Yuav ua li cas los daws qhov teeb meem Thaum tshav kub kub dissipation ntawm LED hnub so teeb

Cov neeg siv khoom feem ntau nug, lub teeb loj npaum li cas thiab LED hnub so lub teeb tsim nyog rau dai ntawm LED txoj kev teeb ncej? Qhov loj npaum li cas ntawm LED hnub so teeb tseem tuaj yeem dai rau ntawm 6-meter ntev LED ncej? Tam sim no LED hniav teeb manufacturers muab koj ib daim ntawv qhia txog yuav ua li cas siab txoj kev teeb ncej yog haum rau dai LED teeb thiab LED hnub caiv teeb.

Cov neeg tau nce siab rau qhov kub dissipation ntawm LED hnub so teeb. Qhov no yog vim lub teeb attenuation lossis lifespan ntawm LED hnub so teeb yog ncaj qha ntsig txog lawv qhov kub thiab txias. Yog tias cov cua kub tsis zoo, qhov sib txuas kub yuav siab dua thiab lub neej yuav luv. Raws li txoj cai Arrhenius, rau txhua txhua 10 degree txo qis hauv qhov kub thiab txias, lub neej yuav raug ncua los ntawm ob zaug. Los ntawm kev sib raug zoo ntawm lub teeb lwj thiab qhov kub thiab txias tso tawm los ntawm CREE lub tuam txhab, nws tuaj yeem pom tau tias yog tias qhov ntsuas kub sib txuas tuaj yeem tswj tau ntawm 65 ° C, lub neej ntawm nws lub teeb lwj mus txog 70 feem pua ​​tuaj yeem ncav cuag 100000 teev! Qhov no yog lub neej expectancy uas tib neeg npau suav ntawm, tab sis nws puas tuaj yeem ua tiav? Yog lawm, tsuav nws tuaj yeem daws nws qhov teeb meem kub kub, nws muaj peev xwm ua tiav nws! Hmoov tsis zoo, qhov tseeb hluav taws kub dissipation ntawm LED teeb yog deb ntawm qhov xav tau tam sim no! Yog li ntawd, lub neej ntev ntawm LED hnub so teeb tau dhau los ua qhov teeb meem loj cuam tshuam rau lawv cov kev ua tau zoo, yog li nws yuav tsum tau ua tiag tiag!

Ntxiv mus, qhov sib txuas kub tsis tsuas yog cuam tshuam rau lub neej ntev, tab sis tseem cuam tshuam ncaj qha rau lub sijhawm luv luminescence efficiency. Yog tias qhov luminosity yog 100 feem pua ​​​​ntawm qhov sib txuas ntawm qhov kub ntawm 25 degrees, ces thaum qhov sib txuas kub nce mus rau 60 degrees, qhov luminosity tsuas yog 90 feem pua. Thaum qhov kub ntawm qhov sib txuas yog 100 degrees, nws poob rau 80 feem pua. Ntawm 140 degrees, tsuas yog 70 feem pua ​​tuaj yeem pom, kev txhim kho cov cua sov thiab tswj qhov kub ntawm qhov sib txuas yog qhov tseem ceeb heev.
