Answer
Lighting is the primary application of Hiroshi Amano's invention. His groundbreaking work in the development of blue light-emitting diodes (LEDs) revolutionized the lighting industry. LEDs offer superior energy efficiency, longer lifespans, and more compact designs compared to traditional lighting sources. They have become ubiquitous in various applications, including general lighting, automotive lighting, and display technologies. Amano's invention has significantly reduced energy consumption and improved the overall quality of lighting.
