Abstract:
A light emitting device package including a substrate; a light emitting device on the substrate; a first heatsink between the substrate and the light emitting device to transfer heat generated from the light emitting device; a second heatsink disposed below the first heatsink; and an electrode between the first heat sink and the light emitting device. Further, the substrate is disposed between the first and second heatsinks and is narrower at a position between the first and second heatsinks than at a position not between the first and second heatsinks, a material of the substrate is the same at the position between the first and second heatsinks as not between the first and second heatsinks, and the substrate at the position not between the first and second heatsinks surrounds the first and second heat sinks.
