Ivumburwa rya LED (diode itanga urumuri) yari inzira ibyiciro byinshi birimo imisanzu yatanzwe nabahanga benshi. Dore ibihe bimwe byingenzi byamateka muguhimba LED:
Inyigisho za mbere nubushakashatsi:
1907:Umuhanga mu Bwongereza HJ Round yabanje kubona ko ibikoresho bya semiconductor material silicon karbide (SiC) bitanga urumuri iyo amashanyarazi akoreshejwe. Nibintu byambere byanditse kuri electroluminescence yibikoresho bya semiconductor.
1920:Umuhanga w’Uburusiya Oleg Losev yongeye kwiga kuri iki kibazo maze asohora urupapuro ku mahame ya LED mu 1927, ariko icyo gihe ntirwashimishije abantu benshi.
Gutezimbere LED zifatika:
1962:Nick Holonyak Jr., injeniyeri wakoraga muri General Electric (GE) icyo gihe, yahimbye urumuri rwa mbere rugaragara LED (LED itukura). Holonyak azwi nka "Se wa LED".
1972:M. George Craford, umunyeshuri wa Holonyak, yahimbye LED yambere yumuhondo kandi atezimbere cyane urumuri rwa LED itukura nicunga. Yakoze ibintu byinshi ashingiye kuri gallium nitride fosifore (GaAsP) kugirango yongere umucyo wa LED inshuro icumi.
1970 na 1980: Iterambere ry'ikoranabuhanga ryatumye hashyirwaho LED mu mabara menshi, harimo icyatsi, umuhondo, na orange.
Ubururu bwa LED Ubururu:
1990:Abahanga bo muri Hitachi na Nichia, cyane cyane Shuji Nakamura, bavumbuye LED yubururu-bwinshi. Iyi yari intambwe ikomeye ukoresheje ibikoresho bya gallium nitride (GaN). Ivumburwa rya LED yubururu ryakoze ibara ryuzuye ryerekana na LED yera birashoboka.
2014:Shuji Nakamura, Isamu Akasaki, na Hiroshi Amano bahawe igihembo cyitiriwe Nobel muri fiziki kubera akazi bakoze kuri LED y'ubururu.
Gutezimbere LED Yera:
LED yera isanzwe ikorwa muguhuza LED yubururu na fosifore. Itara ry'ubururu riva mubururu LED rishimisha fosifore, hanyuma igatanga urumuri rwumuhondo, kandi guhuza byombi bitanga urumuri rwera.
Iterambere mu buhanga bwa LED ryatumye amabara atandukanye ya LED atari murwego rugaragara gusa, ariko no muri ultraviolet na infragre. Uyu munsi, LED ikoreshwa muburyo butandukanye, harimo kwerekana, kumurika, amatara yerekana, n'itumanaho.
Ibikurikira bitangiza ibyiciro byibanze no gushyira mu bikorwa LED
Gutondekanya imbaraga zisohoka: 0.4W, 1.28W, 1.4W, 3W, 4.2W, 5W, 8W, 10.5W, 12W, 15W, 18W, 20W, 23W, 25W, 30W, 45W, 60W, 100W, 120W, 150W , 200W, 300W, n'ibindi.
Ibyiciro byashyizwe ahagaragara na voltage isohoka: DC4V, 6V, 9V, 12V, 18V, 24V, 36V, 42V, 48V, 54V, 63V, 81V, 105V, 135V, nibindi.
Gutondekanya ukurikije imiterere igaragara: ubwoko bubiri: PCBA yambaye ubusa hamwe na shell.
Gutondekanya ukurikije imiterere yumutekano: ubwoko bubiri: bwigunze kandi butigunze.
Gutondekanya kubintu byingufu: hamwe nimbaraga zo gukosora kandi nta mbaraga zifite.
Gutondekanya kubikorwa bitarimo amazi: birinda amazi kandi bidafite amazi.
Gutondekanya muburyo bwo kwishima: kwishima no kwishima hanze.
Gutondekanya ukurikije topologiya yumuzingi: RCC, Flyback, Imbere, Igice-Ikiraro, Cyuzuye-Ikiraro, Push-PLL, LLC, nibindi.
Gutondekanya muburyo bwo guhindura: AC-DC na DC-DC.
Gutondekanya kubikorwa bisohoka: guhora bigezweho, guhora voltage hamwe na voltage ihoraho hamwe na voltage ihoraho.
Gukoresha amashanyarazi ya LED:
Ikoreshwa kumatara, amatara yinama, amatara yijoro, amatara yo kurinda amaso, amatara yo hejuru ya LED, ibikombe byamatara, amatara yashyinguwe, amatara yo mumazi, gukaraba urukuta, amatara yumuriro, amatara yo kumuhanda, ibyapa byerekana amatara, amatara yumugozi, amatara, amatara yihariye, inyenyeri amatara, amatara yumuzamu, amatara yumukororombya, amatara yumwenda wumwenda, amatara yoroheje, amatara yumurongo, amatara yumukandara, amatara ya piranha, amatara ya fluorescent, amatara maremare maremare, amatara yikiraro, amatara yubucukuzi, amatara, amatara yihutirwa, amatara yameza, amatara, amatara yumuhanda, amatara azigama ingufu, amatara yimodoka, amatara ya nyakatsi, amatara yamabara, amatara ya kirisiti, amatara ya grille, amatara ya tunnel, nibindi.
Turi abanyamwuga batanga amashanyarazi mu Bushinwa, murakaza neza kubirebaurutonde rwibicuruzwa.
Nyamuneka saba izindi moderi, shyigikira ibicuruzwa byabigenewe.
