Cov tsheb niaj hnub no tau nruab nrog cov khoom siv teeb pom kev zoo nruab rau hauv pem hauv ntej thiab nram qab.Kev tsim ntawm lub teeb ci thiab nws cov xim nyob rau hauv lub teeb yog muab los ntawm diffusers - nyeem tag nrho cov no, lawv hom, tsim, xaiv thiab hloov kho kom raug hauv kab lus no.
Dab tsi yog lub teeb diffuser
Lub teeb pom kev hauv qab yog ib qho khoom siv kho qhov muag ntawm cov khoom siv teeb pom kev hauv qab ntawm lub tsheb, rov faib (sib faib) thiab / lossis xim lub teeb flux los ntawm lub teeb, thiab xyuas kom meej tias cov yam ntxwv ntawm lub teeb tom qab ua tau raws li cov kev cai ntawm cov qauv.
Txhua lub tsheb, raws li cov qauv hauv kev quab yuam, yuav tsum tau nruab nrog cov khoom siv hluav taws xob sab nraud rau ntau lub hom phiaj, nyob rau pem hauv ntej thiab nram qab.Nyob rau tom qab ntawm lub tsheb, tsheb npav, tsheb laij teb, tsheb laij teb thiab lwm yam khoom siv muaj cov khoom siv teeb pom kev zoo uas ua kom muaj kev nyab xeeb: cov taw qhia, lub teeb nres, lub teeb nres tsheb, lub teeb nres tsheb thiab lub teeb liab rov qab.Cov khoom siv no yog tsim los ntawm cov teeb pom kev sib cais lossis pawg, cov yam ntxwv tsim nyog uas tau muab los ntawm cov pob tshab - diffusers.
Lub teeb nraub qaum diffuser ua ntau yam haujlwm:
● Kev faib tawm ntawm cov luminous flux los ntawm lub teeb - lub teeb los ntawm qhov chaw taw tes (lub teeb) ua kom sib npaug ntawm ib qho chaw, uas muab kev pom zoo ntawm hluav taws los ntawm ntau lub kaum ntse ntse;
● Painting lub luminous flux nyob rau hauv cov xim tswj rau txhua lub teeb;
● Kev tiv thaiv cov teeb thiab lwm yam sab hauv ntawm lub teeb los ntawm qhov tsis zoo ib puag ncig thiab kev cuam tshuam rau cov neeg kho tshuab.
Yog tias lub diffuser puas lawm, cov ntaub ntawv cov ntsiab lus thiab kev ua haujlwm ntawm lub teeb nyem yuav raug cuam tshuam, yog li qhov no yuav tsum tau hloov lub sijhawm luv luv.Thiab txhawm rau ua qhov kev xaiv zoo, nws yog ib qho tsim nyog yuav tsum nkag siab txog hom uas twb muaj lawm, tsim thiab nta ntawm diffusers.
Tsim thiab hom teeb pom kev zoo tom qab lo ntsiab muag
Structurely, txhua qhov diffuser ntawm lub teeb nraub qaum yog lub hau npog ua los ntawm cov pob tshab thiab cov xim pleev xim rau hauv lub teeb, uas yog ntsia rau ntawm lub teeb nrog cov ntsia hlau thiab los ntawm lub sealing gasket, npog lub teeb thiab lwm qhov chaw.Cov diffusers feem ntau yog ua los ntawm cov tsis tu ncua lossis fiberglass-reinforced polycarbonate, pob tshab thiab xim loj.
Nyob rau sab hauv ntawm lub lo ntsiab muag, corrugation yog siv los xyuas kom meej qhov kev faib tawm ntawm cov luminous flux raws li cov qauv tsim (± 15 degrees hauv lub dav hlau ntsug rau txhua lub teeb, thiab nyob rau hauv kab rov tav dav hlau ± 45 degrees rau nres teeb, + 80 / -45 degrees rau qhov chaw nres tsheb, thiab lwm yam).Corrugation tuaj yeem yog ob hom:
● Lens kab cim;
● Prismatic kab kawm.
Lub ntsiab lus ntawm lub lens yog tsim nyob rau hauv daim ntawv ntawm nyias concentric rings nrog ib tug prismatic (triangular) cross-section.Cov nplhaib zoo li no tsim lub lens Fresnel tiaj tus, uas, nrog qhov tsawg kawg nkaus tuab, muab qhov tsim nyog lub teeb tawg.Prismatic trace ntsiab yog ib tug neeg prisms ntawm me me, sib npaug faib rau diffuser.
Tsheb teeb diffusers tau muab faib ua ntau hom raws li lawv tsim:
● Sib cais - tus kheej diffusers rau txhua lub teeb;
● Grouped - ib hom lo ntsiab muag rau lub teeb, nyob rau hauv uas tag nrho cov rear lub teeb-sib nqus cov cuab yeej ntawm lub tsheb yog pawg;
● Kev sib xyaw ua ke - ib qho diffuser rau sab teeb thiab chav teeb teeb pom kev zoo;
● Kev sib xyaw ua ke - ib qho sib txawv diffuser rau cov teeb uas ib lub teeb ua haujlwm ob zaug ib zaug, feem ntau yog lub teeb sab nraud thiab lub teeb nres, ua ke nrog lub teeb pom kev.
Tam sim no, cais lub teeb thiab ib tug neeg diffusers rau lawv yog siv tsis tshua muaj heev, thiab txawm nyob rau hauv thaum ntxov ua qauv ntawm automotive khoom, xws li ib tug daws yuav nrhiav tau tsuas yog rau qhov chaw nres tsheb teeb.Qhov tshwj xeeb yog lub teeb rov qab tau teeb tsa rau ntau lub tsheb hauv tsev, suav nrog cov tsheb thauj khoom, thiab cov tsheb thauj khoom.
Ntawm cov neeg caij tsheb, qhov dav tshaj plaws yog pawg teeb nrog cov diffusers, muab faib ua ntau lub teeb pom kev zoo ntawm ntau yam duab thiab xim.Xws li diffusers tuaj yeem muaj txog li xya thaj tsam:
● Qhov kawg ntawm sab nraud ntawm lub tsheb yog qhov taw qhia kev taw qhia;
● Qhov ze tshaj rau qhov taw qhia kev taw qhia yog lub teeb sab;
● Nyob rau hauv txhua qhov chaw yooj yim - lub teeb nres;
● Nyob rau hauv txhua qhov chaw yooj yim (tab sis feem ntau nyob hauv qab) - lub teeb rov qab;
● Extreme nyob rau sab ntawm lub longitudinal axis ntawm lub tsheb yog lub teeb pos huab;
● Nyob rau hauv txhua qhov chaw yooj yim - reflector (reflector);
● Nyob rau sab ntawm daim ntawv tso cai muaj lub teeb daim ntawv tso cai.

Feem ntau, nyob rau hauv xws li kev sib txuas teeb, sab teeb thiab nres teeb tuaj yeem ua ke ntawm lub teeb nrog ob lub voj voog (lossis ntawm LEDs ntawm qhov sib txawv), uas muab qhov sib txawv ntawm lub teeb thaum lub tsheb txav thiab nres.Tsis tas li ntawd, nyob rau hauv cov neeg caij tsheb niaj hnub no, muaj kev xyaum tsis muaj teeb pom kev zoo nrog cov teeb pom kev zoo nrog cov teeb pom kev zoo.
Cov teeb sib xyaw nrog cov diffusers tsim nyog feem ntau yog siv rau cov tsheb thauj khoom, tsheb thauj khoom, tsheb laij teb thiab ntau yam khoom siv, nrog rau UAZ mus txog rau tus qauv Hunter.Cov teeb zoo li no yog peb hom tseem ceeb nrog cov diffusers sib txawv:
● Ob-section nrog taw qhia taw qhia thiab sab teeb;
● Ob-section nrog lub taw qhia kev taw qhia thiab ua ke sab teeb thiab nres lub teeb;
● Peb-section nrog cais taw qhia, sab teeb thiab nres teeb.
Ob-thooj teeb feem ntau muaj cov khoom sib xyaw ua ke ua los ntawm ob qhov sib txawv ntawm cov xim sib txawv, uas tso cai rau koj hloov ib nrab yog tias tsim nyog.Nyob rau hauv ob-section thiab peb-section diffusers, ib tug retroreflector tej zaum yuav muab ntxiv.
Qhov sib txawv ntawm cov diffusers yog pleev xim rau hauv cov xim uas tau teev los ntawm cov qauv:
● Chaw nres tsheb teeb - liab;
● Cov taw qhia taw qhia - dawb los yog xim daj (amber, txiv kab ntxwv);
