An adjustable high‐flux LED solar simulator based on dome structure

Energy Science &Engineering, Volume 12, Issue 9, Page 3895-3906, September 2024.
A radiation unit with an LED–TIR structure is designed, and a high‐density spherical cap layout model is proposed to optimize its distribution. On the basis of this design, an adjustable high‐flux solar simulator is constructed. Abstract High‐flux solar simulator (HFSS) commonly serves as a vital instrument for conducting material testing and ...
