| Abstract |
Simulation plays a crucial role in optical design, allowing for the rough predictions of light distribution and irradiance without the need for physical fabrication. Conventional simulation approaches often rely on trial-and-error to identify optimal solutions; however, this can be both time-consuming and costly. To overcome these challenges, obtaining an approximate solution as an initial estimate and refining through simulation can be a more efficient strategy in terms of both time and cost. In this study, a reflector was designed to uniformly distribute light emitted from a UV-C LED with a Lambertian profile onto a target area. This was achieved by calculating three-dimensional spatial vectors. The resulting design served as the initial input for simulations to determine the optimal solution. As a result, the overall simulation time was significantly reduced, and the proposed method enabled the straightforward derivation of initial simulation parameters without requiring complex calculations. |
