Lub teeb ua haujlwm nruab hnub - halogen, LED lossis xenon? - qhia
Ntxiv rau qhov paub zoo xenon nruab hnub khiav teeb, ntau thiab ntau cov modules hauv LED thev naus laus zis tau tshwm sim hauv khw. Tsis tsuas yog lawv siv lub zog tsawg, tab sis lawv kuj siv tau ntev dua li cov teeb halogen lossis xenon. Lawv ua haujlwm txog li 10 teev.
Kev tsim kho tshiab ntawm LED thev naus laus zis ua rau nws muaj peev xwm emit ntau lub teeb nrog tsawg zog siv. Ntxiv nrog rau kev nyab xeeb thiab kev lag luam roj ntau dua, LED teeb txhim kho lub tsheb zoo nkauj los ntawm kev muab nws tus kheej kov.
LED lub teeb ua haujlwm nruab hnub - lawv lub zog txuag
Tomasz Supady, kws tshaj lij ntawm Philips Automotive Lighting hais tias "LED thev naus laus zis tuaj yeem txo qis kev siv roj ntau," - Piv txwv li, ib txheej ntawm ob lub teeb halogen siv 110 watts ntawm lub zog, ib txheej txheej txheem nruab hnub khiav teeb los ntawm 32 txog 42 watts, thiab ib txheej ntawm LEDs tsuas yog 10 watts. Yuav kom tsim tau 110 watts ntawm lub zog, 0,23 litres roj av ib 100 km yuav tsum tau.
Tus kws tshaj lij piav qhia tias nyob rau hauv cov ntaub ntawv ntawm LED nruab hnub khiav teeb, tsim 10 watts ntawm lub zog ib 100 km nqi peb ib tug measly 0,02 litres roj av. Lub teeb taub hau niaj hnub, muaj nyob rau hauv cov khw muag khoom tsheb, tsis muaj teeb meem rau cov neeg siv vim tsis siv neeg hloov mus rau thiab tawm. Cov khoom siv LED muaj qhov ruaj khov dua piv rau xenon lossis halogen - lawv ua haujlwm 10 teev, uas sib haum rau 500-000 mais ntawm qhov ceev ntawm 50 km / h. Qhov nruab nrab, LEDs kav ntev li 30 npaug ntev dua li cov H7 qhov muag teev uas siv hauv lub teeb taub hau.
LED modules tso tawm lub teeb nrog cov xim kub heev (6 Kelvin). Xws li lub teeb, ua tsaug rau nws cov xim ci, dawb, ua kom lub tsheb uas peb tsav tau twb pom ntawm txoj kev los ntawm kev deb mus rau lwm tus neeg siv txoj kev. Rau kev sib piv, xenon teeb emit teeb nyob rau hauv thaj tsam ntawm 4100-4800 Kelvin.
Ceev faj ntawm lub teeb cuav
Thaum muas lub teeb ua haujlwm nruab hnub, koj yuav tsum tau them sai sai rau seb lawv puas muaj daim ntawv tso cai, i.e. tso cai siv cov khoom hauv lub tebchaws ntawd.
Tomasz Supady piav qhia tias "Nrhiav E-embossed teeb, zoo li E1," piav qhia Tomasz Supady. - Tsis tas li ntawd, lub teeb ua haujlwm nruab hnub raug cai yuav tsum muaj cov ntawv RL ntawm lub teeb. Txhawm rau kom tsis txhob muaj teeb meem, koj yuav tsum yuav cov khoom siv teeb pom kev zoo los ntawm cov tuam txhab ntseeg siab.
Cov kws tshaj lij tau hais tias koj yuav tsum tsis txhob yuav lub teeb uas muaj teeb meem nrog kev sib tw hauv online. Ib tug kws tshaj lij los ntawm Philips piav qhia tias tus nqi txaus nyiam ntawm xenon lossis LED teeb yuav tsum ua rau peb xav tsis thoob.
Los ntawm kev txhim kho cov khoom cuav, feem ntau ua hauv Suav teb, peb pheej hmoo poob daim ntawv pov thawj rau npe, vim tias lawv yuav luag tsis pom zoo. Tsis tas li ntawd, qhov tsis zoo ntawm lub teeb dramatically txo nws cov durability. Fake headlights feem ntau muaj teeb meem nrog kev xau thiab tsis muaj cov cua kub zoo. Cov teeb zoo li no tsuas yog ci dua, thiab ntxiv rau, lawv tuaj yeem cuam tshuam cov neeg tsav tsheb taug kev los ntawm kev sib txawv.
Txhim kho cov teeb ua haujlwm nruab hnub
Lub teeb ua haujlwm nruab hnub yuav tsum yog dawb. Yog tias peb tig tus yuam sij rau hauv qhov hluav taws xob, lawv yuav tsum tig rau nws. Tab sis lawv kuj yuav tsum tau tua yog tias tus neeg tsav tsheb tig rau ntawm txoj kab hluav taws xob, lub teeb siab lossis lub teeb pos huab.
Thaum txhim kho lawv nyob rau hauv pem hauv ntej ntawm lub tsheb, nco ntsoov tias lawv yuav tsum muaj tsawg kawg yog 25 cm los ntawm hauv av thiab tsis siab tshaj 150 cm. Qhov kev ncua deb ntawm lub modules yuav tsum muaj tsawg kawg yog 60 cm. 40 cm ntawm sab contour ntawm lub tsheb.
Cov khoom muaj nqi
Tus nqi rau cov teeb ua haujlwm nruab hnub sib txawv. Cov teeb nruab hnub nruab hnub raug nqi ib ncig PLN 50. Tus nqi rau LEDs yog siab dua. Lawv nyob ntawm qhov zoo ntawm cov diodes siv hauv lawv (cov ntawv pov thawj, kev pom zoo) thiab lawv qhov ntau.
hauv module. Piv txwv li: hwm qauv nrog 5 LEDs nqi ib ncig PLN 350.
Zoo paub
Raws li European tus qauv ECE R48, txij Lub Ob Hlis 7, 2011, cov tuam txhab tsim tsheb yuav tsum tau teeb tsa lub teeb ua haujlwm nruab hnub rau txhua lub tsheb tshiab. Nco ntsoov tias cov nqaj qis yog siv rau kev tsav tsheb thaum hmo ntuj, nag lossis huab cua.
