Koj puas tau xav dua"Thaum twg yog LED teeb pom kev tsim kho?"Zoo cov lus teb yuav ua rau koj xav tsis thoob ... coj nyob ib puag ncig rau ntau tshaj ib nrab xyoo! Qhov tseeb, kev ua haujlwm siv tau ntawm LED Technology tawm los ntawm 33 xyoo. Nws tau tsim los ntawm 33 xyoo General Fiber hlau Jr. Tom qab ntawd, ge hu ua nws"Cov khawv koob ib."Tiag tiag! Nyob rau sab nraum qab ntawm holonyak thawj lub cuab yeej yog sau: "khawv koob ib, gaasp."
Gaasp (Gallium arsenide phosphide) yog cov khoom siv semiconducting uas tau siv nyob rau hauv thawj LED. Raws li holonyak, gaasp yog "cov khoom uas tau los ua liab coj uas txhua tus pom ntawm cov elevators thiab txhua qhov chaw lwm." Nws ntxiv, "lawv tseem zaum ua rau lawv vim tias lawv thiaj li damn pheej yig!"
Holyak lees paub txog lub peev xwm ntawm LED teeb tshuab kev thev naus laus zis, "Yog tias kuv tuaj yeem tsim lub teeb hluav taws xob zoo thiab zoo txaus los ua ib tus nqi coj mus ua tus nqi." Nws zoo nkaus li kev xav tsis thoob li yog ntev npaum li cas nws tau coj LED thev naus laus zis coj los tuav hauv kev lag luam teeb pom kev zoo. Cia peb saib ib qho teeb meem luv luv ntawm qhov teeb tsa teeb pom kev zoo tau dhau mus dhau hauv xyoo dhau los txij li:
Thaum Ntxov LED thev naus laus zis (LED 1. 0=1960 s):
LEDs tau txais lawv pib raws li qhov ntsuas teeb pom kev rau cov txiag hluav taws xob rau cov khoom siv hluav taws xob thiab hluav taws xob hluav taws xob. Cov hnoos qeev ntxov tau ruaj khov, muaj cov lumens qis, thiab raws li tau muaj zog heev.
LEDs nce traction (LED 2. 0=1980 s):
Dhau lub sijhawm coj tau ua ci hlob thiab txhim khu kev qha ntau dua. Thib ob tiam LED thev naus laus zis suav nrog kev muaj peev xwm txoj hlua ntau cov coj mus rau hauv ib qho Circuit Court. Sij hawm dhau los, LEDs los ua ntau qhov haum rau kev siv sab nraum zoov. Raws li, lawv tau txais kev txhawb nqa los ntawm cov chaw hauv nroog uas yog hloov rau incandescent qhov muag teev nyob rau hauv lub teeb liab teeb. LEDs tseem pom kev vam meej tsis muaj kev vam meej hloov cov fluorescent qij thiab qe qe nyob rau hauv cov paib teeb pom kev zoo.
LED technology hnub no (LED 3. 0=21} sti caug xyoo):
Niaj hnub no LED Tshuab yog siv ntau yam rau kev ua lag luam, kev lag luam, thiab cov ntawv thov chaw nyob. LEDs 'lub peev xwm tau nce nyob thoob lub rooj tsavxwm: nce hauv lub neej: nce ntxiv hauv lub neej: nce hauv kev ci ntsa iab (kev ua tau zoo), thiab nce hauv kev ua haujlwm muaj zog. Kev siv cov cuab yeej siv tau zoo tshaj plaws tau ua rau kev tsim tawm ntawm kev lav, kev lag luam zoo tshaj plaws, thiab kev qhia ntawm tsoomfwv cov kev pabcuam thiab cov qauv.
