New invention: Wi-fi light bulb

Chinese scientists have invented the world's first light bulb capable of generating Wi-fi signals.

A group of researchers at the University of Easter in Shanghai City (China) has developed a new technology LED light , named Li-Fi , capable of emitting Wi-fi signals. Experts say this bulb works better than Wi-fi broadcast systems that are in common use in China.

According to Gizmodo magazine, four technology devices located near Li-Fi bulbs can connect to Wi-fi signals using light frequencies instead of radio waves. A microchip mounted lamp can emit signals at a rate of 150 Mbps, faster than the average Wi-fi connection in China.

Scientists will introduce Li-Fi light bulb models and devices at the Shanghai International Industrial Fair next month.

Experts identify how this fast, cheap and energy-efficient way to connect to the Internet can be widely used by families in China, as more and more people are switching to using traditional light bulbs.

Li-Fi bulbs are said to use only 5% of energy compared to other Wi-fi transmitters. Popular Wi-fi transmitters now depend on cooling systems to provide internet to stations.

Although new technology fits Chinese technology trends, developers still have problems with design and production, especially in IC design. In addition, Wi-fi connection is lost when the light bulb is turned off or the light reaches the device being obscured.
