Automated optimization of an aspheric light-emitting diode lens for uniform illumination

Abstract

In this paper, an automated optimization method in the sequential mode of ZEMAX is proposed in the design of an aspheric lens with uniform illuminance for an LED source. A feedback modification is introduced in the design for the LED extended source. The user-defined merit function is written out by using ZEMAX programming language macros language and, as an example, optimum parameters of an aspheric lens are obtained via running an optimization. The optical simulation results show that the illumination efficiency and uniformity can reach 83% and 90%, respectively, on a target surface of $40\mathrm{mm}$ diameter and at $60\mathrm{mm}$ away for a $1\times 1\mathrm{mm}$ LED source.
