摘要：An LED device includes a substrate having a top surface, an LED chip arrangedon the top surface of the substrate, an encapsulant arranged on the top surface of the
substrate and covering the LED chip, and an optical element arranged over theencapsulant. The optical element includes a light input surface adjacent to the
encapsulant and a light output surface opposite to the light input surface. The refractiveindex of the optical element is larger than that of the encapsulant.
