Revolutionary Streetlight Coating Reflects 95% of Light While Allowing 80% of Infrared Heat to Escape

Researchers at Saudi Arabia’s King Abdullah University of Science and Technology (KAUST) and King Abdulaziz City for Science and Technology (KACST) have developed a groundbreaking nanomaterial called nanoPE to enhance the efficiency of LED streetlights while reducing their carbon emissions. This innovative material, made from polyethylene and engineered with 30-nanometer pores, allows over 80% of infrared light—generated as waste heat—to escape while reflecting more than 95% of visible light downwards for effective illumination. By addressing the heat generation issues associated with traditional LED technologies, nanoPE has the potential to lower carbon dioxide emissions in the United States by up to one million metric tons. This development highlights the significant impact that simple design changes in street lighting can have on achieving a more sustainable future.
