Tsim ntawm intrinsically kev nyab xeeb circuits thiab theem nrab kub dissipation
(1) LED yog cov khoom siv tam sim no. Kev ua haujlwm tam sim no muaj kev sib raug zoo nrog cov hluav taws xob thiab kev ua haujlwm luminous. Ntawd yog, qhov loj dua qhov ua haujlwm tam sim no, qhov siab dua qhov hluav taws xob, thiab ntau dua qhov kev ua haujlwm luminous. Txawm li cas los xij, tshaj qhov ntsuas kev ua haujlwm tam sim no yuav ua rau lub neej luv luv. Thaum qhov hluav taws xob tau nce ntawm 3.1 V mus rau 3.42 V (rated khiav hauj lwm voltage), tam sim no hloov mus txog 250 mA nrog kev hloov pauv ntawm 781 mA / V. Nws tuaj yeem pom tau tias qhov kev ua haujlwm tam sim no muaj kev cuam tshuam rau kev hloov pauv, thiab Cov kev hloov tam sim no ncaj qha cuam tshuam Lub luminous efficiency ntawm LEDs yuav tsum muaj kev nyab xeeb intrinsically thaum tsim circuits thiab khaws cov zis tas li mus rau LED terminals.
(2) Cov teeb meem cua txias thib ob
Rau lub tshav kub dissipation ntawm LED, ib cheeb tsam loj nti flip-chip qauv, hlau Circuit Court board qauv, ib tug kub conduction zawj qauv, thiab ib tug microfluidic array qauv yog siv nyob rau hauv lub ntim qauv. Nyob rau hauv cov nqe lus ntawm kev xaiv cov khoom, xaiv ib tug haum substrate khoom thiab muab tshuaj txhuam, thiab siv silicone resin. Es tsis txhob epoxy. Txawm li cas los xij, qhov thib ob cua sov dissipation ntawm LED teeb pom kev zoo tseem yog qhov teeb meem tseem ceeb hauv kev tsim cov teeb pom kev zoo tam sim no. Cov kev ntsuas uas tuaj yeem ua tau yog kho cov LED diodes ntawm Al phaj lossis Al ntawv; Tom qab ntawd, Al phaj lossis Al daim ntawv yog tsau rau lub vaj tsev nrog cov roj thermal ua ke, cov cua sov tsim los ntawm LED diodes yog sai sai dissipated los ntawm lub tsev. Cov kev sim tau ua pov thawj tias cov nyhuv zoo heev thiab ua tau raws li cov kev xav tau ntawm lub teeb emission thiab txuag hluav taws xob.
