Abstract
The main body of the main unit has a light-receiving surface, a light-reflecting surface, and a light-projecting surface. The reflecting unit includes a plurality of reflecting microstructures formed on the light-reflecting surface. Each reflecting microstructure has a first reflecting curved surface, and the first reflecting curved surface of each reflecting microstructure has a first reflecting curved line shown on the lateral surface thereof. The first reflecting curved line of each first reflecting curved surface is substantially composed of a first base point as an initial point on the first bottom portion of the light-reflecting surface, a second base point as an end point on the second bottom portion of the light-reflecting surface, and a first curve track connected from the first base point to the second base point and passing through a plurality of first trajectory points.
