Abstract:
1. A light module, from a light side to an object side, comprising: a light source for emitting light toward the object side; and an optical lens having a first plane, a parallelizing surface, a wave surface having smooth troughs and crests, and a second plane in sequence from the light side to the object side; wherein the light from the light source enters the optical lens via the first plane and leaves the optical lens via the parallelizing surface, and then the light re-enters the optical lens via the wave surface and leaves the optical lens via the second plane to form a linear light; wherein the linear light is compressed so as to form a flatly diffused and linear light contained within a thickness of the optical lens in a vertical direction, and an angle between two opposite outermost side edges of the linear light is greater than 90 degrees in a horizontal direction.
