Within the area of development of Li-Fi data/audio transmission, the need has arisen to achieve greater energy savings in transmission. This because of the limited power storage resources of mobile devices or difficulty storing energy in extreme conditions (eg. satellites).
Technical SLUX's solution
The SLUX solution allows a considerable energy saving – in the range of about 90% – thanks to the use of environmental visible or non-visible light.
This result, filed with Patent No. 00314/16, is obtained by altering the optical properties of certain materials as a function of the signal which it intends to transmit, for example using the ability of electrochromic materials to change their absorption spectrum after the application of electrical current.
This change is perceptible at a distance and represents a real and true optical wireless transmission.
A transmission between two satellites that receive natural sunlight and the "load" of information transmitted between them without the need to emit their own light source (with a considerable energy saving in such conditions).
Any piece of clothing (a jacket, a hat, a dress...), a vehicle (a car, a plane, a ship...), infrastructure (a building, a street, a street lamp...) which modulates the environmental light and transmits the desired information.
A smartphone that captures light rays from a wall to which the SLUX paint, capable of performing a modulation in the reflection spectrum, has been applied.
1. The energy saving permits a significantly longer battery life for mobile devices that need to send data. In the booming "internet of things" this system could be extended to all transmitting elements with a much lower energy impact (lower absorption in transmission) and ecological impact (spare batteries).
2. This result is even more crucial in difficult charging conditions (space operations etc.).
3. Electrosmog-free: no electromagnetic Wi-Fi emissions, in full compliance with the green philosophy of the near future.
4. The SLUX surface/paint also allows the creation of transmitting surfaces of any kind without any being equipped with optical transmission equipment with active light emission. This aspect therefore increases the range of transmission for these everyday objects that weren’t created specifically as transmitting devices, therefore aiding the relentless spread of the "Internet of things".
