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.
The surface shape of the mirror is a rotating paraboloid, generally made of 0.6 ~ 0.8mm thin steel sheet stamping or made of glass, plastic. Sab hauv nto yog plated nrog nyiaj, txhuas lossis chrome thiab ces polished; The filament is located at the focal point of the mirror, and most of its light rays are reflected and shot out into the distance as parallel beams. The light bulb without a mirror can only illuminate a distance of about 6m, and the parallel beam reflected by the mirror can illuminate a distance of more than 100m. After the mirror, there is a small amount of scattered light, of which the upward is completely useless, and the lateral and lower light helps to illuminate the road surface and curb of 5 to 10m.
sib faib
Lub headlamp optical system yog kev sib xyaw ua ke ntawm lub teeb ci, muaj cov duab pom zoo thiab sib phim. According to the different structure of the headlamp optical system, the headlamp can be divided into three kinds: semi-closed, closed and projective.
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.
(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.
