Short summary

This study tackles overheating in deep-sea LED fish-attracting lamps under extreme heat. A new cooling approach combines special surface patterns, chimney airflow, and heat pipes. The lamp housing is reshaped to channel heat efficiently from the light source to the outer shell. Fine surface textures at key contacts further improve heat flow. Tests show this reduces peak temperature by 6.73% compared to conventional designs, offering an effective solution for high-power underwater lighting.
