Nyob rau hauv niaj hnub automotive teeb pom kev zoo technology, halogen teeb, HID (high-intensity gas discharge lamps) thiab LED (light-emitting diode) teeb yog peb hom tshaj plaws. Txhua lub teeb muaj nws tus kheej zoo thiab qhov tsis zoo, tab sis nyob rau hauv tib lub hwj chim tej yam kev mob, lub tshav kub tsim los ntawm cov teeb sib txawv muaj qhov sib txawv loj.
Halogen teeb
Halogen teeb yog hom tsoos automotive headlights. Nws txoj haujlwm ua haujlwm zoo ib yam li cov teeb pom kev zoo tib yam, thiab cov tungsten filament yog rhuab los ntawm hluav taws xob tam sim no kom nws ci. Lub plhaub iav ntawm lub teeb halogen yog ntim nrog cov roj halogen (xws li iodine lossis bromine), uas tuaj yeem txuas lub neej ntawm cov filament thiab nce qhov ci.
Tsis tas li ntawd, halogen teeb ua kom muaj cua sov ntau, siv ntau lub zog, thiab qhov kub tuaj yeem ncav cuag ntau dua 200 degrees Celsius thaum ua haujlwm.
HID teeb, tseem hu ua high-intensity gas discharge lamps, emit light by filling the bulb with inert gases such as xenon and generating arc under high voltage.
Qhov kub ntawm HID teeb tuaj yeem ncav cuag 300-400 degrees Celsius thaum ua haujlwm ntau tshaj kaum feeb tom qab tig, thaum qhov kub ntawm sab nraum lub teeb yog me ntsis qis dua qhov kub ntawm cov tub ntxhais, thiab cov cua txias feem ntau yog siv.
LED teeb yog ib hom tsheb taub hau uas tau nrov zuj zus nyob rau xyoo tas los no. Nws emits lub teeb los ntawm lub teeb-emitting diodes nyob rau hauv qhov kev txiav txim ntawm tam sim no, thiab muaj cov yam ntxwv ntawm high efficiency thiab lub zog txuag.
Lub tshav kub tsim los ntawm LED teeb yog qhov qis, feem ntau nyob ib ncig ntawm 80 degrees Celsius. Qhov no yog vim qhov kev hloov pauv ntawm electro-optical efficiency ntawm LED teeb yog siab, thiab feem ntau ntawm lub zog yog hloov mus rau lub teeb lub zog es tsis yog lub zog hluav taws xob.
Vim li cas LEDtaub hauteeb ua kom muaj cua sov tsawg dua?
Electro-optical conversion
Lub electro-optical conversion efficiency ntawm LED teeb yog siab heev, thiab feem ntau ntawm cov hluav taws xob lub zog yuav hloov mus rau hauv lub teeb lub zog. Hauv qhov sib piv, halogen teeb thiab HID teeb ua kom muaj cua sov ntau thaum lub teeb-emitting txheej txheem.
Kev siv hluav taws xob tsawg
LED teeb muaj kev siv hluav taws xob tsawg, feem ntau yog li ntawm ob peb watts mus rau kaum tawm watts, thaum lub teeb halogen thiab HID teeb muaj ntau dua lub zog siv.
Cov khoom siv semiconductor
LED teeb siv cov ntaub ntawv semiconductor los tawm lub teeb, uas tsis ua kom muaj cua sov ntau zoo li tungsten filaments thaum tam sim no dhau los ntawm lawv. Lub teeb-emitting txheej txheem ntawm cov ntaub ntawv semiconductor yog ntau npaum thiab ruaj khov.
Thaum tshav kub kub dissipation tsim
Txawm hais tias LED teeb lawv tus kheej tsim hluav taws xob tsawg, lawv muaj kev nkag siab rau qhov kub thiab txias, yog li LED teeb xav tau kev ua haujlwm ntxiv los pab kom tag nrho lub teeb taub hau ua kom sov.
Muaj ntau txoj hauv kevdissipate tshav kub rau LED headlights. Qhov nrov tshaj plaws cua kub dissipation txoj kev yog radiator + kiv cua.
LED lub taub hau nrog kev ua kom sov zoo
Qhov noK11 LED taub hau teebyog ua los ntawm aviation aluminium, uas muaj kev ua haujlwm zoo heev thiab cua sov dissipation. Sab hauv ntawm lub teeb taub hau siv superconducting thermal copper khoom thiab cov kiv cua txias tsim, uas tsis yog tsuas yog siab nyob rau hauv brightness, tab sis kuj muaj zoo tshav kub dissipation thiab kev pab cuam lub neej.
Lub teeb taub hau no tuaj yeem tiv taus qhov kub thiab txias ib puag ncig, thiab muaj lub kiv cua tsis muaj dej, uas tuaj yeem muab cov teeb pom kev zoo rau koj txawm tias nyob rau hauv ib puag ncig hnyav.
