In this work, a light grid system with a high-power LED chip was manufactured and employed to analyze the energy efficiency of output optical energy. The high-power LED system based on thermoelectric modules, a heat dissipation structure and optical transmission system with an optical fiber were optimally combined and designed, which increased the efficiency of light grid system. Additionally, by introducing an effective design for the heat dissipation structure, the output optical energy and recycled electrical energy were increased. The recycled energy through optimized heat dissipation structure was 1.94 W, and the system efficiency of designed light grid system is more than 50%. In this research, we intensively studied the energy efficiency of a light grid system as well as the recycling of thermal energy through thermoelectric modules.
