We have independently developed professional Fresnel lens design software. This software can directly solve the lens size and generate a three-dimensional model through projection effects and light source types. It replaces the previous proximity algorithm that was constantly debugged and adjusted in optical simulation software. The calculation of the software has already been based on the light source. Based on the model, the light distribution curve is calculated by analyzing the luminous flux at each angle, and then the brightness of each point of the lens is calculated based on the projected brightness distribution. The software can calculate two types of ring distances: equal pitch and equal thickness, and two working surfaces: flat and curved. , ensuring design accuracy.
