In this paper, we have been analyzed the thermal-fluid flow and structural stress of high power Light-emitting diode (LED) lighting system for outdoor lighting. Thermal and Structural performances of LED lighting systems were designed using computer aided engineering (CAE) and after securing their structural and thermal safety, simulated in order to develop 400 W high-efficiency LED floodlight. The temperature of LED was shown to rise up to 136 degrees C. This means that the cooling system should be improved. Maximum strain was detected in the glass, yet they appeared largely safe. 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. Which measured the lifetime of the lighting equipment has passed.
在本文中，我们分析了用于户外照明的高功率发光二极管（LED）照明系统的热流体流动和结构应力。利用计算机辅助工程（CAE）设计了LED照明系统的热性能和结构性能，并在确保其结构和热安全性后进行了模拟，以开发400W高效LED泛光灯。结果显示LED的温度上升到了136摄氏度。这意味着冷却系统需要改进。在玻璃中检测到了最大应变，但它们在很大程度上看起来是安全的。设计时重点关注散热片很重要。关于LED的寿命，在测试优化风冷结构的设计时，有必要制定一个将误差最小化的计划。已通过对照明设备寿命的测量。
