High-Precision Convex Lenses for LED Headlights | Foshan Geqin Auto Parts

Foshan Geqin Auto Parts specializes in manufacturing precision convex lenses specifically designed for LED headlight applications. These optical components utilize high-grade polycarbonate (PC) or polymethyl methacrylate (PMMA) materials with exceptional light transmission properties (90%+ for PC, 92%+ for PMMA). The convex lenses are engineered to optimize LED light output by precisely controlling beam patterns and minimizing light loss. We manufacture lenses with carefully calculated curvature radii (typically 50-300mm) to achieve desired focal lengths for various LED lighting configurations. Our production process maintains tight tolerances (±0.05mm on optical surfaces) to ensure consistent optical performance across all units. The lenses feature UV-resistant formulations that prevent yellowing under prolonged exposure to LED emissions. We offer various diameter options (30-200mm) with precise center thickness control for different headlight designs. The convex lenses incorporate specialized anti-reflective coatings that enhance light transmission efficiency for LED systems. Our quality control includes comprehensive photometric testing to verify beam pattern compliance with ECE/SAE standards. The lenses demonstrate excellent thermal stability, maintaining performance at LED operating temperatures up to 120°C. We can customize solutions for specific LED chip configurations and optical requirements.
