Abstract

See full text

A lens of an LED package structure includes a square-shaped base layer, a first light-guiding portion integrally connected to the base layer, a second light-guiding portion taperedly extended from the first light-guiding portion. The second light-guiding portion has an apex located away from the first light-guiding portion. The lens includes four side curved surfaces and four boundary curved surfaces connected to the apex. Four first projecting regions are defined by orthogonally projecting the four boundary curved surfaces onto the base layer, and the four first projecting regions are arranged on two diagonals of the base layer. Any two adjacent boundary curved surfaces are provided with one of the side curved surfaces there-between. Each boundary curved surface has a first radius of curvature (R1), a portion of each side curved surface arranged on the second light-guiding portion has a second radius of curvature (R2), wherein R1/R2=M√{square root over (2)} and M=0.8˜1.2.
