka samaysan yahay loop dhex mara R, LED iyo nalka EL, LED-kuna wuu shidaa, taas oo ku habboon dadka inay ka helaan furaha gudcurka.Waqtigan xaadirka ah, hadda ku jira wareegga waa mid aad u yar, nalka iftiinkuna ma iftiimi doono.Marka uu shidmo, nalka waa shid, LED-kana waa la daminayaa.

3. Iftiinka godka korantada AC

Wareeg isticmaala laba-midab (cathode caadiga ah) LED sida iftiinka tilmaame ee meel AC.Korontada godka waxaa lagu maamulaa shideeyaha S. Marka LED-ka cas uu shido, godadku wax awood ah ma leh;marka laydhka cagaarani shidan yahay, godku waxa uu leeyahay awood.
