Abstract:
A light emitting diode (LED) package includes an aluminum nitride (AlN) substrate, a patterned copper layer with polished portions formed on a first side of the substrate, at least one LED disposed over the polished portions of the patterned copper layer, covers incorporating one or more phosphors disposed over the LEDs, a silicone fill and dam walls. The silicone fill, which is bordered by silicone dam walls and silicone fill surfaces, is formed in between the LEDs and covers. In some embodiments, the silicone fill does not extend over the covers. The silicone fill surface and the ends of the dam walls are substantially planar with an end of the substrate. The LED package can also include a thermal pad disposed on an opposite side of the substrate. Embodiments also include methods for make the LED package.
