Aim at the lacks of uniformity for large view angle illumination in the near-field and low efficiency of single freeform-surface lens of LED, based on the edge-ray theory and grid partition method, a double freeform-lens with large view angle of LED was designed, the inner surface was elliptic and the outer surface was freeform. The incident rays of LED diverge from the inner surface of the lens, and the direction of the emergent rays were controlled by the outer surface, which realized large view angle uniform illumination and reduces losses of total reflection, thus, improving the luminous efficiency. The extended source ray-file was employed to do optical simulation for the lens model, the feedback optimization method was used to optimize the outer surface and improve uniformity of near-field illumination. The results show that under the condition of same near-field distance, with the beam angles at 143°and 151.8°, respectively, the corresponding illumination uniformity values of single freeform-surface lens are 0.55 and 0.40, and the efficiency values are 92.0% and 80%.While the proposed double freeform-surface lens greatly improve illumination effects, with 0.84 and 0.85 illumination uniformity and 98.8% and 95.0% efficiency.
