Audi LED headlights - ib puag ncig innovation
LED headlights txo cov roj noj. Yog vim li cas European Commission tau lees paub qhov kev daws teeb meem no.
Lub teeb pom kev zoo cuam tshuam rau kev lag luam ntawm tsheb. Piv txwv li: pa halogen low beam 
Yuav tsum muaj ntau tshaj 135 watts ntawm lub hwj chim, thaum Audi's LED headlights, uas yog ib qho tseem ceeb npaum li cas, noj tsuas yog li 80 watts. Lub European Commission tau tshaj tawm txoj kev tshawb fawb txog kev txuag roj npaum li cas nrog Audi's LED headlights. High beam, low beam thiab daim ntawv tso cai teeb pom kev zoo tau sim. Nyob rau hauv kaum NEDC xeem voj voog ntawm Audi A6, CO2 emissions raug txo los ntawm ntau tshaj ib gram ib kilometer. Raws li qhov tshwm sim, European Commission tau lees paub lub teeb taub hau LED ua qhov kev daws teeb meem tshiab los txo qis COXNUMX emissions. Audi yog thawj cov chaw tsim khoom tau txais cov ntawv pov thawj zoo li no.
LED nruab hnub khiav teeb ua lawv qhov debut hauv Audi A8 W12 rov qab rau xyoo 2004. Nyob rau hauv 2008, R8 kev ua si tsheb tau los ua lub ntiaj teb thawj lub tsheb nrog tag nrho LED headlights. Niaj hnub no, qhov kev daws teeb meem siab tshaj no muaj nyob rau hauv tsib lub qauv: R8, A8, A6, A7 Sportback thiab A3.
Audi siv cov teeb LED sib txawv ntawm cov qauv sib txawv. Piv txwv li, A8 siv cov blocks nrog 76 LEDs. Hauv Audi A3, txhua lub teeb taub hau muaj 19 LEDs rau cov kab qis thiab siab. Lawv tau ua tiav los ntawm kev tsav tsheb txhua lub caij ntuj sov thiab lub kaum sab xis teeb pom kev zoo, nrog rau cov teeb pom kev hauv nruab hnub nrig, lub teeb pom kev thiab teeb pom kev zoo. LED headlights tsis yog tsuas yog siv tau zoo xwb, tab sis kuj muab kev nyab xeeb thiab kev nplij siab. Ua tsaug rau cov xim kub ntawm 5,5 txhiab Kelvin, lawv lub teeb zoo ib yam li nruab hnub nrig thiab yog li tsis ua rau tus neeg tsav tsheb lub qhov muag. Diodes tsis muaj kev saib xyuas thiab muaj lub neej ntev sib npaug ntawm lub tsheb.
