Lighting has certainly changed since its invention by Thomas Edison in the 19th century. Today, we see LED bulbs everywhere: in homes, offices, airplanes, and telephones. Many hail the arrival of this technology as revolutionary for the industry, yet the potential of LED technology extends far beyond mere lighting. With the fast and constant evolution of this technology, soon, lighting will become a secondary function to the lighting system.

The integration of LEDs within electronic products such as speakers and WiFi signal boosters has become more and more common. LED lights will soon be able to deliver what is known as LiFi, which is a wireless Internet access via the lighting system. (Wireless Fidelity or WiFi will become Lighting Fidelity or LiFi).

The connected lamp will fulfill several functions. Not only will it illuminate, but it will also transmit data via the Internet through light waves. Thus, light will be used to capture and send information to other systems that control the atmosphere of a given space such as temperature, air quality, occupancy, monitoring, etc.

The Advantages and Inconveniences of LiFi

The Advantages
  • Less harmful to health. In addition to avoiding the use of radio waves that are potentially harmful to human health, LiFi can also be a substitute for 3G or cable connections.
  • Reduced the risk of hacking. LiFi is also very secure because, unlike WiFi, it cannot pass through walls. Data exchange would remain confined to lit areas, thus putting an end to the threat of hackers!
  • Very high speed. LiFi technology can provide a download speed of over 30Mbps, which is up to 10,000 times faster than the majority of traditional WiFi bandwidths.
The Inconvenience
  • Limit of Connection. A benefit can also be an inconvenience depending on the circumstances. As the connection is wireless, it requires that you be within the radiance of the light to remain connected. In other words, you would lose your Internet connection by leaving the room that is connected via LiFi

Imagine the future

In the near future, we will be living in a world where travelling businessmen and businesswomen will enter a hotel or office and program the atmosphere by using lighting and their smartphone. Imagine your smartphone communicating with an LED lighting systems to set any ambience you choose: soft lighting, ideal temperature, perfect music… exactly as if you were in your own office.

You can transform any room into your office!

    What you seem to be referencing seems to be more with using the lighting circuitry to deploy an advanced, intelligent sensor technology that optimizes the environment based on human occupancy. That technology has been on the market for about ten years now (Enlighted, Daintree…). Their technology is totally independent of the lighting technology in use.

    • Indeed, something similar does exist, but it’s an additional system. Here’s we’re talking about an integrated system within the lighting system itself: space saving, cost saving, without diminishing the efficiency.

    • I think, Li fi is about carrying the data on light waves emitted from a LEDBulb. This is a new technology just tried out of Labs. Exceptionally fast data transmission is achieved… almost 3gb per second.
