1W 3W High power coj kub ceev ceev ceev thaum siv
High-power LED teeb hlaws yog cov khoom rhiab heev, ntawm cov cua kub dissipation thiab kev ntseeg siab yog yam uas cuam tshuam rau daim ntawv thov ntawm lub zog hluav taws xob LED teeb hlaws. Yog li ntawd, txhawm rau kom ntseeg tau tias kev ua haujlwm ib txwm muaj ntawm lub zog loj LED teeb hlaws, muaj cov hauv qab no:
1. Cov kev xav tau ntawm lub dab dej kub: aluminium lossis tooj liab kub dab dej nrog fins yuav tsum tau;
2. Kev siv hluav taws xob zoo ntawm thaj chaw: Rau 1W high-power LED teeb hlaws, tag nrho cov cua sov dissipation saum npoo yuav tsum yog ≥50-60 square centimeters, thiab sim xyuas kom meej tias qhov kub ntawm lub dab dej kub tsis tshaj 60. °C.
3. Kev sib txuas txoj kev: Thaum txuas lub high-power LED teeb hlaws substrate thiab lub dab dej kub, xyuas kom meej tias ob qhov chaw sib cuag yog tiaj tus thiab nyob rau hauv kev sib cuag zoo.
1-3W siab zog coj nti
Qhov teeb meem tseem ceeb hauv kev siv lub zog loj LED teeb hlaws yog qhov teeb meem kub:
1. Kev ua hauj lwm tam sim no ntawm high-power LEDs yog ntau dua li qhov taw qhia LEDs, thiab lub zog hloov hluav taws xob kuj tseem siab dua, yog li nws yooj yim kom tau kub, yog li yuav tsum tau them nyiaj tshwj xeeb rau cov cua sov dissipation.
2. Thaum siv ib qho 1W teeb hlaws, txawm tias nws yog cov teeb pom kev zoo sab hauv tsev xws li cov teeb ci qab nthab, cov teeb tsom teeb lossis cov teeb pom kev sab nraum zoov xws li cov teeb pom kev, thermal paste yuav tsum tau siv. Txhawm rau txuag kev ua haujlwm, qee cov tuam ntxhab siv tib lub 1W teeb hlaws. Thaum tsis siv thermal paste, solder lub teeb hlaws ncaj qha, uas yuav yooj yim hlawv lub teeb hlaws vim tsis muaj cua sov dissipation.
3. Thaum ib lub teeb hlaws siv rau 3W, qhov tam sim no yuav tsum tsawg li tsawg tau. Yog tias koj yuav tsum siv lub zog loj dua tam sim no, nws tuaj yeem siv txog li 450MA, thiab yog tias nws siv rau cov teeb pom kev hauv tsev, cov cua sov dissipation xav tau kev saib xyuas tshwj xeeb. Cov txheej txheem ntau lawm Yuav ua li cas yog qhov zoo heev.
4. Sim tsis txhob solder ib lub teeb hlaws los ntawm reflow soldering, vim hais tias lub PC lens ntawm lub teeb hlaws feem ntau tsis tuaj yeem tiv taus qhov kub siab tshaj 230 degrees, thiab txawm tias lub lens PC tuaj yeem tiv taus qhov kub thiab txias, cov kua nplaum puv hauv lub teeb hlaws yuav kub. nce ntawm qhov kub thiab txias. Kev nthuav dav thiab kev cog lus ua rau cov hlau kub tawg thiab cov hlaws teeb tau raug puas tsuaj heev.
5. Thaum siv lub teeb sib xyaw ua ke, koj yuav tsum tau them sai sai rau cov cua kub dissipation. Thaum kho qhov sib xyaw ua ke ntawm lub teeb, koj yuav tsum siv cov roj thermal roj. Tsis txhob siv cov roj pleev xim dawb vim tias cov thermal conductivity ntawm cov dawb tsuas yog kwv yees li 1.2.
