碩士 / 國立中央大學 / 光電科學研究所 / 100 / Before executing Taguchi method, we must estab¬lish the five parameters such as the number of fins and the fin thickness, the fin height, the fin thickness of substrate, the radiation material on surface. First, the above five parameters must be determined. Next, these parameters are divided into four levels separately in order to reduce the maximum temperature of LED street light .
This research using Taguchi Method makes the optimization of LED street light heat sink easier whereas the simulation times of the 5 parameters and the 4 levels of each parameter will be in total 1024 times. We establish a product that can effectively re¬duce simulation times to 16. The maximum temperature of LED street light is lower than all of probable combination exactly.
The original design of heat sink without optimization by Taguchi method, the maximum temperature of heat sink is 48.817℃. With the optimal optimization design we can reach the maximum temperature is 37.321℃,the temperature of sink is significantly decreased. Moreover the optimization by Taguchi method design can get the best construction in a short time. Therefore, this research for the cooling components decreases development time and the cost of production. We believe this research will be helpful for thermal design of LED street light.
