It yog paub zoo tias lub teeb lub tsheb tuaj nyob rau hauv ob lub ntsiab: lub teeb qis (tseem hu ua dipped beam lossis "ze lights") thiab high beam (tseem hu ua main beam lossis "fab teeb"). Lub teeb taub hau qis yog cov teeb pom kev zoo tshaj plaws hauv peb lub hnub tsav tsheb vim tias lawv tau tsim raws li cov qauv kev cai. Lawv muaj cov qauv kab rov tav qis dua, uas tiv thaiv lawv los ntawm kev cuam tshuam rau kev nyab xeeb ntawm cov neeg tsav tsheb, cia peb siv lawv li niaj zaus.
Yog li vim li cas coob tus neeg tseem siv cov teeb pom kev siab siab? Sib nrug los ntawm ob peb tus neeg uas coj tus cwj pwm tsis zoo, ntau tus neeg raug yuam ua li ntawd vim lub teeb taws teeb ntawm lawv lub tsheb. Ntau tus qauv tsheb nkag tau tseem siv lub teeb taws halogen, uas muaj qhov ci ntsa iab tsis zoo thiab kev ua haujlwm tsis zoo, ua rau nws nyuaj rau pom txoj kev ua ntej kom meej meej thaum siv cov teeb pom kev qis.
Nyob rau hauv tas li ntawd, cov neeg feem ntau subconsciously hloov mus rau high beams vim hais tias lawv muaj ib tug dav illumination ntau yam. Txawm li cas los xij, qhov no cuam tshuam rau kev nyab xeeb ntawm cov neeg tsav tsheb yuav los, thiab peb txhua tus tau dhau los ua neeg raug tsim txom hauv qhov xwm txheej no.
Halogen headlights, uas feem ntau pom nyob rau hauv lub tsheb, muaj ib tug kuj yooj yim tsim qauv uas muaj xws li lub tais-zoo li tus reflector thiab lub teeb halogen. Lawv qhov ci ntsa iab heev, thiab yog tias koj tseem siv lub teeb taws halogen, koj tuaj yeem pom koj tus kheej squinting saib txoj kev tom ntej.
Yog li, yuav ua li cas yog tias halogen headlights tsis ci txaus? Qee tus neeg xaiv hloov kho rau LED teeb taub hau (raws li qhia hauv daim duab). LED headlights muaj qhov ci siab dua piv rau halogen headlights. Txawm li cas los xij, cov teeb ci LED no muaj qhov ua tau zoo nruab nrab piv rau kev ua haujlwm siab ua ke LED dual-lens taub hau teeb. Lawv zoo li tsis muaj zog hauv kev sib piv.
Ua ntej, cov teeb ci LED no muaj kev teeb tsa qis dua thiab siv cov chips LED tsis muaj zog. Tsis tas li ntawd, tus naj npawb ntawm LED chips siv kuj qis dua piv rau kev sib xyaw LED dual-lens taub hau teeb. Qhov thib ob, tsis muaj kev txhawb nqa ntawm lo ntsiab muag, lub teeb los ntawm cov teeb ci LED no tshwm sim tawg thiab tsis pom, ua rau lub teeb ci dimmer.
Nyob rau hauv cov nqe lus ntawm illumination kev ua tau zoo, LED headlights yuav tshwm whiter piv rau halogen headlights. Lub teeb dawb muab kev nkag siab ntawm qhov ci. Txawm li cas los xij, qhov tseeb ntawm qhov ci ci yog txwv, thiab sib nrug los ntawm qhov chaw ci ntsa iab, qhov seem ntawm lub teeb faib yog zoo li halogen headlights.
Thaum kawg, cia peb tham txog qhov kev hloov pauv kev ua si uas kuv tau hais thaum pib: kev sib xyaw LED dual-lens taub hau. Nws yeej sawv tawm yam tsis muaj kev sib piv. LED dual-lens headlights muab cov teeb pom kev zoo zoo. Lawv tsis tsuas yog txhim kho qhov ci ntsa iab xwb tab sis kuj muaj thaj chaw dav dav. Koj tuaj yeem pom meej ntawm ob sab, thiab txawm tias cov phab ntsa nyob deb tau teeb pom kev nrog qhov pom tseeb tshwj xeeb!
