Abuuritaanka LED-yada (diodes-ka iftiimiya iftiinka) wuxuu ahaa hannaan heerar badan leh oo ay ku lug leeyihiin wax-ku-darka saynisyahanno badan. Waa kuwan qaar ka mid ah waqtiyada taariikhiga ah ee muhiimka ah ee ikhtiraacida LED-yada:
Aragtida hore iyo tijaabooyinka:
1907:Saynis yahan British ah HJ Round ayaa markii ugu horeysay arkay in semiconductor-ka walxaha silicon carbide (SiC) uu iftiimiyo marka korontadu isticmaasho. Tani waxay ahayd ifafaale electroluminescence ee ugu horeysay ee la diiwaan geliyo ee qalabka semiconductor.
1920-yadii:Saynis yahanka Ruushka Oleg Losev ayaa sii darsay dhacdadan wuxuuna daabacay warqad ku saabsan mabaadi'da LED-yada 1927-kii, laakiin ma aysan soo jiidan dareenka baahsan waqtigaas.
Horumarinta LED-yada wax ku oolka ah:
1962:Nick Holonyak Jr., oo ah injineer ka shaqaynayay General Electric (GE) wakhtigaas, ayaa alifay LED-kii ugu horreeyay ee iftiinka muuqda (LED casaan). Holonyak waxaa loo yaqaan "Aabbaha LED-yada".
1972:M. George Craford, oo arday ka ah Holonyak, ayaa ikhtiraacay LED-kii ugu horreeyay ee huruud ah oo aad u hagaajiyay iftiinka LEDs-ka cas iyo orange-ka. Wuxuu sameeyay horumarin ku salaysan gallium nitride fosfooraska (GaAsP) walxaha si loo kordhiyo iftiinka LED-yada toban laab.
1970-meeyadii iyo 1980-meeyadii: Tignoolajiyada hormartay waxay horseedday abuuritaanka LED-yada midabo badan, oo ay ku jiraan cagaar, jaalle, iyo oranji.
Horumarka LED-ka buluugga ah:
1990-yadii:Saynis yahanada Hitachi iyo Nichia, gaar ahaan Shuji Nakamura, waxay alifeen LEDs buluug ah oo dhalaalaya. Tani waxay ahayd horumar wayn oo la isticmaalay agabka gallium nitride (GaN). Abuuritaanka LED-yada buluuga ah ayaa sameeyay bandhigyo midab buuxa ah iyo LEDs cad oo suurtagal ah.
2014:Shuji Nakamura, Isamu Akasaki, iyo Hiroshi Amano ayaa la guddoonsiiyay abaal marinta Nobel Prize ee Fiisigiska shaqadoodii ay ku lahaayeen LEDs buluug ah.
Horumarinta LED-yada cad:
Nalalka cad cad ayaa caadi ahaan la abuuraa iyadoo la isku darayo nalalka buluuga ah iyo fosfoorrada. Iftiinka buluugga ah ee LED-ka buluuga ah wuxuu kiciyaa fosfooraska, ka dibna wuxuu soo saaraa iftiin jaale ah, iyo isku dhafka labadaba waxay soo saaraan iftiin cad.
Horumarka tignoolajiyada LED-ka waxay keentay midabyo kala duwan oo LED ah oo aan ahayn cabbirka muuqda, laakiin sidoo kale ultraviolet iyo kala duwanaanta infrared. Maanta, LED-yada waxaa loo isticmaalaa codsiyo kala duwan, oo ay ku jiraan bandhigyada, nalalka, nalalka tilmaamayaasha, iyo isgaarsiinta.
