qhov twg zoo dua thiab vim li cas? Tsuas yog xyaum xwb!
Automotive technology yog evolving ntawm ib tug ceev ceev. Yog tias ob peb xyoos dhau los, cov tsheb zoo tshaj plaws tau nruab nrog LED hloov lub taub hau, hnub no txawm tias lub tsheb nruab nrab cov peev nyiaj tau nruab nrog diodes. Cov lus nug tshwm sim tshwm sim: LED optics puas zoo li xenon thiab halogen tuaj yeem tso tseg rau nws qhov laj thawj? Cia peb sim daws qhov teeb meem no ntawm peb lub vev xaib Vodi.su.
Xenon: ntaus ntawv thiab lub hauv paus ntsiab lus ntawm kev ua haujlwm
Yav dhau los, peb twb tau txiav txim siab nyob rau hauv kev nthuav dav cov cuab yeej ntawm xenon thiab bi-xenon optics. Cia peb nco qab cov ntsiab lus tseem ceeb.
xenon yog dab tsi?
- ib lub khob ntim nrog cov roj inert;
- muaj ob lub electrodes nyob rau hauv lub hwj, ntawm uas ib tug hluav taws xob arc tshwm sim;
- ignition thaiv.
Lub ignition unit yog xav tau los tsim hluav taws xob nrog ib tug voltage ntawm 25 txhiab volts los tsim ib tug arc. Qhov kub ntawm xenon yog li ntawm 4000-6000 Kelvin thiab lub teeb yuav muaj xim daj lossis xiav. Txhawm rau kom tsis txhob dig muag cov tsav tsheb, tsuas yog xenon nrog kev kho lub taub hau tsis siv neeg raug tso cai siv. Thiab kev hloov ntawm qhov siab thiab qis qis tshwm sim ua tsaug rau lub tshuab hluav taws xob thiab lub lens tshwj xeeb. Lub teeb taub hau kuj tau nruab nrog lub teeb taub hau los yog ntxhua khaub ncaws, vim tias txhua qhov av ua rau lub teeb pom kev ntawm lub teeb thiab nws pib qhov muag tsis pom kev.
Nco qab tias tsuas yog kev teeb tsa ntawm cov ntawv pov thawj "kev cai lij choj" xenon tau tso cai, uas yog qhov tsim nyog rau koj lub tsheb. Raws li qhov thib peb ntawm Tshooj 12.5 ntawm Txoj Cai Tswjfwm Kev Ua Phem, kev tsav tsheb nrog xenon tsis tau lees paub yuav ua rau muaj kev cuam tshuam ntawm txoj cai rau lub sijhawm rau lub hlis mus rau ib xyoos. Raws li, rau nws cov installation, koj yuav tsum tau txais kev tso cai los ntawm qhov chaw nres tsheb.
LED teeb
LEDs yog ib tug txawv kiag li technology. Glow tshwm sim thaum muaj hluav taws xob tam sim no dhau los ntawm tus neeg xyuas pib.
Ntaus:
- Lub teeb-emitting diode (LED) - lub teeb LED nws tus kheej;
- tsav tsheb - fais fab mov, ua tsaug rau qhov koj tuaj yeem ruaj khov cov khoom siv tam sim no thiab tswj qhov kub ntawm qhov ci;
- lub tshuab ua kom txias txias rau lub caij LED, vim nws tau kub heev;
- lim kom nce lossis txo lub teeb kub.
LED headlights tsuas yog ntsia rau ntawm lub tsheb nrog adaptive optics. Piv txwv li, multifunctional LED headlights yog siv niaj hnub no, uas tau hloov mus rau huab cua thiab ceev ntawm kev txav. Xws li ib qho kev txheeb xyuas cov ntaub ntawv los ntawm cov nag sensors, ceev, lub kauj lub kaum sab xis. Lawm, xws li Library tsis pheej yig.
Xenon vs LEDs
Cia peb tham txog qhov zoo thiab qhov tsis zoo ua ntej.
Qhov zoo ntawm xenon:
- ci ntsa iab yog qhov tseem ceeb ntxiv, cov teeb no muab kev pom zoo txawm tias huab cua los nag;
- Lub neej ua haujlwm ntev, kwv yees li ntawm 2500-3000 teev, uas yog, qhov nruab nrab ntawm 3-4 xyoo ua ntej hloov lub teeb;
- kev ua haujlwm siab zoo hauv cheeb tsam ntawm 90-94%, feem, xenon tsis kub ntau npaum li cov pa halogens;
- qhov muag teev yuav tsum tau hloov.
Muaj, ntawm chav kawm, downsides. Ua ntej, cov no yog cov teeb meem kev teeb tsa, txij li cov khoom siv hluav taws xob feem ntau tsis haum rau cov qauv optics thiab muab tso rau hauv qab lub hood. Ib chav ignition cais yuav tsum tau muaj rau txhua qhov chaw kho qhov muag. Qhov thib ob, xenon siv hluav taws xob ntau dua li LEDs lossis halogens, thiab qhov no yog qhov ntxiv ntawm lub tshuab hluav taws xob. Thib peb, cov kev cai nruj heev tau muab tso rau pem hauv ntej rau kev kho qhov siab thiab qis nqaj thiab rau qhov xwm txheej ntawm optics nws tus kheej - yuav tsum tsis txhob muaj qhov tawg ntawm lub teeb taws. Yog hais tias ib qho ntawm cov qij tau hlawv tawm, ob qho tib si yuav tsum tau hloov.
Qhov zoo ntawm LED teeb pom kev zoo:
- kev siv hluav taws xob qis;
- yooj yim installation;
- tsis muaj kev tso cai yuav tsum tau - tsis muaj kev lav phib xaub rau kev siv LEDs;
- tsis txhob dig muag cov neeg tsav tsheb thiab cov neeg taug kev;
- Nyob rau hauv cov nqe lus ntawm brightness, lawv mus txog xenon, thiab ib co ntawm cov kev hloov kho tshiab txawm tshaj nws.
Txawm li cas los xij, ib tus yuav tsum tsis txhob hnov qab txog qhov tsis txaus ntseeg tseem ceeb. Ua ntej ntawm tag nrho cov, tsis zoo li xenon thiab bi-xenon, LEDs tsis tsim ib qho kev taw qhia ntawm lub teeb. Txawm hais tias lawv yuav luag sib npaug ntawm qhov ci, xenon muab kev pom zoo dua nyob rau hauv tib lub sijhawm. Yog li, yog tias koj muaj bi-xenon, tom qab ntawd nrog txoj kab siab siab, tus neeg taug kev ntawm txoj kev tuaj yeem pom ntawm qhov deb ntawm 100-110 meters. Thiab nrog LEDs, qhov kev ncua deb no txo mus rau 55-70 meters.
Qhov thib ob, LED tsav tsheb tau kub heev, uas txo qis lawv lub neej kev pab cuam. Hauv qhov no, xenon muaj txiaj ntsig ntau dua, vim nws yuav tsum tau hloov tsawg dua. Qhov thib peb, txawm hais tias LED teeb siv hluav taws xob tsawg, lawv muaj kev nkag siab zoo rau lub zog hluav taws xob hauv lub tsheb network.
Txawm li cas los xij, hauv kev pom zoo ntawm LEDs, yog qhov tseeb tias qhov kev siv tshuab no tau tsim sai heev. Yog li, kaum xyoo dhau los, tsuas yog ob peb paub txog LED teeb pom kev zoo, tab sis hnub no nws tau siv yuav luag txhua qhov chaw. Yog li, nws muaj kev ruaj ntseg hais tias nyob rau hauv ob peb xyoos, LED headlights yuav dhau tag nrho lawv cov predecessors nyob rau hauv cov nqe lus ntawm lawv cov yam ntxwv.
