The present invention provides a primary lens including a main body portion 110 including a first optical surface 111 and a second optical surface 112, and a linear focus is formed on the first optical surface 111 The height of the first optical surface 111 gradually decreases from the focus line 113 to the two sides, and the second optical surface 112 includes a plurality of ribs 114 arranged in parallel, and the extending direction of the ribs 114 is vertical. At the focus line 113, the rib 114 has a circular arc-shaped convex surface.

As shown in FIG. 4, the focus line 113 is the highest on the first optical surface 111, and the heights on both sides are gradually lowered to be a convex convex surface; as shown in FIGS. 3 and 5, the circular convex surface of the rib 114 It may be regarded as a partial outer peripheral surface of the cylindrical structure, and the extending direction of the rib 114 is parallel to the central axis direction of such a cylindrical structure.

When the primary lens 100 is applied to a vehicle lamp, the primary lens 100 can be placed such that the focal line 113 can extend substantially in the horizontal direction, and the rib 114 extends in the vertical direction, and the light source can be placed on the side of the first optical surface 111. The first optical surface 111 can serve as an incident surface, and the second optical surface 112 can serve as an exit surface. The first optical surface 111 can cause incident light to converge toward the intermediate focus line 113 in the vertical direction, and the second optical surface 112 can make The incident light forms an outgoing light that is diffused in the horizontal direction. That is to say, through the first optical surface 11 and the second optical surface 112, the light beams generated by the light source can be concentrated in the vertical direction and diffused in the horizontal direction, which is more suitable for the horizontal illumination range of the vehicle lamp is relatively large, A relatively small range of vertical illumination.

In addition, the adjacent ribs 114 are smoothly transitioned by the arcuate concave surface 115. As shown in FIG. 3, the rib 114 itself is formed with a circular arc-shaped convex surface, and two adjacent circular arc-shaped convex surfaces can be connected by a circular arc-shaped concave surface 115 to achieve a smooth transition, that is, the circular arc shape The convex line coincides with the tangent of the arcuate concave surface at the joint. Wherein, the central axis of the arcuate concave surface 115 may be parallel to the central axis of the circular arc convex surface, in particular, the diameter of the circular arc concave surface 115 is much smaller than the diameter of the circular arc convex surface, that is, the main portion of the second optical surface 112 The circular arc-shaped convex surface realizes the diffusion of light in the horizontal direction by the circular arc convex surface, and the circular arc concave surface 115 is only a smooth connection of two circular arc-shaped convex surfaces, and the area ratio is negligible, and the optical effect thereof is also Can be ignored.

In addition, since the second optical surface 112 is provided with a plurality of ribs 114, the radius of the circular arc-shaped convex surface is smaller than the dimension of the second optical surface 112 in the horizontal direction. Relatively small, the diffused light formed by the second optical surface 112 in the lateral direction is relatively uniform.
