Yuav daws qhov teeb meem cua sov ntawm LED teeb strips li cas

Yog vim li cas thiab kev daws teeb meem rau cua sov ntawm LED teeb strips

Peb feem ntau siv cov khoom siv LED hauv peb lub neej, thiab LED lub teeb strips tau siv dav hauv kev kho kom zoo nkauj thiab kho kom zoo nkauj hauv ntau qhov chaw hauv xyoo tas los no. Feem ntau, lawv yuav tsum tau ua haujlwm ntev, uas yuav ua rau lawv raug puas tsuaj vim muaj hluav taws xob mus sij hawm ntev. ua npaws. Yog li dab tsi ua rau kub taub hau thiab yuav daws tau li cas tom qab kub taub hau? Wb sib tham txog lawv ua ke.

1. Ua rau cua sov ntawm lub teeb strips

Muaj ntau qhov laj thawj rau qhov kub ntawm lub teeb sawb, nrog rau cov hauv qab no:

1. Ua los ntawm LED cua sov

LED yog lub teeb txias qhov chaw uas theoretically tsis ua kom sov. Txawm li cas los xij, nyob rau hauv cov ntaub ntawv siv, vim tsis zoo hluav taws xob hloov dua siab tshiab thiab photoelectric conversion efficiency, ib tug npaum li cas ntawm cov cua sov yuav raug generated rau ib tug tej yam, ua rau lub teeb sawb kom sov.

2. Tsis zoo cua sov dissipation ntawm lub teeb sawb

Tsis zoo cua sov dissipation ntawm lub teeb sawb kuj yog ib qho tseem ceeb vim li cas rau lub tshav kub ntawm lub teeb sawb. Kev tsis zoo ntawm cov hluav taws xob hluav taws xob tsis zoo yog tshwm sim los ntawm ntau yam xws li kev xaim tsis tsim nyog, kev tsim hluav taws xob tsis zoo, lossis thaiv cov dab dej kub. Thaum tshav kub dissipation tsis zoo, lub teeb sawb yuav overheat, ua rau lub neej luv luv ntawm lub teeb sawb.

3. Lub teeb sawb yog overloaded

Overloading ntawm lub teeb strips kuj yog ib qho ntawm cov laj thawj vim li cas lub teeb strips sov. Thaum tam sim no lub teeb sawb tiv taus loj dhau lawm, nws yuav ua rau lub teeb sawb dhau los, ua rau cov khoom muaj hnub nyoog, ua rau luv luv Circuit Court, qhib circuits, thiab lwm yam.

1. Circuit Court nam: Feem ntau siv voltage specifications ntawm LED teeb strips yog 12V thiab 24V. 12V yog 3-txoj hlua ntau-channel sib luag qauv, thiab 24V yog 6-txoj hlua ntau-channel sib luag qauv. LED lub teeb strips yog siv los ntawm kev sib txuas ntau lub teeb hlaws pawg. Qhov tshwj xeeb ntev ntawm lub teeb strips uas tuaj yeem txuas nrog muaj ntau yam ua rau qhov dav ntawm Circuit Court thiab thickness ntawm cov ntawv ci tooj liab thaum tsim. Qhov kev siv tam sim no uas ib lub teeb sawb tuaj yeem tiv taus yog cuam tshuam rau thaj tsam ntawm kab ntawm kab. Koj yuav tsum xyuam xim rau qhov no thaum txhim kho lub teeb sawb. Yog tias qhov txuas ntev ntawm lub teeb sawb ntau tshaj qhov tam sim no nws tuaj yeem tiv taus thaum lub sijhawm teeb tsa, tom qab ntawd lub teeb sawb yuav tshwm sim thaum ua haujlwm, nws yuav twv yuav raug hu ua cua sov vim yog overloaded tam sim no, uas yuav ua rau lub Circuit Court board zoo heev thiab txo cov kev pab cuam lub neej ntawm lub teeb. strip.

2. Kev tsim khoom: LED lub teeb strips yog tag nrho cov qauv sib txuas. Thaum ib qho luv luv Circuit Court tshwm sim hauv ib pab pawg, qhov voltage ntawm lwm pab pawg ntawm lub teeb sawb yuav nce, thiab cov cua sov ntawm LED kuj yuav nce raws li. Qhov tshwm sim no tshwm sim feem ntau hauv 5050 teeb sawb. Thaum ib qho nti ntawm 5050 teeb sawb luv luv, qhov tam sim no ntawm lub teeb luv luv hlaws yuav muab ob npaug rau, thiab 20mA yuav dhau los ua 40mA, thiab qhov ci ntawm lub teeb hlaws yuav raug txo. Nws yuav tau ci dua thiab tib lub sijhawm ua rau muaj cua sov hnyav, qee zaum hlawv lub rooj tsav xwm hauv Circuit Court li ob peb feeb. Ua rau lub teeb ci LED tau muab pov tseg. Txawm li cas los xij, qhov teeb meem no yog qhov tsis meej, thiab feem ntau nws tsis zoo li yuav pom, vim tias luv luv tsis cuam tshuam rau lub teeb pom kev zoo ntawm lub teeb sawb, yog li ob peb tus neeg xyuas nws tsis tu ncua. Yog tias tus neeg kuaj xyuas tsuas yog kuaj xyuas seb lub teeb ci ntsa iab puas tawm lub teeb thiab tsis saib xyuas seb qhov ci ntawm LED yog qhov txawv txav, lossis tsuas yog kuaj xyuas qhov tsos yam tsis tau kuaj pom tam sim no, yog vim li cas vim li cas LED heats li feem ntau yuav tsis quav ntsej, uas. yuav ua rau Ntau tus neeg siv hais tias lub teeb strips ua kub tab sis nrhiav tsis tau vim li cas.

Kev daws:

1. Xaiv lub teeb sawb nrog kev ua kom sov zoo

Thaum muas lub teeb sawb, koj tuaj yeem xaiv lub teeb sawb nrog kev ua haujlwm zoo ntawm cov cua sov, uas tuaj yeem txo qhov teeb meem tsis zoo ntawm cov cua sov dissipation ntawm lub teeb sawb thiab tiv thaiv lub teeb sawb los ntawm overheating thiab ua rau tsis ua hauj lwm.

2. Ua kom zoo thermal dissipation tsim rau lub teeb sawb

Rau qee qhov chaw uas yuav tsum tau siv lub sijhawm ntev, cov nyhuv tshav kub ntawm lub teeb ci tuaj yeem txhim kho los ntawm kev ntxiv cov radiators lossis cov dab dej kub. Cov cuab yeej hluav taws xob hluav taws xob kuj tseem tuaj yeem tsim nyob rau hauv lub teeb sawb tsim los txhim kho lub peev xwm ntawm lub teeb hluav taws xob kom zoo.

3. Tsis txhob overloading lub teeb sawb

Thaum siv lub teeb strips, sim kom tsis txhob overloading, xaiv cov teeb pom kev zoo thiab cov khoom siv hluav taws xob, thiab ua cov xaim tsim nyog kom tsis txhob overloading lub teeb ntev ntev.

1. Kab tsim:

Xav txog qhov kev ua siab ntev tam sim no, lub voj voog yuav tsum tau tsim los ua kom cov xaim hluav taws xob ntau li ntau tau. Qhov sib nrug ntawm 0.5 hli yog txaus. Nws yog qhov zoo tshaj los sau qhov seem ntawm qhov chaw. Thaum tsis muaj cov kev cai tshwj xeeb, lub thickness ntawm cov ntawv ci tooj liab yuav tsum tuab li ua tau, feem ntau 1 ~ 1.5 OZ. Yog tias lub voj voog tsim tau zoo, cov cua sov ntawm LED lub teeb sawb yuav raug txo kom tsawg.

2. Cov txheej txheem ntau lawm:

(1) Thaum vuam lub teeb, sim tsis txhob cia cov tin sib txuas ntawm cov ntaub qhwv kom tsis txhob vuam luv luv los ntawm kev luam ntawv tsis zoo.

(2) Lub teeb sawb kuj tseem yuav tsum zam kev luv luv thaum patching, thiab sim sim ua ntej siv.

(3) Ua ntej reflow, ua ntej kos txoj hauj lwm thaj, thiab tom qab ntawd ua reflow.

(4) Tom qab reflow, yuav tsum tau kuaj pom. Tom qab paub tseeb tias tsis muaj luv luv Circuit Court nyob rau hauv lub teeb sawb, ua ib qho kev ntsuas hluav taws xob. Tom qab fais fab tuag, ua tib zoo saib seb lub teeb ci LED yog qhov txawv txav los yog tsaus ntuj. Yog tias muaj, kev daws teeb meem yuav tsum tau ua.

Kab lus no txheeb xyuas cov laj thawj rau cov cua sov ntawm lub teeb strips thiab tawm tswv yim los daws cov teeb meem cua sov ntawm lub teeb strips. Peb cia siab tias nws tuaj yeem pab txhua tus neeg siv tau zoo dua thiab xaiv lub teeb strips thiab zam kev ua tsis tiav los ntawm overheating ntawm lub teeb strips.
