Abstract

This study is focused on verification through lens design and simulation to achieve rectangular light distribution when a light-emitting-diode light source is applied to the bottom surface using the aspherical lens. The lens profile was designed using Visual C++, VisualLISP, and AutoCAD, and a glass mold was formed to mold the glass lens based on the designed profile. The Illuminating Engineering Society (IES) photometric data format file was acquired through the integrating sphere to measure the light distribution of the processed glass lens. Moreover, the IES file for simulation was generated using TracePRO based on the designed profile. The square light distribution IES file was developed at a 3.5 m height in a 12 m × 6 m space area, and maximum uniformity of 0.79 was obtained.


Keywords: Uniformity (Emin/Em (Uo)), Aspheric lens, Simulation, COB (chip on board), Square light distribution
