Abstract：With the development of LED lighting technology towards high power,high precision,miniaturization and other directions,LED heat dissipation effect has become the key factor restricting LED lighting technology.This paper employs the Box-Behnken Design(BBD)experimental methodology,utilizing five heat dissipation factors—surface heat transfer coefficient(h),fin length(L),fin height(H),number of fins(N),and ambient temperature(T)—as variables.The maximum(M)and minimum(m)values of the temperature distribution during LED heat dissipation serve as response indicators.A five-factor,three-level simulation experiment with two responses is designed.Heat dissipation simulations are performed on the experimental data,and the resulting data are integrated to formulate multivariate regression fitting equations.Based on significance analysis,the impact laws of structural parameters of the 15W LED heatsink on its thermal performance are summarized,and the optimal structural parameters for the 15W LED heatsink are determined.
