Abstract :
A novel CNT/SiC/epoxy composite was proposed and demonstrated as adhesive joining element and heat dissipation media for HB-LEDs. Junction temperature, luminous intensity and forward voltage were measured for varied combinations in the composites. The experimental results showed that the epoxy with 30 wt% of SiC and 5 wt% of MWCNTs had the best thermal properties. Comparing to commercial epoxy, the CNT/SiC/ epoxy could decrease junction temperature from 123°C to 93°C and thermal resistance from 81°C /W to 65°C/W.
