This study reports the use of aluminum nitride(AlN) ceramics as a heat dissipated interface material to enhance the thermal performance of light-emitting diode (LED) packages. AlN ceramics are coated on copper/aluminum substrates by electrostatic spraying. The 18 orthogonal arrays of the LEDs with a signal-to-noise ratio are adopted and the impact of the effect of the spraying parameters on the AlN coatings is examined. Using an optimized design, the thermal performance of the LED is improved and good heat resistance characteristics are achieved. A confirmation run is used to compare results with the overall experimental tests. The results show that using AlN ceramic coating on a heat sink yields a good the thermal performance.
