摘要： A light guide lens includes: an outer surrounding surface that extends between a front surface disposed at an optical axis, and a rear end formed with a recess that has an end surface disposed at the optical axis, and an inner surrounding surface extending rearward from a periphery of the end surface. The outer surrounding surface diverges forwardly along the optical axis, and includes first and second pairs of curved surface parts, the first pair being disposed mutually asymmetrical on opposite sides of an imaginary plane, the second pair being disposed mutually symmetrical on opposite sides of another imaginary plane and extending between the first pair. The end surface includes a third pair of curved surface parts disposed mutually asymmetrical on opposite sides of yet another imaginary plane.
