More specifically, for convenience of explanation of the curvature change of the light exit surface 32 of the aspherical lens 3 of the present invention, one virtual spherical lens is configured based on the aspherical lens 3, and the spherical lens extends from the center of the lens. It has a constant curvature to the edge, and the central curvature of the light exit surface of the spherical lens is the same as the central curvature of the light exit surface 32 of the aspherical lens 3, as shown in FIGS. , the solid line in the figure is the central longitudinal transverse line 33 or the central transverse transverse line 34 of the aspherical lens 3, and the dashed line is the longitudinal transverse line or transverse transverse line at the corresponding position of the spherical lens. Compared with the conventional spherical lens, the curvature change law of the middle curve of the central transverse transverse line 34 of the aspheric lens 3 is the same as the curvature change law of the middle curve of the transverse transverse line at the corresponding position of the spherical lens. However, the curvatures of the left and right curves of the central transverse transverse line 34 of the aspherical lens 3 are both greater than the curvatures of the left and right curves of the transverse transverse line at the corresponding positions of the spherical lens. Because of the large size, the light exit direction of the left and right parts of the aspherical lens 3 is to exit in the direction approaching the optical axis 35, and the left curve and right part of the central lateral transverse line 34 of the aspherical lens 3 Since the curvature of the curve first increases along the direction away from the optical axis 35 and then decreases, the amplitudes of the exiting light on the left and right sides of the aspherical lens 3 first increase upon approaching the optical axis 35. , then decreases, i.e., if the curvature increases, the light tends to project in a direction gradually approaching the optical axis 35, and if the curvature decreases, the light tends to project in a direction gradually approaching the optical axis 35. is projected in a direction away from the optical axis 35.

More preferably, as shown in FIG. 10, any one longitudinal cross section of the aspherical lens 3 and the light exit surface 32 of the aspherical lens 3 intersect to form one longitudinal transverse line 33. , the longitudinal transverse line 33 has a curvature change boundary point that is an arbitrary point between the midpoint and the upper end point of the longitudinal transverse line 33, and the position of the curvature change boundary point depends on the desired light shape. can be adjusted. For convenience of explanation, the curve from the curvature boundary point to the upper end point of the vertical transverse line 33 is called the upper curve, and the curve from the curvature boundary point to the lower end point of the vertical transverse line 33 is called the middle lower curve. Called. As a preferred structural form, the middle and lower curves of the longitudinal transverse line 33 have the same curvature, the upper curves of the longitudinal transverse line 33 have the same curvature, and the curvature of the upper end point of the longitudinal transverse line 33 is the same in the longitudinal direction. The curvature of the lower end point of the transverse line 33 is smaller than the curvature of the lower end point of the longitudinal transverse line 33. As another preferred structural form, the curvature of the middle and lower curves of the longitudinal transverse line 33 is equal, and the curvature of the upper curve of the longitudinal transverse line 33 is from the optical axis 35. It gradually becomes smaller along the direction of separation. More specifically, compared with a conventional spherical lens, the change rule of the middle-lower portion of the longitudinal transverse line 33 of any one of the aspherical lenses 3 is Same as the law of variation, the curvature of the upper curve of the longitudinal transverse line 33 of the aspherical lens 3 is less than the curvature of the upper curve of the longitudinal transverse line at the corresponding position of the spherical lens. When a conventional spherical lens is used to project light, the light exits in a direction substantially parallel to the optical axis 35 of the spherical lens, and the high beam light shape formed is shown in FIG. are symmetrically distributed within the upper and lower vicinity areas of the , and do not meet the regulatory requirements for high beam light shape. As shown in FIG. 14, when projecting light using an aspherical lens 3, the same light exits from the longitudinal transverse line 33 of the aspherical lens 3 rather than exiting from the upper curve of the longitudinal transverse line of the spherical lens. , the exit direction is farther from the optical axis 35, most of the formed high beam light shape is above the horizontal 0 degree line and the upward diffusion angle is very large, and the light shape range meets regulatory requirements for high beam light shaping.

Preferably, the aspherical lens 3 is a biconvex lens, and the light incident surface 31 protrudes rearward along the optical axis 35 of the aspherical lens 3 , thus allowing the sunlight to irradiate the aspherical lens 3 . The focal point formed when doing so is closer to the aspherical lens 3 and further away from the bezel, thereby avoiding burnout of the bezel. Of course, the aspherical lens 3 may be a plano-convex lens, a concave-convex lens, or the like.

The aspherical lens in the preferred embodiment of the present invention is based on a spherical lens, the light exit surface 32 of said aspherical lens 3 being such that the curvature of the central curve of the central transverse transverse line 34 is at the corresponding position of the spherical lens. and the curvature of the left curve of the central transverse transverse line 34 of the aspherical lens 3 and the curvature of the right curve of the central transverse transverse line 34 are both in the direction away from the optical axis 35 first increases, then decreases, and decreases until it equals the curvature of said mid-curve, i.e., the left end point overlaps the corresponding left end point of the spherical lens, and the right end point coincides with the corresponding right end point of the spherical lens. and the curvature of the middle and lower curve of the longitudinal transverse line 33 of the aspheric lens 3 is equal to the curvature of the spherical lens, and the curvature of the upper curve of the longitudinal transverse line 33 of the aspheric lens 3 is from the optical axis 35 It is configured to become progressively smaller along the direction of separation. For the aspherical lens 3 in the preferred embodiment of the present invention, the curved surface is formed by sweeping using the central longitudinal transverse line of the aspherical lens 3 as a contour line and the central transverse transverse line 34 of the aspherical lens 3 as a guide line. Alternatively, the central horizontal transverse line 34 of the aspherical lens 3 is divided into a plurality of sub-segments, and the vertical transverse line 33 of the aspherical lens 3 passing through the dividing points of each sub-segment is defined as a contour line, and The light exit surface 32 of the aspherical lens 3 is constructed by sweeping the corresponding sub-segments of the central lateral transverse line 34 as a guide line and connecting a plurality of sweep surfaces to form the light exit surface 32. In this way, the light exit surface 32 can be divided into multiple sweep surfaces, and during the design of the light exit surface 32, the parameters of each sweep surface can be easily adjusted to fine-tune the light shape produced. In such a configuration, there are a plurality of longitudinal transverse lines 33 as contour lines, and the curvature of the upper curve of the longitudinal transverse lines 33 is greater than the curvature of the longitudinal transverse line at the corresponding position of the spherical lens. Under the condition of being small, the curvature of the upper curve of each longitudinal transverse line 33 can be different, and the position of the curvature change boundary point of each longitudinal transverse line 33 can also be adjusted according to the required light shape.

In the structure of the aspherical lens 3 in the preferred embodiment of the present invention, a light source 1 is provided at the focal point of the aspherical lens 3, together with the light emitted from the light source 1, the refraction law of the aspherical lens 3 is explained in more detail. do.

Both of the two curvature boundary points are set at the midpoint of the central transverse transverse line 34, and the curvatures of the left and right curves of the central transverse transverse line 34 are both at the midpoints of the central transverse transverse line 34. On the other hand, it first increases and then decreases along the direction away from the optical axis 35, so that the ray L3 approaches the optical axis 35 because the curvature at the point of refraction of L3 is greater than the curvature at the midpoint. Since the curvature of the position of the refracting point of the light L4 is larger than the curvature of the position of the refracting point of the light L3, the light L4 is emitted in a direction closer to the optical axis 35 than the light L3, and the light L5 is smaller than the curvature of the refracting point of the light L4, the light L5 is emitted in a direction away from the optical axis 35 than the light L4, and the curvature of the refracting point of the light L6 is smaller than that of the light L6. Since the curvature is smaller than the position of the refracting point of L5, the light L6 emerges in a direction further away from the optical axis 35 than the light L5, i.e., emerges along a direction substantially parallel to the optical axis 35, thus The aspherical lens 3 diffuses the received light upward, and can project and form a more uniform light shape with a bright central region. In the optical path diagrams of FIGS. 10 and 11, the light source 1 is an optical path that directly hits the aspherical lens 3 and is not condensed by the condensing element 21.
