Patent ID: 7746565

Claim:
An optical package comprising: a base substrate; a point light source on the base substrate; and an optical lens covering the point light source, the optical lens including: a recessed part having a substantially V shaped cross-section, a light incident into the recessed part being totally reflected from the recessed part; and a refracting part refracting a light incident into the refracting part and reflected light from the recessed part toward a front of the optical package, wherein the refracting part comprises: a first flat surface extended from a side of the recessed part, the first flat surface being connected to an outer periphery of the recessed part and disposed substantially perpendicular to a vertical line which is substantially perpendicular to a bottom surface of the optical lens; a first curved surface extended from a side of the first flat surface, the first curved surface being connected to an outer periphery of the first flat surface; and a second flat surface extended from a side of the first curved surface, the second flat surface substantially parallel with the vertical line perpendicular to the base substrate, the second flat surface being connected to an outer periphery of the first curved surface, and wherein light incident on the recessed part is totally reflected to the refracting part, the light refracted from each of the first, second, and third surfaces, and wherein each of the first flat surface, the first curved surface and the second flat surface has a single ring shape when viewed in perspective.
