Problems solved by technology

[0008] The above is the current status of thermal performance testing of semiconductor lighting products. The heat dissipation performance of semiconductor lighting products cannot be systematically and effectively obtained through the current methods and patents, and thermal performance comparisons between products with different structures cannot be carried out. These severely limit semiconductor lighting products. R&D, manufacturing and industrialization development
