Mu myaka ya za 1960, abakozi ba siyansi n’ikoranabuhanga bakoze diode itanga urumuri rwa LED bakoresheje ihame rya semiconductor PN ihuza urumuri.LED yateye imbere icyo gihe yari ikozwe na GaASP, kandi ibara ryayo yari itukura.Nyuma yimyaka 30 yiterambere, bizwi cyane LED irashobora gusohora umutuku, orange, umuhondo, icyatsi, ubururu nandi mabara.Nyamara, LED yera yo kumurika yakozwe nyuma ya 2000. Hano, abasomyi bamenyeshwa LED yera kugirango bamurikire.

Inkomoko yumucyo ya mbere ya LED ikozwe muri semiconductor PN ihuza ihame ryohereza urumuri rwasohotse muntangiriro ya 1960.Ibikoresho byakoreshejwe icyo gihe ni GaAsP, itanga urumuri rutukura (λp = 650nm).Iyo ikinyabiziga cyo gutwara ari mA 20, flux flux ni ibihumbi bike gusa bya lumens, kandi efficant ya luminous ihwanye na 0.1 lumen / watt.

Mu myaka ya za 70 rwagati, ibintu Muri na N byatangijwe kugirango LED zitange urumuri rwatsi (λp = 555nm), itara ry'umuhondo (λp = 590nm) n'umucyo wa orange (λp = 610nm), kandi imikorere ya luminous nayo yariyongereye igera kuri 1 lumen / watt.

Mu ntangiriro ya za 1980, urumuri rwa LED rwa GaAlAs rwaragaragaye, bituma urumuri rwiza rwa LED rutukura rugera kuri lumens 10 / watt.

Mu ntangiriro ya za 90, ibikoresho bibiri bishya, GaAlInP, bitanga urumuri rutukura n’umuhondo, na GaInN itanga urumuri rwatsi nubururu, byatejwe imbere neza, biteza imbere cyane urumuri rwa LED.

Mu 2000, efficacy ya LEDs yakozwe nabambere yageze kuri lumens 100 kuri watt mukarere gatukura na orange (λp = 615nm), mugihe efficacy ya LEDs yakozwe nabanyuma mukarere kibisi (λp = 530nm) irashobora kugera kuri lumens 50./ watt.
