An LED package structure includes a heatsink slug, a positive-electrode frame, a negative-electrode frame, and an LED module electrically connected with the positive-electrode frame and the negative-electrode frame. The LED module includes a plurality of LED chips. The heatsink slug is provided, at its surface, with a plurality of cup-like recesses. The plural LED chips are each bonded, correspondingly, on a plane in the cup-like recess. Each of the LED chips is covered with a fluorescent colloidal layer having a curved and convex contour. As a result, a specific proportion for the color lights emitted from all the LED chips and from the fluorescent material in every direction of a space can be maintained, and that a better spatial color uniformity can be achieved.
