Structural and thermal performances of LED floodlight luminaires were designed using computer aided engineering (CAE) and then, after securing their structural and thermal safety, simulated in order to develop 400W high-efficiency LED floodlight luminaires. Maximum strain was detected in the glass, yet they appeared largely safe. An analysis of its radiation observed the highest temperature (94 οC) around the case cooling fin. Thus, it is important for the design to focus on the cooling fin. Regarding the lifespan of LED, it is necessary to have a plan for minimizing errors when testing designs for optimizing air cooling structures.
