Makrolon® LED2245 EL (edge lighting) illuminates up EV-Rearlamp vision
Automotive designers and engineers face challenges balancing aesthetics, functionality, material limitations, and regulatory requirements. Traditional solutions often compromise design freedom, hindering sleek, slim, visually appealing systems. HASCO´s vision sought an innovative, space-saving solution for rear lights where the design posed heat resistance and flexibility challenges for some materials.
The challenge was finding a material meeting contradictory requirements:
- robustness against temperature within design and regulatory boundaries;
- specific color when non-illuminated;
- yet high transparency, light-guiding properties and brightness, for homogeneous surface illumination when illuminated.
The solution was to intelligently combine material properties and color-optical properties, ensuring optimal light distribution while meeting specified requirements.
Makrolon® LED2245 EL meets our requirements and enables the light design also in high temperatures without design changes.
Through close collaboration with HASCO, Covestro developed an innovative functional color solution utilizing Makrolon® LED2245 EL polycarbonate. This advanced material enabled integrating the light source at the edge of the light distribution layer, facilitating a space-saving design with homogeneous surface illumination. The very low haze level allowed deep, transparent red coloration, ensuring regulatory compliance. Exhibiting exceptional temperature resistance, Makrolon® LED2245 EL maintained optimal optical performance under demanding conditions.
