Lately, a research team from Taiwan's National Defense University has been utilizing nanocarbon materials to develop lightbulbs and tubes that are more energy-efficient and environmentally friendly than currently available products.

Unlike LED lighting products, the team's invention boasts nanocarbon materials that can be used to develop a light source in a mercury-free manufacturing process, according to Ger Ming-der, a professor at the university's Department of Chemical and Material Engineering at Chung Cheng Institute of Technology. The technology also has a simple structure and features a high degree of luminous efficiency, as well as better color rendering, Ger added.

Another feature of the new invention is that it can be integrated into the country's traditional lightbulb industry.

Currently, he and his team have received a local patent for their invention. Ger disclosed that, “We're seeking more cooperative opportunities with private businesses to improve our invention so that it can be mass produced.”
