Design of LED Lighting System with Improved Color Mixing Uniformity [PDF]

Chih-Ching Hung, Hsin-Hung Lin, and Ching-Hui Chen

(Received October 20, 2023; Accepted April 10, 2024)

Keywords: uniformity of mixed light, LED, chip array, lighting module

We explored the uniformity of light mixing, optical component design, and the directional orientation of the LED projection angles in a new LED lighting system design. To validate the design, we simulated the LED array performance using LightTools software with relevant parameters. The simulation result showed the collimation of light projections of the proposed LED lighting system. At the angles of LED projection from 0 to 30°, better and more uniform RGB three-color light mixing than those of conventional light systems was obtained. Experiments were conducted to confirm the simulation result by constructing a real model that was smaller than the model design for simulation. The results confirmed the collimation. The proposed LED lighting system showed uniform and vivid colors in large areas.
