Abstract: A method for assembling LEDs to a ceramic heat conductive piece comprises: mixing ceramic materials together and subjecting the mixed ceramic materials to hot pressing to form the ceramic heat conductive piece, the ceramic heat conductive piece has a cold end; subjecting the cold end of the ceramic heat conductive piece to sliver printing, drying process and silver reduction process to form the silver layer; choosing conductive binders, and applying the conductive binders to the silver layer by coating process; attaching the LEDs between paired conductive binders by welding; getting a finished product. The structure produced by the method is such that the LEDs are located between the paired conductive binders, and each of the LEDs includes a LED wafer disposed on a substrate, so that the heat generated by the LEDs can be transmitted quickly to the ceramic heat conductive piece via the conductive binders and the silver layer.
