Amateka ya LED: Kuva kuvumburwa kugeza Revolution

Inkomoko

Mu myaka ya za 1960, abahanga bakoze LED bashingiye ku ihame rya semiconductor PN ihuza. LED yateye imbere muri kiriya gihe yari ikozwe na GaASP kandi ibara ryayo ryaka ryari umutuku. Nyuma yimyaka hafi 30 yiterambere, tumenyereye cyane LED, ishobora gusohora umutuku, orange, umuhondo, icyatsi, ubururu nandi mabara. Nyamara, LED yera yo kumurika yakozwe nyuma ya 2000. Hano tumenyekanisha LED yera yo kumurika.

Iterambere

Isoko rya mbere ryumucyo LED ryakozwe na semiconductor PN ihuza ihame ryohereza urumuri rwatangiye mu ntangiriro ya za 1960. Ibikoresho byakoreshwaga muri kiriya gihe byari GaAsP, bisohora itara ritukura （λ P = 650nm), iyo moteri yo gutwara ari 20mA, flux flux ni ibihumbi bike gusa bya lumen, kandi imikorere ijyanye na optique ni 0.1 lumen / watt.

Mu myaka ya za 70 rwagati, ibintu Muri na N byatangijwe kugirango LED itange urumuri rwatsi （λ P = 555nm), itara ry'umuhondo （λ P = 590nm) n'umucyo wa orange （λ P = 610nm).

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

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

Mu 2000, LED yakozwe mubyambere yari mubice bitukura na orange （λ P = 615nm), naho LED ikozwe mubyanyuma iri mukarere kibisi （λ P = 530nm).

Amatara Yamateka

- 1879 Edison yahimbye itara ry'amashanyarazi;

- 1938 Itara rya Fluorescent ryasohotse;

- 1959 Itara rya Halogen ryasohotse;

- 1961 Itara rya sodium yumuvuduko mwinshi ryasohotse;

- 1962 Itara rya halide;

- 1969, itara rya mbere rya LED (umutuku);

- 1976 itara ryatsi rya LED;

- 1993 itara ry'ubururu LED;

- 1999 itara ryera rya LED;

- 2000 LED izakoreshwa mu gucana mu nzu.

- Iterambere rya LED nimpinduramatwara ya kabiri ikurikira amateka yimyaka 120 yumucyo mwinshi.

- Mu ntangiriro z'ikinyejana cya 21, LED, yatejwe imbere binyuze mu guhura gutangaje hagati y'ibidukikije, abantu, na siyansi, izahinduka agashya mu isi yoroheje kandi impinduramatwara y'icyatsi kibisi y'ingirakamaro ku bantu.

- LED izaba impinduramatwara ikomeye kuva Edison yahimbye itara.

Amatara ya LED ahanini afite ingufu nyinshi zera LED amatara imwe. Abakora amatara atatu ya mbere ya LED ku isi bafite garanti yimyaka itatu. Ibice binini birenze cyangwa bingana na lumens 100 kuri watt, naho uduce duto turenze cyangwa tungana na lumens 110 kuri watt. Ibice binini bifite urumuri ruri munsi ya 3% kumwaka, naho uduce duto dufite urumuri ruri munsi ya 3% kumwaka.

Amatara yo koga ya LED, amatara yo mu mazi ya LED, amatara ya LED, n'amatara yo hanze ya LED ashobora gukorwa cyane. Kurugero, itara rya watt 10 LED fluorescent irashobora gusimbuza itara risanzwe rya watt 40 cyangwa itara rizigama ingufu.
