LED-Based Headlight Meets US Safety Requirements, Reduces Energy Consumption

Facebook Twitter LinkedIn Email Comments
TAIWAN, Feb. 22, 2018 — Researchers have designed an LED-based train headlight that uses one-tenth of the energy required for headlights that use conventional light sources. If operated eight hours every day, the electricity savings of the new design could reduce emissions of the greenhouse gas carbon dioxide by about 152 kg per year. Researchers at National Taiwan University report a new train headlight design based on ten precisely positioned high-efficiency LEDs. The researchers combined the small outputs of multiple high-efficiency LEDs into a large circular output to create a beam large enough to meet or...Read full article
