Teeb pom kev lag luam Industrial Revolution
Vim li cas nws thiaj li hais tias lub xyoo pua 21st yuav coj mus rau lwm qhov kev hloov pauv hauv kev lag luam teeb pom kev zoo txij li Edison tau tsim lub teeb incandescent?
Tam sim no, cov khoom siv teeb pom kev zoo nyob rau hauv kev ua lag luam, txawm tias nws yog lub teeb incandescent, lub teeb fluorescent, los yog lub teeb tawm roj, yog cov khoom siv iav-plhaub hauv lub tshuab nqus tsev lossis lub xeev inflated. Lub teeb dawb-xeev dawb yog lub teeb dawb dawb huv, uas yog tsim los ntawm cov khoom siv semiconductor, tseem hu ua semiconductor white light devices, lossis LED light-emitting devices. Qhov tshwm sim ntawm high-brightness LEDs, tshwj xeeb tshaj yog qhov nce ntawm GaN-raws li xiav-ntsuab LEDs, tau revolutionized siv cov LEDs - los ntawm qhov taw qhia teeb rau teeb pom kev zoo. Lub invention ntawm lub dawb LED nyob rau hauv lub kawg ntawm lub xyoo pua xeem, lub teeb pom kev lag luam ntawm tib neeg tau nkag mus rau lub sij hawm tshiab. Vim yog lub lag luam loj loj ntawm tib neeg lub teeb pom kev hloov pauv thiab nws qhov tseem ceeb tsis kawg rau tib neeg txoj sia nyob thiab kev loj hlob, nws tsis yog exaggeration los ntseeg tias qhov tseem ceeb thiab kev cuam tshuam deb ntawm lub teeb pom kev tshwm sim tom ntej yuav tsis los ntawm qhov thib ob thev naus laus zis kiv puag ncig uas tshwm sim hauv ob centuries dhau los. (Lub hnub nyoog ntawm lub tshuab hluav taws xob thiab lub hnub nyoog ntawm microelectronics). Lub xyoo pua 21st tau coj mus rau lub sijhawm tshiab ntawm cov teeb pom kev zoo-xeev.
Teeb pom kev lag luam Industrial Revolution
Cov kws tshawb fawb kwv yees tias xyoo pua 21st yuav yog lub sijhawm uas microelectronics thiab optoelectronics ua haujlwm ua ke thiab ua haujlwm ua ke. Microelectronics thiab optoelectronics yog ob lub log uas cov ntaub ntawv thev naus laus zis nyob ntawm txoj kev loj hlob sai, thiab ob qho tib si yog qhov tseem ceeb. Thiab cov teeb pom kev zoo hauv lub xeev yog qhov ua tiav tshiab ntawm kev tshawb fawb thiab thev naus laus zis hauv lub xyoo pua 21st. Kev paub txog thaum ntxov ntawm semiconductor teeb pom kev zoo yuav coj cov teeb pom kev zoo ib txwm siv rau ntau tshaj 120 xyoo txij li Edison tau tsim lub teeb incandescent mus rau qhov kawg. Qhov no tsis yog tsuas yog ib qho kev hloov pauv loj hauv tib neeg lub teeb pom kev zoo thiab teeb pom kev lag luam ntau xyoo, tab sis kuj yog ib qho kev hloov pauv loj rau kev txhim kho tib neeg lub neej, uas yog ib qho txiaj ntsig loj rau kev vam meej ntawm tib neeg.
Vim tias muaj peev xwm loj hlob ntawm LEDs hauv cov teeb pom kev zoo, qee lub tebchaws thiab cheeb tsam tau tsim cov phiaj xwm kev loj hlob rau kev txhim kho LEDs. Nyiv tau siv "21st Century Light Plan" txij li xyoo 1998. Nws cia siab tias qhov kev ua haujlwm zoo ntawm cov LEDs dawb yuav ncav cuag 120lm / w hauv xyoo 2010, thiab los ntawm 2020, nws cia siab tias 50 feem pua ntawm cov roj teeb thiab tag nrho cov teeb fluorescent yuav yog. hloov. Tebchaws Asmeskas tseem tau nqis peev ntau ntawm 500 lab US las los tsim "Next Generation Lighting Source Project", lub hom phiaj los sib tw nrog Nyiv, Europe thiab Kaus Lim Qab Teb yav tom ntej 40 billion US dollars teeb pom kev lag luam. Nws npaj yuav siv LEDs nrog luminous efficiency ntawm 200lm los ntawm 2020. / w, deb tshaj qhov ua tau zoo ntawm ntau yam khoom siv teeb pom kev zoo tam sim no. Nws tau kwv yees hais tias los ntawm 2010, 55 feem pua ntawm cov teeb pom kev zoo thiab cov teeb fluorescent hauv Tebchaws Meskas yuav raug hloov los ntawm cov teeb hluav taws xob semiconductor, uas tuaj yeem txuag tau 35 billion US nyiaj hluav taws xob txhua xyoo. Tsis tas li ntawd, Kaus Lim Qab Teb, Sab Hnub Poob Tebchaws Europe, Taiwan thiab Tuam Tshoj av loj yog tag nrho cov viav vias los pib lawv tus kheej "kev npaj teeb pom kev zoo semiconductor." Ib yam li kev hloov cov raj xa hluav taws xob los ntawm cov transistors, nthwv dej ntawm cov teeb hluav taws xob semiconductor hloov cov teeb pom kev zoo ib txwm muaj yuav tsum tau nce thiab dhau mus. Nyob rau hauv lub ntsej muag ntawm kev ntxias loj ntawm lub lag luam semiconductor teeb pom kev zoo, peb lub teeb pom kev lag luam loj loj hauv ntiaj teb, General Electric, Philips, Osram thiab lwm lub tuam txhab loj tau koom tes nrog cov tuam txhab semiconductor los tsim cov tuam txhab teeb pom kev zoo semiconductor. Kev sib ntaus sib tua kom txeeb tau qhov siab tshaj plaws ntawm kev lag luam semiconductor teeb pom kev zoo tau pib thoob ntiaj teb. .
