Kev ceev faj rau cov cua kub dissipation ntawm coj high-power LED nti
Led high-power coj nti yog ib yam ntawm LED teeb hlaws. Piv nrog rau lub hwj chim qis LED teeb hlaws, coj lub hwj chim loj teeb hlaws muaj zog dua, ci ntsa iab thiab tus nqi siab dua. Lub teeb hluav taws xob qis LED cov hlaws muaj qhov ntsuas tam sim no ntawm 20mA, thiab cov uas muaj qhov ntsuas tam sim no siab dua 20mA tuaj yeem suav tias yog lub zog siab.
Led High-power coj nti
Kev ceev faj rau cov cua kub dissipation ntawm high-power LED nti:
1. Kev xav tau ntawm lub dab dej kub.
Cov tsos mob thiab cov khoom siv: Yog tias cov kev cai sealing ntawm cov khoom tiav tsis siab, nws tuaj yeem ncaj qha convection nrog cov huab cua sab nraud. Nws raug nquahu kom siv finned aluminium lossis tooj liab cua sov dab dej.
2. Qhov zoo ntawm tshav kub dissipation thaj tsam:
Rau 1W high-power LED dawb lub teeb (lwm cov xim yog qhov zoo ib yam), peb lub tuam txhab pom zoo tias tag nrho cov cua sov dissipation saum npoo ntawm lub dab dej kub yog ≥50-60 square centimeters.
3. txoj kev sib txuas:
Thaum txuas lub high-power LED aluminium substrate thiab lub dab dej kub, thov xyuas kom meej tias ob qhov chaw sib cuag yog tiaj tus thiab nyob rau hauv kev sib cuag zoo. Txhawm rau ntxiv dag zog rau kev sib txuas ntawm ob qhov chaw sib cuag, nws raug nquahu kom coated rau hauv qab ntawm LED aluminium substrate los yog saum npoo ntawm lub dab dej kub nrog ib txheej ntawm thermal roj (thermal conductive silicone roj) Thermal conductivity ≥3.0W / mk ), thermally conductive silicone roj yuav tsum tau thov tusyees thiab nyob rau hauv ib tug tsim nyog tus nqi, thiab ces tsau nrog screws.
