AB - Thermal management had an important influence not only in the life time but also in the efficiency ofhigh power light emitting diodes (HPLEDs). 30 watts in a single package have become standard to theindustrial fabricating of HPLEDs. In this study, we fabricated both of the AlN porous films, by vacuumsputtering, soldered onto the HPLEDs lamp to enhance both of the heat transfer and heat dissipation. Inour model, the ceramic enables transfer the heat from electric device to the aluminum plate quickly andthe porous increase the quality of the thermal dissipation between the PCB and aluminum plate, ascompared to the industrial processing. The ceramic films were characterized by several subsequentanalyses, especially the measurement of real work temperature. The X-Ray diffraction (XRD) diagramanalysis reveals those ceramic phases were successfully grown onto the individual substrates. Themorphology of ceramic films was investigated by the atomic force microscopy (AFM). The results showthose porous films have high thermal conduction to the purpose. At the same time, they had transferredheat and limited work temperature, about 70℃, of HPLEDs successfully.
