Low-Beam Headlight Lens Arrays for Sharp Diaphragm-Free Borders

The patent removes the diaphragm component entirely from the optical system. Instead of using a physical diaphragm to create the light-dark boundary, the invention uses an asymmetric optical design with specifically shaped optical elements (such as asymmetric lenses or reflectors) that directly shape the light distribution to produce the required light/dark border without any absorbing components.

The patent replaces the mechanical diaphragm system with an optical beam-shaping system. The light distribution is controlled through the geometric design and positioning of optical elements rather than through a physical mask, substituting a mechanical blocking approach with an optical shaping approach that maintains transmission.

The patent converts the potential harm of heat generation by removing the absorbing diaphragm. The optical system is designed to achieve the same light-dark boundary function through refraction and reflection by asymmetric optical elements, which do not absorb significant energy, thereby eliminating the heat problem associated with diaphragm-based solutions.

The patent divides the single aperture optical system into multiple apertures or optical channels. By using an array of optical elements (such as a microlens array or multiple asymmetric optical units), the system achieves the required light distribution in a more compact configuration, effectively reducing the focal length and overall structural length while maintaining or improving performance.

The patent transitions from a single-aperture one-dimensional optimization to a multi-aperture two-dimensional array configuration. This dimensional change allows the system to achieve compact focal lengths by distributing the optical function across multiple elements in an array, effectively folding the optical path and reducing the overall system length.

The patent applies different optical characteristics to different regions of the optical system. The asymmetric optical elements are designed with locally optimized surface profiles and geometries that specifically address the light distribution requirements of each region, ensuring smooth transitions at boundaries and eliminating the interfering artifacts that occur with uniform honeycomb structures.

The patent employs asymmetric optical element designs instead of symmetric honeycomb structures. The asymmetric geometry of the optical elements naturally directs light paths to avoid interference at junctions, eliminating the light artifacts problem while maintaining effective beam shaping and collimation capabilities.
