摘要：
An LED device with improved LED efficiency is presented. An LED die is positioned within a pocket formed by a substrate and an opening in a supporting layer arranged thereon. The increase in the LED efficiency is achieved by providing a device where at least a portion of the pocket surface is reflective. This portion of the pocket surface is reflective because it is covered by either a reflective layer of foil or film, or a reflective coating, or it is polished.
