Nyob rau hauv qhov chaw ntawm lub "qhov muag teev Ilyich" tuaj mus rau lub teeb LED

Cov tseem pheej chaw ntawm lub teeb hnub no, tsis muaj tsis ntseeg, ua LED teeb. Yog ib tug high-tech niaj hnub khoom, LED teeb maj los los hloov cov tsoos incandescent teeb, raws li zoo raws li ntau yam hom zog-saving pab kiag li lawm, uas nyob rau hauv lub domestic kev ua lag luam ntawm teeb pom kev zoo fixtures kuj kuj ntev los no.

Ib me ntsis keeb kwm

Lub teeb emission thaum lub sij hawm tso cai ntawm lub fais tam sim no los ntawm ib tug pn hlws ris ntawm ib tug semiconductor ntaus tau paub txij li thaum pib XX caug xyoo. Yog li, Henry Yauxej suav, lub inventor ntawm tus UK nyob rau hauv 1907, piav electroluminescence nyhuv los dua ib tug hluav taws xob tam sim no los ntawm ib tug khub ntawm hlau - Karbid Kremniya, nrog daj, ntsuab thiab txiv kab ntxwv ci nyob rau hauv qhov cathode. Zoo li cov thwmsim tau nqa tawm nyob rau hauv 1923 los ntawm cov Soviet paub txog Olegom Losevym (los ntawm txoj kev, mus txog thaum 70s los ntawm American zaum LED teeb yog zoo npe - «Losev teeb», tom qab lub npe yog tsis nco qab lawm). Tab sis tiag tiag yog hais tias qhov no foundations yog tsis muab, thiab yog li ntawd tsis soj ntsuam rau ob peb decades.

Nyob rau hauv 1961, nws tau patented invention yog lub infrared, thiab nyob rau hauv 1962 - ua hauj lwm nyob rau hauv lub teeb (liab) ntau yam ntawm cov LED. Tom qab, cov invention yog tsis tu ncua lawm. Feem, tsis thiab nws cov nqi. Yog li ntawd, nyob rau hauv 1968 nyob rau hauv LED qij, tus nqi yog hais txog $ 200, tab sis, vim hais tias ntawm lawv cov kev siv tswv yim yog heev tsawg.

Niaj hnub no, cov yaj yog siv txhua txhia qhov chaw. Ua li no, LEDs no muaj nyob nrog tag nrho cov nrov hom kaus mom: E27, E14, GU5.3, G53, GU10, G13.

Lub LED teeb zoo dua li ib txwm?

LED teeb muaj cov nram qab zoo:

• High luminous efficiency. Niaj hnub nimno cov piv txwv ntawm cov teeb pom kev zoo fixtures nyob rau hauv no parameter yog piv nrog hlau halide thiab sodium paug teeb.
• Tsis tshua muaj zog noj. Nws yog ob peb lub sij hawm tsawg dua cov pa lub teeb qhov chaw.
• Ntev pab lub neej. Nyob rau hauv lub chaw tsim tshuaj paus thiab teeb technology LED yuav nyob ntev li ntawm peb caug rau ib puas txhiab lub sij hawm. Cov nab npawb ntawm cov on-tawm mus, tsis ntau npaum li cas tej yam nyob rau hauv lub neej ntawm LEDs.
• High zog thiab kev co. Qhov no yog tiav vim lub fact tias muaj cov tsis nkag siab txhua yam kev nyuaj siab yam.
• Qhov tsawg inertia. Tsis zoo li lwm yam teeb, LED yuav luag tam sim ntawd pib ci ntawm tag nrho cov brightness. Dhau li ntawd, nws tsis yog ntshai ntawm lub hwj chim surges.
• High tej friendliness. Tsis zoo li cov zog-saving teeb, LEDs tsis tau muaj mercury los yog lwm yam teeb meem tshuaj.

Nws yog tsis yooj yim sua tsis hais qhov tseeb hais tias ntau thiab ntau cov neeg tsav tsheb pib mus thov txhua txhua xyoo LED teeb rau hauv lub tsheb. Muaj tib zoo raws li lub LEDs rau tsev neeg teeb pom kev zoo, lawv yog muab nrog rau ntau yam embodiments ntawm kaus mom (H1, h3, H7, h8, h10, etc.). Lawv yog ntsia tau rau hauv lub taub hau tsheb teeb, thiab tsis tsuas yog raws li pos huab, tab sis kuj raws li uas tsis muaj thiab siab beam.

Tej zaum qhov tsuas drawback, uas muaj ib tug LED teeb noob - tus nqi. Pheej Yig Heev LED (ll) nqi txog 500 rubles, thiab tus nqi ntawm cov feem ntau kim (chaw) yuav ncav cuag 5000. Txawm tias tag nrho cov, raws li lawv hais tias, yog tus txheeb ze. Txiav txim siab muab kev pab lub neej ntawm LED teeb, multiplied los ntawm tus xov tooj ntawm noj hluav taws xob yuav zoo yuav txawm ntau muaj txiaj ntsim tshaj rau kev siv ntawm cov pa lub teeb qhov muag teev.
