Abstract
An illumination apparatus comprises a heat sink, at least one light module and an insulating adhesive layer. The light module is disposed on the heat sink, and the insulating adhesive layer is disposed between the light module and heat sink to combine the light module with the heat sink. The insulating adhesive layer comprises polymer component and heat conductive filler dispersed therein. The polymer comprises thermoset epoxy resin. The insulating adhesive layer has heat conductivity greater than 0.5 W/m-K and a thickness of 0.02-10 mm. The bonding strength of the insulating adhesive layer to the heat sink and the light module is greater than 300 g/cm, and the insulating adhesive layer can withstand a voltage of at least 500 volts.
