Abstract:
1. An LED package structure comprising: a substrate; an LED chip; two electrodes engaged in the substrate, each of the electrodes having a top even surface, each of the electrodes defining a groove, each of the grooves of the electrodes being arch-shaped, the grooves surrounding the LED chip and recessing from the top even surface downwardly, wherein the LED chip is mounted on one of the electrodes and electrically connects with the two electrodes; a reflective cup mounted on the substrate and surrounding the LED chip; and an encapsulation covering the LED chip and extending in the grooves of the electrodes to prevent water/moisture from entering the LED chip via a gap between the encapsulation and the electrodes; wherein the reflective cup has an inner wall defining a space receiving the LED chip and the encapsulation, the groove has an inner edge near the LED chip and an outer edge away from the LED chip, and a bottom edge of the inner wall connected to the electrodes is located at a position aligned to outer edges of the grooves of the electrodes.
