Vehicle lamp module and lens

Abstract

The invention relates to a lens including a light input surface and a light output surface. The light output surface is opposite to the light input surface. A central region of the light output surface has a plurality of cylindrical surface microstructures. A depth of the cylindrical surface microstructures in a direction parallel to an optical axis of the lens is within a range from 0.02 millimeter to 0.2 millimeter. A vehicle lamp module is also provided.

Description

technical field

[0001] The present invention relates to a light source module and an optical element, and particularly relates to a vehicle light module and a lens. Background technique

[0002] Most current headlight lens designs (such as headlight designs using light-emitting diodes (LEDs) as light sources) mostly use a single lens design. According to the principle of optics, the thickness ratio of the lens will produce different degrees of dispersion.

[0003] Generally, to solve the color shift problem, a doublet lens is used. This kind of lens is to glue two positive and negative lenses of materials with different dispersion capabilities to solve the dispersion problem. However, this method will reduce the optical efficiency, increase the weight and manufacturing cost, and may increase the length of the back focal length, thereby affecting the system volume. In addition, the adhesive material used between the two lenses will also have reliability doubts, such as dete...
