A lens cap and an LED package structure using the same are provided. The lens cap includes a cap body made of a transparent material for being covered on a point light source. The cap body includes a first incident surface, which is a curved surface raised on a inner side of the cap body and refracts light emitted by the point light source into the cap body. A reflective surface is formed the outer side of the cap body and is opposite to the first incident surface, wherein the reflective surface reflects the light refracted by the first incident surface. A light-transmitting surface is formed on the outer side of the cap body, and the light reflected by the reflective surface is projected onto the light-transmitting surface to exit the cap body. Thus, the light is emitted towards the lateral of the lens cap along a horizontal direction.
