Summary: By studying various aspects of LED packaging, such as substrate material, structure, chip distribution, and array form, the heat dissipation capacity of the package can be improved. It is found that changing substrate material and structure has a significant impact on heat dissipation, while changing array forms has little effect. By improving the spatial distribution of the chips, the temperature superposition problem of the substrate can be solved, resulting in improved illuminance and uniformity.

Summary: This study investigates the impact of shade structures on thermal comfort in Thai street markets. The results show that tree canopies provide better cooling effects compared to artificial shade structures. Galvanized steel roofing and HDPE tarpaulin plastic roofing shades are more effective than polycarbonate roofing shade. Spaces under sparse tree canopies have the highest temperatures. The temperature reductions beneath the artificial shade structure vary throughout the day.
