Convex lenses from Foshan Geqin Auto Parts are used in various critical automotive lighting applications. These optical components are primarily employed in headlight systems to control and direct light output from various sources (halogen, HID, LED). The convex lenses are used to create specific beam patterns required by regulatory standards, including precise cutoff lines for low beam applications. In fog light systems, convex lenses are used to produce wide, flat beam distributions that enhance visibility in poor weather conditions. The lenses are used in daytime running light (DRL) systems to create distinctive lighting signatures with efficient light distribution. In auxiliary driving lamps, convex lenses are used to concentrate light for long-distance illumination. The optical components are also used in turn signal and position light applications to enhance visibility and meet photometric requirements. Our convex lenses are used with various light source technologies, each requiring specific optical designs to optimize performance. The lenses are used in both exterior lighting and interior illumination applications where controlled light direction is required. We can provide customized convex lens solutions for specialized automotive lighting applications not covered by standard offerings.
