HUD PGU lens

Introduction to the Optical Design Process with CATIA and SPEOS CATIA, a leading CAD software, offers powerful modeling capabilities that enable the rapid construction of LED light source arrays. With its intuitive interface and advanced geometric modeling tools, designers can quickly create complex LED configurations according to specific project requirements. Moreover, in conjunction with SPEOS, users have access to a comprehensive database containing various LED models. This allows for precise setting of light source parameters, ensuring accurate simulation and optimization of the lighting system. When it comes to the design of PGU backlighting, SPEOS provides a useful feature called OST (Optical Component Quick Construction Function). This function enables the creation of TIR (Total Internal Reflection) lenses, which play a crucial role in collimating the light source. By leveraging OST, designers can efficiently develop lenses that direct the light in a desired manner, enhancing the performance of the backlighting system. The OSD (Optical System Designer) in SPEOS adopts a parametric design mode. This innovative approach allows users to simply input optical parameters, and the software will immediately construct the required optical components. This significantly reduces the design time and effort, while also ensuring high precision in the design process. To achieve the best light source uniformity, SPEOS can be used in combination with CATIA's Design Table function. This integration enables the optimization of OSD's optical parameters, allowing designers to fine-tune the lighting system for optimal performance. After optimizing the light source, multiple array mirrors are employed to mix the light and control the light pattern angle. This step is essential for achieving a more even and consistent light distribution. Subsequently, a diffuser is used to further homogenize the light, ensuring that the illumination is smooth and free from hotspots or shadows. Finally, SPEOS' 3D Texture function comes into play. This function allows for the design of various microstructures on optical films, enabling the adjustment of the light pattern to make the light rays more collimated. Through this comprehensive process, the combination of CATIA and SPEOS provides a powerful solution for optical design, enabling the creation of high-performance lighting systems with precise control over light distribution and quality.
