The manufacturing of LED lenses follows a highly precise and technologically advanced workflow to meet stringent quality standards:
Design engineers utilize CAD software coupled with ray-tracing tools (LightTools, Zemax) to create lens geometries that optimize light output, beam shape, and uniformity. Simulations address thermal effects, optical distortions, and light intensity distributions.
Rapid prototyping, such as 3D printing or CNC machining, allows quick evaluation of lens designs under real-world conditions, adjusting shapes or materials before committing to mold fabrication.
Precision molds are manufactured using hardened steel with surface polish finishes for injection molding. High-precision molds reduce defects and enhance repeatability, crucial for mass production.
Optical-grade plastics like PMMA (polymethyl methacrylate) and PC (polycarbonate) are molded under controlled temperature and pressure. Korean factories employ advanced injection molding machines equipped with real-time monitoring to ensure consistent lens thickness and clarity.
Anti-reflective coatings and protective layers are applied to improve optical performance and environmental resistance. New nano-coatings reduce glare and improve light transmission.
Depending on design, lenses may require assembly with other optical components. Rigorous quality tests—such as light distribution measurement, dimensional accuracy, UV resistance, and mechanical stress tests—are conducted within ISO-certified cleanrooms.
Final products are carefully packed in protective, dust-free materials to prevent contamination or damage during logistics.
Automation plays a key role across production stages. SMT (Surface Mount Technology) lines and robotics improve efficiency and product consistency. Specialized additive dispensing systems deposit adhesives precisely for multi-part lens assembly, while UV curing ensures strong, uniform bonds.
