| Introduction | A light collector includes: a light guide; optical blocks, each of which has top and bottom surfaces and front and rear surfaces which extend curvedly and frontwardly from the top surface to the bottom surface, the rear surface exhibiting total internal reflection and having a focal point; and optical coupling protrusions, each of which protrudes from the bottom surface, each of which is disposed at the focal point and each of which is coupled to the light-entrance surface of the light guide. The front surface of one of every two adjacent ones of the optical blocks overlaps the rear surface of the other of every two adjacent ones of the optical blocks along a normal direction of the light guide. |
