Yuav ua li cas kom raug nrog LED lub teeb siv thaum tshav kub kub dissipation
In our daily life, many places will use LED light strip. Like other luminaries, heat is generated if the strip is guided for a long time. So, how to deal with the lamp belt heating problem, let's have a look.
Kev kho kom raug ntawm LED sawb kub dissipation 1. Kev sib txuas hom
Feem ntau siv lub teeb bar specifications yog 12V thiab 24V. 12V yog 3 series thiab parallel qauv, 24 V yog 6 series thiab ntau cov qauv sib luag. Txhua hom sawb yog tshwj xeeb vim yog kev sib txuas thiab kev siv ntawm LED strips. Hauv kev tsim, qhov ntev ntawm lub sijhawm sib txuas yog cuam tshuam nrog qhov dav ntawm lub voj voog thiab lub thickness ntawm cov ntawv ci tooj liab. Lub zog ntawm tam sim no kuj muaj feem xyuam rau tus ntoo khaub lig- ntu ntu ntawm tus neeg xyuas pib. Yog tias qhov kev sib txuas ntev tshaj qhov tam sim no uas cov xaim tuaj yeem tiv taus thaum lub sij hawm xaim, lub sawb yuav raug cua sov. Yog tias lub sijhawm cua sov ntev dhau lawm, nws yuav cuam tshuam rau lub neej ntawm lub rooj tsav xwm Circuit Court thiab lub teeb siv.
Kev kho kom raug ntawm LED sawb cua sov dissipation 2. qhov kub thiab txias ntawm Circuit Court yog siab dhau
LED sawb yog ib tug series thiab parallel qauv. Thaum ib lub voj voog luv luv - Circuit Court, qhov hluav taws xob ntawm lwm cov hlaws hauv tib lub teeb yuav nce, thiab qhov ci ntsa iab ntawm cov hlaws yuav nce ntxiv, uas yuav ua kom muaj cua sov sib xws, tshwj xeeb tshaj yog 5050 band. Thaum ib tug ntawm lawv luv luv Circuit Court nyob rau hauv lub nti Circuit Court, tam sim no ntawm lwm lub teeb hlaws yuav tsum muab ob npaug rau, thiab brightness ntawm lub teeb hlaws yuav ua super ci thiab super siab, thiab cov cua kub tso tawm yuav dhau mus thiab yuav nce sai heev. , qhov hnyav yuav ua rau lub rooj tsav xwm hluav taws xob hlawv.
Kev kho kom raug ntawm LED sawb tshav kub dissipation 3, xyuas cov tsos
However, these problems are usually not noticed because the short circuit does not affect the normal lighting of the lamp bar. Usually, testers only notice if the bead can be turned on. They rarely check for brightness anomalies or perform electrical tests instead of visual checks, which often ignore the problem. That's why some lights get hot once they're turned on.
Kev kho kom raug ntawm LED sawb kub dissipation 4, tag nrho cov thickness ntawm lub rooj tsav xwm Circuit Court
First, the wiring in the circuit should be as wide as possible and the distance between the wires should be 0.5mm. The remaining space should be full. The thickness of the copper foil shall be as thick as possible without violating the customer's requirements for the total thickness of the circuit board.
5. Ua tib zoo saib xyuas cov ntsiab lus ntawm kev teeb tsa
Tom qab ntawd, thaum luam ntawv solder paste thaum lub sijhawm tsim khoom, sim tsis txhob tsim cov tin tas li ntawm cov ntaub so ntswg kom tsis txhob luv luv Circuit Court ntawm solder vim tsis zoo luam ntawv. Kev saib xyuas yuav tsum tau them rau cov ntsiab lus ntawm kev teeb tsa kom tsis txhob luv luv Circuit Court. Xyuas thaj chaw ua ntej reflow thiab xyuas cov tsos tom qab reflow kom paub tseeb tias lub teeb sawb tsis luv -circuiting, ces ua hluav taws xob kuaj. Thaum kuaj xyuas dua, thov ua tib zoo saib seb qhov ci ntawm lub teeb hlaws puas txawv txav.
Cov saum toj no yog kev sib qhia txog yuav ua li cas kom raug nrog cov cua kub dissipation ntawm LED teeb sawb. Kuv ntseeg tias tom qab nyeem cov ntsiab lus saum toj no, peb muaj kev nkag siab txog qhov kev paub no. Yog tias cov xwm txheej zaum kawg tso cai, thaum siv lub teeb sawb, peb tuaj yeem cia lub teeb muaj sijhawm ntau lub sijhawm, kom tsis txhob muaj cua sov los ntawm lub teeb sawb ua haujlwm ntev. Tau kawg, kev siv LED teeb txoj siv yog qhov tsis muaj cua sov, tsuav yog peb them sai sai rau tsis ua kom luv luv Circuit Court thiab overwork, peb tuaj yeem zam qee qhov xwm txheej tshwm sim los ntawm overheating. Tsis txhob npog sab nraud ntawm lub teeb siv kom ntau li ntau tau, ua rau tsis muaj cua sov dissipation. Yog tias koj xav paub ntau ntxiv txog LED teeb sawb cov ntaub ntawv kub dissipation, koj tuaj yeem mus rau cov neeg siv khoom kev sib tham.
