Muaj hwj huam LED txoj kev teeb lub cua txias dlaws

Yangzhou qaim hnub ci dlaws Co., Ltd | Updated: Aug 04, 2015

Kev txiav txim siab coj cog teeb pom kev zoo kev siv tshuab ob peb tseem ceeb, thermal tsim yog ib tug tseem ceeb heev tshuab, tab sis tseem txwv tsis pub nws saib ib qhov ntawm cov lug siv rua kev mus. Ua txhais, thermal tsim yuav ncaj qha seb cov LED cog teeb pom kev zoo kev zoo thiab disadvantages raws li daim ntawv thov sij yuav ncav qhov kawm tau zoo.

High-power LED thermal tov

Fais fab LED yog roos LED Hoobkas teeb glow yooj yim twg, tam sim no uas nti fais p lub teeb conversion efficiency yog tsawg kawg, tsuas 15% ~ 20%, nti ntawm lub cev me me rau 1 ~ 6125 mm 2, chaw ceev me me, hwj huam thiab sab nraud loj, los noj cov hwj huam rau tus 80% ~ 85% yuav conversion kub thiab tau faib hauj lwm, thiab nti ntawm kub lawm yuav tsum value Shi , ntau glow wavelength kuj sib txawv thiab ntev, xim liab neeg tsiv, yuav raug coj mus khis tawm lub teeb efficiency declined thiab siv lub neej txo, nug. Vim li no, kom muaj txoj kev siv cov high-power LED zoo, tshav kub dissipation yog thawj ntawm txhua yam tseem ceeb heev teeb meem yuav tsum solved.

Ob tug, lub neej luv LED hlws ris kub thiab luminous flux,

Qhov ntev ntawm lub neej raws li tus yam ntxwv LED muaj hwj huam, nws hlws ris kub thiab luminous flux ntawm tus loj, me, muaj ib tug tib neeg nws nyiam.

Raws li cov LED nti hlws ris kub tsub kom, nws tso zis luminous flux poob xwm yeem, txoj hauj lwm qhov kev pab no tseem uas qhia ib sib downward nyob rau hauv lub vas nthiv. Tsis nti li no xwb ces tsis pub dhau qhov ntawd los, ntau yam yog coj xub mus daws teeb meem kev tseem ceeb.

Third, coj ntim, thermal

Thermal tsim ntawm tus LED pob yog muab raws tus txheej txheem LED ntau lawm. 2 daim duab qhia cov LED pob thermal tsim cov txheej txheem kev co, uas yog nti thermal thiab cov qauv siv ntim. Ua li no, los tsim kev thiab meej pem yuav fee LED qhia rau cua sov thiab cua txias.

Plaub, tus LED ntawm qhov txias lwm yam ntsiab

Kom heev high-power LED, ua raws li nws nti pob thermal tsim yog tsau, siv tsis raug hloov, yog li no thaum uas siv thaum muaj teeb pom kev zoo nyob rau hauv roj uas yuav tsum tau mus raws li cov kev ua hauj lwm mob thiab tus mob uas ua hauj lwm kev tsim lwm yam tshuaj thermal.
