ABSTRACT:
A light source and method for making the same are disclosed. The light source includes a substrate, a die, and a cup. The substrate has a plurality of electrical traces thereon and the die includes an LED that is connected to two of the traces. The cup overlies the substrate and is filled with an encapsulant material. The die is located within the cup and is encapsulated by the substrate and the encapsulant material. The cup and encapsulant material have substantially the same coefficient of thermal expansion. The cup can include reflective sidewalls positioned to reflect light leaving the die. The cup, encapsulant and substrate can be constructed from the same material.
