Embodiment 1

[0040] Such as figure 1 and Figure 4 As shown, the optical lens provided by the embodiment of the present invention includes: a convex lens 20, and the curved side of the convex lens 20 includes a grid area 21, and the grid area 21 is formed by splicing a plurality of polygonal light-transmitting planes.

[0041] The optical lens of the embodiment of the present invention is applied in the lighting device, when the optical lens of the embodiment of the present invention is applied in the optical module of the car light of the automobile, because in the optical lens provided by the embodiment of the present invention, the curved surface of the convex lens 20 The side includes a grid area 21, and the grid area 21 is formed by splicing a plurality of polygonal light-transmitting planes, that is to say, a curved surface formed by splicing a plurality of light-transmitting planes is used to replace the smooth curved surface of the convex lens 20 in the prior art, Since the angles...

Embodiment 2

[0069] Embodiment 2 of the present invention provides a vehicle lamp, and the optical module of the vehicle lamp is provided with the optical lens provided in Embodiment 1 above.

[0070] Since the curved surface side of the convex lens arranged in the optical lens is provided with a grid area, the grid area is formed by splicing a plurality of light-transmitting planes.

[0071] Therefore, when the vehicle lamp provided in the second embodiment is a low beam lamp with a cut-off function, compared with the low beam lamp with a cut-off function in the prior art, the lamp provided in the second embodiment can effectively improve the low beam The gradient and dispersion of the cut-off line can reduce the gradient of the cut-off line for low beams, making the cut-off line softer and reducing the dispersion problem.

[0072] When the car light provided in the second embodiment is a matrix headlight, compared with the matrix headlight in the prior art, in the car light provided in t...

Abstract

The invention provides an optical lens and a car lamp, and relates to the technical field of car lamps. The problems that the edge of a light type separation line of a car lamp is sharp, chromatic dispersion is serious, and pixel light spots in a matrix type headlamp are uneven in brightness are solved. The optical lens comprises a convex lens, and the curved surface side of the convex lens comprises a grid zone which is formed by splicing a plurality of polygonal light transmitting planes. When the optical lens is applied to a dipped headlight having a separation line function, the gradient of a dipped beam separation line can be reduced, thus, the edge of the separation line is gentle, and chromatic dispersion is reduced. When the optical lens is applied to a transmission-type matrix headlamp, the connection uniformity between pixels can be improved.

Description

technical field [0001] The invention relates to the technical field of vehicle lamps, in particular to an optical lens and a vehicle lamp. Background technique [0002] Currently, in headlights, especially low beam lights with a cut-off line function, usually because the gradient is too high, the cut-off line boundary is very sharp, and usually has obvious dispersion. In matrix headlights, there will be obvious uneven brightness and darkness among multiple pixel spots, and dark stripes will appear to varying degrees in both horizontal and vertical directions. [0003] The dispersion and unevenness of light and shade of the headlights will affect the driving experience. Contents of the invention [0004] The object of the present invention is to provide an optical lens to solve the technical problems existing in the prior art that the cut-off line boundary of the light type of the car lamp is sharp, the dispersion is serious, and the brightness among the pixel spots in the...
