Abstract

The deep-sea environment is characterized by high pressure, low temperature and high salinity, and the absorption and scattering of water molecules and suspended particles will have an impact on the light environment in the deep-sea domain, posing requirements and challenges to the design and application of deep-sea lighting technology. The stable energy supply, reliability and durability of deep-sea lighting equipment are prerequisites for the sustainable development of deep-sea lighting technology at this stage. The current status of research and application of deep-sea lighting technology is summarized, including light source technology, pressure-resistant technology, sealing and anticorrosion technology, through comparison, analysis, and summary of existing deep-sea lighting technologies.The future research is suggested to be focused on enhancing anticorrosion materials, improving heat dissipation performance, developing pressure-resistant materials, and advancing light source technology. The aim is to provide more reliable and efficient lighting solutions for scientific research, marine resource development, and engineering operations in deep-sea environments, thereby promoting the continuous development and exploration of the deep-sea field.
