1. A packaging structure for plural bare chips, comprising: a substrate having a supporting surface; a reflective layer arranged on the supporting surface and having a plurality of through holes; a plurality of bare light-emitting chips arranged on the reflective layer and corresponding to the through holes; and a transparent light guide covering the bare light-emitting chips and the reflective layer, with the transparent light guide having a light-outputting layer on a side of the transparent light guide facing away from the supporting surface, with the light-outputting layer parallel to the supporting surface and having a light gathering member, with the light gathering member being in a form of plural ridges, wherein an included angle of a tip of each ridge is in a range between a first angle and a second angle, with the first angle being twice a sum of a critical angle and 20 degrees, and with the second angle being twice a difference of the critical angle and 20 degrees, wherein the critical angle is in the transparent light guide for a boundary between the transparent light guide and air.
