Patent ID: 7438445

Claim:
A packaging lens, adapted for guiding a light entering into said packaging lens along an optical axis of said packaging lens to be emitted from side surfaces of said packaging lens, comprising: an incident surface, being passed through by said optical axis; a reflective surface, reflecting a portion of said light entering into said packaging lens through said incident surface to proceed along a direction perpendicular to said optical axis; a first refractive surface, having multiple continual zigzag surfaces, and said zigzag surface having multiple refractive surfaces separately parallel or perpendicular to said optical axis to enable said portion of said light reflected by said reflective surface to vertically penetrate said first refractive surface and then to proceed along a first optical path; and a second refractive surface, refracting the other portion of said light entering into said packaging lens through said incident surface to emit from said side surfaces of said packaging lens and then proceed along a second optical path.
