Kev Ntsuam Xyuas Daim Ntawv Thov Kev Ntsuam Xyuas Diodes hauv LED TV Fais Fab System

1, cov haujlwm yooj yim ntawm diodes
Ib qho Diode tsuas yog muaj li ntawm PN cov qauv sib xws ntawm P - hom semiconductor thiab n}} hom semiconductor. Nyob rau hauv qhov kev txiav txim ntawm cov voltage rau pem hauv ntej, cov kev sib tw PN me me thiab cov hluav taws xob ntws los ntawm N cheeb tsam mus rau PAR cheeb tsam, sib sau ua ntej; Nyob rau hauv qhov kev txiav txim ntawm kev thim rov qab voltage, tab sis pn hlws dav dav, tabkaum ntws ntawm cov hluav taws xob thiab kev rov qab ua ib qho kev thim rov qab me me. Qhov kev coj ua tsis zoo no ua rau muaj kev coj ua zoo rau kev coj ua thiab qhov ntau ntawm cov kev tawm tsam tam sim no, thiab yog siv dav dav, thiab yog kev nrhiav kom pom tseeb, thiab lwm daim teb.
Rectification Functionic muaj nuj nqi: Hloov pauv kev hloov tshiab rau hauv kev ncaj qha tam sim no los muab lub zog ruaj khov rau lub TV.
Kev Nrhiav Ua Haujlwm: Extract tseem ceeb tsawg - zaus ntawm high- cov cim qhia kom ua tiav cov cim hluav taws xob hauv TV.
Voltage ruaj khov ua haujlwm: nws ua si tsis siv neeg hluav taws xob txoj cai lub luag haujlwm hauv Circuit Court, tiv thaiv lub TV los ntawm kev hloov pauv hloov tshiab.
2, Daim Ntawv Thov Tshwj Xeeb Ntawm Diodes hauv LED TV Fais fab
Hauv LED TV Fais koob system, daim ntawv thov ntawm dodes yog mas yog los ntawm cov hauv qab no:
Rectifier Circuital
LED TV fais fab system yuav xav tau hloov AC Fais Fab rau DC lub zog rau DC lub zog rau lub LED Backlight Module thiab lwm lub voj voog. Diodes ua lub luag haujlwm tseem ceeb hauv Rectifier circubits, feem ntau yog siv cov choj ib nrab ntawm dodes, thiab ces du lawv los ntawm kev lim dej ruaj khov.
Kev Tsav Tsheb tas sim
Qhov ci ci ntawm LED lub teeb ncaj qha rau qhov tam sim no ntws mus rau nws, yog li kev tsav tsheb tam sim no yog tus yuam sij rau kev ua kom ruaj khov LED lub teeb pom kev zoo. Ib qho kev them nyiaj tam sim no Los ntawm kev sib txuas tas li tam sim no diodes nyob rau hauv series, tam sim no ntawm LED tuaj yeem tswj tau zoo, ua kom pom kev ruaj khov kho thiab txuas ntxiv txoj kev pabcuam lub neej.
Tus qauv ua haujlwm ntawm Diode tas li yog thaum thim rov qab voltage nce mus rau qhov muaj txiaj ntsig punctions, thiab lub pinch tawm ua rau qhov tam sim no yuav luag nyob ntawm cov ntawv thov siv hluav taws xob, ua tiav ib qho kev cuam tshuam tam sim no. Txawm li cas los xij, tas mus li tam sim no ddays tsis zoo tshaj plaws Cheebtsam, thiab lawv tam sim no tseem yuav nce nrog voltage, thaum lub sij hawm kub kuj yuav tsum tau txiav txim siab. Yog li ntawd, hauv cov ntawv thov siv tau, kev them nyiaj ntsuas kub feem ntau tau txais los txhim kho qhov tseeb ntawm qhov tam sim no.
Voltage stabilizing Circuitizing
Zener desies muaj cov kev cai tshwj xeeb voltage thiab tuaj yeem ruaj khov tswj cov hluav taws xob tawm hauv qee qhov ntau. Hauv LED TV Fais fab, voltage stabilizing stigilizing cov hluav taws xob voltilities los ua kom ntseeg tau tias ruaj khov hloov los ntawm kev puas tsuaj rau kev puas tsuaj thiab lwm yam kev sib tw.
Kev Tiv Thaiv Circuit Court
Uiodes tseem muaj dav nyob hauv kev tiv thaiv kev tiv thaiv, xws li kev tiv thaiv hluav taws xob ntau dhau los yog txiav tawm ntawm Circuit Court, thiab tiv thaiv lub Circuit Court, thiab tiv thaiv lub system los ntawm kev puas tsuaj.
3, qhov zoo thiab cov kev sib tw ntawm dodes nyob rau hauv LED TV zog
Qhov Zoo:
Ua tau zoo thiab lub zog - txuag: deaties muaj cov yam ntxwv ntawm cov kev siv hluav taws xob tsis muaj zog, uas pab kom txo lub zog ntawm LED TV zog.
Zoo ruaj ruaj: tus diode tuaj yeem muab cov khoom siv tam sim no thiab voltage tso tawm, ua kom ruaj khov LED lub teeb pom kev zoo thiab txhim kho TV zoo.
Kev ntseeg siab: Diodes muaj kev ntseeg siab thiab kev pabcuam lub neej, uas yuav pab txuas rau lub neej pabcuam ntawm LED TVs.
Sib tw:
Cua sov dissipation teeb meem: cov diode generates tshav kub lub sijhawm ua haujlwm thiab yuav tsum tau muaj cua sov dissheated thiab puas.
Tus nqi teeb meem: Kev ua tau zoo donges muaj siab dua tus nqi siab dua, uas nce tus nqi ntawm LED TV zog.
Kev sib tw kev sib tw: nrog kev txhim kho kev nruam ntawm LED TV thev naus laus zis, kev ua tau zoo dua qub tau tsim kev ua lag luam xav tau.
