'LiFi' uses LEDs for blazing fast data transfer

A new technology called LiFi can transfer data using LED lights. In this video, we’ll watch a demo of a LiFi system made with off-the-shelf-parts, as it streams a vide.
Unlike traditional Wi-Fi routers, which use radio signals, this LiFi system relies on light to send and receive data wirelessly. If you notice an Ethernet cable plugged into the laptops that’s just to get the data from the receiver into the computer.
The problem with Wi-Fi is that it uses radio signals and the amount of radio spectrum is limited. LiFi, however, could be deployed in everyday LED bulbs and cover the entire interior of a home or office. The system on show ran at 150 Mbps, but with a more powerful LED light, it could reach 3.5 Gbps.
Don’t expect LiFi to be in your home or office any time soon. Researchers ay it will take another five years before the technology is ready for commercialization.

There are a number of differences between LED bulbs and regular bulbs. The main difference is that the LEDs are not really bulbs, but small semiconductors that are usually separated by a plastic dome. The dome plays a vital role in focusing light on a specific area, and also protects the emitted light from interference. On the other hand, regular light bulbs usually have a filament that glows red hot when power is applied.

LED light bulbs moments. Ok sounds a bit weird, but in this case it just means that you consider switching your old, energy hungry bayonet or screw in bulbs with newer and more energy efficient LED light bulbs.

Led lights are the future for a greener world, a necessasity that must be handed over to legacy,
it also saves our present by both CO2 reduction and Huge reduction on monthly bills.
As estimated approximately 90% reduction in electric bills and huge savings.
