LED teeb sawb tam sim no yog ib qho ntawm cov teeb peb feem ntau siv.Kab lus no feem ntau piav qhia txog cov ntsiab lus tseem ceeb ntawm cov teeb pom kev zoo uas nquag siv thiab yuav ua li cas txheeb xyuas cov teeb pom kev zoo.

High voltage teeb sawb

Kev sib xyaw ntawm high voltage teeb sawb

Lub thiaj li hu ua high-voltage teeb sawb yog lub teeb sawb nrog 220V mains hwj chim input.Tau kawg, nws tsis raug tso cai txuas ncaj qha rau AC 220V, tab sis kuj yuav tsum tau txuas lub taub hau fais fab, raws li qhia hauv daim duab hauv qab no.

Cov qauv ntawm lub taub hau fais fab no yog qhov yooj yim heev.Nws yog ib qho rectifier choj pawg, uas hloov AC lub zog hluav taws xob mus rau qhov tsis zoo DC fais fab.LEDs yog cov khoom siv hluav taws xob uas xav tau tam sim no ncaj qha.

1, Flexible teeb hlaws phaj

Qhov tseem ceeb tshaj plaws yog los lo rau tus naj npawb ntawm LED thaj teeb teeb hlaws thiab tam sim no txwv cov resistors ntawm lub rooj tsav xwm hloov tau yooj yim.

Raws li peb paub, qhov voltage ntawm ib lub teeb ci LED hlaws yog 3-5 V;Yog tias ntau tshaj 60 lub teeb hlaws dai ua ke, qhov hluav taws xob tuaj yeem ncav cuag li 200V, uas yog nyob ze rau lub mains voltage ntawm 220V.Nrog rau qhov sib ntxiv ntawm kev txwv tam sim no, LED teeb hlaws phaj tuaj yeem ua haujlwm ib txwm ua tom qab kho AC fais fab tuag.

Ntau tshaj 60 lub teeb hlaws (ntawm chav kawm, muaj 120, 240, uas yog tag nrho cov kev sib txuas ua ke) yog strung ua ke, thiab qhov ntev yog ze rau ib 'meter'.Yog li ntawd, lub high-voltage teeb siv feem ntau yog txiav los ntawm ib tug meter.

Qhov kev xav tau zoo ntawm FPC yog los xyuas kom meej qhov kev thauj khoom tam sim no ntawm ib txoj hlua ntawm lub teeb strips hauv ib meter.Raws li ib txoj hlua tam sim no feem ntau yog nyob rau qib milliampere, qhov kev xav tau ntawm tooj liab thickness rau high-voltage flexplate tsis siab heev, thiab ib txheej ib txheej vaj huam sib luag yuav siv ntau dua.

2. Tus neeg xyuas pib

Cov xov hlau txuas txhua 'meter' ntawm lub teeb strips.Thaum cov xov hlau khiav tawm, qhov poob qis ntawm high-voltage DC yog qhov tsawg heev piv nrog 12V lossis 24V cov teeb hluav taws xob tsawg.Qhov no yog vim li cas lub high-voltage teeb sawb tuaj yeem yob rau 50 meters, lossis txawm tias 100 meters.Cov xov hlau embedded rau ntawm ob sab ntawm high-voltage teeb txoj siv yog siv los xa cov hluav taws xob high-voltage rau txhua txoj hlua ntawm lub teeb hloov tau yooj yim.

Qhov zoo ntawm cov hlau tseem ceeb heev rau tag nrho cov high-voltage teeb sawb.Feem ntau, high-voltage lub teeb sawb xov hlau yog ua los ntawm tooj liab xov hlau, thiab cov seem seem yog qhov loj, uas yog ntau dua piv nrog rau tag nrho cov hwj chim ntawm high-voltage teeb sawb.

Txawm li cas los xij, cov khoom siv hluav taws xob pheej yig thiab tsis tshua muaj hluav taws xob zoo yuav tsis siv cov xov tooj tooj liab, tab sis tooj liab clad aluminium xov hlau, lossis cov xaim hluav taws xob ncaj qha, lossis txawm tias cov xaim hlau.Lub ci ci thiab lub zog ntawm hom teeb ci no yog ib txwm tsis siab heev, thiab qhov tshwm sim ntawm cov xaim hluav taws xob tawm vim yog overload kuj tseem siab heev.Peb qhia cov neeg kom tsis txhob yuav cov teeb ci zoo li no.

3, Potting nplaum

Lub teeb hluav taws xob siab yog khiav ntawm cov hlau uas muaj hluav taws xob siab, uas yuav ua rau muaj kev phom sij.Kev rwb thaiv tsev yuav tsum ua kom zoo.Kev coj ua dav dav yog txhawm rau txhawm rau pob tshab PVC yas.

Cov yas zoo li no muaj lub teeb kis tau zoo, lub teeb yuag, zoo plasticity, rwb thaiv tsev thiab thermal rwb thaiv tsev.Nrog rau cov txheej txheem tiv thaiv no, lub teeb hluav taws xob siv hluav taws xob muaj zog tuaj yeem siv tau zoo, txawm tias sab nraum zoov, txawm tias cua los yog los nag.

Khawb lub blackboard!Nov yog qhov kev paub txias: vim tias qhov kev ua tau zoo ntawm pob tshab PVC yas tsis yog huab cua tom qab tag nrho, yuav tsum muaj qee qhov txo qis ntawm lub teeb ci ci.Qhov no tsis yog teeb meem.Qhov teeb meem yog tias nws kuj muaj feem xyuam rau cov xim kub ntawm lub teeb sawb, uas yog mob taub hau xim kub drift.Feem ntau hais lus, nws yuav ntab 200-300K siab dua.Piv txwv li, yog tias koj siv lub teeb hlaws nrog xim kub ntawm 2700K los ua lub teeb hlaws phaj, xim kub tom qab sau thiab sealing yuav ncav cuag 3000K.Koj ua nws nrog 6500K xim kub, thiab nws khiav mus rau 6800K lossis 7000K tom qab raug kaw.
