Abstract

SSL lighting requires precise design and fabrication of optical components to control the direction, intensity, and spread of light. Achieving high color rendering index and color temperature consistency while balancing heat management and light extraction efficiency is crucial but challenging. NanoVox has developed a cost-effective inkjet print gradient index optics additive manufacturing platform to create SSL optics with non-symmetrical refractive index distributions, providing more efficient control over light distribution and color balance. Detailed manufacturing processes and examples of structured freeform GRIN optics designed for SSL applications are presented.
