Lub taub hau teeb.
Automotive headights feem ntau muaj ntawm peb ntu: teeb tsa teeb, tsom kwm thiab phim daim iav (astigmatism daim iav).
1. Noob
Cov qhov muag teev siv nyob rau hauv lub taub hau tsheb yog incandescent qij, halogen tungsten qhov muag teev, lub teeb ci tshiab arc teeb thiab lwm yam.
(1) Incandescent bemb: nws cov ntsiab lus yog ua los ntawm tungsten hlau (tungsten muaj lub siab melting taw tes thiab muaj zog teeb). Thaum tsim khoom, nyob rau hauv thiaj li yuav nce kev pabcuam lub neej, muaj cov noob tau sau nrog cov roj inert (nitrogen thiab nws sib xyaw ntawm cov roj inert). Qhov no tuaj yeem txo cov evaporation ntawm tungsten hlau, nce qhov kub ntawm cov ntsiab lus, thiab txhim kho lub luminous efficiency. Lub teeb ci los ntawm lub teeb daj incandescent muaj lub tinge daj.
(2) tungsten halide teeb Mus rau qhov chaw kub nyob ze rau Falament kub, thiab yog decomposed los ntawm tshav kub, yog li ntawd lub tungsten tau rov qab los rau filament. Qhov tso tawm halogen tseem diffuse thiab koom nrog hauv cov kev sib tw tom ntej, yog li kev sib tw txuas ntxiv, yog li tiv thaiv kev tshaj lij ntawm lub teeb ntawm cov noob. Tungsten Halogen lub teeb lub teeb loj yog me me, lub qhov muag plhaub ua tau zoo thiab lub sijhawm muaj zog, thiab lub neej muaj 2 txog 3 npaug.
(3) Kev pib lub siab tshiab ntawm Arc Teeb: Lub teeb no tsis muaj ib txwm muaj teeb meem nyob rau hauv lub teeb. Hloov chaw, ob lub electrodes tau muab tso rau hauv lub raj quartz. Lub raj ntim nrog Xenon thiab Trace hlau (lossis cov hlau ua haujlwm), thiab thaum muaj cov roj ntsha hluav taws xob hauv electrode (5000 ~ 12000v), roj av pib ionize thiab ua hluav taws xob. Cov pa roj atoms yog nyob rau hauv lub xeev zoo siab thiab pib emit teeb vim kev hloov pauv ntawm cov tshuab hluav taws xob. Tom qab 0.1s, ib qho me me ntawm mercury vapor yog evaporated ntawm cov elecury arc paug, thiab tom qab ntawd hloov mus rau lub teeb halcurred arc tawm, thiab tom qab ntawd hloov mus rau lub teeb halcurred arc tshem tawm, thiab tom qab ntawd hloov mus rau lub teeb halcurred arc tshem tawm, thiab tom qab ntawd hloov mus rau hauv Halide Arc teeb tom qab kub nce. Tom qab lub teeb mus txog qhov ua hauj lwm ib txwm ua haujlwm ntawm lub teeb, lub zog ntawm kev tswj cov kev paug ARC yog tsawg heev (li 40% ntawm hluav taws xob tau txais kev cawmdim.
2. Reveyoror
Lub luag haujlwm ntawm lub reflector yog kom ua kom tiav rau lub teeb ci ntsa iab los ntawm lub teeb rau hauv cov nqaj muaj zog kom nce qhov tsis sib haum.
Cov duab saum npoo ntawm daim iav yog cov kev sib hloov paraboloid, feem ntau ua los ntawm 0.6 ~ 0.8mm cov ntawv hlau nyias nyias stamping lossis ua los ntawm iav, yas. Sab hauv nto yog plated nrog nyiaj, txhuas lossis chrome thiab ces polished; Cov ntsiab lus yog nyob ntawm lub focal point ntawm daim iav, thiab feem ntau ntawm nws cov teeb ci yog xav txog thiab tua mus rau qhov deb li thaum tig mus rau kev sib tw. Lub teeb lub teeb tsis muaj daim iav muaj peev xwm ua kom pom kev deb ntawm txog li 6m, thiab Parallel Nqe tau cuam tshuam los ntawm daim iav tuaj yeem ua kom pom kev deb ntawm ntau dua 100m. Tom qab daim iav, muaj me me ntawm tawg, ntawm qhov upward yog kiag li tsis zoo, thiab qis dua lub teeb pab ua kom pom txoj kev saum npoo thiab teeb ntawm 5 txog 10m.
3. Lens
Pantoscope, tseem hu ua astigmatic iav, yog kev sib xyaw ua ke ntawm ntau qhov kev tshwj xeeb thiab lo ntsiab muag tshwj xeeb, thiab cov duab feem ntau ncig thiab duab plaub. Lub luag haujlwm ntawm daim iav sib luag yog txhawm rau ua kom lub ntsej muag pom kev tiag tiag
sib faib
Lub headlamp optical system yog kev sib xyaw ua ke ntawm lub teeb ci, muaj cov duab pom zoo thiab sib phim. Raws li cov qauv sib txawv ntawm cov headlamp optical system, cov headlamp tuaj yeem faib ua peb yam: kaw, kaw thiab projective.
1. Semi-nyob rau hauv taub hau
Semi-kaw Headlamp teeb pom kev zoo nkauj thiab daim iav lo ua ke tsis tuaj yeem muab tshem tawm ntawm lub teeb, ib nrab kaw lub teeb, tsuas yog qhov tsis zoo yog kev sib khi tsis zoo. Lub taub hau sib xyaw ua ke ntawm cov teeb liab tig xub ntiag, lub teeb ci ntsa iab thiab lub teeb ci ntsa iab rau tag nrho cov khoom siv orge, thiab lub teeb ci tau yooj yim los ntawm sab nraum qab. Nrog ua ke taws teeb, automotive manufacturers tuaj yeem tsim ib qho teeb meem sib piv ntawm kev thov kom muaj kev lag luam tsheb aerodynamic, roj kev lag luam thiab cov tsheb styroning.
2. Hauv taub hau
Ntawm cov thawj ntxwv ntawm cov thawj ntxwv tseem muab faib ua cov qauv ntawm cov headlaspas thiab halogen nrog headlamps.
Lub cev kho qhov muag ntawm tus qauv ua ke headlamp yog rau fuse thiab Weld lub ntsej muag sib dhos thiab cov ntawv sib piv rau tag nrho los ua kom muaj cov teeb tsa vaj tse, thiab cov ntsiab lus rau lub hauv paus cuam tshuam. Lub reflector nto yog aluminized los ntawm lub tshuab nqus tsev, thiab lub teeb muaj nrog cov roj hauv plab thiab halogen. Qhov zoo ntawm cov qauv no muaj kev sib khi zoo, daim iav yuav tsis muaj kuab paug los ntawm cov huab cua, lub neej kev pabcuam siab thiab ntev. Txawm li cas los xij, tom qab cov ntsiab lus tau hlawv tawm, tag nrho cov teeb tsa pab pawg xav tau hloov, thiab tus nqi siab dua.
3. Projective Headlamp
Lub qhov muag kho qhov muag ntawm txoj hauj lwm headlamp feem ntau yog tsim ntawm lub teeb tsa lub teeb, Reving, daim iav sib phim thiab conveex txuam daim iav. Siv cov ntawv tsom iav tuab heev tsis-engraved convex daim iav, daim iav yog oval. Yog li nws sab sab nraud ntawm lub cheeb yog me heev. Lub teeb taws teeb lub taub hau muaj ob lub ntsiab lus, thawj lub tsom xam yog lub teeb thiab lub hom phiaj thib ob yog tsim nyob rau hauv lub teeb. Tsom lub teeb los ntawm daim iav convex thiab nrum nws mus rau qhov deb. Nws zoo dua yog tias kev ua kom pom tseeb yog qhov zoo, thiab nws txoj kev teeb tsa Ray yog:
(1) Lub teeb emitted rau sab qaum kev hla dhau ntawm lub teeb pom kev hla dhau ntawm qhov kev tsom xam thib ob, thiab yog tsom mus rau qhov kev ncua deb los ntawm kev sib tw convex.
(2) Nyob rau tib lub sijhawm, lub teeb emitted rau qis dua ntawm cov teeb pom kev sib tw thiab tom qab ntawd pov rau qhov kev ua kom pom tseeb, thiab tsom mus rau qhov kev ncua deb los ntawm kev sib tw convex phim daim iav.
Hauv kev siv cov tsheb, qhov yuav tsum tau ua rau cov teeb pom kev zoo yog: tab sis kuj yuav tsum tau txhob dig muag tus neeg tsav tsheb yuav tsum them sai sai rau cov ntsiab lus hauv qab no:
(1) Khaws cov headlamp pantoscope huv si, tshwj xeeb tshaj yog thaum tsav tsheb hauv nag thiab daus, av thiab av yuav txo cov teeb pom kev zoo ntawm lub taub hau los ntawm 50%. Qee cov qauv yog nruab nrog taws teeb dej thiab dej txau dej.
(2) Thaum ob lub tsheb sib ntsib thaum hmo ntuj, ob lub tsheb yuav tsum tua lub siab loj ntawm cov headlamp thiab hloov mus rau lub teeb ze rau kev nyab xeeb tsav tsheb.
(3) Txhawm rau kom muaj kev ua haujlwm kom ntseeg tau tias qhov kev ua haujlwm ntawm headlamp, lub headlamp nqaj yuav tsum tau kuaj thiab hloov kho tom qab lub tsheb yog tsav 10,000 km.
(4) Txheeb xyuas lub teeb ntawm lub teeb thiab cov hlau hauv paus rau oxidation thiab loosening, kom ntseeg tau tias lub txuas sib tiv tauj kev ua tau zoo thiab cov hlau hauv paus yog txhim khu kev qha. Yog tias qhov kev sib tiv thaiv yog xoob, thaum lub taub hau tau hloov mus, nws yuav ua rau muaj kev poob siab tam sim no, thiab yog tias kev sib cuag ntawm lub teeb, nws yuav txo cov ci ci ntawm lub teeb vim qhov nce ntawm qhov kev tiv thaiv siab poob.
