1. A package structure, comprising:
a substrate;
an electrode layer disposed on the substrate;
a lighting unit disposed on the substrate and electrically connected to the electrode layer, wherein the lighting unit has a top surface and a surrounding lateral surface connected to a peripheral edge of the top surface;
a wall disposed on the substrate, wherein the wall and the substrate jointly define an accommodating space, and the lighting unit is disposed in the accommodating space; and
a light-permeable package compound disposed in the accommodating space and covering the lighting unit, wherein the light-permeable package compound includes:
an attaching portion adhering to the top surface of the lighting unit; and
a surrounding portion being a one-piece continuous layer with the attaching portion; and
a reflective layer disposed in the accommodating space, covering at least a part of the electrode layer and being covered by the light-permeable package compound, wherein the reflective layer has a first curved surface, the first curved surface has a center of a curvature defined by a circle, the center of the curvature is arranged outside of the accommodating space;
wherein a top surface of the surrounding portion is in a curved shape so as to define as a second curved surface, and the second curved surface has a center of a curvature defined by a circle, the center of the curvature is arranged outside of the accommodating space, and wherein the curvature of the first curved surface is greater than the curvature of the second curved surface.
