Yog vim li cas koj T5 LED Tube Overheats thaum kuaj (Thiab yuav kho nws li cas)

Koj tau yuav hom B tshiab, ib zaug - xaus T5 LED raj, tsim los rau kev sib txuas ncaj qha AC. Cov specs hais tias "AC85-265V," yog li koj lob qee cov hlua khi, txuas rau koj lub zog 120V, thiab ... tsis pub dhau feeb, lub raj yuav kub hnyiab. Yuav ua li cas? Puas yog lub raj faulty?

Tsis txhob muab koj lub teeb tshiab tso tseg. Hauv ntau dua 99% ntawm cov xwm txheej zoo li no, qhov teeb meem tsis yog lub raj LED nws tus kheej, tab sis qhov yuam kev tseem ceeb hauv txoj kev sim. Phau ntawv qhia no yuav kuaj xyuas tus neeg ua txhaum tseeb thiab muab kev daws teeb meem.

Lub hauv paus ua rau: Nws tsis yog Tube, Nws yog Kev Xeem

Qhov xwm txheej tau piav qhia txog- overheating thaum lub sij hawm kuaj kab nuv ntses- yog ib rooj plaub ntawm"Lub Bottleneck Effect."Qhov teeb meem yog tsis nyob rau hauv lub raj ntawm kev sib xyaw tsav tsheb, tab sis ntawm qhov chaw uas koj qhia lub hwj chim:tus nquab clips lawv tus kheej.

Thaum koj siv cov hlua khi ncaj qha rau ntawm lub raj lub pins, koj tsim lub cua daj cua dub zoo tshaj plaws rau kev tsim kom muaj cua sov ntau vim yog ob yam tseem ceeb:

1. Kev tiv tauj loj heev

Ib tug tiag tiag -Lub ntiaj teb Analogy:Xav txog tej yam sim haus ib tug tuab milkshake los ntawm ib tug heev nyias, pinched straw. Koj yuav tsum nqus ntau zog, thiab koj lub dag zog hloov mus ua cua sov hauv koj lub plhu. Ib yam li ntawd, hluav taws xob ntsib kev tiv thaiv thaum raug yuam los ntawm kev sib txuas tsis zoo.

Kev Tshawb Fawb:Hauv kev teeb tsa kom raug, lub raj tso rau hauv lub qhov (socket) nrog dav, caij nplooj ntoos hlav- thauj cov neeg sib cuag, tsim kom muaj qhov loj, qis- tsis kam sib txuas. Alligator clips, txawm li cas los xij, ua ibtaw tes tiv tauj lossis ib kab me me hunrog cov pins puag ncig. Qhov chaw me me no tsim kom muaj hluav taws xob tsis zoo.

Kev ntsuas kub:Raws li Joule txoj cai lij choj (P =} I²R), lub zog (thiab yog li cua sov) tsim los ntawm ib qho taw tes yog proportional rau square ntawm tam sim no thiab qhov tsis kam.

Rau 20W raj ntawm 120V, tam sim no (I) yog li 0.17A.

Ib qho kev sib txuas tsis zoo ntawm tus kab laug sab tuaj yeem qhia tau yooj yim5-10 ohms ntawm tsis kam (R).

Fais fab Dissipated li Thaum tshav kub kub=(0.17A)² * 5 Ω =~ 0.14 W.
Cov cua sov no tsis kis tawm; nws tau tsom mus rau thaj tsam me me ntawm qhov clip thiab tus pin, ua rau qhov chaw tshwj xeeb kom sov sai heev -feem ntau mus rau qhov kub thiab txias txaus kom hlawv daim tawv nqaij. Cov cua sov no ces ua rau tus pin thiab mus rau hauv lub raj lub tsev, tsim qhov kev xav tsis tseeb tias tag nrho cov raj yog "overheating."

2. Tsis ruaj tsis khov tam sim no

Cov kev sib txuas tsis zoo tuaj yeem ua rau micro-arcs thiab sparks, uas yog me me xob laim bolts uas ua rau muaj kev kub ntxhov, hauv cheeb tsam kub, ntxiv rau qhov teeb meem.

Kev daws teeb meem: Yuav ua li cas kuaj kom raug

Txhawm rau ntsuas kev noj qab haus huv ntawm koj lub T5 LED raj, koj yuav tsum tshem tawm qhov sib txawv ntawm kev sib cuag tsis zoo. Ntawm no yog cov kauj ruam -los ntawm - kauj ruam qhia.

Txoj Kev 1: Tus Qauv Kub (siv lub teeb tuav)

Qhov no yog tib txoj kev uas rov ua dua tshiab tiag tiag - lub ntiaj teb no.

Yam Koj Yuav Tsum Tau:

Ib tug qub los yog spare T5 teeb tuav (socket).

Ob lub xov hlau nrog cov kab nuv ntses ntawm ib kawg.

Koj lub zog AC.

Txheej txheem:

Hlau tus tuav:Txuas koj ob txoj hlua khi hlua khi mus rau lub terminals ntawm T5 lub teeb tuav.

Nruab Tube:Ruaj ntseg snap lub T5 LED raj rau hauv lub thawv. Qhov no ua kom dav dav, nws yog xim hlau sib cuag, ib yam li hauv kev teeb tsa zaum kawg.

Siv lub zog:Txuas lwm qhov kawg ntawm cov xov hlau rau koj qhov 120V AC qhov chaw.

Saib:Cia lub raj xa mus rau 15-20 feeb. Hauv kev teeb tsa no, lub raj yuav tsum tsuas yog uasov rau qhov kov (feem ntau 40-50℃/ 104-122℃F), tsis scalding kub. Yog hais tias nws tseem overheats, koj yuav muaj faulty raj.

Txoj Kev 2: Txhim Kho Alligator Clip Test (yog tias tsis muaj tus tuav)

Yog tias koj yuav tsum siv cov clips, ua cov kev ceev faj tseem ceeb no txhawm rau txhim kho kev sib txuas.

Txheej txheem:

Ntxuav cov Pins:Siv isopropyl cawv thiab paj rwb swab kom huv si huv cov hlau pins ntawm ob sab ntawm lub raj. Tshem tawm cov roj tsis pom, cov khib nyiab, lossis oxidation.

Xyuas kom meej tias "Bite":Siv cov- cov kab nuv ntses zoo nrog cov hniav ntse, huv si. Clamp lawv rau ntawm tus pins nrog lub zog tseem ceeb kom ua kom qhov chaw sib cuag tau zoo tshaj plaws.

Kov qhov chaw zoo:Tom qab lub hwj chim rau ib feeb (siv ceev faj!), ua tib zoo kov lubAlligator clip nws tus kheejthiab covpuag ntawm tus pin hlau. Yog tias cov no scalding kub tab sis lub raj lub cev txias dua, koj tau lees paub qhov kev tiv tauj - teeb meem tiv thaiv.

Yog vim li cas Tube's Driver zoo li zoo

Koj lub raj "AC85-265V" muaj lub zog hloov hluav taws xob sab hauv (tus tsav tsheb) tsim los tswj cov kev tawm tswv yim dav. Ntawm 120V, nws zoo nyob rau hauv nws lub qhov rais ua haujlwm.

Tsis zoo li qub:Txawm tias tus neeg tsav tsheb zoo tshaj plaws yog 85-90% ua haujlwm tau zoo. Rau 20W raj, qhov no txhais tau tias 2-3W ntawm cov cua sov yog tsim los ntawm tus neeg tsav tsheb thiab dissipated raws tag nrho ntev ntawm lub raj-qhov no yogib txwm thiab nyab xeeb.

Qhov Tseem Ceeb Distinction:Cov cua sov los ntawm qhov tsis zoo ntawm tus pas nuv ntses clip txuas (0.5W - 1W+) yog tsom rau ntawm thaj chaw minuscule, tsim kom muaj qhov txaus ntshai "kub qhov chaw." Cov neeg tsav tsheb ib txwm muaj cua sov yog kis tawm, ua rau muaj kev xav zoo, sov so.

Summary and Final Recommendation

Hauv kev xaus, tsis txhob txiav txim siab koj T5 LED raj los ntawm kev sim nrog cov kab nuv ntses.Lub overheating koj tab tom soj ntsuam yog yuav luag ib yam dab tsi ntawm kev tiv thaiv siab tiv thaiv nyob rau hauv txoj kev ntawd. Los ntawm kev siv tus qauv teeb lub teeb rau kev sim, koj tsim qhov chaw ncaj ncees thiab muaj tseeb los txheeb xyuas lub raj qhov kev ua tau zoo thiab txaus siab rau lub zog- txuag cov txiaj ntsig ntawm koj lub teeb pom kev tshiab LED.
