Lub taub hau teeb
Automotive headlights feem ntau yog tsim los ntawm peb qhov chaw: lub teeb pom kev zoo, reflector thiab daim iav sib xws (astigmatism mirror).
ib bulb
Cov qhov muag teev uas siv nyob rau hauv lub tsheb headlights yog incandescent qhov muag teev, halogen tungsten qhov muag teev, tshiab high-brightness arc teeb thiab hais txog.
(1) Incandescent noob: nws filament yog ua los ntawm tungsten hlau (tungsten muaj lub siab melting point thiab lub teeb muaj zog). Thaum lub sijhawm tsim khoom, txhawm rau txhawm rau ua kom lub neej ua haujlwm ntawm lub teeb, lub noob tau ntim nrog cov roj inert (nitrogen thiab nws qhov sib xyaw ntawm cov roj inert). Qhov no tuaj yeem txo cov evaporation ntawm tungsten hlau, nce qhov kub thiab txias ntawm filament, thiab txhim khu lub luminous efficiency. Lub teeb los ntawm lub teeb incandescent muaj yellowish tinge.
(2) Tungsten halide teeb: tungsten halide lub teeb yog muab tso rau hauv cov roj inert rau hauv ib qho halide caij (xws li iodine, chlorine, fluorine, bromine, thiab lwm yam), siv lub hauv paus ntsiab lus ntawm tungsten halide recycling cov tshuaj tiv thaiv, uas yog, gaseous tungsten evaporating los ntawm filament reacts nrog halogen los tsim ib tug volatile tungsten halide, uas diffuses mus rau qhov kub ntawm qhov chaw nyob ze ntawm lub filament, thiab decomposed los ntawm tshav kub, yog li ntawd lub tungsten rov qab mus rau lub filament. Cov halogen tso tawm txuas ntxiv mus txuas ntxiv thiab koom nrog cov tshuaj tiv thaiv lub voj voog tom ntej, yog li lub voj voog txuas ntxiv, yog li tiv thaiv cov evaporation ntawm tungsten thiab blackening ntawm lub teeb. Tungsten halogen lub teeb me me yog me me, lub teeb lub plhaub yog ua los ntawm quartz iav nrog kub tsis kam thiab siab mechanical zog, nyob rau hauv tib lub hwj chim, lub brightness ntawm tungsten halogen teeb yog 1.5 npaug ntawm lub teeb incandescent, thiab lub neej yog 2 mus rau 3x ntev.
(3) Tshiab high-brightness arc teeb: Lub teeb no tsis muaj ib txwm filament nyob rau hauv lub teeb. Hloov chaw, ob lub electrodes tau muab tso rau hauv ib lub raj quartz. Lub raj yog ntim nrog xenon thiab kab hlau (los yog hlau halides), thiab thaum muaj txaus arc voltage ntawm lub electrode (5000 ~ 12000V), cov roj pib ionize thiab ua hluav taws xob. Cov roj atoms nyob rau hauv lub xeev zoo siab thiab pib emit lub teeb vim lub zog theem ntawm cov electrons. Tom qab 0.1s, me me ntawm mercury vapor yog evaporated nruab nrab ntawm cov electrodes, thiab lub hwj huam mov yog tam sim ntawd hloov mus rau mercury vapor arc tawm, thiab ces pauv mus rau lub halide arc teeb tom qab kub nce. Tom qab lub teeb ncav cuag qhov kub thiab txias ua haujlwm ntawm lub teeb, lub zog ntawm kev tswj cov arc tawm yog tsawg heev (txog 35w), yog li 40% ntawm lub zog hluav taws xob tuaj yeem txuag tau.
2. reflector
Lub luag hauj lwm ntawm lub reflector yog ua kom lub polymerization ntawm lub teeb emitted los ntawm lub teeb mus rau hauv ib tug muaj zog beam kom nce lub irradiation nrug.
Cov duab saum npoo ntawm daim iav yog qhov sib hloov paraboloid, feem ntau yog ua los ntawm 0.6 ~ 0.8mm nyias steel ntawv stamping lossis ua los ntawm iav, yas. Sab hauv yog plated nrog nyiaj, aluminium lossis chrome thiab tom qab ntawd polished; Lub filament yog nyob rau ntawm lub focal point ntawm daim iav, thiab feem ntau ntawm nws lub teeb rays yog reflected thiab tua tawm mus rau hauv qhov kev ncua deb li parallel beams. Lub teeb tsis muaj daim iav tuaj yeem pom qhov deb li ntawm 6m, thiab lub teeb sib luag uas pom los ntawm daim iav tuaj yeem pom qhov deb ntawm ntau tshaj 100m. Tom qab daim iav, muaj ib qho me me ntawm lub teeb tawg, uas qhov nce siab yog qhov tsis muaj txiaj ntsig, thiab lub teeb sab nraud thiab sab qis yuav pab kom pom kev ntawm txoj kev ntog thiab kev thaiv ntawm 5 mus rau 10m.
3. Lens
Pantoscope, tseem hu ua astigmatic iav, yog ib qho kev sib xyaw ntawm ob peb qhov tshwj xeeb prisms thiab lo ntsiab muag, thiab cov duab feem ntau yog ncig thiab duab plaub. Lub luag haujlwm ntawm daim iav sib txuam yog txhawm rau txhawm rau qhov sib npaug ntawm lub teeb pom kev los ntawm daim iav, kom txoj kev nyob rau hauv pem hauv ntej ntawm lub tsheb muaj lub teeb pom kev zoo thiab zoo ib yam.
Yuav ua li cas nrog dej pos huab nyob rau hauv lub tsheb headlights?
Lub tsheb taub hau muaj dej pos tuaj yeem kho tau hauv txoj kev no: qhib lub teeb taub hau kom evaporate ib txwm, raug rau lub hnub, tshem tawm cov phom dej siab, hloov lub taub hau teeb ntxoov ntxoo, tshuab nrog lub tshuab ziab plaub hau, hloov lub taub hau foob, tso tawm dehumidifier , ntxiv cov kiv cua txias, hloov lub taub hau.
Qhov ua rau qhov tsis ua haujlwm ntawm lub teeb taub hau?
Cov laj thawj vim li cas lub teeb taub hau tsis ua haujlwm yuav suav nrog:
Lub teeb puas : lub teeb yog ib qho hnav, siv sij hawm ntev los yog txoj kev tsis zoo yuav ua rau muaj kev puas tsuaj. cov
overheat los yog luv luv Circuit Court: overheat los yog luv luv Circuit Court ntawm cov hlau yuav cuam tshuam rau tam sim no kis tau tus mob thiab ua rau lub taub hau teeb tsis tig. cov
Relay lossis kev sib txuas ua ke tsis ua haujlwm : Relay lossis kev sib txuas ua ke tsis ua haujlwm tuaj yeem ua rau lub taub hau tsis pom. cov
Tshuab fuse: tshuab fuse yog ib qho ua rau, xyuas thiab hloov lub fuse tuaj yeem daws qhov teeb meem. cov
kab qhib, luv luv los yog tawg: tsis zoo los yog xoob kab kev twb kev txuas, kev sib koom ua ke tsis nyob rau hauv qhov chaw kuj yuav ua rau lub taub hau tsis nyob rau.
Voltage regulator tsis ua hauj lwm : Lub voltage regulator tsis ua hauj lwm tuaj yeem ua rau qhov voltage siab dhau, uas tuaj yeem ua rau lub teeb hlawv. cov
Lub roj teeb qis: Lub roj teeb qis yuav cuam tshuam rau kev ua haujlwm ntawm lub teeb taub hau. cov
xoob headlamp plug : tsis tu ncua xyuas lub headlamp plug yog ruaj, raws sij hawm zawm yuav zam tau tej teeb meem. cov
Txhawm rau daws cov teeb meem no, cov kev ntsuas hauv qab no tuaj yeem ua:
Tshawb xyuas lub teeb kom puas thiab hloov nws nrog ib qho tshiab yog tias tsim nyog.
Xyuas cov xov hlau rau overheating lossis luv circuits, thiab kho lossis hloov lawv yog tias tsim nyog.
Xyuas kom cov relays thiab cov keyboards sib txuas ua haujlwm tau zoo, thiab kho lossis hloov lawv yog tias tsim nyog.
Xyuas seb lub fuse puas tau tshuab thiab hloov lub fuse yog tias tsim nyog.
Xyuas cov kab kom qhib, luv luv lossis tawg, thiab kho yog tias tsim nyog.
Txheeb xyuas tias qhov ntsuas hluav taws xob ua haujlwm tau zoo thiab kho lossis hloov yog tias tsim nyog.
Xyuas seb lub roj teeb puas tau them tag nrho, thiab them lossis hloov lub roj teeb yog tias tsim nyog.
Xyuas kom lub headlamp plug yog ruaj thiab nruj yog tias tsim nyog.
Los ntawm cov kauj ruam no, koj tuaj yeem kuaj xyuas tau zoo thiab daws qhov teeb meem ntawm lub teeb lub tsheb tsis nyob. cov
